57 2002-11-11 Paul Eggert <eggert@twinsun.com>
58
59 Revamp to fix many (but not all) of the C- and M4-related quoting
60 problems. Among other things, this fixes the Bison bug reported
61 by Jan Hubicka when processing the Bash grammar; see:
62 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html>
63
64 Use new @ escapes consistently. Represent brackets with @{ and @}
65 rather than @<:@ and @:>@, since this works a bit better with dumb
66 editors like vi. Represent @ with @@, since @ is now consistently
67 an escape. Use @oline@ and @ofile@ rather than __oline__ and
68 __ofile__, to avoid unexpected expansions. Similarly, use @output
69 rather than #output.
70
71 * data/c.m4 (b4_copyright): Omit file name from comment, since
72 the file name could contain "*/".
73 (b4_synclines_flag): Don't quote the 2nd argument; it should already
74 be quoted. All uses changed.
75
76 * data/glr.c: Use new @ escapes consistently.
77 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
78 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
79 Remove, since they couldn't handle arbitrary characters in file
80 names.
81 * data/lalr1.cc: Likewise.
82 * data/yacc.c: Likewise.
83
84 * src/files.c (output_infix): Remove; all uses removed.
85 * src/files.h: Likewise.
86
87 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
88 mishandled funny characters in file names, and anyway it isn't
89 needed any more.
90 * data/yacc.c: Likewise.
91 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
92
93 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
94 * data/yacc.c: Likewise.
95
96 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
97 strings now.
98 (muscle_init): Quote filename as a C string.
99 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
100 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
101 * src/output.c (escaped_file_name_output): New function.
102 (prepare_symbols): Quote tokens for M4.
103 (prepare): Don't insert output_infix, output_prefix,
104 output_parser_name, output_header_name; this is now down by scan-skel.
105 Insert skeleton as a C string.
106
107 * src/output.c (user_actions_output, symbol_destructors_output,
108 symbol_printers_output): Quote filenames for C and M4.
109 * src/reader.c (prologue_augment, epilogue_set): Likewise.
110
111 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
112 escapes other than \\ and \'; this simplifies the code.
113 (<SC_STRING>): Likewise, for \\ and \".
114 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
115 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
116 Use new escapes @{ and @} for [ and ].
117
118 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
119 them with auto vars.
120 Switch to new escape scheme, where @ is the escape character uniformly.
121 Abort if a stray escape character is found. Avoid unbounded input
122 buffer when parsing non-escaped text.
123
124 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
125 __oline__, #output, $@, and @{ do not have unintended meanings.
126
127 2002-11-09 Paul Eggert <eggert@twinsun.com>
128
129 Fix the test failure due to GCC warnings described in
130 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>.
131 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
132 evaluate to 0 if it's impossible for NINF to be in the respective
133 table.
134 (yygetLRActions, yyrecoverParseError): Use them.
135
136 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
137 counted in the token inserted at end of file. Now takes
138 location_t *, not location_t, so that the location can be
139 adjusted. All uses changed.
140
141 * tests/regression.at (Invalid inputs): Adjust wording in
142 diagnostic to match the new behavior.
143
144 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
145 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
146 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
147 abort ();'. This reduces the runtime of the "Many lookaheads"
148 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
149 GCC 3.2.
150
151 2002-11-07 Paul Eggert <eggert@twinsun.com>
152
153 * src/parse-gram.y (CHARACTER): Remove unused token.
154 All uses removed.
155
156 * src/scan-gram.l: Remove stack option. We no longer use the
157 stack, since the stack was never deeper than 1; instead, use the
158 new auto var c_context to record the stacked value.
159
160 Remove nounput option. At an unexpected end of file, we now unput
161 the minimal input necessary to end cleanly; this simplifies the
162 code.
163
164 Avoid unbounded token sizes where this is easy.
165
166 (unexpected_end_of_file): New function.
167 Use it to systematize the error message on unexpected EOF.
168 (last-string): Now auto, not static.
169 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
170 (scanner_last_string_free): Remove; not used.
171 (percent_percent_count): Move decl to just before use.
172 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
173 not the (never otherwised-used) CHARACTER.
174
175 2002-11-07 Akim Demaille <akim@epita.fr>
176
177 Let yyerror always receive the msg as last argument, so that
178 yyerror can be variadic.
179
180 * data/yacc.c (b4_yyerror_args): New.
181 Use it when calling yyerror.
182 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
183 Use it when calling yyerror.
184 * doc/bison.texinfo (Error Reporting): Adjust.

187
188 2002-11-06 Akim Demaille <akim@epita.fr>

191 Ideally, this should be done by m4_quotearg.
192
193 * src/scan-skel.l: Include quotearg.h.
194 Quote __ofile__.
195 * src/output.c (symbol_printers_output)

197
198 2002-11-06 Akim Demaille <akim@epita.fr>
199

201 messages.
202
203 2002-11-06 Akim Demaille <akim@epita.fr>
204
205 Restore --no-lines.
206 Reported by Jim Kent.
207
208 * data/c.m4 (b4_syncline): New.
209 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
210 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
211 * src/output.c (user_actions_output): Likewise.
212 (prepare): Define 'b4_synclines_flag'.
213 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
214
215 2002-11-06 Akim Demaille <akim@epita.fr>
216
217 * src/main.c (main): Free `infile'.
218 * src/scan-gram.l (handle_syncline): New.
219 Recognize `#line'.
220 * src/output.c (user_actions_output, symbol_destructors_output)
221 (symbol_printers_output): Use the location's file name, not
222 infile.
223 * src/reader.c (prologue_augment, epilogue_set): Likewise.
224
225 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
226
227 * src/tables.c (matching_state): Don't allow states to match if
228 either has GLR conflict entries.
229
230 2002-11-05 Paul Eggert <eggert@twinsun.com>
231
232 * src/scan-gram.l: Use more accurate diagnostics, e.g.
233 "integer out of range" rather than "invalid value".
234 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
235 accordingly.
236
237 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
238 Also, remove one static variable in the scanner.
239
240 * src/scan-gram.l (braces_level): Now auto, not static.
241 Initialize to zero if the compiler is being picky.
242 (INITIAL): Clear braces_level instead of incrementing it.
243 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
244 as POSIX 1003.1-2001 requires.
245 * src/system.h (IF_LINT): New macro, taken from coreutils.
246 * configure.ac: Define "lint" if --enable-gcc-warnings.
247
248 2002-11-05 Akim Demaille <akim@epita.fr>
249
250 * src/scan-gram.l: When it starts with `%', complain about the
251 whole directive, not just that `invalid character: %'.
252

254
255 * Makefile.maint: Update from Autoconf.

261 and yyerror.
262 Have yyerror `use' its arguments.
263 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
264 returns true when location & yacc & pure & parse-param.
265 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
266
267 2002-11-04 Akim Demaille <akim@epita.fr>
268
269 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
270 clashes.
271 * src/scan-gram.l: Use [\'] instead of ['] to pacify
272 font-lock-mode.
273 Use complain_at.
274 Use quote, not quote_n since LOCATION_PRINT no longer uses the
275 slot 0.
276
277 2002-11-03 Paul Eggert <eggert@twinsun.com>
278
279 * src/reader.c (get_merge_function, grammar_current_rule_check):
280 Use consistent diagnostics for reporting type name clashes.

282 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
283
284 2002-11-03 Akim Demaille <akim@epita.fr>
285
286 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
287 New.
288 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
289 (b4_parse_param): Remove.
290 Use b4_identification.

293 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
294 (b4_lpure_formals): New.
295 Use b4_identification.

325
326 2002-11-03 Paul Eggert <eggert@twinsun.com>
327

347 all uses changed.
348 (tag, splice): New EREs. Do not allow NUL or newline in tags.
349 Use {splice} wherever C allows backslash-newline.
350 YY_STEP after space, newline, vertical-tab.
351 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
352
353 (letter, id): Don't assume ASCII; e.g., spell out a-z.
354
355 ({int}, handle_action_dollar, handle_action_at): Check for integer
356 overflow.
357
358 (YY_STEP): Omit trailing semicolon, so that it's more like C.
359
360 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
361 as well as \000. Check for UCHAR_MAX, not 255.
362 Allow \x with an arbitrary positive number of digits, as in C.
363 Check for overflow here.
364 Allow \? and UCNs, for compatibility with C.
365
366 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
367 with quote slot used by complain_at.
368
369 * tests/input.at: Add tests for backslash-newline, m4 quotes
370 in symbols, long literals, and funny escapes in strings.
371
372 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
373 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
374 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
375 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
376 * m4/mbswidth.m4: New file, from GNU coreutils.
377
378 * doc/bison.texinfo (Grammar Outline): Document // comments.
379 (Symbols): Document that trigraphs have no special meaning in Bison,
380 nor is backslash-newline allowed.
381 (Actions): Document that trigraphs have no special meaning.
382
383 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
384 no longer used.
385
386 2002-11-02 Paul Eggert <eggert@twinsun.com>
387
388 * src/reader.c: Don't include quote.h; not needed.
389 (get_merge_function): Reword warning to be consistent with
390 type clash diagnostic in grammar_current_rule_check.
391
392 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
393 bug in trigraph handling.
394
395 * src/output.c (prepare_symbols): When printing token names,
396 escape "[" as "@<:@" and likewise for "]".
397
398 * src/system.h (errno): Remove declaration, as we are now
399 assuming C89 or better, and C89 guarantees errno.
400
401 2002-10-30 Paul Eggert <eggert@twinsun.com>
402
403 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
404 Check for close failures.
405 * src/files.h (xfclose): Return void, not int, since it always
406 returned zero.
407 * src/files.c (xfclose): Likewise. Report I/O error if ferror
408 indicates one.
409 * src/output.c (output_skeleton): Use xfclose rather than fclose
410 and ferror. xfclose now checks ferror.
411
412 * data/glr.c (YYLEFTMOST_STATE): Remove.
413 (yyreportTree): Use a stack-based leftmost state. This avoids
414 our continuing battles with bogus warnings about initializers.
415
416 2002-10-30 Akim Demaille <akim@epita.fr>
417
418 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

422
423 * tests/glr-regr1.at: New test for reported regressions.
424 * tests/testsuite.at: Add glr-regr1.at test.
425 * tests/Makefile.am: Add glr-regr1.at test.
426
427 2002-10-24 Paul Eggert <eggert@twinsun.com>
428
429 Version 1.75a.
430
431 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
432 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
433 we use malloc. Don't assume 'A' through 'Z' are contiguous.
434 Don't assume strdup exists; POSIX says its an XSI extension.
435 Check for buffer overflow on input.
436
437 2002-10-24 Akim Demaille <akim@epita.fr>
438
439 * src/output.c (output_skeleton): Don't disable M4sugar comments
440 too soon: it results in comments being expanded.
441 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
442 first output.
443
444 2002-10-24 Akim Demaille <akim@epita.fr>
445
446 * data/yacc.c (m4_int_type): New.
447 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
448 char' as only yacc.c wants K&R portability.
449 * data/glr.c (yysigned_char): Remove.
450 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
451 Reported by Quoc Peyrot.
452
453 2002-10-23 Paul Eggert <eggert@twinsun.com>
454
455 * src/main.c (main): With --trace=time, report times even if a
456 non-fatal error occurs. Formerly, the times were reported in some
457 such cases but not in others.
458 * src/reader.c (reader): Just return if a complaint has been issued,
459 instead of exiting, so that 'main' can report times.
460
461 2002-10-22 Akim Demaille <akim@epita.fr>
462
463 * src/system.h: Include sys/types.
464 Reported by Bert Deknuydt.
465
466 2002-10-23 Paul Eggert <eggert@twinsun.com>
467
468 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
469 Suggested by Art Haas.
470
471 2002-10-22 Paul Eggert <eggert@twinsun.com>
472
473 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
474 decl; not needed any more.
475 * src/main.c (main): Use return to exit, undoing yesterday's change.
476 The last OS that we could find where this wouldn't work is
477 SunOS 3.5, and that's too old to worry about now.
478
479 * data/glr.c (struct yyltype): Define members even when not
480 doing locations. This is more consistent with yacc.c, and it
481 works around the following bug reports:
482 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
483 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
484 and I hope it also fixes this bug report:
485 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
486
487 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
488 @acronym consistently. Standardize on "Yacc" instead of "YACC",
489 "Algol" instead of "ALGOL". Give a bit more history about BNF.
490
491 2002-10-22 Akim Demaille <akim@epita.fr>
492
493 * data/README: New.
494
495 2002-10-21 Paul Eggert <eggert@twinsun.com>
496
497 Be consistent about 'bool'; the old code used an enum in one
498 module and an int in another, and this violates the C standard.
499 * m4/stdbool.m4: New file, from coreutils 4.5.3.
500 * configure.ac (AC_HEADER_STDBOOL): Add.
501 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
502 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
503 * src/symtab.c (hash_compare_symbol_t): Likewise.
504 * src/system.h (bool, false, true): Use a definition consistent
505 with ../lib/hash.c. All uses changed.
506
507 * src/complain.c (warning_issued): Renamed from warn_message_count,
508 so that we needn't worry about integer overflow (!).
509 Now of type bool. All uses changed.
510 (complaint_issued): Renamed from complain_message_count; likewise.
511
512 * src/main.c (main): Use exit to exit with failure.
513
514 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
515 rather than 1 and 0.
516 * src/main.c (main): Likewise.
517 * src/getargs.c (getargs): Likewise.
518 * src/reader.c (reader): Likewise.
519
520 * src/getarg.c (getargs): Remove duplicate code for
521 "Try `bison --help'".
522
523 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
524 What was that "2" for?
525
526 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
527 * src/getargs.c (usage): Likewise.
528
529 * src/getargs.c (getargs): When there are too few operands, report
530 the last one. When there are too many, report the first extra
531 one. This is how diffutils does it.
532
533 2002-10-20 Paul Eggert <eggert@twinsun.com>
534
535 Remove K&R vestiges.
536 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
537 * src/complain.c (VA_START): Remove. Assume prototypes.
538 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
539 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
540 fatal): Assume prototypes.
541 * src/complain.h: Assume prototypes.
542 * src/system.h (PARAMS): Remove.
543 Include <limits.h> unconditionally, since it's guaranteeed even
544 for a freestanding C89 compiler.
545 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
546 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
547
548 2002-10-20 Akim Demaille <akim@epita.fr>
549
550 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
551 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
552 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
553 (yyresolveStates, yyresolveAction, yyresolveStack)
554 (yyprocessOneStack): Use them.
555 (yy_reduce_print): New.
556 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
557
558 2002-10-20 Akim Demaille <akim@epita.fr>
559
560 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
561 arguments and output `void'.
562 (b4_c_function): Rename as...
563 (b4_c_function_def): this.
564 (b4_c_function_decl, b4_c_ansi_function_def)
565 (b4_c_ansi_function_decl): New.
566 Change the interpretation of the arguments: before `int, foo', now
567 `int foo, foo'.
568 * data/yacc.c (yyparse): Prototype and define thanks to these.
569 Adjust b4_c_function_def uses.
570 * data/glr.c (yyparse): Likewise, but ANSI only.
571
572 2002-10-20 Akim Demaille <akim@epita.fr>
573
574 * src/output.c (prepare): Move the definition of `tokens_number',
575 `nterms_number', `undef_token_number', `user_token_number_max'
576 to...
577 (prepare_tokens): Here.
578 (prepare_tokens): Rename as...
579 (prepare_symbols): this.
580 (prepare): Move the definition of `rules_number' to...
581 (prepare_rules): here.
582 (prepare): Move the definition of `last', `final_state_number',
583 `states_number' to...
584 (prepare_states): here.
585 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
586
587 2002-10-20 Akim Demaille <akim@epita.fr>
588
589 * src/tables.h, src/tables.c, src/output.c: Comment changes.
590
591 2002-10-20 Akim Demaille <akim@epita.fr>
592
593 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
594 * data/c.m4: here.
595
596 2002-10-20 Akim Demaille <akim@epita.fr>
597
598 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
599 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
600 `pair'.
601 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
602 `name' to...
603 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
604 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
605 These.
606
607 2002-10-19 Paul Eggert <eggert@twinsun.com>
608
609 Do not create a temporary file, as that involves security and
610 cleanup headaches. Instead, use a pair of pipes.
611 Derived from a suggestion by Florian Krohm.
612 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
613 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
614 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
615 (BISON_PREREQ_SUBPIPE): Add.
616 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
617 Add subpipe.h, subpipe.c.

