[bison.git] / ChangeLog
1 2010-08-04 Joel E. Denny <joeldenny@joeldenny.org>
2
3 doc: fix -W and %expect documentation some.
4 * NEWS (2.4.3): Mention that there are documentation fixes.
5 * doc/bison.texinfo (Expect Decl): Make it clear that %expect
6 turns conflicts into errors not warnings.
7 (Shift/Reduce): Likewise.
8 (Bison Options): Don't mention -Wsyntax. It doesn't exist.
9
10 2010-08-01 Joel E. Denny <joeldenny@joeldenny.org>
11
12 -Werror: fix for rules useless in parser after conflicts.
13 * NEWS (2.4.3): Document fix.
14 * src/complain.c (error_message): Extend to handle incomplete
15 error messages so warn and warn_at can be used in more cases.
16 * src/gram.c (grammar_rules_useless_report): Use warn_at so that
17 -Werror is always obeyed.
18 * src/reduce.c (reduce_print): Use warn so that the "warnings
19 being treated as errors" message is printed consistently before
20 the first warning message. This makes testing easier.
21 * tests/local.at (AT_BISON_WERROR_MSG): New macro.
22 (AT_BISON_CHECK_NO_XML): Extend to check -Werror and
23 --warnings=error when warnings appear in bison's stderr.

197
198 doc: please Emacs.
199 * doc/bison.texinfo (Local Variables): Move this after the
200 LocalWords, since the latter are looked for in the whole document,
201 while the former are looked for only at its end.
202 Require american spell checking.
203
204 2010-05-10 Akim Demaille <demaille@gostai.com>
205
206 doc: fix lalr1.cc documentation.

212
213 2010-05-10 Akim Demaille <demaille@gostai.com>
214
215 c++: use YYRHSLOC.
216 * data/lalr1.cc (YYRHSLOC): New.
217 (YYLLOC_DEFAULT): Use it.
218 * data/glr.cc: If location_type was user defined, do not include
219 location.hh, and do not produce location.hh and position.hh.
220 * tests/calc.at (YYLLOC_DEFAULT): Use YYRHSLOC.
221 Check that glr.cc supports user defined location_type.
222 * NEWS: Document this.
223
224 2010-05-07 Akim Demaille <demaille@gostai.com>

232 * tests/synclines.at (AT_SYNCLINES_COMPILE): More distcc patterns.
233 (AT_TEST_SYNCLINE): Remove GCC 4.5 protection which is already
234 taken care of in AT_SYNCLINES_COMPILE.
235
236 2010-05-04 Akim Demaille <demaille@gostai.com>
237
238 lalr1.cc: don't generate location.hh when location_type is defined
239 * data/bison.m4 (b4_percent_define_get): Accept a default value.
240 * data/c++.m4: Do not provide a default value for the %define
241 variable location_type, rather, use b4_percent_define_get with a
242 default argument where its value is needed.
243 * data/lalr1.cc: Do not load location.cc (which outputs both
244 location.hh and position.hh) if the user defined location_type.
245 Do not include location.hh either.
246
247 2010-05-04 Akim Demaille <demaille@gostai.com>
248
249 lalr1.cc: minor refactoring.
250 * data/lalr1.cc: Don't issue empty namespaces.
251
252 2010-05-04 Akim Demaille <demaille@gostai.com>
253
254 tests: fix %printer.
255 Currently, there is no check that %printer ... <foo> (nor
256 %destructor) is about an existing <foo> type. This C++ test had
257 it wrong (<::std::string> vs. <std::string>).

271 location_type changes.
272
273 2010-05-01 Joel E. Denny <joeldenny@joeldenny.org>
274
275 tests: fix maintainer-xml-check.
276 * data/xslt/xml2dot.xsl (xsl:template match="bison-xml-report"):
277 Update output to include comments now produced by --graph.
278 (xsl:template match="automaton"): As for --graph, name the
279 digraph after the grammar file.
280 * src/print-xml.c (escape_bufs): Enlarge array.
281 (print_xml): Add bug-report and url attributes to
282 bison-xml-report element.
283
284 2010-05-01 Joel E. Denny <joeldenny@joeldenny.org>
285
286 In DOT output, convert from "/*" comments to "//" comments.
287 This handles the possibility that a "*/" might appear in
288 variable portions of those comments at some point in the future.
289 * src/graphviz.c (start_graph): Implement.
290
291 2010-04-30 Joel E. Denny <joeldenny@joeldenny.org>

295 (2.4.2): Here.
296
297 2010-04-30 Joel E. Denny <joeldenny@joeldenny.org>
298
299 Revert 2009-12-30 change for undefined %prec token complaints.
300 That is, keep them as warnings because that should be sufficient
301 to satisfy POSIX without creating backward compatibility issues.
302 Suggested by Richard Stallman at
303 <http://lists.gnu.org/archive/html/bison-patches/2010-03/msg00033.html>.
304 * NEWS (2.5): Remove mention of complaint.
305 * src/reader.c (grammar_rule_check): Convert complaint back to
306 warning.
307 * tests/input.at (%prec's token must be defined): Update.
308
309 2010-04-25 Joel E. Denny <joeldenny@joeldenny.org>
310
311 build: don't require src/bison during bootstrap.
312 Suggested by Eric Blake at
313 <http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00003.html>.

315 src/parse-gram.[ch] are stamped later than src/parse-gram.y.
316
317 2010-04-25 Joel E. Denny <joeldenny@joeldenny.org>

334 define the appropriate AT_LOC accessors.
335 * tests/calc.at: Use AT_LOC accessors.
336
337 2010-04-13 Akim Demaille <demaille@gostai.com>
338
339 test location_type.

346
347 2010-04-13 Akim Demaille <demaille@gostai.com>
348

351
352 2010-04-13 Akim Demaille <demaille@gostai.com>
353
354 tests: don't depend on the actual location type.
355 * tests/calc.at: Use yy::parser::location_type rather than
356 yy::location, since the former is always right, and might point to
357 another type than the latter.
358
359 2010-04-13 Akim Demaille <demaille@gostai.com>
360
361 formatting changes.

393 lalr1.java.
394 * data/lalr1.cc (yy::parser::parse): Increase size of
395 yyerror_range and adjust subscripting so you don't have to

459 * NEWS (2.4.2): Set version and date. For the recent test suite
460 portability fixes, don't be so optimistic about their success
461 given the lack of feedback on the affected platforms.

463 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
464
465 tests: fix maintainer-xml-check for recent changes.
466 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use
467 AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an
468 output file whose name conflicts with a previous output file
469 is now never generated.
470
471 2010-02-22 Joel E. Denny <jdenny@ces.clemson.edu>
472
473 portability: fix several issues with M4 subprocess.
474
475 M4's output pipe was not being drained upon fatal errors during
476 scan_skel. As a result, broken-pipe messages from M4 were seen
477 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
478 failure in the test suite. The problem was that, on platforms
479 where the default disposition for SIGPIPE is ignore instead of
480 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
481 then reported it. However, there's some sort of race condition,
482 because the new test group occasionally succeeded.
483 Reported by Albert Chin at
484 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
485
486 There were also problems with the test suite livelocking on
487 Tru64 5.1b. Reported by Didier Godefroy at
488 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
489 Switching to create_pipe_bidi suggested by Akim Demaille.
490
491 To attempt to solve both of these problems, switch to gnulib's
492 create_pipe_bidi and register M4 process as a slave. Along the
493 way, clean up file name conflict handling, which was affected by
494 the broken-pipe problem before the switch.
495 * NEWS (2.4.2): Document.
496 * THANKS (Didier Godefroy): Add.
497 * bootstrap.conf (gnulib_modules): Add pipe.
498 * gnulib: Update to latest to make sure we have all the latest
499 fixes.
500 * lib/local.mk (lib_libbison_a_SOURCES): Remove subpipe.h and
501 subpipe.c.
502 * po/POTFILES.in (lib/subpipe.c): Remove.
503 * src/files.c (compute_output_file_names): Update invocations
504 of output_file_name_check.
505 (output_file_name_check): In the case that the grammar file
506 would be overwritten, use complain instead of fatal, but replace
507 the output file name with /dev/null. Use the /dev/null solution
508 for the case of two conflicting output files as well because it
509 seems safer in case Bison one day tries to open both files at
510 the same time.
511 * src/files.h (output_file_name_check): Update prototype.
512 * src/output.c (output_skeleton): Use create_pipe_bidi and
513 wait_subprocess. Assert that scan_skel completely drains the
514 pipe.
515 * src/scan-skel.l (at_directive_perform): Update
516 output_file_name_check invocation.
517 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the
518 grammar file actually isn't overwritten.
519 (Conflicting output files: -o foo.y): Update expected output.
520 * tests/skeletons.at (Fatal errors but M4 continues producing
521 output): New test group.

587
588 Stop equating LR(0) with nondeterminism and LALR(1) with
589 determinism. That is, if all states are consistent, then LR(0)
590 tables are deterministic. On the other hand, LALR(1) tables
591 might be nondeterministic before conflict resolution, and GLR
592 permits LALR(1) tables to remain nondeterministic.

632 portability: `<' and `>' are not always defined on addresses.
633 Specifically, don't sort objects by their memory addresses when
634 they're not allocated in the same array or other object. Though
635 I haven't found a test case where that fails on my platform, C
636 says the behavior is undefined.
637 * src/AnnotationList.c (AnnotationList__insertInto): Remove
638 FIXME. Use new id field of InadequacyList nodes rather than
639 their memory addresses when sorting.

657 Fix handling of yychar manipulation in user semantic actions.
658 The problem was that yacc.c didn't always update the yychar
659 translation afterwards. However, other skeletons appear to be
660 fine. glr.c appears to already translate yychar before every
661 use. lalr1.cc does not define yychar and does not document its
662 replacement, yyla, for users. It does provide yyclearin, but
663 that does not manipulate yyla and thus requires no translation
664 update. In lalr1.java, yychar is out of scope during semantic
665 actions.
666 * NEWS (2.5): Document.
667 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
668 yytoken here.
669 (yyparse, yypush_parse): Instead, translate before every use of
670 yytoken, and add comments explaining this approach.
671 * tests/actions.at (Destroying lookahead assigned by semantic
672 action): New test group checking that translation happens before
673 lookahead destructor calls at parser return. Previously,
674 incorrect destructors were called.
675 * tests/conflicts.at (parse.error=verbose and consistent
676 errors): New test group checking that translation happens at
677 syntax error detection before the associated verbose error
678 message and the associated lookahead destructor calls. While
679 the destructor call is fixed by this patch, the verbose error
680 message is currently incorrect due to another bug (see
681 comments in test group), so this is an expected failure for now.

874 yysyntax_error: avoid duplicate lookahead collection.
875 Except when memory reallocation is required, this change
876 eliminates the need to invoke yysyntax_error twice and thus to
877 repeat the collection of lookaheads. It also prepares for
878 future extensions that will make those repetitions more
879 expensive and that will require additional memory management in
880 yysyntax_error. Finally, it fixes an obscure bug already
881 exercised in the test suite.
882 * data/yacc.c (yysyntax_error): Add arguments for message
883 buffer variables stored in the parser. Instead of size, return
884 status similar to yyparse status but indicating success of
885 message creation. Other than the actual reallocation of the
886 message buffer, import and clean up memory management code
887 from...
888 (yyparse, yypush_parse): ... here.
889 * tests/regression.at (parse.error=verbose overflow): No longer

902
903 benchmarks: use %debug consistently among grammars.
904 * etc/bench.pl.in (generate_grammar_triangular): Do not activate
905 %debug by default. It can affect the timings even if yydebug=0.
906 (generate_grammar_calc): For consistency with other grammars,
907 use YYDEBUG environment variable to set yydebug.

922 Use the correct conversion specifier for size_t.
923 Reported by Jim Meyering.
924 * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu"
925 because Sbitset__Index is size_t.
926 * src/Sbitset.c (Sbitset__fprint): Use it instead of %d.

1031 * data/yacc.c: Clean up M4 for readability, and make output
1032 whitespace more consistent. For the main parse function
1033 comment, instead of saying "yyparse or yypush_parse", say either
1034 "yyparse" or "yypush_parse" depending on which it actually is.

1042
1043 lalr1.cc: syntax_error as exceptions.
1044 It is common to use sort of factories in the user actions. These
1045 factories may check some "syntactic" constraints that are not
1046 enforced by the grammar itself. This is possible using YYERROR
1047 within the action itself. Provide the user with a means to throw
1048 a syntax_error exception.
1049
1050 * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
1051 Declare and define yy::parser::syntax_error.

1120 Use "Unresolved reference" error message when no symbols were found
1121 in a symbolic reference resolution. Remove .expr and -expr from
1122 the shown reference when the reference is unresolved.
1123 * src/scan-code.l: Change the error message, adjust location columns,
1124 rename variable "exact_mode" to "explicit_bracketing".
1125 * tests/named-ref.at: Adjust existing tests and add a new one.
1126
1127 2009-09-04 Akim Demaille <demaille@gostai.com>
1128
1129 Adjust synclines in src/parse-gram.[ch].

1131 with ylwrap) when this wrapper is used to compile
1132 src/parse-gram.y.
1133
1134 2009-09-03 Joel E. Denny <jdenny@clemson.edu>

1148 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
1149
1150 Don't suppress warnings about unused parse.error.
1151 * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
1152 %define variable parse.error unless b4_error_verbose_flag is
1153 actually expanded in a skeleton.
1154
1155 2009-09-03 Akim Demaille <demaille@gostai.com>

1167 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
1168 See
1169 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
1170 * src/scan-code.h (code_props_rule_action_init): Rename
1171 named_ref arg to name so it doesn't shadow named_ref type. This
1172 makes it consistent with the function definition in scan-code.l
1173 anyway.
1174
1175 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
1176

1213 Avoid compiler warning.
1214
1215 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
1216
1217 tests: use perl for printing special sequences to files.
1218 And skip tests if perl is not available. This is better than
1219 playing tricks with shell portability. Suggested by Akim
1220 Demaille.
1221 * tests/input.at (Bad character literals): Use it here for
1222 omitting final newlines.
1223 (Bad escapes in literals): Use it here for special characters.
1224
1225 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1226
1227 tests: show a use of %define lr.default-reductions "consistent"
1228 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
1229 prevents the omission of expected tokens for %error-verbose.
1230
1231 2009-08-26 Akim Demaille <demaille@gostai.com>
1232
1233 tests: portability fix.
1234 * tests/input.at (Bad escapes in literals): Don't expect "echo
1235 '\0'" to output \ then 0.
1236
1237 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1238
1239 Actually handle the yytable zero value correctly this time.
1240 * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
1241 zero values in the YYTABLE comments.
1242 * data/glr.c (yytable_value_is_error): Don't check for zero
1243 value.
1244 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
1245 * data/yacc.c (yytable_value_is_error): Likewise.
1246 * data/lalr1.java (yy_table_value_is_error_): Likewise.
1247 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
1248 * src/tables.h: In header comments, explain why it's useless to
1249 check for a zero value in yytable.
1250
1251 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1252
1253 More fixes related to last two patches.
1254 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
1255 comments: zero indicates syntax error not default action.
1256 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
1257 defined.
1258 * data/glr.c (yyis_pact_ninf): Rename to...
1259 (yypact_value_is_default): ... this.
1260 (yyisDefaultedState): Update for rename.
1261 (yyis_table_ninf): Rename to...
1262 (yytable_value_is_error): ... this, and check for value zero
1263 besides just YYTABLE_NINF.
1264 (yygetLRActions): Check for default value from yypact. It
1265 appears that this check is always performed before this function
1266 is invoked, and so adding the check here is probably redundant.
1267 However, the code may evolve after this subtlety is forgotten.
1268 Also, update for rename to yytable_value_is_error. Because that
1269 macro now checks for zero, a different but equivalent branch of
1270 the if-then-else here is evaluated.
1271 (yyreportSyntaxError): Update for rename to
1272 yytable_value_is_error. The zero condition was mishandled
1273 before.
1274 (yyrecoverSyntaxError): Update for renames. No behavioral
1275 changes.
1276 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
1277 New function.
1278 (yy_table_value_is_error_): New function.
1279 (parse): Use new functions where possible. No behavioral
1280 changes.
1281 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
1282 The zero condition was mishandled before.
1283 * data/yacc.c (yyis_pact_ninf): Rename to...
1284 (yypact_value_is_default): ... this.
1285 (yyis_table_ninf): Rename to...
1286 (yytable_value_is_error): ... this, and check for value zero
1287 besides just YYTABLE_NINF.
1288 (yysyntax_error): Update for rename to yytable_value_is_error.
1289 The zero condition was mishandled before.
1290 (yyparse): Update for renames. No behavioral changes.
1291 * src/tables.h: Improve comments about yypact, yytable, etc.
1292 more. Most importantly, say yytable value of zero means syntax
1293 error not default action.
1294
1295 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1296
1297 Fix %error-verbose for conflicts resolved by %nonassoc.

1301 * data/yacc.c (yysyntax_error): Likewise.
1302 * data/lalr1.cc (yysyntax_error_): Fix this by checking
1303 yytable_ninf_.
1304 * data/lalr1.java (yysyntax_error): Likewise.
1305 * tests/conflicts.at (%nonassoc and eof): Update expected output
1306 and remove FIXME.

1311 * data/c.m4 (b4_table_value_equals): New macro to capture
1312 some repeated code.
1313 * data/glr.c (yyis_pact_ninf): Use it here.
1314 (yyis_table_ninf): Likewise.
1315 (yyreportSyntaxError): Improve internal comments.
1316 * data/yacc.c (yyis_pact_ninf): New macro copied from glr.c.
1317 Use it everywhere possible.
1318 (yyis_table_ninf): Likewise.
1319 (yysyntax_error): Improve internal comments.
1320 * data/lalr1.cc (yysyntax_error_): Likewise.
1321 * data/lalr1.java (yysyntax_error): Likewise.
1322 * src/tables.h: Improve comments about yypact, yytable, etc.
1323
1324 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
1325
1326 Use locale when quoting.
1327 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
1328 quote rather than implementing quoting here.
1329
1330 2009-08-20 Eric Blake <ebb9@byu.net>
1331
1332 Make previous patch more robust.
1333 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
1334 argmatch.h.
1335 (output_skeleton): Use it.
1336 Suggested by Akim Demaille.
1337
1338 Import latest m4/m4.m4.
1339 * submodules/autoconf: Update to autoconf 2.64.
1340 * configure.ac (M4_GNU_OPTION): New define.
1341 * src/output.c (output_skeleton): Use it to resolve FIXME.
1342 * NEWS: Mention this.
1343
1344 2009-08-19 Joel E. Denny <jdenny@clemson.edu>

1346 Fix complaints about escape sequences.
1347 Discussed starting at
1348 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
1349 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
1350 For a \0 and similar escape sequences meaning the null
1351 character, report an invalid escape sequence instead of an
1352 invalid null character because the latter does not actually
1353 appear in the user's input.
1354 In all escape sequence complaints, don't escape the initial
1355 backslash, and don't quote when the sequence appears at the end
1356 of the complaint line unless there's whitespace that quotearg
1357 won't escape.
1358 Consistently say "invalid" not "unrecognized".
1359 Consistently prefer "empty character literal" over "extra
1360 characters in character literal" warning for invalid escape
1361 sequences; that is, consistently discard those sequences.
1362 * tests/input.at (Bad escapes in literals): New.

1377 variables: simplify the upgrade of namespace into api.namespace.
1378
1379 This patch simplifies "variables: rename namespace as
1380 api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.

1385 (muscle_percent_define_insert): Use it in replacement of the
1386 previous tr invocation.
1387 Remove variable_tr, no longer needed.
1388 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
1389 Remove.
1390 * data/c++.m4: No longer handle namespace -> api.namespace.
1391 * tests/input.at (%define backward compatibility): Check that

1407
1408 2009-08-19 Akim Demaille <demaille@gostai.com>
1409
1410 lalr1.cc: get rid of yyparse's yystate.
1411 yystate and yystack_[0].state are equal, keep only the latter.
1412 The former was also used as a temporary variable to compute the
1413 post-reduction state. Move this computation into an auxiliary
1414 function.
1415
1416 * data/glr.c (yyLRgotoState): Fuse variable definition and first
1417 assignment.
1418 * data/lalr1.cc (yy_lr_goto_state_): New.
1419 (yyparse): Use it.
1420 Replace remaining uses of yystate by yystate_[0].state.
1421 Remove the former.
1422
1423 2009-08-19 Akim Demaille <demaille@gostai.com>
1424
1425 lalr1.cc: destroy $$ when YYERROR is called.
1426 * data/lalr1.cc (yyreduce): Compute the resulting state before
1427 running the user action so that yylhs is a valid symbol.
1428 (yyerrorlab): Since yylhs is complete (it knows its type), we can
1429 simply call yy_destroy_ to destroy $$ on YYERROR invocations.
1430 * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.

1452 build: lower gettext requirements.
1453
1454 Bison was uselessly requiring the formatstring macros from
1455 gettext, which resulted in mo files not being installed on systems
1456 that perfectly supported Bison mo files. Lower the requirement.
1457 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html

1479 * src/reader.c (check_and_convert_grammar): Don't add any
1480 symbols after the first symbols_do invocation.
1481 * src/symtab.c (symbols_sorted): New static global.
1482 (user_token_number_redeclaration): Update comments.

1484 that symbols_sorted hasn't been allocated yet.
1485 (symbols_free): Free symbols_sorted.
1486 (symbols_cmp, symbols_cmp_qsort): New functions.
1487 (symbols_do): Sort symbol_table into symbols_sorted on first

1489 * tests/input.at (Numbered tokens): Recombine tests now that the
1490 output should be deterministic across multiple numbers.

1500 build: fix the generation of the documentation.
1501 Some of our targets use "bison --help", but they can't depend on
1502 "bison" itself (to avoid additional requirements on the user), so
1503 they used to call "make src/bison" in the commands. Then
1504 concurrent builds may fail: one make might be aiming one of its
1505 jobs at compiling src/bison, and another job at generating the man
1506 page. If the latter is faster than the former, then we have two
1507 makes that concurrently try to compile src/bison.
1508
1509 This might also be a more convincing explanation for the failure
1510 described in the patch "build: fix paths".
1511
1512 * Makefile.am (SUFFIXES): Initialize.
1513 * build-aux/move-if-change: New, symlink to gnulib's.

1531 Adjust more variables.
1532 * etc/prefix-gnulib-mk (prefix_assignment): Don't rename

1541 build: fix paths.
1542 When using $(top_builddir) inconsistently, Make (including GNU
1543 Make) is sometimes confused. As a result it may want to build
1544 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
1545 file, different names) concurrently, which, amusingly enough,
1546 might end with:
1547
1548 ranlib lib/libbison.a
1549 ranlib lib/libbison.a
1550 make[2]: *** [lib/libbison.a] Segmentation fault
1551

1553

1569 Miscellaneous code readability improvements.
1570
1571 * src/reader.c (reader): Move %define front-end variable
1572 defaults and checking into...
1573 (prepare_percent_define_front_end_variables): ... this new
1574 function.
1575
1576 * src/scan-gram.l (INITIAL): For consistency with string
1577 literals, don't store open quote on character literal. It's
1578 discarded before returning anyway.
1579 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
1580 Make length test more readable, and make the character stored
1581 for an empty literal more obvious while consistent with the
1582 previous behavior.
1583
1584 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
1585 USER_NUMBER_HAS_STRING_ALIAS throughout.
1586 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
1587 that is repeated in symtab.h. Improve argument names to make it
1588 clear which side of the symbol-string alias pair is which.
1589 (symbol_check_alias_consistency): Improve local variable names
1590 for the same purpose.
1591 * src/symtab.h (struct symbol): Make comments about aliases
1592 clearer.
1593 (symbol_make_alias): Improve comments and argument name.
1594 * src/output.c (token_definitions_output): Update for rename to
1595 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.

1662 Pacify "gcc -Wunused" for the input function from Flex.
1663 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
1664 and later.
1665 * src/scan-code.l: Add "%option noinput", which I cannot find in
1666 the Flex manual, but which Flex has supported since at least as
1667 far back as 2.5.4. However, if any of our developers still use
1668 Flex 2.5.4, they'll need to stop configuring with
1669 --enable-gcc-warnings because "%option noinput" didn't work
1670 correctly until Flex 2.5.6.

1716 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
1717 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
1718 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
1719 arguments are not needed because of the following changes.
1720 Fix stale comments.
1721 Bison developers should use GNU M4 and should not use
1722 POSIXLY_CORRECT when building the test suite, so do not

1765 Not only this is inefficient, this also builds incorrect sources

1783 Make "simple" its default value.
1784 Check the valid values.
1785 * src/parse-gram.y: Use %define parse.error.

1800 * src/parse-gram.y: Add new syntax (named_ref.opt).
1801 * src/reader.c: Store named refs in symbol lists.
1802 * src/reader.h: New argument for symbol_append and
1803 action_append functions.
1804 * src/scan-code.h: Add new field (named_ref) into
1805 code_props data structure. Keeps named ref of midrule
1806 actions.
1807 * src/scan-code.l: Support for named refs in semantic
1808 action code. New function 'parse_named_ref'.
1809 * src/scan-gram.l: Support bracketed id.
1810 * src/symlist.c: Store named refs in symbol lists.

1874 deterministic test suite.
1875 Some consistency checks on symbols are performed after all the
1876 symbols were read, by an iteration over the symbol table. This
1877 traversal is nondeterministic, which can be a problem for test
1878 cases.
1879 Avoid this.
1880 Addresses another form of nondeterminism reported by Joel E. Denny.
1881 http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00023.html
1882

1966 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
1967
1968 Handle a trailing `:' in a user-supplied C++ namespace better.
1969 * data/c++.m4 (b4_namespace_close): Don't let it be printed
1970 among the closing braces here. This fix might make the
1971 generated code easier to debug, but otherwise it should be
1972 insignificant because a trailing `:' is a C++ error already.
1973
1974 2009-05-19 Akim Demaille <demaille@gostai.com>
1975
1976 remove useless variable.
1977 * src/getargs.c (skeleton_arg): Remove now useless variable.

2045 * src/files.c (tr): Move to...
2046 * src/getargs.c, src/getargs.h (tr): ... here because I can't
2047 think of a better place to expose it. My logic is that, for all

2049 getargs.h is already included.

2152 (Language and Grammar): Bison is no longer limited to LALR(1)
2153 restrictions.
2154 (GLR parsing): Say deterministic or LR(1) rather than LALR(1)
2155 when trying to distinguish from GLR. Talk about LR(1) grammars

2199 (set_goto_map): Export it.
2200 (map_goto): Export it.
2201 (compute_lookahead_tokens): Don't free goto_follows yet. Now
2202 handled in ielr.
2203 (initialize_LA): Export it. Move lookback allocation to...
2204 (lalr): ... here because, for canonical LR, initialize_LA must
2205 be invoked but lookback and much of the rest of LALR isn't
2206 needed.
2207 * main.c (main): Instead of lalr, invoke ielr, which invokes
2208 lalr.
2209 * src/reader.c (reader): Default lr.type to "LALR".
2210 Default lr.default_rules to "accepting" if lr.type is "canonical

2482 This allows to pass -Derror_verbose on the command line. Better
2483 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
2484 ERROR_VERBOSE being defined as false or true.
2485 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
2486 on b4_percent_define_ifdef, for does not check the defined value,
2487 but only whether the symbol is defined, rely on

2503 and discussed again starting at
2504 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
2505 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
2506 because location information is bogus.
2507 Use angle brackets to delimit fake file name because square brackets
2508 look like underexpanded m4. Choose a better fake file name.
2509 Use negative line numbers.
2510 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
2511 * src/location.c (location_print): If line for a boundary is negative,
2512 only print that boundary's file name.

2556 * data/location.cc: Update copyright years.
2557 (Position::operator==): Use parens to make precedence explicit.
2558 Compare lines and columns first, as they are more likely to be

2697
2698 2009-02-19 Akim Demaille <demaille@gostai.com>
2699
2700 Make yyparser::error public.
2701 * data/lalr1.cc: here.
2702 There is no good reason to keep it private (and it is convenient
2703 to use it from the scanner for instance). It is already public in
2704 glr.cc.

2713 Remove trailing blanks.
2714 The epilogue has its own ending \n, no need to add another.
2715
2716 * data/glr.c, data/lalr1.java, data/yacc.c: dnl when outputing the
2717 epilogue.
2718 * data/glr.cc: dnl when extending the epilogue.

2789
2790 Propagate i18n changes into glr.c.
2791 * TODO: Update.
2792 * data/glr.c (yyreportSyntaxError): Use "switch" instead of
2793 building the error message format dynamically.
2794 * data/lalr1.java: Formatting changes.
2795
2796 2008-12-11 Akim Demaille <demaille@gostai.com>
2797
2798 Use testsuite -C.
2799 * tests/local.mk: Replace "cd && testsuite" by "testsuite -C".

2811 2008-12-08 Akim Demaille <demaille@gostai.com>
2812
2813 Fix portability issue in the test suite.
2814 * tests/local.at (AT_MATCHES_CHECK): New.
2815 Based on Perl instead of Sed. Sed has too many portability
2816 pitfalls, not ever Sed is GNU Sed.
2817 * tests/actions.at (Fix user actions without a trailing semicolon):
2818 Use it.
2819
2820 2008-12-08 Akim Demaille <demaille@gostai.com>
2821
2822 Update data/README.
2823 * data/README: Document glr.cc, lalr1.java, m4sugar and xslt.
2824
2825 2008-12-08 Akim Demaille <demaille@gostai.com>
2826
2827 Install autoconf as a submodule to get m4sugar.
2828 * .gitmodules: Add submodules/autoconf.

2844
2845 Fix regeneration of atconfig.
2846 * tests/local.mk (tests/atconfig): The rule was incorrect, but
2847 remove it: now that there is no tests/Makefile.am, the top-level
2848 Makefile properly updates atconfig when needed.
2849
2850 2008-12-07 Di-an Jan <dianj@freeshell.org>
2851
2852 Implement the FIXME that ends an user action with a semicolon
2853 if it seems necessary.
2854 * src/scan-code.l (flex rules section): Flag cpp directive from
2855 any `#' to the first unescaped end-of-line. Semicolon is not
2856 needed after `;', `{', '}', or cpp directives and is needed after
2857 any other token (whitespaces and comments have no effect).
2858 * tests/actions.at (Fix user actions without a trailing semicolon):
2859 New test.
2860 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
2861 to make user actions complete statements.
2862 Adjust column numbers in error messages.
2863 * tests/regression.at (Fix user actions without a trailing semicolon):
2864 Remove. Covered by new test.
2865
2866 2008-12-07 Akim Demaille <demaille@gostai.com>
2867
2868 Update gnulib.

