[bison.git] / ChangeLog
1 2002-11-16 Akim Demaille <akim@epita.fr>
2
3 Augment the similarity between GLR and LALR traces.
4
5 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
6 (YY_REDUCE_PRINT): New.
7 (yyparse): Use them.
8 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
9 YYDPRINT here.
10 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11 state reached after the reduction/recovery, since...
12 (yyparse, yyprocessOneStack): Report the state we are entering in.
13
14 2002-11-16 Akim Demaille <akim@epita.fr>
15
16 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
17 Add support for --trace=skeleton.
18 * src/scan-skel.l: %option debug.
19 Scan strings of non-@ or \n instead of character by character.
20 (scan_skel): Handle trace_skeleton.
21 (QPUTS): New.
22 (@output_parser_name@, @output_header_name@): ``Restore'' their
23 support (used to be M4 macros).
24 * data/yacc.c: Quote larger chunks, a la glr.c.
25 * data/lalr1.cc: Likewise.
26 The header guards are no longer available, so use some other
27 string than `YYLSP_NEEDED'.
28
29 2002-11-16 Akim Demaille <akim@epita.fr>
30
31 Make the ``Printers and Destructors'' test more verbose, taking
32 `yacc.c''s behavior as (possibly wrong) reference.
33
34 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
35 instead of fprint on stdout.
36 Set and report the last_line of the symbols.
37 Consistently display values and locations.
38
39 2002-11-16 Paul Eggert <eggert@twinsun.com>
40
41 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
42
43 2002-11-15 Paul Eggert <eggert@twinsun.com>
44
45 * tests/actions.at (Actions after errors): New test case.
46
47 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
48 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
49 tests/action.at, tests/calc.at, tests/conflicts.at,
50 tests/cxx-type.at, tests/regression.at:
51 "parse error" -> "syntax error" for POSIX compatibility.
52 "parsing stack overflow..." -> "parser stack overflow" so
53 that code matches Bison documentation.
54
55 2002-11-15 Akim Demaille <akim@epita.fr>
56
57 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
58 take two BRACED_CODE, not two string_content.
59 Free the scanner's obstack when we are done.
60 (code_content): New.
61 * tests/calc.at: Adjust.
62 * doc/bison.texinfo: Adjust.
63 Also, make sure to include the `,' for these declarations.
64
65 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
66
67 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
68 definition; avoids potential autoreconf problems.
69
70 2002-11-15 Akim Demaille <akim@epita.fr>
71
72 Always check the value returned by yyparse.
73
74 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
75 returned by yyparse.
76 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
77 Adjust calls.
78 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
79 returned by yyparse.
80
81 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
82
83 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
84 on input.at test.
85
86 2002-11-14 Paul Eggert <eggert@twinsun.com>
87
88 * src/output.c (output_skeleton): Call xfopen instead of
89 duplicating xfopen's body.
90
91 Fix bugs reported by Nelson H. F. Beebe in
92 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
93
94 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
95 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
96 Group compiler. Instead, use "$CC -E bar.c". Include the .h
97 file twice in the grammar, as an extra check.
98
99 * tests/input.at (Torturing the Scanner): Surround the
100 backslash-newline tests with "#if 0", to make it less likely that
101 we'll run into compiler bugs. Bring back solitary \ inside
102 comment, but add a closing comment to work around HP C bug. Don't
103 test backslash-newline in C character constant. This should fix
104 the input.at bug reported by Nelson H. F. Beebe in
105 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
106
107 2002-11-14 Akim Demaille <akim@epita.fr>
108
109 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
110 status of the compiler.
111 Calling `exit 1' is no longer needed.
112 Reported by Nelson H. F. Beebe.
113
114 2002-11-14 Akim Demaille <akim@epita.fr>
115
116 * tests/atlocal.in (CPPFLAGS): We have config.h.
117 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
118 New.
119 * tests/actions.at, tests/calc.at, tests/conflicts.at,
120 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
121 * tests/regression.at, tests/torture.at: Use them for all the
122 grammars that are to be compiled.
123 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
124 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
125 * doc/bison.texinfo (GLR Parsers): Document `inline'.
126
127 2002-11-14 Akim Demaille <akim@epita.fr>
128
129 * doc/bison.texinfo: Various formatting changes (alignments in
130 samples, additional @group/@end group, GCS in samples.
131 Use @deffn instead of simple @table to define the directives,
132 macros, variables etc.
133
134 2002-11-13 Paul Eggert <eggert@twinsun.com>
135
136 Fix some bugs reported by Albert Chin-A-Young in
137 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
138
139 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
140 -o c"; the HP C compiler chatters during compilation.
141 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
142 * tests/headers.at (export YYLTYPE): Likewise.
143
144 * tests/input.at (Torturing the Scanner): Remove lines containing
145 solitary backslashes, as they tickle a bug in the HP C compiler.
146
147 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
148 comments, since they're not portable. Use GNU coding style.
149
150 2002-11-13 Akim Demaille <akim@epita.fr>
151
152 * data/yacc.c: Leave bigger chunks of quoted text.
153 (YYDSYMPRINTF): New.
154 Use it to report symbol activities.
155 * data/glr.c (YYDSYMPRINTF): New.
156 Use it.
157
158 2002-11-12 Paul Eggert <eggert@twinsun.com>
159
160 Version 1.75b.
161
162 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
163 (yyglrReduce): Return yyok, not 0.
164 This should avoid the enumerated-type warnings reported
165 by Nelson H.F. Beebe in
166 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.
167
168 * lib/bbitset.h (BITSET_INLINE): Remove.
169 * lib/bitset.h [! BITSET_INLINE]: Remove.
170 (bitset_set, bitset_reset, bitset_test): Rename local vars
171 to avoid shadowing warnings by GCC.
172
173 * data/glr.c (inline): Remove #define. It's the user's
174 responsibility to #define it away, just like 'const'.
175 This fixes one of the bugs reported by Nelson H.F. Beebe in
176 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>.
177
178 * Makefile.maint (po-check): Scan .l and .y files instead of the
179 .c and the .h files that they generate. This fixes the bug
180 reported by Tim Van Holder in:
181 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
182 Look for N_ as well as for _. Try to avoid matching #define for
183 N_ and _.
184 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
185 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
186 * src/scan-gram.l: Revamp regular expressions so that " and '
187 do not confuse xgettext.
188
189 * src/struniq.h (struniq_new): Do not declare the return type
190 to be 'const'; this violates the C standard.
191 * src/struniq.c (struniq_new): Likewise.
192
193 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
194
195 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
196 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
197 linker.
198
199 2002-11-12 Akim Demaille <akim@epita.fr>
200
201 * Makefile.maint: Sync with Autoconf:
202 (local_updates): New.
203
204 2002-11-12 Akim Demaille <akim@epita.fr>
205
206 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
207
208 2002-11-12 Akim Demaille <akim@epita.fr>
209
210 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
211 locations.
212
213 2002-11-12 Akim Demaille <akim@epita.fr>
214
215 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
216 not yyvalue.
217
218 2002-11-12 Akim Demaille <akim@epita.fr>
219
220 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
221 Use it to test the GLR parser.
222
223 2002-11-12 Akim Demaille <akim@epita.fr>
224
225 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
226 defines it.
227 * data/glr.c (yystos): New.
228 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
229 (YYDSYMPRINT): New.
230 (yyval): Don't define it, it is handled via M4.
231 (yyrecoverParseError): Free verbosely the discarded symbols.
232 * data/yacc.c (yysymprint): Remove, rather...
233 (b4_yysymprint_generate): invoke.
234 * data/c.m4 (b4_yysymprint_generate): New.
235 Accept pointers as arguments, as opposed to the version from
236 yacc.c.
237 (b4_yydestruct_generate): Likewise.
238 * tests/cations.at (Printers and Destructors): Use Bison directives
239 instead of CPP macros.
240 Don't rely on internal details.
241
242 2002-11-12 Akim Demaille <akim@epita.fr>
243
244 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
245 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
246 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
247 it against YYEMPTY and so forth), work on yytoken (i.e., set
248 it to YYEMPTY etc.).
249 (yydestruct): Replace with a b4_yydestruct_generate invocation.
250 (b4_symbol_actions): Remove.
251 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
252 for 0, end-of-input.
253
254 2002-11-12 Akim Demaille <akim@epita.fr>
255
256 * doc/bison.texinfo (Destructor Decl): New.
257
258 2002-11-12 Akim Demaille <akim@epita.fr>
259
260 * src/tables.c (tables_generate): Use free for pointers that
261 cannot be NULL, not XFREE.
262 (pack_vector): Use assert, not fatal, for bound violations.
263 * src/state.c (state_new): Likewise.
264 * src/reader.c (reader): Likewise.
265 * src/lalr.c (set_goto_map): Likewise.
266 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
267 the file name.
268
269 2002-11-12 Akim Demaille <akim@epita.fr>
270
271 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
272 Restore.
273 * src/scan-gram.l (last_string): Is global to the file, not to
274 yylex.
275 * src/parse-gram.y (input): Don't append the epilogue here,
276 (epilogue.opt): do it here, and free the scanner's obstack.
277 * src/reader.c (epilogue_set): Rename as...
278 (epilogue_augment): this.
279 * data/c.m4 (b4_epilogue): Defaults to empty.
280
281 2002-11-12 Akim Demaille <akim@epita.fr>
282
283 * src/getargs.c (long_options): Remove duplicates.
284 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
285 Remove.
286 * doc/bison.rnh: Remove.
287 * doc/bison.texinfo (VMS Invocation): Remove.
288
289 2002-11-12 Akim Demaille <akim@epita.fr>
290
291 * src/struniq.h, src/struniq.c (struniq_t): Is const.
292 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
293
294 Use struniq for symbols.
295
296 * src/symtab.h (symbol_t): The tag member is a struniq.
297 (symbol_type_set): Adjust.
298 * src/symtab.c (symbol_new): Takes a struniq.
299 (symbol_free): Don't free the tag member.
300 (hash_compare_symbol_t, hash_symbol_t): Rename as...
301 (hash_compare_symbol, hash_symbol): these.
302 Use the fact that tags as struniqs.
303 (symbol_get): Use struniq_new.
304 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
305 Returns a strniq.
306 * src/reader.h (merger_list, grammar_currentmerge_set): The name
307 and type members are struniqs.
308 * src/reader.c (get_merge_function)

310 (TYPE, current_type): Are struniq.
311
312 Use struniq for file names.
313
314 * src/files.h, src/files.c (infile): Split into...

320 * src/main.c (main): Call struniqs_new early enough to use it for
321 file names.
322 Don't free the input file name.
323
324 2002-11-12 Akim Demaille <akim@epita.fr>
325

335 * src/symtab.h (symbol_t): The 'type_name' member is a struniq.
336
337 2002-11-11 Paul Eggert <eggert@twinsun.com>
338
339 Revamp to fix many (but not all) of the C- and M4-related quoting
340 problems. Among other things, this fixes the Bison bug reported
341 by Jan Hubicka when processing the Bash grammar; see:
342 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html>
343
344 Use new @ escapes consistently. Represent brackets with @{ and @}
345 rather than @<:@ and @:>@, since this works a bit better with dumb
346 editors like vi. Represent @ with @@, since @ is now consistently
347 an escape. Use @oline@ and @ofile@ rather than __oline__ and
348 __ofile__, to avoid unexpected expansions. Similarly, use @output
349 rather than #output.
350
351 * data/c.m4 (b4_copyright): Omit file name from comment, since
352 the file name could contain "*/".
353 (b4_synclines_flag): Don't quote the 2nd argument; it should already
354 be quoted. All uses changed.
355
356 * data/glr.c: Use new @ escapes consistently.
357 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
358 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
359 Remove, since they couldn't handle arbitrary characters in file
360 names.
361 * data/lalr1.cc: Likewise.
362 * data/yacc.c: Likewise.
363
364 * src/files.c (output_infix): Remove; all uses removed.
365 * src/files.h: Likewise.
366
367 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
368 mishandled funny characters in file names, and anyway it isn't
369 needed any more.
370 * data/yacc.c: Likewise.
371 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
372
373 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
374 * data/yacc.c: Likewise.
375
376 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
377 strings now.
378 (muscle_init): Quote filename as a C string.
379 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
380 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
381 * src/output.c (escaped_file_name_output): New function.
382 (prepare_symbols): Quote tokens for M4.
383 (prepare): Don't insert output_infix, output_prefix,
384 output_parser_name, output_header_name; this is now down by scan-skel.
385 Insert skeleton as a C string.
386
387 * src/output.c (user_actions_output, symbol_destructors_output,
388 symbol_printers_output): Quote filenames for C and M4.
389 * src/reader.c (prologue_augment, epilogue_set): Likewise.
390
391 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
392 escapes other than \\ and \'; this simplifies the code.
393 (<SC_STRING>): Likewise, for \\ and \".
394 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
395 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
396 Use new escapes @{ and @} for [ and ].
397
398 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
399 them with auto vars.
400 Switch to new escape scheme, where @ is the escape character uniformly.
401 Abort if a stray escape character is found. Avoid unbounded input
402 buffer when parsing non-escaped text.
403
404 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
405 __oline__, #output, $@, and @{ do not have unintended meanings.
406
407 2002-11-09 Paul Eggert <eggert@twinsun.com>
408
409 Fix the test failure due to GCC warnings described in
410 <http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>.
411 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
412 evaluate to 0 if it's impossible for NINF to be in the respective
413 table.
414 (yygetLRActions, yyrecoverParseError): Use them.
415
416 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
417 counted in the token inserted at end of file. Now takes
418 location_t *, not location_t, so that the location can be
419 adjusted. All uses changed.
420
421 * tests/regression.at (Invalid inputs): Adjust wording in
422 diagnostic to match the new behavior.
423
424 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
425 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
426 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
427 abort ();'. This reduces the runtime of the "Many lookaheads"
428 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
429 GCC 3.2.
430
431 2002-11-07 Paul Eggert <eggert@twinsun.com>
432
433 * src/parse-gram.y (CHARACTER): Remove unused token.
434 All uses removed.
435
436 * src/scan-gram.l: Remove stack option. We no longer use the
437 stack, since the stack was never deeper than 1; instead, use the
438 new auto var c_context to record the stacked value.
439
440 Remove nounput option. At an unexpected end of file, we now unput
441 the minimal input necessary to end cleanly; this simplifies the
442 code.
443
444 Avoid unbounded token sizes where this is easy.
445
446 (unexpected_end_of_file): New function.
447 Use it to systematize the error message on unexpected EOF.
448 (last-string): Now auto, not static.
449 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
450 (scanner_last_string_free): Remove; not used.
451 (percent_percent_count): Move decl to just before use.
452 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,

474 Quote __ofile__.
475 * src/output.c (symbol_printers_output)

508 either has GLR conflict entries.
509
510 2002-11-05 Paul Eggert <eggert@twinsun.com>
511
512 * src/scan-gram.l: Use more accurate diagnostics, e.g.
513 "integer out of range" rather than "invalid value".
514 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
515 accordingly.
516
517 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
518 Also, remove one static variable in the scanner.
519
520 * src/scan-gram.l (braces_level): Now auto, not static.
521 Initialize to zero if the compiler is being picky.
522 (INITIAL): Clear braces_level instead of incrementing it.
523 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
524 as POSIX 1003.1-2001 requires.
525 * src/system.h (IF_LINT): New macro, taken from coreutils.
526 * configure.ac: Define "lint" if --enable-gcc-warnings.
527
528 2002-11-05 Akim Demaille <akim@epita.fr>
529
530 * src/scan-gram.l: When it starts with `%', complain about the
531 whole directive, not just that `invalid character: %'.
532
533 2002-11-04 Akim Demaille <akim@epita.fr>
534
535 * Makefile.maint: Update from Autoconf.
536 (update, cvs-update, po-update, do-po-update): New.
537
538 2002-11-04 Akim Demaille <akim@epita.fr>
539
540 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
541 and yyerror.
542 Have yyerror `use' its arguments.
543 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
544 returns true when location & yacc & pure & parse-param.
545 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
546
547 2002-11-04 Akim Demaille <akim@epita.fr>
548
549 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
550 clashes.
551 * src/scan-gram.l: Use [\'] instead of ['] to pacify
552 font-lock-mode.
553 Use complain_at.
554 Use quote, not quote_n since LOCATION_PRINT no longer uses the
555 slot 0.
556
557 2002-11-03 Paul Eggert <eggert@twinsun.com>
558
559 * src/reader.c (get_merge_function, grammar_current_rule_check):

563
564 2002-11-03 Akim Demaille <akim@epita.fr>
565
566 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
567 New.
568 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
569 (b4_parse_param): Remove.
570 Use b4_identification.
571 Propagate b4_pure_args where needed to pass them to yyerror.
572 * data/glr.m4 (b4_parse_param): Remove.