619 * po/POTFILES.in: Add lib/subpipe.c.
620 * src/output.c: Include "subpipe.h".
621 (m4_invoke): Remove decl.
622 (scan_skel): New decl.
623 (output_skeleton): Use pipe rather than temporary file for m4 input.
624 Check that m4sugar.m4 is readable, to avoid deadlock.
625 Check for pipe I/O error.
626 * src/scan-skel.l (readpipe): Remove decl.
627 (scan_skel): New function, to be used in place of m4_invoke.
628 Read from stream rather than file.
629
630 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
631 float, as this generates a warning on Solaris 8 + GCC 3.2 with
632 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
633 this generates a more-accurate value anyway.
634
635 * lib/timevar.c (timervar_accumulate): Rename locals to
636 avoid confusion with similarly-named more-global.
637 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
638
639 * src/output.c (prepare): Use xstrdup to convert char const *
640 to char *, to avoid GCC warning.
641
642 2002-10-19 Akim Demaille <akim@epita.fr>
643
644 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
645 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
646 Use them to have `calc.y' ready for %pure-parser.
647 * data/yacc.c (YYLEX): Pass a yylex return type to
648 b4_c_function_call.
649
650 2002-10-19 Akim Demaille <akim@epita.fr>
651
652 Prototype support of %lex-param and %parse-param.
653
654 * src/parse-gram.y: Add the definition of the %lex-param and
655 %parse-param tokens, plus their rules.
656 Drop the `_' version of %glr-parser.
657 Add the "," token.
658 * src/scan-gram.l (INITIAL): Scan them.
659 * src/muscle_tab.c: Comment changes.
660 (muscle_insert, muscle_find): Rename `pair' as `probe'.
661 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
662 (muscle_entry_s): The `value' member is no longer const.
663 Adjust all dependencies.
664 * src/muscle_tab.c (muscle_init): Adjust: use
665 MUSCLE_INSERT_STRING.
666 Initialize the obstack earlier.
667 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
668 (muscle_pair_list_grow): New.
669 * data/c.m4 (b4_c_function_call, b4_c_args): New.
670 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
671 * tests/calc.at: Use %locations, not --locations.
672 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
673
674 2002-10-19 Akim Demaille <akim@epita.fr>
675
676 * src/getargs.c (usage): Take status as argument and exit
677 accordingly.
678 Report the traditional `Try ... --help' message when status != 0.
679 (usage, version): Don't take a FILE * as arg, it is pointless.
680 (getargs): When there is an incorrect number of arguments, make it
681 an error, and report it GNUlically thanks to `usage ()'.
682
683 2002-10-18 Paul Eggert <eggert@twinsun.com>
684
685 * data/glr.c (yyreportParseError): Don't assume that sprintf
686 yields the length of the printed string, as this is not true
687 on SunOS 4.1.4. Reported by Peter Klein.
688
689 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
690 * tests/conflicts.at (%nonassoc and eof): Likewise.
691 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
692
693 2002-10-17 Akim Demaille <akim@epita.fr>
694
695 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
696 * src/getargs.c (trace_types, trace_args): Adjust.
697 * src/reader.c (grammar_current_rule_prec_set)
698 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
699 Standardize error messages.
700 And s/@prec/%prec/!
701 (reader): Use trace_flag to enable scanner/parser debugging,
702 instead of an adhoc scheme.
703 * src/scan-gram.l: Remove trailing debugging code.
704
705 2002-10-16 Paul Eggert <eggert@twinsun.com>
706
707 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
708 MUSCLE_TAB_H.
709
710 * NEWS: Officially drop support for building Bison with K&R C,
711 since it didn't work anyway and it's not worth worrying about.
712 * Makefile.maint (wget_files): Remove ansi2knr.c.
713 (ansi2knr.c-url_prefix): Remove.
714 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
715 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
716 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
717
718 2002-10-15 Paul Eggert <eggert@twinsun.com>
719
720 Stop using the "enum_" trick for K&R-style function definitions;
721 it confused me, and I was the author! Instead, assume that people
722 who want to use K&R C compilers (when using these modules in GCC,
723 perhaps?) will run ansi2knr.
724
725 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
726 All uses of "enum_" changed to "enum ".
727 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
728 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
729
730 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

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

796 Version 1.75.
797
798 2002-10-14 Akim Demaille <akim@epita.fr>
799
800 * tests/Makefile.am (maintainer-check-posix): New.
801
802 2002-10-14 Akim Demaille <akim@epita.fr>
803
804 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
805 member.
806
807 2002-10-14 Akim Demaille <akim@epita.fr>
808
809 * src/tables.c (table_ninf_remap): base -> tab.
810 Reported by Matt Rosing.
811
812 2002-10-14 Paul Eggert <eggert@twinsun.com>
813
814 * tests/action.at, tests/calc.at, tests/conflicts.at,
815 tests/cxx-type.at, tests/headers.at, tests/input.at,
816 tests/regression.at, tests/synclines.at, tests/torture.at:
817 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
818 so that the tests still work even if POSIXLY_CORRECT is set.
819 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
820
821 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
822 for portability to K&R hosts. Fix typo: signed char is guaranteed
823 only to 127, not to 128.
824 * data/glr.c (yysigned_char): New type.
825 * data/yacc.c (yysigned_char): Likewise.
826 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
827
828 2002-10-13 Paul Eggert <eggert@twinsun.com>
829
830 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
831 true due to limited range of data type" warning from GCC.
832
833 * data/c.m4 (b4_token_defines): Protect against double-inclusion
834 by wrapping enum yytokentype's definition inside #ifndef
835 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
836
837 2002-10-13 Akim Demaille <akim@epita.fr>
838
839 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
840 Un yy- yyrhs to avoid the name clash with the global YYRHS.
841
842 2002-10-13 Akim Demaille <akim@epita.fr>
843
844 * Makefile.maint: Update from Autoconf 2.54.
845 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
846
847 2002-10-13 Akim Demaille <akim@epita.fr>
848
849 * src/print.c (print_state): Separate the list of solved conflicts
850 from the other items.

853 2002-10-13 Akim Demaille <akim@epita.fr>
854
855 Let nondeterministic skeletons be usable with deterministic
856 tables.
857
858 With the patch, GAWK compiled by GCC without -O2 passes its test
859 suite using a GLR parser driven by LALR tables. It fails with -O2
860 because `struct stat' gives two different answers on my machine:
861 88 (definition of an auto var) and later 96 (memset on this var).
862 Hence the stack is badly corrumpted. The headers inclusion is to
863 blame: if I move the awk.h inclusion before GLR's system header
864 inclusion, the two struct stat have the same size.
865
866 * src/tables.c (pack_table): Always create conflict_table.
867 (token_actions): Always create conflict_list.
868 * data/glr.c (YYFLAG): Remove, unused.
869
870 2002-10-13 Akim Demaille <akim@epita.fr>
871
872 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
873 (O0FLAGS): New.
874 (VALGRIND, GXX): New.
875 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
876 * tests/bison.in: Run $PREBISON a pre-command.
877 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
878 (maintainer-check-g++): New.
879 * Makefile.am (maintainer-check): New.

881 2002-10-13 Akim Demaille <akim@epita.fr>
882
883 * data/glr.c: Formatting changes.
884 Tweak some trace messages to match yacc.c's.
885
886 2002-10-13 Akim Demaille <akim@epita.fr>
887
888 GLR parsers sometimes raise parse errors instead of performing the
889 default reduction.
890 Reported by Charles-Henry de Boysson.
891
892 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
893 check the length of the traces when %glr.
894 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
895 GLR's traces.
896 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
897 Test GLR parsers.
898 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
899 (yyltype): Remove the yy prefix from the member names.
900 (yytable): Complete its comment.
901 (yygetLRActions): Map error action number from YYTABLE from
902 YYTABLE_NINF to 0.
903 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
904 (which was a bug: it should have been YYTABEL_NINF, and yet it was
905 not satisfying as we could compare an YYACTION computed from
906 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
907 only value for error actions.
908 (yyreportParseError): In verbose parse error messages, don't issue
909 `error' in the list of expected tokens.
910 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
911 next action to perform to match glr.c's decoding.
912 (yytable): Complete its comment.

916 Fix problem reported by Henrik Grubbstroem in
917 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
918 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
919 because the Bison parser reads the second action before reducing
920 the first one.
921 * src/scan-gram.l (rule_length): New static var.
922 Use it to keep track of the rule length in the scanner, since
923 we can't expect the parser to be in lock-step sync with the scanner.
924 (handle_action_dollar, handle_action_at): Use this var.
925 * tests/actions.at (Exotic Dollars): Test for the problem.
926
927 2002-10-12 Paul Eggert <eggert@twinsun.com>
928
929 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
930 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
931 Include <sys/time.h> when checking for clock_t and struct tms.
932 Use same include order as source.
933 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
934 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
935
936 * lib/timevar.c: Update copyright date and clarify comments.
937 (get_time) [IN_GCC]: Keep the GCC version for reference.
938
939 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
940 GCC version as of today, then merge Bison's changes.
941 Change "GCC" to "Bison" in copyright notice. timevar.def's
942 author is Akim, so change that too.
943
944 * src/reader.c (grammar_current_rule_check):
945 Don't worry about the default action if $$ is untyped.
946 Prevents bogus warnings reported by Jim Gifford in
947 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
948
949 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
950 * data/glr.c, data/lalr1.cc, data/yacc.c:
951 Output token definitions before the first part of user declarations.
952 Fixes compatibility problem reported by Jim Gifford for kbd in
953 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
954
955 2002-10-11 Paul Eggert <eggert@twinsun.com>
956
957 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
958 (yyparse): here. This undoes some of the 2002-07-25 change.
959 Compatibility problem reported by Ralf S. Engelschall with
960 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
961
962 2002-10-11 Akim Demaille <akim@epita.fr>

966 characters.
967 Reported by Jan Nieuwenhuizen.

973 2002-10-10 Paul Eggert <eggert@twinsun.com>
974
975 Portability fixes for bitsets; this also avoids several GCC
976 warnings.
977
978 * lib/abitset.c: Include <stddef.h>, for offsetof.
979 * lib/lbitset.c: Likewise.
980
981 * lib/abitset.c (abitset_bytes): Return a size that is aligned
982 properly for vectors of objects. Do not assume that adding a
983 header size to a multiple of a word size yields a value that is
984 properly aligned for the whole union.
985 * lib/bitsetv.c (bitsetv_alloc): Likewise.
986
987 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
988 unique names for structures.
989 * lib/ebitset.c (ebitset_bytes): Likewise.
990 * lib/lbitset.c (lbitset_bytes): Likewise.
991
992 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
993 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
994 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
995 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
996 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
997 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
998 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
999 to improve the type-checking that GCC can do.
1000 * lib/bitset.c (bitset_op4_cmp): Likewise.
1001 * lib/bitset_stats.c (bitset_stats_count,
1002 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
1003 bitset_stats_copy, bitset_stats_disjoint_p,
1004 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
1005 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
1006 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
1007 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
1008 bitset_stats_and_or_cmp, bitset_stats_andn_or,
1009 bitset_stats_andn_or_cmp, bitset_stats_or_and,
1010 bitset_stats_or_and_cmp): Likewise.
1011 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
1012 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
1013 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
1014 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
1015
1016 * lib/abitset.h: Include bitset.h, not bbitset.h.
1017 * lib/ebitset.h: Likewise.
1018 * lib/lbitset.h: Likewise.
1019
1020 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
1021 All instances of parameters of type enum bitset_opts are now of
1022 type enum_bitset_opts, to conform to the C Standard, and similarly
1023 for enum_bitset_type.
1024 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
1025 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
1026
1027 Do not use "struct bitset_struct" to mean different things in
1028 different modules. Not only is this confusing, it violates
1029 the C Standard, which requires that structure types in different
1030 modules must be compatible if one is to be passed to the other.
1031 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
1032 All instances of "struct bitset_struct *" replaced with "bitset".
1033 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
1034 (union bitset_union, struct abitset_struct, struct ebitset_struct,
1035 struct lbitset_struct, struct bitset_stats_struct): New types.
1036 All uses of struct bitset_struct changed to union bitset_union,
1037 etc.
1038 * lib/abitset.c (struct abitset_struct, abitset,
1039 struct bitset_struct): Remove.
1040 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
1041 struct bitset_struct): Remove.
1042 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
1043 bitset_struct): Remove.
1044 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
1045 Likewise.
1046
1047 Do not call a function of type T using a call that assumes the
1048 function is of a different type U. Standard C requires that a
1049 function must be called with a type that is compatible with its
1050 definition.
1051 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
1052 New decls.
1053 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
1054 New functions.
1055 * lib/ebitset.c (PFV): Remove.
1056 * lib/lbitset.c (PFV): Likewise.
1057 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
1058 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
1059 decls.
1060 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
1061 (ebitset_vtable): Use them.
1062 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
1063 lbitset_xor): New functions.
1064 (lbitset_vtable): Use them.
1065
1066 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
1067 Declare.
1068
1069 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
1070 GCC warning.
1071 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
1072 Use offsetof, for simplicity.
1073
1074 2002-10-06 Paul Eggert <eggert@twinsun.com>
1075
1076 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
1077 the same width as int. This reapplies a hunk of the 2002-08-12 patch
1078 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
1079 which was inadvertently undone by the 2002-09-30 patch.
1080 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
1081 the same width as int.
1082
1083 2002-10-04 Paul Eggert <eggert@twinsun.com>
1084
1085 Version 1.50.
1086
1087 * configure.ac (AC_INIT), NEWS: Increment version number.
1088
1089 * doc/bison.texinfo: Minor spelling, grammar, and white space
1090 fixes.
1091 (Symbols): Mention that any negative value returned from yylex
1092 signifies end-of-input. Warn about negative chars. Mention
1093 the portable Standard C character set.
1094
1095 The GNU coding standard says CFLAGS and YFLAGS are reserved
1096 for the installer to set.
1097 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
1098 * src/Makefile.am (AM_CFLAGS): Likewise.
1099 (AM_YFLAGS): Renamed from YFLAGS.
1100
1101 Fix some MAX and MIN problems.
1102 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
1103 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
1104 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
1105 * src/reader.c (reader): Use it.
1106
1107 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
1108 POSIX 1003.1-2001 has removed fgrep.
1109
1110 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
1111
1112 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
1113 interpreted as signed.
1114 * lib/ebitset.c (ebitset_list): Fix bug.
1115
1116 2002-10-01 Paul Eggert <eggert@twinsun.com>

1121 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
1122 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
1123 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
1124 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
1125 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,

1139 Likewise.
1140 * lib/lbitset.c (lbitset_size, lbitset_list, lbitset_list_merge):
1141 Likewise.
1142
1143 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
1144 Use size_t, not unsigned int, to count bytes.
1145 * lib/abitset.h (abitset_bytes): Likewise.
1146 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
1147 Likewise.
1148 * lib/bitset.h (bitset_bytes): Likewise.
1149 * lib/bitset_stats.c (bitset_stats_bytes, bitset_stats_init): Likewise.

1161 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
1162 abitset_or_and, abitset_or_and_cmp):
1163 Use bitset_windex instead of unsigned int.
1164 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
1165 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
1166 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
1167 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):
1168 Likewise.
1169 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.

1179 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
1180 BITSET_SIZE_MAX): New macros.
1181 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
1182 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
1183 to BITSET_WINDEX_MAX.
1184
1185 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
1186 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
1187 since we now return the bitset_bindex type (not int).