2875 function.
2876
2877 2008-12-02 Eric Blake <ebb9@byu.net>
2878
2879 Build testsuite with newer autoconf.
2880 * tests/output.at (m4_expand): Don't override in newer autoconf,
2881 where the underlying implementation changed.
2882 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
2883 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
2884 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
2885 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
2886 since some of them contain unbalanced ')'.
2887
2888 2008-12-01 Akim Demaille <demaille@gostai.com>
2889
2890 Use b4_symbol for printers and destructors everywhere.
2891 * data/bison.m4 (b4_symbol_action_location): New.
2892 * data/c.m4 (b4_symbol_actions): Remove.
2893 Adjust all callers to use by b4_symbol_foreach and the corresponding
2894 b4_symbol_printer/destructor macro.
2895 * data/glr.cc: Adjust.
2896 * data/lalr1.java: Adjust the %destructor sanity check.
2897 * src/output.c (symbol_code_props_output): Remove, we no longer
2898 need the b4_symbol_printers/destructors tables.
2899
2900 2008-12-01 Akim Demaille <demaille@gostai.com>
2901
2902 Use b4_symbol_case_.
2903 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
2904 b4_symbol_case_.
2905
2906 2008-12-01 Akim Demaille <demaille@gostai.com>
2907
2908 Move b4_symbol based macro to bison.m4.
2909 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
2910 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
2911 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
2912 (b4_type_foreach): Move to...
2913 * data/bison.m4: Here.
2914 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
2915 b4_symbol_value_template instead of b4_symbol_value.
2916
2917 2008-12-01 Akim Demaille <demaille@gostai.com>
2918
2919 b4_symbol/type_foreach.
2920 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
2921 Use them.
2922
2923 2008-12-01 Akim Demaille <demaille@gostai.com>
2924
2925 Use the symbol properties to output the printer/destructor for lalr1.cc.
2926 Instead of defining complex list of tuples to define various
2927 properties of the symbols, we now prefer to define symbols as
2928 "structs" in m4: using the symbol key (its number), and the
2929 property name, b4_symbol gives it value. Use this to handle
2930 destructors and printers.
2931
2932 * src/output.c (CODE_PROP): New.
2933 (prepare_symbol_definitions): Use it to define the printer and
2934 destructor related attributes of the symbols.
2935 * data/lalr1.cc (b4_symbol_actions): Rename as...
2936 (b4_symbol_action): this.
2937 Use b4_symbol instead of 6 arguments.
2938 (b4_symbol_printer, b4_symbol_destructor): New.
2939 Use them instead of b4_symbol_actions.
2940
2941 2008-12-01 Akim Demaille <demaille@gostai.com>
2942
2943 Avoid capturing variables too easily.
2944 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
2945 v__ and p__ instead of v and p.
2946
2947 2008-12-01 Akim Demaille <demaille@gostai.com>
2948
2949 Remove spurious empty line before syncline.
2950 * data/bison.m4 (b4_syncline): Don't output an empty line before
2951 the output.
2952
2953 2008-11-26 Akim Demaille <demaille@gostai.com>
2954
2955 Convert lib/Makefile.am into lib/local.mk.
2956 The real problem is rather gnulib.mk, which itself is extracted
2957 from a Makefile.am that gnulib expects to the "recursive". The
2958 tool prefix-gnulib-mk converts such a gnulib.mk to be
2959 non-recursive. Also, some AC_SUBST variables need to be adjusted.
2960
2961 * etc/prefix-gnulib-mk: New.
2962 * bootstrap (slurp): Use it to convert further gnulib.mk.
2963 No longer try to avoid re-creation of lib/gnulib.mk as the changes
2964 are deeper.
2965 * lib/Makefile.am: Rename as...
2966 * lib/local.mk: this.
2967 Adjust to be prefixed.
2968 * Makefile.am, configure.ac: Adjust.
2969 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
2970
2971 2008-11-26 Akim Demaille <demaille@gostai.com>
2972
2973 s/_FLAGS/FLAGS/.
2974 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
2975 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
2976 Reported by Eric Blake.
2977
2978 2008-11-26 Akim Demaille <demaille@gostai.com>
2979
2980 Use b4_parser_tables_define in glr.cc.
2981 * data/glr.c: Use b4_parser_tables_define instead of defining the
2982 (deterministic integral) tables by hand.
2983
2984 2008-11-26 Akim Demaille <demaille@gostai.com>
2985
2986 Use b4_parser_tables_define in Java.
2987 * data/java.m4 (b4_typed_parser_table): Rename as...
2988 (b4_typed_parser_table_define): this, for consistency.
2989 Accept a comment as $4.
2990 Move $2 into yy*_.
2991 (b4_integral_parser_table): Rename as...
2992 (b4_integral_parser_table_define): this.
2993 * data/lalr1.java: Adjust all uses.
2994 Use b4_parser_tables_define instead of generation by hand.
2995
2996 2008-11-26 Akim Demaille <demaille@gostai.com>
2997
2998 Prepare the convergence bw C style and Java table generation.
2999 * data/bison.m4 (b4_tables_map, b4_tables_declare)
3000 (b4_tables_define): Rename as...
3001 (b4_integral_parser_tables_map, b4_parser_tables_declare)
3002 (b4_parser_tables_define): these.
3003 * data/c.m4 (b4_table_define): Rename as...
3004 (b4_integral_parser_table_define): this.
3005 * data/lalr1.cc: Adjust.
3006 (b4_table_define, b4_table_declare): Rename as...
3007 (b4_integral_parser_table_define)
3008 (b4_integral_parser_table_declare): these.
3009 (yyrline_): Move the comment where it is actually used.
3010 * data/yacc.c: Adjust.
3011 (yyrline): Use b4_integral_parser_table_define.
3012
3013 2008-11-26 Akim Demaille <demaille@gostai.com>
3014
3015 Regen.
3016 * src/parse-gram.h, src/parse-gram.c: Regen.
3017
3018 2008-11-26 Akim Demaille <demaille@gostai.com>
3019
3020 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.
3021 * data/lalr1.cc (b4_tables_map): Move to...
3022 * data/bison.m4: here.
3023 Update the comment for yytable during the flight.
3024 (b4_tables_declare, b4_tables_define): New.
3025 * data/lalr1.cc: Use them.
3026 * data/c.m4 (b4_table_define): New.
3027 * data/yacc.c: Use b4_tables_define instead of output the tables
3028 by hand.
3029 * tests/regression.at (Web2c Actions): Adjust the expected output,
3030 the order of the tables changed.
3031
3032 2008-11-26 Akim Demaille <demaille@gostai.com>
3033
3034 Get rid of (yy)rhs and (yy)prhs.
3035 These tables are no longer needed in the parsers, and they don't seem to
3036 be useful. They are not documented either.
3037
3038 * src/output.c (prepare_rules): Get rid of rhs and prhs.
3039 Adjust the computation of (yy)r2.
3040
3041 2008-11-26 Akim Demaille <demaille@gostai.com>
3042
3043 Rule length is unsigned.
3044 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
3045
3046 2008-11-26 Akim Demaille <demaille@gostai.com>
3047
3048 Get rid of lalr1-split.cc.
3049 It was no longer maintainer.
3050
3051 * data/lalr1-split.cc: Remove.
3052 * etc/bench.pl.in (bench_fusion_parser): Remove.
3053 Adjust.
3054
3055 2008-11-26 Akim Demaille <demaille@gostai.com>
3056
3057 Use yy* consistently.
3058 * data/glr.c: Now that yyrhs no longer exists as a global
3059 variable, rename local "rhs" variables into "yyrhs" for
3060 consistency.
3061
3062 2008-11-25 Akim Demaille <demaille@gostai.com>
3063
3064 Get rid of yyrhs and yyprhs in glr.c.
3065 * data/glr.c (yyrhs, yyprhs): Remove.
3066 Instead, use the state stack and yystos.
3067
3068 2008-11-25 Akim Demaille <demaille@gostai.com>
3069
3070 Flag glr tests.
3071 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
3072 as an Autotest keyword.
3073
3074 2008-11-25 Akim Demaille <demaille@gostai.com>
3075
3076 Prefer TESTSUITE_FLAGS.
3077 TESTSUITEFLAGS is barely readable.
3078
3079 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
3080 for backward compatibility.
3081 Use the former instead of the latter.
3082
3083 2008-11-25 Akim Demaille <demaille@gostai.com>
3084
3085 Get rid of yyrhs and yyprhs in larl1.java.
3086 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
3087 (yy_reduce_print): Rather, use yystos_ and the state stack.
3088
3089 2008-11-25 Akim Demaille <demaille@gostai.com>
3090
3091 Formatting changes.
3092
3093 2008-11-25 Akim Demaille <demaille@gostai.com>
3094
3095 Get rid of yyrhs and yyprhs in yacc.c.
3096 They were used to get the symbol types, given a rule number, when
3097 displaying the top of the stack before a reduction. But the
3098 symbol type is available from the state stack. This has two be
3099 benefits: two tables less in the parser (making it smaller), and a
3100 more consistent use of the three stacks which will help to fuse
3101 them.
3102
3103 * data/yacc.c (yyprhs, yyrhs): Remove.
3104 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
3105 (yy_reduce_print): Take yyssp as argument.
3106 Use it, together with yystos, to get the symbol type.
3107 * tests/regression.at (Web2c Report): Remove these tables from the
3108 expected output.
3109
3110 2008-11-25 Akim Demaille <demaille@gostai.com>
3111
3112 b4_tables_map.
3113 The point is to factor the generation of the tables across skeletons.
3114 This is language dependant.
3115
3116 * data/c.m4 (b4_comment_): New.
3117 Should be usable to define how to generate tables independently of
3118 the language.
3119 (b4_c_comment): New.
3120 (b4_comment): Bounce to b4_c_comment.
3121 Now support $2 = [PREFIX] for indentation.
3122 * data/lalr1.cc (b4_table_declare): Don't output a comment if
3123 there is no comment.
3124 Indent it properly when there is one.
3125 Output the ending semicolon.
3126 (b4_table_define): Space changes.
3127 Output the ending semicolon.
3128 (b4_tables_map): New.
3129 Use it twice instead of declaring and defining the (integral)
3130 tables by hand.
3131
3132 2008-11-25 Akim Demaille <demaille@gostai.com>
3133
3134 b4_table_declare.
3135 * data/lalr1.cc (b4_table_declare): New.
3136 Use it to declare the tables defined with b4_table_define.
3137 (b4_table_define): Declare a third arg to match b4_table_declare
3138 signature.
3139 Move all the comments around invocations of b4_table_define into
3140 the invocations itselves.
3141 Move things around to have the order for declarations and

3296 Support parametric types.
3297
3298 There are two issues to handle: first scanning nested angle
3299 bracket pairs to support types such as std::pair< std::string,
3300 std::list<std::string> > >.
3301
3302 Another issue is to address idiosyncracies of C++: do not glue two
3303 closing angle brackets together (otherwise it's operator>>), and
3304 avoid sticking blindly a TYPE to the opening <, as it can result
3305 in '<:' which is a digraph for '['.
3306
3307 * src/scan-gram.l (brace_level): Rename as...
3308 (nesting): this.
3309 (SC_TAG): New.
3310 Implement support for complex tags.

3312 , but not <.

3314 (b4_symbol_variant): Leave space around types as parameters.

3316 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):

3318 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
3319 * tests/c++.at: Test parametric types.

3323 Test token.prefix.
3324 This is not sufficient, but we test at least that the make_SYMBOL
3325 interface is not affected by token.prefix. A more general test
3326 will be implemented when the support of token.prefix is generalized
3327 to more skeletons.
3328
3329 * tests/c++.at: One more variant test, using token.prefix.

3403 Move sc_tight_scope into maint.mk.
3404 It does not work, and I don't know how it was supposed to work: it
3405 seems to be looking for sources in the build tree. I just moved
3406 it at a better place, fixing it is still required.
3407
3408 * src/local.mk (echo): Remove.

3423 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
3424 (AM_CPPFLAGS): Find find in builddir/src.
3425 (YACC): Move the flags into...
3426 (AM_YFLAGS): here.
3427 * maint.mk (sc_tight_scope): Disable.
3428 It used to bounce to the version in src/Makefile.am which is now
3429 part of this very Makefile.
3430 * Makefile.am, configure.ac: Adjust.
3431 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
3432 include "..." to find files "here": we are no longer in src/, so
3433 qualify the includes with src/.
3434 * doc/Makefile.am (PREPATH): No longer include the top_builddir
3435 prefix.
3436 (.x.1): Adjust to be able to create src/foo from the top level
3437 Makefile, instead of going bounce to src/Makefile the creation of
3438 foo.

3464 examples/calc++/Makefile.am might be interesting to keep as is, since
3465 it is an example in itself.

3484
3485 Provide convenience constructors for locations and positions.
3486 * data/location.cc (position::position): Accept file, line and
3487 column as arguments with default values.
3488 Always qualify initial line and column literals as unsigned.
3489 (location::location): Provide convenience constructors.
3490
3491 2008-11-15 Akim Demaille <demaille@gostai.com>
3492
3493 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
3494 token type.
3495 Using template buys us nothing, and makes it uselessly complex to
3496 construct a symbol. Besides, it could not be generalized to other
3497 languages, while make_FOO would work in C/Java etc.
3498
3499 * data/lalr1.cc (b4_symbol_): New.
3500 (b4_symbol): Use it.
3501 (b4_symbol_constructor_declaration_)
3502 (b4_symbol_constructor_definition_): Instead of generating
3503 specializations of an overloaded template function, just generate
3504 several functions whose names are forged from the token names
3505 without the token.prefix.
3506 (b4_symbol_constructor_declarations): Generate them for all the
3507 symbols, not just by class of symbol type, now that instead of
3508 specializing a function template by the token, we generate a
3509 function named after the token.
3510 (b4_symbol_constructor_specialization_)
3511 (b4_symbol_constructor_specializations): Remove.
3512 * etc/bench.pl.in: Adjust to this new API.
3513
3514 2008-11-13 Akim Demaille <demaille@gostai.com>
3515
3516 %define token.prefix.
3517 Provide a means to add a prefix to the name of the tokens as
3518 output in the generated files. Because of name clashes, it is
3519 good to have such a prefix such as TOK_ that protects from names
3520 such as EOF, FILE etc. But it clutters the grammar itself.
3521
3522 * data/bison.m4 (token.prefix): Empty by default.
3523 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
3524 * data/lalr1.cc (b4_symbol): Ditto.

3534 symbol::token.
3535 This allows the user to get the type of a token returned by yylex.
3536
3537 * data/lalr1.cc (symbol::token): New.
3538 (yytoknum_): Define when %define lex_symbol, independently of
3539 %debug.
3540 (yytoken_number_): Move into...
3541 (symbol::token): here, since that's the only use.
3542 The other one is YYPRINT which was not officially supported
3543 by lalr1.cc, and anyway it did not work since YYPRINT uses this
3544 array under a different name (yytoknum).

3560 yytranslate and yytoknum tables.

3563
3564 Define make_symbol in the header.
3565 To reach good performances these functions should be inlined (yet
3566 this is to measure precisely). To this end they must be available
3567 to the caller.
3568
3569 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
3570 location_type with the class name.
3571 Since will now be output in the header, declare "inline".
3572 No longer use b4_symbol_constructor_specializations, but
3573 b4_symbol_constructor_definitions in the header.
3574 Don't call it in the *.cc file.
3575
3576 2008-11-13 Akim Demaille <demaille@gostai.com>
3577
3578 Define yytranslate in the header for lex_symbol.
3579 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
3580 into the header file when using %define lex_symbol.
3581 (yytranslate_): Declare inline.
3582
3583 2008-11-13 Akim Demaille <demaille@gostai.com>
3584
3585 Define the constructors of symbol_type in
3586 b4_symbol_constructor_definitions.
3587 The constructors are called by the make_symbol functions, which a
3588 forthcoming patch will move elsewhere. Hence the interest of
3589 putting them together.
3590
3591 The stack_symbol_type does not need to be moved, it is used only
3592 by the parser.
3593
3594 * data/lalr1.cc: Move symbol_type and symbol_base_type
3595 constructors into...
3596 (b4_symbol_constructor_definitions): here.
3597 Adjust.
3598
3599 2008-11-13 Akim Demaille <demaille@gostai.com>
3600
3601 Make it easier to move the definition of yytranslate_.
3602 Forthcoming changes will make it possible to use yytranslate_
3603 from outside the parser implementation file.
3604
3605 * data/lalr1.cc (b4_yytranslate_definition): New.
3606 Use it.
3607
3608 2008-11-13 Akim Demaille <demaille@gostai.com>
3609
3610 Remove useless class specification.
3611 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
3612 to refer to the class name to use a type defined by the class for
3613 arguments of member functions.

3617 Finer input type for yytranslate.
3618 This patch is debatable: the tradition expects yylex to return an int
3619 which happens to correspond to token_number (which is an enum). This
3620 allows for instance to return characters (such as '*' etc.). But this
3621 goes against the stronger typing I am trying to have with the new
3622 lex interface which return a symbol_type. So in this case, feed
3623 yytranslate_ with a token_type.
3624
3625 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
3626 expect a token_type.
3627
3628 2008-11-13 Akim Demaille <demaille@gostai.com>
3629
3630 Honor lex-params in %define lex_symbol mode.
3631 * data/lalr1.cc: Use b4_lex_param.

3636 * src/output.c (symbol_definitions_output): Rename symbol
3637 attributes type_name and has_type_name as type and has_type.
3638 * data/lalr1.cc: Adjust uses.
3639
3640 2008-11-13 Akim Demaille <demaille@gostai.com>
3641
3642 Use b4_type_names for the union type.
3643 The union used to compute the size of the variant used to iterate
3644 over the type of all the symbols, with a lot of redundancy. Now
3645 iterate over the lists of symbols having the same type-name.
3646
3647 * data/lalr1.cc (b4_char_sizeof_): New.
3648 (b4_char_sizeof): Use it.
3649 Adjust to be called with a list of numbers instead of a single
3650 number.
3651 Adjust its caller for new-line issues.
3652
3653 2008-11-13 Akim Demaille <demaille@gostai.com>
3654
3655 Define the "identifier" of a symbol.
3656 Symbols may have several string representations, for instance if
3657 they have an alias. What I call its "id" is a string that can be
3658 used as an identifier. May not exist.
3659
3660 Currently the symbols which have the "tag_is_id" flag set are
3661 those that don't have an alias. Look harder for the id.
3662
3663 * src/output.c (is_identifier): Move to...
3664 * src/symtab.c (is_identifier): here.
3665 * src/symtab.h, src/symtab.c (symbol_id_get): New.
3666 * src/output.c (symbol_definitions_output): Use it to define "id"
3667 and "has_id".
3668 Remove the definition of "tag_is_id".
3669 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
3670 "tag_is_id" were used to produce code.
3671 We still use "tag" for documentation.
3672

3678 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
3679 (AT_CHECK_NAMESPACE): Check the use of locations.
3680 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
3681 without locations with lalr1.cc.
3682 Test these cases.
3683 * tests/output.at: Check lalr1.cc with and without location
3684 support.
3685 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
3686 Don't use locations.

3799
3800 Introduce make_symbol.
3801 make_symbol provides a means to construct a full symbol (kind,
3802 value, location) in a single shot. It is meant to be a Symbol
3803 constructor, parameterized by the symbol kind so that overloading
3804 would prevent incorrect kind/value pairs. Unfortunately
3805 parameterized constructors do not work well in C++ (unless the
3806 parameter also appears as an argument, which is not acceptable),
3807 hence the use of a function instead of a constructor.
3808
3809 * data/lalr1.cc (b4_symbol_constructor_declaration_)
3810 (b4_symbol_constructor_declarations)
3811 (b4_symbol_constructor_specialization_)

3814 (b4_symbol_constructor_definitions): New.
3815 Use them where appropriate to generate declaration, declaration of
3816 the specializations, and implementations of the templated
3817 overloaded function "make_symbol".
3818 (variant::variant): Always define a default ctor.
3819 Also provide a copy ctor.
3820 (symbol_base_type, symbol_type): New ctor overloads for value-less
3821 symbols.
3822 (symbol_type): Now public, so that functions such as yylex can use
3823 it.

3833
3834 Test 214 was failing: it greps with a pattern containing [ ]*
3835 which obviously meant to catch spaces and tabs, but contained only
3836 spaces. Tabulations in sources are a nuisance, so to simplify the
3837 matter, get rid of all the tabulations in the Java sources. The
3838 other skeletons will be treated equally later.
3839
3840 * data/java.m4, data/lalr1.java: Untabify.
3841 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
3842 tabulations are no longer generated.

4022 Change the handling of the symbols in the skeletons.
4023 Before we were using tables which lines were the symbols and which
4024 columns were things like number, tag, type-name etc. It is was
4025 difficult to extend: each time a column was added, all the numbers had
4026 to be updated (you asked for colon $2, not for "tag"). Also, it was
4027 hard to filter these tables when only a subset of the symbols (say the
4028 tokens, or the nterms, or the tokens that have and external number
4029 *and* a type-name) was of interest.
4030
4031 Now instead of monolithic tables, we define one macro per cell. For
4032 instance "b4_symbol(0, tag)" is a macro name which contents is
4033 self-decriptive. The macro "b4_symbol" provides easier access to
4034 these cells.
4035

4081
4082 Add %precedence support.
4083 Unfortunately it is not possible to reuse the %prec directive. This
4084 is because to please POSIX, we do not require to end the rules with a
4085 semicolon. As a result,
4086
4087 foo: bar %prec baz
4088
4089 is ambiguous: either a rule which precedence is that of baz, or a rule,
4090 and then a declaration of the precedence of the token baz.
4091
4092 * doc/bison.texinfo: Document %precedence.
4093 (Precedence Only): New.

4220 Rely on the state stack to display reduction traces.
4221 To display rhs symbols before a reduction, we used information
4222 about the rule reduced, which required the tables yyrhs and

4334
4335 2008-11-07 Akim Demaille <demaille@gostai.com>
4336
4337 Handle more general types of option arguments.
4338 * build-aux/cross-options.pl: The argument ends at the first
4339 space, not the first non-symbol character.
4340 Use @var for each word appearing the argument description.
4341
4342 2008-11-07 Akim Demaille <demaille@gostai.com>

4349
4350 2008-11-07 Akim Demaille <demaille@gostai.com>
4351
4352 Add "%define assert" to variants.
4353 This is used to help the user catch cases where some value gets
4354 ovewritten by a new one. This should not happen, as this will
4355 probably leak.
4356
4357 Unfortunately this uncovered a bug in the C++ parser itself: the
4358 lookahead value was not destroyed between two calls to yylex. For
4359 instance if the previous lookahead was a std::string, and then an int,
4360 then the value of the std::string was correctly taken (i.e., the
4361 lookahead was now an empty string), but std::string structure itself
4362 was not reclaimed.
4363
4364 This is now done in variant::build(other&) (which is used to take the
4365 value of the lookahead): other is not only stolen from its value, it
4366 is also destroyed. This incurs a new performance penalty of a few
4367 percent, and union becomes faster again.
4368
4369 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
4370 (b4_variant_if): New.
4371 (variant::built): New.
4372 Use it whereever the status of the variant changes.
4373 * etc/bench.pl.in: Check the penalty of %define assert.
4374
4375 2008-11-07 Akim Demaille <demaille@gostai.com>
4376
4377 Use "%define variant" in bench.pl.
4378 * etc/bench.pl.in: No longer use the pseudo directive %variants,
4379 just use %define variants.
4380
4381 2008-11-07 Akim Demaille <demaille@gostai.com>

4647
4648 Fuse the three stacks into a single one.
4649
4650 In order to make it easy to perform benchmarks to ensure that
4651 there are no performance loss, lalr1.cc is forked into
4652 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
4653 lalr1.cc.
4654
4655 Meanwhile, to make sure that lalr1-fusion.cc is correctly
4656 exercized by the test suite, the user must install a symbolic link
4657 from lalr1.cc to it.
4658
4659 Instead of having three stacks (state, value, location), use a
4660 stack of triples. This considerably simplifies the code (and it
4661 will be easier not to require locations as currently does the C++
4662 parser), and also gives a 10% speedup according to
4663 etc/bench (probably mainly since memory allocation is done once
4664 instead of three times).
4665
4666 Another motivation is to make it easier to destruct properly
4667 semantic values: now that they are bound to their state (hence
4668 symbol type) it will be easier to call the appropriate destructor.
4669
4670 These changes should probably benefit the C parser too.
4671
4672 * data/lalr1.cc: Copy as...
4673 * data/lalr1-fusion.cc: this new file.
4674 (b4_rhs_value, b4_rhs_location): New definitions overriding those
4675 from c++.m4.
4676 (state_stack_type, semantic_stack_type, location_stack_type)
4677 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
4678 (data_type, stack_type, yystack_): New.
4679 (YYLLOC_DEFAULT, yypush_): Adjust.
4680 (yyerror_range): Now based on data_type, not location_type.
4681
4682 2008-11-03 Akim Demaille <demaille@gostai.com>
4683
4684 Push the state, value, and location at the same time.
4685 This is needed to prepare a forthcoming patch that fuses the three
4686 stacks into one.
4687
4688 * data/lalr1.cc (parser::yypush_): New.
4689 (parser::yynewstate): Change the semantics: instead of arriving to
4690 this label when value and location have been pushed, but yystate
4691 is to be pushed on the state stack, now the three of them must
4692 have been pushed before. yystate still must be the new state.
4693 This allows to use yypush_ everywhere instead of individual
4694 handling of the stacks.
4695
4696 2008-11-03 Akim Demaille <demaille@gostai.com>
4697
4698 Prefer references to pointers.
4699 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
4700 definition to use references instead of pointers.
4701 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
4702 Take the value and location as references.
4703 Adjust callers.
4704
4705 2008-11-03 Akim Demaille <demaille@gostai.com>
4706
4707 stack::size instead of stack::height.
4708 * data/lalr1.cc (stack::height): Rename as...
4709 (stack::size): this.
4710 Fix the output type.
4711 Comment changes.

4713 2008-11-03 Akim Demaille <demaille@gostai.com>
4714
4715 Use variants to support objects as semantic values.
4716 This patch was inspired by work by Michiel De Wilde. But he used
4717 Boost variants which (i) requires Boost on the user side, (ii) is
4718 slow, and (iii) has useless overhead (the parser knows the type of
4719 the semantic value there is no reason to duplicate this
4720 information as Boost.Variants do).
4721
4722 This implementation reserves a buffer large enough to store the
4723 largest objects. yy::variant implements this buffer. It was
4724 implemented with Quentin Hocquet.
4725
4726 * src/output.c (type_names_output): New.
4727 (output_skeleton): Invoke it.
4728 * data/c++.m4 (b4_variant_if): New.
4729 (b4_symbol_value): If needed, provide a definition for variants.
4730 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
4731 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
4732 (b4_char_sizeof, yy::variant): New.
4733 (parser::parse): If variants are requested, define
4734 parser::union_type, parser::variant, change the definition of
4735 semantic_type, construct $$ before running the user action instead
4736 of performing a default $$ = $1.
4737 * examples/variant.yy: New.
4738 Based on an example by Michiel De Wilde.
4739
4740 2008-11-03 Akim Demaille <demaille@gostai.com>
4741
4742 Parameterize the extraction of semantic values.
4743 To make future changes easier, no longer rely on ".TYPE" being the
4744 way to get a semantic value.
4745
4746 * data/c.m4 (b4_symbol_value): New.
4747 Use it.
4748 * data/c++.m4, data/yacc.c: Use it.
4749 * data/glr.c: Use b4_symbol_value.
4750 (b4_rhs_data): New.
4751 Use it.
4752
4753 2008-11-03 Akim Demaille <demaille@gostai.com>
4754
4755 Prepare easier M4 changes.
4756 * data/lalr1.cc: Use escaped [] instead of literals to prepare
4757 future changes.

4856
4857 Always put auxiliary code files in the same dir as other output files.
4858 * src/files.c (compute_file_name_parts): When the user specifies
4859 --output but not --file-prefix, extract the directory prefix from the
4860 file prefix not from the grammar file name. This affects the location
4861 of files like location.hh generated by the C++ skeleton. The includes
4862 in the other output files require this fix.

5096 2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
5097
5098 Fix dependence on computed configure variables.
5099 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
5100 $(top_srcdir)/configure.ac so that changes to computed variables, such

5124 (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
5125 .prev-version, and .version.
5126 * NEWS (2.3b+): Rename to...
5127 (?.?): ... this because we're dropping the "+" version naming scheme,
5128 but, in general, we still can't be sure of our next release name.
5129 * bootstrap: Add a quick hack to remove from .gitignore the
5130 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
5131 entry. This should really be fixed in gnulib instead.
5132 * bootstrap.conf (gnulib_modules): Add gnumakefile.
5133 * configure.ac (AC_INIT): Set version name by invoking

5165 * bootstrap (insert_sorted_if_absent): Replace all uses with...

5167 .gitignore entries before passing them to insert_sorted_if_absent.
5168 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
5169 .cvsignore files are maintained even though Bison developers run
5170 bootstrap while using Git.
5171 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
5172 unneeded by Bison.
5173 (gnulib): Add.
5174 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
5175 unneeded. Reported by Eric Blake.
5176 * lib/.gitignore (/*~): Add.
5177 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
5178 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
5179 Blake.
5180 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.

5189 (/setenv.m4): Add.
5190 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
5191 the first argument because it may become position-dependent, and unset
5192 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
5193 Add comments explaining these issues in more detail.
5194
5195 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

5256
5257 Revert prior patch, by working around autoconf regression.
5258 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
5259 ("Output file name: ("): Uncomment test.
5260 ("Output file name: )"): Likewise.
5261 Based on an idea from Noah Misch.
5262
5263 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5264
5265 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
5266 2.61. Reported by Juan Manuel Guerrero at
5267 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
5268 * tests/output.at ("Output file name: ("): Comment out test case for
5269 now.
5270 ("Output file name: )"): Likewise.
5271
5272 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

5275 succeeds.
5276
5277 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5278
5279 Update to the current gnulib CVS repository, and fix trigraph handling
5280 in Bison.
5281 * bootstrap: Update gnulib CVS repository URL.
5282 (symlink_to_dir): Encapsulate the code that guarantees the destination
5283 directory exists into...
5284 (check_dst_dir): ... this new function, and...
5285 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
5286 fail when copying files into lib/uniwidth/.
5287 * src/output.c (prepare_symbols): When writing yytname muscles, where
5288 symbol names will be encoded in C-string literals, tell quotearg to
5289 escape trigraphs. This used to be the default in gnulib.
5290 * tests/regression.at (Token definitions): Because of the change in
5291 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
5292 escapes trigraphs in symbol names. Thus, yytname no longer has
5293 trigraphs unnecessarily doubly escaped. Update test case output.
5294 Extend test case to be sure Bison's own error messages will no longer
5295 have trigraphs in symbol names unnecessarily escaped once.
5296

5309 * NEWS (2.3a+): Mention that -g now takes an argument.
5310 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
5311 consistency. Update the -g and -x entries now that they take
5312 arguments. Use brackets to indicate optional arguments.
5313 * src/getargs.c (usage): Explain the relationship between arguments of
5314 long and short options more completely. Document --defines and -d
5315 separately since the former takes an argument but, for POSIX Yacc, the
5316 latter does not.
5317 (short_options): Let -W take an optional argument like --warnings.
5318 (getargs): Sort cases.
5319

5330
5331 * src/getargs.c (short_options): Split and sort for readability.
5332 -g and -x take optional arguments, just like their long options.
5333 * build-aux/cross-options.pl: Use /x to make the regexp easier to
5334 understand.
5335 Fix the handling of $opt which resulted in all the argument to be
5336 considered as optional.
5337
5338 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

5837 * data/xslt/xml2dot.xsl (xsl:template match="automaton/state"): After
5838 2007-10-11 change, the child elements here are items not rules.
5839 (xsl:template match="item"): New.
5840 (xsl:template match="rule"): Update for new reduced itemset.
5841 (xsl:template match="point"): Remove.
5842 (xsl:template match="empty"): For consistency with --graph, don't
5843 output "/* empty */".
5844 * data/xslt/xml2text.xsl (xsl:template match="terminal"): When invoking
5845 line-wrap, don't pass a negative value as first-line-length since this
5846 won't work with the following changes.
5847 (xsl:template name="line-wrap"): Simplify slightly.
5848 (xsl:template name="ws-search"): Eliminate recursion.
5849 * src/print_graph.c (print_core): Don't print a reduction's lookahead
5850 set next to an item whose dot is not at the end of the RHS even if it
5851 happens to be associated with the same rule.
5852
5853 2007-10-19 Joel E. Denny <jdenny@ces.clemson.edu>
5854

5860 Extend to test it, and fix a typo.
5861
5862 2007-10-19 Joel E. Denny <jdenny@ces.clemson.edu>
5863
5864 * NEWS (2.3a+): Add entry for recent .output file lookahead set fix.
5865 * doc/bison.texinfo (Understanding): Remove a bogus lookahead set in
5866 the example .output text.
5867 * tests/regression.at (Extra lookahead sets in report): Improve wording
5868 of comments.
5869
5870 2007-10-17 Wojciech Polak <polak@gnu.org>
5871
5872 * src/print-xml.c (print_grammar): Renamed
5873 <terminal> and <nonterminal> attributes:
5874 "type" to "number" and "symbol" to "name".
5875 * data/xslt/xml2text.xsl (xsl:template match="terminal"):
5876 Use new attribute names.
5877 (xsl:template match="nonterminal"): Likewise.
5878 * data/xslt/xml2xhtml.xsl: Likewise.
5879
5880 2007-10-17 Joel E. Denny <jdenny@ces.clemson.edu>
5881
5882 * doc/bison.texinfo (Bison Options): Add entry for --print-datadir.
5883 (Option Cross Key): Likewise.
5884
5885 * src/print-xml.c (print_core): Don't print a reduction's lookahead set
5886 next to an item whose dot is not at the end of the RHS even if it
5887 happens to be associated with the same rule.
5888 * src/print.c (print_core): Likewise.
5889 * tests/conflicts.at (Unresolved SR Conflicts): Update output.
5890 (Resolved SR Conflicts): Update output.

5892
5893 2007-10-11 Wojciech Polak <polak@gnu.org>
5894
5895 * src/print-xml.c (print_core): Remove item set
5896 redundancy.
5897 * data/xslt/bison.xsl (bison:ruleNumber): New key.

5901 * data/xslt/xml2text.xsl (xsl:template match="item"): New.
5902 (xsl:template match="rule"): Support new reduced itemset.
5903 (xsl:template match="point"): Remove.

5909
5910 2007-10-09 Joel E. Denny <jdenny@ces.clemson.edu>
5911
5912 Make xml2dot.xsl and --graph produce the same output.
5913 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
5914 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
5915 escaped later.
5916 (xsl:template name="output-node"): Use the new escape template instead
5917 of the string-replace template directly.
5918 (xsl:template name="output-edge"): Likewise.