576 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
577 b4_user_formals and b4_user_args.

580 the location, and the parse-params.
581 Adjust callers.
582 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
583 When using a pure parser, also need the parse-params.
584 Adjust callers.
585 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
586 (%pure-parser + %parse-param) LALR and GLR parsers.
587 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
588 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
589 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
590 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
591 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.

598
599 2002-11-03 Akim Demaille <akim@epita.fr>
600
601 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
602 AT_CHECK_CALC_GLR invocations to use % directives, instead of
603 command line options.
604 * tests/cxx-type.at: Formatting changes.
605
606 2002-11-03 Paul Eggert <eggert@twinsun.com>
607
608 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
609 to count columns correctly, and to check for invalid inputs.
610
611 Use mbsnwidth to count columns correctly. Account for tabs, too.
612 Include mbswidth.h.
613 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
614 (extend_location): New function.
615 (YY_LINES): Remove.
616
617 Handle CRLF in C code rather than in Lex code.

623
624 Handle backslash-newline correctly in C code.
625 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
626 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
627 all uses changed.
628 (tag, splice): New EREs. Do not allow NUL or newline in tags.
629 Use {splice} wherever C allows backslash-newline.
630 YY_STEP after space, newline, vertical-tab.
631 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
632
633 (letter, id): Don't assume ASCII; e.g., spell out a-z.
634
635 ({int}, handle_action_dollar, handle_action_at): Check for integer
636 overflow.
637
638 (YY_STEP): Omit trailing semicolon, so that it's more like C.
639
640 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
641 as well as \000. Check for UCHAR_MAX, not 255.
642 Allow \x with an arbitrary positive number of digits, as in C.
643 Check for overflow here.
644 Allow \? and UCNs, for compatibility with C.
645
646 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
647 with quote slot used by complain_at.
648
649 * tests/input.at: Add tests for backslash-newline, m4 quotes
650 in symbols, long literals, and funny escapes in strings.
651
652 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
653 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
654 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
655 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
656 * m4/mbswidth.m4: New file, from GNU coreutils.
657
658 * doc/bison.texinfo (Grammar Outline): Document // comments.
659 (Symbols): Document that trigraphs have no special meaning in Bison,
660 nor is backslash-newline allowed.
661 (Actions): Document that trigraphs have no special meaning.
662
663 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
664 no longer used.
665
666 2002-11-02 Paul Eggert <eggert@twinsun.com>
667
668 * src/reader.c: Don't include quote.h; not needed.
669 (get_merge_function): Reword warning to be consistent with
670 type clash diagnostic in grammar_current_rule_check.
671
672 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
673 bug in trigraph handling.
674
675 * src/output.c (prepare_symbols): When printing token names,
676 escape "[" as "@<:@" and likewise for "]".
677
678 * src/system.h (errno): Remove declaration, as we are now
679 assuming C89 or better, and C89 guarantees errno.
680
681 2002-10-30 Paul Eggert <eggert@twinsun.com>
682
683 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
684 Check for close failures.
685 * src/files.h (xfclose): Return void, not int, since it always
686 returned zero.
687 * src/files.c (xfclose): Likewise. Report I/O error if ferror
688 indicates one.
689 * src/output.c (output_skeleton): Use xfclose rather than fclose
690 and ferror. xfclose now checks ferror.
691
692 * data/glr.c (YYLEFTMOST_STATE): Remove.
693 (yyreportTree): Use a stack-based leftmost state. This avoids
694 our continuing battles with bogus warnings about initializers.
695
696 2002-10-30 Akim Demaille <akim@epita.fr>
697
698 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
699 #if.
700
701 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
702
703 * tests/glr-regr1.at: New test for reported regressions.
704 * tests/testsuite.at: Add glr-regr1.at test.
705 * tests/Makefile.am: Add glr-regr1.at test.
706
707 2002-10-24 Paul Eggert <eggert@twinsun.com>
708
709 Version 1.75a.
710
711 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
712 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
713 we use malloc. Don't assume 'A' through 'Z' are contiguous.
714 Don't assume strdup exists; POSIX says its an XSI extension.
715 Check for buffer overflow on input.
716
717 2002-10-24 Akim Demaille <akim@epita.fr>
718
719 * src/output.c (output_skeleton): Don't disable M4sugar comments
720 too soon: it results in comments being expanded.
721 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
722 first output.
723
724 2002-10-24 Akim Demaille <akim@epita.fr>
725
726 * data/yacc.c (m4_int_type): New.
727 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
728 char' as only yacc.c wants K&R portability.
729 * data/glr.c (yysigned_char): Remove.
730 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
731 Reported by Quoc Peyrot.
732
733 2002-10-23 Paul Eggert <eggert@twinsun.com>
734
735 * src/main.c (main): With --trace=time, report times even if a
736 non-fatal error occurs. Formerly, the times were reported in some
737 such cases but not in others.
738 * src/reader.c (reader): Just return if a complaint has been issued,
739 instead of exiting, so that 'main' can report times.
740
741 2002-10-22 Akim Demaille <akim@epita.fr>
742
743 * src/system.h: Include sys/types.
744 Reported by Bert Deknuydt.
745
746 2002-10-23 Paul Eggert <eggert@twinsun.com>
747
748 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
749 Suggested by Art Haas.
750
751 2002-10-22 Paul Eggert <eggert@twinsun.com>
752
753 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
754 decl; not needed any more.
755 * src/main.c (main): Use return to exit, undoing yesterday's change.
756 The last OS that we could find where this wouldn't work is
757 SunOS 3.5, and that's too old to worry about now.
758
759 * data/glr.c (struct yyltype): Define members even when not
760 doing locations. This is more consistent with yacc.c, and it
761 works around the following bug reports:
762 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
763 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
764 and I hope it also fixes this bug report:
765 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
766
767 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
768 @acronym consistently. Standardize on "Yacc" instead of "YACC",
769 "Algol" instead of "ALGOL". Give a bit more history about BNF.
770
771 2002-10-22 Akim Demaille <akim@epita.fr>
772
773 * data/README: New.
774
775 2002-10-21 Paul Eggert <eggert@twinsun.com>
776
777 Be consistent about 'bool'; the old code used an enum in one
778 module and an int in another, and this violates the C standard.
779 * m4/stdbool.m4: New file, from coreutils 4.5.3.
780 * configure.ac (AC_HEADER_STDBOOL): Add.
781 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
782 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
783 * src/symtab.c (hash_compare_symbol_t): Likewise.
784 * src/system.h (bool, false, true): Use a definition consistent
785 with ../lib/hash.c. All uses changed.
786
787 * src/complain.c (warning_issued): Renamed from warn_message_count,
788 so that we needn't worry about integer overflow (!).
789 Now of type bool. All uses changed.
790 (complaint_issued): Renamed from complain_message_count; likewise.
791
792 * src/main.c (main): Use exit to exit with failure.
793
794 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
795 rather than 1 and 0.
796 * src/main.c (main): Likewise.
797 * src/getargs.c (getargs): Likewise.
798 * src/reader.c (reader): Likewise.
799
800 * src/getarg.c (getargs): Remove duplicate code for
801 "Try `bison --help'".
802
803 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
804 What was that "2" for?
805
806 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
807 * src/getargs.c (usage): Likewise.
808
809 * src/getargs.c (getargs): When there are too few operands, report
810 the last one. When there are too many, report the first extra
811 one. This is how diffutils does it.
812
813 2002-10-20 Paul Eggert <eggert@twinsun.com>
814
815 Remove K&R vestiges.
816 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
817 * src/complain.c (VA_START): Remove. Assume prototypes.
818 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
819 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
820 fatal): Assume prototypes.
821 * src/complain.h: Assume prototypes.
822 * src/system.h (PARAMS): Remove.
823 Include <limits.h> unconditionally, since it's guaranteeed even
824 for a freestanding C89 compiler.
825 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
826 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
827
828 2002-10-20 Akim Demaille <akim@epita.fr>
829
830 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
831 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

834 (yyprocessOneStack): Use them.
835 (yy_reduce_print): New.
836 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
837
838 2002-10-20 Akim Demaille <akim@epita.fr>
839
840 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
841 arguments and output `void'.

843 (b4_c_function_def): this.
844 (b4_c_function_decl, b4_c_ansi_function_def)
845 (b4_c_ansi_function_decl): New.
846 Change the interpretation of the arguments: before `int, foo', now
847 `int foo, foo'.
848 * data/yacc.c (yyparse): Prototype and define thanks to these.
849 Adjust b4_c_function_def uses.
850 * data/glr.c (yyparse): Likewise, but ANSI only.
851
852 2002-10-20 Akim Demaille <akim@epita.fr>
853
854 * src/output.c (prepare): Move the definition of `tokens_number',
855 `nterms_number', `undef_token_number', `user_token_number_max'
856 to...
857 (prepare_tokens): Here.

859 (prepare_symbols): this.
860 (prepare): Move the definition of `rules_number' to...
861 (prepare_rules): here.
862 (prepare): Move the definition of `last', `final_state_number',
863 `states_number' to...
864 (prepare_states): here.
865 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
866
867 2002-10-20 Akim Demaille <akim@epita.fr>
868
869 * src/tables.h, src/tables.c, src/output.c: Comment changes.
870
871 2002-10-20 Akim Demaille <akim@epita.fr>
872
873 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
874 * data/c.m4: here.
875
876 2002-10-20 Akim Demaille <akim@epita.fr>
877
878 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
879 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
880 `pair'.
881 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
882 `name' to...
883 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
884 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
885 These.
886
887 2002-10-19 Paul Eggert <eggert@twinsun.com>
888
889 Do not create a temporary file, as that involves security and
890 cleanup headaches. Instead, use a pair of pipes.
891 Derived from a suggestion by Florian Krohm.
892 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
893 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

902 (scan_skel): New decl.
903 (output_skeleton): Use pipe rather than temporary file for m4 input.
904 Check that m4sugar.m4 is readable, to avoid deadlock.
905 Check for pipe I/O error.
906 * src/scan-skel.l (readpipe): Remove decl.
907 (scan_skel): New function, to be used in place of m4_invoke.
908 Read from stream rather than file.
909
910 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
911 float, as this generates a warning on Solaris 8 + GCC 3.2 with
912 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
913 this generates a more-accurate value anyway.
914
915 * lib/timevar.c (timervar_accumulate): Rename locals to
916 avoid confusion with similarly-named more-global.
917 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
918
919 * src/output.c (prepare): Use xstrdup to convert char const *
920 to char *, to avoid GCC warning.
921
922 2002-10-19 Akim Demaille <akim@epita.fr>
923
924 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
925 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
926 Use them to have `calc.y' ready for %pure-parser.
927 * data/yacc.c (YYLEX): Pass a yylex return type to
928 b4_c_function_call.
929
930 2002-10-19 Akim Demaille <akim@epita.fr>
931
932 Prototype support of %lex-param and %parse-param.
933
934 * src/parse-gram.y: Add the definition of the %lex-param and
935 %parse-param tokens, plus their rules.
936 Drop the `_' version of %glr-parser.
937 Add the "," token.
938 * src/scan-gram.l (INITIAL): Scan them.
939 * src/muscle_tab.c: Comment changes.
940 (muscle_insert, muscle_find): Rename `pair' as `probe'.
941 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
942 (muscle_entry_s): The `value' member is no longer const.
943 Adjust all dependencies.
944 * src/muscle_tab.c (muscle_init): Adjust: use
945 MUSCLE_INSERT_STRING.
946 Initialize the obstack earlier.
947 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
948 (muscle_pair_list_grow): New.
949 * data/c.m4 (b4_c_function_call, b4_c_args): New.
950 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
951 * tests/calc.at: Use %locations, not --locations.
952 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
953
954 2002-10-19 Akim Demaille <akim@epita.fr>
955
956 * src/getargs.c (usage): Take status as argument and exit
957 accordingly.
958 Report the traditional `Try ... --help' message when status != 0.
959 (usage, version): Don't take a FILE * as arg, it is pointless.
960 (getargs): When there is an incorrect number of arguments, make it
961 an error, and report it GNUlically thanks to `usage ()'.
962
963 2002-10-18 Paul Eggert <eggert@twinsun.com>
964
965 * data/glr.c (yyreportParseError): Don't assume that sprintf
966 yields the length of the printed string, as this is not true
967 on SunOS 4.1.4. Reported by Peter Klein.
968
969 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
970 * tests/conflicts.at (%nonassoc and eof): Likewise.
971 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
972
973 2002-10-17 Akim Demaille <akim@epita.fr>
974
975 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
976 * src/getargs.c (trace_types, trace_args): Adjust.
977 * src/reader.c (grammar_current_rule_prec_set)
978 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
979 Standardize error messages.
980 And s/@prec/%prec/!
981 (reader): Use trace_flag to enable scanner/parser debugging,
982 instead of an adhoc scheme.
983 * src/scan-gram.l: Remove trailing debugging code.
984
985 2002-10-16 Paul Eggert <eggert@twinsun.com>
986
987 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
988 MUSCLE_TAB_H.
989
990 * NEWS: Officially drop support for building Bison with K&R C,
991 since it didn't work anyway and it's not worth worrying about.
992 * Makefile.maint (wget_files): Remove ansi2knr.c.
993 (ansi2knr.c-url_prefix): Remove.
994 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
995 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
996 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
997
998 2002-10-15 Paul Eggert <eggert@twinsun.com>
999
1000 Stop using the "enum_" trick for K&R-style function definitions;
1001 it confused me, and I was the author! Instead, assume that people
1002 who want to use K&R C compilers (when using these modules in GCC,
1003 perhaps?) will run ansi2knr.
1004
1005 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
1006 All uses of "enum_" changed to "enum ".
1007 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
1008 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
1009
1010 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