1284
1285 2002-09-06 Paul Eggert <eggert@twinsun.com>
1286
1287 * doc/bison.texinfo (Conditions): Make explicit that the GPL
1288 exception applies only to yacc.c. This is a modification of a
1289 patch originally suggested by Akim Demaille.
1290
1291 2002-09-06 Akim Demaille <akim@epita.fr>
1292
1293 * data/c.m4 (b4_copyright): Move the GPL exception comment from
1294 here to...
1295 * data/yacc.c: here.
1296
1297 * data/lalr1.cc (struct yyltype): Don't define it, since we use
1298 LocationType.
1299 (b4_ltype): Default to yy::Location from location.hh.
1300
1301 2002-09-04 Jim Meyering <jim@meyering.net>
1302
1303 * data/yacc.c: Guard the declaration of yytoknum also with
1304 `#ifdef YYPRINT', so it is declared only when used.
1305
1306 2002-09-04 Akim Demaille <akim@epita.fr>
1307
1308 * configure.in: Rename as...

1315 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't
1316 translate maintainer only messages.
1317
1318 2002-08-12 Paul Eggert <eggert@twinsun.com>
1319

1336 (yyreportParseError): Use size_t for yysize.
1337 (yy_yypstack): No longer nested inside yypstates, as nested
1338 functions are not portable. Do not assume size_t is the
1339 same width as int.
1340 (yypstates): Do not assume that ptrdiff_t is the same width
1341 as int, and similarly for yyposn and YYINDEX.
1342
1343 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
1344
1345 * lib/Makefile.am (INCLUDES): Do not include from the intl
1346 directory, which has been removed.
1347 * src/Makefile.am (INCLUDES): Likewise.

1380 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
1381
1382 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
1383 PROTOTYPES to check for prototypes, and "defined __STDC__" to
1384 check for void *.
1385
1386 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
1387 size_t; the old version tried to do this but casted improperly.
1388 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
1389 (bitset_test): Now returns int, not unsigned long.
1390
1391 * lib/bitset_stats.c: Include "gettext.h".
1392 (_): New macro.
1393 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
1394 name locals "index", as it generates unnecessary warnings on some
1395 hosts that have an "index" function.
1396
1397 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
1398 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

1412 glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
1413 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.

1419 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
1420 lib/timevar.c.
1421 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
1422 manual recommends.
1423 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
1424
1425 * src/complain.c (strerror_r): Remove decl; not needed.
1426 (strerror): Use same pattern as ../lib/error.c.
1427
1428 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
1429
1430 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
1431
1432 * src/main.c (main): Cast result of bindtextdomain and textdomain
1433 to void, to avoid a GCC warning when --disable-nls is in effect.
1434
1435 * src/scan-gram.l: Use strings rather than escapes when possible,
1436 to minimize the number of warnings from xgettext.
1437 (handle_action_dollar, handle_action_at): Don't use isdigit,
1438 as it mishandles negative chars and it may not work as expected
1439 outside the C locale.
1440
1441 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
1442 this is a GCC extension and is not portable to other compilers.
1443
1444 * src/system.h (alloca): Use same pattern as ../lib/error.c.
1445 Do not include <ctype.h>; no longer needed.
1446 Do not include <malloc.h>; no longer needed (and generates
1447 warnings on OpenBSD 3.0).
1448
1449 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
1450 it's not portable.
1451
1452 * tests/regression.at: Do not use 'cc -c input.c -o input';
1453 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
1454
1455 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
1456 exit status as failure, not just exit status 1. Sun C exits
1457 with status 2 sometimes.
1458
1459 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
1460 Use it for the two large tests.
1461
1462 2002-08-02 Akim Demaille <akim@epita.fr>
1463
1464 * src/conflicts.c (conflicts_output): Don't output rules never
1465 reduced here, since anyway that computation doesn't work.
1466 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
1467 (rule_useless_p, rule_never_reduced_p): New.
1468 (grammar_rules_partial_print): Use a filter instead of a range.
1469 Display the title only if needed.
1470 (grammar_rules_print): Adjust.
1471 (grammar_rules_never_reduced_report): New.
1472 * src/tables.c (action_row): Move the computation of rules never
1473 reduced to...
1474 (token_actions): here.
1475 * src/main.c (main): Make the parser before making the report, so
1476 that rules never reduced are computed.
1477 Call grammar_rules_never_reduced_report.
1478 * src/print.c (print_results): Report rules never reduced.
1479 * tests/conflicts.at, tests/reduce.at: Adjust.
1480
1481 2002-08-01 Akim Demaille <akim@epita.fr>
1482
1483 Instead of attaching lookaheads and duplicating the rules being
1484 reduced by a state, attach the lookaheads to the reductions.
1485
1486 * src/state.h (state_t): Remove the `lookaheads',
1487 `lookaheads_rule' member.
1488 (reductions_t): Add a `lookaheads' member.
1489 Use a regular array for the `rules'.
1490 * src/state.c (reductions_new): Initialize the lookaheads member
1491 to 0.
1492 (state_rule_lookaheads_print): Adjust.
1493 * src/state.h, src/state.c (state_reductions_find): New.

1500 (initialize_LA): this.
1501 (lalr_free): Adjust.
1502 * src/main.c (main): Don't free nullable and derives too early: it
1503 is used by --verbose.
1504 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
1505
1506 2002-08-01 Akim Demaille <akim@epita.fr>

1512 Adjust all dependencies.
1513 * src/nullable.c (set_nullable, free_nullable): Rename as...
1514 (nullable_compute, nullable_free): these.
1515 (rule_list_t): Store rule_t *, not rule_number_t.
1516 * src/state.c (state_rule_lookaheads_print): Directly compare rule
1517 pointers, instead of their numbers.
1518 * src/main.c (main): Call nullable_free, and derives_free earlier,
1519 as they were lo longer used.
1520
1521 2002-08-01 Akim Demaille <akim@epita.fr>
1522
1523 * lib/timevar.c (get_time): Include children time.
1524 * src/lalr.h (LA, LArule): Don't export them: used with the
1525 state_t.
1526 * src/lalr.c (LA, LArule): Static.
1527 * src/lalr.h, src/lalr.c (lalr_free): New.
1528 * src/main.c (main): Call it.
1529 * src/tables.c (pack_vector): Check whether loc is >= to the
1530 table_size, not >.
1531 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
1532 (tables_generate): do it, since that's also it which allocates
1533 them.
1534 Don't free LA and LArule, main does.
1535
1536 2002-07-31 Akim Demaille <akim@epita.fr>
1537

1551 (goto_actions, sort_actions, matching_state, pack_vector)
1552 (table_ninf_remap, pack_table, prepare_actions): Move to...

1556 (output_check): Merge into...

1572 * src/getargs.h, src/getargs.c: Support trace_time for
1573 --trace=time.
1574 * src/main.c (stage): Remove.
1575 (main): Replace `stage' invocations with timevar calls.
1576 * src/output.c: Insert pertinent timevar calls.
1577
1578 2002-07-31 Akim Demaille <akim@epita.fr>
1579
1580 Let --trace have arguments.
1581
1582 * src/getargs.h (enum trace_e): New.
1583 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
1584 (long_options, short_options): --trace/-T takes an optional
1585 argument.
1586 Change all the uses of trace_flag to reflect the new flags.
1587 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
1588
1589 Strengthen `stage' portability.

1599
1600 In verbose parse error message, don't report `error' as an
1601 expected token.
1602 * tests/actions.at (Printers and Destructors): Adjust.
1603 * tests/calc.at (Calculator $1): Adjust.
1604 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
1605 error message, do not report the parser accepts the error token in
1606 that state.
1607
1608 2002-07-30 Akim Demaille <akim@epita.fr>
1609

1621 by conflicts.
1622
1623 * src/LR0.c (save_reductions): Don't make the final state too
1624 different: save its reduction (accept) instead of having a state
1625 without any action (no shift or goto, no reduce).
1626 Note: the final state is now a ``regular'' state, i.e., the
1627 parsers now contain `reduce 0' as default reduction.
1628 Nevertheless, since they decide to `accept' when yystate =
1629 final_state, they still will not reduce rule 0.
1630 * src/print.c (print_actions, print_reduction): Adjust.
1631 * src/output.c (action_row): Track reduced rules.
1632 (token_actions): Report rules never reduced.

1645
1646 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not

1653
1654 2002-07-29 Akim Demaille <akim@epita.fr>
1655
1656 Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
1657
1658 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
1659 (endtoken, accept): these.
1660 * src/reader.c (reader): Set endtoken's default tag to "$end".
1661 Set undeftoken's tag to "$undefined" instead of "$undefined.".
1662 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
1663 Adjust.
1664
1665 2002-07-29 Akim Demaille <akim@epita.fr>
1666
1667 * src/reduce.c (reduce_grammar): When the language is empty,
1668 complain about the start symbol, not the axiom.
1669 Use its location.
1670 * tests/reduce.at (Empty Language): New.
1671
1672 2002-07-26 Akim Demaille <akim@epita.fr>
1673
1674 * src/reader.h, src/reader.c (gram_error): ... can't get
1675 yycontrol without making too strong assumptions on the parser
1676 itself.
1677 * src/output.c (prepare_tokens): Use the real 0th value of
1678 token_translations instead of `0'.
1679 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1680 visible here.
1681 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1682 for the time being: %locations ought to provide it to yyerror.
1683
1684 2002-07-25 Akim Demaille <akim@epita.fr>
1685
1686 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
1687 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
1688 * tests/regression.at (Web2c Actions): Adjust.
1689
1690 2002-07-25 Akim Demaille <akim@epita.fr>
1691
1692 Stop storing rules from 1 to nrules + 1.

2846
2847 Remove `%thong' support as it is undocumented, unused, duplicates
2848 `%token's job, and creates useless e-mail traffic with people who

2850 duplicates `%token's job.

3010 the latter can be removed.
3011 (yy_token_number_type): Remove, only one use.

3226 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
3227 Note: this patch partially drops `semantic-parser' support: it
3228 always does `rule_length - n', where semantic parsers ought to
3229 always use `-n'.

3334 2002-04-22 Akim Demaille <akim@epita.fr>
3335
3336 * src/reader.c (token_translations_init): 256 is now the default
3337 value for the error token, i.e., it will be assigned another
3338 number if the user assigned 256 to one of her tokens.
3339 (reader): Don't force 256 to error.
3340 * doc/bison.texinfo (Symbols): Adjust.
3341 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
3342 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3

3347

3380
3381 2002-04-09 Akim Demaille <akim@epita.fr>
3382
3383 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
3384 full stderr, and strip it according to the bison options, instead
3385 of composing the error message from different bits.
3386 This makes it easier to check for several error messages.
3387 Adjust all the invocations.
3388 Add an invocation exercising the error token.
3389 Add an invocation demonstrating a stupid error message.
3390 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

3401 * src/symtab.h: here.
3402 (state_t.number): Is a token_number_t.
3403 * src/print.c, src/reader.c: Use undeftoken->number instead of
3404 hard coded 2.
3405 (Even though this 2 is not the same as above: the number of the
3406 undeftoken remains being 2, it is its user token number which
3407 might not be 2).
3408 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
3409 `user_token_number_max'.
3410 Output `undef_token_number'.
3411 * data/bison.simple, data/bison.c++: Use them.
3412 Be sure to map invalid yylex return values to
3413 `undef_token_number'. This saves us from gratuitous SEGV.

3430
3431 * src/gram.h (item_number_t): New, the type of item numbers in
3432 RITEM. Note that it must be able to code symbol numbers as
3433 positive number, and the negation of rule numbers as negative
3434 numbers.
3435 Adjust all dependencies (pretty many).
3436 * src/reduce.c (rule): Remove this `short *' pointer: use
3437 item_number_t.
3438 * src/system.h (MINSHORT, MAXSHORT): Remove.
3439 Include `limits.h'.
3440 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