5920 addition to quotation marks.
5921 * src/graphviz.c (start_graph, output_node, output_edge): Add
5922 whitespace to output for legibility.
5923
5924 Make xml2text.xsl and --report produce the same output, and remove the
5925 XML "conflicts" element since a conflict summary is easily extracted
5926 from the automaton.
5927 * data/xslt/bison.xsl: New.
5928 (xsl:template match="state" mode="bison:count-conflicts): New.
5929 * data/xslt/xml2text.xsl: Import bison.xsl.
5930 (xsl:template match="bison-xml-report"): Instead of styling the
5931 "conflicts" element, style the "automaton" element with mode
5932 "conflicts". Unlike the former, the latter lists S/R and R/R
5933 conflicts for a state on the same line.
5934 (xsl:template match="conflicts"): Remove.
5935 (xsl:template match="conflict"): Remove.
5936 (xsl:template match="terminal"): Line-wrap the list of rules in which

5940 (xsl:template match="state" mode="conflicts"): New.
5941 (xsl:template name="line-wrap"): New.
5942 (xsl:template name="ws-search"): New.
5943 * data/xslt/xml2xhtml.xsl: Import bison.xsl.
5944 (xsl:template match="bison-xml-report"): Instead of styling the
5945 "conflicts" element, style the "automaton" element with mode
5946 "conflicts."
5947 (xsl:template match="conflicts"): Remove.
5948 (xsl:template match="conflict"): Remove.
5949 (xsl:template match="automaton" mode="conflicts"): New.
5950 (xsl:template match="state" mode="conflicts): New.
5951 * src/conflicts.c (conflicts_output_xml): Remove.
5952 * src/conflicts.h (conflicts_output_xml): Remove prototype.
5953 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
5954 * src/print.c (print_grammar): Consistently wrap at the 66th column so
5955 the corresponding XSLT is easier. Also, never wrap between a word and
5956 the comma that follows it.
5957
5958 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
5959
5960 Improve C++ namespace support. Discussed starting at
5961 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
5962 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
5963 b4_namespace_close): New macros that interpret the %define variable
5964 "namespace" so its value can contain "::" to indicate nested
5965 namespaces.
5966 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
5967 the above macros.
5968 * data/lalr1.cc (b4_namespace): Likewise.
5969 * data/location.cc (b4_namespace): Likewise.
5970 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
5971 inside a new table in the general %define entry. Document `%define
5972 namespace' there as well. Point the %name-prefix entry to it since it
5973 explains it more completely in the case of C++.
5974 (C++ Bison Interface): Mention `%define namespace' instead of
5975 %name-prefix.
5976 (Table of Symbols): Remove the `%define push_pull' entry. The %define
5977 entry suffices.
5978 * tests/c++.at (Relative namespace references): New test case.
5979 (Absolute namespace references): New test case.
5980 (Syntactically invalid namespace references): New test case.
5981 * tests/input.at (C++ namespace reference errors): New test case.

5988 (b4_percent_define_get_syncline): New.
5989 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
5990 (b4_percent_define_default): Record defining location as line 1 rather
5991 than 0 for the sake of synchronizing #line's, and define
5992 b4_percent_define_syncline(VARIABLE).
5993 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
5994 * src/muscle_tab.c (muscle_syncline_grow): New.
5995 (muscle_code_grow): Use muscle_syncline_grow.
5996 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
5997 define b4_percent_define_syncline(VARIABLE).
5998 (muscle_percent_define_get_loc): New.
5999 (muscle_percent_define_get_syncline): New.
6000 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
6001 remove some unused variables.
6002 (muscle_percent_define_default): Record defining location as line 1
6003 rather than 0 for the sake of synchronizing #line's, and define
6004 b4_percent_define_syncline(VARIABLE).
6005 (muscle_percent_define_check_values): Use
6006 muscle_percent_define_get_loc.
6007 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
6008 (muscle_percent_define_get_syncline): Prototype.

6012 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
6013
6014 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
6015
6016 Fix some error-reporting macro bugs.
6017 * data/bison.m4 (b4_cat): New.
6018 (b4_error, b4_error_at): Use b4_cat to send error directives directly
6019 to stdout so they don't become arguments to other macros. Update
6020 comments and add examples.
6021 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
6022 add examples.
6023 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
6024 after printing the error directive so that M4 doesn't report subsequent
6025 problems that are induced by this problem.
6026 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
6027 instead of just in them. Recognize @\n in both places. Both expand to
6028 the empty string. Needed by b4_cat.
6029 * tests/skeletons.at (Complaining during macro argument expansion):
6030 New test case.
6031 (Fatal errors make M4 exit immediately): New test case.
6032

6038 (long_options): Add entry for it.
6039 (getargs): Add case for it calling compute_pkgdatadir.
6040 * src/output.c (output_skeleton): Encapsulate data directory
6041 computation from here...
6042 (prepare): ... and from here...
6043 (compute_pkgdatadir): ... into this new function.
6044 * src/output.h (compute_pkgdatadir): Prototype.
6045
6046 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
6047
6048 * src/print-xml.c (escape_bufs): New static global variable
6049 replacing...

6055
6056 Replace `%push-parser' and `%push-pull-parser' with
6057 `%define push_pull "push"' and `%define push_pull "both"'.
6058 `%define push_pull "pull"' is the default.
6059 * doc/bison.texinfo (Push Decl, Push Parser Function,
6060 Pull Parser Function, Parser Create Function, Parser Delete Function):
6061 Update declarations.
6062 (Decl Summary, Table of Symbols): Replace %push-parser and

6066 definitions...
6067 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
6068 definitions...
6069 * data/push.c: ... to here and compute them from the value of the
6070 %define variable push_pull.
6071 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
6072 parsing requests here...
6073 * data/yacc.c: ... hack this to switch to push.c any time
6074 b4_use_push_pull_flag or the %define variable push_pull is set. This
6075 will go away when we mv push.c yacc.c.
6076 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
6077 push parsing is not supported since unused %define variables are
6078 reported anyway.
6079 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
6080 * src/muscle_tab.h (muscle_percent_define_check_values): Update

6094 (Push Parsing: Unsupported Skeletons): New test case.
6095 * tests/torture.at (Exploding the Stack Size with Alloca): Update
6096 declaration.
6097 (Exploding the Stack Size with Malloc): Update declaration.
6098

6120 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
6121 `char const *' instead of `char *'.
6122 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
6123 local variable `sep'.
6124
6125 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
6126
6127 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
6128 elsewhere.
6129 * src/print-xml.c: Prefer "const" after types; that's more consistent.
6130 (xml_printf): Indent just 1 space for level.
6131 (e_char, xlate_char): Remove.
6132 (xml_escape_string): Rewrite to avoid undefined behavior (used

6204
6205 In impure push mode, don't allow more than one yypstate to be allocated
6206 since multiple impure parsers would corrupt yynerrs.

6208 initialized to 0.
6209 (yypull_parse): If yypstate_new returns 0, don't report it as memory

6286 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
6287
6288 Get rid of broken %no-parser, -n, and --no-parser implementation and
6289 documentation.
6290 * TODO: Don't mention them.
6291 * doc/bison.1: Likewise.
6292 * doc/bison.texinfo (Decl Summary): Likewise.
6293 (Bison Options): Likewise.
6294 (Option Cross Key): Likewise.
6295 * src/getargs.c (no_parser_flag): Remove global variable.
6296 (usage): Don't print description of -n and --no-parser.
6297 (long_options): Remove --no-parser entry here.
6298 (getargs): Remove -n case in the switch here.
6299 * src/getargs.h (no_parser_flag): Remove extern.
6300 * tests/regression.at (Web2c Actions): Remove comment that mentions
6301 --no-parser.
6302
6303 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
6304
6305 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
6306 name user variables starting with `yy'. Just pass NULL instead of a
6307 dummy local &yylval to yypush_parse.
6308 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
6309 starting with `yy'.
6310
6311 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
6312
6313 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
6314 true since it's then always used regardless of whether yyoverflow is
6315 defined. Reported by Christian Burger at
6316 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
6317 * THANKS: Add Christian Burger.
6318
6319 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6320 node names: say "Decl Summary" not "Bison Declaration Summary".
6321
6322 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
6323
6324 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
6325 determine whether this function has already complained about an invalid
6326 value for a %define boolean variable, don't check whether Bison has
6327 ever examined the value. As written, the check was a tautology.
6328 Instead, record and check for this complaint using a separate muscle.
6329
6330 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
6331
6332 Fix push parsing memory leak reported by Brandon Lucia at
6333 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
6334 * THANKS: Add Brandon Lucia.
6335 * data/push.c (yypstate_delete): Free the stack if it was reallocated
6336 but the parse never completed and thus freed it.
6337 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
6338 * tests/testsuite.at: Include push.at.
6339 * test/push.at: New.
6340 (Push Parsing: Memory Leak for Early Deletion): New test case.
6341
6342 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
6343
6344 Improve handling of multiple S/R conflicts in the same state and of S/R
6345 conflicts involving multiple reductions.
6346 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
6347 set for a state here or Bison will abort if it is reassigned on a
6348 later conflicted reduction in the same state.
6349 Similarly, don't finalize and assign the solved conflicts report here
6350 or it will be lost if it is reassigned on a later conflicted reduction
6351 in the same state.
6352 (set_conflicts): Instead, assign them both here after all S/R conflicts
6353 in the state have been fully examined.
6354 * src/print.c (shift_set): Rename to...
6355 (no_reduce_set): ... this.
6356 (print_reductions): Update for rename, and add %nonassoc error action
6357 tokens to no_reduce_set so that, when printing the first remaining
6358 reduction on an error action token, the reduction is enclosed in
6359 brackets.
6360 (print_results): Update for rename.
6361 * tests/conflicts.at (Solved conflicts report for multiple reductions
6362 in a state): New test case.
6363 (%nonassoc error actions for multiple reductions in a state): New test
6364 case.
6365
6366 * src/main.c (main): Don't depend on C99 features.
6367
6368 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
6369
6370 * build-aux/.cvsignore: Add compile.
6371 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
6372 uniwidth.
6373
6374 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
6375
6376 * bootstrap (slurp): Create target directories that don't exist.
6377 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
6378
6379 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6380
6381 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
6382 than item number.
6383 * closure.c (closure): Likewise.
6384 * state.h (reductions): Comment sorting of rules.
6385 (state): Comment sorting of items.
6386
6387 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
6388
6389 Fix C++ test cases after recent Gnulib changes. Discussed starting at
6390 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
6391 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
6392 definition in order to avoid Gnulib headers since we don't use config.h
6393 here.
6394 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
6395 rather than AT_DATA so that config.h is included.
6396
6397 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
6398
6399 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
6400 instead of fprintf. Guard these functions with #if YYDEBUG instead of
6401 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
6402 and so that YYFPRINTF is guaranteed to be defined here.
6403
6404 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6405
6406 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
6407 with...
6408 (muscle_percent_define_check_values): ... this more helpful function.
6409 Again, it's not used yet, but it will be.
6410 * src/muscle_tab.h: Likewise.
6411
6412 Improve some comments in parser table construction.
6413 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
6414 (generate_states): Don't mention ruleset, which is internal to closure.
6415 * src/closure.c (closure): Explain sorting of core and itemset, which
6416 is required for this function to behave correctly.
6417 * src/closure.h (closure): Mention sorting.
6418
6419 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
6420
6421 * src/lalr.c (state_lookahead_tokens_count): For code readability,
6422 move the check for disabled transitions to an aver since conflict
6423 resolution hasn't happened yet.
6424
6425 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
6426 labels a state as inconsistent just because it has error transitions.
6427 The original form of this check appeared in revision 1.1 of lalr.c,
6428 which was committed on 1991-12-21. Now (at least), changing the
6429 consistency label on such a state appears to have no useful effect in
6430 any of the places it is examined, which I enumerate below. The key
6431 point to understanding each item in this enumeration is that a state
6432 with an error transition is labelled consistent in the first place only
6433 if it has no rules, so the check cannot matter for states that have
6434 rules. (1) Labelling a state as inconsistent will cause set_conflicts
6435 to try to identify its conflicts, and a state must have *rules* to have
6436 conflicts. (2) Labelling a state as inconsistent will affect how
6437 action_row sets the default *rule* for the state. (3) Labelling a
6438 state as inconsistent will cause build_relations to add lookback edges
6439 to *rules* in that state.
6440 * src/state.h (struct state): Word the comment for member consistent
6441 more carefully.
6442
6443 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
6444
6445 Don't depend on C99 features.
6446 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
6447 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
6448 * src/reader.c (check_and_convert_grammar): Fix for-loop.
6449 * src/state.c (state_mark_reachable_states): Fix for-loop.
6450 (state_remove_unreachable_states): Fix for-loop.
6451
6452 Don't widen struct state with member reachable just to temporarily
6453 record reachability. Instead, use a local bitset.
6454 * src/state.h (struct state): Remove member.
6455 * src/state.c (state_new): Don't initialize it.
6456 (state_mark_reachable_states): Rename to...
6457 (state_record_reachable_states): ... this, and use bitset.
6458 (state_remove_unreachable_states): Use bitset.
6459
6460 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
6461
6462 * src/Makefile.am (yacc): Quote target action commands properly so
6463 that the yacc script isn't corrupt. Reported by Hans Aberg at
6464 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
6465
6466 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
6467 the case of pure parsers. Reported by Frans Englich at
6468 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
6469 * THANKS: Add Frans Englich.
6470
6471 * NEWS (2.3a+): In the %code entry, reference section `Bison
6472 Declaration Summary' from the manual now since the %code summary has
6473 moved there.
6474 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
6475 in the rules section must be terminated by semicolons.
6476
6477 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
6478
6479 Extend the front-end API for %define variables to more completely
6480 mirror the back-end. This will be useful in the future.
6481 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
6482 Update comments to mention the new front-end counterparts of these
6483 macros.
6484 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
6485 for muscle_string_decode and muscle_location_decode.
6486 (muscle_string_decode): New static function.
6487 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
6488 (muscle_percent_define_get, muscle_percent_define_ifdef): New
6489 functions.
6490 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
6491 muscle_percent_define_get to mimic the b4_percent_define_flag_if
6492 implementation more closely.
6493 (muscle_percent_define_invalid_value): New function.
6494 * src/muscle_tab.h (muscle_percent_define_get,
6495 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
6496 Prototype.
6497
6498 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
6499
6500 * NEWS (2.3a+): Mention yesterday's state-removal change.
6501 (2.3a): Remove the %language entry, which was added after 2.3a.
6502 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
6503 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
6504 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
6505 tests/existing.at: Update copyright date.
6506
6507 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
6508
6509 If conflict resolution makes states unreachable, remove those states,
6510 report rules that are then unused, and don't report conflicts in those
6511 states.
6512 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
6513 New global function.
6514 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global
6515 function.
6516 * src/main.c (main): After conflict resolution, remove the unreachable
6517 states and update all data structures that reference states by number.
6518 * src/state.c (state_new): Initialize each state's reachable member to
6519 false.
6520 (state_mark_reachable_states): New static function.
6521 (state_remove_unreachable_states): New global function.
6522 * src/state.h (struct state): Add member bool reachable.
6523 (state_remove_unreachable_states): Prototype.
6524 * tests/conflicts.at (Unreachable States After Conflict Resolution):
6525 New test case.
6526 * tests/existing.at (GNU pic Grammar): Update test case output now that
6527 an unused rule is discovered.
6528
6529 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
6530
6531 Minor code cleanup in parser table construction.
6532 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
6533 (new_itemsets, save_reductions): Update for rename to nitemset.
6534 * src/closure.c (nritemset): Rename to...
6535 (nitemset): ... this since the "r" appears to meaningless and isn't
6536 used in the comments.
6537 (closure): Update for rename.
6538 * src/closure.h (nritemset): Update extern to...
6539 (nitemset): ... this.

6544
6545 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
6546
6547 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
6548 still sticks to ASCII. Sorry!
6549
6550 * README-hacking: New file, taken mostly from coreutils, with changes
6551 for Bison. Contains much of the contents of:
6552 * README-cvs: Remove.
6553 * bootstrap: Sync from gnulib.
6554 * build-aux/.cvsignore: Remove *.t, mkinstalldirs.

6580 (YYStack, yyaction, yyparse): Rename b4_union_name to b4_yystype.
6581
6582 * doc/bison.texinfo (Java Bison Interface): Mention "%define
6583 abstract". Rename "%define union_name" to "%define stype".
6584 Rename method names according to previous patch.
6585 (Java Scanner Interface): Describe "%code lexer" instead of

6598
6599 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6600
6601 DJGPP spefic issue. Inhibit the use of disallowed characters for
6602 file name genertion on Win98, WinXP, etc. These are |<>":?*\
6603 and concern testsuite case 46.
6604 * Makefile.am: djgpp/testsuite.sed added to EXTRA_DIST
6605 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
6606 * djgpp/config.bat: Inhibit the use of disallowed characters.
6607
6608 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6609
6610 Miscellaneous %define and %code cleanup.
6611 * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
6612 values are interpreted.
6613 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
6614 documentation a little more.
6615 * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
6616 muscle_percent_define_insert, muscle_percent_code_grow): New
6617 functions/macros.
6618 * src/muscle_tab.h (muscle_percent_define_insert,
6619 muscle_percent_code_grow): Prototype.
6620 * src/parse-gram.y (prologue_declaration): Use
6621 muscle_percent_define_insert and muscle_percent_code_grow when parsing
6622 %define and %code directives.
6623
6624 Make it easy to share %define boolean variables between the front-end
6625 and back-end. Though not used yet, this will be useful in the future.
6626 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
6627 Bison uses of names rather than just skeleton uses of names.
6628 (b4_percent_define_get, b4_percent_define_ifdef): Rename

6635 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
6636 muscle_percent_define_default): New functions mimicking
6637 b4_percent_define_flag_if and b4_percent_define_default.
6638
6639 For %define variables, report locations for invalid values and
6640 redefinitions.
6641 * data/bison.m4 (b4_percent_define_flag_if): Read
6642 b4_percent_define_loc(VARIABLE) to report the location of an invalid
6643 value for VARIABLE.
6644 (b4_percent_define_default): Save a special location in
6645 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
6646 must later be reported as invalid.
6647 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
6648 functions.
6649 (muscle_percent_define_insert): Record the location of VARIABLE in
6650 muscle percent_define_loc(VARIABLE), and use it to report the previous
6651 location for a redefinition.
6652 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
6653 (muscle_percent_define_default): Update like b4_percent_define_default.
6654 (muscle_grow_user_name_list): Rename to...
6655 (muscle_user_name_list_grow): ... this for consistency and use
6656 muscle_location_grow.
6657 * src/muscle_tab.h (muscle_location_grow): Prototype.
6658 * tests/input.at (%define errors): Update expected output.
6659 * tests/skeletons.at (%define boolean variables: invalid skeleton
6660 defaults): New test case.
6661
6662 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
6663
6664 * src/print.c (lookahead_set, state_default_rule): Remove.
6665 (print_reductions): Replace state_default_rule invocation with
6666 equivalent use of yydefact, which was computed in token_actions in
6667 tables.c.
6668 (print_results): Don't allocate lookahead_set.
6669
6670 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
6671
6672 * data/lalr1.java: Prefix all private members with yy.
6673
6674 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
6675
6676 Use YYFPRINTF instead of fprintf where appropriate. Reported by
6677 Sebastien Fricker at
6678 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
6679 * THANKS: Add Sebastien Fricker.
6680 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
6681 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
6682 accept a variable number of arguments.
6683
6684 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
6685
6686 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
6687
6688 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6689
6690 * djgpp/config.bat: Adjustments concerning the use of autoconf 2.61.
6691 * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
6692 * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
6693
6694 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
6695
6696 Undo my 2007-02-07 change, switching back to the c-strcase module
6697 introduced in the 2007-02-03 change. Bruno Haible reported that
6698 the 2007-02-07 change would be dangerous in Turkish if we add a
6699 language whose name contains "i", since "i" is not lowercase "I"
6700 in Turkish.
6701 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
6702 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
6703 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
6704 * m4/.cvsignore: Remove strcase.m4.
6705 * src/getargs.c: Revert 2007-02-07 change, as follows.
6706 Include c-strcase.h.
6707 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
6708
6709 2007-02-11 Bruno Haible <bruno@clisp.org>
6710
6711 Enable the Java related testsuite tests when the only Java compiler
6712 found is a gcj < 4.3. Discussed at
6713 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
6714 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
6715
6716 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
6717
6718 * data/Makefile.am: Update copyright date.
6719 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
6720 yypstate_new returns NULL.
6721 (yypstate_new): Return NULL if malloc does.
6722 * src/reader.c (packgram): Move translation of rule actions from the
6723 beginning of packgram to...
6724 (check_and_convert_grammar): ... here right before packgram is invoked
6725 so it's easier to write more complete comments, and remove redundant
6726 code.
6727
6728 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
6729
6730 As in semantic actions, make @$ in %initial-action, %destructor, and
6731 %printer imply %locations.
6732 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
6733 scanning @$.
6734 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
6735 (@$ in %initial-action implies %locations,
6736 @$ in %destructor implies %locations,
6737 @$ in %printer implies %locations): ... these new test cases.
6738
6739 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
6740
6741 Undo most of the 2007-02-03 change, switching to the strcase module
6742 now that gnulib strcase has been fixed.
6743 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
6744 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
6745 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
6746 * m4/.cvsignore: Add strcase.m4.
6747 * src/getargs.c: Revert 2007-02-03 change, as follows.
6748 Don't include c-strcase.h.
6749 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
6750 strcasecmp has "unspecified behavior" outside the POSIX locale,
6751 but it works fine in practice if at least one argument is ASCII,
6752 as is the case in Bison.
6753
6754 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
6755
6756 * tests/java.at: Skip tests if only one of javac/java is present.
6757 Reported by Joel E. Denny.
6758 * tests/atlocal.in: Adjust copyright years.
6759
6760 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
6761
6762 * data/lalr1.java (Stack): Work around old verifiers that disallow
6763 access to the private fields of an inner class, from the outer class.
6764 We can make Stack's fields public because user code doesn't have access
6765 to the instance of Stack used by parse(). Reported by Paul Eggert.
6766
6767 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
6768
6769 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
6770 the right spot for these files?
6771 * bootstrap.conf (gnulib_modules): Add c-strcase.
6772 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
6773 c-strncasecmp.c.
6774 * src/getargs.c: Include c-strcase.h.
6775 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
6776 to avoid unspecified behavior.
6777
6778 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
6779
6780 * doc/bison.texinfo (Decl Summary): Correct typo.
6781
6782 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
6783
6784 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
6785 Complain if the value does not match empty, "true" or "false".
6786 * data/c++.m4: Adjust default definitions of %define variables.
6787 * data/java.m4: Adjust default definitions of %define variables.
6788 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
6789 to above behavior.
6790 * tests/input.at (Boolean %define variables): Test new behavior.
6791
6792 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
6793
6794 * NEWS: Mention java.
6795 * TODO: Remove things that are done.
6796 * bootstrap.conf: Add javacomp-script and javaexec-script.
6797 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
6798
6799 * data/Makefile.am: Add new files.
6800 * data/java-skel.m4: New.
6801 * data/java.m4: New.
6802 * data/lalr1.java: New.
6803
6804 * doc/bison.texinfo: Put "A Complete C++ Example" under
6805 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
6806 under Other Languages.
6807
6808 * src/getargs.c (valid_languages): Add Java.
6809 * src/getargs.h (struct bison_language): Update size of string fields.
6810
6811 * tests/Makefile.am: Add java.at.
6812 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
6813 * tests/java.at: New.
6814 * tests/testsuite.at: Include it.
6815
6816 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
6817
6818 Clean up.
6819 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
6820 at_directive_argv arguments so these no longer have to be global
6821 variables. Also, update the implementation for the following changes.
6822 (fail_for_at_directive_too_many_args,
6823 fail_for_at_directive_too_few_args): Add at_directive_name argument.
6824 (at_directive_name): Remove as at_directive_argv[0] will be used for
6825 this now.
6826 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
6827 for the directive name.
6828 (at_directive_argc, at_directive_argv): Make these local within
6829 skel_lex instead of global.
6830 (INITIAL): Update directive start action for above changes.
6831 (SC_AT_DIRECTIVE_ARG): Rename to...
6832 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
6833 (SC_AT_DIRECTIVE_SKIP_WS): Update.
6834 (scan_skel): Move yylex_destroy to...
6835 (skel_scanner_free): ... here.
6836 * tests/skeletons.at (installed skeleton file name): Rename to...
6837 (installed skeleton file names): ... this.
6838
6839 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
6840
6841 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6842 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
6843 Summary" not "Directives".
6844 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
6845 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
6846 since the former is now the more complete one.
6847 (Prologue Alternatives): Likewise and do the same for %defines.
6848 (Table of Symbols): Add summary of %code, add summary of %define, and
6849 move full %code documentation to...
6850 (Decl Summary): ... here for consistency with other entries in these
6851 sections.
6852 Move %define entry in order to keep this list alphabetized.
6853 Reword %define entry a little to put less emphasis on the skeleton
6854 concept, which most users shouldn't have to think about.
6855
6856 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
6857
6858 Adjust to recent gnulib changes.
6859 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
6860 Add string.h, string_.h, unistd_.h, wchar_.h.
6861 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
6862 * src/system.h: Don't include <stpcpy.h>; this is now done by
6863 <string.h>.
6864
6865 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
6866
6867 Simplify implementation of unqualified %code, implement macros for
6868 uniform treatment of boolean %define flags. Document %define.
6869 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
6870 b4_percent_code_ifdef): New.
6871 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
6872 * data/c++.m4: Define default value for global_tokens_and_yystype.
6873 * data/glr.cc: Likewise.
6874 * data/location.cc: Use b4_percent_define_flag_if.
6875
6876 * doc/bison.texinfo (Decl Summary): Document %define.
6877
6878 * src/parse-gram.y (Unqualified %code): Change muscle name to
6879 b4_percent_code().
6880 (content.opt): Default to empty.
6881
6882 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
6883
6884 Implement support for relative and absolute skeleton file names.
6885 Discussed starting at
6886 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
6887 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
6888 (Bison Options): Document in --skeleton entry.
6889 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
6890 full_skeleton can't necessarily hold all of pkgdatadir.
6891 If the specified skeleton file name contains a `/', don't prepend
6892 pkgdatadir.
6893 * src/parse-gram.y (prologue_declaration): If the specified skeleton
6894 file name contains a `/', prepend the grammar file directory.
6895 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
6896 * skeletons.at: New file.
6897 (relative skeleton file names): New test case.
6898 (installed skeleton file names): New test case.
6899 * tests/testsuite.at: Include skeletons.at.
6900
6901 * bootstrap: Update copyright to 2007.
6902
6903 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
6904
6905 * bootstrap: Remove occurrences of .#bootmp from the files.
6906
6907 2007-01-17 Akim Demaille <akim@epita.fr>
6908
6909 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
6910 nonterminals.
6911 Use per-type %printer.
6912
6913 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
6914
6915 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,
6916 data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,

6922
6923 2007-01-16 Akim Demaille <akim@epita.fr>
6924
6925 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
6926 error code.
6927 (Calc++ Scanner): Exit with failure if we can't open the input
6928 file.
6929 Accept "-" standing for stdin.
6930 (Calc++ Top Level): Print the result only if the parsing was
6931 successful.
6932
6933 2007-01-16 Akim Demaille <akim@epita.fr>
6934
6935 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
6936
6937 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
6938 and Joel E. Denny <jdenny@ces.clemson.edu>
6939
6940 Clean up %define and %code implementation in M4 some. Most
6941 importantly, rename all related macros to be in the b4_percent_define
6942 and b4_percent_code namespaces. Also, complete support for `.' in
6943 %define variable names and %code qualifiers.
6944 * data/bison.m4 (b4_check_user_names): Check for special
6945 "SKELETON-NAMESPACE(name)" macros instead of using two nested
6946 m4_foreach loops.
6947 (b4_get_percent_define, b4_get_percent_code): Rename to...
6948 (b4_percent_define_get, b4_percent_code_get): ... these.
6949 Extend documentation with examples.
6950 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
6951 b4_percent_define_skeleton_variables and
6952 b4_percent_code_skeleton_qualifiers.
6953 Expect any value for the %define variable `foo' to be stored in the
6954 macro named `b4_percent_define(foo)'; expect any %code blocks for the
6955 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
6956 expect any unqualified %code blocks to be stored in a macro named
6957 `b4_percent_code_unqualified'.
6958 Use m4_indir so that %define variable names and %code qualifiers can
6959 contain `.', which is allowed by the grammar parser.
6960 (b4_percent_define_default): New macro to set a default value for a
6961 %define variable.
6962 (m4_wrap): Update wrapped code, and fix some underquoting.
6963 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
6964 Expect grammar uses of %define variables and %code qualifiers to be
6965 defined in b4_percent_define_user_variables and
6966 b4_percent_code_user_qualifiers.
6967 * data/c++.m4: Use b4_percent_define_default rather than
6968 m4_define_default. Fix some underquoting. Skeleton usage of %define
6969 variable define_location_comparison now implies skeleton usage of
6970 %define variable filename_type.
6971 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
6972 data/push.c, data/yacc.c: Update macro names.
6973 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
6974 muscle names.
6975
6976 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6977
6978 DJGPP specific issues.
6979
6980 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
6981 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
6982
6983 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6984
6985 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
6986 run parsers in all tests so that Valgrind is invoked during
6987 maintainer-check-valgrind.
6988 (Duplicate representation of merged trees): Free all semantic values.
6989 (Duplicated user destructor for lookahead): Likewise.
6990
6991 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6992
6993 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
6994 command-line prefix.
6995 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
6996 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
6997 miss Valgrind messages.
6998 (Exploding the Stack Size with Malloc): Likewise.
6999
7000 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7001
7002 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
7003 locals. Reported by Juan Manuel Guerrero at
7004 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
7005 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
7006 Fix some indentation also.
7007 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
7008 explaining this issue.
7009
7010 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
7011 and Joel E. Denny <jdenny@ces.clemson.edu>
7012
7013 Simplify union and prologue handling, and escape union and lex/parse
7014 params with digraphs.
7015 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
7016 values to the empty string since these are no longer guaranteed
7017 initialized by the front-end.
7018 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
7019 braces around b4_user_stype since this is no longer done by the
7020 front-end.
7021 * src/files.c, src/files.h (pre_prologue_obstack,
7022 post_prologue_obstack): Remove.
7023 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
7024 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
7025 with digraphs. This fixes lex params and parse params.
7026 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
7027 * src/output.c (prepare): Remove muscle insertion of the prologues.
7028 (output): Remove freeing of pre_prologue_obstack and
7029 post_prologue_obstack.
7030 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
7031 than prologue_augment for prologue parsing so you don't need prologue
7032 obstacks.
7033 (grammar_declaration): For %union RHS, use `braceless' instead of
7034 "{...}" so that braces are already stripped and code is escaped with
7035 digraphs.
7036 * src/reader.c (prologue_augment): Remove.
7037 (reader): Remove initialization of pre_prologue_obstack and
7038 post_prologue_obstack.
7039 * src/reader.h (prologue_augment): Remove.
7040
7041 * data/c.m4: Remove stray parenthesis.