1018 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
1019 Use function prototypes; this removes the need for declaring
1020 static functions simply to provide their prototypes.
1021 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

1074 2002-10-14 Akim Demaille <akim@epita.fr>
1075
1076 Version 1.75.
1077
1078 2002-10-14 Akim Demaille <akim@epita.fr>
1079
1080 * tests/Makefile.am (maintainer-check-posix): New.
1081
1082 2002-10-14 Akim Demaille <akim@epita.fr>
1083
1084 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
1085 member.
1086
1087 2002-10-14 Akim Demaille <akim@epita.fr>
1088
1089 * src/tables.c (table_ninf_remap): base -> tab.
1090 Reported by Matt Rosing.
1091
1092 2002-10-14 Paul Eggert <eggert@twinsun.com>
1093
1094 * tests/action.at, tests/calc.at, tests/conflicts.at,
1095 tests/cxx-type.at, tests/headers.at, tests/input.at,
1096 tests/regression.at, tests/synclines.at, tests/torture.at:
1097 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
1098 so that the tests still work even if POSIXLY_CORRECT is set.
1099 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
1100
1101 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
1102 for portability to K&R hosts. Fix typo: signed char is guaranteed
1103 only to 127, not to 128.
1104 * data/glr.c (yysigned_char): New type.
1105 * data/yacc.c (yysigned_char): Likewise.
1106 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
1107
1108 2002-10-13 Paul Eggert <eggert@twinsun.com>
1109
1110 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
1111 true due to limited range of data type" warning from GCC.
1112
1113 * data/c.m4 (b4_token_defines): Protect against double-inclusion
1114 by wrapping enum yytokentype's definition inside #ifndef
1115 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
1116
1117 2002-10-13 Akim Demaille <akim@epita.fr>
1118
1119 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
1120 Un yy- yyrhs to avoid the name clash with the global YYRHS.
1121
1122 2002-10-13 Akim Demaille <akim@epita.fr>
1123
1124 * Makefile.maint: Update from Autoconf 2.54.
1125 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
1126
1127 2002-10-13 Akim Demaille <akim@epita.fr>
1128
1129 * src/print.c (print_state): Separate the list of solved conflicts
1130 from the other items.
1131 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
1132
1133 2002-10-13 Akim Demaille <akim@epita.fr>
1134
1135 Let nondeterministic skeletons be usable with deterministic
1136 tables.
1137
1138 With the patch, GAWK compiled by GCC without -O2 passes its test
1139 suite using a GLR parser driven by LALR tables. It fails with -O2
1140 because `struct stat' gives two different answers on my machine:
1141 88 (definition of an auto var) and later 96 (memset on this var).
1142 Hence the stack is badly corrumpted. The headers inclusion is to
1143 blame: if I move the awk.h inclusion before GLR's system header
1144 inclusion, the two struct stat have the same size.
1145
1146 * src/tables.c (pack_table): Always create conflict_table.
1147 (token_actions): Always create conflict_list.
1148 * data/glr.c (YYFLAG): Remove, unused.
1149
1150 2002-10-13 Akim Demaille <akim@epita.fr>
1151
1152 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
1153 (O0FLAGS): New.
1154 (VALGRIND, GXX): New.
1155 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
1156 * tests/bison.in: Run $PREBISON a pre-command.
1157 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
1158 (maintainer-check-g++): New.
1159 * Makefile.am (maintainer-check): New.
1160
1161 2002-10-13 Akim Demaille <akim@epita.fr>
1162
1163 * data/glr.c: Formatting changes.
1164 Tweak some trace messages to match yacc.c's.
1165
1166 2002-10-13 Akim Demaille <akim@epita.fr>
1167
1168 GLR parsers sometimes raise parse errors instead of performing the
1169 default reduction.
1170 Reported by Charles-Henry de Boysson.
1171
1172 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
1173 check the length of the traces when %glr.
1174 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
1175 GLR's traces.
1176 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
1177 Test GLR parsers.
1178 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
1179 (yyltype): Remove the yy prefix from the member names.
1180 (yytable): Complete its comment.
1181 (yygetLRActions): Map error action number from YYTABLE from
1182 YYTABLE_NINF to 0.
1183 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
1184 (which was a bug: it should have been YYTABEL_NINF, and yet it was
1185 not satisfying as we could compare an YYACTION computed from
1186 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
1187 only value for error actions.
1188 (yyreportParseError): In verbose parse error messages, don't issue
1189 `error' in the list of expected tokens.
1190 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
1191 next action to perform to match glr.c's decoding.
1192 (yytable): Complete its comment.
1193
1194 2002-10-13 Paul Eggert <eggert@twinsun.com>
1195
1196 Fix problem reported by Henrik Grubbstroem in
1197 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
1198 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
1199 because the Bison parser reads the second action before reducing
1200 the first one.
1201 * src/scan-gram.l (rule_length): New static var.
1202 Use it to keep track of the rule length in the scanner, since
1203 we can't expect the parser to be in lock-step sync with the scanner.
1204 (handle_action_dollar, handle_action_at): Use this var.
1205 * tests/actions.at (Exotic Dollars): Test for the problem.
1206
1207 2002-10-12 Paul Eggert <eggert@twinsun.com>
1208
1209 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
1210 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
1211 Include <sys/time.h> when checking for clock_t and struct tms.
1212 Use same include order as source.
1213 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
1214 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>.
1215
1216 * lib/timevar.c: Update copyright date and clarify comments.
1217 (get_time) [IN_GCC]: Keep the GCC version for reference.
1218
1219 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
1220 GCC version as of today, then merge Bison's changes.
1221 Change "GCC" to "Bison" in copyright notice. timevar.def's
1222 author is Akim, so change that too.
1223
1224 * src/reader.c (grammar_current_rule_check):
1225 Don't worry about the default action if $$ is untyped.
1226 Prevents bogus warnings reported by Jim Gifford in
1227 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>.
1228
1229 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
1230 * data/glr.c, data/lalr1.cc, data/yacc.c:
1231 Output token definitions before the first part of user declarations.
1232 Fixes compatibility problem reported by Jim Gifford for kbd in
1233 <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>.
1234
1235 2002-10-11 Paul Eggert <eggert@twinsun.com>
1236
1237 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
1238 (yyparse): here. This undoes some of the 2002-07-25 change.
1239 Compatibility problem reported by Ralf S. Engelschall with
1240 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
1241
1242 2002-10-11 Akim Demaille <akim@epita.fr>
1243
1244 * tests/regression.at Characters Escapes): New.

1246 characters.
1247 Reported by Jan Nieuwenhuizen.
1248
1249 2002-10-11 Akim Demaille <akim@epita.fr>

1253 2002-10-10 Paul Eggert <eggert@twinsun.com>
1254
1255 Portability fixes for bitsets; this also avoids several GCC
1256 warnings.
1257
1258 * lib/abitset.c: Include <stddef.h>, for offsetof.
1259 * lib/lbitset.c: Likewise.
1260
1261 * lib/abitset.c (abitset_bytes): Return a size that is aligned
1262 properly for vectors of objects. Do not assume that adding a
1263 header size to a multiple of a word size yields a value that is
1264 properly aligned for the whole union.
1265 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1266
1267 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,

1289 bitset_stats_andn_or_cmp, bitset_stats_or_and,
1290 bitset_stats_or_and_cmp): Likewise.
1291 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,

1298 * lib/lbitset.h: Likewise.
1299
1300 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
1301 All instances of parameters of type enum bitset_opts are now of
1302 type enum_bitset_opts, to conform to the C Standard, and similarly
1303 for enum_bitset_type.
1304 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
1305 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
1306
1307 Do not use "struct bitset_struct" to mean different things in
1308 different modules. Not only is this confusing, it violates
1309 the C Standard, which requires that structure types in different
1310 modules must be compatible if one is to be passed to the other.
1311 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
1312 All instances of "struct bitset_struct *" replaced with "bitset".
1313 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
1314 (union bitset_union, struct abitset_struct, struct ebitset_struct,
1315 struct lbitset_struct, struct bitset_stats_struct): New types.
1316 All uses of struct bitset_struct changed to union bitset_union,
1317 etc.

1323 bitset_struct): Remove.
1324 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
1325 Likewise.
1326
1327 Do not call a function of type T using a call that assumes the
1328 function is of a different type U. Standard C requires that a
1329 function must be called with a type that is compatible with its
1330 definition.
1331 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
1332 New decls.
1333 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
1334 New functions.
1335 * lib/ebitset.c (PFV): Remove.

1338 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
1339 decls.
1340 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
1341 (ebitset_vtable): Use them.
1342 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
1343 lbitset_xor): New functions.
1344 (lbitset_vtable): Use them.
1345
1346 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
1347 Declare.
1348
1349 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
1350 GCC warning.
1351 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
1352 Use offsetof, for simplicity.
1353
1354 2002-10-06 Paul Eggert <eggert@twinsun.com>
1355
1356 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
1357 the same width as int. This reapplies a hunk of the 2002-08-12 patch
1358 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
1359 which was inadvertently undone by the 2002-09-30 patch.
1360 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
1361 the same width as int.

1368
1369 * doc/bison.texinfo: Minor spelling, grammar, and white space
1370 fixes.
1371 (Symbols): Mention that any negative value returned from yylex
1372 signifies end-of-input. Warn about negative chars. Mention
1373 the portable Standard C character set.
1374
1375 The GNU coding standard says CFLAGS and YFLAGS are reserved
1376 for the installer to set.
1377 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
1378 * src/Makefile.am (AM_CFLAGS): Likewise.
1379 (AM_YFLAGS): Renamed from YFLAGS.
1380
1381 Fix some MAX and MIN problems.

1385 * src/reader.c (reader): Use it.
1386

1442 abitset_or_and, abitset_or_and_cmp):
1443 Use bitset_windex instead of unsigned int.
1444 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
1445 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,

1460 BITSET_SIZE_MAX): New macros.
1461 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
1462 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
1463 to BITSET_WINDEX_MAX.
1464
1465 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
1466 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

1620 (yypstates): Do not assume that ptrdiff_t is the same width
1621 as int, and similarly for yyposn and YYINDEX.

1664 check for void *.
1665
1666 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
1667 size_t; the old version tried to do this but casted improperly.
1668 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.

1693 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
1694 * m4/mbstate_t.m4: Sync with fileutils.
1695 * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
1696
1697 * po/LINGUAS: Add pt_BR.
1698 * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
1699 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
1700 lib/timevar.c.
1701 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
1702 manual recommends.
1703 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
1704
1705 * src/complain.c (strerror_r): Remove decl; not needed.
1706 (strerror): Use same pattern as ../lib/error.c.

1712 * src/main.c (main): Cast result of bindtextdomain and textdomain
1713 to void, to avoid a GCC warning when --disable-nls is in effect.
1714
1715 * src/scan-gram.l: Use strings rather than escapes when possible,
1716 to minimize the number of warnings from xgettext.
1717 (handle_action_dollar, handle_action_at): Don't use isdigit,
1718 as it mishandles negative chars and it may not work as expected
1719 outside the C locale.
1720
1721 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
1722 this is a GCC extension and is not portable to other compilers.
1723
1724 * src/system.h (alloca): Use same pattern as ../lib/error.c.
1725 Do not include <ctype.h>; no longer needed.
1726 Do not include <malloc.h>; no longer needed (and generates
1727 warnings on OpenBSD 3.0).
1728
1729 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
1730 it's not portable.
1731
1732 * tests/regression.at: Do not use 'cc -c input.c -o input';
1733 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
1734
1735 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
1736 exit status as failure, not just exit status 1. Sun C exits
1737 with status 2 sometimes.

1740 Use it for the two large tests.
1741

1743
1744 * src/conflicts.c (conflicts_output): Don't output rules never
1745 reduced here, since anyway that computation doesn't work.

1747 (rule_useless_p, rule_never_reduced_p): New.

1753 reduced to...
1754 (token_actions): here.
1755 * src/main.c (main): Make the parser before making the report, so
1756 that rules never reduced are computed.
1757 Call grammar_rules_never_reduced_report.
1758 * src/print.c (print_results): Report rules never reduced.
1759 * tests/conflicts.at, tests/reduce.at: Adjust.
1760
1761 2002-08-01 Akim Demaille <akim@epita.fr>
1762

1767 `lookaheads_rule' member.
1768 (reductions_t): Add a `lookaheads' member.
1769 Use a regular array for the `rules'.

1792 Adjust all dependencies.
1793 * src/nullable.c (set_nullable, free_nullable): Rename as...
1794 (nullable_compute, nullable_free): these.
1795 (rule_list_t): Store rule_t *, not rule_number_t.
1796 * src/state.c (state_rule_lookaheads_print): Directly compare rule
1797 pointers, instead of their numbers.
1798 * src/main.c (main): Call nullable_free, and derives_free earlier,
1799 as they were lo longer used.
1800
1801 2002-08-01 Akim Demaille <akim@epita.fr>
1802
1803 * lib/timevar.c (get_time): Include children time.
1804 * src/lalr.h (LA, LArule): Don't export them: used with the
1805 state_t.
1806 * src/lalr.c (LA, LArule): Static.
1807 * src/lalr.h, src/lalr.c (lalr_free): New.

1810 table_size, not >.
1811 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
1812 (tables_generate): do it, since that's also it which allocates
1813 them.
1814 Don't free LA and LArule, main does.
1815
1816 2002-07-31 Akim Demaille <akim@epita.fr>

1831 (goto_actions, sort_actions, matching_state, pack_vector)
1832 (table_ninf_remap, pack_table, prepare_actions): Move to...

1854 * src/main.c (stage): Remove.
1855 (main): Replace `stage' invocations with timevar calls.
1856 * src/output.c: Insert pertinent timevar calls.

1881 expected token.
1882 * tests/actions.at (Printers and Destructors): Adjust.
1883 * tests/calc.at (Calculator $1): Adjust.
1884 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
1885 error message, do not report the parser accepts the error token in
1886 that state.

1901 by conflicts.
1902
1903 * src/LR0.c (save_reductions): Don't make the final state too
1904 different: save its reduction (accept) instead of having a state
1905 without any action (no shift or goto, no reduce).
1906 Note: the final state is now a ``regular'' state, i.e., the
1907 parsers now contain `reduce 0' as default reduction.
1908 Nevertheless, since they decide to `accept' when yystate =
1909 final_state, they still will not reduce rule 0.

1952 2002-07-26 Akim Demaille <akim@epita.fr>
1953
1954 * src/reader.h, src/reader.c (gram_error): ... can't get
1955 yycontrol without making too strong assumptions on the parser
1956 itself.
1957 * src/output.c (prepare_tokens): Use the real 0th value of
1958 token_translations instead of `0'.
1959 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1960 visible here.
1961 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1962 for the time being: %locations ought to provide it to yyerror.
1963
1964 2002-07-25 Akim Demaille <akim@epita.fr>
1965
1966 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

1975 * src/nullable.c, src/output.c, src/print.c, src/reader.c
1976 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
1977 Iterate from 0 to nrules.
1978 Use rule_number_as_item_number and item_number_as_rule_number.
1979 Adjust to `derive' now containing possibly 0.
1980 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
1981 Handle the `- 1' part in rule numbers from/to item numbers.