3889 * src/warshall.h, src/warshall.c: Now work on arrays of bitsets.
3890
3891 2002-03-04 Akim Demaille <akim@epita.fr>
3892
3893 * src/print.c: Convert to use bitset.h, not hand coded iterations
3894 over ints.
3895
3896 2002-03-04 Akim Demaille <akim@epita.fr>
3897
3898 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
3899
3900 2002-03-04 Akim Demaille <akim@epita.fr>
3901
3902 * src/closure.c (ruleset): Be a bitset.
3903 (rulesetsize): Remove.
3904
3905 2002-03-04 Akim Demaille <akim@epita.fr>
3906
3907 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,
3908 * lib/bitsetv.h, lib/ebitset.c, lib/ebitset.h, lib/lbitset.c,
3909 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
3910 * src/closure.c (fderives): Be an array of bitsets.
3911
3912 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
3913
3914 * data/bison.c++: Merge the two generated headers. Insert a copyright
3915 notice in each output file.
3916
3917 2002-02-28 Akim Demaille <akim@epita.fr>
3918
3919 * data/bison.c++: Copy the prologue of bison.simple to fetch
3920 useful M4 definitions, such as b4_header_guard.
3921
3922 2002-02-25 Akim Demaille <akim@epita.fr>
3923
3924 * src/getargs.c (version): Give the name of the authors, and use a
3925 translator friendly scheme for the bgr
3926 copyright notice.
3927
3928 2002-02-25 Akim Demaille <akim@epita.fr>
3929
3930 * src/output.c (header_output): Remove, now handled completely via
3931 M4.
3932
3933 2002-02-25 Akim Demaille <akim@epita.fr>
3934
3935 * m4/m4.m4: New, from CVS Autoconf.
3936 * configure.in: Invoke it.
3937 * src/output.c (output_skeleton): Use its result instead of the
3938 hard coded name.
3939
3940 2002-02-25 Akim Demaille <akim@epita.fr>
3941
3942 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
3943 Fileutils 4.1.5.
3944 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
3945 * src/output.c (output_skeleton): Use mkstemp to create a real
3946 temporary file.
3947 Move the filling of `skeleton' and its muscle to...
3948 (prepare): here.
3949 (output): Move the definition of the prologue muscle to...
3950 (prepare): here.
3951 * src/system.h (DEFAULT_TMPDIR): New.
3952
3953 2002-02-14 Paul Eggert <eggert@twinsun.com>
3954
3955 Remove the support for C++ namespace cleanliness; it was
3956 causing more problems than it was curing, since it didn't work
3957 properly on some nonstandard C++ compilers. This can wait
3958 for a proper C++ parser.
3959
3960 * NEWS: Document this.
3961 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
3962 of C++, as it's treated like C now.
3963 * src/bison.simple (YYSTD): Remove.
3964 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
3965 Treat C++ just like Standard C instead of trying to support
3966 namespace cleanliness.
3967
3968 2002-02-14 Akim Demaille <akim@epita.fr>
3969
3970 * tests/regression.at (else): Adjust to Andreas' change.
3971
3972 2002-02-14 Akim Demaille <akim@epita.fr>
3973
3974 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
3975
3976 2002-02-13 Andreas Schwab <schwab@suse.de>
3977
3978 * src/output.c (output_rule_data): Don't output NULL, it might
3979 not be defined yet.
3980
3981 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
3982
3983 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
3984 (Copyright notice): Update.
3985
3986 2002-02-11 Akim Demaille <akim@epita.fr>
3987
3988 * tests/regression.at (%nonassoc and eof): Don't include
3989 nonportable headers.
3990
3991 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
3992
3993 * data/bison.c++: Correct error recovery. Make the user able to
3994 initialize the starting location.
3995
3996 2002-02-07 Akim Demaille <akim@epita.fr>
3997
3998 * tests/input.at: New.
3999
4000 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
4001
4002 * data/bison.c++: Replace some direct m4 expansions by constants. Be
4003 more consistent when naming methods and variables. Put preprocessor
4004 directives around tables only needed for debugging.
4005
4006 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
4007
4008 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
4009 C++ parsers.
4010 (yy::b4_name::parse): Use print_.
4011
4012 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
4013
4014 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
4015
4016 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
4017
4018 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
4019 C++ parsers.
4020 (yy::b4_name::parse): Build verbose error messages, and use error_.
4021
4022 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
4023
4024 * data/bison.c++: Fix m4 quoting in comments.
4025
4026 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
4027
4028 * data/bison.c++: Adjust the parser code. Fix some muscles that were
4029 not expanded by m4.
4030
4031 2002-02-05 Akim Demaille <akim@epita.fr>
4032
4033 * data/bison.c++: Adjust to the M4 back end.
4034 More is certainly needed.
4035
4036 2002-02-05 Akim Demaille <akim@epita.fr>
4037
4038 Give a try to M4 as a back end.
4039
4040 * lib/readpipe.c: New, from wdiff.
4041 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
4042 BISON_HAIRY.
4043 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
4044 specific values. Now it is m4 that performs the lookup.
4045 * src/parse-skel.y: Remove.
4046 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
4047 * src/output.c (actions_output, guards_output)
4048 (token_definitions_output): No longer keeps track of the output
4049 line number, hence remove the second argument.
4050 (guards_output): Check against the guard member of a rule, not the
4051 action member.
4052 Adjust callers.
4053 (output_skeleton): Don't look for the skeleton location, let m4 do
4054 that.
4055 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
4056 file will be used.
4057 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
4058 (prepare): Given that for the time being changesyntax is not
4059 usable in M4, rename the muscles using `-' to `_'.
4060 Define `defines_flag', `output_parser_name' and `output_header_name'.
4061 * src/output.h (actions_output, guards_output)
4062 (token_definitions_output): Adjust prototypes.
4063 * src/scan-skel.l: Instead of scanning the skeletons, it now
4064 processes the output of m4: `__oline__' and `#output'.
4065 * data/bison.simple: Adjust to be used by M4(sugar).
4066 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
4067 to date.
4068 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
4069 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
4070 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
4071 shamelessly stolen from CVS Autoconf.
4072
4073 2002-02-05 Akim Demaille <akim@epita.fr>
4074
4075 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
4076 * configure.in: Check for the declarations of free and malloc.
4077 * src/muscle_tab.c: Adjust.
4078
4079 2002-02-05 Akim Demaille <akim@epita.fr>
4080
4081 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
4082 which have no values.
4083
4084 2002-02-05 Akim Demaille <akim@epita.fr>
4085
4086 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
4087 * data/: here.
4088
4089 2002-01-29 Paul Eggert <eggert@twinsun.com>
4090
4091 * src/bison.simple (YYSIZE_T): Do not define merely because
4092 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
4093 On some platforms, <alloca.h> does not declare YYSTD (size_t).
4094
4095 2002-01-27 Akim Demaille <akim@epita.fr>
4096
4097 Fix `%nonassoc and eof'.
4098
4099 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
4100 which were not properly copied! Replace
4101 memcpy (res->errs, src->errs, src->nerrs);
4102 with
4103 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
4104 !!!
4105 * tests/regression.at (%nonassoc and eof): Adjust to newest
4106 Autotest: `.' is not in the PATH.
4107
4108 2002-01-27 Akim Demaille <akim@epita.fr>
4109
4110 * tests/sets.at (AT_EXTRACT_SETS): New.
4111 (Nullable): Use it.
4112 (Firsts): New.
4113
4114 2002-01-26 Akim Demaille <akim@epita.fr>
4115
4116 * tests/actions.at, tests/calc.at, tests/headers.at,
4117 * tests/torture.at: Adjust to the newest Autotest which no longer
4118 forces `.' in the PATH.
4119
4120 2002-01-25 Akim Demaille <akim@epita.fr>
4121
4122 * tests/regression.at (%nonassoc and eof): New.
4123 Suggested by Robert Anisko.
4124
4125 2002-01-24 Akim Demaille <akim@epita.fr>
4126
4127 Bison dumps core when trying to complain about broken input files.
4128 Reported by Cris van Pelt.
4129
4130 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
4131 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
4132 into...
4133 (Invalid inputs): Strengthen: exercise parse_percent_token.
4134
4135 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
4136
4137 * src/Makefile.am: Add bison.c++.
4138 * src/bison.c++: New skeleton.
4139
4140 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
4141
4142 * po/it.po: New.
4143
4144 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
4145
4146 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
4147
4148 2002-01-20 Marc Autret <marc@gnu.org>
4149
4150 * src/files.c (compute_output_file_names): Fix
4151
4152 2002-01-20 Marc Autret <marc@gnu.org>
4153
4154 * tests/output.at: New test.
4155 * src/files.c (compute_base_names): Don't map extensions when
4156 the YACC flag is set, use defaults.
4157 Reported by Evgeny Stambulchik.
4158
4159 2002-01-20 Marc Autret <marc@gnu.org>
4160
4161 * src/system.h: Need to define __attribute__ away for non-GCC
4162 compilers as well (i.e. the vendor C compiler).
4163 Suggested by Albert Chin-A-Young.
4164
4165 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
4166
4167 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
4168 canonical definition.
4169 * src/system.h: Use the canonical definition for PARAMS (avoids
4170 a conflict with the macro from lib/hash.h).
4171
4172 2002-01-11 Akim Demaille <akim@epita.fr>
4173
4174 * configure.in: Use AC_FUNC_STRNLEN.
4175 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
4176
4177 2002-01-09 Akim Demaille <akim@epita.fr>
4178
4179 * src/files.c, src/files.h (output_infix): New.
4180 (tab_extension): Remove.
4181 (compute_base_names): Compute the former, drop the latter.
4182 * src/output.c (prepare): Insert the muscles `output-infix', and
4183 `output-suffix'.
4184 * src/parse-skel.y (string, string.1): New.
4185 (section.header): Use it.
4186 (section.yacc): Remove.
4187 (prefix): Remove too.
4188 * src/scan-skel.l: Adjust.
4189 * src/bison.simple, src/bison.hairy: Adjust.
4190
4191 2002-01-09 Akim Demaille <akim@epita.fr>
4192
4193 * configure.in (WERROR_CFLAGS): Compute it.
4194 * src/Makefile.am (CFLAGS): Pass it.
4195 * tests/atlocal.in (CFLAGS): Idem.
4196 * src/files.c: Fix a few warnings.
4197 (get_extension_index): Remove, unused.
4198
4199 2002-01-08 Akim Demaille <akim@epita.fr>
4200
4201 * src/getargs.c (AS_FILE_NAME): New.
4202 (getargs): Use it to convert DOSish file names.
4203 * src/files.c (base_name): Rename as full_base_name to avoid
4204 clashes with `base_name ()'.
4205 (filename_split): New.
4206 (compute_base_names): N-th rewrite, using filename_split.
4207
4208 2002-01-08 Akim Demaille <akim@epita.fr>
4209
4210 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
4211 New, stolen from the Fileutils 4.1.
4212 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
4213 * configure.in: Check for the presence of memrchr, and of its
4214 prototype.
4215
4216 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
4217
4218 * lib/hash.h (__P): Added definition for this macro.
4219 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
4220 BUILT_SOURCES, to ensure they are generated first.
4221 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
4222 %error-verbose to allow bootstrapping with bison 1.30x.
4223
4224 2002-01-06 Akim Demaille <akim@epita.fr>
4225
4226 * src/reader.c (parse_braces): Don't fetch the next char, the
4227 convention is to fetch on entry.
4228 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
4229 'switch' without a following semicolon.
4230 * tests/regression.at (braces parsing): New.
4231
4232 2002-01-06 Akim Demaille <akim@epita.fr>
4233
4234 Bison is dead wrong in its RR conflict reports.
4235
4236 * tests/torture.at (GNU Cim Grammar): New.
4237 * src/conflicts.c (count_rr_conflicts): Fix.
4238
4239 2002-01-06 Akim Demaille <akim@epita.fr>
4240
4241 Creating package.m4 from configure.ac causes too many problems.
4242
4243 * tests/Makefile.am (package.m4): Create it by hand,
4244 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
4245
4246 2002-01-06 Akim Demaille <akim@epita.fr>
4247
4248 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
4249 skeleton.h.
4250
4251 2002-01-04 Paul Eggert <eggert@twinsun.com>
4252
4253 * doc/bison.texinfo (Debugging):
4254 Remove YYSTDERR; it's no longer defined or used.
4255 Also, s/cstdio.h/cstdio/.
4256
4257 2002-01-03 Akim Demaille <akim@epita.fr>
4258
4259 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
4260
4261 2002-01-03 Akim Demaille <akim@epita.fr>
4262
4263 * src/parse-skel.y (process_skeleton): Don't bind the parser's
4264 tracing code to --trace, wait for a better --trace option, with
4265 args.
4266
4267 2002-01-03 Akim Demaille <akim@epita.fr>
4268
4269 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
4270 The ISO C++ standard is extremely clear about it: stderr is
4271 considered a macro, not a regular symbol (see table 94 `Header
4272 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
4273 Therefore std:: does not apply to it. It still does with fprintf.
4274 Also, s/cstdio.h/cstdio/.
4275
4276 2002-01-03 Akim Demaille <akim@epita.fr>
4277
4278 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
4279 for non system headers.
4280
4281 2002-01-02 Akim Demaille <akim@epita.fr>
4282
4283 Equip the skeleton chain with location tracking, runtime trace,
4284 pure parser and scanner.
4285
4286 * src/parse-skel.y: Request a pure parser, locations, and prefix
4287 renaming.
4288 (%union): Having several members with the same type does not help
4289 type mismatches, simplify.
4290 (YYPRINT, yyprint): New.
4291 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
4292 (skel_error): this.
4293 Handle locations.
4294 * src/scan-skel.l: Adjust to these changes.
4295 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
4296 (LOCATION_PRINT, skel_control_t): New.
4297
4298 2001-12-30 Akim Demaille <akim@epita.fr>
4299
4300 * src/parse-skel.y: Get rid of the shift/reduce conflict:
4301 replace `gb' with BLANKS.
4302 * src/scan-skel.l: Adjust.
4303
4304 2001-12-30 Akim Demaille <akim@epita.fr>
4305
4306 * src/system.h: We don't need nor want bcopy.
4307 Throw away MS-DOS crap: we don't need getpid.
4308 * configure.in: We don't need strndup. It was even causing
4309 problems: because Flex includes the headers *before* us,
4310 _GNU_SOURCE is not defined by config.h, and therefore strndup was
4311 not visible.
4312 * lib/xstrndup.c: New.
4313 * src/scan-skel.l: Use it.
4314 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
4315 * src/parse-skel.y: Use %directives instead of #defines.
4316
4317 2001-12-30 Akim Demaille <akim@epita.fr>
4318
4319 * src/skeleton.h: New.
4320 * src/output.c (output_parser, output_master_parser): Remove, dead
4321 code.
4322 * src/output.h (get_lines_number, actions_output, guards_output)
4323 (token_definitions_output): Prototype them.
4324 * src/parse-skel.y: Add the license notice.
4325 Include output.h and skeleton.h.
4326 (process_skeleton): Returns void, and takes a single parameter.
4327 * src/scan-skel.l: Add the license notice.
4328 Include skeleton.h.
4329 Don't use %option yylineno: it seems that then Flex imagines
4330 REJECT has been used, and therefore it won't reallocate its
4331 buffers (which makes no other sense to me than a bug). It results
4332 in warnings for `unused: yy_flex_realloc'.
4333
4334 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
4335
4336 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4337 (MUSCLE_INSERT_PREFIX): ...to there.
4338 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4339 (MUSCLE_INSERT_PREFIX): Move from here...
4340
4341 * src/bison.hairy: Add a section directive. Put braces around muscle
4342 names. This parser skeleton is still broken, but Bison should not
4343 choke on a bad muscle 'syntax'.
4344 * src/bison.simple: Add a section directive. Put braces around muscle
4345 names.
4346
4347 * src/files.h (strsuffix, stringappend): Add declarations.
4348 (tab_extension): Add declaration.
4349 (short_base_name): Add declaration.