7045 Remove quotes from variables names in %define directives and from
7046 qualifiers in %code directives, and restrict the characters that are
7047 allowed in them to M4-friendly ones. For %define, continue to support
7048 the quoted form as a deprecated feature. Discussed starting at
7049 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
7050 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
7051 %code.
7052 * doc/bison.texinfo (Prologue Alternatives): Update.
7053 (Decl Summary): In %defines entry, update mention of `%code requires'
7054 and `%code provides'.
7055 (C++ Location Values): Update %define uses.
7056 (Calc++ Parser Interface): Likewise.
7057 (Calc++ Parser): Likewise, and update `%code requires' uses.
7058 (Table of Symbols): Update %code documentation.
7059 * src/parse-gram.y (prologue_declaration): For %define variables, use
7060 `variable' instead of `STRING'.
7061 (grammar_declaration): For %code qualifiers, use `ID' instead of
7062 `STRING'.
7063 (variable): New nonterminal that takes an `ID' or a `STRING'.
7064 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
7065 and %define uses.
7066 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
7067 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
7068 (%define errors): Update %define uses.
7069
7070 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7071
7072 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
7073 instead of muscle_insert for %define values so that M4-special
7074 characters are replaced with digraphs.
7075 * tests/input.at (%define errors): Extend to check weird values.
7076
7077 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7078
7079 Instead of having skeletons declare all valid %define variables and
7080 %code qualifiers, provide macros that retrieve the associated values
7081 and build these lists automatically. Thus Bison will now warn when a
7082 variable or qualifier is not used by the skeleton in the current
7083 invocation regardless of whether it might sometimes be used by that
7084 skeleton in other invocations. Also, move all %define value macros to
7085 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
7086 form, which is replaced by %code.
7087 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
7088 (b4_check_user_names): ... this, and change the series of valid name
7089 arguments to a single list argument for names used in the skeleton
7090 similar to the existing list argument for names used in the grammar.
7091 Warn instead of complaining.
7092 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
7093 values and %code code, to format %code code properly, and to build
7094 lists of all %define variables and %code qualifiers used in the
7095 skeleton: b4_skeleton_percent_define_variables and
7096 b4_skeleton_percent_code_qualifiers.
7097 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
7098 Remove, and...
7099 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
7100 the skeleton names lists can finish building first. In place of
7101 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
7102 expect the lists b4_user_percent_define_variables and
7103 b4_user_percent_code_qualifiers.
7104 * data/c++.m4: Where setting default values for b4_parser_class_name,
7105 b4_location_type, b4_filename_type, b4_namespace, and
7106 b4_define_location_comparison, update their names to the
7107 b4_percent_define_ namespace.
7108 * data/glr.c: Don't use b4_check_percent_define_variables and
7109 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7110 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
7111 (b4_parser_class_name, b4_namespace): Define these using
7112 b4_get_percent_define for parser_class_name and namespace.
7113 * data/location.cc: Use b4_get_percent_define.
7114 * data/push.c: Don't use b4_check_percent_define_variables and
7115 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7116 * data/yacc.c: Likewise, and don't call m4_exit in
7117 b4_use_push_for_pull_if or m4_wrap code will never execute.
7118 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
7119 Rename to...
7120 (muscle_grow_user_name_list): ... this for consistency with the
7121 terminology used in bison.m4.
7122 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
7123 %define variable names, and rename muscle used_percent_define_variables
7124 to user_percent_define_variables.
7125 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
7126 user_percent_code_qualifiers.
7127 (content): Remove.
7128 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
7129 {CODE} form is no longer accepted.
7130 * tests/input.at (Reject bad %code qualifiers): Rename to...
7131 (Reject unused %code qualifiers): ... this, and update test output.
7132 (%define error): Update test output.
7133
7134 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
7135
7136 Check for unrecognized %define variables similar to checking for
7137 unrecognized %code qualifiers. Check for redefined %define variables.
7138 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
7139 generalizes...
7140 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
7141 (b4_check_percent_define_variables): New, also wraps it.
7142 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
7143 variables using b4_check_percent_define_variables.
7144 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
7145 all those exercised in the test suite and all those listed in the
7146 `Default values' section of c++.m4. Are there others?
7147 * data/push.c, data/yacc.c: Declare no valid %define variables.
7148 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
7149 similar to muscle_find, but it works even when the muscle stores a
7150 const value.
7151 (muscle_grow_used_name_list): New function for constructing the used
7152 name list muscles that b4_check_for_unrecognized_names requires.
7153 * src/parse-gram.y (prologue_declaration): Warn if a variable is
7154 %define'd more than once. Define the b4_used_percent_define_variables
7155 muscle with muscle_grow_used_name_list.
7156 (grammar_declaration): Abbreviate %code code with
7157 muscle_grow_used_name_list.
7158 * tests/input.at (%define errors): New.
7159
7160 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7161
7162 Provide warn_at, complain_at, and fatal_at function callbacks to the
7163 skeletons, and use this for %code qualifier complaints.
7164 * data/bison.m4 (b4_error_at): New, invoked by...
7165 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
7166 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
7167 @fatal_at(...@) directives.
7168 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
7169 qualifiers in b4_used_percent_code_qualifiers and to use
7170 b4_complain_at.
7171 * src/location.c, src/location.h (boundary_set_from_string): New global
7172 function.
7173 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
7174 function.
7175 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
7176 to b4_used_percent_code_qualifiers.
7177 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
7178 function.
7179 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
7180 (lineno): Rename to...
7181 (out_lineno): ... this so I don't misunderstand it again.
7182 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
7183 here; these newlines are in the input but not the output file.
7184 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
7185 (at_directive_perform): ... this new static function, and add handling
7186 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
7187 directives.
7188 * tests/input.at (Reject bad %code qualifiers): Update test output with
7189 locations and extend.
7190
7191 * tests/output.at (Output file name: [, Output file name: ]): Remove
7192 bogus comment about these tests failing.
7193
7194 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7195
7196 Clean up b4_check_percent_code_qualifiers a little.
7197 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
7198 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
7199 documentation and add examples.
7200 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
7201 qualifiers here.
7202
7203 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7204
7205 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
7206 unreliable -- especially when they're hidden inside another macro.
7207 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
7208 data/c.m4: Remove m4_divert(-1).
7209 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7210 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
7211 m4_divert_push(0) and m4_divert_pop(0).
7212 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
7213 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
7214 pushed and popped by m4sugar, should be first on the stack.
7215
7216 Provide warn, complain, and fatal function callbacks to the skeletons.
7217 This provides more flexibility than m4_fatal, improves the error
7218 message format, and captures messages for translation. Discussed
7219 starting at
7220 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
7221 * data/bison.m4 (b4_error): New, invoked by...
7222 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
7223 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
7224 directives. Because these M4 macros might be called when the current
7225 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
7226 the previous removal of uses of m4_divert, which caused trouble.
7227 (b4_check_percent_code_qualifiers): Use b4_complain instead of
7228 m4_fatal to report unrecognized %code qualifiers.
7229 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
7230 push parser requests.
7231 * data/glr.c: Use b4_complain instead of m4_fatal to report
7232 non-deterministic push parser requests.
7233 Update @output usage to @output(...@) form.
7234 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
7235 report missing %defines. Update @output usage to @output(...@) form.
7236 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
7237 @output(...@) form.
7238 * src/main.c (main): Invoke skel_scanner_free.
7239 * src/scan-skel.h (skel_scanner_free): Prototype new function.
7240 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
7241 obstack_for_string from flex-scanner.h.
7242 (YY_DECL): Use to declare skel_lex static.
7243 (decode_at_digraphs): Remove; now handled in the new
7244 SC_AT_DIRECTIVE_ARG start condition.
7245 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
7246 functions.
7247 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
7248 at_directive_argv): New static globals.
7249 (INITIAL): Use fail_for_invalid_at.
7250 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
7251 recognize the start of a generalized `@directive(...@)' form and
7252 start...
7253 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
7254 directive args (using the new obstack_for_string), to decode the
7255 contained @ diagraphs, and to perform the directive. It recognizes
7256 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
7257 @output(...@).
7258 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
7259 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
7260 `@,'.
7261 (scan_skel): Initialize obstack_for_string on the first call.
7262 (skel_scanner_free): New function to free obstack_for_string.
7263 * tests/input.at (Reject bad %code qualifiers): Update test output.
7264
7265 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
7266
7267 Consolidate the 4 prologue alternative directives (%code, %requires,
7268 %provides, and %code-top) into a single %code directive with an
7269 optional qualifier field. Discussed at
7270 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
7271 * NEWS (2.3a+): Rewrite the existing entry for the prologue
7272 alternatives.
7273 * doc/bison.texinfo (Prologue Alternatives): Update.
7274 (Decl Summary): Update to %code "requires" and %code "provides".
7275 (Calc++ Parser): Update to %code "requires".
7276 (Table of Symbols): Remove entries for %requires, %provides, and
7277 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
7278 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
7279 are replaced by b4_percent_code_provides and b4_percent_code_requires,
7280 which are skeleton-specific.
7281 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
7282 declare what %code qualifiers it supports and to complain if any other
7283 qualifiers were used in the grammar.
7284 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
7285 and b4_user_code([b4_percent_code_provides]) in place of
7286 b4_user_requires and b4_user_provides.
7287 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
7288 Add b4_user_code([b4_percent_code_top]) and
7289 b4_user_code([b4_percent_code]).
7290 Invoke b4_check_percent_code_qualifiers.
7291 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7292 PERCENT_REQUIRES): Remove.
7293 (grammar_declaration): Remove RHS's for %code-top, %provides, and
7294 %requires. Rewrite the %code RHS as the unqualified form defining the
7295 muscle b4_percent_code. Add another RHS for the qualified %code form,
7296 which defines muscles of the form b4_percent_code_QUALIFIER and the
7297 b4_used_percent_code_qualifiers muscle.
7298 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7299 PERCENT_REQUIRES): Remove.
7300 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
7301 %code "requires" and %code "provides".
7302 * tests/input.at (Reject bad %code qualifiers): New.
7303
7304 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7305
7306 Use the new code_props interface for destructors and printers.
7307 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
7308 printer_location members, and change the type of the destructor and
7309 printer members to code_props.
7310 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
7311 symbol_printer_get, semantic_type_destructor_set,
7312 semantic_type_printer_set, default_tagged_destructor_set,
7313 default_tagless_destructor_set, default_tagged_printer_set,
7314 default_tagless_printer_set): Use code_props in arguments and return
7315 types in place of char const * and location.
7316 (symbol_destructor_location_get, symbol_printer_location_get): Remove
7317 since the locations are now contained in the return of
7318 symbol_destructor_get and symbol_printer_get.
7319 * src/output.c (symbol_destructors_output, symbol_printers_output):
7320 Replace with...
7321 (symbol_code_props_output): ... this to eliminate duplicate code.
7322 (output_skeleton): Update to use symbol_code_props_output.
7323 * src/reader.c (symbol_should_be_used): Update use of
7324 symbol_destructor_get.
7325 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
7326 Update uses of the various _destructor_set and _printer_set functions.
7327 * src/symtab.c: (default_tagged_destructor_location,
7328 default_tagless_destructor_location, default_tagged_printer_location,
7329 default_tagless_printer_location): Remove since we...
7330 (default_tagged_destructor, default_tagless_destructor,
7331 default_tagged_printer, default_tagless_printer): ... change the type
7332 of these to code_props.
7333 (symbol_new, semantic_type_new, symbol_destructor_set,
7334 semantic_type_destructor_set, symbol_destructor_get,
7335 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
7336 symbol_check_alias_consistency, default_tagged_destructor_set,
7337 default_tagless_destructor_set, default_tagged_printer_set,
7338 default_tagless_printer_set): Update.
7339 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
7340 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
7341 code_props members.
7342 (symbol_print): Use SYMBOL_CODE_PRINT.
7343
7344 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7345
7346 Use the new code_props interface for rule actions.
7347 * src/symlist.h (symbol_list): Replace action, action_location, and
7348 used members with a code_props action_props member.
7349 * src/reader.c (symbol_should_be_used, grammar_rule_check,
7350 grammar_midrule_action, grammar_current_rule_merge_set,
7351 grammar_current_rule_symbol_append, packgram): Update.
7352 * src/scan-code.h (translate_rule_action): Remove, no longer used.
7353 * src/scan-code.l (handle_action_dollar): Update.
7354 (translate_rule_action): Remove, no longer used.
7355 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
7356
7357 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7358
7359 Use the new code_props interface in parse-gram.y.
7360 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
7361 Update all uses of translate_* functions to use the new code_props
7362 interface and to use gram_scanner_last_string_free and
7363 code_scanner_last_string_free where possible.
7364 (grammar_declaration): symbol_list_destructor_set and
7365 symbol_list_printer_set now perform the translation, so don't do it
7366 here. Use gram_scanner_last_string_free where possible.
7367 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
7368 translate_code): Remove, no longer used.
7369 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
7370 symbol_list_printer_set): Perform code translation here rather than
7371 depending on the caller to do so.
7372
7373 * src/symlist.h (struct symbol_list): Correct some documentation typos.
7374 * src/scan-gram.h (gram_last_string): Remove declaration.
7375 * src/scan-gram.l (last_string): Declare it static.
7376
7377 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7378
7379 Encapsulate code properties and related functionality for the various
7380 destructors, printers, and actions into a code_props structure and
7381 interface. This patch merely implements code_props in scan-code.h and
7382 scan-code.l. Future patches will rewrite other modules to use it.
7383 Discussed starting at
7384 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
7385 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
7386 consistently initialize const structs that have an empty location
7387 field.
7388 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
7389 to ensure consistency.
7390 * src/scan-code.h (code_props): New structure.
7391 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
7392 function, macro, and const global variable for initializing a
7393 code_props with no code.
7394 (code_props_plain_init, code_props_symbol_action_init,
7395 code_props_rule_action_init, code_props_translate_code): The rest of
7396 the new code_props functional interface. Among other things, the init
7397 functions set the code_props kind field so that
7398 code_props_translate_code will know whether to behave like
7399 translate_symbol_action, translate_rule_action, or translate_code.
7400 These old translate functions must remain until all other modules are
7401 updated to use the new code_props interface.
7402 (code_scanner_last_string_free): New function similar to
7403 gram_scanner_last_string_free.
7404 (code_scanner_free): Add documentation.
7405 * src/scan-code.l: Implement the new interface.
7406 (code_lex): Make it static, add a code_props* argument, and remove the
7407 rule argument.
7408 (last_string): New static global similar to the one in scan-gram.l.
7409 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
7410 instead of rule.
7411 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
7412 code_props since Bison may one day use this information for destructors
7413 and printers.
7414 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
7415 (handle_action_dollar): Use symbol_list_n_get and set used flag
7416 directly since symbol_list_n_used_set is removed.
7417 (translate_action): Add a code_props* argument and remove the rule,
7418 action, and location arguments. Pass the code_props* on to code_lex.
7419 (translate_rule_action, translate_symbol_action, translate_code):
7420 Rewrite as wrappers around the new code_props interface.
7421 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
7422 it would eventually need to break the encapsulation of code_props.
7423
7424 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7425
7426 * etc/.cvsignore: New.
7427
7428 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7429
7430 Add maintainer-push-check to run maintainer-check using push parsing in
7431 place of pull parsing where available.
7432 * Makefile.am (maintainer-push-check): New.
7433 * data/bison.m4 (b4_use_push_for_pull_if): New.
7434 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
7435 appropriately based on their existing values.
7436 (yypush_parse): Don't print push-parser-specific diagnostics if push
7437 parsing is being used in place of pull parsing.
7438 * data/yacc.c: If push parsing should replace pull parsing, redirect to
7439 push.c.
7440 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
7441 variable, and insert b4_use_push_for_pull_flag into muscles.
7442 * tests/Makefile.am (maintainer-push-check): New.
7443
7444 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
7445
7446 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
7447 (whether successful or failed) so that yypush_parse can be invoked
7448 again to start a new parse using the same yypstate.
7449 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
7450 check multiple yypull_parse invocations on the same yypstate. For pull
7451 mode, extend to check multiple yyparse invocations.
7452 (Exploding the Stack Size with Alloca): Extend to try with
7453 %push-pull-parser.
7454 (Exploding the Stack Size with Malloc): Likewise.
7455
7456 * tests/calc.at (Simple LALR Calculator): Don't specify
7457 %skeleton "push.c" since %push-pull-parser implies that now.
7458 * tests/headers.at (export YYLTYPE): Don't check for the push
7459 declarations. Otherwise, this test case can't be used to see if push
7460 mode can truly emulate pull mode.
7461 * tests/input.at (Torturing the Scanner): Likewise.
7462 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
7463 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
7464 AT_YACC_IF, which now includes the case of push mode since %skeleton
7465 need not be used for push mode. This will be more intuitive once
7466 push.c is renamed to yacc.c.
7467
7468 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
7469
7470 For push mode, convert yyparse from a macro to a function, invoke yylex
7471 instead of passing a yylexp argument to yypull_parse, and don't
7472 generate yypull_parse or yyparse unless %push-pull-parser is declared.
7473 Discussed starting at
7474 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
7475 * data/bison.m4 (b4_pull_if): New.
7476 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
7477 * data/push.c: Improve M4 quoting a little.
7478 (b4_generate_macro_args, b4_parenthesize): Remove.
7479 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
7480 any time a pull parser is requested.
7481 Don't #define this as a wrapper around yypull_parse. Instead, when
7482 both push and pull are requested, make it a function that does that
7483 same thing.
7484 (yypull_parse): If there's a b4_prefix, #define this to
7485 b4_prefix[pull_parse] when both push and pull are requested.
7486 Don't define this as a function unless both push and pull are
7487 requested.
7488 Remove the yylexp argument and hard-code yylex invocation instead.
7489 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
7490 %push-parser.
7491 * src/getargs.c (pull_parser): New global initialized to true.
7492 * getargs.h (pull_parser): extern it.
7493 * src/output.c (prepare): Insert pull_flag muscle.
7494 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
7495 (prologue_declaration): Set both push_parser and pull_parser = true for
7496 %push-pull-parser. Set push_parser = true and pull_parser = false for
7497 %push-parser.
7498 * src/scan-gram.l: Don't accept %push_parser as an alternative to
7499 %push-parser since there's no backward-compatibility concern here.
7500 Scan %push-pull-parser.
7501 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
7502 instead of %push-parser.
7503 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
7504 prototype it in the module that calls yyparse.
7505 * tests/input.at (Torturing the Scanner): Likewise.
7506 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
7507
7508 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
7509
7510 Update etc/bench.pl. Optimize push mode a little (the yyn change
7511 deserves most of the credit).
7512 * Makefile.am (SUBDIRS): Add etc subdirectory.
7513 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
7514 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
7515 yytoken, yyval, and yyloc declarations to...
7516 (yyparse or yypush_parse): ... here to improve performance. For
7517 yypush_parse invocations after the first, be sure to assign yyn its old
7518 value again.
7519 (yypstate_new): Don't bother initializing the yyresult field since the
7520 initial value isn't used.
7521 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
7522 remove the #define that, in push mode, set it to yyps->NAME.
7523 * etc/Makefile.am: New.
7524 * etc/bench.pl: Remove and build it instead from...
7525 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
7526 "tests/bison" from the build directory by default rather than just
7527 invoking "bison" from $PATH.
7528 (calc_grammar): Update push parser code: don't declare yylval globally,
7529 don't define yyparse_wrapper, and don't #define yyparse.
7530 (bench_grammar): Update to check all working combinations of yacc.c,
7531 push.c, impure, pure, pull, and push.
7532
7533 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
7534
7535 For push mode, add pull wrappers around yypush_parse.
7536 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
7537 (yypull_parse): New function wrapping yypush_parse.
7538 (yyparse): New #define wrapping yypull_parse.
7539 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
7540 is declared.
7541 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
7542 prototype yylex in the module that calls yyparse, and don't prototype
7543 yyparse there. Otherwise, the yyparse expansion won't compile.
7544 * tests/input.at (Torturing the Scanner): Likewise.
7545
7546 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
7547
7548 Enable push parsers to operate in impure mode. Thus, %push-parser no
7549 longer implies %pure-parser. The point of this change is to move
7550 towards being able to test the push parser code by running the entire
7551 test suite as if %push-parser had been declared.
7552 * data/push.c (yypush_parse): For impure mode, remove the
7553 yypushed_char, yypushed_val, and yypushed_loc arguments.
7554 Instead, declare these as local variables initialized to the global
7555 yychar, yylval, and yylloc.
7556 For the first yypush_parse invocation only, restore the initial values
7557 of these global variables when it's time to read a token since they
7558 have been overwritten.
7559 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
7560 %push-parser.
7561 * tests/calc.at (Simple LALR(1) Calculator): Always declare
7562 %pure-parser along with %push-parser since this test case was designed
7563 for pure push parsers.
7564 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
7565 (AT_YACC_OR_PUSH_IF): New.
7566 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
7567 add a note that it's still wrong for some cases (as it has been for a
7568 while).
7569 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
7570 %push-parser no longer implies %pure-parser.
7571
7572 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7573
7574 Remove some unnecessary differences between the pull parser code and
7575 the push parser code. This patch enables yynerrs in push mode.
7576 * data/push.c: Reformat M4 a little.
7577 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
7578 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
7579 because push mode is on. Instead, if pure mode is on, move yynerrs
7580 to...
7581 (b4_declare_parser_state_variables): ... here.
7582 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
7583 to yyps->NAME so it can be used in yypush_parse.
7584 (yypush_parse): Don't omit uses of yynerrs in push mode.
7585
7586 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7587
7588 Fix bug such that the first pushed token's value and location are
7589 sometimes overwritten (sometimes by %initial-action) before being used.
7590 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
7591 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
7592 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
7593 more closely mimic the pull parser logic.
7594 Don't copy the pushed token to yychar, yylval, and yylloc until it's
7595 time to read a token, which is after any initialization of yylval and
7596 yylloc.
7597 (gottoken): Rename label to...
7598 (yyread_pushed_token): ... for clarity and to avoid infringing on the
7599 user namespace.
7600
7601 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7602
7603 Rearrange initialization of the parser state variables so that the
7604 skeleton doesn't have to have a copy for pull mode and another for push
7605 mode. This patch also fixes at least a bug such that yylloc was not
7606 initialized (with b4_location_initial_line and
7607 b4_location_initial_column) upon calling yypush_parse. However, that
7608 initialization now overwrites the first token's location;
7609 %initial-action assigning @$ already did the same thing, and both bugs
7610 will be fixed in a later patch.
7611 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
7612 (b4_declare_parser_state_variables): Remove initialization of yytoken,
7613 yyss, yyvs, yyls, and yystacksize.
7614 (yypstate_new): Remove initialization of some yypstate fields: yystate,
7615 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
7616 yylsp.
7617 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
7618 yyps->NAME so it can be used in yypush_parse.
7619 (yyparse or yypush_parse): For yypush_parse, don't print the
7620 "Starting parse" diagnostic for invocations after the first.
7621 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
7622 yypush_parse, only do it for the first invocation.
7623 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
7624 initialization to occur in yypush_parse but only on the first
7625 invocation.
7626
7627 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7628
7629 * data/push.c: Add CPP guards around push parser declarations in both
7630 the header and the code file.
7631 In the code file, move the push parser declarations to the same place
7632 they appear in the header file.
7633 Clean up the M4 some, especially the inconsistent underquoting in
7634 some b4_c_function_def and b4_c_function_decl uses.
7635
7636 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7637
7638 Encapsulate the push parser state variables into an M4 macro so the
7639 push skeleton doesn't have to list them again for pull mode's yyparse.
7640 For push mode, remove yypush_parse's local equivalents of these
7641 variables to eliminate unnecessary copying between the two sets at
7642 run-time. This patch also fixes at least a bug related to multiple
7643 %initial-action invocations in push mode.
7644 * data/push.c (b4_declare_parser_variables): Rename to...
7645 (b4_declare_scanner_communication_variables): ... this for clarity and
7646 update both uses.
7647 (b4_declare_yyparse_variables): Remove and move its contents to the one
7648 spot where it was invoked.
7649 (b4_declare_parser_state_variables): New macro containing the parser
7650 state variables required by push mode.
7651 (struct yypstate): Replace all fields but yynew with
7652 b4_declare_parser_state_variables.
7653 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
7654 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
7655 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
7656 (yyparse or yypush_parse): For yyparse in pull mode, replace local
7657 parser state variable declarations with
7658 b4_declare_parser_state_variables.
7659 Don't initialize parser state variables when calling yypush_parse since
7660 yypstate_new already does that.
7661 Invoke the user's initial action only upon the first yypush_parse
7662 invocation.
7663 Remove all code that copies between the local parser state variables
7664 and the yypstate.
7665
7666 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7667
7668 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
7669 prevent a name collision in a future patch where these names will
7670 sometimes be #define'd.
7671 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
7672 since it no longer has the same name as the existing argument.
7673 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
7674
7675 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
7676 and Joel E. Denny <jdenny@ces.clemson.edu>
7677
7678 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
7679 that the argument is case-insensitive, and there's no `=' here.
7680 For the %skeleton entry, mention that %language is better.
7681 (Bison Options): Likewise for --language and --skeleton. Move the
7682 --skeleton entry so that the `Tuning the parser' section is sorted
7683 alphabetically on long options.
7684 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
7685 %language directive in detail here; cross-reference the %language
7686 documentation instead.
7687 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
7688 `%require "2.3b"' so that the example is always up-to-date.
7689 (Table of Symbols): Add entries for %language and %skeleton.
7690 * examples/extexi (normalize): Instead of replacing every %require
7691 argument with the current Bison version, just substitute for
7692 `@value{VERSION}'. This guarantees that we're testing what actually
7693 appears in the documentation.
7694 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
7695 rather than `@VERSION@'.
7696
7697 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7698
7699 * NEWS: Reword the %language news a bit, and put it earlier.
7700
7701 * src/getargs.c (skeleton_arg): Last arg is now location const *.
7702 Rewrite to simplify the logic.
7703 (language_argmatch): Likewise.
7704 (program_name): We now own this var.
7705 * src/getargs.h (struct bison_language): Use char[] rather than
7706 const char *.
7707
7708 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
7709 Java is supported.
7710 * src/complain.c (program_name): Remove decl; no longer needed.
7711 * src/main.c (program_name): Remove; now belongs to getargs.
7712
7713 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
7714
7715 * NEWS: Document %language.
7716
7717 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
7718
7719 * data/c-skel.m4, data/c++-skel.m4: New files.
7720 * data/glr.c: Complain on push parsers.
7721
7722 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
7723 over %skeleton.
7724 (Decl Summary): Document %language and %skeleton.
7725 (Command line): Document -L.
7726
7727 * examples/extexi: Rewrite %require directive.
7728 * examples/calc++/Makefile.am: Pass VERSION to extexi.
7729
7730 * src/files.c (compute_exts_from_gc): Look in language structure
7731 for .y extension.
7732 (compute_file_name_parts): Check whether .tab should be added.
7733 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
7734 (language, skeleton_arg, language_argmatch): New.
7735 (long_options): Add --language.
7736 (getargs): Use skeleton_arg, add -L/--language.
7737 * src/getargs.h: Include location.h.
7738 (struct bison_language, language, skeleton_arg, language_argmatch): New.
7739 * src/output.c (prepare): Pick default skeleton from struct language.
7740 Don't dispatch C skeletons here.
7741 * src/parse-gram.y (PERCENT_LANGUAGE): New.
7742 (prologue_declaration): Add "%language" rule, use skeleton_arg.
7743 * src/scan-gram.l ("%language"): New rule.
7744
7745 * tests/calc.at: Test %skeleton and %language.
7746 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
7747 (AT_GLR_IF): Look for %skeleton "glr.cc".
7748 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
7749 (AT_YACC_IF): Reject %language.
7750
7751 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7752
7753 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
7754 since it wasn't used; only the typedef name 'semantic_type' is needed.
7755 Also, omit trailing white space.
7756
7757 * bootstrap: Sync from coreutils.
7758 (gnulib_extra_files): Add build-aux/announce.gen.
7759 (slurp): Adjust .gitignore files like .cvsignore files.
7760 * build-aux/announce-gen: Remove from CVS, since bootstrap
7761 now creates this.
7762
7763 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
7764
7765 Make %push-parser imply %pure-parser. This fixes several bugs; see
7766 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
7767 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
7768 pure_parser = true.
7769 * data/push.c: Don't bother testing b4_push_if when deciding whether
7770 to expand b4_declare_parser_variables globally.
7771 (yypush_parse): Likewise in here.
7772
7773 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
7774 (yy_reduce_print): Reformat M4 for readability.
7775
7776 2006-12-15 Bob Rossi <bob@brasko.net>
7777 and Joel Denny <jdenny@ces.clemson.edu>
7778
7779 * data/push.c (yypstate): Add typedef, and update all uses of
7780 struct yypstate to just yypstate.
7781 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
7782
7783 2006-12-14 Bob Rossi <bob@brasko.net>
7784
7785 * data/push.c (yypush_parse): Declare prototype regardless of
7786 %locations option.
7787
7788 2006-12-14 Bob Rossi <bob@brasko.net>
7789
7790 * data/push.c (yyparse): Remove the prototype and the #define when in
7791 push-parser mode.
7792
7793 2006-12-13 Bob Rossi <bob@brasko.net>
7794
7795 * data/push.c (yypstate_init): Rename to...
7796 (yypstate_new): ... this and use b4_c_function_def.
7797 (yypstate_delete): New.
7798 (yypush_parse): Change parameters yynval and yynlloc to be const.
7799 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
7800 yypstate_delete functions.
7801
7802 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
7803
7804 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
7805 strange test case titles. Reported by Bob Rossi.
7806
7807 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
7808
7809 * TODO: Add pointer to Sylvain Schmitz's work on static detection
7810 of potential ambiguities in GLR grammers.
7811
7812 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
7813
7814 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
7815 `bison ', use m4_index instead of m4_substr since chopping up a string
7816 containing M4-special characters causes problems here.
7817
7818 Fix a couple of bugs related to special characters in user-specified
7819 file names, and make it easier for skeletons to compute output file
7820 names with the same file name prefix as Bison-computed output file
7821 names.
7822 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
7823 b4_parser_file_name and b4_spec_defines_file instead of
7824 @output_parser_name@ and @output_header_name@, which are now redundant.
7825 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
7826 b4_parser_file_name, b4_spec_defines_file, and the new
7827 @basename(FILENAME@) instead of @output_parser_name@ and
7828 @output_header_name@, which inappropriately escaped the file names as
7829 C string literals.
7830 * src/files.c (all_but_ext): Remove static qualifier.
7831 (compute_output_file_names): Move `free (all_but_ext)' to...
7832 (output_file_names_free): ... here since all_but_ext is needed later.
7833 * src/files.h (all_but_ext): Extern.
7834 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
7835 exactly what MUSCLE_INSERT_STRING used to do.
7836 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
7837 characters are escaped properly.
7838 * src/output.c (prepare): Define muscle file_name_all_but_ext as
7839 all_but_ext.
7840 For pkgdatadir muscle, maintain previous functionality by using
7841 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
7842 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
7843 digraphs would never be expanded. Hopefully no one has M4-special
7844 characters in his Bison installation path.
7845 * src/scan-skel.l: Don't parse @output_header_name@ and
7846 @output_parser_name@ anymore since they're now redundant.
7847 In @output, use decode_at_digraphs.
7848 Parse a new @basename command that invokes last_component.
7849 (decode_at_digraphs): New.
7850 (BASE_QPUTS): Remove unused.
7851 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
7852 (Output file name): New tests.
7853
7854 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
7855
7856 Warn about output files that are generated by the skeletons and that
7857 conflict with other output files.
7858 * data/glr.c: Don't generate the header file here when glr.cc does.
7859 * src/files.c (file_names, file_names_count): New static globals.
7860 (compute_output_file_names): Invoke output_file_name_check for files
7861 not generated by the skeletons and remove existing checks.
7862 (output_file_name_check): New function that warns about conflicting
7863 output file names.
7864 (output_file_names_free): Free file_names.
7865 * src/files.h (output_file_name_check): Declare.
7866 * src/scan-skel.l: Invoke output_file_name_check for files generated by
7867 the skeletons.
7868 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
7869 (Conflicting output files): New tests.
7870
7871 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7874
7875 2006-12-08 Bob Rossi <bob@brasko.net>
7876
7877 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
7878 Rename to...
7879 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
7880 update all uses.
7881 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
7882 (yypush_parse): Rename yypvars argument to yyps and remove redundant
7883 local pv.
7884 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
7885 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
7886
7887 2006-12-07 Bob Rossi <bob@brasko.net>
7888 and Joel Denny <jdenny@ces.clemson.edu>
7889
7890 * data/push.c (yypvarsinit): Change return type from void* to struct
7891 yypvars*. No longer cast to void* on return.
7892 (struct yypvars): Remove yylen since it need not be remembered between
7893 yypushparse invocations.
7894 (yypushparse): Don't copy between yylen and pv->yylen.
7895
7896 2006-12-05 Bob Rossi <bob@brasko.net>
7897
7898 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
7899 (yypushparse): Add yynchar, yynlval, yynlloc parameters.