3003 * src/parse-gram.y: Use it.
3004

3006 defined, then default to int, or to the contents of %union,
3007 without `union' itself.
3008 Adjust.
3009 * src/muscle_tab.c (muscle_init): Don't predefine `stype'.
3010
3011 * src/output.c (actions_output): Don't output braces, as they are

3030 * src/scan-gram.l: Working properly with escapes in user

3034 (AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'
3035 grammar.
3036 Use more modest sizes, as for the time being the parser does not

3040 * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the
3041 stricter %token grammar.

3063 * src/reader.c (parse_action): Don't store directly into the

3087 * src/reader.c (grammar_rule_begin, previous_rule, current_rule):
3088 New.
3089 (readgram): Use them as replacement of inlined code, crule and
3090 crule1.

3111 assigning twice the same user number to a token, so that we can
3112 use it in...
3113 * src/lex.c (lex): here.
3114 Also use `symbol_class_set' instead of hand written code.
3115 * src/reader.c (parse_assoc_decl): Likewise.

3126
3127 Remove `%thong' support as it is undocumented, unused, duplicates
3128 `%token's job, and creates useless e-mail traffic with people who
3129 want to know what it is, why it is undocumented, unused, and
3130 duplicates `%token's job.
3131
3132 * src/reader.c (parse_thong_decl): Remove.

3501 (parse_guard): Rename the formal argument `stack_offset' as
3502 `rule_length', which is more readable.
3503 Adjust callers.
3504 (copy_at, copy_dollar): Instead of outputting the hard coded
3505 values of $$, $n and so forth, output invocation to b4_lhs_value,
3506 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
3507 Note: this patch partially drops `semantic-parser' support: it
3508 always does `rule_length - n', where semantic parsers ought to
3509 always use `-n'.

3614 2002-04-22 Akim Demaille <akim@epita.fr>
3615
3616 * src/reader.c (token_translations_init): 256 is now the default
3617 value for the error token, i.e., it will be assigned another
3618 number if the user assigned 256 to one of her tokens.

3620 * doc/bison.texinfo (Symbols): Adjust.
3621 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
3622 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
3623 etc. instead of 10, 20, 30 (which was used to `jump' over error
3624 (256) and undefined (2)).
3625

3659 Suggested by Paul Eggert.
3660
3661 2002-04-09 Akim Demaille <akim@epita.fr>
3662
3663 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
3664 full stderr, and strip it according to the bison options, instead
3665 of composing the error message from different bits.
3666 This makes it easier to check for several error messages.
3667 Adjust all the invocations.
3668 Add an invocation exercising the error token.
3669 Add an invocation demonstrating a stupid error message.
3670 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

3681 * src/symtab.h: here.
3682 (state_t.number): Is a token_number_t.
3683 * src/print.c, src/reader.c: Use undeftoken->number instead of
3684 hard coded 2.
3685 (Even though this 2 is not the same as above: the number of the
3686 undeftoken remains being 2, it is its user token number which
3687 might not be 2).
3688 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
3689 `user_token_number_max'.
3690 Output `undef_token_number'.
3691 * data/bison.simple, data/bison.c++: Use them.
3692 Be sure to map invalid yylex return values to
3693 `undef_token_number'. This saves us from gratuitous SEGV.

3712 RITEM. Note that it must be able to code symbol numbers as
3713 positive number, and the negation of rule numbers as negative
3714 numbers.
3715 Adjust all dependencies (pretty many).
3716 * src/reduce.c (rule): Remove this `short *' pointer: use
3717 item_number_t.
3718 * src/system.h (MINSHORT, MAXSHORT): Remove.
3719 Include `limits.h'.
3720 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

3727 500.
3728 * tests/regression.at (Web2c Actions): Ajust.
3729
3730 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
3731 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
3732 passes, but produces negative #line number, once fixed, GCC is
3733 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
3734 C), it passes.
3735 * src/state.h (state_h): Code input lines on ints, not shorts.
3736
3737 2002-04-08 Akim Demaille <akim@epita.fr>

3880 in the output if you don't need it.
3881
3882 2002-04-07 Akim Demaille <akim@epita.fr>
3883
3884 * src/LR0.c (new_state): Display `nstates' as the name of the

3886 Adjust to initialize first_state and last_state if needed.
3887 Be sure to distinguish the initial from the final state.
3888 (new_states): Create the itemset of the initial state, and use
3889 new_state.
3890 * src/closure.c (closure): Now that the initial state has its
3891 items properly set, there is no need for a special case when
3892 creating `ruleset'.
3893
3894 As a result, now the rule 0, reducing to $axiom, is visible in the
3895 outputs. Adjust the test suite.
3896
3897 * tests/conflicts.at (Solved SR Conflicts)
3898 (Unresolved SR Conflicts): Adjust.

3927 the end of `rules', and count them out of `nrules'.
3928 (reduce_output, dump_grammar): Adjust.

3933 2002-04-07 Akim Demaille <akim@epita.fr>
3934

3936 lacking `+ 1' to nrules, Bison reported as useless a token if it
3937 was used solely to set the precedence of the last rule...
3938
3939 2002-04-07 Akim Demaille <akim@epita.fr>
3940
3941 * data/bison.c++, data/bison.simple: Don't output the current file
3942 name in #line, to avoid useless diffs between two identical
3943 outputs under different names.
3944
3945 2002-04-07 Akim Demaille <akim@epita.fr>
3946
3947 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