4350
4351 * src/files.c (strsuffix, stringappend): No longer static. These
4352 functions are used in the skeleton parser.
4353 (tab_extension): New.
4354 (compute_base_names): Use the computations done in this function
4355 to guess if the generated parsers should have '.tab' in their
4356 names.
4357 (short_base_name): No longer static.
4358
4359 * src/output.c (output_skeleton): New.
4360 (output): Disable call to output_master_parser, and give a try to
4361 a new skeleton handling system.
4362 (guards_output, actions_output): No longer static.
4363 (token_definitions_output, get_lines_number): No longer static.
4364
4365 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
4366
4367 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
4368 parse-skel.y.
4369
4370 * src/parse-skel.y: New file.
4371 * src/scan-skel.l: New file.
4372
4373 2001-12-29 Akim Demaille <akim@epita.fr>
4374
4375 %name-prefix is broken.
4376
4377 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
4378 Adjust all dependencies.
4379 * tests/headers.at (export YYLTYPE): Strengthen this test: use
4380 %name-prefix.
4381
4382 Renaming yylval but not yylloc is not consistent. Now we do.
4383
4384 * src/bison.simple: Prefix yylloc if used.
4385 * doc/bison.texinfo (Decl Summary): Document that.
4386
4387 2001-12-29 Akim Demaille <akim@epita.fr>
4388
4389 * doc/bison.texinfo: Promote `%long-directive' over
4390 `%long_directive'.
4391 Remove all references to fixed-output-files, yacc is enough.
4392
4393 2001-12-29 Akim Demaille <akim@epita.fr>
4394
4395 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4396 user prologue. These are defaults.
4397 * tests/actions.at (Mid-rule actions): Make sure the user can
4398 define YYDEBUG and YYERROR_VERBOSE.
4399
4400 2001-12-29 Akim Demaille <akim@epita.fr>
4401
4402 * src/output.c (header_output): Don't forget to export YYLTYPE and
4403 yylloc.
4404 * tests/headers.at (export YYLTYPE): New, make sure it does.
4405 * tests/regression.at (%union and --defines, Invalid CPP headers):
4406 Move to...
4407 * tests/headers.at: here.
4408
4409 2001-12-29 Akim Demaille <akim@epita.fr>
4410
4411 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
4412
4413 2001-12-29 Akim Demaille <akim@epita.fr>
4414
4415 * tests/actions.at (Mid-rule actions): Output on a single line
4416 instead of several.
4417
4418 2001-12-29 Akim Demaille <akim@epita.fr>
4419
4420 * doc/bison.texinfo: Formatting changes.
4421
4422 2001-12-29 Akim Demaille <akim@epita.fr>
4423
4424 Don't store the token defs in a muscle, just be ready to output it
4425 on command. Now possible via `symbols'. Fixes a memory leak.
4426
4427 * src/output.c (token_definitions_output): New.
4428 (output_parser, header_output): Use it.
4429 * src/reader.c (symbols_save): Remove.
4430
4431 2001-12-29 Akim Demaille <akim@epita.fr>
4432
4433 * src/bison.simple: Do not provide a default for YYSTYPE and
4434 YYLTYPE before the user's prologue. Otherwise it's hardly... a
4435 default.
4436
4437 2001-12-29 Akim Demaille <akim@epita.fr>
4438
4439 Mid-rule actions are simply... ignored!
4440
4441 * src/reader.c (readgram): Be sure to attach mid-rule actions to
4442 the empty-rule associated to the dummy symbol, not to the host
4443 rule.
4444 * tests/actions.at (Mid-rule actions): New.
4445
4446 2001-12-29 Akim Demaille <akim@epita.fr>
4447
4448 Memory leak.
4449
4450 * src/reader.c (reader): Free grammar.
4451
4452 2001-12-29 Akim Demaille <akim@epita.fr>
4453
4454 Memory leak.
4455
4456 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
4457 since it allocates it for each state, although only one is needed.
4458 (allocate_storage): Do it here.
4459
4460 2001-12-29 Akim Demaille <akim@epita.fr>
4461
4462 * src/options.h, src/options.c (create_long_option_table): Rename
4463 as...
4464 (long_option_table_new): this, with a clearer prototype.
4465 (percent_table): Remove, unused,
4466 * src/getargs.c (getargs): Adjust.
4467
4468 2001-12-29 Akim Demaille <akim@epita.fr>
4469
4470 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
4471 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
4472 as states.
4473
4474 2001-12-29 Akim Demaille <akim@epita.fr>
4475
4476 * src/lalr.c (build_relations): Rename `states' as `states1'.
4477 Sorry, I don't understand exactly what it is, no better name...
4478
4479 2001-12-29 Akim Demaille <akim@epita.fr>
4480
4481 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
4482 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
4483 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
4484 as rules.
4485
4486 2001-12-29 Akim Demaille <akim@epita.fr>
4487
4488 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
4489 ago.
4490
4491 2001-12-29 Akim Demaille <akim@epita.fr>
4492
4493 * src/reader.c, src/reader.h (user_toknums): Remove.
4494 Adjust all users to use symbols[i]->user_token_number.
4495
4496 2001-12-29 Akim Demaille <akim@epita.fr>
4497
4498 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
4499 Adjust all users to use symbols[i]->prec or ->assoc.
4500
4501 2001-12-29 Akim Demaille <akim@epita.fr>
4502
4503 * src/reader.c, src/reader.h (tags): Remove.
4504 Adjust all users to use symbols[i]->tag.
4505
4506 2001-12-29 Akim Demaille <akim@epita.fr>
4507
4508 * src/gram.h, src/gram.c (symbols): New, similar to state_table
4509 and rule_table.
4510 * src/reader.c (packsymbols): Fill this table.
4511 Drop sprec.
4512 * src/conflicts.c (resolve_sr_conflict): Adjust.
4513 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
4514 single table.
4515 Use symbols[i]->tag instead of tags[i].
4516
4517 2001-12-29 Akim Demaille <akim@epita.fr>
4518
4519 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
4520 In addition, put a comment in there, to replace...
4521 * tests/regression.at (%union and C comments): Remove.
4522
4523 2001-12-29 Akim Demaille <akim@epita.fr>
4524
4525 * tests/regression.at (Web2c Actions): Blindly move the actual
4526 output as expected output. The contents *seem* right to me, but I
4527 can't pretend reading perfectly parser tables... Nonetheless, all
4528 the other tests pass correctly, the table look OK, even though the
4529 presence of `$axiom' is to be noted: AFAICS it is useless (but
4530 harmless).
4531
4532 2001-12-29 Akim Demaille <akim@epita.fr>
4533
4534 * src/reader.c (readgram): Don't add the rule 0 if there were no
4535 rules read. In other words, add it _after_ having performed
4536 grammar sanity checks.
4537 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
4538
4539 2001-12-29 Akim Demaille <akim@epita.fr>
4540
4541 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
4542 visible, and some states have now a different number.
4543
4544 2001-12-29 Akim Demaille <akim@epita.fr>
4545
4546 * src/reader.c (readgram): Bind the initial rule's lineno to that
4547 of the first rule.
4548 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
4549 (Solved SR Conflicts): Adjust rule 0's line number.
4550
4551 2001-12-29 Akim Demaille <akim@epita.fr>
4552
4553 Fix the `GAWK Grammar' failure.
4554
4555 * src/LR0.c (final_state): Initialize to -1 so that we do compute
4556 the reductions of the first state which was mistakenly confused
4557 with the final state because precisely final_state was initialized
4558 to 0.
4559 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
4560 now noticed by Bison.
4561 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
4562 have a reduction on $default.
4563
4564 2001-12-29 Akim Demaille <akim@epita.fr>
4565
4566 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
4567 rule line numbers.
4568 * src/closure.c (print_closure): Likewise.
4569 * src/derives.c (print_derives): Likewise.
4570 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
4571 now.
4572
4573 2001-12-29 Akim Demaille <akim@epita.fr>
4574
4575 * src/lalr.c (lookaheads_print): New.
4576 (lalr): Call it when --trace-flag.
4577 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
4578 are dumped.
4579
4580 2001-12-29 Akim Demaille <akim@epita.fr>
4581
4582 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
4583 when walking through ritem, even via rule->rhs.
4584 * src/reduce.c (dump_grammar, useful_production, reduce_output)
4585 (useful_production, useless_nonterminals): Likewise.
4586 (reduce_grammar_tables): Likewise, plus update nritems.
4587 * src/nullable.c (set_nullable): Likewise.
4588 * src/lalr.c (build_relations): Likewise.
4589 * tests/sets.at (Nullable): Adjust.
4590 Fortunately, now, the $axiom is no longer nullable.
4591
4592 2001-12-29 Akim Demaille <akim@epita.fr>
4593
4594 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
4595 the 0-sentinel.
4596 * src/gram.c (ritem_longest_rhs): Likewise.
4597 * src/reduce.c (nonterminals_reduce): Likewise.
4598 * src/print_graph.c (print_graph): Likewise.
4599 * src/output.c (output_rule_data): Likewise.
4600 * src/nullable.c (set_nullable): Likewise.
4601
4602 2001-12-29 Akim Demaille <akim@epita.fr>
4603
4604 * src/output.c: Comment changes.
4605
4606 2001-12-27 Paul Eggert <eggert@twinsun.com>
4607
4608 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
4609 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
4610 Sparc, as they were causing more porting problems than the
4611 (minor) performance improvement was worth.
4612
4613 Also, catch up with 1.31's YYSTD.
4614
4615 2001-12-27 Akim Demaille <akim@epita.fr>
4616
4617 * src/output.c (output_gram): Rely on nritems, not the
4618 0-sentinel. See below.
4619 Use -1 as separator, not 0.
4620 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
4621 Rely on -1 as separator in yyrhs, instead of 0.
4622 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
4623 twice `Now at end of input', therefore there are two lines less to
4624 expect.
4625
4626 2001-12-27 Akim Demaille <akim@epita.fr>
4627
4628 * tests/regression.at (Unresolved SR Conflicts):
4629 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
4630 below.
4631
4632 2001-12-27 Akim Demaille <akim@epita.fr>
4633
4634 * src/LR0.c (new_state): Recognize the final state by the fact it
4635 is reached by eoftoken.
4636 (insert_start_shifting_state, insert_eof_shifting_state)
4637 (insert_accepting_state, augment_automaton): Remove, since now
4638 these states are automatically computed from the initial state.
4639 (generate_states): Adjust.
4640 * src/print.c: When reporting a rule number to the user, substract
4641 1, so that the axiom rule is rule 0, and the first user rule is 1.
4642 * src/reduce.c: Likewise.
4643 * src/print_graph.c (print_core): For the time being, just as for
4644 the report, depend upon --trace-flags to dump the full set of
4645 items.
4646 * src/reader.c (readgram): Once the grammar read, insert the rule
4647 0: `$axiom: START-SYMBOL $'.
4648 * tests/set.at: Adjust: rule 0 is now displayed, and since the
4649 number of the states has changed (the final state is no longer
4650 necessarily the last), catch up.
4651
4652 2001-12-27 Akim Demaille <akim@epita.fr>
4653
4654 Try to make the use of the eoftoken valid. Given that its value
4655 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
4656 is used instead of > 0 where appropriate, (ii), depend upon nritems
4657 instead of the 0-sentinel.
4658
4659 * src/gram.h, src/gram.c (nritems): New.
4660 Expected to be duplication of nitems, but for the time being...
4661 * src/reader.c (packgram): Assert nritems and nitems are equal.
4662 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
4663 * src/closure.c (print_closure, print_fderives): Likewise.
4664 * src/gram.c (ritem_print): Likewise.
4665 * src/print.c (print_core, print_grammar): Likewise.
4666 * src/print_graph.c: Likewise.
4667
4668 2001-12-27 Akim Demaille <akim@epita.fr>
4669
4670 * src/main.c (main): If there are complains after grammar
4671 reductions, then output the report anyway if requested, then die.
4672 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
4673 * src/reader.c (eoftoken): New.
4674 (parse_token_decl): If the token being defined has value `0', it
4675 is the eoftoken.
4676 (packsymbols): No longer hack `tags' to insert `$' by hand.
4677 Be sure to preserve the value of the eoftoken.
4678 (reader): Make sure eoftoken is defined.
4679 Initialize nsyms to 0: now eoftoken is created just like the others.
4680 * src/print.c (print_grammar): Don't special case the eof token.
4681 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
4682 lie anyway, albeit pleasant.
4683 * tests/calc.at: Exercise error messages with eoftoken.
4684 Change the grammar so that empty input is invalid.
4685 Adjust expectations.
4686 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
4687
4688 2001-12-27 Akim Demaille <akim@epita.fr>
4689
4690 * configure.in: Check the protos of strchr ans strspn.
4691 Replace strchr if needed.
4692 * src/system.h: Provide the protos of strchr, strspn and memchr if
4693 missing.
4694 * lib/strchr.c: New.
4695 * src/reader.c (symbols_save): Use strchr.
4696
4697 2001-12-27 Akim Demaille <akim@epita.fr>
4698
4699 * src/print.c, src/print_graph.c (escape): New.
4700 Use it to quote the TAGS outputs.
4701 * src/print_graph.c (print_state): Now errors are in red, and
4702 reductions in green.
4703 Prefer high to wide: output the state number on a line of its own.
4704
4705 2001-12-27 Akim Demaille <akim@epita.fr>
4706
4707 * src/state.h, src/state.c (reductions_new): New.
4708 * src/LR0.c (set_state_table): Let all the states have a
4709 `reductions', even if reduced to 0.
4710 (save_reductions): Adjust.
4711 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4712 * src/print.c (print_reductions, print_actions): Adjust.
4713 * src/output.c (action_row): Adjust.
4714
4715 2001-12-27 Akim Demaille <akim@epita.fr>
4716
4717 * src/state.h, src/state.c (errs_new, errs_dup): New.
4718 * src/LR0.c (set_state_table): Let all the states have an errs,
4719 even if reduced to 0.
4720 * src/print.c (print_errs, print_reductions): Adjust.
4721 * src/output.c (output_actions, action_row): Adjust.
4722 * src/conflicts.c (resolve_sr_conflict): Adjust.
4723
4724 2001-12-27 Akim Demaille <akim@epita.fr>
4725
4726 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
4727
4728 2001-12-27 Akim Demaille <akim@epita.fr>
4729
4730 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
4731 * src/print.c: here.
4732 (lookaheadset, shiftset): New, used as additional storage by
4733 print_reductions.
4734 (print_results): Adjust.
4735 (print_shifts, print_gotos, print_errs): New, extracted from...
4736 (print_actions): here.
4737 * src/print_graph.c (print_actions): Remove dead code.
4738
4739 2001-12-27 Akim Demaille <akim@epita.fr>
4740
4741 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
4742 `$n' and `@n'.
4743
4744 2001-12-27 Akim Demaille <akim@epita.fr>
4745
4746 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
4747 (build_relations): Adjust.
4748
4749 2001-12-27 Akim Demaille <akim@epita.fr>
4750
4751 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
4752 duplication.
4753
4754 2001-12-27 Akim Demaille <akim@epita.fr>
4755
4756 * src/reader.c (packgram): Catch nitems overflows.
4757
4758 2001-12-27 Akim Demaille <akim@epita.fr>
4759
4760 * src/files.c, src/files.h (guard_obstack): Remove.
4761 * src/output.c (output): Adjust.
4762 * src/reader.c (parse_braces): New, factoring...
4763 (copy_action, copy_guard): these two which are renamed as...
4764 (parse_action, parse_guard): these.
4765 As a voluntary consequence, using braces around guards is now
4766 mandatory.
4767
4768 2001-12-27 Akim Demaille <akim@epita.fr>
4769
4770 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
4771 * src/reader.c (symbol_list): `guard' and `guard_line' are new
4772 members.
4773 (symbol_list_new): Adjust.
4774 (copy_action): action_line is the first line, not the last.
4775 (copy_guard): Just as for actions, store the `action' only, not
4776 the switch/case/break flesh.
4777 Don't parse the user action that might follow the guard, let...
4778 (readgram): do it, i.e., now, there can be an action after a
4779 guard.
4780 In other words the guard is just explicitly optional.
4781 (packgram): Adjust.
4782 * src/output.c (guards_output): New.
4783 (output_parser): Call it when needed.
4784 (output): Also free the guard and attrs obstacks.
4785 * src/files.c, src/files.h (obstack_save): Remove.
4786 (output_files): Remove.
4787 As a result, if one needs the former `.act' file, using an
4788 appropriate skeleton which requires actions and guards is now
4789 required.
4790 * src/main.c (main): Adjust.