7904 push or pure mode.
7905 (yypushparse): Add b4_declare_parser_variables.
7906 Init new local variables, and remove init code for removed
7907 yypvars variables.
7908 (yyparse): Delete.
7909 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
7910 and yyparse for other modes.
7911 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
7912 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
7913 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
7914 (AT_PURE_LEX_IF): True if pure or push parser.
7915

7917
7918 Document Yacc prologue alternatives and default %destructor's and
7919 %printer's as experimental. Don't mention Java yet. Discussed at
7920 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
7921 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
7922 (2.3a): Annotate this entry to say the old forms of these features were
7923 also experimental.
7924 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
7925 Table of Symbols): Say they're experimental. Comment out any mention
7926 of Java (we'll want this back eventually).
7927
7928 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
7929
7930 Support a file name argument to %defines. Deprecate `=' in
7931 %file-prefix, %name-prefix, and %output. Discussed at
7932 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
7933 * NEWS (2.3a+): Mention.
7934 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
7935 form of %defines, and remove `=' from entries for %file-prefix,
7936 %name-prefix, and %output.
7937 * src/parse-gram.y (prologue_declaration): Implement.
7938 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
7939 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
7940 all but one occurrence of %name-prefix.
7941 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
7942 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
7943 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
7944 occurrence of each of %file-prefix and %output. Add check for %defines
7945 with argument.
7946 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
7947 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
7948 Remove the `=' from %output.
7949
7950 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
7951
7952 Don't escape $ in test case titles since Autoconf 2.61 now does that
7953 correctly.
7954 * tests/actions.at (Default %printer and %destructor are not for error
7955 or $undefined): Here.
7956 (Default %printer and %destructor are not for $accept): Here.
7957 * tests/input.at (Invalid $n and @n): Here.
7958
7959 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
7960
7961 Rename <!> to <>. Discussed starting at
7962 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
7963 * NEWS (2.3a+): Update.
7964 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
7965 Update.
7966 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
7967 * src/scan-gram.l (INITIAL): Implement.
7968 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
7969 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
7970 comment.
7971 * tests/actions.at (Default tagless %printer and %destructor,
7972 Default tagged and per-type %printer and %destructor,
7973 Default %printer and %destructor are not for error or $undefined,
7974 Default %printer and %destructor are not for $accept,
7975 Default %printer and %destructor for mid-rule values): Update.
7976 * tests/input.at (Default %printer and %destructor redeclared,
7977 Unused values with default %destructor): Update.
7978
7979 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
7980
7981 Don't let %prec take a nonterminal.
7982 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
7983 token.
7984 * tests/input.at (%prec takes a token): New test checking that %prec
7985 won't take a nonterminal.
7986
7987 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
7988
7989 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
7990 it was double-quoted.
7991 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
7992 grammar is maintained with Bison's highest standards.
7993 * src/getargs.c: Fix some typos in Doxygen comments.
7994
7995 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
7996
7997 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
7998 later. Reported by Paul Eggert in
7999 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
8000 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
8001 * src/scan-code.l (translate_action): Don't bother invoking
8002 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
8003 (code_scanner_free): Instead of invoking
8004 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
8005 which frees more.
8006 * src/scan-gram.l (gram_scanner_free): Likewise.
8007 * src/scan-skel.l (scan_skel): Likewise.
8008
8009 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
8010
8011 * src/files.c (tr): Change return type to void.
8012 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
8013 has been called previously for the same key.
8014 (muscle_find): Return storage instead of value so that
8015 --enable-gcc-warnings doesn't produce warnings that the return discards
8016 const. aver that the value and storage are the same since storage
8017 could potentially be NULL when value is not.
8018 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
8019 same as 0.
8020
8021 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8022
8023 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
8024 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
8025 us a slightly cleaner distribution, and also works.
8026 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
8027 gnulib changes.
8028
8029 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
8030 and Paul Eggert <eggert@cs.ucla.edu>
8031
8032 Don't let Bison leak memory except when it complains.
8033 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
8034 (spec_defines_file, dir_prefix): Now char *, not const char *,
8035 since they are freed.
8036 * src/files.c: Likewise.
8037 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
8038 Likewise.
8039 (tr): Now operates in-place. All uses changed.
8040 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
8041 values.
8042 (compute_file_name_parts, compute_output_file_names): Don't store
8043 read-only data in variables that will be freed.
8044 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
8045 src_extension, and header_extension.
8046 (output_file_names_free): New public function to free
8047 spec_verbose_file, spec_graph_file, spec_defines_file,
8048 parser_file_name, and dir_prefix.
8049 * src/getargs.c (getargs): Don't store read-only data in variables that
8050 will be freed.
8051 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
8052 (which previously existed but was unused), and quotearg_free.
8053 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
8054 * src/muscle_tab.c: Likewise.
8055 (muscle_entry): Make the value char const *,
8056 and add a new storage member that is char * and can be freed.
8057 (muscle_entry_free): New private function.
8058 (muscle_init): Use it instead of free.
8059 (muscle_insert, muscle_grow): Update and use new storage member.
8060 (muscle_code_grow): Free the string passed to muscle_grow
8061 since it's not needed anymore.
8062 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
8063 add a new `char *code' member.
8064 ("{...}"): Declare semantic type as code.
8065 * src/scan-code.h (translate_rule_action):
8066 (translate_symbol_action, translate_code, translate_action): Return
8067 `char const *' rather than `char *' since external code should not free
8068 these strings.
8069 * src/scan-code.l: Likewise.
8070 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
8071 which is "{...}" in the parser.
8072 * tests/Makefile.am (maintainer-check-valgrind): Set
8073 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
8074 Valgrind.
8075 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
8076 complain.
8077 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
8078 expecting a non-zero exit status sets --leak-check=summary and
8079 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
8080 this case, and we don't want to hear about it.
8081
8082 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8083
8084 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
8085 instead of from the template, to simplify configuration a bit.
8086 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
8087 and m4/wint_t.m4, as they are needed with the latest gnulib.
8088
8089 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8090
8091 Disable unset/unused mid-rule value warnings by default, and recognize
8092 --warnings=midrule-values to enable them. Discussed starting at
8093 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
8094 * NEWS (2.3a+): Mention.
8095 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
8096 warnings): Add entry for midrule-values subargument.
8097 * src/reader.c (symbol_should_be_used): Don't return true just because
8098 the value is a set/used mid-rule value unless
8099 --warnings=midrule-values was specified.
8100 * tests/input.at (Unused values, Unused values before symbol
8101 declarations): Run tests with and without --warnings=midrule-values.
8102
8103 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
8104 than LIST_FREE directly.
8105
8106 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8107
8108 Finish implementing --warnings=error, which should not be implied by
8109 --warnings=all (or by its synonyms -W and --warnings without
8110 subarguments).
8111 * src/complain.c (set_warning_issued): New function to report that
8112 warnings are being treated as errors and to record an error if so.
8113 Invoke...
8114 (warn_at, warn): ... here.
8115 * src/getargs.c (warnings_args, warnings_types): Reorder so that
8116 "error - warnings are errors" does not appear above "all - all of the
8117 above".
8118 (getargs): For -W and --warnings without subarguments, don't let
8119 FLAGS_ARGMATCH set warnings_error in warnings_flag.
8120 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
8121
8122 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
8123
8124 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
8125 empty subargument list. For example: `bison --warnings= parser.y'.
8126
8127 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8128
8129 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
8130 the parser header file so that gcc doesn't warn.
8131
8132 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8133
8134 Split the default %destructor/%printer into two kinds: <*> and <!>.
8135 Discussed starting at
8136 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
8137 * NEWS (2.3a+): Mention.
8138 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
8139 previous change today related to mid-rules.
8140 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
8141 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
8142 (TYPE_TAG_ANY): Add as <*>.
8143 (TYPE_TAG_NONE): Add as <!>.
8144 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
8145 for <*> and <!>.
8146 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
8147 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
8148 * src/symlist.c (symbol_list_default_new): Split into tagged and
8149 tagless versions.
8150 (symbol_list_destructor_set, symbol_list_printer_set): Split
8151 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
8152 SYMLIST_DEFAULT_TAGLESS.
8153 * src/symlist.h: Update symbol_list_default*_new prototypes.
8154 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
8155 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
8156 * src/symtab.c (default_destructor, default_destructor_location,
8157 default_printer, default_printer_location): Split each into tagged and
8158 tagless versions.
8159 (symbol_destructor_get, symbol_destructor_location_get,
8160 symbol_printer_get, symbol_printer_location_get): Implement tagged
8161 default and tagless default cases.
8162 (default_destructor_set, default_printer_set): Split each into tagged
8163 and tagless versions.
8164 * src/symtab.h: Update prototypes.
8165 * tests/actions.at (Default %printer and %destructor): Rename to...
8166 (Default tagless %printer and %destructor): ... this, and extend.
8167 (Per-type %printer and %destructor): Rename to...
8168 (Default tagged and per-type %printer and %destructor): ... this, and
8169 extend.
8170 (Default %printer and %destructor for user-defined end token): Extend.
8171 (Default %printer and %destructor are not for error or $undefined):
8172 Update.
8173 (Default %printer and %destructor are not for $accept): Update.
8174 (Default %printer and %destructor for mid-rule values): Extend.
8175 * tests/input.at (Default %printer and %destructor redeclared): Extend.
8176 (Unused values with default %destructor): Extend.
8177
8178 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
8179
8180 Don't apply the default %destructor/%printer to an unreferenced midrule
8181 value. Mentioned at
8182 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
8183 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
8184 like $@n instead of just @n so that the default %destructor/%printer
8185 logic doesn't see them as user-defined symbols.
8186 (symbol_is_dummy): Check for both forms of the name.
8187 * src/reader.c (packgram): Remove the `$' from each midrule symbol
8188 name for which the midrule value is referenced in any action.
8189 * tests/actions.at (Default %printer and %destructor for mid-rule
8190 values): New test.
8191 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
8192 for change to dummy symbol names.
8193
8194 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
8195
8196 Warn about unset midrule $$ if the corresponding $n is used.
8197 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
8198 $n usage.
8199 (packgram): Before invoking grammar_rule_check on any rule, make sure
8200 all actions have already been scanned in order to set `used' flags.
8201 Otherwise, checking that a midrule's $$ is set will not always work
8202 properly because the midrule check must forward-reference the midrule's
8203 parent rule.
8204 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
8205 warning.
8206
8207 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
8208
8209 More improvements to the documentation of the prologue alternatives:
8210 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
8211 Bison manual.
8212 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
8213 some text to clarify the relative importance of the new directives and
8214 to show how these directives may be viewed as code labels.
8215
8216 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
8217
8218 Similar to the recently removed %before-header, add %code-top as the
8219 alternative to the pre-prologue. Mentioned at
8220 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
8221 Also, let the prologue alternatives appear in the grammar section.
8222 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
8223 (prologue_declaration): Move the existing prologue alternatives to...
8224 (grammar_declaration): ... here and add %code-top.
8225 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
8226
8227 Clean up and extend documentation for the prologue alternatives.
8228 * NEWS (2.3a+): Describe prologue alternatives.
8229 * doc/bison.texinfo (Prologue): Move discussion of prologue
8230 alternatives to...
8231 (Prologue Alternatives): ... this new section, and extend it to discuss
8232 all 4 directives in detail.
8233 (Table of Symbols): Clean up discussion of prologue alternatives and
8234 add %code-top.

8236 2006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
8237
8238 DJGPP specific issues.
8239
8240 * djgpp/config.bat: config.hin has been moved to lib. Adjust
8241 config.bat accordingly.
8242 * djgpp/config.sed: Adjust config.sed for the use of autoconf 2.60.
8243 * djgpp/config.site: Likewise.
8244
8245 2006-10-16 Paolo Bonzini <bonzini@gnu.org>
8246
8247 Replace %*-header with %provides, %requires, %code. See discussion at
8248 http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00002.html
8249
8250 * data/bison.m4 (b4_user_requires, b4_user_provides): New.
8251 (b4_user_start_header): Remove.
8252 * data/glr.c: Use new macros instead of b4_*start_header
8253 and b4_*end_header.
8254 * data/glr.cc: Likewise.

8263 * src/scan-gram.l: Likewise.
8264 * tests/actions.at: Likewise.
8265
8266 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8267
8268 * lib/Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS).
8269 Problem reported by Joel E. Denny.
8270
8271 2006-10-14 Jim Meyering <jim@meyering.net>
8272
8273 (Sync from coreutils.)
8274 Work also when the working directory (with e.g. coreutils sources)
8275 is version controlled with git, rather than CVS.
8276 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
8277 rather than CVS.
8278 In messages and comments, say e.g., "checked-out sources",
8279 rather than "CVS sources".
8280 (version_controlled_file): New function. Work for git as well as
8281 for CVS. Don't use grep's -q option.
8282 (slurp): Call it here, in place of CVS-specific code.
8283
8284 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
8285
8286 Fix testsuite for ./configure --enable-gcc-warnings:
8287 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
8288 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
8289 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
8290 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
8291 * test/regression.at (Diagnostic that expects two alternatives):
8292 Likewise.
8293
8294 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8295
8296 * bootstrap.conf (gnulib_modules): Add config-h.

8317 Adjust expected line numbers in output to reflect removal of #if
8318 HAVE_CONFIG_H lines.
8319 * tests/glr-regression.at (Missed %merge type warnings when ...):
8320 Likewise.
8321 * tests/regression.at (Braced code in declaration in rules section):
8322 Likewise.
8323 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
8324 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
8325 Include <config.h> unconditionally.
8326
8327 * bootstrap: Sync from coreutils, as follows:
8328
8329 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8330
8331 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
8332 variable was sometimes used without being initialized. This
8333 messed up the installation of the INSTALL file in some cases.
8334
8335 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8336
8337 * bootstrap (usage, main program, symlink_to_gnulib): Add option
8338 --copy. Inspired by a suggestion from Bruno Haible.
8339
8340 2006-10-03 Jim Meyering <jim@meyering.net>
8341
8342 * bootstrap: Undo last change to this file, since now gnulib-tool
8343 sticks with the automake default in generating dependencies.
8344
8345 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8346
8347 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
8348 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
8349
8350 * doc/bison.1: Add copyright notice.
8351
8352 * data/glr.c: Don't include <stdarg.h>; not used.
8353
8354 * NEWS: The -g and --graph options now output graphs in Graphviz
8355 DOT format, not VCG format.
8356 * doc/bison.1: Likewise.
8357 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
8358 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
8359 of this change in
8360 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
8361 * TODO: Remove Graphviz entry.

8371 * src/print_graph.c: Include graphviz.h rather than vcg.h.
8372 (static_graph, fgraph): Remove. All uses changed to pass
8373 arguments instead of sharing a static var.
8374 (print_core, print_actions, print_state, print_graph):
8375 Output graphviz format rather than VCG format.
8376 * tests/.cvsignore: Remove *.vcg; add *.dot.
8377 * tests/output.at: Expect *.dot files, not *.vcg files.
8378
8379 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
8380 accommodates the 2006-10-08 change.
8381
8382 2006-10-11 Bob Rossi <bob@brasko.net>
8383