3962 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,

4327 * src/output.c (actions_output, guards_output)
4328 (token_definitions_output): No longer keeps track of the output
4329 line number, hence remove the second argument.
4330 (guards_output): Check against the guard member of a rule, not the
4331 action member.
4332 Adjust callers.
4333 (output_skeleton): Don't look for the skeleton location, let m4 do
4334 that.
4335 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
4336 file will be used.
4337 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
4338 (prepare): Given that for the time being changesyntax is not
4339 usable in M4, rename the muscles using `-' to `_'.
4340 Define `defines_flag', `output_parser_name' and `output_header_name'.
4341 * src/output.h (actions_output, guards_output)
4342 (token_definitions_output): Adjust prototypes.
4343 * src/scan-skel.l: Instead of scanning the skeletons, it now
4344 processes the output of m4: `__oline__' and `#output'.
4345 * data/bison.simple: Adjust to be used by M4(sugar).
4346 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
4347 to date.
4348 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
4349 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
4350 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
4351 shamelessly stolen from CVS Autoconf.
4352
4353 2002-02-05 Akim Demaille <akim@epita.fr>
4354
4355 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
4356 * configure.in: Check for the declarations of free and malloc.
4357 * src/muscle_tab.c: Adjust.
4358
4359 2002-02-05 Akim Demaille <akim@epita.fr>
4360
4361 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
4362 which have no values.
4363
4364 2002-02-05 Akim Demaille <akim@epita.fr>
4365
4366 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
4367 * data/: here.
4368
4369 2002-01-29 Paul Eggert <eggert@twinsun.com>
4370
4371 * src/bison.simple (YYSIZE_T): Do not define merely because
4372 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
4373 On some platforms, <alloca.h> does not declare YYSTD (size_t).
4374
4375 2002-01-27 Akim Demaille <akim@epita.fr>
4376
4377 Fix `%nonassoc and eof'.
4378
4379 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
4380 which were not properly copied! Replace
4381 memcpy (res->errs, src->errs, src->nerrs);
4382 with
4383 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
4384 !!!
4385 * tests/regression.at (%nonassoc and eof): Adjust to newest
4386 Autotest: `.' is not in the PATH.
4387
4388 2002-01-27 Akim Demaille <akim@epita.fr>
4389
4390 * tests/sets.at (AT_EXTRACT_SETS): New.
4391 (Nullable): Use it.
4392 (Firsts): New.
4393
4394 2002-01-26 Akim Demaille <akim@epita.fr>
4395
4396 * tests/actions.at, tests/calc.at, tests/headers.at,
4397 * tests/torture.at: Adjust to the newest Autotest which no longer
4398 forces `.' in the PATH.
4399
4400 2002-01-25 Akim Demaille <akim@epita.fr>
4401
4402 * tests/regression.at (%nonassoc and eof): New.
4403 Suggested by Robert Anisko.
4404
4405 2002-01-24 Akim Demaille <akim@epita.fr>
4406
4407 Bison dumps core when trying to complain about broken input files.
4408 Reported by Cris van Pelt.
4409
4410 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
4411 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
4412 into...
4413 (Invalid inputs): Strengthen: exercise parse_percent_token.
4414
4415 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
4416
4417 * src/Makefile.am: Add bison.c++.
4418 * src/bison.c++: New skeleton.
4419
4420 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
4421
4422 * po/it.po: New.
4423
4424 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
4425
4426 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
4427
4428 2002-01-20 Marc Autret <marc@gnu.org>
4429
4430 * src/files.c (compute_output_file_names): Fix
4431
4432 2002-01-20 Marc Autret <marc@gnu.org>
4433
4434 * tests/output.at: New test.
4435 * src/files.c (compute_base_names): Don't map extensions when
4436 the YACC flag is set, use defaults.
4437 Reported by Evgeny Stambulchik.
4438
4439 2002-01-20 Marc Autret <marc@gnu.org>
4440
4441 * src/system.h: Need to define __attribute__ away for non-GCC
4442 compilers as well (i.e. the vendor C compiler).
4443 Suggested by Albert Chin-A-Young.
4444
4445 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
4446
4447 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
4448 canonical definition.
4449 * src/system.h: Use the canonical definition for PARAMS (avoids
4450 a conflict with the macro from lib/hash.h).
4451
4452 2002-01-11 Akim Demaille <akim@epita.fr>
4453
4454 * configure.in: Use AC_FUNC_STRNLEN.
4455 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
4456
4457 2002-01-09 Akim Demaille <akim@epita.fr>
4458
4459 * src/files.c, src/files.h (output_infix): New.
4460 (tab_extension): Remove.
4461 (compute_base_names): Compute the former, drop the latter.
4462 * src/output.c (prepare): Insert the muscles `output-infix', and
4463 `output-suffix'.
4464 * src/parse-skel.y (string, string.1): New.
4465 (section.header): Use it.
4466 (section.yacc): Remove.
4467 (prefix): Remove too.
4468 * src/scan-skel.l: Adjust.
4469 * src/bison.simple, src/bison.hairy: Adjust.
4470
4471 2002-01-09 Akim Demaille <akim@epita.fr>
4472
4473 * configure.in (WERROR_CFLAGS): Compute it.
4474 * src/Makefile.am (CFLAGS): Pass it.
4475 * tests/atlocal.in (CFLAGS): Idem.
4476 * src/files.c: Fix a few warnings.
4477 (get_extension_index): Remove, unused.
4478
4479 2002-01-08 Akim Demaille <akim@epita.fr>
4480
4481 * src/getargs.c (AS_FILE_NAME): New.
4482 (getargs): Use it to convert DOSish file names.
4483 * src/files.c (base_name): Rename as full_base_name to avoid
4484 clashes with `base_name ()'.
4485 (filename_split): New.
4486 (compute_base_names): N-th rewrite, using filename_split.
4487
4488 2002-01-08 Akim Demaille <akim@epita.fr>
4489
4490 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
4491 New, stolen from the Fileutils 4.1.
4492 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
4493 * configure.in: Check for the presence of memrchr, and of its
4494 prototype.
4495
4496 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
4497
4498 * lib/hash.h (__P): Added definition for this macro.
4499 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
4500 BUILT_SOURCES, to ensure they are generated first.
4501 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
4502 %error-verbose to allow bootstrapping with bison 1.30x.
4503
4504 2002-01-06 Akim Demaille <akim@epita.fr>
4505
4506 * src/reader.c (parse_braces): Don't fetch the next char, the
4507 convention is to fetch on entry.
4508 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
4509 'switch' without a following semicolon.
4510 * tests/regression.at (braces parsing): New.
4511
4512 2002-01-06 Akim Demaille <akim@epita.fr>
4513
4514 Bison is dead wrong in its RR conflict reports.
4515
4516 * tests/torture.at (GNU Cim Grammar): New.
4517 * src/conflicts.c (count_rr_conflicts): Fix.
4518
4519 2002-01-06 Akim Demaille <akim@epita.fr>
4520
4521 Creating package.m4 from configure.ac causes too many problems.
4522
4523 * tests/Makefile.am (package.m4): Create it by hand,
4524 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
4525
4526 2002-01-06 Akim Demaille <akim@epita.fr>
4527
4528 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
4529 skeleton.h.
4530
4531 2002-01-04 Paul Eggert <eggert@twinsun.com>
4532
4533 * doc/bison.texinfo (Debugging):
4534 Remove YYSTDERR; it's no longer defined or used.
4535 Also, s/cstdio.h/cstdio/.
4536
4537 2002-01-03 Akim Demaille <akim@epita.fr>
4538
4539 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
4540
4541 2002-01-03 Akim Demaille <akim@epita.fr>
4542
4543 * src/parse-skel.y (process_skeleton): Don't bind the parser's
4544 tracing code to --trace, wait for a better --trace option, with
4545 args.
4546
4547 2002-01-03 Akim Demaille <akim@epita.fr>
4548
4549 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
4550 The ISO C++ standard is extremely clear about it: stderr is
4551 considered a macro, not a regular symbol (see table 94 `Header
4552 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
4553 Therefore std:: does not apply to it. It still does with fprintf.
4554 Also, s/cstdio.h/cstdio/.
4555
4556 2002-01-03 Akim Demaille <akim@epita.fr>
4557
4558 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
4559 for non system headers.
4560
4561 2002-01-02 Akim Demaille <akim@epita.fr>
4562
4563 Equip the skeleton chain with location tracking, runtime trace,
4564 pure parser and scanner.
4565
4566 * src/parse-skel.y: Request a pure parser, locations, and prefix
4567 renaming.
4568 (%union): Having several members with the same type does not help
4569 type mismatches, simplify.
4570 (YYPRINT, yyprint): New.
4571 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
4572 (skel_error): this.
4573 Handle locations.
4574 * src/scan-skel.l: Adjust to these changes.
4575 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
4576 (LOCATION_PRINT, skel_control_t): New.
4577
4578 2001-12-30 Akim Demaille <akim@epita.fr>
4579
4580 * src/parse-skel.y: Get rid of the shift/reduce conflict:
4581 replace `gb' with BLANKS.
4582 * src/scan-skel.l: Adjust.
4583
4584 2001-12-30 Akim Demaille <akim@epita.fr>
4585
4586 * src/system.h: We don't need nor want bcopy.
4587 Throw away MS-DOS crap: we don't need getpid.
4588 * configure.in: We don't need strndup. It was even causing
4589 problems: because Flex includes the headers *before* us,
4590 _GNU_SOURCE is not defined by config.h, and therefore strndup was
4591 not visible.
4592 * lib/xstrndup.c: New.
4593 * src/scan-skel.l: Use it.
4594 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
4595 * src/parse-skel.y: Use %directives instead of #defines.
4596
4597 2001-12-30 Akim Demaille <akim@epita.fr>
4598
4599 * src/skeleton.h: New.
4600 * src/output.c (output_parser, output_master_parser): Remove, dead
4601 code.
4602 * src/output.h (get_lines_number, actions_output, guards_output)
4603 (token_definitions_output): Prototype them.
4604 * src/parse-skel.y: Add the license notice.
4605 Include output.h and skeleton.h.
4606 (process_skeleton): Returns void, and takes a single parameter.
4607 * src/scan-skel.l: Add the license notice.
4608 Include skeleton.h.
4609 Don't use %option yylineno: it seems that then Flex imagines
4610 REJECT has been used, and therefore it won't reallocate its
4611 buffers (which makes no other sense to me than a bug). It results
4612 in warnings for `unused: yy_flex_realloc'.
4613
4614 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
4615
4616 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4617 (MUSCLE_INSERT_PREFIX): ...to there.
4618 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4619 (MUSCLE_INSERT_PREFIX): Move from here...
4620
4621 * src/bison.hairy: Add a section directive. Put braces around muscle
4622 names. This parser skeleton is still broken, but Bison should not
4623 choke on a bad muscle 'syntax'.
4624 * src/bison.simple: Add a section directive. Put braces around muscle
4625 names.
4626
4627 * src/files.h (strsuffix, stringappend): Add declarations.
4628 (tab_extension): Add declaration.
4629 (short_base_name): Add declaration.
4630
4631 * src/files.c (strsuffix, stringappend): No longer static. These
4632 functions are used in the skeleton parser.
4633 (tab_extension): New.
4634 (compute_base_names): Use the computations done in this function
4635 to guess if the generated parsers should have '.tab' in their
4636 names.
4637 (short_base_name): No longer static.
4638
4639 * src/output.c (output_skeleton): New.
4640 (output): Disable call to output_master_parser, and give a try to
4641 a new skeleton handling system.
4642 (guards_output, actions_output): No longer static.
4643 (token_definitions_output, get_lines_number): No longer static.
4644
4645 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
4646
4647 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
4648 parse-skel.y.
4649
4650 * src/parse-skel.y: New file.
4651 * src/scan-skel.l: New file.
4652
4653 2001-12-29 Akim Demaille <akim@epita.fr>
4654
4655 %name-prefix is broken.
4656
4657 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
4658 Adjust all dependencies.
4659 * tests/headers.at (export YYLTYPE): Strengthen this test: use
4660 %name-prefix.
4661
4662 Renaming yylval but not yylloc is not consistent. Now we do.
4663
4664 * src/bison.simple: Prefix yylloc if used.
4665 * doc/bison.texinfo (Decl Summary): Document that.
4666
4667 2001-12-29 Akim Demaille <akim@epita.fr>
4668
4669 * doc/bison.texinfo: Promote `%long-directive' over
4670 `%long_directive'.
4671 Remove all references to fixed-output-files, yacc is enough.
4672
4673 2001-12-29 Akim Demaille <akim@epita.fr>
4674
4675 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4676 user prologue. These are defaults.
4677 * tests/actions.at (Mid-rule actions): Make sure the user can
4678 define YYDEBUG and YYERROR_VERBOSE.
4679
4680 2001-12-29 Akim Demaille <akim@epita.fr>
4681
4682 * src/output.c (header_output): Don't forget to export YYLTYPE and
4683 yylloc.
4684 * tests/headers.at (export YYLTYPE): New, make sure it does.
4685 * tests/regression.at (%union and --defines, Invalid CPP headers):
4686 Move to...
4687 * tests/headers.at: here.
4688
4689 2001-12-29 Akim Demaille <akim@epita.fr>
4690
4691 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
4692
4693 2001-12-29 Akim Demaille <akim@epita.fr>
4694
4695 * tests/actions.at (Mid-rule actions): Output on a single line
4696 instead of several.
4697
4698 2001-12-29 Akim Demaille <akim@epita.fr>
4699
4700 * doc/bison.texinfo: Formatting changes.
4701
4702 2001-12-29 Akim Demaille <akim@epita.fr>
4703
4704 Don't store the token defs in a muscle, just be ready to output it
4705 on command. Now possible via `symbols'. Fixes a memory leak.
4706
4707 * src/output.c (token_definitions_output): New.
4708 (output_parser, header_output): Use it.
4709 * src/reader.c (symbols_save): Remove.
4710
4711 2001-12-29 Akim Demaille <akim@epita.fr>
4712
4713 * src/bison.simple: Do not provide a default for YYSTYPE and
4714 YYLTYPE before the user's prologue. Otherwise it's hardly... a
4715 default.
4716
4717 2001-12-29 Akim Demaille <akim@epita.fr>
4718
4719 Mid-rule actions are simply... ignored!
4720
4721 * src/reader.c (readgram): Be sure to attach mid-rule actions to
4722 the empty-rule associated to the dummy symbol, not to the host
4723 rule.
4724 * tests/actions.at (Mid-rule actions): New.
4725
4726 2001-12-29 Akim Demaille <akim@epita.fr>
4727
4728 Memory leak.
4729
4730 * src/reader.c (reader): Free grammar.
4731
4732 2001-12-29 Akim Demaille <akim@epita.fr>
4733
4734 Memory leak.
4735
4736 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
4737 since it allocates it for each state, although only one is needed.
4738 (allocate_storage): Do it here.
4739
4740 2001-12-29 Akim Demaille <akim@epita.fr>
4741
4742 * src/options.h, src/options.c (create_long_option_table): Rename
4743 as...
4744 (long_option_table_new): this, with a clearer prototype.
4745 (percent_table): Remove, unused,
4746 * src/getargs.c (getargs): Adjust.
4747
4748 2001-12-29 Akim Demaille <akim@epita.fr>
4749
4750 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
4751 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
4752 as states.
4753
4754 2001-12-29 Akim Demaille <akim@epita.fr>
4755
4756 * src/lalr.c (build_relations): Rename `states' as `states1'.
4757 Sorry, I don't understand exactly what it is, no better name...
4758
4759 2001-12-29 Akim Demaille <akim@epita.fr>
4760
4761 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
4762 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
4763 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
4764 as rules.
4765
4766 2001-12-29 Akim Demaille <akim@epita.fr>
4767
4768 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
4769 ago.
4770
4771 2001-12-29 Akim Demaille <akim@epita.fr>
4772
4773 * src/reader.c, src/reader.h (user_toknums): Remove.
4774 Adjust all users to use symbols[i]->user_token_number.
4775
4776 2001-12-29 Akim Demaille <akim@epita.fr>
4777
4778 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
4779 Adjust all users to use symbols[i]->prec or ->assoc.
4780
4781 2001-12-29 Akim Demaille <akim@epita.fr>
4782
4783 * src/reader.c, src/reader.h (tags): Remove.
4784 Adjust all users to use symbols[i]->tag.
4785
4786 2001-12-29 Akim Demaille <akim@epita.fr>
4787
4788 * src/gram.h, src/gram.c (symbols): New, similar to state_table
4789 and rule_table.
4790 * src/reader.c (packsymbols): Fill this table.
4791 Drop sprec.
4792 * src/conflicts.c (resolve_sr_conflict): Adjust.
4793 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
4794 single table.
4795 Use symbols[i]->tag instead of tags[i].
4796
4797 2001-12-29 Akim Demaille <akim@epita.fr>
4798
4799 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
4800 In addition, put a comment in there, to replace...
4801 * tests/regression.at (%union and C comments): Remove.
4802
4803 2001-12-29 Akim Demaille <akim@epita.fr>
4804
4805 * tests/regression.at (Web2c Actions): Blindly move the actual
4806 output as expected output. The contents *seem* right to me, but I
4807 can't pretend reading perfectly parser tables... Nonetheless, all
4808 the other tests pass correctly, the table look OK, even though the
4809 presence of `$axiom' is to be noted: AFAICS it is useless (but
4810 harmless).
4811
4812 2001-12-29 Akim Demaille <akim@epita.fr>
4813
4814 * src/reader.c (readgram): Don't add the rule 0 if there were no
4815 rules read. In other words, add it _after_ having performed
4816 grammar sanity checks.
4817 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
4818
4819 2001-12-29 Akim Demaille <akim@epita.fr>
4820
4821 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
4822 visible, and some states have now a different number.
4823
4824 2001-12-29 Akim Demaille <akim@epita.fr>
4825
4826 * src/reader.c (readgram): Bind the initial rule's lineno to that
4827 of the first rule.
4828 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
4829 (Solved SR Conflicts): Adjust rule 0's line number.
4830
4831 2001-12-29 Akim Demaille <akim@epita.fr>
4832
4833 Fix the `GAWK Grammar' failure.
4834
4835 * src/LR0.c (final_state): Initialize to -1 so that we do compute
4836 the reductions of the first state which was mistakenly confused
4837 with the final state because precisely final_state was initialized
4838 to 0.
4839 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
4840 now noticed by Bison.
4841 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
4842 have a reduction on $default.
4843
4844 2001-12-29 Akim Demaille <akim@epita.fr>
4845
4846 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
4847 rule line numbers.
4848 * src/closure.c (print_closure): Likewise.
4849 * src/derives.c (print_derives): Likewise.
4850 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
4851 now.
4852
4853 2001-12-29 Akim Demaille <akim@epita.fr>
4854
4855 * src/lalr.c (lookaheads_print): New.
4856 (lalr): Call it when --trace-flag.
4857 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
4858 are dumped.
4859
4860 2001-12-29 Akim Demaille <akim@epita.fr>
4861
4862 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
4863 when walking through ritem, even via rule->rhs.
4864 * src/reduce.c (dump_grammar, useful_production, reduce_output)
4865 (useful_production, useless_nonterminals): Likewise.
4866 (reduce_grammar_tables): Likewise, plus update nritems.
4867 * src/nullable.c (set_nullable): Likewise.
4868 * src/lalr.c (build_relations): Likewise.
4869 * tests/sets.at (Nullable): Adjust.
4870 Fortunately, now, the $axiom is no longer nullable.
4871
4872 2001-12-29 Akim Demaille <akim@epita.fr>
4873
4874 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
4875 the 0-sentinel.
4876 * src/gram.c (ritem_longest_rhs): Likewise.
4877 * src/reduce.c (nonterminals_reduce): Likewise.
4878 * src/print_graph.c (print_graph): Likewise.
4879 * src/output.c (output_rule_data): Likewise.
4880 * src/nullable.c (set_nullable): Likewise.
4881
4882 2001-12-29 Akim Demaille <akim@epita.fr>
4883
4884 * src/output.c: Comment changes.
4885
4886 2001-12-27 Paul Eggert <eggert@twinsun.com>
4887
4888 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
4889 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
4890 Sparc, as they were causing more porting problems than the
4891 (minor) performance improvement was worth.
4892
4893 Also, catch up with 1.31's YYSTD.
4894
4895 2001-12-27 Akim Demaille <akim@epita.fr>
4896
4897 * src/output.c (output_gram): Rely on nritems, not the
4898 0-sentinel. See below.
4899 Use -1 as separator, not 0.
4900 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
4901 Rely on -1 as separator in yyrhs, instead of 0.
4902 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
4903 twice `Now at end of input', therefore there are two lines less to
4904 expect.
4905
4906 2001-12-27 Akim Demaille <akim@epita.fr>
4907
4908 * tests/regression.at (Unresolved SR Conflicts):
4909 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
4910 below.
4911
4912 2001-12-27 Akim Demaille <akim@epita.fr>
4913
4914 * src/LR0.c (new_state): Recognize the final state by the fact it
4915 is reached by eoftoken.
4916 (insert_start_shifting_state, insert_eof_shifting_state)
4917 (insert_accepting_state, augment_automaton): Remove, since now
4918 these states are automatically computed from the initial state.
4919 (generate_states): Adjust.
4920 * src/print.c: When reporting a rule number to the user, substract
4921 1, so that the axiom rule is rule 0, and the first user rule is 1.
4922 * src/reduce.c: Likewise.
4923 * src/print_graph.c (print_core): For the time being, just as for
4924 the report, depend upon --trace-flags to dump the full set of
4925 items.
4926 * src/reader.c (readgram): Once the grammar read, insert the rule
4927 0: `$axiom: START-SYMBOL $'.
4928 * tests/set.at: Adjust: rule 0 is now displayed, and since the
4929 number of the states has changed (the final state is no longer
4930 necessarily the last), catch up.
4931
4932 2001-12-27 Akim Demaille <akim@epita.fr>
4933
4934 Try to make the use of the eoftoken valid. Given that its value
4935 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
4936 is used instead of > 0 where appropriate, (ii), depend upon nritems
4937 instead of the 0-sentinel.
4938
4939 * src/gram.h, src/gram.c (nritems): New.
4940 Expected to be duplication of nitems, but for the time being...
4941 * src/reader.c (packgram): Assert nritems and nitems are equal.
4942 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
4943 * src/closure.c (print_closure, print_fderives): Likewise.
4944 * src/gram.c (ritem_print): Likewise.
4945 * src/print.c (print_core, print_grammar): Likewise.
4946 * src/print_graph.c: Likewise.
4947
4948 2001-12-27 Akim Demaille <akim@epita.fr>
4949
4950 * src/main.c (main): If there are complains after grammar
4951 reductions, then output the report anyway if requested, then die.
4952 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
4953 * src/reader.c (eoftoken): New.
4954 (parse_token_decl): If the token being defined has value `0', it
4955 is the eoftoken.
4956 (packsymbols): No longer hack `tags' to insert `$' by hand.
4957 Be sure to preserve the value of the eoftoken.
4958 (reader): Make sure eoftoken is defined.
4959 Initialize nsyms to 0: now eoftoken is created just like the others.
4960 * src/print.c (print_grammar): Don't special case the eof token.
4961 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
4962 lie anyway, albeit pleasant.
4963 * tests/calc.at: Exercise error messages with eoftoken.
4964 Change the grammar so that empty input is invalid.
4965 Adjust expectations.
4966 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
4967
4968 2001-12-27 Akim Demaille <akim@epita.fr>
4969
4970 * configure.in: Check the protos of strchr ans strspn.
4971 Replace strchr if needed.
4972 * src/system.h: Provide the protos of strchr, strspn and memchr if
4973 missing.
4974 * lib/strchr.c: New.
4975 * src/reader.c (symbols_save): Use strchr.
4976
4977 2001-12-27 Akim Demaille <akim@epita.fr>
4978
4979 * src/print.c, src/print_graph.c (escape): New.
4980 Use it to quote the TAGS outputs.
4981 * src/print_graph.c (print_state): Now errors are in red, and
4982 reductions in green.
4983 Prefer high to wide: output the state number on a line of its own.
4984
4985 2001-12-27 Akim Demaille <akim@epita.fr>
4986
4987 * src/state.h, src/state.c (reductions_new): New.
4988 * src/LR0.c (set_state_table): Let all the states have a
4989 `reductions', even if reduced to 0.
4990 (save_reductions): Adjust.
4991 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
4992 * src/print.c (print_reductions, print_actions): Adjust.
4993 * src/output.c (action_row): Adjust.
4994
4995 2001-12-27 Akim Demaille <akim@epita.fr>
4996
4997 * src/state.h, src/state.c (errs_new, errs_dup): New.
4998 * src/LR0.c (set_state_table): Let all the states have an errs,
4999 even if reduced to 0.
5000 * src/print.c (print_errs, print_reductions): Adjust.
5001 * src/output.c (output_actions, action_row): Adjust.