4791 * tests/semantic.at: New.
4792 * tests/regression.at: Use `input.y' as input file name.
4793 Avoid 8+3 problems by requiring input.c when the test needs the
4794 parser.
4795
4796 2001-12-27 Akim Demaille <akim@epita.fr>
4797
4798 * src/reader.c (symbol_list_new): Be sure to initialize all the
4799 fields.
4800
4801 2001-12-27 Akim Demaille <akim@epita.fr>
4802
4803 All the hacks using a final pseudo state are now useless.
4804
4805 * src/LR0.c (set_state_table): state_table holds exactly nstates.
4806 * src/lalr.c (nLA): New.
4807 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4808 instead of lookaheadsp from the pseudo state (nstate + 1).
4809
4810 2001-12-27 Akim Demaille <akim@epita.fr>
4811
4812 * src/output.c (action_row, token_actions): Use a state_t instead
4813 of a integer, and nlookaheads instead of the following state's
4814 lookaheadsp.
4815
4816 2001-12-27 Akim Demaille <akim@epita.fr>
4817
4818 * src/conflicts.c (log_resolution, flush_shift)
4819 (resolve_sr_conflict, set_conflicts, solve_conflicts)
4820 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4821 (conflicts_print, print_reductions): Use a state_t instead of an
4822 integer when referring to a state.
4823 As much as possible, depend upon nlookaheads, instead of the
4824 `lookaheadsp' member of the following state (since lookaheads of
4825 successive states are successive, the difference between state n + 1
4826 and n served as the number of lookaheads for state n).
4827 * src/lalr.c (add_lookback_edge): Likewise.
4828 * src/print.c (print_core, print_actions, print_state)
4829 (print_results): Likewise.
4830 * src/print_graph.c (print_core, print_actions, print_state)
4831 (print_graph): Likewise.
4832 * src/conflicts.h: Adjust.
4833
4834 2001-12-27 Akim Demaille <akim@epita.fr>
4835
4836 * src/bison.hairy: Formatting/comment changes.
4837 ANSIfy.
4838 Remove `register' indications.
4839 Add plenty of `static'.
4840
4841 2001-12-27 Akim Demaille <akim@epita.fr>
4842
4843 * src/output.c (prepare): Drop the muscle `ntbase' which
4844 duplicates ntokens.
4845 * src/bison.simple: Formatting/comment changes.
4846 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4847 is an undocumented synonym.
4848
4849 2001-12-22 Akim Demaille <akim@epita.fr>
4850
4851 * src/output.c (output_table_data): Change the prototype to use
4852 `int' for array ranges: some invocations do pass an int, not a
4853 short.
4854 Reported by Wayne Green.
4855
4856 2001-12-22 Akim Demaille <akim@epita.fr>
4857
4858 Some actions of web2c.y are improperly triggered.
4859 Reported by Mike Castle.
4860
4861 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4862 * tests/regression.at (Web2c): Rename as...
4863 (Web2c Report): this.
4864 (Web2c Actions): New.
4865
4866 2001-12-22 Akim Demaille <akim@epita.fr>
4867
4868 Reductions in web2c.y are improperly reported.
4869 Reported by Mike Castle.
4870
4871 * src/conflicts.c (print_reductions): Fix.
4872 * tests/regression.at (Web2c): New.
4873
4874 2001-12-18 Akim Demaille <akim@epita.fr>
4875
4876 Some host fail on `assert (!"foo")', which expands to
4877 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4878 Reported by Nelson Beebee.
4879
4880 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4881 `#define it_succeeded 0' and `assert (it_succeeded)'.
4882
4883 2001-12-17 Marc Autret <autret_m@epita.fr>
4884
4885 * src/bison.simple: Don't hard code the skeleton line and filename.
4886 * src/output.c (output_parser): Rename 'line' as 'output_line'.
4887 New line counter 'skeleton_line' (skeleton-line muscle).
4888
4889 2001-12-17 Paul Eggert <eggert@twinsun.com>
4890
4891 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4892 YYDEBUG must be defined to a nonzero value.
4893
4894 * src/bison.simple (yytname): Do not assume that the user defines
4895 YYDEBUG to a properly parenthesized expression.
4896
4897 2001-12-17 Akim Demaille <akim@epita.fr>
4898
4899 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4900 nlookaheads is a new member.
4901 Adjust all users.
4902 * src/lalr.h (nlookaheads): Remove this orphan declaration.
4903 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4904 state.
4905
4906 2001-12-17 Akim Demaille <akim@epita.fr>
4907
4908 * src/files.h, src/files.c (open_files, close_files): Remove.
4909 * src/main.c (main): Don't open/close files, nor invoke lex_free,
4910 let...
4911 * src/reader.c (reader): Do it.
4912
4913 2001-12-17 Akim Demaille <akim@epita.fr>
4914
4915 * src/conflicts.c (print_reductions): Formatting changes.
4916
4917 2001-12-17 Akim Demaille <akim@epita.fr>
4918
4919 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
4920 (flush_reduce): New.
4921 (resolve_sr_conflict): Adjust.
4922
4923 2001-12-17 Akim Demaille <akim@epita.fr>
4924
4925 * src/output.c (output_obstack): Be static and rename as...
4926 (format_obstack): this, to avoid any confusion with files.c's
4927 output_obstack.
4928 * src/reader.h (muscle_obstack): Move to...
4929 * src/output.h: here, since it's defined in output.c.
4930
4931 2001-12-17 Akim Demaille <akim@epita.fr>
4932
4933 * src/output.c (action_row, save_column, default_goto)
4934 (sort_actions, matching_state, pack_vector): Better variable
4935 locality.
4936
4937 2001-12-17 Akim Demaille <akim@epita.fr>
4938
4939 * src/output.c: Various formatting changes.
4940
4941 2001-12-17 Akim Demaille <akim@epita.fr>
4942
4943 * src/files.c (output_files): Free the output_obstack.
4944 * src/main.c (main): Call print and print_graph conditionally.
4945 * src/print.c (print): Work unconditionally.
4946 * src/print_graph.c (print_graph): Work unconditionally.
4947 * src/conflicts.c (log_resolution): Output only if verbose_flag.
4948
4949 2001-12-16 Marc Autret <autret_m@epita.fr>
4950
4951 * src/output.c (actions_output): Fix. When we use %no-lines,
4952 there is one less line per action.
4953
4954 2001-12-16 Marc Autret <autret_m@epita.fr>
4955
4956 * src/bison.simple: Remove a useless #line directive.
4957 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4958 * src/output.c (get_lines_number): New.
4959 (output_parser): Adjust, now takes care about the lines of a
4960 output muscles.
4961 Fix line numbering.
4962 (actions_output): Computes the number of lines taken by actions.
4963 (output_master_parser): Insert new skeleton which is the name of
4964 the output parser file name.
4965
4966 2001-12-15 Marc Autret <autret_m@epita.fr>
4967
4968 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
4969
4970 2001-12-15 Marc Autret <autret_m@epita.fr>
4971
4972 * src/output.c (output_gram): Keep track of the hairy one.
4973
4974 2001-12-15 Akim Demaille <akim@epita.fr>
4975
4976 Make `make distcheck' work.
4977
4978 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4979 system.h which uses libgettext.h.
4980
4981 2001-12-15 Akim Demaille <akim@epita.fr>
4982
4983 * src/nullable.c (set_nullable): Useless rules must be skipped,
4984 otherwise, since we range over their symbols, we might look at a
4985 nonterminal which no longer ``exists'', i.e., it is not counted in
4986 `nvars', hence we overflow our arrays.
4987
4988 2001-12-15 Akim Demaille <akim@epita.fr>
4989
4990 The header can also be produced directly, without any obstack!
4991 Yahoo!
4992
4993 * src/files.c, src/files.h (defines_obstack): Remove.
4994 (compute_header_macro): Global.
4995 (defines_obstack_save): Remove.
4996 * src/reader.c (parse_union_decl): No longer output to
4997 defines_obstack: its content can be found in the `stype' muscle
4998 anyway.
4999 (output_token_translations): Merge into...
5000 (symbols_output): this.
5001 Rename as...
5002 (symbols_save): this.
5003 (reader): Adjust.
5004 * src/output.c (header_output): New.
5005 (output): Call it.
5006
5007 2001-12-15 Akim Demaille <akim@epita.fr>
5008
5009 * src/reader.c (parse_union_decl): Instead of handling two obstack
5010 simultaneously, use one to define the `stype' muscle, and use the
5011 value of the latter to fill defines_obstack.
5012 (copy_comment): Remove.
5013 (copy_comment2): Work for a single obstack.
5014 Rename as...
5015 (copy_comment): this.
5016
5017 2001-12-15 Akim Demaille <akim@epita.fr>
5018
5019 * src/lex.c, src/lex.h (xgetc): No longer static.
5020 * src/reader.c (parse_union_decl): Revamp.
5021
5022 2001-12-15 Akim Demaille <akim@epita.fr>
5023
5024 Still making progress in separating Bison into (i) input, (ii)
5025 process, (iii) output: now we can directly output the parser file
5026 without using table_obstack at all.
5027
5028 * src/files.c, src/files.h (table_obstack): Bye bye.
5029 (parser_file_name): New.
5030 * src/files.c (compute_output_file_names): Compute it.
5031 * src/output.c (actions_output, output_parser)
5032 (output_master_parser): To a file instead of an obstack.
5033
5034 2001-12-15 Akim Demaille <akim@epita.fr>
5035
5036 Attach actions to rules, instead of pre-outputting them to
5037 actions_obstack.
5038
5039 * src/gram.h (rule_t): action and action_line are new members.
5040 * src/reader.c (symbol_list): Likewise.
5041 (copy_action): Save the actions within the rule.
5042 (packgram): Save them in rule_table.
5043 * src/output.c (actions_output): New.
5044 (output_parser): Use it on `%%actions'.
5045 (output_rule_data): Don't free rule_table.
5046 (output): Do it.
5047 (prepare): Don't save the `action' muscle.
5048 * src/bison.simple: s/%%action/%%actions/.
5049
5050 2001-12-15 Akim Demaille <akim@epita.fr>
5051
5052 * src/reader.c (copy_action): When --yacc, don't append a `;'
5053 to the user action: let it fail if lacking.
5054 Suggested by Arnold Robbins and Tom Tromey.
5055
5056 2001-12-14 Akim Demaille <akim@epita.fr>
5057
5058 * src/lex.c (literalchar): Simply return the char you decoded, non
5059 longer mess around with obstacks and int pointers.
5060 Adjust all callers.
5061
5062 2001-12-14 Akim Demaille <akim@epita.fr>
5063
5064 * src/lex.c (literalchar): Don't escape the special characters,
5065 just decode them, and keep them as char (before, eol was output as
5066 the 2 char string `\n' etc.).
5067 * src/output.c (output_rule_data): Use quotearg to output the
5068 token strings.
5069
5070 2001-12-13 Paul Eggert <eggert@twinsun.com>
5071
5072 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
5073 Do not infringe on the global user namespace when using C++.
5074 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
5075 All uses of `fprintf' and `stderr' changed.
5076
5077 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
5078
5079 2001-12-13 Akim Demaille <akim@epita.fr>
5080
5081 The computation of nullable is broken: it doesn't handle empty
5082 RHS's properly.
5083
5084 * tests/torture.at (GNU AWK Grammar): New.
5085 * tests/sets.at (Nullable): New.
5086 * src/nullable.c (set_nullable): Instead of blindly looping over
5087 `ritems', loop over the rules, and then over their rhs's.
5088
5089 Work around Autotest bugs.
5090
5091 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
5092 frame, because Autotest understand lines starting with a `+' as
5093 traces from the shell. Then, they are not processed properly.
5094 Admittedly an Autotest bug, but we don't have time to wait for
5095 Autotest to catch up.
5096 * tests/regression.at (Broken Closure): Adjust to the new table
5097 frames.
5098 Move to...
5099 * tests/sets.at: here.
5100
5101 2001-12-13 Akim Demaille <akim@epita.fr>
5102
5103 * src/closure.c (closure): Use nrules instead of playing tricks
5104 with BITS_PER_WORD.
5105
5106 2001-12-13 Akim Demaille <akim@epita.fr>
5107
5108 * src/print.c (print_actions): Output the handling of `$' as the
5109 traces do: shifting the token EOF. Before EOF was treated as a
5110 nonterminal.
5111 * tests/regression.at: Adjust some tests.
5112 * src/print_graph.c (print_core): Complete the set of items via
5113 closure. The next-to-final and final states are still unsatisfying,
5114 but that's to be addressed elsewhere.
5115 No longer output the rule numbers, but do output the state number.
5116 A single loop for the shifts + gotos is enough, but picked a
5117 distinct color for each.
5118 (print_graph): Initialize and finalize closure.
5119
5120 2001-12-13 Akim Demaille <akim@epita.fr>
5121
5122 * src/reader.c (readgram): Remove dead code, an strip useless
5123 braces.
5124 (get_type): Remove, unused.
5125
5126 2001-12-12 Akim Demaille <akim@epita.fr>
5127
5128 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
5129 on that of lib/error.c.
5130
5131 2001-12-12 Akim Demaille <akim@epita.fr>
5132
5133 Some hosts don't like `/' in includes.
5134
5135 * src/system.h: Include libgettext.h without qualifying the path.
5136 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
5137 $(top_srcdir).
5138
5139 2001-12-11 Marc Autret <autret_m@epita.fr>
5140
5141 * src/output.c (output_parser): Remove useless muscle.
5142
5143 2001-12-11 Marc Autret <autret_m@epita.fr>
5144
5145 * src/bison.simple: Remove #line just before %%epilogue. It
5146 is now handled in ...
5147 * src/reader.c (read_additionnal_code): Add the output of a
5148 #line for the epilogue.
5149
5150 2001-12-10 Marc Autret <autret_m@epita.fr>
5151
5152 * src/reader.c (copy_definition): Re-use CPP-outed code which
5153 replace precedent remove.
5154 * src/bison.simple: Remove #line before %%prologue because
5155 %%input-line is wrong at this time.
5156
5157 2001-12-10 Marc Autret <autret_m@epita.fr>
5158
5159 * src/reader.c (symbols_output): Clean up.
5160 * src/output.c (output_gram, output): Clean up.
5161
5162 2001-12-10 Akim Demaille <akim@epita.fr>
5163
5164 * src/lalr.c (initialize_lookaheads): New. Extracted from...
5165 * src/LR0.c (set_state_table): here.
5166 * src/lalr.c (lalr): Call it.
5167
5168 2001-12-10 Akim Demaille <akim@epita.fr>
5169
5170 * src/state.h (shifts): Remove the `number' member: shifts are
5171 attached to state, hence no longer need to be labelled with a
5172 state number.
5173
5174 2001-12-10 Akim Demaille <akim@epita.fr>
5175
5176 Now that states have a complete set of members, the linked list of
5177 shifts is useless: just fill directly the state's shifts member.
5178
5179 * src/state.h (shifts): Remove the `next' member.
5180 * src/LR0.c (first_state, last_state): Remove.
5181 Adjust the callers.
5182 (augment_automaton): Don't look for the shifts that must be added
5183 a shift on EOF: it is those of the state we looked for! But now,
5184 since shifts are attached, it is no longer needed to looking
5185 merely by its id: its number.
5186
5187 2001-12-10 Akim Demaille <akim@epita.fr>
5188
5189 * src/LR0.c (augment_automaton): Better variable locality.
5190 Remove an impossible branch: if there is a state corresponding to
5191 the start symbol being shifted, then there is shift for the start
5192 symbol from the initial state.
5193
5194 2001-12-10 Akim Demaille <akim@epita.fr>
5195
5196 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
5197 only when appropriate: when insert_start_shifting_state' is not
5198 invoked.
5199 * tests/regression.at (Rule Line Numbers): Adjust.
5200
5201 2001-12-10 Akim Demaille <akim@epita.fr>
5202
5203 * src/LR0.c (augment_automaton): Now that all states have shifts,
5204 merge the two cases addition shifts to the initial state.
5205
5206 2001-12-10 Akim Demaille <akim@epita.fr>
5207
5208 * src/lalr.c (set_state_table): Move to...
5209 * src/LR0.c: here.
5210 * src/lalr.c (lalr): Don't call it...
5211 * src/LR0.c (generate_states): do it.
5212 * src/LR0.h (first_state): Remove, only the table is used.
5213
5214 2001-12-10 Akim Demaille <akim@epita.fr>
5215
5216 * src/LR0.h (first_shift, first_reduction): Remove.
5217 * src/lalr.c: Don't use first_shift: find shifts through the
5218 states.
5219
5220 2001-12-10 Akim Demaille <akim@epita.fr>
5221
5222 * src/LR0.c: Attach shifts to states as soon as they are
5223 computed.
5224 * src/lalr.c (set_state_table): Instead of assigning shifts to
5225 state, just assert that the mapping was properly done.
5226
5227 2001-12-10 Akim Demaille <akim@epita.fr>
5228
5229 * src/LR0.c (insert_start_shift): Rename as...
5230 (insert_start_shifting_state): this.
5231 (insert_eof_shifting_state, insert_accepting_state): New.
5232 (augment_automaton): Adjust.
5233 Better locality of the variables.
5234 When looking if the start_symbol is shifted from the initial
5235 state, using `while (... symbol != start_symbol ...)' sounds
5236 better than `while (... symbol < start_symbol ...)': If fail
5237 to see how the order between symbols could be relevant!
5238
5239 2001-12-10 Akim Demaille <akim@epita.fr>
5240
5241 * src/getargs.h: Don't declare `spec_name_prefix' and