8389
8390 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8391
8392 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
8393 in a push parser. Reindent slightly to match yacc.c better.
8394
8395 2006-10-11 Bob Rossi <bob@brasko.net>
8396
8397 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
8398 yymsg_alloc fields.
8399 (yypvarsinit, yypushparse): Remove init of removed fields.
8400 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
8401
8402 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8403
8404 * THANKS: Add Paolo Bonzini and Bob Rossi.
8405
8406 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
8407
8408 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
8409 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
8410 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
8411 b4_define_user_cde and uses): Remove.
8412 (b4_comment, b4_prefix, b4_sync_start): New.
8413 * data/bison.m4: New file, with most of the content removed from c.m4.
8414 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
8415 * src/output.c (output_skeleton): Pass bison.m4.
8416 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
8417 only if specified.
8418
8419 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
8420
8421 Fix test failure reported by Tom Lane in
8422 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
8423 and try to make such failures easier to catch in the future.
8424 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
8425 that's now the caller's responsibility.
8426 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
8427 Set yychar = YYEOF if it's negative.
8428 * tests/actions.at (yylex): Abort if asked to read past EOF.
8429 * tests/conflicts.at (yylex): Likewise.
8430 * tests/cxx-type.at (yylex): Likewise.
8431 * tests/glr-regression.at (yylex): Likewise.
8432 * tests/input.at (yylex): Likewise.
8433 * tests/regression.at (yylex): Likewise.
8434 * tests/torture.at (yylex): Likewise.
8435
8436 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
8437
8438 Fix problems with translating English-language diagnostics.
8439 * bootstrap: Fix bug introduced in recent bootstrap changes, with
8440 respect to bison-runtime pot generation. The YY_ stuff
8441 wasn't being captured.
8442 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
8443 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
8444 * runtime-po/POTFILES.in: Add data/push.c.
8445
8446 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
8447
8448 Merge bootstrap changes from coreutils.
8449
8450 2006-09-28 Jim Meyering <jim@meyering.net>
8451
8452 Automatically generated dependencies are important even
8453 when all of the sources in a directory come from gnulib.
8454 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
8455 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
8456
8457 2006-09-23 Jim Meyering <jim@meyering.net>
8458
8459 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
8460
8461 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8462
8463 * bootstrap: Add support for --force.
8464 (usage): New function. Describe usage less tersely.
8465 (CVS_only_file): New var.
8466
8467 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
8468
8469 * data/push.c (YYPUSH_MORE): Make it an enum instead.
8470 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
8471 Adjust white space and comments to match GNU style better.
8472
8473 2006-09-20 Bob Rossi <bob@brasko.net>
8474
8475 * data/push.c (yyresult_get): Remove function.
8476 (YYPUSH_MORE): Add #define.
8477 (yypushparse): Modify return value.
8478
8479 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8480
8481 * stamp-h.in: Remove; no longer needed.
8482 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
8483 Remove config.h, config.hin, intl (no longer created).
8484 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
8485 stamp-h1.
8486
8487 Sync bootstrap from coreutils, as follows:
8488
8489 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
8490
8491 * bootstrap (symlink_to_gnulib): New function.
8492 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
8493 to copies-of-gnulib.
8494 (cp_mark_as_generated, slurp, gnulib_files):
8495 Avoid making a copy if it's the same as the old version.
8496 (gnulib_files): Add support for this variable (used by Bison).
8497
8498 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8499
8500 * src/getargs.c (usage): Rework to use conventions similar to
8501 coreutils, to make translation a bit easier and the code a bit
8502 smaller. Problem reported by Tim Van Holder.
8503
8504 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
8505
8506 Use some of gnulib's new modules, taken from coreutils.
8507
8508 * bootstrap: Sync from coreutils, except add support for gnulib_files.
8509 * bootstrap.conf: New file.
8510 (gnulib_modules): Add configmake, inttypes, unistd.
8511 (XGETTEXT_OPTIONS): Add complain, complain_at,
8512 fatal, fatal_at, warn, warn_at, unexpected_end.
8513 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
8514 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
8515 (gl_EARLY): Add.
8516 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
8517 (gl_INIT): Add
8518 (GNULIB_AUTOCONF_SNIPPET): Remove.
8519 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
8520 the pickiest.
8521 * lib/.cvsignore: Add inttypes_.h.
8522 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
8523 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
8524 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
8525 no-longer-necessary initializations.
8526 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
8527 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
8528 use the unistd module.
8529 * src/system.h: Likewise.
8530 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
8531 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
8532 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
8533 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
8534 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
8535 * src/system.h: Include inttypes.h unconditionally, now that we
8536 use the inttypes module. Don't bother to include stdint.h, since
8537 inttypes.h now does that for us.
8538 (LOCALEDIR): Remove, now that we use the configmake module.
8539 * src/getargs.c: Include configmake.h.
8540 * src/main.c: Likewise.
8541 * src/output.c: Likewise.
8542 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
8543 not from $abs_top_builddir, since config.h moved.
8544
8545
8546 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
8547 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
8548
8549 * src/parse-gram.y (symbol_declaration): Don't put statements
8550 before declarations; it's not portable to C89.
8551 * src/scan-code.l (handle_action_at): Likewise.
8552
8553 * src/scan-code.l: Always initialize braces_level; the old code
8554 left it uninitialized and therefore had undefined behavior.
8555
8556 Don't attempt to redefine 'assert', since it runs afoul of
8557 systems where standard headers (mistakenly) include <assert.h>.
8558 Instead, define and use our own alternative, called 'aver'.
8559 * src/reader.c: Don't include assert.h, since we no longer
8560 use assert.
8561 * src/scan-code.l: Likewise.
8562 * src/system.h (assert): Remove, replacing with....
8563 (aver): New function, taking a bool arg. All uses changed.
8564 * src/tables.c (pack_vector): Ensure that aver arg is bool,
8565 not merely an integer.
8566
8567 2006-09-15 Bob Rossi <bob@brasko.net>
8568
8569 Add support for push parsing. Based on the original work of
8570 Odd Arild Olsen <oao@fibula.no>.
8571 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
8572 * data/c.m4 (YYPUSH): New.
8573 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
8574 * data/push.c: New file.
8575 * src/getargs.c (push_parser): New var.
8576 * src/getargs.h (push_parser): New declaration.
8577 * src/output.c (prepare): Add macro insertion of `push_flag'.
8578 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
8579 (prologue_declaration): Parse %push-parser.
8580 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
8581 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
8582 list of removed lines from the traces observed.
8583 (AT_CHECK_CALC_LALR): Added push parser tests.
8584
8585 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
8586
8587 * NEWS: Version 2.3a.
8588 * configure.ac (AC_INIT): Likewise.
8589
8590 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
8591 "#define YYSTYPE int" that caused "make maintainer-check" to fail
8592 due to header ordering dependencies. I don't know why the #define
8593 was there.
8594
8595 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
8596 runtime cost when YYDEBUG is not defined, and so that some tests
8597 that used to fail now work. Problem and initial suggestion by
8598 Paolo Bonzini.
8599 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
8600 * data/glr.cc (b4_parser_class_name):
8601 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
8602 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
8603 (yydebug_) [YYDEBUG]: New member.
8604 (yycdebug_): Now defined only if YYDEBUG.
8605 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
8606 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
8607 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
8608 if YYYDEBUG.
8609 (debug_stream, set_debug_stream, debug_level, set_debug_level):
8610 Define only if YYDEBUG.
8611 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
8612 set_debug_level.
8613 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
8614 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
8615 AT_CHECK_CALC_GLR_CC that are working now.
8616
8617 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
8618
8619 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
8620 We don't need them in glr.cc, and glr.c defines them.
8621 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
8622 assumes that defining it to anything is the same as defining
8623 it to 1. Problem reported by Paolo Bonzini.
8624
8625 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
8626
8627 * data/c.m4 (b4_null, b4_case): Define.
8628 * src/output.c (prepare_symbols): Use b4_null.
8629 (user_actions_output): Use b4_case.
8630
8631 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
8632
8633 * data/glr.c (b4_shared_declarations): Put start-header first,
8634 before any #includes that we generate, so that feature-test
8635 macros work. Problem reported by Michael Deutschmann in
8636 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
8637 * data/lalr1.cc: Likewise.
8638 * doc/bison.texinfo (Prologue): Document that feature-test macros
8639 should be defined before any Bison declarations.
8640 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
8641 that depend on location.hh after, not before, Bison decls, since
8642 we now include location.hh after the first user prologue.
8643
8644 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
8645 Sander Brandenburg in
8646 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
8647 Also, fix minor white space and comment issues.
8648 (Prologue): Mention that it's better to define feature-test macros
8649 before Bison declarations. Problem reported by Michael Deutschmann.
8650
8651 * README-cvs: Fix typo: "&" should be "&&". Problem reported
8652 by Jim Meyering.
8653 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
8654 This adjusts to recent gnulib changes.
8655
8656 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
8657
8658 Finish implementation of per-type %destructor/%printer. Discussed
8659 starting at
8660 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
8661 and
8662 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
8663 * NEWS (2.3+): Add a description of this feature to the default
8664 %destructor/%printer description.
8665 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
8666 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
8667 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
8668 list node contains a semantic type.
8669 * src/symtab.c, src/symtab.h: Extend with a table that associates
8670 semantic types with their %destructor's and %printer's.
8671 (semantic_type_from_uniqstr, semantic_type_get,
8672 semantic_type_destructor_set, semantic_type_printer_set): New functions
8673 composing the public interface of that table.
8674 (symbol_destructor_get, symbol_destructor_location_get,
8675 symbol_printer_get, symbol_printer_location_get): If there's no
8676 per-symbol %destructor/%printer, look up the per-type before trying
8677 the default.
8678 * tests/actions.at (Per-type %printer and %destructor): New test case.
8679 * tests/input.at (Default %printer and %destructor redeclared):
8680 Extend to check that multiple occurrences of %symbol-default in a
8681 single %destructor/%printer declaration is an error.
8682 (Per-type %printer and %destructor redeclared, Unused values with
8683 per-type %destructor): New test cases.
8684
8685 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
8686
8687 Require default %destructor/%printer to be declared using
8688 %symbol-default instead of an empty symbol list, and start working on
8689 new per-type %destructor/%printer. Discussed at
8690 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
8691 * NEWS (2.3+): Add %symbol-default to example.
8692 * bison.texinfo (Freeing Discarded Symbols): Likewise.
8693 (Table of Symbols): Add entry for %symbol-default.
8694 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
8695 (generic_symlist, generic_symlist_item): New nonterminals for creating
8696 a list in which each item is a symbol, semantic type, or
8697 %symbol-default.
8698 (grammar_declaration): Use generic_symlist in %destructor and %printer
8699 declarations instead of symbols.1 or an empty list.
8700 (symbol_declaration, precedence_declaration, symbols.1): Update actions
8701 for changes to symbol_list.
8702 * src/reader.c: Update for changes to symbol_list.
8703 * src/scan-code.l: Likewise.
8704 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
8705 * src/symlist.c, src/symlist.h: Extend such that a list node may
8706 represent a semantic type or a %symbol-default in addition to just an
8707 ordinary symbol. Add switched functions for setting %destructor's and
8708 %printer's.
8709 * tests/actions.at, tests/input.at: Add %symbol-default to all default
8710 %destructor/%printer declarations.
8711
8712 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
8713
8714 Whether the default %destructor/%printer applies to a particular symbol
8715 isn't a question of whether the user *declares* that symbol (in %token,
8716 for example). It's a question of whether the user by any means
8717 *defines* the symbol at all (by simply using a char token, for
8718 example). $end is defined by Bison whereas any other token with token
8719 number 0 is defined by the user. The error token is always defined by
8720 Bison regardless of whether the user declares it with %token, but we
8721 may one day let the user define error as a nonterminal instead.
8722 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
8723 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
8724 the meaning of "user-defined".
8725 * tests/actions.at (Default %printer and %destructor for user-declared
8726 end token): Rename to...
8727 (Default %printer and %destructor for user-defined end token): ...
8728 this.
8729
8730 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
8731 computation of whether to apply the default, don't maintain a list of
8732 every Bison-defined symbol. Instead, just check for a first character
8733 of '$', which a user symbol cannot have, and check for the error token.
8734
8735 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
8736
8737 Don't apply the default %destructor or %printer to the error token,
8738 $undefined, or $accept. This change fits the general rule that the
8739 default %destructor and %printer are only for user-declared symbols,
8740 and it solves several difficulties that are described in the new test
8741 cases listed below.
8742 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
8743 * tests/actions.at (Default %printer and %destructor are not for error
8744 or $undefined, Default %printer and %destructor are not for $accept):
8745 New test cases.
8746
8747 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
8748
8749 Allow %start after the first rule.
8750 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
8751 when parsing the first rule.
8752 (check_and_convert_grammar): Search for it here after all grammar
8753 declarations have been parsed. Skip midrules, which have dummy LHS
8754 nonterminals.
8755 * src/symtab.c (symbol_is_dummy): New function.
8756 * src/symtab.h (symbol_is_dummy): Declare it.
8757 * tests/input.at (%start after first rule): New test.
8758
8759 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
8760
8761 Redo some of the previous commit: add back the ability to use
8762 non-aliased/undeclared string literals since it might be useful to
8763 those declaring %token-table.
8764 * src/reader.c (check_and_convert_grammar): Undo changes in previous
8765 commit: don't worry about complaints from symbols_pack.
8766 * src/symtab.c (symbol_new, symbol_class_set,
8767 symbol_check_alias_consistency): Undo changes in previous commit: count
8768 each string literal as a new symbol and token, assign it a symbol
8769 number, and don't complain about non-aliased string literals.
8770 (symbols_pack): Since symbol_make_alias still does not decrement symbol
8771 and token counts but does still set aliased tokens to the same number,
8772 symbol_pack_processor now leaves empty slots in the symbols array.
8773 Remove those slots.
8774 * tests/regression.at (Undeclared string literal): Remove test case
8775 added in previous commit since non-aliased string literals are allowed
8776 again.
8777 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
8778 remove unnecessary string literal declarations.
8779 * tests/sets.at (Firsts): Likewise.
8780
8781 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
8782
8783 Don't allow an undeclared string literal, but allow a string literal to
8784 be used before its declaration.
8785 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
8786 symbols_pack complained.
8787 * src/symtab.c (symbol_new): Don't count a string literal as a new
8788 symbol.
8789 (symbol_class_set): Don't count a string literal as a new token, and
8790 don't assign it a symbol number since symbol_make_alias does that.
8791 (symbol_make_alias): It's not necessary to decrement the symbol and
8792 token counts anymore. Don't assume that an alias declaration occurs
8793 before any uses of the identifier or string, and thus don't assert that
8794 one of them has the highest symbol number so far.
8795 (symbol_check_alias_consistency): Complain if there's a string literal
8796 that wasn't declared as an alias.
8797 (symbols_pack): Bail if symbol_check_alias_consistency failed since
8798 symbol_pack asserts that every token has been assigned a symbol number
8799 although undeclared string literals have not.
8800 * tests/regression.at (String alias declared after use, Undeclared
8801 string literal): New test cases.
8802 (Characters Escapes, Web2c Actions): Declare string literals as
8803 aliases.
8804 * tests/sets.at (Firsts): Likewise.
8805
8806 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
8807
8808 In the grammar scanner, STRING_FINISH unclosed constructs and return
8809 them to the parser in order to improve error messages.
8810 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
8811 SC_BRACED_CODE, SC_PROLOGUE): Implement.
8812 * tests/input.at (Unclosed constructs): New test case.
8813 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
8814 seen.
8815
8816 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
8817 unused global.
8818
8819 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
8820
8821 Handle string aliases for character tokens correctly.
8822 * src/symtab.c (symbol_user_token_number_set): If the token has an
8823 alias, check and set its alias's user token number instead of its own,
8824 which is set to indicate the alias. Previously, every occurrence of
8825 the character token in the grammar overwrote that alias indicator with
8826 the character code.
8827 * tests/input.at (String aliases for character tokens): New test.
8828
8829 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
8830
8831 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
8832
8833 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
8834
8835 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
8836 to prevent failures when building on older platforms.
8837 Check for autopoint failure.
8838 Set XGETTEXT_OPTIONS to values that check for C format strings,
8839 so that translators are warned about them (this also helps
8840 prevent core dumps).
8841
8842 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
8843 function, since it simplifies our code a bit.
8844
8845 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
8846 rather than -W, so we don't get bogus warnings about sign comparisons.
8847 Add -Wpointer-arith, since that warning is useful (it reports code
8848 that does not conform to C89 and that some compilers reject).
8849 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
8850 since it's no longer needed.
8851
8852 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
8853
8854 Clean up scanners a bit.
8855 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
8856 definitions so gcc won't warn when obstack_for_string is unused.
8857 * src/scan-code.l: config.h and system.h are already #include'd by
8858 scan-code-c.c, so get rid of them here.
8859 * src/scan-gram.l: Likewise.
8860 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
8861 definitions rather than duplicating the rest of it.
8862 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
8863
8864 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
8865
8866 Suppress signed/unsigned comparison warnings for yycheck.
8867 * data/c.m4 (b4_safest_int_type): New macro.
8868 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
8869 a signed int type, cast it to b4_safest_int_type first.
8870 * data/yacc.c: Likewise.
8871 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
8872 also overwritten.
8873
8874 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
8875
8876 * doc/bison.texinfo: Fix some typos.
8877
8878 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
8879
8880 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
8881 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
8882
8883 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
8884 the latest gnulib does this a different way.
8885 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
8886 translation was patched, so stop omitting it.
8887
8888 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
8889
8890 Enable declaration of default %printer/%destructor. Make the parser
8891 use these for all user-declared grammar symbols for which the user does
8892 not declare a specific %printer/%destructor. Thus, the parser uses it
8893 for token 0 if the user declares it but not if Bison generates it as
8894 $end. Discussed starting at
8895 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
8896 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
8897 and
8898 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
8899 * NEWS (2.3+): Mention.
8900 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
8901 declare a %destructor for a mid-rule's semantic value. It's just
8902 impossible to declare one specific to it.
8903 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
8904 code. Describe default %destructor form.
8905 * src/parse-gram.y (grammar_declaration): Parse default
8906 %printer/%destructor declarations.
8907 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
8908 and symbol_destructor_location_get rather than accessing the destructor
8909 and destructor_location members of struct symbol.
8910 (symbol_printers_output): Likewise but for %printer's.
8911 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
8912 again.
8913 * src/symtab.c (default_destructor, default_destructor_location,
8914 default_printer, default_printer_location): New static global
8915 variables to record the default %destructor and %printer.
8916 (symbol_destructor_get, symbol_destructor_location_get,
8917 symbol_printer_get, symbol_printer_location_get): New functions to
8918 compute the appropriate %destructor and %printer for a symbol.
8919 (default_destructor_set, default_printer_set): New functions to set the
8920 default %destructor and %printer.
8921 * src/symtab.h: Prototype all those new functions.
8922 * tests/actions.at (Default %printer and %destructor): New test to
8923 check that the right %printer and %destructor are called, that they're
8924 not called for $end, and that $$ and @$ work correctly.
8925 (Default %printer and %destructor for user-declared end token): New
8926 test to check that the default %printer and %destructor are called for
8927 a user-declared end token.
8928 * tests/input.at (Default %printer and %destructor redeclared, Unused
8929 values with default %destructor): New tests to check related grammar
8930 warnings and errors.
8931
8932 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
8933
8934 Clean up handling of %destructor for the end token (token 0).
8935 Discussed starting at
8936 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
8937 and
8938 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
8939
8940 Make the skeletons consistent in how they pop the end token and invoke
8941 its %destructor.
8942 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
8943 state, which has token number 0, since this would invoke the
8944 %destructor for the end token.
8945 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
8946 until after shifting the end token, or else it won't be popped.
8947 * data/yacc.c (yyparse): Likewise.
8948
8949 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
8950 it's the end token. Upon termination, destroy an unshifted lookahead
8951 even when it's the end token.
8952 * data/lalr1.cc (yy::parser::parse): Likewise.
8953 * data/yacc.c (yyparse): Likewise.
8954
8955 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
8956 value warnings for the end token when the user gives the end token a
8957 %destructor.
8958
8959 * tests/actions.at (Printers and Destructors): Test all the above.
8960
8961 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
8962
8963 Update to latest gnulib and gettext versions.
8964 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
8965 Add fopen-safer.
8966 (gnulib_files): Add m4/warning.m4. Don't worry about files
8967 overwritten by autopoint.
8968 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
8969 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
8970 rejects them.
8971 Don't use autoreconf; instead, invoke autopoint etc. by hand,
8972 so that we can remove the intl files at a better time.
8973 (intl_files_to_remove): Remove aclocal.m4, since it gets
8974 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
8975 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
8976 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
8977 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
8978 Remove datarootdir hack; no longer needed.
8979 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
8980 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
8981 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
8982 strdup.h.
8983 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
8984 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
8985
8986 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
8987
8988 * bootstrap: Adjust to today's change to gnulib-tool by invoking
8989 it with --assume-autoconf='latest-stable'.
8990
8991 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
8992
8993 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
8994 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
8995 YYSTYPE' and `{'.
8996 * src/muscle_tab.h (muscle_grow): Replace the header comments with
8997 those from muscle_tab.c since the old ones are misleading.
8998
8999 2006-07-13 Akim Demaille <akim@epita.fr>
9000
9001 Support %define "KEY" {VALUE}.
9002 * src/scan-code.h, src/scan-code.l (translate_action)
9003 (translate_rule_action, translate_symbol_action, translate_code):
9004 Return char *, not const char *.
9005 * src/parse-gram.y (declaration): Rename as...
9006 (prologue_declaration): this.
9007 (string_content): Remove this nonterminal, use STRING.
9008 (braceless, content, content.opt): New nonterminal.
9009 Use them.
9010 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
9011 as value.
9012 * src/scan-gram.l (getargs.h): Don't include it.
9013
9014 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
9015
9016 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
9017 rather than a for-loop that declares a local bool variable. This
9018 should work around a compatibility problem with a Cray x1e C++
9019 compiler reported by Hung Nguyen in
9020 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
9021 The for-loop was introduced in the 2004-11-17 change but I don't
9022 know why it was needed.
9023
9024 2006-07-12 Akim Demaille <akim@epita.fr>
9025
9026 * data/c.m4: Comment changes.
9027
9028 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
9029
9030 * src/complain.c (error_message, ERROR_MESSAGE): New.
9031 To factor...
9032 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
9033 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
9034
9035 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9036
9037 * NEWS: Instead of %union, you can define and use your own union type
9038 YYSTYPE if your grammar contains at least one <type> tag.
9039 Your YYSTYPE need not be a macro; it can be a typedef.
9040 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
9041 (Union Decl, Decl Summary): Document this.
9042 * data/glr.c (YYSTYPE): Implement this.
9043 * data/glr.cc (YYSTYPE): Likewise.
9044 * data/lalr1.cc (YYSTYPE): Likewise.
9045 * data/yacc.c (YYSTYPE): Likewise.
9046 * src/output.c (prepare): Output tag_seen_flag.
9047 * src/parse-gram.y (declaration, grammar_declaration):
9048 Use 'union_seen' rather than 'typed' to determine whether
9049 %union has been seen, since grammars can now be typed without
9050 %union.
9051 (symbol_declaration, type.opt, symbol_def):
9052 Keep track of whether a tag has been seen.
9053 * src/reader.c (union_seen, tag_seen): New vars.
9054 (typed): remove.
9055 * src/reader.h (union_seen, tag_seen, typed): Likewise.
9056 * src/scan-code.l (untyped_var_seen): New variable.
9057 (handle_action_dollar): Adjust to above changes.
9058 (handle_action_dollar, handle_action_at):
9059 Improve overflow checking for outlandish numbers.
9060 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
9061 avoid new diagnostics generated by above changes.
9062 * tests/regression.at (YYSTYPE typedef): Add test to check
9063 for type tags without %union.
9064
9065 * src/symlist.c (symbol_list_length): Return int, not unsigned
9066 int, since callers expect int. This may need to get revisited
9067 once we have proper integer overflow checking.
9068
9069 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
9070 object is now static.
9071
9072 * src/getargs.c (flags_argmatch): Return void, not int,
9073 to pacify ./configure --enable-gcc-warnings.
9074
9075 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
9076 since last_string is already defined to FLEX_PREFIX (last_string).
9077
9078 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9079
9080 Implement --warnings/-W.
9081 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
9082 replaced by...
9083 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
9084 Adjust callers.
9085 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
9086 (warnings_args, warnings_types): New.
9087 (getargs, short_options, long_options): Accept -W/--warnings.
9088 Sort the options by alphabetical order, upper case letter right
9089 before its lower case.
9090
9091 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
9092
9093 Change %merge result type clash warnings to errors. Discussed at
9094 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
9095 * src/reader.c (record_merge_function_type): Use complain_at.
9096 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9097 declared later): Update test case results.
9098
9099 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9100
9101 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
9102 to be in alphabetical order.
9103 (trace_args): Spelling fixes.
9104
9105 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9106
9107 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
9108 so they don't collide with user-defined macros.
9109 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
9110 this was never guaranteed, and now that we're using gnulib stdint,
9111 which defines int_fast16_t to long int, the problem is exposed.
9112
9113 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
9114
9115 * data/c.m4 (b4_basename): Simplify a bit, since we don't
9116 need the full POSIX semantics (and weren't implementing them
9117 anyway).
9118
9119 Adjust to Autoconf 2.60 and today's gnulib.
9120 * bootstrap (gnulib_modules): Add stdint.
9121 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
9122 no longer copies it.
9123 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
9124 since stdint needs the former and wcwidth (which is now required
9125 by mbswidth) needs the latter.
9126 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
9127 work around a compatibility glitch between gettext 0.14.6 and
9128 Autoconf 2.60.
9129 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
9130 Do not check for uintptr_t, since new stdint module does the right
9131 thing.
9132 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
9133 Add stdint.h, stdint_.h, wcwidth.h.
9134 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
9135 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
9136 stdint.m4, wchar_t.m4, wcwidth.m4.
9137 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
9138 usual order for ../lib/*.h files.
9139 (file_name_split): Use last_component, not base_name, to adjust
9140 to gnulib changes.
9141 * src/parse-gram.h: Include <strverscmp.h> in the usual order
9142 for ../lib/*.h files.
9143 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
9144 Define unconditionally, since we now assume the stdint module.
9145 * src/scan-skel.l: Include <dirname.h>.
9146 (BASE_QPUTS): Use last_component, not base_name.
9147 * src/system.h: Include <unlocked-io.h> in the usual order
9148 for ../lib/*.h files. Include <stdint.h> unconditionally,
9149 since we now use the stdint module.
9150 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
9151 HAVE_UINTPTR_T, since we now use the stdint module.
9152 (base_name): Remove decl, since files now include <dirname.h>
9153 to get the decl.
9154
9155 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9156
9157 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
9158 New, default to 1.
9159 * data/yacc.c, data/glr.c, data/location.cc: Use them.
9160 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
9161 default.
9162 * tests/calc.at: Adjust.
9163
9164 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9165
9166 * data/c.m4 (b4_basename): New.
9167 (b4_syncline): Also output the location of its invocation (from
9168 the skeleton).
9169 (b4_user_action, b4_define_user_action, b4_user_actions)
9170 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
9171 (b4_user_stype): New.
9172 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
9173
9174 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9175
9176 In the grammar file, the first column is 1 not 0 on the first line as
9177 on every other line.
9178 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
9179 * tests/input.at (Torturing the Scanner): Update output.
9180
9181 * src/scan-gram.l (scanner_cursor): Declare it static.
9182
9183 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9184
9185 In warnings, say "previous declaration" rather than "first
9186 declaration".
9187 * src/symtab.c (redeclaration): Do that here.
9188 * src/reader.c (record_merge_function_type): In the case of a result
9189 type clash, report the previous declaration rather than the very first
9190 one in the grammar file.
9191 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9192 declared later): Add a third declaration to check this behavior.
9193 * tests/input.at (Incompatible Aliases): Update output.
9194
9195 2006-06-27 Akim Demaille <akim@epita.fr>
9196
9197 * doc/Doxyfile.in: New.
9198 * doc/Makefile.am: Use it.
9199 * src/lalr.h, src/symtab.h: Initial doxygenation.
9200
9201 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9202
9203 Don't miss %merge result type warnings just because the LHS types are
9204 declared after the %merge. This continues the effort of the previous
9205 patch.
9206 * src/reader.c (get_merge_function): Don't set the merger type yet.
9207 (record_merge_function_type): New function for setting the merger type
9208 and checking for clashes.
9209 (grammar_current_rule_merge_set): Set the location of the %merge for
9210 the current rule.
9211 (packgram): Invoke record_merge_function_type for each rule now that
9212 all symbol type declarations have been parsed.
9213 * src/reader.h (merger_list.type_declaration_location): New member
9214 storing the location of the first %merge from which the type for this
9215 merging function was derived.
9216 * src/symlist.h (symbol_list.merger_declaration_location): New member
9217 storing the location of a rule's %merge, if any.
9218 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9219 declared later): New test to catch the error fixed by the above patch.
9220
9221 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9222
9223 Get action warnings (grammar_rule_check) right even when symbol
9224 declarations appear after the rules. Discussed at
9225 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
9226 and
9227 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
9228 Don't mistake the type of $$ in a midrule to be that of its parent
9229 rule's $$.
9230 * src/reader.c (grammar_current_rule_end): Don't invoke
9231 grammar_rule_check yet since not all symbol declarations may have been
9232 parsed yet.
9233 (grammar_midrule_action): Likewise.
9234 Don't record whether the midrule's $$ has been used yet since actions
9235 haven't been translated yet.
9236 Record the midrule's parent rule and its RHS index within the parent
9237 rule.
9238 (grammar_current_rule_action_append): Don't translate the action yet
9239 since not all symbol declarations may have been parsed yet and, thus,
9240 warnings about types for $$, $n, @$, and @n can't be reported yet.
9241 (packgram): Translate the action and invoke grammar_rule_check now that
9242 all symbol declarations have been parsed.
9243 * src/scan-code.l (handle_action_dollar): Now that this is invoked
9244 after parsing the entire grammar file, the symbol list here in the case
9245 of a midrule is actually the midrule's empty RHS, so reference its
9246 parent rule's RHS where necessary.
9247 On the other hand, now that you can already know it's a midrule, you
9248 aren't forced to think $$ has the same type as its parent rule's $$.
9249 (handle_action_at): In the case of a midrule, reference the parent rule
9250 where necessary.
9251 * src/symlist.c (symbol_list_new): Initialize new midrule-related
9252 members.
9253 (symbol_list_length): Now that this is invoked after all rules have
9254 been parsed, a NULL symbol (rather than a NULL symbol list node)
9255 terminates a rule. symbol_list_print already does this correctly.
9256 * src/symlist.h (symbol_list.midrule_parent_rule,
9257 symbol_list.midrule_parent_rhs_index): New members so that midrules can
9258 remember their relationships with their parents.
9259 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
9260 fixed by the above patch.
9261 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
9262 implementing...
9263 (Unused values): ... this old test case and...
9264 (Unused values before symbol declarations): ... this new test case.
9265 This one is the same as `Unused values' except that all symbol
9266 declarations appear after the rules in order to catch the rest of the
9267 errors fixed by the above patch.
9268
9269 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9270
9271 More cleanup.
9272 * src/reader.c (current_rule): Declare it static since it's no longer
9273 used outside this file.
9274 (grammar_current_rule_action_append): Remove redundant arguments from
9275 translate_rule_action invocation.
9276 * src/reader.h (current_rule): Remove this unused extern.
9277 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
9278 * src/scan-code.l (translate_rule_action): Likewise.
9279
9280 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
9281
9282 Clean up yesterday's patch.
9283 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
9284 to...
9285 * src/reader.c (grammar_current_rule_action_append): ... here for
9286 consistency with grammar_current_rule_symbol_append.
9287 * tests/regression.at (Braced code in declaration in rules section):
9288 Make yyerror and yylex static as usual.
9289
9290 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
9291
9292 Fix bug that mistakes braced code in a declaration in the rules section
9293 to be a rule action. Mentioned at
9294 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
9295 * src/scan-gram.l: Move midrule action detection from the start of the
9296 scanning of any braced code to...
9297 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
9298 action. For readability, use $2 and @2 rather than the equivalent
9299 global variables.
9300 * tests/regression.at (Braced code in declaration in rules section):
9301 New test to catch the error fixed by the above patch.
9302
9303 Work on code readability some.
9304 * src/scan-code.l (current_rule): Get rid of this misleading and
9305 redundant declaration: it's actually extern'ed in reader.h.
9306 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
9307 translate_action): Add a rule argument and use it instead of the global
9308 current_rule.
9309 (translate_rule_action): This already receives current_rule through an
9310 argument, so pass it on to translate_action instead of assigning
9311 current_rule to current_rule.
9312 (translate_symbol_action, translate_code): Pass rule = NULL to
9313 translate_action.
9314
9315 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
9316
9317 Rename %before-definitions to %start-header and %after-definitions to
9318 %end-header. Don't use these declarations to separate pre-prologue
9319 blocks from post-prologue blocks. Add new order-independent
9320 declarations %before-header and %after-header as alternatives to the
9321 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
9322 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
9323 * NEWS (2.3+): Update for these changes.
9324 * data/glr.c (b4_before_definitions): Update to...
9325 (b4_start_header): ... this.
9326 (b4_after_definitions): Update to...
9327 (b4_end_header): ... this.
9328 * data/glr.cc: Likewise.
9329 * data/lalr1.cc: Likewise.
9330 * data/yacc.c: Likewise.
9331 * doc/bison.texinfo (The prologue): Update names, and replace remaining
9332 prologue blocks with %*-header declarations.
9333 (Calc++ Parser): Likewise.
9334 (Decl Summary): Update names.
9335 (Table of Symbols): Update description.
9336 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
9337 (PERCENT_END_HEADER): ... this.
9338 (PERCENT_BEFORE_DEFINITIONS): Update to...
9339 (PERCENT_START_HEADER): ... this.
9340 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
9341 (declaration): Update token names and m4 macro names.
9342 When parsing %end-header and %start-header, invoke translate_code
9343 before muscle_code_grow, and no longer set global booleans to remember
9344 whether these declarations have been seen.
9345 Parse new %after-header and %before-header.
9346 * src/reader.c (before_definitions, after_definitions): Remove.
9347 (prologue_augment): Accept a new bool argument to specify whether to
9348 augment the pre-prologue or post-prologue.
9349 * src/reader.h (before_definitions, after_definitions): Remove these
9350 extern's.
9351 (prologue_augment): Add new bool argument.
9352 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
9353 (PERCENT_END_HEADER): ... this.
9354 (PERCENT_BEFORE_DEFINITIONS): Update to...
9355 (PERCENT_START_HEADER): ... this.
9356 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
9357 * tests/actions.at (Printers and Destructors): Update names.
9358
9359 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
9360
9361 Add comparison operators for C++ location classes. Discussed at
9362 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
9363 * data/c++.m4 (b4_define_location_comparison): New boolean %define
9364 declaration indicating whether filename_type has an operator==. If
9365 filename_type is `std::string', it defaults to `1', `0' otherwise.
9366 * data/location.cc: Iff b4_define_location_comparison is `1', add
9367 operator== and operator!= for class position and for class location.
9368
9369 Some minor fixes.
9370 * src/scan-action.l: Remove unused file.
9371 * src/symtab.c (symbol_printer_set): Use printer_location not
9372 destructor_location.
9373 * src/symtab.h (struct symbol): Replace incorrect source comment for
9374 printer members.
9375 * tests/input.at (Incompatible Aliases): Update output with correct
9376 printer location.
9377
9378 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
9379
9380 Don't put the pre-prologue in the header file. For the yacc.c code
9381 file and the glr.c header and code files, move the pre-prologue before
9382 the token definitions. Add new %before-definitions and
9383 %after-definitions to declare code that will go in both the header file
9384 and code file. Discussed at
9385 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
9386 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
9387 and
9388 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
9389 * NEWS (2.3+): Describe these changes.
9390 * data/glr.c (b4_pre_prologue): Move from within to before...
9391 (b4_shared_declarations): ... this.
9392 Add new b4_before_definitions before b4_token_enums.
9393 Add new b4_after_definitions at the end.
9394 * data/glr.cc (b4_pre_prologue): Replace with...
9395 (b4_before_definitions): ... this in the header file.
9396 (b4_after_definitions): New near the end of the header file.
9397 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
9398 code file right before including the header file.
9399 (b4_before_definitions): New in the previous position of
9400 b4_pre_prologue in the header file.
9401 (b4_after_definitions): New near the end of the header file.
9402 * data/yacc.c: Clean up some m4 quoting especially in the header file.
9403 (b4_token_enums_defines): In the code file, move to right before
9404 YYSTYPE for consistency with the header file.
9405 (b4_before_definitions): New right before b4_token_enums_defines in
9406 both the header and code file.
9407 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
9408 header and code file.
9409 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
9410 of prologues for %union dependencies.
9411 (Decl Summary): In %defines description, mention the effect of
9412 %before-definitions and %after-definitions on the header file.
9413 (Calc++ Parser): Forward declare driver in a %before-definitions rather
9414 than in the pre-prologue so that make check succeeds.
9415 (Table of Symbols): Add entries for %before-definitions and
9416 %after-definitions.
9417 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
9418 %before-definitions.
9419 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
9420 (declaration): Parse those declarations and append to
9421 b4_before_definitions and b4_after_definitions, respectively.
9422 * src/reader.c (before_definitions, after_definitions): New bools to
9423 track whether those declarations have been seen.
9424 (prologue_augment): Add to the post-prologue if %union,
9425 %before-definitions, or %after-definitions has been seen.
9426 * src/reader.h (before_definitions, after_definitions): New extern's.
9427 * src/scan-gram.l: Scan the new declarations.
9428 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
9429 prologue block in a %before-definitions or a %after-definitions based
9430 on whether the %union is declared.
9431 * tests/regression.at (Early token definitions with --yacc, Early token
9432 definitions without --yacc): Move tests for token definitions into the
9433 post-prologue since token names are no longer defined in the
9434 pre-prologue.
9435
9436 2006-06-20 Akim Demaille <akim@epita.fr>
9437
9438 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
9439 (symbol_get): Use it.
9440 * src/parse-gram.y: Use it.
9441
9442 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
9443
9444 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
9445 build succeeds when configured with --enable-gcc-warnings.
9446
9447 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9448
9449 * src/parse-gram.y (char_name): New function.
9450 (CHAR, STRING, string_content): For %printer, properly escape.
9451 (ID): Prefer fputs to fprintf.
9452 (id): Reindent to be consistent with other rules.
9453 Properly quote char.
9454
9455 The Translation Project changed its way of publishing translations
9456 to maintainers. I haven't received any responses to my request
9457 for supporting the old way, or for documenting the new way. I
9458 have modified 'bootstrap' to use screen scraping
9459 (in this case, HTML scraping). This is unreliable and inelegant,
9460 but I don't see any better way. Yuck.
9461 * bootstrap (TP_URL, WGET_COMMAND): New vars.
9462 (get_translations): New function, which uses HTML scraping to
9463 deduce locations of latest translations.
9464 Use this function to grab both bison and bison-runtime .po files.
9465 Don't bother priming the pump for the runtime-po domain any more,
9466 as it's now translated better than bison is.
9467
9468 2006-06-19 Akim Demaille <akim@epita.fr>
9469
9470 * src/scan-gram.l: No longer "parse" things after `%union' until
9471 `{'. Rather, return a single "%union" token.
9472 No longer make symbols: return strings, and leave the conversion
9473 to symbols to the parser.
9474 (SC_PRE_CODE, token_type): Remove.
9475 * src/parse-gram.y (%union): New field `character'.
9476 Sort tokens.
9477 (CHAR): New token.
9478 (ID, ID_COLON): Now that the scanner no longer makes them
9479 identifiers, adjust all uses to invoke symbol_get.
9480 (id_colon): New, wraps the conversion from string to symbol.
9481 (%union): Accept a possible union_name.
9482 (symbol): Now can be a char.
9483 * data/c.m4 (b4_union_name): Leave a default value.
9484 * data/glr.c, data/yacc.c: Use it.
9485
9486 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
9487
9488 For associating token numbers with token names for "yacc.c", don't use
9489 #define statements unless `--yacc' is specified; always use enum
9490 yytokentype. Most important discussions start at:
9491 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
9492 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
9493 and
9494 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
9495 * NEWS (2.3+): Mention.
9496 * data/c.m4 (b4_yacc_if): New.
9497 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
9498 token #define's.
9499 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
9500 on token name definitions.
9501 * src/getargs.c (usage): Capitalize `Yacc' in English.
9502 * src/output.c (prepare): Define b4_yacc_flag.
9503 * tests/regression.at (Early token definitions): Test that tokens names
9504 are defined before the pre-prologue not just before the post-prologue.
9505 Remove this test case and copy to...
9506 (Early token definitions with --yacc): ... this to test #define's.
9507 (Early token definitions without --yacc): ... and this to test enums.
9508
9509 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
9510
9511 * NEWS: Reword the post-2.3 change to not be so optimistic about
9512 removing the old "look-ahead" spelling.
9513 Update previous look-ahead/lookahead change reports.
9514 * REFERENCES: look-ahead -> lookahead (since that's
9515 what he actually wrote).
9516 * doc/refcard.tex: look ahead -> lookahead,
9517 look-ahead -> lookahead
9518
9519 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
9520
9521 For consistency, use `lookahead' instead of `look-ahead' or
9522 `look_ahead'. Discussed starting at
9523 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
9524 and then at
9525 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

9591
9592 2006-06-08 Joel E. Denny <jdenny@ces.clemson.edu>
9593
9594 * src/flex-scanner.h (yytext): Remove stray `*/' in #define.
9595
9596 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9597
9598 * TODO: Add request from Nelson H. F. Beebe to be able to install
9599 Bison without installing the yacc script.
9600
9601 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
9602
9603 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
9604 and yytext if they're already #define'd.
9605 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
9606 * src/scan-code-c.c: ... here.
9607 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
9608 <config.h>.
9609
9610 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
9611
9612 Get Bison to build again when configured with --enable-gcc-warnings.
9613 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
9614 missing #include's.
9615 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
9616 loc argument as it shadows a global.
9617 * src/scan-gram.l: Remove stray comma that prevents boundary_set
9618 invocation.
9619
9620 * src/.cvsignore: Add scan-code.c.
9621
9622 2006-06-07 Akim Demaille <akim@epita.fr>
9623
9624 * src/scan-gram.l: Move the "add a trailing ; to actions" code
9625 to...
9626 * src/scan-code.l: here.
9627 * tests/input.at (Torturing the Scanner): Fix another location
9628 error.
9629
9630 2006-06-07 Akim Demaille <akim@epita.fr>
9631
9632 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
9633
9634 2006-06-06 Akim Demaille <akim@epita.fr>
9635
9636 Extract the parsing of user actions from the grammar scanner.
9637 As a consequence, the relation between the grammar scanner and
9638 parser is much simpler. We can also split "composite tokens" back
9639 into simple tokens.
9640 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
9641 * src/scan-gram.l (add_column_width, adjust_location): Move to and
9642 rename as...
9643 * src/location.h, src/location.c (add_column_width)
9644 (location_compute): these.
9645 Fix the column count: the initial column is 0.
9646 (location_print): Be robust to ending column being 0.
9647 * src/location.h (boundary_set): New.
9648 * src/main.c: Adjust to scanner_free being renamed as
9649 gram_scanner_free.
9650 * src/output.c: Include scan-code.h.
9651 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
9652 Use boundary_set.
9653 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
9654 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
9655 which is now, again, a separate token.
9656 Adjust all dependencies.
9657 Whereever actions with $ and @ are used, use translate_code.
9658 (action): Remove this nonterminal which is now useless.
9659 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
9660 (grammar_current_rule_action_append): Use translate_code.
9661 (packgram): Bound check ruleno, itemno, and rule_length.
9662 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
9663 (last_string, last_braced_code_loc, max_left_semantic_context)
9664 (scanner_initialize, scanner_free, scanner_last_string_free)
9665 (gram_out, gram_lineno, YY_DECL_): Move to...
9666 * src/scan-gram.h: this new file.
9667 (YY_DECL): Rename as...
9668 (GRAM_DECL): this.
9669 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
9670 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9671 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9672 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9673 Move these declarations, and...
9674 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
9675 these to...
9676 * src/flex-scanner.h: this new file.
9677 * src/scan-gram.l (rule_length, rule_length_overflow)
9678 (increment_rule_length): Remove.
9679 (last_braced_code_loc): Rename as...
9680 (gram_last_braced_code_loc): this.
9681 Adjust to the changes of the parser.
9682 Move all the handling of $ and @ into...
9683 * src/scan-code.l: here.
9684 * src/scan-gram.l (handle_dollar, handle_at): Remove.
9685 (handle_action_dollar, handle_action_at): Move to...
9686 * src/scan-code.l: here.
9687 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
9688 scan-code.h, scan-code-c.c, scan-gram.h.
9689 (EXTRA_bison_SOURCES): Add scan-code.l.
9690 (BUILT_SOURCES): Add scan-code.c.
9691 (yacc): Be robust to white spaces.
9692
9693 * tests/conflicts.at, tests/input.at, tests/reduce.at,
9694 * tests/regression.at: Adjust the column numbers.
9695 * tests/regression.at: Adjust the error message.
9696
9697 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
9698
9699 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
9700 Use Akim's wording from
9701 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
9702
9703 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
9704
9705 Between Bison releases, manually append `+' to the previous Bison
9706 release number, and use that as a signal to automatically print the
9707 ChangeLog's CVS Id keyword from --version. Discussed starting at
9708 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
9709 * ChangeLog: Add Id header.
9710 * configure.ac (AC_INIT): Append `+' to `2.3'.
9711 * src/.cvsignore: Add revision.c.
9712 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
9713 (BUILT_SOURCES): Add revision.c.
9714 (revision.c): New target rule. This file defines a new global variable
9715 named revision. It initializes it with either the Id from ChangeLog
9716 or, if VERSION doesn't contain `+', with the empty string.
9717 * src/getargs.c (version): Print the value of revision.
9718 * src/revision.h: Extern revision.
9719
9720 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9721
9722 * NEWS: Version 2.3.
9723 * configure.ac (AC_INIT): Likewise.
9724
9725 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9726
9727 * data/glr.c (YYRECOVERING): Define to be a function-like macro
9728 with no arguments, not as an object-like macro. This is for
9729 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
9730 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
9731 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
9732 Document this.
9733
9734 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
9735
9736 * src/getargs.c (usage): Back out yesterday's modification of the
9737 --help output so that we don't have to wait for translation before
9738 releasing 2.3.
9739
9740 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9741
9742 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
9743 Problem reported by Akim Demaille.
9744
9745 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
9746
9747 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
9748
9749 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9750
9751 * data/yacc.c (yy_reduce_print): Omit trailing white space in
9752 generated source code. Problem reported by Frans Englich in
9753 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
9754
9755 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
9756
9757 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
9758 shell, not within 'make', so that 'make' by an ordinary builder
9759 (using GNU make) does not worry about configuring gzip. This also
9760 works around a bug reported independently by Keith Thompson and by
9761 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
9762 stderr rather than stdout, messing up the build logs.
9763
9764 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
9765
9766 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
9767 to make sure that YYID will never be unused. This fixes a 'make
9768 maintainer-check' failure caused by the recent changes to the 'Trivial
9769 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
9770 not used.
9771 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
9772
9773 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
9774
9775 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
9776 state before an empty RHS is always resolved here. Only the location
9777 of that state is guaranteed to be resolved, and that's enough. This
9778 fixes the remaining bug reported by Derek M. Jones in
9779 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
9780 * tests/glr-regression.at (Uninitialized location when reporting
9781 ambiguity): Test the above case.
9782 Also, the embedded comments in this test case claim it checks the case
9783 of an empty RHS that has inherited the initial location. However, the
9784 corresponding LHS was already resolved, so yyresolveLocations didn't
9785 actually have reason to modify it. Fix this by forcing
9786 nondeterministic operation at the beginning of the parse.
9787
9788 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9789
9790 * data/c.m4 (b4_yy_symbol_print_generate):
9791 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
9792 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
9793 of the bugs reported today by Derek M Jones in
9794 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
9795 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
9796 defined to be a type name without parens or brackets.
9797 (Location Type): Similarly for YYLTYPE.
9798 * tests/regression.at (Trivial grammars): Put in a test for this
9799 bug that will be caught by 'make maintainer-check' (though not,
9800 alas, by 'make check' unless your compiler is picky).
9801
9802 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9803
9804 * NEWS: Version 2.2.
9805 * configure.ac (AC_INIT): Likewise.
9806
9807 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
9808
9809 * data/glr.c (yyreportTree): Make room in yystates for the state
9810 preceding the RHS. This fixes the segmentation fault reported by Derek
9811 M. Jones in
9812 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
9813 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
9814 to the user. Reported for yyreportTree by Derek M. Jones later in the
9815 same thread.
9816 * THANKS: Add Derek M. Jones.
9817 Update my email address.
9818 Fix typo in Steve Murphy's name.
9819
9820 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9821
9822 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
9823 checking against YYLAST that caused the parser to miss a potential
9824 alternative in its diagnostic.
9825 Problem reported by Maria Jose Moron Fernandez in
9826 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
9827 * data/lalr1.cc (yysyntax_error_): Likewise.
9828 * data/yacc.c (yysyntax_error): Likewise.
9829 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
9830 tokens, in case we run into an older C compiler.
9831 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
9832 Use them to check for the off-by-one error fixed above.
9833
9834 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
9835 YYSIZE_T, not size_t.
9836 * tests/regression.at (Trivial grammars): New test, to catch
9837 the error fixed by the above patch.
9838
9839 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9840
9841 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
9842 scheme.
9843 Reported by Steve Murphy.
9844
9845 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9846
9847 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
9848 * data/glr.cc: b4_location_flag is now b4_locations_flag.
9849
9850 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9851
9852 Implement --trace=m4.
9853 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
9854 * src/output.c (output_skeleton): When set, pass -dV to m4.
9855
9856 Factor the handling of flags in m4.
9857 * src/output.c (prepare): Rename the muscle names debug, defines,
9858 error_verbose to debug_flag, defines_flag, error_verbose_flag.
9859 * data/c.m4: Adjust.
9860 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
9861 Use b4_define_flag_if to define other b4_FLAG_if macros.
9862 (b4_location_if): As a consequence, rename as...
9863 (b4_locations_if): this, for consistency.
9864 Adjust all the skeletons.
9865
9866 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9867
9868 * etc/bench.pm: Shorten bench names.

9870 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9871
9872 * src/output.h, src/output.c (error_verbose): Move to...
9873 * src/getargs.h, src/getargs.c: here.
9874 Sort the flags.
9875 Adjust dependencies.
9876
9877 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9878
9879 * data/c.m4 (b4_copyright): Put the special exception for Bison
9880 skeletons here, so we don't have to put it in each skeleton. All
9881 uses changed. Suggested by Akim Demaille. Also, wrap the
9882 copyright notice, in case it is longer than 80 columns. Replace
9883 comma by newline after title.
9884
9885 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9886
9887 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
9888 incompatibility, not a bug. Mention that it wasn't fixed as of
9889 flex 2.5.33.
9890
9891 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9892
9893 * examples/extexi: Enforce the precedence of concatenation over
9894 >>.
9895 Reported by Tommy Nordgren.
9896
9897 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9898
9899 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
9900 with the member "token".
9901 Reported by Martin Nylin.
9902
9903 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
9904
9905 * data/glr.c: Switch to Bison 2.2 special-exception language in
9906 the copyright notice. Use more-regular format for titles and
9907 copyright notices.
9908 * data/glr.cc: Likewise.
9909 * data/location.cc: Likewise.
9910 * data/yacc.cc: Likewise.
9911 * doc/bison.texinfo (Conditions): Document this.
9912 * NEWS: likewise. Upgrade version to 2.2.
9913
9914 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
9915
9916 * data/glr.cc: Remove dead code.
9917
9918 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9919
9920 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
9921 that variable and the line breaks the bootstrap. Problem reported
9922 by Juan M. Guerrero.
9923
9924 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
9925

9928 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
9929
9930 * etc/README, etc/bench.pl: New.
9931
9932 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
9933
9934 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
9935 rule.
9936 Reported by Mickael Labau.
9937 * tests/input.at (Torturing the Scanner): Test it.
9938
9939 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
9940
9941 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
9942 Problem reported by Bob Rossi.
9943
9944 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
9945
9946 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
9947 and didn't really work.
9948 For the index, use @ifnotinfo, not @iftex.
9949 Minor cleanups of spacing and terminology.
9950
9951 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
9952
9953 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
9954 of AT_NAME_PREFIX when %name-prefix is not used.
9955
9956 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
9957
9958 Apply --prefix to C++ skeletons too: they change the namespace.
9959 The test suite already exercize these cases.
9960 * data/c++.m4 (b4_namespace): New.
9961 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
9962 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
9963 * data/yacc.c, data/glr.c: Remove a useless `[]'.
9964 * doc/bison.texinfo: Document it.
9965 (Option Cross Key): Use @multitable in all formats. It looks
9966 nicer, even in TeX outputs.
9967 (Rules): Use the same code whatever the output type is.
9968 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
9969 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
9970 * tests/calc.at: Use it, instead of hard coding `yy'.