5007
5008 2001-12-27 Akim Demaille <akim@epita.fr>
5009
5010 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
5011 * src/print.c: here.
5012 (lookaheadset, shiftset): New, used as additional storage by
5013 print_reductions.
5014 (print_results): Adjust.
5015 (print_shifts, print_gotos, print_errs): New, extracted from...
5016 (print_actions): here.
5017 * src/print_graph.c (print_actions): Remove dead code.
5018
5019 2001-12-27 Akim Demaille <akim@epita.fr>
5020
5021 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
5022 `$n' and `@n'.
5023
5024 2001-12-27 Akim Demaille <akim@epita.fr>
5025
5026 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
5027 (build_relations): Adjust.
5028
5029 2001-12-27 Akim Demaille <akim@epita.fr>
5030
5031 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
5032 duplication.
5033
5034 2001-12-27 Akim Demaille <akim@epita.fr>
5035
5036 * src/reader.c (packgram): Catch nitems overflows.
5037
5038 2001-12-27 Akim Demaille <akim@epita.fr>
5039
5040 * src/files.c, src/files.h (guard_obstack): Remove.
5041 * src/output.c (output): Adjust.
5042 * src/reader.c (parse_braces): New, factoring...
5043 (copy_action, copy_guard): these two which are renamed as...
5044 (parse_action, parse_guard): these.
5045 As a voluntary consequence, using braces around guards is now
5046 mandatory.
5047
5048 2001-12-27 Akim Demaille <akim@epita.fr>
5049
5050 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
5051 * src/reader.c (symbol_list): `guard' and `guard_line' are new
5052 members.
5053 (symbol_list_new): Adjust.
5054 (copy_action): action_line is the first line, not the last.
5055 (copy_guard): Just as for actions, store the `action' only, not
5056 the switch/case/break flesh.
5057 Don't parse the user action that might follow the guard, let...
5058 (readgram): do it, i.e., now, there can be an action after a
5059 guard.
5060 In other words the guard is just explicitly optional.
5061 (packgram): Adjust.
5062 * src/output.c (guards_output): New.
5063 (output_parser): Call it when needed.
5064 (output): Also free the guard and attrs obstacks.
5065 * src/files.c, src/files.h (obstack_save): Remove.
5066 (output_files): Remove.
5067 As a result, if one needs the former `.act' file, using an
5068 appropriate skeleton which requires actions and guards is now
5069 required.
5070 * src/main.c (main): Adjust.
5071 * tests/semantic.at: New.
5072 * tests/regression.at: Use `input.y' as input file name.
5073 Avoid 8+3 problems by requiring input.c when the test needs the
5074 parser.
5075
5076 2001-12-27 Akim Demaille <akim@epita.fr>
5077
5078 * src/reader.c (symbol_list_new): Be sure to initialize all the
5079 fields.
5080
5081 2001-12-27 Akim Demaille <akim@epita.fr>
5082
5083 All the hacks using a final pseudo state are now useless.
5084
5085 * src/LR0.c (set_state_table): state_table holds exactly nstates.
5086 * src/lalr.c (nLA): New.
5087 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
5088 instead of lookaheadsp from the pseudo state (nstate + 1).
5089
5090 2001-12-27 Akim Demaille <akim@epita.fr>
5091
5092 * src/output.c (action_row, token_actions): Use a state_t instead
5093 of a integer, and nlookaheads instead of the following state's
5094 lookaheadsp.
5095
5096 2001-12-27 Akim Demaille <akim@epita.fr>
5097
5098 * src/conflicts.c (log_resolution, flush_shift)
5099 (resolve_sr_conflict, set_conflicts, solve_conflicts)
5100 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
5101 (conflicts_print, print_reductions): Use a state_t instead of an
5102 integer when referring to a state.
5103 As much as possible, depend upon nlookaheads, instead of the
5104 `lookaheadsp' member of the following state (since lookaheads of
5105 successive states are successive, the difference between state n + 1
5106 and n served as the number of lookaheads for state n).
5107 * src/lalr.c (add_lookback_edge): Likewise.
5108 * src/print.c (print_core, print_actions, print_state)
5109 (print_results): Likewise.
5110 * src/print_graph.c (print_core, print_actions, print_state)
5111 (print_graph): Likewise.

5113
5114 2001-12-27 Akim Demaille <akim@epita.fr>
5115
5116 * src/bison.hairy: Formatting/comment changes.
5117 ANSIfy.
5118 Remove `register' indications.
5119 Add plenty of `static'.
5120
5121 2001-12-27 Akim Demaille <akim@epita.fr>
5122
5123 * src/output.c (prepare): Drop the muscle `ntbase' which
5124 duplicates ntokens.
5125 * src/bison.simple: Formatting/comment changes.
5126 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
5127 is an undocumented synonym.
5128
5129 2001-12-22 Akim Demaille <akim@epita.fr>
5130
5131 * src/output.c (output_table_data): Change the prototype to use
5132 `int' for array ranges: some invocations do pass an int, not a
5133 short.
5134 Reported by Wayne Green.
5135
5136 2001-12-22 Akim Demaille <akim@epita.fr>
5137
5138 Some actions of web2c.y are improperly triggered.
5139 Reported by Mike Castle.
5140
5141 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
5142 * tests/regression.at (Web2c): Rename as...
5143 (Web2c Report): this.
5144 (Web2c Actions): New.
5145
5146 2001-12-22 Akim Demaille <akim@epita.fr>
5147
5148 Reductions in web2c.y are improperly reported.
5149 Reported by Mike Castle.
5150
5151 * src/conflicts.c (print_reductions): Fix.
5152 * tests/regression.at (Web2c): New.
5153
5154 2001-12-18 Akim Demaille <akim@epita.fr>
5155
5156 Some host fail on `assert (!"foo")', which expands to
5157 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
5158 Reported by Nelson Beebee.
5159
5160 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
5161 `#define it_succeeded 0' and `assert (it_succeeded)'.
5162
5163 2001-12-17 Marc Autret <autret_m@epita.fr>
5164
5165 * src/bison.simple: Don't hard code the skeleton line and filename.
5166 * src/output.c (output_parser): Rename 'line' as 'output_line'.
5167 New line counter 'skeleton_line' (skeleton-line muscle).
5168
5169 2001-12-17 Paul Eggert <eggert@twinsun.com>
5170
5171 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
5172 YYDEBUG must be defined to a nonzero value.
5173
5174 * src/bison.simple (yytname): Do not assume that the user defines
5175 YYDEBUG to a properly parenthesized expression.
5176
5177 2001-12-17 Akim Demaille <akim@epita.fr>
5178
5179 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
5180 nlookaheads is a new member.
5181 Adjust all users.
5182 * src/lalr.h (nlookaheads): Remove this orphan declaration.
5183 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
5184 state.
5185
5186 2001-12-17 Akim Demaille <akim@epita.fr>
5187
5188 * src/files.h, src/files.c (open_files, close_files): Remove.
5189 * src/main.c (main): Don't open/close files, nor invoke lex_free,
5190 let...
5191 * src/reader.c (reader): Do it.
5192
5193 2001-12-17 Akim Demaille <akim@epita.fr>