5242 `spec_file_prefix', declared by src/files.h.
5243 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
5244 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
5245 * src/output.c (prepare): Adjust.
5246 * src/reader.c (symbols_output): Likewise.
5247 * src/vmsgetargs.c: Vaguely adjust, but who cares?
5248
5249 2001-12-10 Akim Demaille <akim@epita.fr>
5250
5251 * src/muscle_tab.c (muscle_init): NULL is a better default than
5252 `"0"'.
5253
5254 2001-12-10 Akim Demaille <akim@epita.fr>
5255
5256 * src/reader.c (reader): Calling symbols_output once is enough.
5257
5258 2001-12-10 Akim Demaille <akim@epita.fr>
5259
5260 Now that states have a complete set of members, the linked list of
5261 reductions is useless: just fill directly the state's reductions
5262 member.
5263
5264 * src/state.h (struct reductions): Remove member `number' and
5265 `next'.
5266 * src/LR0.c (first_reduction, last_reduction): Remove.
5267 (save_reductions): Don't link the new reductions, store them in
5268 this_state.
5269 * src/lalr.c (set_state_table): No need to attach reductions to
5270 states, it's already done.
5271 * src/output.c (output_actions): No longer free the shifts, then
5272 the reductions, then the states: free all the states and their
5273 members.
5274
5275 2001-12-10 Akim Demaille <akim@epita.fr>
5276
5277 * src/options.c (OPTN, DRTV, BOTH): New.
5278 (option_table): Use them.
5279
5280 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
5281 the job of system.h.
5282 * src/options.c: Don't include stdio.h and xalloc.h for the same
5283 reasons.
5284
5285 2001-12-10 Akim Demaille <akim@epita.fr>
5286
5287 * src/output.c (output, prepare): Make sure the values of the
5288 muscles `action' and `prologue' are 0-terminated.
5289
5290 2001-12-10 Akim Demaille <akim@epita.fr>
5291
5292 Clean up GCC warnings.
5293
5294 * src/reader.c (copy_action): `buf' is not used.
5295 (parse_skel_decl): Be static.
5296 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
5297 * src/options.h (create_long_option_table): Have a real prototype.
5298 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
5299 (hash_delete_at): Return const void *.
5300 Adjust casts to preserve the const.
5301
5302 2001-12-10 Akim Demaille <akim@epita.fr>
5303
5304 * configure.in: Require 2.52g.
5305 M4 is not needed, but AUTOM4TE is.
5306 * m4/m4.m4: Remove.
5307 * tests/Makefile.am: Adjust.
5308
5309 2001-12-10 Akim Demaille <akim@epita.fr>
5310
5311 One structure for states is enough, even though theoretically
5312 there are LR(0) states and LALR(1) states.
5313
5314 * src/lalr.h (state_t): Remove.
5315 (state_table): Be state_t **, not state_t *.
5316 * src/state.h (core, CORE_ALLOC): Rename as...
5317 (state_t, STATE_ALLOC): this.
5318 Add the LALR(1) members: shifts, reductions, errs.
5319 * src/LR0.c (state_table): Rename as...
5320 (state_hash): this, to avoid name clashes with the global
5321 `state_table'.
5322 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
5323 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
5324
5325 2001-12-10 Akim Demaille <akim@epita.fr>
5326
5327 Bison dumps core on bash.y.
5328 Reported by Pascal Bart.
5329
5330 * src/warshall.c (bitmatrix_print): New.
5331 (TC): Use it.
5332 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
5333 j must be the outer loop.
5334 * tests/regression.at (Broken Closure): New.
5335
5336 2001-12-05 Akim Demaille <akim@epita.fr>
5337
5338 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
5339 its argument.
5340 Reported by Peter Hámorský.
5341
5342 2001-12-05 Akim Demaille <akim@epita.fr>
5343
5344 * src/conflicts.c (err_table): Remove.
5345 (resolve_sr_conflict): Adjust.
5346 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
5347 Rename as...
5348 (state_t.reductions, state_t.shifts): this.
5349
5350 2001-12-05 Akim Demaille <akim@epita.fr>
5351
5352 * src/reduce.c (reduce_grammar_tables): No longer disable the
5353 removal of useless rules via CPP but via `if (0)', so that the
5354 compiler still check the code is valid.
5355 For instance, it should have noticed `rline' no longer exists: use
5356 the `line' member of rule_t.
5357 * src/gram.c (dummy, rline): Remove, unused.
5358
5359 2001-12-05 Akim Demaille <akim@epita.fr>
5360
5361 * src/output.c (pack_vector): Use assert, not berror.
5362 * src/main.c (berror): Remove, unused.
5363
5364 2001-12-05 Akim Demaille <akim@epita.fr>
5365
5366 New experimental feature: if --verbose --trace output all the
5367 items of a state, not only its kernel.
5368
5369 * src/print.c (print_core): If `trace_flag', then invoke closure
5370 before outputting the items of the state (print_core is no longer
5371 a correct name them).
5372 (print_results): Invoke new_closure/free_closure if needed.
5373
5374 2001-12-05 Akim Demaille <akim@epita.fr>
5375
5376 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
5377 * src/closure.c, src/closure.h (itemsetsize): Rename as...
5378 (nitemset): for consistency with the rest of the project.
5379
5380 2001-12-05 Akim Demaille <akim@epita.fr>
5381
5382 * src/closure.c (print_closure): Improve.
5383 (closure): Use it for printing input and output.
5384
5385 2001-12-05 Akim Demaille <akim@epita.fr>
5386
5387 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5388 indexed by nonterminals.
5389
5390 2001-12-05 Akim Demaille <akim@epita.fr>
5391
5392 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
5393 what it was!).
5394 * src/warshall.h: Remove accidental duplication of the content.
5395
5396 2001-12-05 Akim Demaille <akim@epita.fr>
5397
5398 * src/closure.c (set_fderives): De-obfuscate.
5399
5400 2001-12-05 Akim Demaille <akim@epita.fr>
5401
5402 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
5403
5404 2001-12-05 Akim Demaille <akim@epita.fr>
5405
5406 * src/closure.c (set_firsts): De-obfuscate.
5407
5408 2001-12-05 Akim Demaille <akim@epita.fr>
5409
5410 * src/output.c (action_row): De-obfuscate
5411 using the good o' techniques: arrays not pointers, variable
5412 locality, BITISSET, RESETBIT etc.
5413
5414 2001-12-05 Akim Demaille <akim@epita.fr>
5415
5416 Pessimize the code to simplify it: from now on, all the states
5417 have a valid SHIFTS, which NSHIFTS is possibly 0.
5418
5419 * src/LR0.c (shifts_new): Be global and move to..
5420 * src/state.c, src/state.h: here.
5421 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
5422 * src/print_graph: Adjust.
5423
5424 2001-12-05 Akim Demaille <akim@epita.fr>
5425
5426 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
5427 * src/conflicts.c: Use it.
5428 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
5429 incorrectly ``simplified''.
5430
5431 2001-12-05 Akim Demaille <akim@epita.fr>
5432
5433 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
5434 using the good o' techniques: arrays not pointers, variable
5435 locality, BITISSET, RESETBIT etc.
5436
5437 2001-12-05 Akim Demaille <akim@epita.fr>
5438
5439 * src/state.h (SHIFT_SYMBOL): New.
5440 * src/conflicts.c: Use it to deobfuscate.
5441
5442 2001-12-05 Akim Demaille <akim@epita.fr>
5443
5444 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
5445 (print_reductions): De-obfuscate using the good o' techniques:
5446 arrays not pointers, variable locality, BITISSET.
5447
5448 2001-12-05 Akim Demaille <akim@epita.fr>
5449
5450 * src/conflicts.c (print_reductions): Arrays, not pointers.
5451 Use BITISSET.
5452
5453 2001-12-05 Akim Demaille <akim@epita.fr>
5454
5455 * src/conflicts.c (print_reductions): Pessimize, but clarify.
5456
5457 2001-12-05 Akim Demaille <akim@epita.fr>
5458
5459 * src/conflicts.c (print_reductions): Improve variable locality.
5460
5461 2001-12-05 Akim Demaille <akim@epita.fr>
5462
5463 * src/conflicts.c (print_reductions): Pessimize, but clarify.
5464
5465 2001-12-05 Akim Demaille <akim@epita.fr>
5466
5467 * src/conflicts.c (print_reductions): Improve variable locality.
5468
5469 2001-12-05 Akim Demaille <akim@epita.fr>
5470
5471 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
5472 * src/lalr.c: Use them.
5473
5474 2001-12-05 Akim Demaille <akim@epita.fr>
5475
5476 * src/LR0.c (augment_automaton): Formatting changes.
5477 Better variable locality.
5478
5479 2001-12-05 Akim Demaille <akim@epita.fr>
5480
5481 * src/lalr.c (matrix_print): New.
5482 (transpose): Use it.
5483 Use arrays instead of pointers.
5484
5485 2001-12-05 Akim Demaille <akim@epita.fr>
5486
5487 * src/lalr.c (maxrhs): Move to...
5488 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5489 * src/lalr.c (build_relations): Adjust.
5490
5491 2001-12-05 Akim Demaille <akim@epita.fr>
5492
5493 * src/lalr.c (transpose): Free the memory allocated to the
5494 argument, as it is replaced by the results by the unique caller.
5495 (build_relations): Merely invoke transpose: it handles the memory
5496 deallocation.
5497 Improve variable locality.
5498 Avoid variables used as mere abbreviations.
5499 (compute_lookaheads): Use arrays instead of pointers.
5500
5501 2001-12-05 Akim Demaille <akim@epita.fr>
5502
5503 * src/lalr.c (initialize_F): Improve variable locality.
5504 Avoid variables used as mere abbreviations.
5505
5506 2001-12-05 Akim Demaille <akim@epita.fr>
5507
5508 * src/derives.c (print_derives): Display the ruleno.
5509 * src/lalr.c (initialize_F, transpose): Better variable locality
5510 to improve readability.
5511 Avoid variables used as mere abbreviations.
5512
5513 2001-12-05 Akim Demaille <akim@epita.fr>
5514
5515 * src/lalr.c (traverse): Use arrays instead of pointers.
5516
5517 2001-12-05 Akim Demaille <akim@epita.fr>
5518
5519 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5520 the handling of squeue.
5521 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5522
5523 2001-12-05 Akim Demaille <akim@epita.fr>
5524
5525 Because useless nonterminals are now kept alive (instead of being
5526 `destroyed'), we now sometimes examine them, and store information
5527 related to them. Hence we need to know their number, and adjust
5528 memory allocations.
5529
5530 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5531 static.
5532 * src/LR0.c (allocate_itemsets): The memory allocated to
5533 `symbol_count' was used for two different purpose: once to count
5534 the number of occurrences of each symbol, and later reassigned to
5535 `shift_symbol', containing the symbol that can be shifted from a
5536 given state.
5537 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5538 only, and...
5539 (new_itemsets): Allocate `shift_symbol' here.
5540 (allocate_itemsets): symbol_count includes useless nonterminals.
5541 Make room for them.
5542 (free_storage): Use `free', not `XFREE', for pointers that cannot
5543 be null.
5544
5545 2001-12-05 Akim Demaille <akim@epita.fr>
5546
5547 * src/nullable.c (set_nullable): Deobfuscate the handling of
5548 ritem.
5549 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5550
5551 2001-12-05 Akim Demaille <akim@epita.fr>
5552
5553 * src/gram.c, src/gram.h (ritem_print): New.
5554 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5555 (This useless function was defined only to work around VMS linkers
5556 that can't handle compilation units with variables only).
5557 * src/reduce.c (dump_grammar): Use it to trace the construction of
5558 ritem.
5559
5560 2001-12-04 Paul Eggert <eggert@twinsun.com>
5561
5562 * src/bison.simple (union yyalloc): Change member names
5563 to be the same as the stack names.
5564 (yyparse): yyptr is now union yyalloc *, not char *.
5565 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5566 and may generate better code on some machines.
5567 (yystpcpy): Use prototype if __STDC__ is defined, not just
5568 if __cplusplus is defined.
5569
5570 2001-11-30 Akim Demaille <akim@epita.fr>
5571
5572 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
5573 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
5574 Gettext doesn't compile cleanly, and dies with -Werror.
5575 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
5576 Include WARNING_CFLAGS here.
5577 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
5578 before being defined.
5579
5580 2001-11-27 Paul Eggert <eggert@twinsun.com>
5581
5582 * lib/quotearg.h (quotearg_n, quotearg_n_style):
5583 First arg is int, not unsigned.
5584 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
5585 (SIZE_MAX, UINT_MAX): New macros.
5586 (quotearg_n_options): Abort if N is negative.
5587 Avoid overflow check on hosts where size_t is 64 bits and int
5588 is 32 bits, as overflow is impossible there.
5589 Fix off-by-one typo that caused unnecessary reallocation.
5590
5591 2001-11-29 Paul Eggert <eggert@twinsun.com>
5592
5593 Name space cleanup in generated parser.
5594
5595 * doc/bison.texinfo (Bison Parser): Discuss system headers
5596 and their effect on the user name space.
5597
5598 * src/bison.simple:
5599 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
5600 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
5601 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
5602
5603 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
5604 on user names when possible.
5605
5606 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5607 Simplify test for whather <alloca.h> exists.
5608
5609 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
5610
5611 (<stdio.h>): Include if YYDEBUG.
5612
5613 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5614 ! defined (yyoverflow) && ! defined (yymemcpy).
5615
5616 (yymemcpy, yyparse): Rename local variables as needed so that
5617 they all begin with 'yy'.
5618
5619 (yystrlen, yystpcpy): New functions.
5620
5621 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5622 All uses changed.
5623
5624 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5625 instead of relying on string.h functions. Use YYSTACK_ALLOC
5626 and YYSTACK_FREE instead of malloc and free.
5627
5628 2001-11-30 Akim Demaille <akim@epita.fr>
5629
5630 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
5631 before their first uses.
5632 (YYBISON, YYPURE): Move to the top of the output.
5633
5634 2001-11-30 Akim Demaille <akim@epita.fr>
5635
5636 * tests/reduce.at (Useless Nonterminals): Fix.
5637
5638 2001-11-30 Akim Demaille <akim@epita.fr>
5639
5640 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5641 if body instead of `;' to pacify GCC's warnings.
5642
5643 2001-11-30 Akim Demaille <akim@epita.fr>
5644
5645 Instead of mapping the LHS of unused rules to -1, keep the LHS
5646 valid, but flag the rules as invalid.
5647
5648 * src/gram.h (rule_t): `useful' is a new member.
5649 * src/print.c (print_grammar): Adjust.
5650 * src/derives.c (set_derives): Likewise.
5651 * src/reader.c (packgram, reduce_output): Likewise.
5652 * src/reduce.c (reduce_grammar_tables): Likewise.
5653 * tests/reduce.at (Underivable Rules, Useless Rules): New.
5654
5655 2001-11-30 Akim Demaille <akim@epita.fr>
5656
5657 * src/reduce.c (reduce_output): Formatting changes.
5658 * src/print.c (print_results, print_grammar): Likewise.
5659 * tests/regression.at (Rule Line Numbers)
5660 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
5661
5662 2001-11-30 Akim Demaille <akim@epita.fr>
5663
5664 * src/reduce.c (nonterminals_reduce): Instead of throwing away
5665 useless nonterminals, move them at the end of the symbol arrays.
5666 (reduce_output): Adjust.
5667 * tests/reduce.at (Useless Nonterminals): Adjust.
5668
5669 2001-11-30 Akim Demaille <akim@epita.fr>
5670
5671 * src/reduce.c: Various comment/formatting changes.
5672 (nonterminals_reduce): New, extracted from...
5673 (reduce_grammar_tables): here.
5674 (reduce_grammar): Call nonterminals_reduce.
5675
5676 2001-11-29 Paul Eggert <eggert@twinsun.com>
5677
5678 * src/bison.simple (YYSTACK_REALLOC): Remove.
5679 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
5680 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5681 New macros.
5682 (union yyalloc): New type.
5683 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5684 an arbitrary restriction on hosts where size_t is wider than int.
5685
5686 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5687 a parser stack overflow. Allocate just one block of memory for all
5688 three stacks, instead of allocating three blocks; this typically is
5689 faster and reduces fragmentation.
5690
5691 Do not limit the number of items in the stack to a value that fits
5692 in 'int', as this is an arbitrary limit on hosts with 64-bit
5693 size_t and 32-bit int.
5694
5695 2001-11-29 Marc Autret <autret_m@epita.fr>
5696
5697 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
5698 of defining YYERROR_VERBOSE.