9978 * doc/FAQ: Remove, merged into...

9980 * doc/Makefile.am (EXTRA_DIST): Adjust.
9981
9982 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
9983
9984 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
9985 even if empty.

9989 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
9990
9991 Fix two nits reported by twlevo, plus one more that I discovered.
9992
9993 * src/assoc.h (assoc_to_string): Give a name to the arg, as
9994 this is the usual Bison style.
9995 * src/location.h (location_print): Likewise.
9996
9997 * src/reader.h (token_name): Likewise.
9998
9999 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
10000
10001 Fix some nits reported by twlevo.
10002 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
10003 and "POSIX". Use more-modern syntax for URLs. Mention C++
10004 and ask for Java. Don't hardwire OS version numbers. Add
10005 copyright notice.
10006 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
10007 * src/conflicts.c (solved_conflicts_obstack): Now static.
10008
10009 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
10010
10011 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
10012 page. Say "you can use it" not "you may use it" as on the web page;
10013 we're describing capabilities not granting permission.
10014
10015 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
10016
10017 * data/glr.c (yyresolveLocations): Rename local variables to avoid
10018 shadowing warnings. Use usual patter for iterating through RHS.
10019 * tests/glr-regression.at
10020 (Uninitialized location when reporting ambiguity):
10021 Modify yylex so that it uses its argument, rather than trying
10022 to rely on ARGSUSED (which doesn't work for gcc with warnings).
10023 const char -> char const.
10024
10025 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
10026 Don't use tabs inside commands; it messes up 'ps'.
10027 Problem reported by twlevo.
10028
10029 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
10030
10031 * tests/glr-regression.at (Uninitialized location when reporting
10032 ambiguity): New test case.
10033 * data/glr.c (yyresolveLocations): New function, which uses
10034 YYLLOC_DEFAULT.
10035 (yyresolveValue): Invoke yyresolveLocations before reporting an
10036 ambiguity.
10037 * doc/bison.texinfo (Default Action for Locations): Note
10038 YYLLOC_DEFAULT's usage for ambiguity locations.
10039 (GLR Semantic Actions): Cross-reference those notes.
10040
10041 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
10042
10043 * tests/glr-regression.at (Leaked semantic values when reporting
10044 ambiguity): Remove unnecessary union and type declarations.
10045 (Leaked lookahead after nondeterministic parse syntax error): New test
10046 case.
10047 * data/glr.c (yyparse): Check for zero stacks remaining before
10048 attempting to shift the lookahead so that you don't lose it.
10049
10050 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10051
10052 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
10053 * tests/glr-regression.at (Leaked semantic values when reporting
10054 ambiguity): New test case.
10055 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
10056 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
10057 now unnecessary yystackp parameter.
10058 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
10059 destructors can be called.
10060
10061 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
10062 in existing testcases.
10063
10064 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10065
10066 Don't leak semantic values for parent RHS when a user action cuts the
10067 parser, and clean up related code a bit.
10068 * tests/glr-regression.at (Leaked merged semantic value if user action
10069 cuts parse): Rename to...
10070 (Leaked semantic values if user action cuts parse): ... this. Add check
10071 for leaked parent RHS values.
10072 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
10073 between an unresolved state (non-empty chain of semantic options) and
10074 an incomplete one (signaled by an empty chain).
10075 (yyresolveStates): Document the interface. Move all manipulation of a
10076 successfully or unsuccessfully resolved yyGLRState to...
10077 (yyresolveValue): ... here so that yyresolveValue always leaves a
10078 yyGLRState with consistent data and thus is easier to understand.
10079 Remove the yyvalp and yylocp parameters since they are always just
10080 taken from the yys parameter. When reporting a discarded merged value
10081 in debugging output, note that it is incompletely merged. Document the
10082 interface.
10083 (yyresolveAction): If resolving any of the RHS states fails, destroy
10084 them all rather than leaking them. Thus, as long as user actions are
10085 written to clean up the RHS correctly, yyresolveAction always cleans up
10086 the RHS of a semantic option. Document the interface.
10087
10088 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
10089
10090 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
10091 led to a segmentation fault in GNU Pascal. Problem reported
10092 by Waldek Hebisch.
10093
10094 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
10095
10096 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
10097 mid-rule action inside a nonterminal symbol in order to declare a
10098 destructor for its semantic value.
10099
10100 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>

10104 __cplusplus && ! defined _STDLIB_H && !
10105 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
10106 defined free))]: Include <stdlib.h> rather than rolling our own
10107 declarations of malloc and free, to avoid problems with
10108 incompatible declarations (using 'throw') C++'s stdlib.h. This
10109 should fix Debian bug 340012

10139 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
10140 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
10141 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
10142 messes up because C++ code is compiled in 32-bit mode but linked
10143 in 64-bit mode.

10150 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
10151
10152 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
10153 nodist_PROGRAMS, since we don't need to actually compile the
10154 example if we're just doing a plain 'make'. This avoids bothering
10155 the installer unnecessarily about problems due to weird C++
10156 compilers.

10159
10160 More portability fixes for problems summarized by Nelson H. F. Beebe.
10161
10162 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
10163 than #include "...", and compile with -I'.'. The old method was
10164 not portable, according to Posix and the C standard, and it does
10165 not work with Sun C 5.7, where previous #line directives affect
10166 the working directory used in later #include "..." directives.

10184 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
10185 that '#include <string>' works.
10186
10187 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
10188 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
10189 "warning: sorry: semantics of inline function static data `const
10190 unsigned char translate_table[262]' are wrong (you'll wind up with
10191 multiple copies)".
10192
10193 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
10194 or, xor to not_, and_, or_, and xor_, respectively. This works
10195 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
10196 random system header somewhere that includes the equivalent of
10197 <iso646.h>.
10198
10199 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
10200 -E" works; it apparently doesn't work with PathScale EKO Compiler

10204
10205 During deterministic GLR operation, user actions should be able to
10206 influence the parse by changing yychar. To make this easier to fix and
10207 to make glr.c easier to evolve in general, don't maintain yytoken in
10208 parallel with yychar; just compute yytoken when needed.
10209 * tests/glr-regression.at (Incorrect lookahead during deterministic
10210 GLR): Check that setting yychar in a user action has the intended
10211 effect.
10212 * data/glr.c (yyGLRStack): Remove yytokenp member.
10213 (yyclearin): Don't set *yytokenp.
10214 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
10215 yychar rather than *yytokenp to determine the current lookahead.
10216 Compute yytoken locally when needed.
10217 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
10218 point to.
10219
10220 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
10221 after `--report' documentation.
10222

10225 * src/parse-gram.y (grammar_declaration): Location of printer
10226 symbol is @1, not list->location. Bug reported by twlevo.
10227 * tests/input.at (Incompatible Aliases): Adjust to above change.
10228
10229 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
10230
10231 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
10232 all the test at once. This makes the output easier to read in the
10233 normal case.
10234
10235 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
10236 got from <http://bro-ids.org/download.html>. The bug is that
10237 when two actions appeared in succession, the second one was
10238 scanned before the first one was added to the grammar rule
10239 as a midrule action. Bison then output the incorrect warning
10240 "parse.y:905.17-906.36: warning: unused value: $3".
10241 * src/parse-gram.y (BRACED_CODE, action): These are no longer
10242 associated with a value.
10243 (rhs): Don't invoke grammar_current_rule_action_append.
10244 (action): Invoke it here instead.
10245 * src/reader.c (grammar_midrule_action): Now extern.
10246 (grammar_current_rule_action_append): Don't invoke
10247 grammar_midrule_action; that is now the scanner's job.
10248 * src/reader.h (last_string, last_braced_code_loc):
10249 (grammar_midrule_action): New decls.
10250 * src/scan-gram.l (last_string): Now extern, sigh.
10251 (last_braced_code_loc): New extern variable.
10252 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
10253 rule already has an action.

10259
10260 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
10261 All used changed. Check whether the symbol has a destructor,
10262 not whether it is typed.
10263 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
10264 that the values are still reported as unused. All line numbers
10265 adjusted.
10266

10301 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
10302 Move these decls to scan-skel.l, since they don't need to be
10303 visible elsewhere.
10304 * src/scan-skel.l: Accept the above decls.
10305 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
10306 is used.

10309
10310 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
10311 since we don't want to insist on a version number at the start
10312 of the changelog every time.
10313 * Makefile.maint: Sync from coreutils a bit better.

10359 * lib/vbitset.c: Likewise.
10360 * tests/local.at: Likewise.
10361 * src/scan-gram.l: Don't include verify.h, since system.h does
10362 that for us.
10363 * .x-sc_require_config_h: New file.
10364 * .x-sc_unmarked_diagnostics: New file.
10365
10366 2006-01-20 Paul Eggert <eggert@cs.ucla.edu>

10383 value, to catch invalid enum values as well.
10384 * src/lalr.c (set_goto_map, map_goto):
10385 Prefer "assert (FOO);" to "if (!FOO) abort ();".

10403 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
10404
10405 Fix some porting glitches found by Nelson H. F. Beebe.
10406 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
10407 compilers that don't understand that abort () does not return.
10408 * src/state.c (transitions_to): Likewise.
10409 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check

10417
10418 Minor fixups to get 'make maintainer-check' to work.
10419 * configure.ac: Don't use -Wnested-externs, as it's incompatible
10420 with the new verify.h implementation.
10421 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
10422 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
10423 * data/yacc.c (YYUSE): Likewise.
10424 * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).

10426 * src/parse-gram.y (declaration): Don't pass a string constant
10427 to a function that expects char *, since GCC might complain
10428 about the constant value.
10429 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
10430 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval

10436 (Incorrect lookahead during deterministic GLR):
10437 (Incorrect lookahead during nondeterministic GLR):

10439
10440 2006-01-19 Akim Demaille <akim@epita.fr>
10441
10442 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial

10451
10452 * Makefile.maint: Merge with coreutils Makefile.maint.
10453 (CVS_LIST): Use build-aux version if available.
10454 (VERSION_REGEXP): New macro.
10455 (syntax-check-rules): Add sc_no_if_have_config_h,

10466 (announcement): Add --gpg-key-ID.
10467
10468 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
10469 with "file system".
10470
10471 Avoid undefined behavior that addressed just before the start of an
10472 array. Problem reported by twlevo.
10473 * src/reader.c (packgram): Prepend a new sentinel before ritem.
10474 * src/lalr.c (build_relations): Rely on new sentinel.
10475 * src/gram.c (gram_free): Adjust to new sentinel.
10476
10477 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
10478
10479 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
10480 yylookaheadNeeds. All uses updated.
10481 (yysplitStack): Rename local yynewLookaheadStatuses to
10482 yynewLookaheadNeeds.
10483 * data/glr-regression.at (Incorrect lookahead during nondeterministic
10484 GLR): In comments, change `lookahead status' to `lookahead need'.
10485
10486 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10487
10488 * data/glr.c (yysplitStack): A little stylistic rewrite.

10493
10494 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
10495
10496 * doc/bison.texinfo: Fix some typos.
10497 (GLR Semantic Actions): New subsection discussing special
10498 considerations because GLR semantic actions might be deferred.
10499 (Actions): Mention look-ahead usage of yylval.
10500 (Actions and Locations): Mention look-ahead usage of yylloc.
10501 (Special Features for Use in Actions): Add YYEOF entry and mention it
10502 in the yychar entry.
10503 In the yychar entry, remove mention of the local yychar case (pure
10504 parser) since this is irrelevant information when writing semantic
10505 actions and since it's already discussed in `Table of Symbols' where
10506 yychar is otherwise described as an external variable.
10507 In the yychar entry, don't call it the `current' look-ahead since it
10508 isn't when semantic actions are deferred.
10509 In the yychar and yyclearin entries, add note about deferred semantic
10510 actions.
10511 Add yylloc and yylval entries discussing look-ahead usage.
10512 (Look-Ahead Tokens): When discussing yychar, don't call it the
10513 `current' look-ahead, and do mention yylval and yylloc.
10514 (Error Recovery): Cross-reference `Action Features' when mentioning
10515 yyclearin.
10516 (Table of Symbols): In the yychar entry, don't call it the `current'
10517 look-ahead.
10518 In the yylloc and yylval entries, mention look-ahead usage.
10519
10520 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
10521
10522 * tests/glr-regression.at: Update copyright year to 2006.
10523
10524 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10525
10526 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
10527 use during nondeterministic operation to track which stacks have
10528 actually needed the current lookahead.
10529 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
10530 Allocate, deallocate, resize, and otherwise shuffle space for
10531 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
10532 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
10533 appropriately during nondeterministic operation.
10534 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
10535 members to store the current lookahead to be used by the deferred
10536 user action.
10537 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
10538 from which the RHS is taken. Set the lookahead members of the new
10539 yySemanticOption according to the lookahead status for stack yyk.
10540 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
10541 yyaddDeferredAction.
10542 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
10543 members of yySemanticOption before invoking yyuserAction, and then set
10544 them back to their current values afterward.
10545 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
10546 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
10547 * tests/glr-regression.at: Remove `.' from the ends of recent test case
10548 titles for consistency.
10549 (Leaked merged semantic value if user action cuts parse): In order to
10550 suppress lint warnings, use arguments in merge function, and assign
10551 char value < 128 in main.
10552 (Incorrect lookahead during deterministic GLR): New test case.
10553 (Incorrect lookahead during nondeterministic GLR): New test case.
10554
10555 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10556
10557 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
10558 !yyvaluep as signal that no semantic value is available to print.
10559 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
10560 to print a semantic value.
10561
10562 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10563
10564 * tests/glr-regression.at: For consistency with my newer test cases,
10565 don't thank myself.
10566
10567 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
10568
10569 * data/glr.c (yyresolveValue): When merging semantic options, if at
10570 least one user action succeeds but a later one cuts the parse, then
10571 destroy the semantic value before returning rather than leaking it.
10572 (yyresolveStates): If a user action cuts the parse and thus
10573 yyresolveValue fails, ignore the (unset) semantic value rather than
10574 corrupting the yyGLRState, and empty the semantic options list since
10575 the user actions should have called all necessary destructors.
10576 Simplify code with YYCHK.
10577 * tests/glr-regression.at (Corrupted semantic options if user action
10578 cuts parse): New test case.
10579 (Undesirable destructors if user action cuts parse): New test case.
10580 Before applying any of this patch, this test case never actually failed
10581 for me... but only because the corrupted semantic options usually
10582 masked this bug.
10583 (Leaked merged semantic value if user action cuts parse): New test
10584 case.
10585
10586 2006-01-05 Akim Demaille <akim@epita.fr>

10591
10592 * data/c.m4 (b4_c_modern): New macro, with a new provision for
10593 _MSC_VER. Problem reported by Cenzato Marco.
10594 (b4_c_function_def): Use it.
10595 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
10596 b4_c_modern.
10597 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
10598 than rolling our own.
10599
10600 2006-01-04 Akim Demaille <akim@epita.fr>
10601
10602 Also warn about non-used mid-rule values.

10604 member.
10605 (symbol_list_new): Adjust.
10606 * src/reader.c (symbol_typed_p): New.
10607 (grammar_rule_check): Use it.
10608 (grammar_midrule_action): Bind a mid-rule LHS to its rule.
10609 Check its rule.

10613
10614 2006-01-04 Akim Demaille <akim@epita.fr>
10615
10616 * src/reader.c (grammar_midrule_action): If $$ is set in a
10617 mid-rule, move the `used' bit to its lhs.
10618 * tests/input.at (Unused values): New.
10619 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
10620
10621 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
10622
10623 * doc/bison.texinfo (Bison Options): Say more accurately what
10624 --yacc does.
10625 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
10626 about declarations in the grammar when in Yacc mode, as POSIX does
10627 not require a diagnostic when the grammar uses extensions.
10628
10629 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
10630
10631 Warn about dubious constructions like "%token T T".
10632 Reported by twlevo.
10633 * src/symtab.h (struct symbol.declared): New member.
10634 * src/symtab.c (symbol_new): Initialize it to false.
10635 (symbol_class_set): New arg DECLARING, specifying whether
10636 this is a declaration that we want to warn about, if there
10637 is more than one of them. All uses changed.
10638
10639 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
10640 Allow multiple %union directives, whose contents concatenate.
10641 * src/parse-gram.y (grammar_declaration): Likewise.
10642 Use muscle_code_grow, so that we don't need stype_line any more.
10643 All uses changed.
10644
10645 * src/muscle_tab.c (muscle_grow): Fix comment.

10655 (b4_parse_param): Improve its definition, and bound it more
10656 clearly in the skeleton.
10657 (b4_epilogue): Append, instead of prepending, in order to keep
10658 #line consistency.
10659 Simplify the generation of auxiliary functions: locations and
10660 purity are mandated.
10661 (b4_global_tokens_and_yystype): Honor it.
10662 * data/location.cc (c++.m4): Don't include it.

10664 and AT_SKEL_CC_IF.
10665 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
10666 AT_LALR1_CC_IF.
10667 Be sure to initialize the first position's filename.
10668 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
10669 mandated anyway.

10700 (rule_length_overflow, increment_rule_length, add_column_width):
10701 New functions.
10702 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
10703 (<SC_BRACED_CODE>"}"):

10723
10724 * src/reader.c (grammar_current_rule_check): Also check that $$
10725 is used.
10726 Take the rule to check as argument, hence rename as...
10727 (grammar_rule_check): this.
10728 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
10729 Rename as...
10730 (grammar_rule_begin, grammar_rule_end): these, for consistency.
10731 (grammar_midrule_action, grammar_symbol_append): Now static.
10732 * tests/torture.at (input): Don't rely on the default action
10733 being always performed.
10734 * tests/calc.at: "Set" $$ even when the action is "cut" with
10735 YYERROR or other.
10736 * tests/actions.at (Exotic Dollars): Instead of using unused
10737 values, check that the warning is issued.
10738
10739 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
10740
10741 * NEWS: Improve wording for unused-value warnings.

10772 rule_useful_p.
10773
10774 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
10775
10776 Undo 2005-12-01 tentative license wording change. The wording is
10777 still being reviewed by the lawyers, and we don't want to wait for
10778 them before publishing a test release. For now, revert to the
10779 previous wording.
10780 * NEWS: Undo 2005-12-01 change.
10781 * data/glr.c: Revert to previous license wording.
10782 * data/glr.cc: Likewise.
10783 * data/lalr1.cc: Likewise.
10784 * data/location.cc: Likewise.
10785 * data/yacc.c: Likewise.
10786
10787 * NEWS: Reword %destructor vs YYABORT etc.
10788 * data/glr.c: Use American spacing, for consistency.
10789 * data/glr.cc: Likewise.
10790 * data/lalr1.cc: Likewise.
10791 * data/yacc.c: Likewise.
10792 * data/yacc.c: Reformat comments slightly.
10793 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
10794 for consistency. Fix some spelling errors and reword recently-included
10795 text slightly.
10796 * tests/cxx-type.at: Cast results of malloc, for C++.
10797
10798 2005-12-21 Joel E. Denny <address@hidden>
10799
10800 * tests/cxx-type.at: Construct a tree, count the parents of shared
10801 nodes, and free each node once and only once. Previously, the memory
10802 for semantic values was leaked instead.
10803
10804 2005-12-21 Joel E. Denny <address@hidden>
10805
10806 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
10807 (yylval, yylloc): If pure, #define to yystackp->yyval and
10808 yystackp->yyloc similar to yychar and yynerrs.
10809 (yyparse): If pure, remove local yylval and yylloc. Add local
10810 yystackp to accommodate pure definitions of yylval and yylloc.
10811 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
10812 yylvalp and yyllocp to &yylval and &yylloc.
10813 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
10814 namespace. Previously, nerrs and char were missing, but lval and lloc
10815 weren't necessary.
10816 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
10817 yylvalp and yyllocp parameters since, if pure, these are now always
10818 accessible through yystackp. If not pure, they are still accessible
10819 globally.
10820 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
10821 `if (YYID (N))' to pacify lint.
10822
10823 2005-12-21 Akim Demaille <akim@epita.fr>
10824
10825 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
10826 destroy the RHS symbols of a rule.
10827 * data/yacc.c (yylen): Initialize to 0.
10828 Keep its value to the number of items to possibly shift.
10829 In particular, a regular successful parse that ends on YYFINAL by
10830 a (internal) YYACCEPT must not have yylen != 0.
10831 (yyerrorlab, yyreturn): Pop the RHS.
10832 Reorder a bit to emphasize the `shifting' bits of code.
10833 (YYPOPSTACK): Now accept a number of items to pop.
10834 * data/lalr1.cc: Likewise.
10835 * data/glr.c: Formatting changes.
10836 Use goto instead of fall through.
10837 * doc/bison.texinfo (Destructor Decl): Complete.
10838

10843 * djgpp/config.bat: Replace every occurence of the file name
10844 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
10845 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
10846 * djgpp/config.sed: Replace every occurence of the file name
10847 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
10848 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
10849 * djgpp/djunpack.bat: DJGPP specific file.
10850 * djgpp/fnchange.lst: DJGPP specific file.
10851 * djgpp/README.in: Add new information about how to unpack the bison
10852 source on MSDOS and other systems which have 8.3 file name restrictions
10853 using djunpack.bat and fnchange.lst.

10856
10857 * bootstrap (build_cvs_prefix): Remove; unused.

10859 when getting gnulib.
10860
10861 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
10862
10863 * data/glr.c: Reorder typedef declarations for structs to match order
10864 of struct declarations.
10865 Rename yystack everywhere to yystackp except in yyparse where it's not
10866 a pointer.
10867 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
10868 consistency.
10869 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
10870 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
10871 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
10872 lint.
10873
10874 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
10875
10876 * tests/sets.at (Accept): Fix typos in regular expression used to
10877 sed out the final state number.
10878
10879 Work around portability problem on Solaris 10: flex-generated
10880 files include <stdio.h> before <config.h>, which messes up
10881 because the latter defines __EXTENSIONS__. Address the problem
10882 by creating two new little files that include <config.h> first,
10883 then include the flex-generated files. Rewrite everyone else
10884 to include <config.h> first, as well.
10885 * lib/timevar.c: Always include "config.h".
10886 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

10919 * src/parse-gram.y: Fix minor problems uncovered by lint.
10920 (current_lhs, current_lhs_location): Now static.
10921 (current_assoc): Remove unused variable.
10922
10923 Cleanups so that Bison-generated parsers have less lint.
10924 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
10925 Prepend /*ARGSUSED*/, for lint's sake.
10926 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
10927 definition if 'lint' is defined.
10928 (YYID): New macro (or function, if lint).
10929 All uses of /*CONSTCOND*/0 replaced by YYID(0).
10930 * data/yacc.c: Likewise.
10931 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
10932 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
10933 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
10934 is C++ only.
10935 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
10936 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
10937 Use YYID(0) rather than 0, for lint.
10938 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
10939 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

10948
10949 * data/glr.c (yyprocessOneStack, yyparse): Synchronize the shift for
10950 all stacks.
10951 (yyparse): Iterate another stack in order to call user destructors.
10952 * tests/glr-regression.at (No users destructors if stack 0 deleted):
10953 New test case.
10954 (Duplicated user destructor for lookahead): This test now is expected
10955 to succeed.
10956
10957 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
10958
10959 * NEWS: Document the following change.
10960 * data/yacc.c: Say "parser skeleton" rather than "file", since
10961 it's no longer just a file.
10962 * data/glr.c: Grant a special exception for C GLR parsers, that
10963 reads like the already-existing exception for C LALR(1) parsers.
10964 * data/glr.cc: Likewise.
10965 * data/lalr1.cc: Likewise.
10966 * data/location.cc: Likewise.
10967 * data/yacc.c: Reword the "written by" statement to clarify that
10968 it was the parser skeleton, not the entire output file.
10969 * data/glr.c: Written by Paul Hilfinger.
10970 * data/glr.cc: Written by Akim Demaille.
10971 * data/lalr1.cc: Likewise.
10972
10973 2005-11-18 Paul Eggert <eggert@cs.ucla.edu>
10974
10975 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
10976 Fix typos in previous change that broke 'make check'.
10977 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
10978 supported in C.
10979 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
10980 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
10981 We can revert this once things settle down.
10982
10983 * src/conflicts.c (conflicts_print): Don't print file name twice
10984 when %expect fails because there were no conflicts.
10985 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
10986 change.
10987 * tests/conflicts.at (%expect not enough, %expect too much):

11007 (YY_REDUCE_PRINT): Adjust to pass the required arguments.
11008 (yysymprint): Move higher to be visible from yy_reduce_print).
11009 (yyparse): Adjust.
11010 * tests/calc.at: Adjust the expected length of the traces.
11011
11012 2005-11-14 Akim Demaille <akim@epita.fr>
11013
11014 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
11015 from 1 to N, while values and location start at 0.
11016 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
11017
11018 2005-11-14 Akim Demaille <akim@epita.fr>
11019

11023
11024 "Use" parse parameters.
11025 * data/c.m4 (b4_parse_param_for, b4_parse_param_use): New.
11026 * data/glr.c, data/glr.cc: Use them.
11027 * data/glr.c (YYUSE): Have a C++ definition that supports
11028 non-pointer types.
11029

11119 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
11120
11121 * bootstrap (cleanup_gnulib): New function. Use it to clean up
11122 gnulib when interrupted. This fixes some race conditions and
11123 works around some portability problems (one noted by Paul
11124 Hilfinger).
11125
11126 2005-10-22 Akim <akim@epita.fr>
11127
11128 * Makefile.cfg: Adjust to config -> build-aux.

11153
11154 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
11155
11156 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
11157 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.

11164 additional checks.
11165 Use this to exercise C++ outputs in subdirs.
11166 Reported by Oleg Smolsky.
11167
11168 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
11169
11170 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
11171 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
11172 Problem reported by John P. Hartmann.
11173 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
11174 already defined it.
11175

11209 (YYCHK1):
11210 Use /*CONSTCOND*/ to suppress lint warnings.

11224 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
11225
11226 Undo the parts of the unlocked-I/O change that substituted
11227 putc or puts for printf. This might hurt performance a bit,
11228 but some people prefer the printf style.
11229 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
11230 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

11251 unused-variable warnings.
11252
11253 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

11256
11257 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
11258
11259 Use unlocked I/O for a minor performance improvement on hosts like
11260 GNU/Linux and Solaris that support unlocked I/O. The basic idea
11261 is to use the gnlib unlocked-io module, and to prefer putc and
11262 puts to printf when either will work (since the latter doesn't
11263 come in an unlocked flavor).
11264 * bootstrap (gnulib_modules): Add unlocked-io.
11265 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
11266 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

11268 and similarly for puts and putc and printf.
11269 * data/yacc.c: Likewise.
11270 * lib/bitset.c (bitset_print): Likewise.
11271 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

11284
11285 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
11286 this confuses xgettext.

11332 for posix systems.
11333
11334 * lib/subpipe.h: New function end_of_output_subpipe() added
11335 to allow support for non-posix systems. This is a no-op function

11361 (location.hh): Include it after the user prologue, in case the
11362 filename type is defined by the user.
11363 Forward declation location and position before the pre-prologue.