5200 (flush_reduce): New.
5201 (resolve_sr_conflict): Adjust.
5202
5203 2001-12-17 Akim Demaille <akim@epita.fr>
5204
5205 * src/output.c (output_obstack): Be static and rename as...
5206 (format_obstack): this, to avoid any confusion with files.c's
5207 output_obstack.
5208 * src/reader.h (muscle_obstack): Move to...
5209 * src/output.h: here, since it's defined in output.c.
5210
5211 2001-12-17 Akim Demaille <akim@epita.fr>
5212
5213 * src/output.c (action_row, save_column, default_goto)
5214 (sort_actions, matching_state, pack_vector): Better variable
5215 locality.
5216
5217 2001-12-17 Akim Demaille <akim@epita.fr>
5218
5219 * src/output.c: Various formatting changes.
5220
5221 2001-12-17 Akim Demaille <akim@epita.fr>
5222
5223 * src/files.c (output_files): Free the output_obstack.
5224 * src/main.c (main): Call print and print_graph conditionally.
5225 * src/print.c (print): Work unconditionally.
5226 * src/print_graph.c (print_graph): Work unconditionally.
5227 * src/conflicts.c (log_resolution): Output only if verbose_flag.
5228
5229 2001-12-16 Marc Autret <autret_m@epita.fr>
5230
5231 * src/output.c (actions_output): Fix. When we use %no-lines,
5232 there is one less line per action.
5233
5234 2001-12-16 Marc Autret <autret_m@epita.fr>
5235
5236 * src/bison.simple: Remove a useless #line directive.
5237 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
5238 * src/output.c (get_lines_number): New.
5239 (output_parser): Adjust, now takes care about the lines of a
5240 output muscles.
5241 Fix line numbering.
5242 (actions_output): Computes the number of lines taken by actions.
5243 (output_master_parser): Insert new skeleton which is the name of
5244 the output parser file name.
5245
5246 2001-12-15 Marc Autret <autret_m@epita.fr>
5247
5248 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
5249
5250 2001-12-15 Marc Autret <autret_m@epita.fr>
5251
5252 * src/output.c (output_gram): Keep track of the hairy one.
5253
5254 2001-12-15 Akim Demaille <akim@epita.fr>
5255
5256 Make `make distcheck' work.
5257
5258 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
5259 system.h which uses libgettext.h.
5260
5261 2001-12-15 Akim Demaille <akim@epita.fr>
5262
5263 * src/nullable.c (set_nullable): Useless rules must be skipped,
5264 otherwise, since we range over their symbols, we might look at a
5265 nonterminal which no longer ``exists'', i.e., it is not counted in
5266 `nvars', hence we overflow our arrays.
5267
5268 2001-12-15 Akim Demaille <akim@epita.fr>
5269
5270 The header can also be produced directly, without any obstack!
5271 Yahoo!
5272
5273 * src/files.c, src/files.h (defines_obstack): Remove.
5274 (compute_header_macro): Global.
5275 (defines_obstack_save): Remove.
5276 * src/reader.c (parse_union_decl): No longer output to
5277 defines_obstack: its content can be found in the `stype' muscle
5278 anyway.
5279 (output_token_translations): Merge into...
5280 (symbols_output): this.
5281 Rename as...
5282 (symbols_save): this.
5283 (reader): Adjust.
5284 * src/output.c (header_output): New.
5285 (output): Call it.
5286
5287 2001-12-15 Akim Demaille <akim@epita.fr>
5288
5289 * src/reader.c (parse_union_decl): Instead of handling two obstack
5290 simultaneously, use one to define the `stype' muscle, and use the
5291 value of the latter to fill defines_obstack.
5292 (copy_comment): Remove.
5293 (copy_comment2): Work for a single obstack.
5294 Rename as...
5295 (copy_comment): this.
5296
5297 2001-12-15 Akim Demaille <akim@epita.fr>
5298
5299 * src/lex.c, src/lex.h (xgetc): No longer static.
5300 * src/reader.c (parse_union_decl): Revamp.
5301
5302 2001-12-15 Akim Demaille <akim@epita.fr>
5303
5304 Still making progress in separating Bison into (i) input, (ii)
5305 process, (iii) output: now we can directly output the parser file
5306 without using table_obstack at all.
5307
5308 * src/files.c, src/files.h (table_obstack): Bye bye.
5309 (parser_file_name): New.
5310 * src/files.c (compute_output_file_names): Compute it.
5311 * src/output.c (actions_output, output_parser)
5312 (output_master_parser): To a file instead of an obstack.
5313
5314 2001-12-15 Akim Demaille <akim@epita.fr>
5315
5316 Attach actions to rules, instead of pre-outputting them to
5317 actions_obstack.
5318
5319 * src/gram.h (rule_t): action and action_line are new members.
5320 * src/reader.c (symbol_list): Likewise.
5321 (copy_action): Save the actions within the rule.
5322 (packgram): Save them in rule_table.
5323 * src/output.c (actions_output): New.
5324 (output_parser): Use it on `%%actions'.
5325 (output_rule_data): Don't free rule_table.
5326 (output): Do it.
5327 (prepare): Don't save the `action' muscle.
5328 * src/bison.simple: s/%%action/%%actions/.
5329
5330 2001-12-15 Akim Demaille <akim@epita.fr>
5331
5332 * src/reader.c (copy_action): When --yacc, don't append a `;'
5333 to the user action: let it fail if lacking.
5334 Suggested by Arnold Robbins and Tom Tromey.
5335
5336 2001-12-14 Akim Demaille <akim@epita.fr>
5337
5338 * src/lex.c (literalchar): Simply return the char you decoded, non
5339 longer mess around with obstacks and int pointers.
5340 Adjust all callers.
5341
5342 2001-12-14 Akim Demaille <akim@epita.fr>
5343
5344 * src/lex.c (literalchar): Don't escape the special characters,
5345 just decode them, and keep them as char (before, eol was output as
5346 the 2 char string `\n' etc.).
5347 * src/output.c (output_rule_data): Use quotearg to output the
5348 token strings.
5349
5350 2001-12-13 Paul Eggert <eggert@twinsun.com>
5351
5352 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
5353 Do not infringe on the global user namespace when using C++.
5354 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
5355 All uses of `fprintf' and `stderr' changed.
5356
5357 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
5358
5359 2001-12-13 Akim Demaille <akim@epita.fr>
5360
5361 The computation of nullable is broken: it doesn't handle empty
5362 RHS's properly.
5363
5364 * tests/torture.at (GNU AWK Grammar): New.
5365 * tests/sets.at (Nullable): New.
5366 * src/nullable.c (set_nullable): Instead of blindly looping over
5367 `ritems', loop over the rules, and then over their rhs's.
5368
5369 Work around Autotest bugs.
5370
5371 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
5372 frame, because Autotest understand lines starting with a `+' as
5373 traces from the shell. Then, they are not processed properly.
5374 Admittedly an Autotest bug, but we don't have time to wait for
5375 Autotest to catch up.
5376 * tests/regression.at (Broken Closure): Adjust to the new table
5377 frames.
5378 Move to...
5379 * tests/sets.at: here.
5380
5381 2001-12-13 Akim Demaille <akim@epita.fr>
5382
5383 * src/closure.c (closure): Use nrules instead of playing tricks
5384 with BITS_PER_WORD.
5385
5386 2001-12-13 Akim Demaille <akim@epita.fr>
5387
5388 * src/print.c (print_actions): Output the handling of `$' as the
5389 traces do: shifting the token EOF. Before EOF was treated as a
5390 nonterminal.
5391 * tests/regression.at: Adjust some tests.
5392 * src/print_graph.c (print_core): Complete the set of items via
5393 closure. The next-to-final and final states are still unsatisfying,
5394 but that's to be addressed elsewhere.
5395 No longer output the rule numbers, but do output the state number.
5396 A single loop for the shifts + gotos is enough, but picked a
5397 distinct color for each.
5398 (print_graph): Initialize and finalize closure.
5399
5400 2001-12-13 Akim Demaille <akim@epita.fr>
5401
5402 * src/reader.c (readgram): Remove dead code, an strip useless
5403 braces.
5404 (get_type): Remove, unused.
5405
5406 2001-12-12 Akim Demaille <akim@epita.fr>
5407
5408 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
5409 on that of lib/error.c.
5410
5411 2001-12-12 Akim Demaille <akim@epita.fr>
5412
5413 Some hosts don't like `/' in includes.
5414
5415 * src/system.h: Include libgettext.h without qualifying the path.
5416 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
5417 $(top_srcdir).
5418
5419 2001-12-11 Marc Autret <autret_m@epita.fr>
5420
5421 * src/output.c (output_parser): Remove useless muscle.
5422
5423 2001-12-11 Marc Autret <autret_m@epita.fr>
5424
5425 * src/bison.simple: Remove #line just before %%epilogue. It
5426 is now handled in ...
5427 * src/reader.c (read_additionnal_code): Add the output of a
5428 #line for the epilogue.
5429
5430 2001-12-10 Marc Autret <autret_m@epita.fr>
5431
5432 * src/reader.c (copy_definition): Re-use CPP-outed code which
5433 replace precedent remove.
5434 * src/bison.simple: Remove #line before %%prologue because
5435 %%input-line is wrong at this time.
5436
5437 2001-12-10 Marc Autret <autret_m@epita.fr>
5438
5439 * src/reader.c (symbols_output): Clean up.
5440 * src/output.c (output_gram, output): Clean up.
5441
5442 2001-12-10 Akim Demaille <akim@epita.fr>
5443
5444 * src/lalr.c (initialize_lookaheads): New. Extracted from...
5445 * src/LR0.c (set_state_table): here.
5446 * src/lalr.c (lalr): Call it.
5447
5448 2001-12-10 Akim Demaille <akim@epita.fr>
5449
5450 * src/state.h (shifts): Remove the `number' member: shifts are
5451 attached to state, hence no longer need to be labelled with a
5452 state number.
5453
5454 2001-12-10 Akim Demaille <akim@epita.fr>
5455
5456 Now that states have a complete set of members, the linked list of
5457 shifts is useless: just fill directly the state's shifts member.
5458
5459 * src/state.h (shifts): Remove the `next' member.
5460 * src/LR0.c (first_state, last_state): Remove.
5461 Adjust the callers.
5462 (augment_automaton): Don't look for the shifts that must be added
5463 a shift on EOF: it is those of the state we looked for! But now,
5464 since shifts are attached, it is no longer needed to looking
5465 merely by its id: its number.
5466
5467 2001-12-10 Akim Demaille <akim@epita.fr>
5468
5469 * src/LR0.c (augment_automaton): Better variable locality.
5470 Remove an impossible branch: if there is a state corresponding to
5471 the start symbol being shifted, then there is shift for the start
5472 symbol from the initial state.
5473
5474 2001-12-10 Akim Demaille <akim@epita.fr>
5475
5476 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
5477 only when appropriate: when insert_start_shifting_state' is not
5478 invoked.
5479 * tests/regression.at (Rule Line Numbers): Adjust.
5480
5481 2001-12-10 Akim Demaille <akim@epita.fr>
5482
5483 * src/LR0.c (augment_automaton): Now that all states have shifts,
5484 merge the two cases addition shifts to the initial state.
5485
5486 2001-12-10 Akim Demaille <akim@epita.fr>
5487
5488 * src/lalr.c (set_state_table): Move to...
5489 * src/LR0.c: here.
5490 * src/lalr.c (lalr): Don't call it...
5491 * src/LR0.c (generate_states): do it.
5492 * src/LR0.h (first_state): Remove, only the table is used.
5493
5494 2001-12-10 Akim Demaille <akim@epita.fr>
5495
5496 * src/LR0.h (first_shift, first_reduction): Remove.
5497 * src/lalr.c: Don't use first_shift: find shifts through the
5498 states.
5499
5500 2001-12-10 Akim Demaille <akim@epita.fr>
5501
5502 * src/LR0.c: Attach shifts to states as soon as they are
5503 computed.
5504 * src/lalr.c (set_state_table): Instead of assigning shifts to
5505 state, just assert that the mapping was properly done.
5506
5507 2001-12-10 Akim Demaille <akim@epita.fr>
5508
5509 * src/LR0.c (insert_start_shift): Rename as...
5510 (insert_start_shifting_state): this.
5511 (insert_eof_shifting_state, insert_accepting_state): New.
5512 (augment_automaton): Adjust.
5513 Better locality of the variables.
5514 When looking if the start_symbol is shifted from the initial
5515 state, using `while (... symbol != start_symbol ...)' sounds
5516 better than `while (... symbol < start_symbol ...)': If fail
5517 to see how the order between symbols could be relevant!
5518
5519 2001-12-10 Akim Demaille <akim@epita.fr>
5520
5521 * src/getargs.h: Don't declare `spec_name_prefix' and
5522 `spec_file_prefix', declared by src/files.h.
5523 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
5524 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
5525 * src/output.c (prepare): Adjust.
5526 * src/reader.c (symbols_output): Likewise.
5527 * src/vmsgetargs.c: Vaguely adjust, but who cares?
5528
5529 2001-12-10 Akim Demaille <akim@epita.fr>
5530
5531 * src/muscle_tab.c (muscle_init): NULL is a better default than
5532 `"0"'.
5533
5534 2001-12-10 Akim Demaille <akim@epita.fr>
5535
5536 * src/reader.c (reader): Calling symbols_output once is enough.
5537
5538 2001-12-10 Akim Demaille <akim@epita.fr>
5539
5540 Now that states have a complete set of members, the linked list of
5541 reductions is useless: just fill directly the state's reductions
5542 member.
5543
5544 * src/state.h (struct reductions): Remove member `number' and
5545 `next'.
5546 * src/LR0.c (first_reduction, last_reduction): Remove.
5547 (save_reductions): Don't link the new reductions, store them in
5548 this_state.
5549 * src/lalr.c (set_state_table): No need to attach reductions to
5550 states, it's already done.
5551 * src/output.c (output_actions): No longer free the shifts, then
5552 the reductions, then the states: free all the states and their
5553 members.
5554
5555 2001-12-10 Akim Demaille <akim@epita.fr>
5556
5557 * src/options.c (OPTN, DRTV, BOTH): New.
5558 (option_table): Use them.
5559
5560 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
5561 the job of system.h.
5562 * src/options.c: Don't include stdio.h and xalloc.h for the same
5563 reasons.
5564
5565 2001-12-10 Akim Demaille <akim@epita.fr>
5566
5567 * src/output.c (output, prepare): Make sure the values of the
5568 muscles `action' and `prologue' are 0-terminated.
5569
5570 2001-12-10 Akim Demaille <akim@epita.fr>
5571
5572 Clean up GCC warnings.
5573
5574 * src/reader.c (copy_action): `buf' is not used.
5575 (parse_skel_decl): Be static.
5576 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
5577 * src/options.h (create_long_option_table): Have a real prototype.
5578 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
5579 (hash_delete_at): Return const void *.
5580 Adjust casts to preserve the const.
5581
5582 2001-12-10 Akim Demaille <akim@epita.fr>
5583
5584 * configure.in: Require 2.52g.
5585 M4 is not needed, but AUTOM4TE is.
5586 * m4/m4.m4: Remove.
5587 * tests/Makefile.am: Adjust.
5588
5589 2001-12-10 Akim Demaille <akim@epita.fr>
5590
5591 One structure for states is enough, even though theoretically
5592 there are LR(0) states and LALR(1) states.
5593
5594 * src/lalr.h (state_t): Remove.
5595 (state_table): Be state_t **, not state_t *.
5596 * src/state.h (core, CORE_ALLOC): Rename as...
5597 (state_t, STATE_ALLOC): this.
5598 Add the LALR(1) members: shifts, reductions, errs.
5599 * src/LR0.c (state_table): Rename as...
5600 (state_hash): this, to avoid name clashes with the global
5601 `state_table'.
5602 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
5603 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
5604
5605 2001-12-10 Akim Demaille <akim@epita.fr>
5606
5607 Bison dumps core on bash.y.
5608 Reported by Pascal Bart.
5609
5610 * src/warshall.c (bitmatrix_print): New.
5611 (TC): Use it.
5612 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
5613 j must be the outer loop.
5614 * tests/regression.at (Broken Closure): New.
5615
5616 2001-12-05 Akim Demaille <akim@epita.fr>
5617
5618 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
5619 its argument.
5620 Reported by Peter Hámorský.
5621
5622 2001-12-05 Akim Demaille <akim@epita.fr>
5623
5624 * src/conflicts.c (err_table): Remove.
5625 (resolve_sr_conflict): Adjust.
5626 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
5627 Rename as...
5628 (state_t.reductions, state_t.shifts): this.
5629
5630 2001-12-05 Akim Demaille <akim@epita.fr>
5631
5632 * src/reduce.c (reduce_grammar_tables): No longer disable the
5633 removal of useless rules via CPP but via `if (0)', so that the
5634 compiler still check the code is valid.
5635 For instance, it should have noticed `rline' no longer exists: use
5636 the `line' member of rule_t.
5637 * src/gram.c (dummy, rline): Remove, unused.
5638
5639 2001-12-05 Akim Demaille <akim@epita.fr>
5640
5641 * src/output.c (pack_vector): Use assert, not berror.
5642 * src/main.c (berror): Remove, unused.
5643
5644 2001-12-05 Akim Demaille <akim@epita.fr>
5645
5646 New experimental feature: if --verbose --trace output all the
5647 items of a state, not only its kernel.
5648
5649 * src/print.c (print_core): If `trace_flag', then invoke closure
5650 before outputting the items of the state (print_core is no longer
5651 a correct name them).
5652 (print_results): Invoke new_closure/free_closure if needed.
5653
5654 2001-12-05 Akim Demaille <akim@epita.fr>
5655
5656 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
5657 * src/closure.c, src/closure.h (itemsetsize): Rename as...
5658 (nitemset): for consistency with the rest of the project.
5659
5660 2001-12-05 Akim Demaille <akim@epita.fr>
5661
5662 * src/closure.c (print_closure): Improve.
5663 (closure): Use it for printing input and output.
5664
5665 2001-12-05 Akim Demaille <akim@epita.fr>
5666
5667 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5668 indexed by nonterminals.
5669
5670 2001-12-05 Akim Demaille <akim@epita.fr>
5671
5672 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
5673 what it was!).
5674 * src/warshall.h: Remove accidental duplication of the content.
5675
5676 2001-12-05 Akim Demaille <akim@epita.fr>
5677
5678 * src/closure.c (set_fderives): De-obfuscate.
5679

5689
5690 * src/output.c (action_row): De-obfuscate
5691 using the good o' techniques: arrays not pointers, variable
5692 locality, BITISSET, RESETBIT etc.
5693
5694 2001-12-05 Akim Demaille <akim@epita.fr>
5695
5696 Pessimize the code to simplify it: from now on, all the states
5697 have a valid SHIFTS, which NSHIFTS is possibly 0.
5698
5699 * src/LR0.c (shifts_new): Be global and move to..
5700 * src/state.c, src/state.h: here.

5703
5704 2001-12-05 Akim Demaille <akim@epita.fr>
5705
5706 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
5707 * src/conflicts.c: Use it.
5708 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
5709 incorrectly ``simplified''.
5710
5711 2001-12-05 Akim Demaille <akim@epita.fr>
5712
5713 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

5723
5724 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
5725 (print_reductions): De-obfuscate using the good o' techniques:
5726 arrays not pointers, variable locality, BITISSET.
5727
5728 2001-12-05 Akim Demaille <akim@epita.fr>
5729

5760
5761 * src/lalr.c (matrix_print): New.
5762 (transpose): Use it.
5763 Use arrays instead of pointers.
5764
5765 2001-12-05 Akim Demaille <akim@epita.fr>
5766
5767 * src/lalr.c (maxrhs): Move to...
5768 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5769 * src/lalr.c (build_relations): Adjust.
5770
5771 2001-12-05 Akim Demaille <akim@epita.fr>
5772
5773 * src/lalr.c (transpose): Free the memory allocated to the
5774 argument, as it is replaced by the results by the unique caller.
5775 (build_relations): Merely invoke transpose: it handles the memory
5776 deallocation.
5777 Improve variable locality.
5778 Avoid variables used as mere abbreviations.
5779 (compute_lookaheads): Use arrays instead of pointers.
5780

5795 * src/lalr.c (traverse): Use arrays instead of pointers.
5796
5797 2001-12-05 Akim Demaille <akim@epita.fr>
5798
5799 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5800 the handling of squeue.
5801 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5802
5803 2001-12-05 Akim Demaille <akim@epita.fr>
5804
5805 Because useless nonterminals are now kept alive (instead of being
5806 `destroyed'), we now sometimes examine them, and store information
5807 related to them. Hence we need to know their number, and adjust
5808 memory allocations.
5809
5810 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5811 static.
5812 * src/LR0.c (allocate_itemsets): The memory allocated to
5813 `symbol_count' was used for two different purpose: once to count
5814 the number of occurrences of each symbol, and later reassigned to
5815 `shift_symbol', containing the symbol that can be shifted from a
5816 given state.
5817 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5818 only, and...
5819 (new_itemsets): Allocate `shift_symbol' here.
5820 (allocate_itemsets): symbol_count includes useless nonterminals.
5821 Make room for them.
5822 (free_storage): Use `free', not `XFREE', for pointers that cannot
5823 be null.
5824
5825 2001-12-05 Akim Demaille <akim@epita.fr>
5826
5827 * src/nullable.c (set_nullable): Deobfuscate the handling of
5828 ritem.
5829 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5830
5831 2001-12-05 Akim Demaille <akim@epita.fr>
5832
5833 * src/gram.c, src/gram.h (ritem_print): New.
5834 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5835 (This useless function was defined only to work around VMS linkers
5836 that can't handle compilation units with variables only).
5837 * src/reduce.c (dump_grammar): Use it to trace the construction of
5838 ritem.
5839
5840 2001-12-04 Paul Eggert <eggert@twinsun.com>
5841
5842 * src/bison.simple (union yyalloc): Change member names
5843 to be the same as the stack names.
5844 (yyparse): yyptr is now union yyalloc *, not char *.
5845 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5846 and may generate better code on some machines.
5847 (yystpcpy): Use prototype if __STDC__ is defined, not just
5848 if __cplusplus is defined.
5849
5850 2001-11-30 Akim Demaille <akim@epita.fr>
5851
5852 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
5853 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
5854 Gettext doesn't compile cleanly, and dies with -Werror.
5855 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
5856 Include WARNING_CFLAGS here.
5857 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
5858 before being defined.
5859
5860 2001-11-27 Paul Eggert <eggert@twinsun.com>
5861
5862 * lib/quotearg.h (quotearg_n, quotearg_n_style):
5863 First arg is int, not unsigned.
5864 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
5865 (SIZE_MAX, UINT_MAX): New macros.
5866 (quotearg_n_options): Abort if N is negative.
5867 Avoid overflow check on hosts where size_t is 64 bits and int
5868 is 32 bits, as overflow is impossible there.
5869 Fix off-by-one typo that caused unnecessary reallocation.
5870
5871 2001-11-29 Paul Eggert <eggert@twinsun.com>
5872

5874
5875 * doc/bison.texinfo (Bison Parser): Discuss system headers
5876 and their effect on the user name space.