7072
7073 * src/bison.simple (yyparse): Don't take the address of an
7074 item before the start of an array, as that doesn't conform to
7075 the C Standard.
7076
7077 2001-08-27 Robert Anisko <robert.anisko@epita.fr>
7078
7079 * src/output.c (output): Remove the initialization of the macro
7080 obstack. It was done too late here.
7081
7082 * src/reader.c (parse_macro_decl): Fix. Use of the macro obstack was
7083 completely wrong.
7084 (reader): Initialize the macro obstack here, since we need it to grow
7085 '%define' directives.

7122 bound to true.
7123 (read_declarations): Add case for macro definition.
7124 (copy_identifier): New.
7125 (parse_macro_decl): Read macro identifiers using copy_identifier
7126 rather than lex.

7130 * src/output.c (prepare): Add prefixed names.
7131 (output_parser): Output semantic actions.
7132 (output_parser): Fix bug on '%%line' directives.
7133
7134 * src/output.c (output_headers): Remove. The C code printed by this
7135 function should now be in the skeletons.
7136 (output_trailers): Remove.
7137 (output): Disable call to 'reader_output_yylsp'.
7138 (output_rule_data): Do not output tables to the table obstack.

7157 (output_short_or_char_table): Remove.
7158
7159 * src/output.c (output_parser): Replace most of the skeleton copy code
7160 with something new. Skeletons are now processed character by character
7161 rather than line by line, and Bison looks for '%%' macros. This is the
7162 first step in making Bison's output process (a lot) more flexible.
7163 (output_parser): Use the macro table.
7164
7165 2001-08-25 Robert Anisko <robert.anisko@epita.fr>

7533 Let them be enums, not #define, to ease debugging.
7534 Adjust all the code.
7535
7536 2001-01-18 Akim Demaille <akim@epita.fr>
7537
7538 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

7540
7541 2001-01-18 Akim Demaille <akim@epita.fr>
7542
7543 Since we now use obstacks, more % directives can be enabled.
7544
7545 * src/lex.c (percent_table): Also accept `%yacc',
7546 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
7547 `%debug'.
7548 Handle the actions for `%semantic_parser' and `%pure_parser' here,
7549 instead of returning a token.
7550 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
7551 * src/reader.c (read_declarations): Adjust.
7552 * src/files.c (open_files): Don't call `compute_base_names', don't
7553 compute `attrsfile' since they depend upon data which might be
7554 *in* the input file now.
7555 (output_files): Do it here.
7556 * src/output.c (output_headers): Document the fact that this patch
7557 introduces a guaranteed SEGV for semantic parsers.
7558 * doc/bison.texinfo: Document them.

7576 in the case of `-o foo.tab.c'.
7577
7578 2000-12-20 Akim Demaille <akim@epita.fr>
7579
7580 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
7581 (copy_dollar): Now that everything uses obstacks, get rid of the
7582 FILE * parameters.
7583
7584 2000-12-20 Akim Demaille <akim@epita.fr>
7585
7586 * src/files.c (open_files): Actually the `.output' file is based
7587 on the short_base_name, not base_name.
7588 * tests/suite.at (Checking output file names): Adjust.
7589
7590 2000-12-20 Akim Demaille <akim@epita.fr>

7594 * src/Makefile.am: Use pkgdata instead of data.
7595
7596 2000-12-20 Akim Demaille <akim@epita.fr>

7612
7613 2000-12-19 Akim Demaille <akim@epita.fr>
7614
7615 * src/files.c (strsuffix): New.
7616 (stringappend): Be just like strcat but allocate.
7617 (base_names): Eve out from open_files.
7618 Try to simplify the rather hairy computation of base_name and
7619 short_base_name.
7620 (open_files): Use it.
7621 * tests/suite.at (Checking output file names): New test.
7622

7626 (obstack_grow_string): this.
7627 * src/output.c (output_parser): Recognize `%% actions' instead of

7637 Suggested by Hans Aberg.
7638
7639 2000-12-19 Akim Demaille <akim@epita.fr>
7640
7641 Let the handling of the skeleton files be local to the procedures

7650 skeleton.
7651 * src/reader.c (read_declarations): When %semantic_parser, open

7658
7659 2000-12-19 Akim Demaille <akim@epita.fr>
7660
7661 * src/files.c (open_files): Yipee! We no longer need all the code
7662 looking for `/tmp' since we have no tmp file.
7663
7664 2000-12-19 Akim Demaille <akim@epita.fr>
7665
7666 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

7692
7693 * lib/obstack.h: Formatting changes.
7694 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
7695 prevents type checking.
7696 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
7697 cast the value to (void *): assigning a `foo *' to a `void *'
7698 variable is valid.
7699 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
7700 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7714
7715 2000-11-17 Akim Demaille <akim@epita.fr>
7716
7717 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
7718 macros.
7719 Use them to declare the variables which are global or local to

7742
7743 * src/output.c (output): Remove useless variables.
7744 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
7745 argument `data' for consistency with the prototypes.
7746 Qualify it `const'.
7747 (obstack_copy, obstack_copy0): Rename the second argument as
7748 `address' for consistency. Qualify it `const'.
7749 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
7750 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
7751 `const' their input argument (`data' or `address').
7752 Adjust the corresponding macros to include `const' in casts.
7753
7754 2000-11-03 Akim Demaille <akim@epita.fr>
7755
7756 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

7761
7762 For some reason, this was not applied.
7763
7764 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

7773
7774 Don't use `atexit'.
7775
7776 * src/files.c (obstack_save): New function.
7777 (done): Rename as...
7778 (output_files): this.
7779 Use `obstack_save'.
7780 * src/main.c (main): Don't use `atexit' to register `done', since
7781 it no longer has to remove tmp files, just call `output_files'
7782 when there are no errors.
7783
7784 2000-11-02 Akim Demaille <akim@epita.fr>
7785
7786 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

7793
7794 * src/files.c (fdefines, ftable): Removed.
7795 (defines_ostack, table_obstack): New.

7805
7806 Change each use of `fattrs' into a use of `attrs_obstack'.
7807
7808 * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
7809 * src/files.c (fattrs): Remove.

7840 comment associated with the table.
7841 Adjust dependencies.
7842 (output_gram): Use it.

7844
7845 2000-10-16 Akim Demaille <akim@epita.fr>
7846
7847 * src/lex.c (read_typename): New function.
7848 (lex): Use it.
7849 * src/reader.c (copy_dollar): Likewise.
7850
7851 2000-10-16 Akim Demaille <akim@epita.fr>
7852
7853 * src/reader.c (copy_comment2): Expect the input stream to be on
7854 the `/' which is suspected to open a comment, instead of being
7855 called after `//' or `/*' was read.
7856 (copy_comment, copy_definition, parse_union_decl, copy_action)
7857 (copy_guard): Adjust.
7858
7859 2000-10-16 Akim Demaille <akim@epita.fr>

7881 2000-10-04 Akim Demaille <akim@epita.fr>
7882
7883 * doc/bison.texinfo: Various typos spotted by Neil Booth.
7884
7885 2000-10-04 Akim Demaille <akim@epita.fr>
7886
7887 When a literal string is used to define two different tokens,
7888 `bison -v' segfaults.
7889 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
7890
7891 * tests/regression.m4: New file.
7892 Include the core of the sample provided by Piotr Gackiewicz.

7894 properly.
7895
7896 2000-10-04 Akim Demaille <akim@epita.fr>
7897
7898 * src/reader.c (parse_expect_decl): Keep `count' within the size
7899 of `buffer'.
7900 From Neil Booth.
7901
7902 2000-10-02 Paul Eggert <eggert@twinsun.com>
7903
7904 * bison.s1 (yyparse): Assign the default value
7905 unconditionally, to avoid a GCC warning and make the parser a
7906 tad smaller.
7907
7908 2000-10-02 Akim Demaille <akim@epita.fr>
7909
7910 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
7911 options.
7912
7913 2000-10-02 Akim Demaille <akim@epita.fr>
7914
7915 * src/derives.c, src/print.c, src/reduce.c: To ease the
7916 translation, move some `\n' out of the translated strings.
7917
7918 2000-10-02 Akim Demaille <akim@epita.fr>
7919
7920 The location tracking mechanism is precious for parse error
7921 messages. Nevertheless, it is enabled only when `@n' is used in
7922 the grammar, which is a different issue (you can use it in error
7923 message, but not in the grammar per se). Therefore, there should
7924 be another means to enable it.
7925
7926 * src/getargs.c (getargs): Support `--locations'.
7927 (usage): Report it.
7928 * src/getargs.h (locationsflag): Export it.
7929 * src/lex.c (percent_table): Support `%locations'.
7930 * src/reader.c (yylsp_needed): Remove this variable, now replaced
7931 with `locationsflag'.
7932 * doc/bison.texinfo: Document `--locations' and `%locations'.
7933 Sort the options.
7934 * tests/calc.m4: Test it.
7935
7936 For regularity of the names, replace each
7937 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7938 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7939 In addition replace each `flag' with `_flag'.
7940
7941 2000-10-02 Akim Demaille <akim@epita.fr>
7942
7943 Also test parse error messages, including with YYERROR_VERBOSE.
7944
7945 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7946 associative).
7947 Use it to check the computations.
7948 Use it to check `nonassoc' is honored.
7949 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7950 `--yyerror-verbose'.
7951 (_AT_CHECK_CALC): Adjust to this option.
7952 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7953
7954 2000-10-02 Akim Demaille <akim@epita.fr>
7955
7956 Test also `--verbose', `--defines' and `--name-prefix'. Testing
7957 the latter demonstrates a flaw in the handling of non debugging
7958 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7959 was used in order to simplify:
7960
7961 #if YYDEBUG
7962 if (yydebug)
7963 {
7964 ...
7965 }
7966 #endif
7967
7968 into
7969
7970 if (yydebug)
7971 {
7972 ...
7973 }
7974
7975 unfortunately this leads to a CPP conflict when
7976 `--name-prefix=foo' is used since it produces `#define yydebug
7977 foodebug'.
7978
7979 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7980 (YYDPRINTF): New macro.
7981 Spread its use.
7982 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7983 the bison options.
7984 Also test `--verbose', `--defines' and `--name-prefix'.
7985
7986 2000-10-02 Akim Demaille <akim@epita.fr>
7987
7988 Improve the readability of the produced parsers.
7989
7990 * src/bison.s1: Formatting changes.
7991 Improve the comment related to the `$' mark.
7992 (yydefault): Don't fall through to `yyresume': `goto' there.
7993 * src/output.c (output_parser): When the `$' is met, skip the end
7994 of its line.
7995 New variable, `number_of_dollar_signs', to check there's exactly
7996 one `$' in the parser skeleton.
7997

8000 * lib/xstrdup.c: New file, from the fileutils.
8001 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
8002 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
8003 instead of strlen + xmalloc + strcpy.
8004 * src/symtab.c (copys): Remove, use xstrdup instead.
8005
8006 2000-10-02 Akim Demaille <akim@epita.fr>
8007
8008 * src/gram.h (associativity): New enum type which replaces the
8009 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
8010 `right_assoc', `left_assoc' and `non_assoc'.
8011 Adjust all dependencies.
8012 * src/reader.c: Formatting changes.
8013 (LTYPESTR): Don't define it, use it as a literal in
8014 `reader_output_yylsp'.
8015 * src/symtab.h (symbol_class): New enum type which replaces the
8016 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
8017 `sunknown', `stoken and `snterm'.
8018
8019 2000-10-02 Akim Demaille <akim@epita.fr>

8024
8025 2000-10-02 Akim Demaille <akim@epita.fr>
8026
8027 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
8028 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
8029 difficult and introduced a lot of core dump. It turns out that
8030 Bison used an implementation of `xmalloc' based on `calloc', and
8031 at various places it does depend upon the initialization to 0. I
8032 have not tried to isolate the pertinent places, and all the former
8033 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
8034 someone should address this issue.
8035
8036 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
8037 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

8046
8047 * src/system.h: Include `assert.h'.
8048
8049 2000-10-02 Akim Demaille <akim@epita.fr>
8050
8051 * src/state.h (nstates, final_state, first_state, first_shift)
8052 (first_reduction): Move their exportation from here...
8053 * src/LR0.h: to here.
8054 Adjust dependencies.
8055 * src/getargs.c (statisticsflag): New variable.
8056 Add support for `--statistics'.

8060
8061 2000-10-02 Akim Demaille <akim@epita.fr>
8062
8063 * src/LR0.h: New file.

8133 output_short_table.
8134
8135 2000-10-02 Akim Demaille <akim@epita.fr>
8136
8137 `user_toknums' is output as a `short[]' in `output.c', while it is
8138 defined as a `int[]' in `reader.c'. For consistency with the
8139 other output tables, `user_toknums' is now defined as a table of
8140 shorts.
8141
8142 * src/reader.c (user_toknums): Be a short table instead of an int
8143 table.

8153
8154 * src/output.c (output): Topological sort of the functions, in
8155 order to get rid of the `static' prototypes.
8156 No longer use `register'.
8157 * src/output.h: New file.
8158 Propagate its inclusion in files explicitly prototyping functions
8159 from output.c.

8181 inclusion.
8182 Don't define PARAMS.
8183 * src/system.h: Define PARAMS.
8184 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
8185 purpose of config.h. system.h must not try to fix wrong
8186 definitions in config.h.
8187
8188 2000-09-20 Akim Demaille <akim@epita.fr>
8189

8280
8281 * src/files.c (tryopen, tryclose): Move to the top.

8287
8288 2000-03-31 Akim Demaille <akim@epita.fr>
8289

8321 * lib/: New directory.
8322 * Makefile.am (SUBDIRS): Adjust.
8323 * configure.in: Adjust.
8324 (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's
8325 useless.

8346
8347 * src/Makefile.am (bison.simple): Fix the awk program: quote only
8348 the file name, not the whole `#line LINE FILE'.
8349
8350 2000-03-17 Akim Demaille <akim@epita.fr>
8351
8352 On syntax errors, report the token on which we choked.
8353
8354 * src/bison.s1 (yyparse): In the label yyerrlab, when
8355 YYERROR_VERBOSE, add yychar in msg.

8370
8371 2000-03-17 Akim Demaille <akim@epita.fr>

8378
8379 2000-03-17 Akim Demaille <akim@epita.fr>

8382 problems with inline, since it is checked by configure.
8383 (copy_comment): Likewise.
8384
8385 2000-03-17 Akim Demaille <akim@epita.fr>
8386
8387 * src/reader.c (packsymbols): Formatting changes.

8390
8391 * src/reader.c (copy_comment): New function, factored out from:
8392 (copy_action): Use it. Removed now unused `match', `ended',
8393 `cplus_comment'.

8399 (copy_action): Use it.
8400 (copy_guard): Likewise.
8401
8402 2000-03-17 Akim Demaille <akim@epita.fr>
8403
8404 Change the handling of @s so that they behave exactly like $s.
8405 There is now a pseudo variable @$ (readble and writable), location
8406 of the lhs of the rule (by default ranging from the location of
8407 the first symbol of the rhs, to the location of the last symbol,
8408 or, if the rhs is empty, YYLLOC).
8409
8410 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
8411 yyval.
8412 (yyparse): When providing a default semantic action, provide a
8413 default location action.
8414 (after the $): No longer change `*YYLSP', just stack YYLOC the
8415 same way you stack YYVAL.
8416 * src/reader.c (read_declarations): Use warns.
8417 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
8418 (copy_action, case '@'): Likewise.
8419 Use a standard error message, to save useless work from
8420 translators.
8421
8422 2000-03-17 Akim Demaille <akim@epita.fr>

8434
8435 * src/output.c (output_rule_data): Output the documentation of

8440 2000-03-16 Akim Demaille <akim@epita.fr>
8441
8442 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
8443 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
8444 One `#if YYDEBUG' remains, since it uses variables which are
8445 defined only if `YYDEBUG != 0'.
8446
8447 2000-03-16 Akim Demaille <akim@epita.fr>
8448
8449 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

8456 2000-03-16 Akim Demaille <akim@epita.fr>
8457
8458 * src/bison.s1: Properly indent the `alloca' CPP section.
8459
8460 2000-03-16 Akim Demaille <akim@epita.fr>
8461
8462 Do not hard code values of directories in `configure.in'.
8463 Update the `configure' tool chain.
8464
8465 * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
8466 src/makefile.am.
8467 (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
8468 (AC_OUTPUT): Add m4/Makefile.
8469 Bump to bison 1.28a, 1.29 has never been released.
8470 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are

9119 inside grammar rules: The documentation doesn't allow it,
9120 and it will fail since the %command processors scan for the next %.

9122 declaration to allow a multi-character symbol as an alias.
9123 (parse_thong_decl): New function.

9134 Revised and use multiple warnxxx functions to avoid using VARARGS1.
9135 (read_declarations): Improve the error message for
9136 an invalid character. Do not abort.
9137 (read_declarations, copy_guard, copy_action): Use
9138 printable_version to avoid unprintable characters in printed output.
9139 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
9140 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

9164 (lex): Use literalchar.
9165 (lex): Implemented "..." tokens.
9166 (literalchar, lex, parse_percent_token): Made tokenbuffer
9167 always contain the token. This includes growing the token
9168 buffer while reading an integer.
9169 (parse_percent_token): Replaced if-else statement with percent_table.
9170 (parse_percent_token): Added % declarations as another
9171 way to specify the flags -n, -l, and -r. Also added hooks for
9172 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
9173 major changes to files.c.
9174 (lex) Retain in the incoming stream a character following
9175 an incorrect '/'.
9176 (skip_white_space, lex): Revised most error messages
9177 and changed fatal to warn to avoid aborting.