5878 * src/bison.simple:
5879 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
5880 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
5881 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
5882
5883 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
5884 on user names when possible.
5885
5886 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5887 Simplify test for whather <alloca.h> exists.
5888
5889 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
5890
5891 (<stdio.h>): Include if YYDEBUG.
5892
5893 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5894 ! defined (yyoverflow) && ! defined (yymemcpy).
5895
5896 (yymemcpy, yyparse): Rename local variables as needed so that
5897 they all begin with 'yy'.
5898
5899 (yystrlen, yystpcpy): New functions.
5900
5901 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5902 All uses changed.
5903
5904 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5905 instead of relying on string.h functions. Use YYSTACK_ALLOC
5906 and YYSTACK_FREE instead of malloc and free.
5907
5908 2001-11-30 Akim Demaille <akim@epita.fr>

5917
5918 2001-11-30 Akim Demaille <akim@epita.fr>
5919
5920 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5921 if body instead of `;' to pacify GCC's warnings.
5922
5923 2001-11-30 Akim Demaille <akim@epita.fr>
5924
5925 Instead of mapping the LHS of unused rules to -1, keep the LHS
5926 valid, but flag the rules as invalid.
5927
5928 * src/gram.h (rule_t): `useful' is a new member.
5929 * src/print.c (print_grammar): Adjust.
5930 * src/derives.c (set_derives): Likewise.
5931 * src/reader.c (packgram, reduce_output): Likewise.

5942 2001-11-30 Akim Demaille <akim@epita.fr>
5943
5944 * src/reduce.c (nonterminals_reduce): Instead of throwing away
5945 useless nonterminals, move them at the end of the symbol arrays.
5946 (reduce_output): Adjust.
5947 * tests/reduce.at (Useless Nonterminals): Adjust.
5948
5949 2001-11-30 Akim Demaille <akim@epita.fr>

5956 2001-11-29 Paul Eggert <eggert@twinsun.com>
5957
5958 * src/bison.simple (YYSTACK_REALLOC): Remove.
5959 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
5960 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5961 New macros.
5962 (union yyalloc): New type.
5963 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5964 an arbitrary restriction on hosts where size_t is wider than int.
5965
5966 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5967 a parser stack overflow. Allocate just one block of memory for all
5968 three stacks, instead of allocating three blocks; this typically is
5969 faster and reduces fragmentation.
5970
5971 Do not limit the number of items in the stack to a value that fits
5972 in 'int', as this is an arbitrary limit on hosts with 64-bit
5973 size_t and 32-bit int.
5974
5975 2001-11-29 Marc Autret <autret_m@epita.fr>

6022
6023 2001-11-28 Akim Demaille <akim@epita.fr>
6024
6025 * src/closure.c (closure): `b' and `ruleno' denote the same value:

6034
6035 * src/closure.c (closure): No longer optimize the special case

6039 2001-11-28 Akim Demaille <akim@epita.fr>
6040
6041 * src/closure.c (closure): `r' and `c' are new variables, used to

6400 * tests/calc.at, tests/output.at, tests/regression.at,
6401 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
6402 now the tests are run in private dirs, therefore AC_CLEANUP and

6405 use abs. path to find config.h.
6406 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

6429 * src/lex.c (parse_percent_token): Replace equal_offset with

7808
7809 * src/lex.h: Rename all the tokens:

7831 * src/reader.c (read_declarations): Adjust.
7832 * src/files.c (open_files): Don't call `compute_base_names', don't
7833 compute `attrsfile' since they depend upon data which might be
7834 *in* the input file now.
7835 (output_files): Do it here.
7836 * src/output.c (output_headers): Document the fact that this patch
7837 introduces a guaranteed SEGV for semantic parsers.
7838 * doc/bison.texinfo: Document them.

7972
7973 * lib/obstack.h: Formatting changes.
7974 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
7975 prevents type checking.
7976 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
7977 cast the value to (void *): assigning a `foo *' to a `void *'
7978 variable is valid.
7979 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
7980 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
7981 append characters.

8023 * src/output.c (output): Remove useless variables.
8024 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
8025 argument `data' for consistency with the prototypes.
8026 Qualify it `const'.
8027 (obstack_copy, obstack_copy0): Rename the second argument as
8028 `address' for consistency. Qualify it `const'.
8029 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
8030 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
8031 `const' their input argument (`data' or `address').

8055
8056 * src/files.c (obstack_save): New function.
8057 (done): Rename as...
8058 (output_files): this.
8059 Use `obstack_save'.
8060 * src/main.c (main): Don't use `atexit' to register `done', since
8061 it no longer has to remove tmp files, just call `output_files'
8062 when there are no errors.
8063
8064 2000-11-02 Akim Demaille <akim@epita.fr>
8065

8085
8086 Change each use of `fattrs' into a use of `attrs_obstack'.

8128 (lex): Use it.
8129 * src/reader.c (copy_dollar): Likewise.
8130
8131 2000-10-16 Akim Demaille <akim@epita.fr>
8132
8133 * src/reader.c (copy_comment2): Expect the input stream to be on
8134 the `/' which is suspected to open a comment, instead of being
8135 called after `//' or `/*' was read.
8136 (copy_comment, copy_definition, parse_union_decl, copy_action)
8137 (copy_guard): Adjust.
8138
8139 2000-10-16 Akim Demaille <akim@epita.fr>
8140
8141 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

8162
8163 * doc/bison.texinfo: Various typos spotted by Neil Booth.
8164
8165 2000-10-04 Akim Demaille <akim@epita.fr>
8166
8167 When a literal string is used to define two different tokens,
8168 `bison -v' segfaults.
8169 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
8170
8171 * tests/regression.m4: New file.
8172 Include the core of the sample provided by Piotr Gackiewicz.

8174 properly.
8175
8176 2000-10-04 Akim Demaille <akim@epita.fr>
8177
8178 * src/reader.c (parse_expect_decl): Keep `count' within the size
8179 of `buffer'.
8180 From Neil Booth.
8181
8182 2000-10-02 Paul Eggert <eggert@twinsun.com>
8183
8184 * bison.s1 (yyparse): Assign the default value
8185 unconditionally, to avoid a GCC warning and make the parser a
8186 tad smaller.
8187
8188 2000-10-02 Akim Demaille <akim@epita.fr>
8189
8190 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
8191 options.
8192
8193 2000-10-02 Akim Demaille <akim@epita.fr>
8194
8195 * src/derives.c, src/print.c, src/reduce.c: To ease the
8196 translation, move some `\n' out of the translated strings.
8197
8198 2000-10-02 Akim Demaille <akim@epita.fr>
8199
8200 The location tracking mechanism is precious for parse error
8201 messages. Nevertheless, it is enabled only when `@n' is used in
8202 the grammar, which is a different issue (you can use it in error
8203 message, but not in the grammar per se). Therefore, there should
8204 be another means to enable it.
8205
8206 * src/getargs.c (getargs): Support `--locations'.
8207 (usage): Report it.
8208 * src/getargs.h (locationsflag): Export it.
8209 * src/lex.c (percent_table): Support `%locations'.
8210 * src/reader.c (yylsp_needed): Remove this variable, now replaced
8211 with `locationsflag'.
8212 * doc/bison.texinfo: Document `--locations' and `%locations'.
8213 Sort the options.
8214 * tests/calc.m4: Test it.
8215
8216 For regularity of the names, replace each
8217 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
8218 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
8219 In addition replace each `flag' with `_flag'.
8220
8221 2000-10-02 Akim Demaille <akim@epita.fr>
8222
8223 Also test parse error messages, including with YYERROR_VERBOSE.
8224
8225 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
8226 associative).
8227 Use it to check the computations.
8228 Use it to check `nonassoc' is honored.
8229 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
8230 `--yyerror-verbose'.
8231 (_AT_CHECK_CALC): Adjust to this option.
8232 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
8233
8234 2000-10-02 Akim Demaille <akim@epita.fr>
8235
8236 Test also `--verbose', `--defines' and `--name-prefix'. Testing
8237 the latter demonstrates a flaw in the handling of non debugging
8238 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
8239 was used in order to simplify:
8240
8241 #if YYDEBUG
8242 if (yydebug)
8243 {
8244 ...
8245 }
8246 #endif
8247
8248 into
8249
8250 if (yydebug)
8251 {
8252 ...
8253 }
8254
8255 unfortunately this leads to a CPP conflict when
8256 `--name-prefix=foo' is used since it produces `#define yydebug
8257 foodebug'.
8258
8259 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
8260 (YYDPRINTF): New macro.
8261 Spread its use.
8262 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
8263 the bison options.
8264 Also test `--verbose', `--defines' and `--name-prefix'.
8265
8266 2000-10-02 Akim Demaille <akim@epita.fr>
8267
8268 Improve the readability of the produced parsers.
8269
8270 * src/bison.s1: Formatting changes.
8271 Improve the comment related to the `$' mark.
8272 (yydefault): Don't fall through to `yyresume': `goto' there.
8273 * src/output.c (output_parser): When the `$' is met, skip the end
8274 of its line.
8275 New variable, `number_of_dollar_signs', to check there's exactly
8276 one `$' in the parser skeleton.
8277
8278 2000-10-02 Akim Demaille <akim@epita.fr>
8279
8280 * lib/xstrdup.c: New file, from the fileutils.
8281 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
8282 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
8283 instead of strlen + xmalloc + strcpy.
8284 * src/symtab.c (copys): Remove, use xstrdup instead.
8285
8286 2000-10-02 Akim Demaille <akim@epita.fr>
8287
8288 * src/gram.h (associativity): New enum type which replaces the
8289 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
8290 `right_assoc', `left_assoc' and `non_assoc'.
8291 Adjust all dependencies.
8292 * src/reader.c: Formatting changes.
8293 (LTYPESTR): Don't define it, use it as a literal in
8294 `reader_output_yylsp'.
8295 * src/symtab.h (symbol_class): New enum type which replaces the
8296 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
8297 `sunknown', `stoken and `snterm'.
8298
8299 2000-10-02 Akim Demaille <akim@epita.fr>
8300
8301 * src/getargs.c (fixed_outfiles): Rename as...
8302 (yaccflag): for consistency and accuracy.
8303 Adjust dependencies.
8304
8305 2000-10-02 Akim Demaille <akim@epita.fr>
8306
8307 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
8308 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
8309 difficult and introduced a lot of core dump. It turns out that
8310 Bison used an implementation of `xmalloc' based on `calloc', and
8311 at various places it does depend upon the initialization to 0. I
8312 have not tried to isolate the pertinent places, and all the former
8313 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
8314 someone should address this issue.
8315
8316 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
8317 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
8318 files.
8319 Adjust dependencies.

8324
8325 Various anti-`extern in *.c' changes.
8326
8327 * src/system.h: Include `assert.h'.
8328
8329 2000-10-02 Akim Demaille <akim@epita.fr>
8330
8331 * src/state.h (nstates, final_state, first_state, first_shift)
8332 (first_reduction): Move their exportation from here...
8333 * src/LR0.h: to here.
8334 Adjust dependencies.
8335 * src/getargs.c (statisticsflag): New variable.
8336 Add support for `--statistics'.
8337 Adjust dependencies.
8338
8339 Remove a lot of now useless `extern' statements in most files.
8340
8341 2000-10-02 Akim Demaille <akim@epita.fr>
8342
8343 * src/LR0.h: New file.

8353 Adjust dependencies.
8354
8355 2000-10-02 Akim Demaille <akim@epita.fr>
8356
8357 * src/conflicts.c (conflict_report): New function.
8358 (conflict_log, verbose_conflict_log): Replace with...
8359 (print_conflicts): this function.
8360 Adjust dependencies.
8361 * src/conflicts.h: New file.
8362 Propagate its inclusion.
8363
8364 2000-10-02 Akim Demaille <akim@epita.fr>
8365
8366 * src/nullable.h: New file.
8367 Propagate its inclusion.

8377
8378 2000-10-02 Akim Demaille <akim@epita.fr>
8379
8380 * src/files.c: Formatting changes.

8394
8395 2000-10-02 Akim Demaille <akim@epita.fr>
8396
8397 * src/lex.h: Prototype `lex.c' exported functions.
8398 * src/reader.c: Adjust.
8399 * src/lex.c: Formatting changes.
8400 (safegetc): Rename as...
8401 (xgetc): this.
8402
8403 2000-10-02 Akim Demaille <akim@epita.fr>
8404
8405 * src/lalr.h: New file.
8406 Propagate its inclusion instead of prototypes and `extern'.
8407 * src/lalr.c: Formatting changes, topological sorting etc.
8408
8409 2000-10-02 Akim Demaille <akim@epita.fr>
8410
8411 * src/output.c (token_actions): Introduce a temporary array,
8412 YYDEFACT, that makes it possible for this function to use
8413 output_short_table.
8414
8415 2000-10-02 Akim Demaille <akim@epita.fr>
8416
8417 `user_toknums' is output as a `short[]' in `output.c', while it is
8418 defined as a `int[]' in `reader.c'. For consistency with the
8419 other output tables, `user_toknums' is now defined as a table of
8420 shorts.
8421
8422 * src/reader.c (user_toknums): Be a short table instead of an int
8423 table.
8424 Adjust dependencies.
8425
8426 Factor the short table outputs.
8427
8428 * src/output.c (output_short_table): New function.
8429 * src/output.c (output_gram, output_stos, output_rule_data)
8430 (output_base, output_table, output_check): Use it.
8431
8432 2000-10-02 Akim Demaille <akim@epita.fr>
8433
8434 * src/output.c (output): Topological sort of the functions, in
8435 order to get rid of the `static' prototypes.
8436 No longer use `register'.
8437 * src/output.h: New file.
8438 Propagate its inclusion in files explicitly prototyping functions
8439 from output.c.
8440
8441 2000-09-21 Akim Demaille <akim@epita.fr>
8442

8683
8684 Change the handling of @s so that they behave exactly like $s.
8685 There is now a pseudo variable @$ (readble and writable), location
8686 of the lhs of the rule (by default ranging from the location of
8687 the first symbol of the rhs, to the location of the last symbol,
8688 or, if the rhs is empty, YYLLOC).

8723 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

8728

8765 * m4/Makefile.am (EXTRA_DIST): New variable.
8766 * m4/gettext.m4: New file, from the fileutils.

9415 (read_declarations): Improve the error message for
9416 an invalid character. Do not abort.
9417 (read_declarations, copy_guard, copy_action): Use
9418 printable_version to avoid unprintable characters in printed output.
9419 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
9420 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
9421 Allow the type of a non-terminal can be given
9422 more than once, as long as all specifications give the same type.
9423
9424 * src/output.c:
9425 (output_headers, output_trailers, output, output_gram)
9426 (output_rule_data): Implement noparserflag variable.
9427 Implement toknumflag variable.
9428 (output): Call reader_output_yylsp to output LTYPESTR.
9429
9430 * src/main.c (main):
9431 If reader sees an error, don't process the grammar.
9432 (fatals): Updated to not use VARARGS1.
9433 (printable_version, int_to_string, warn, warni, warns, warnss)
9434 (warnsss): New error reporting functions. Avoid abort for error.
9435
9436 * src/lex.h:
9437 Added THONG and NOOP for alias processing.

9446 (literalchar, lex, parse_percent_token): Made tokenbuffer
9447 always contain the token. This includes growing the token
9448 buffer while reading an integer.
9449 (parse_percent_token): Replaced if-else statement with percent_table.
9450 (parse_percent_token): Added % declarations as another
9451 way to specify the flags -n, -l, and -r. Also added hooks for
9452 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
9453 major changes to files.c.
9454 (lex) Retain in the incoming stream a character following
9455 an incorrect '/'.