11456 2005-09-20 Akim Demaille <akim@epita.fr>
11457
11458 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
11459
11460 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
11461
11462 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
11463 (YYSTACK_ALLOC_MAXIMUM): Use it.
11464 (yysyntax_error): New function.
11465 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
11466 multiple syntax errors are reported, and alloca is being used.
11467 Instead, reallocate buffers twice as big each time, so that
11468 we waste at most half the allocated memory. Start with a small
11469 (128-byte) buffer that will suffice in most cases anyway.
11470 Use yysyntax_error to do most of the work.
11471
11472 * doc/bison.texinfo (Error Reporting, Table of Symbols):
11473 yynerrs is the number of errors reported, not the number of
11474 errors encountered.
11475
11476 * tests/glr-regression.at (Duplicated user destructor for lookahead):
11477 Mark it as expected to fail.
11478 Cast result of malloc; problem reported by twlevo@xs4all.nl.
11479 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
11480 Don't start user-code symbols with "yy", to avoid name space problems.
11481
11482 2005-09-19 Akim Demaille <akim@epita.fr>
11483
11484 Remove the traits, failed experiment.
11485 It never proved useful, and anyway because of the current
11486 definition, it was not possible to have several specialization of
11487 this traits, making it useless.
11488 * data/lalr1.cc (yy:traits): Remove.
11489 Inline its definitions in the parser class.
11490
11491 2005-09-19 Akim Demaille <akim@epita.fr>
11492
11493 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
11494 least Mac OSX with a /usr/local install of gettext.
11495
11496 2005-09-19 Akim Demaille <akim@epita.fr>
11497
11498 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
11499 and yytoken for similarity with the other skeletons.
11500
11501 2005-09-19 Akim Demaille <akim@epita.fr>
11502
11503 * NEWS, configure.ac: update version number to 2.1a.
11504
11505 2005-09-16 Paul Eggert <eggert@cs.ucla.edu>
11506
11507 * NEWS: Version 2.1.
11508
11509 * NEWS: Remove notice of yytname change, since it was never in an
11510 official release.
11511 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
11512 diagnostic.
11513 * src/output.c (prepare): Likewise.
11514 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
11515 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
11516 is not defined. This is an awful hack, but it's enough for now.
11517 All callers changed.
11518 * tests/glr-regression-at (make_value): Args are const pointers now,
11519 to avoid GCC warning.
11520 (Duplicated user destructor for lookahead): New test. Currently
11521 skipped. It fails on my host but I'm not sure it'll always fail.
11522
11523 2005-09-16 Akim Demaille <akim@epita.fr>
11524
11525 * src/symtab.h (struct symbol): Declare the printer and destructor
11526 as const, to avoid accidental calls to free.
11527 (symbol_destructor_set, symbol_printer_set): Adjust.
11528 * src/symtab.c: Adjust.
11529
11530 2005-09-16 Akim Demaille <akim@epita.fr>
11531
11532 * data/c.m4 (b4_token_enums): New.
11533 (b4_token_defines): Rename as...
11534 (b4_token_enums_defines): this.
11535 (b4_token_defines): New, output only the #defines.
11536 * data/yacc.c, data/glr.c: Adjust.
11537 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
11538 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
11539 as default values.
11540
11541 2005-09-16 Akim Demaille <akim@epita.fr>
11542
11543 * data/lalr1.cc (yylex_): Remove, inline its code.
11544 (yyreport_syntax_error_): Remove, replaced by...
11545 (yysyntax_error_): this which returns a string and leaves to the
11546 caller the call to the users' error function.
11547 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
11548 Move from members of the parser object...
11549 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
11550 to local variables of the parse function.
11551
11552 2005-09-16 Akim Demaille <akim@epita.fr>
11553
11554 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
11555 since it's in Bison's name space.
11556
11557 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
11558
11559 * data/glr.c (yyresolveValue): Add default case to pacify
11560 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
11561
11562 * NEWS: Document when yyparse started to return 2.
11563 * doc/bison.texinfo (Parser Function): Document when yyparse
11564 returns 2.
11565
11566 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
11567 (b4_filename_type): Renamed back from b4_file_name_type. All uses
11568 changed.
11569 (class position): file_name -> filename (reverting). All uses changed.
11570
11571 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
11572
11573 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
11574 do anything if $@ exists. This reverts part of the 2005-07-07
11575 patch.
11576
11577 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
11578
11579 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
11580 contains obsolete information and isn't worth distributing as a
11581 separate file anyway.
11582 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
11583 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
11584 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
11585 (yyparse): Abort if user code uses longjmp to throw an unexpected
11586 value.
11587
11588 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
11589
11590 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
11591 Suggested by twlevo@xs4all.nl.
11592
11593 * data/glr.c (YYCHK1): Do not assume YYE is in range.
11594 This avoids a diagnostic from gcc -Wswitch-enum.
11595 Problem reported by twlevo@xs4all.nl.
11596
11597 * doc/bison.texinfo: Don't use "filename", as per GNU coding
11598 standards. Use "file name" or "file" or "name", depending on
11599 the context.
11600 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
11601 not to hack/foo.tab.c.
11602 (Calc++ Top Level): 2nd arg of main is not const.
11603 * data/glr.c: b4_filename -> b4_file_name.
11604 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
11605 All uses changed.
11606 (class position): filename -> file_name. All uses changed.
11607 * data/yacc.c: b4_filename -> b4_file_name.
11608 * lib/bitset.h: filename -> file_name in local vars.
11609 * lib/bitset_stats.c: Likewise.
11610 * src/files.c: Likewise.
11611 * src/scan-skel.l ("@output ".*\n): Likewise.
11612 * src/files.c (file_name_split): Renamed from filename_split.
11613 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
11614
11615 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
11616
11617 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
11618 to accommodate latest gnulib.
11619
11620 * tests/glr-regression.at (Duplicate representation of merged trees):
11621 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
11622
11623 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
11624 needed.
11625
11626 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11627
11628 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
11629 All uses changed. Invoke user destructor after an error during a
11630 split parse (trivial change from Joel E. Denny).
11631
11632 * tests/glr-regression.at
11633 (User destructor after an error during a split parse): New test case.
11634 Problem reported by Joel E. Denny in:
11635 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
11636
11637 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11638
11639 * README-cvs: Give URLs for recommended tools.
11640 Mention Gzip version problem, and bootstrapping issues.
11641 Remove troubleshooting section, as it's somewhat obsolete.
11642
11643 * bootstrap (no_cache): New var, to accommodate different wget
11644 variants. Use it instead of '-C off'. Problem reported by
11645 twlevo@xs4all.nl.
11646
11647 * data/glr.c (yydestroyStackItem): New function.
11648 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
11649 debugging information. Problem reported by Joel E. Denny.
11650
11651 2005-08-25 Akim Demaille <akim@epita.fr>
11652
11653 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
11654
11655 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
11656
11657 * data/glr.c (yyrecoverSyntaxError, yyreturn):
11658 Don't invoke destructor on unresolved entries.
11659 * tests/glr-regression.at
11660 (User destructor for unresolved GLR semantic value): New test case.
11661 Problem reported by Joel E. Denny in:
11662 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
11663
11664 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
11665
11666 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
11667 Add strnlen.c.
11668 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
11669 lib-prefix.m4, po.m4.
11670
11671 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
11672 in yydestruct diagnostic, since it might not be an error.
11673 Problem reported by Joel Denny near end of
11674 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
11675 * data/lalr1.cc (yyerturn): Likewise.
11676 * data/yacc.c (yyreturn): Likewise.
11677 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
11678
11679 * src/files.c: Remove obsolete FIXME comment.
11680
11681 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
11682 with the other templates, and to fix bogus run-on messages such
11683 as the one reported at the end of
11684 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
11685 All callers changed to avoid the newline.
11686 (yyprocessOneStack): Output two lines rather than one, to accommodate
11687 the above change. This changes the debug output format slightly.
11688
11689 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
11690 reported by Joel E. Denny in
11691 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
11692 (trivial change).
11693 * tests/glr-regression.at (Duplicate representation of merged trees):
11694 New test, from Joel E. Denny in:
11695 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
11696 * THANKS: Add Joel E. Denny.
11697
11698 * configure.ac (AC_INIT): Bump to 2.0c.
11699
11700 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
11701
11702 * NEWS: Version 2.0b.
11703
11704 * Makefile.am (SUBDIRS): Put examples before tests, so that
11705 "make check" doesn't finish with "All 1 tests passed".
11706
11707 * tests/regression.at (Token definitions): Don't rely on
11708 AT_PARSER_CHECK for data that contains backslashes. It currently
11709 uses 'echo', and 'echo' isn't portable if its argument contains
11710 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
11711 that the byte '\0xff' is not printable in the C locale; it is,
11712 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
11713 not printable, so use '\0x81' to test.
11714
11715 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
11716 version of GCC, since the macro is used with non-GCC compilers.
11717
11718 Fix core dump reported by Pablo De Napoli in
11719 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
11720 * tests/regression.at (Invalid inputs with {}): New test.
11721 * src/parse-gram.y (token_name): Translate type before using
11722 it as an index.
11723
11724 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
11725 the user's name space. All uses changed to __attribute__
11726 ((__unused__)).
11727 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
11728 Add __attribute__ ((__noreturn__)).
11729
11730 * etc/clcommit: Remove. We weren't using it, and it failed
11731 "make maintainer-distcheck".
11732 * Makefile.maint: Merge from coreutils.
11733 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
11734 (syntax-check-rules): Change list of rules as described below.
11735 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
11736 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
11737 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
11738 (sc_trailing_space): New rules.
11739 (sc_xalloc_h_in_src): Remove.
11740 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
11741 (sc_space_tab, sc_error_exit_success, sc_changelog):
11742 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
11743 (makefile-check, po-check, author_mark_check):
11744 (makefile_path_separator_check, copyright-check):
11745 Use grep -n, to make it easier to find violations.
11746 Use CVS_LIST and CVS_LIST_EXCEPT.
11747 (header_regexp, h_re): Remove.
11748 (dd_c): New macro.
11749 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
11750 (my-distcheck): Use more-modern GCC flags.
11751 (signatures, %.asc): Remove.
11752 (rel-files, announcement): Remove signatures.
11753 Restore old updating code, even though we don't use it, so
11754 that we're the same as coreutils.
11755 (alpha, beta, major): Depend on news-date-check.
11756 Make the upload commands.
11757
11758 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
11759 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
11760 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
11761 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
11762 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
11763 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
11764 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
11765 * tests/sets.at: Likewise.
11766
11767 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
11768 we comment out the Autoconf version number.
11769 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
11770 it's error-prone and "make maintainer-distcheck" rejects it.
11771
11772 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
11773 Indent calls to "error" to pacify "make maintainer-distcheck",
11774 when the calls are not intended to be translated.
11775 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
11776
11777 * src/Makefile.am (DEFS): Use +=, to pacify
11778 "make maintainer-distcheck".
11779 (bison_SOURCES): Add scan-skel.h.
11780 (sc_tight_scope): New rule, from coreutils.
11781
11782 * src/files.c (src_extension, header_extension):
11783 Now static, not extern.
11784 * src/getargs.c (short_options): Likewise.
11785 * src/muscle_tab.c (muscle_table): Likewise.
11786 * src/parse-gram.y (current_class, current_type, current_prec):
11787 Likewise.
11788 * src/reader.c (grammar_end, previous_rule_end): Likewise.
11789 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
11790 * src/main.c (main): Cast bindtextdomain and textdomain calls to
11791 void, to avoid warning when NLS is disabled.
11792 * src/output.c: Include scan-skel.h.
11793 (scan_skel): Remove decl, since scan-skel.h does this.
11794 (output_skeleton):
11795 Indent calls to "error" to pacify "make maintainer-distcheck".
11796 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
11797 * src/reader.h (gram_end, gram_lineno): New decls to pacify
11798 "make maintainer-distcheck".
11799 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
11800 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
11801 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
11802 (skel_lex_destroy, scan_skel): Move these decls to...
11803 * src/scan-skel.h: New file.
11804 * src/uniqstr.c (uniqstr_assert):
11805 Indent calls to "error" to pacify "make maintainer-distcheck".
11806
11807 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
11808 not @VAR@.
11809
11810 * tests/torture.at: Revamp to avoid misuse of atoi that
11811 "make maintainer-distcheck" complained about.
11812
11813 * examples/extexi (message): Don't print a message more than once,
11814 and omit line-number decoration that makes Emacs compile think
11815 that informative messages are worth worrying about.
11816
11817 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
11818
11819 * configure.ac: Update version number.
11820
11821 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
11822 accidentally.
11823 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
11824 autogenerated by the maintainer.
11825 * examples/calc++/.cvsignore: Add *.yy.
11826
11827 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
11828 * lib/bitset_stats.c (bitset_stats_init): Likewise.
11829 * lib/bitsetv.c (bitsetv_alloc): Likewise.
11830
11831 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
11832
11833 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
11834 from maintainer-distcheck about casting the argument of 'free'.
11835
11836 * NEWS: Mention recent yytname changes.
11837 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
11838
11839 * bootstrap: For translations that have not yet been upgraded to
11840 the new runtime-po domain, prime the pump by extracting the
11841 relevant strings from the obsolete translations. This code can be
11842 removed once the bison-runtime domain has been translated by each
11843 team.
11844
11845 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
11846 now that token names are already quoted.
11847
11848 Fix problem reported by Anthony Heading.
11849 * data/glr.c (YYTOKEN_TABLE): New macro.
11850 (yytname): Define if YYTOKEN_TABLE.
11851 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
11852 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
11853 (YYERROR_VERBOSE): Define the same way the other skeletons do.
11854 * src/output.c (prepare_symbols): Output token_table_flag.
11855
11856 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
11857
11858 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
11859 again if the first call fails.
11860
11861 * data/glr.c (yytnamerr): New function.
11862 (yyreportSyntaxError): Use it to dequote most string literals.
11863 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
11864 with other skeletons. All uses changed.
11865 (yytnameerr_): New function.
11866 (yyreport_syntax_error): Use it to dequote most string literals.
11867 * data/yacc.c (yytnamerr): New function.
11868 (yyerrlab): Use it to decode most string literals.
11869 * doc/bison.texinfo (Decl Summary, Calling Convention):
11870 Clarify quoting convention of yytname.
11871 * src/output.c (prepare_symbols): Quote all names. This undoes
11872 the 2005-04-17 change, which is now accomplished (mostly) via
11873 changes in the parsers as described above.
11874 * tests/regression.at (Token definitions, Web2c Actions):
11875 Undo most 2005-04-17 change here, too.
11876
11877 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
11878
11879 Fix more problems reported by twlevo@xs4all.nl.
11880 * tests/cxx-type.at: Don't pipe output of ./types through sed to
11881 remove trailing spaces. This loses the exit status of ./types,
11882 and isn't needed since ./types shouldn't be emitting trailing
11883 spaces.
11884 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
11885 as the stack isn't valid in that case.
11886
11887 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
11888 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
11889 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
11890 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
11891 is used.
11892 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
11893 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
11894 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
11895 Likewise.
11896
11897 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
11898 overly-picky compilers that reject 'char *foo = "bar";'.
11899
11900 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
11901 to FILE * parameter, not to stderr. This fixes a typo introduced
11902 in the 2005-07-12 change.
11903
11904 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
11905 warnings from GCC 4.
11906
11907 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
11908 (yyglrShiftDefer, yysplitStack):
11909 Remove unused parameters b4_pure_formals. All uses changed.
11910 (yyglrShift): Remove unused parameters b4_user_formals.
11911 All uses changed.
11912 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
11913
11914 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
11915
11916 Destructor cleanups and regularization among the three skeletons.
11917 * NEWS: Document the behavior changes.
11918 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
11919 stack before failing, as the cleanup code will do it for us now.
11920 * data/lalr1.cc (yyerrlab): Likewise.
11921 * data/glr.c (yyparse): Pop everything off the stack before
11922 freeing it, so that destructors get called properly.
11923 * data/lalr1.cc (yyreturn): Likewise.
11924 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
11925 This is more consistent.
11926 * doc/bison.texinfo (Destructor Decl): Mention more reasons
11927 why destructors might be called. 1.875 -> 2.1.
11928 (Destructor Decl, Decl Summary, Table of Symbols):
11929 Some English-language cleanups for %destructor.
11930 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11931 Add output line for destructor of start symbol.
11932 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
11933 because of that same extra output line.
11934
11935 * NEWS: Document minor wording changes in diagnostics of
11936 Bison-generated parsers.
11937 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
11938 Remove unused formals. All uses changed.
11939 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
11940 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
11941 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
11942 Rename yyoverflowab to yyexhaustedlab.
11943 When memory exhaustion occurs during syntax-error reporting,
11944 report it separately rather than in a single diagnostic; this
11945 eases translation.
11946 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
11947 (Memory Exhausted): Renamed from Parser Stack Overflow.
11948 Revamp wording slightly to prefer "memory exhaustion".
11949 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
11950
11951 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
11952
11953 Add i18n support to the GLR skeleton. Partially fix the C++
11954 skeleton; a C++ expert needs to finish this. Remove debugging
11955 msgids; there's little point to having them translated, since they
11956 can be understood only by someone who can read the
11957 (English-language) source code.
11958
11959 Generate runtime-po/bison-runtime.pot automatically, so that we
11960 don't have to worry about garbage getting in that file. We'll
11961 make sure after the next official release that old msgids don't
11962 get lost. See
11963 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
11964
11965 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
11966 Now auto-generated.
11967 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
11968 Fix typos in explanations of the runtime file.
11969 * bootstrap: Change gettext keyword from YYI18N to YY_.
11970 Use standard Makefile.in.in in runtime-po, since we'll arrange
11971 for backward-compatible bison-runtime.po files in a different way.
11972 * data/glr.c (YY_): New macro, from yacc.c.
11973 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
11974 Translate messages intended for users.
11975 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
11976 the wording in the other skeletons. We don't know that the memory
11977 is virtual.
11978 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
11979 Use same method that yacc.c uses.
11980 Don't translate debugging messages.
11981 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
11982 it doesn't work (yet), and requires C++ expertise to fix.
11983 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
11984 Move defn to a more logical place, to be consistent with other
11985 skeletons.
11986 Don't translate debugging messages.
11987 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
11988 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
11989 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
11990 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
11991
11992 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
11993 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
11994 void, not int.
11995 * tests/glr-regression.at (Badly Collapsed GLR States):
11996 Likewise.
11997 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11998 yylex should return 0 at EOF rather than aborting.
11999
12000 Improve tests for stack overflow in GLR parser.
12001 Problem reported by twlevo@xs4all.nl.
12002 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
12003 All uses removed.
12004 (yyStackOverflow): Just longjmp, but with value 2 so that caller
12005 can handle the problem.
12006 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
12007 (yyparse): New local variable yyresult to record the result.
12008 Use result of setjmp to set it, rather than storing itinto
12009 struct.
12010 (yyDone): Remove label.
12011 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
12012 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
12013 if YYABORT is used).
12014 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
12015 yyparse status; put status > 1 into diagnostic.
12016 Check that status==2 works.
12017 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
12018 Use exit status 3 for failure to open (which shouldn't happen).
12019
12020 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
12021
12022 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
12023 1 on syntax error; just let yyparse do its thing.
12024 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
12025 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
12026 (Exploding the Stack Size with Alloca):
12027 (Exploding the Stack Size with Malloc):
12028 Expect exit status 2, not 1, since the parser is supposed to blow
12029 its stack. Problem reported by twlevo@xs4all.nl.
12030
12031 * data/glr.c (yyparse): Don't assume that the initial calls
12032 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
12033 Print a stack-overflow message and fail instead.
12034 Initialize the line-number information before creating the stack,
12035 so that the stack-overflow message can report line zero safely.
12036
12037 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
12038
12039 Fix problems reported by twlevo@xs4all.nl.
12040 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
12041 (yyuserMerge): Provide a default case if b4_mergers is empty.
12042 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
12043 * tests/glr-regression.at
12044 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
12045 Add casts to pacify C++ compilers.
12046 * tests/glr-regression.at (Improper merging of GLR delayed action
12047 sets): Declare yylex before using it.
12048 * tests/Makefile.am (maintainer-check-g++): Fix a stray
12049 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
12050 test for valgrind; valgrind is independent of g++.
12051 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
12052 for compatibility with POSIX 1003.1-2001 (if running coreutils).
12053 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
12054 Use a destructor, so that we can expand the stack. Change
12055 YYSTYPE to char * so that we can free it. Cast result of malloc.
12056
12057 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12058
12059 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
12060 a valgrind failure. Problem reported by twlevo@xs4all.nl.
12061
12062 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
12063
12064 * PACKAGING: New file, suggested by Bruno Haible and taken from
12065 similar wording in gettext's PACKAGING file.
12066 * NEWS: Mention PACKAGING.
12067 * Makefile.am (EXTRA_DIST): Add PACKAGING.
12068
12069 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
12070
12071 * NEWS: Document recent i18n improvements.
12072 * bootstrap: Get runtime translations into runtime-po.
12073 Create runtime-po files automatically, if possible.
12074 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
12075 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
12076 does not infringe on the user's name space.
12077 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
12078 * doc/bison.texinfo (Internationalization): Revamp the English
12079 and Texinfo syntax a bit, to try to make it clearer.
12080 (Bison Options, Option Cross Key): Mention --print-localedir.
12081 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
12082 YYENABLE_NLS. Quote a bit more.
12083 * runtime-po/.cvsignore: New file.
12084 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
12085 * runtime-po/Rules-quot: Remove; now created by bootstrap.
12086 * runtime-po/quot.sed: Likewise.
12087 * runtime-po/boldquot.sed: Likewise.
12088 * runtime-po/en@quot.header: Likewise.
12089 * runtime-po/en@boldquot.header: Likewise.
12090 * runtime-po/insert-header.sin: Likewise.
12091 * runtime-po/remove-potcdate.sin: Likewise.
12092 * runtime-po/Makevars: Likewise.
12093 * runtime-po/LINGUAS: Likewise.
12094 * runtime-po/de.po: Likewise; we will rely on the translation project
12095 to maintain this, so "bootstrap" should get it.
12096 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
12097 its value.
12098 * src/main.c (main): Bind the bison-runtime domain, too.
12099
12100 2005-07-12 Bruno Haible <bruno@clisp.org>
12101
12102 * data/yacc.c: Include <libintl.h> when NLS is enabled.
12103 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
12104 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
12105 * runtime-po: New directory.
12106 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
12107 $(DOMAIN).pot-update rule, so that old messages are never dropped.
12108 * runtime-po/Rules-quot: New file, copied from po/.
12109 * runtime-po/quot.sed: Likewise.
12110 * runtime-po/boldquot.sed: Likewise.
12111 * runtime-po/en@quot.header: Likewise.
12112 * runtime-po/en@boldquot.header: Likewise.
12113 * runtime-po/insert-header.sin: Likewise.
12114 * runtime-po/remove-potcdate.sin: Likewise.
12115 * runtime-po/Makevars: New file.
12116 * runtime-po/POTFILES.in: New file.
12117 * runtime-po/LINGUAS: New file.
12118 * runtime-po/bison-runtime.pot: New file.
12119 * runtime-po/de.po: New file.
12120 * m4/bison.m4: New file.
12121 * Makefile.am (SUBDIRS): Add runtime-po.
12122 (aclocaldir, aclocal_DATA): New variables.
12123 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
12124 Define aclocaldir.
12125 * src/getargs.c (usage): Document --print-localedir option.
12126 (PRINT_LOCALEDIR_OPTION): New enum item.
12127 (long_options): Add --print-localedir option.
12128 (getargs): Handle --print-localedir option.
12129 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
12130 (Internationalization): New section.
12131
12132 2005-07-12 Akim Demaille <akim@epita.fr>
12133
12134 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
12135 for consistency with the rest of the code.
12136 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
12137 Add separators.
12138
12139 2005-07-12 Akim Demaille <akim@epita.fr>
12140
12141 * src/parse-gram.y: Use %printer instead of YYPRINT.
12142
12143 2005-07-12 Akim Demaille <akim@epita.fr>
12144
12145 * src/symtab.h, src/symtab.c (symbol_print): New.
12146 * src/symlist.h, src/symlist.c (symbol_list_print): New.
12147 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
12148
12149 2005-07-12 Akim Demaille <akim@epita.fr>
12150
12151 * data/glr.c (b4_syncline): Fix (swap) the definitions of
12152 b4_at_dollar and b4_dollar_dollar.
12153
12154 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
12155
12156 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
12157 and Pennello's paper.
12158
12159 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
12160
12161 * data/yacc.c (yyparse): Undo previous patch. Instead,
12162 set yylsp[0] and yyvsp[0] only if the initial action
12163 sets yylloc and yylval, respectively.
12164
12165 * data/yacc.c (yyparse): In the initial action, set
12166 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
12167 This avoids the use of undefined variables if the initial
12168 action does not set yylloc and/or yylval.
12169
12170 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12171
12172 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
12173 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
12174 Remove from CVS. These files are automatically generated.
12175 * examples/extexi: Clarify that this file is now part of Bison,
12176 not GNU M4, and that it works with any POSIX-compatible Awk.
12177 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
12178 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
12179 so that we also get calc++-parser.yy. Geneate it.
12180 Use $(AWK), not gawk, since any conforming Awk will do.
12181 Put comment before action, since older 'make' can't handle comment
12182 in action.
12183 $(BUILT_SOURCES): List all built sources, not just some of them.
12184 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
12185 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
12186 $($(calc_sources_generated)): Remove unnecessary test for existence
12187 of target. (This had a shell syntax error anyway; a stray "x".)
12188 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
12189 calc++-parser.yy.
12190 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
12191
12192 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
12193 implied by the other modules.
12194
12195 2005-07-06 Akim Demaille <akim@epita.fr>
12196
12197 Bind examples/calc++ to the package.
12198 * examples/calc++/Makefile: Remove, replaced by...
12199 * examples/calc++/Makefile.am: ... this new file.
12200 * examples/calc++/test: Remove input.
12201 * examples/calc++/compile: Remove.
12202 * examples/Makefile.am: New.
12203 * configure.ac, Makefile.am: Adjust.
12204 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
12205
12206 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
12207
12208 * data/glr.c (yyFail): Drastically simplify; since the format argument
12209 never had any % directives, we can simply pass it to yyerror.
12210 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
12211 be modified later, as that is the usual style in glr.c.
12212 Problems reported by Paul Hilfinger.
12213
12214 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
12215 and size overflow errors.
12216 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
12217 in case the user prolog sets feature-test macros like _GNU_SOURCE.
12218 (YYSIZEMAX): New macro.
12219 (yystpcpy): New function, taken from yacc.c.
12220 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
12221 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
12222 so that we don't have to maintain their signatures.
12223 (yyFail): Check for buffer overflow, by using vsnprintf rather
12224 than vsprintf. Allocate a bigger buffer if possible.
12225 Report an error if buffer allocation fails.
12226 (yyStackOverflow): New function.
12227 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
12228 the initialization was successful. It might fail if storage was
12229 exhausted.
12230 (yyexpandGLRStack): Add more checks for storage allocation failure.
12231 Use yyStackOverflow to report failures.
12232 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
12233 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
12234 Don't assume stack number fits in int.
12235 (yysplitStack): Check for storage allocation failure.
12236 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
12237 can print diagnostics on storage allocation failure. All callers
12238 changed.
12239 (yyresolveValue): Use yybool for boolean.
12240 (yyreportSyntaxError): Check for size-calculation overflow.
12241 This code is taken from yacc.c.
12242 (yyparse): Check for storage allocation errors when allocating
12243 the initial stack.

12246
12247 Extract calc++ from the documentation.
12248 * doc/bison.texinfo (Calc++): Add the extraction marks.
12249 * examples/extexi: New, from the aborted GNU Programming 2E.
12250 Separate the different paragraph of a file with empty lines.
12251 * examples/Makefile: Use it to extract the whole calc++ example.
12252
12253 2005-06-24 Akim Demaille <akim@epita.fr>
12254
12255 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
12256 class typedefs.
12257
12258 2005-06-22 Akim Demaille <akim@epita.fr>
12259
12260 * doc/bison.texinfo (C++ Language Interface): First stab.
12261 (C++ Parsers): Remove.
12262
12263 2005-06-22 Akim Demaille <akim@epita.fr>
12264
12265 * data/lalr1.cc (yylex_): Honor %lex-param.
12266
12267 2005-06-22 Akim Demaille <akim@epita.fr>
12268
12269 Start a set of simple examples.
12270 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,

12275
12276 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
12277
12278 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
12279 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
12280 which stems from the 2005-05-27 patch.
12281
12282 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
12283
12284 * data/glr.c: Modify treatment of unused parameters to permit use
12285 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
12286
12287 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
12288
12289 Fix infringement on user name space reported by Janos Zoltan Szabo.
12290 * data/yacc.c (yyparse): strlen -> yystrlen.
12291
12292 2005-05-30 Akim Demaille <akim@epita.fr>
12293
12294 * data/lalr1.cc (_): New.
12295 Translate the various messages.
12296
12297 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
12298
12299 Fix infringement on user name space reported by Bruno Haible.
12300 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
12301 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
12302 the user's name space.
12303 (alloca): Include <stdlib.h> to get it, if it's not built in.
12304 (YYMALLOC, YYFREE): Define only if needed.
12305 (malloc, free): Declare, but only if needed, as this infringes on
12306 the user name space.
12307
12308 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12309
12310 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
12311 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
12312 with %d format.
12313 * lib/ebitset.c (min, max): Undef before defining.
12314 * lib/vbitset.c (min, max): Likewise.
12315 * lib/subpipe.c (create_subpipe): Save local variables in case
12316 vfork clobbers them.
12317
12318 2005-05-24 Bruno Haible <bruno@clisp.org>
12319
12320 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
12321 error message syntax used by gcc-4.0.
12322
12323 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
12324
12325 * README: Mention m4 1.4.3. Remove obsolete advice about
12326 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
12327
12328 * bootstrap: Remove workaround for problem I encountered with
12329 gettext 0.14.1; it seems to be fixed now.
12330
12331 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
12332
12333 * NEWS: Version 2.0a.
12334
12335 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
12336 the previous change.
12337
12338 Various maintainer cleanups.
12339 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
12340 conftest*, for benefit of CVS commands run at the same time as
12341 "configure". Add build-aux, since "bootstrap" now creates it and
12342 its subfiles.
12343 * Makefile.cfg (move_if_change): Remove.
12344 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
12345 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
12346 (po_repo, do-po-update, po-update, wget_files, get-targets):
12347 (config.guess-url_prefix, config.sub-url_prefix):
12348 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
12349 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
12350 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
12351 Remove.
12352 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
12353 this is now the recommended name.
12354 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
12355 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
12356 ylwrap. These files now go into build-aux.
12357 * config/move-if-change: Remove.
12358 * config/prev-version.txt: Bump from 1.75 to 2.0.
12359
12360 * bootstrap: Add stdio-safer, unistd-safer modules.
12361 Remove m4/glibc2.m4 (introduced by latest gnulib, but
12362 we don't need it).
12363 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
12364 fopen-safer.c, stdio-safer.h, unistd-safer.h.
12365 * lib/subpipe.c: Include "unistd-safer.h".
12366 (create_subpipe): Make sure all the newly-created
12367 file descriptors are > 2, so that diagnostics don't
12368 get sent down them (which might cause Bison to hang, in theory).
12369 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
12370 * src/files.c (xfopen): Use fopen_safer, not fopen.
12371
12372 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
12373 yesterday's yacc.c fix.
12374
12375 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
12376
12377 * data/glr.c, data/lalr1.cc: Update copyright date.
12378
12379 Fix a destructor bug reported by Wolfgang Spraul in
12380 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
12381 * data/yacc.c (yyabortlab): Don't call destructor, and
12382 don't set yychar to EMPTY.
12383 (yyoverflowlab): Don't call destructor.
12384 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
12385 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
12386 since we no longer output the message "discarding lookahead token
12387 end of input ()".
12388
12389 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12390
12391 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
12392 fix a small glitch in debugging output.
12393 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
12394 after YY_SYMBOL_PRINT where needed.
12395
12396 (struct yyGLRState): Add some comments.
12397 (struct yySemanticOption): Add some comments.
12398 (union yyGLRStackItem): Add comment.
12399
12400 (yymergeOptionSets): Correct this to properly perform the union,
12401 avoiding infinite reported by Michael Rosien.
12402 Update comment.
12403
12404 * tests/glr-regression.at: Add test for GLR merging error reported
12405 by M. Rosien.

12444
12445 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
12446
12447 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
12448 Problem reported by Ralf Menzel.
12449
12450 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12451
12452 * tests/actions.at: Test that stack overflow invokes destructors.
12453 From Marcus Holland-Moritz.
12454 * data/yacc.c (yyerrlab): Move the code that destroys the stack
12455 from here....
12456 (yyreturn): to here. That way, destructors are called properly
12457 even if the stack overflows, or the user calls YYACCEPT or
12458 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
12459 (yyoverflowlab): Destroy the lookahead.
12460
12461 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
12462
12463 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
12464
12465 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
12466
12467 * NEWS: Bison-generated C parsers no longer quote literal strings
12468 associated with tokens.
12469 * src/output.c (prepare_symbols): Don't escape strings,
12470 since users don't want to see C escapes.
12471 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
12472 in diagnostics.
12473 * tests/input.at (Torturing the Scanner): Likewise.
12474 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
12475
12476 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
12477
12478 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
12479 the data size is known to be too small and we can't increase it.
12480 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
12481
12482 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
12483
12484 * src/parse-gram.y: Include quotearg.h.
12485 (string_as_id): Quote $1 before using it as a key, since the
12486 lexer no longer quotes it for us.
12487 (string_content): Don't strip quotes, since lexer no longer
12488 quotes it for us.
12489 * src/scan-gram.l: Include quotearg.h.
12490 ("\""): Omit quote.
12491 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
12492 a key, since the rest of the lexer doesn't quote it.
12493 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
12494 * tests/regression.at (Token definitions): Check for backslashes
12495 in token strings.
12496
12497 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
12498 (YYSIZE_T): Define to unsigned long int when using an older compiler.
12499 (yyparse): Revamp code to generate long syntax error message, to
12500 make it easier to translate, and to avoid problems with arithmetic
12501 overflow. Change "virtual memory" to "memory" in diagnostic, since
12502 we don't know whether the memory is virtual.
12503
12504 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12505
12506 * NEWS: Bison-generated C parsers now use the _ macro to
12507 translate strings.
12508 * data/yacc.c (_) [!defined _]: New macro.
12509 All English strings wrapped inside this macro.
12510 * doc/bison.texinfo (Bison Parser): Document _.
12511 * po/POTFILES.in: Include src/parse-gram.c, since it now
12512 includes translateable strings that parse-gram.y doesn't.
12513
12514 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
12515
12516 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
12517 reverting the 2004-10-11 change to this function.
12518 (symbol_check_alias_consistency): Don't call symbol_type_set
12519 if the type name is already correct.
12520 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
12521
12522 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
12523
12524 * tests/regression.at (Token definitions): Don't use a token named
12525 c, as that generates a "#define c ..." that runs afoul of buggy
12526 stdlib.h that uses the identifier c as a member of struct
12527 drand48_data. Problem reported by Horst Wente.
12528
12529 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
12530
12531 * bootstrap: Change translation URL from
12532 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
12533 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
12534 redirection glitches. Problem reported by twlevo@xs4all.nl.
12535
12536 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
12537
12538 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
12539 after operands; POSIX says this isn't portable for the c99 command.
12540
12541 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
12542
12543 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
12544 immediately if a data overrun has occurred; this may help us track
12545 down what may be a spurious failure on MacOS.
12546
12547 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
12548
12549 Respond to problems reported by twlevo@xs4all.nl.
12550
12551 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
12552
12553 * src/vcg.h: Comment fix.
12554 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
12555 (G_CMAX): Change to -1 instead of INT_MAX.
12556
12557 * data/yacc.c (yyparse): Omit spaces before #line.
12558
12559 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
12560
12561 * src/tables.c (state_number_to_vector_number): Put it inside an
12562 "#if 0", since it's not currently used. Problem reported by
12563 Roland McGrath.
12564
12565 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
12566
12567 * src/output.c (escaped_output): Renamed from
12568 escaped_file_name_output, since we now use it for symbol tags as
12569 well. All uses changed.
12570 (symbol_destructors_output, symbol_printers_output):
12571 Escape symbol tags too.
12572 Problem reported by Matyas Forstner in
12573 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
12574
12575 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
12576 not needed.
12577 * src/output.c (user_actions_output, token_definitions_output,
12578 symbol_destructors_output, symbol_printers_output): Likewise.
12579 * src/reader.c (prologue_augment): Likewise.
12580 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
12581
12582 * src/vcg.c (output_edge): Don't quote linestyle arg.
12583 Problem reported by twlevo@xs4all.nl.
12584
12585 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
12586
12587 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
12588 example, reported by Derek M Jones. Also, make the example even
12589 more outrageous, to better illustrate how bad the problem is.
12590
12591 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
12592
12593 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
12594 putsym. Typo reported by Sebastian Piping.
12595
12596 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12597
12598 * doc/bison.texinfo (Language and Grammar): some -> same
12599 (Epilogue): int he -> in the
12600 Typos reported by Sebastian Piping via Justin Pence.
12601
12602 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12603
12604 * tests/glr-regression.at (Improper handling of embedded actions
12605 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
12606 embedded actions and $-N in GLR parsers", work around an Autoconf bug
12607 with dollar signs in test names.
12608 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
12609 for a similar reason.
12610
12611 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12612
12613 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
12614 wants to redefine G_VIEW.
12615
12616 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
12617
12618 * src/vcg.c (get_view_str): Remove case for normal_view.
12619 Problem reported by twlevo@xs4all.nl.
12620
12621 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
12622
12623 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
12624 Problem reported by twlevo@xs4all.nl.
12625
12626 * doc/bison.texinfo: Change @dircategory from "GNU programming
12627 tools" to "Software development". Requested by Richard Stallman
12628 via Karl Berry.
12629
12630 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
12631
12632 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
12633 Problem reported by twlevo@xs4all.nl.
12634
12635 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
12636
12637 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
12638 keyword; it's not needed with modern compilers, and it doesn't
12639 affect correctness with older compilers. Suggested by
12640 twlevo@xs4all.nl.
12641
12642 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
12643
12644 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
12645 gcc -Wswitch-default.
12646 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12647 * data/yacc.c (yyparse): Likewise.
12648
12649 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
12650
12651 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
12652 already. Let config.h define any nonstandard values.
12653
12654 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
12655
12656 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
12657 for the benefit of slower hosts. Problem reported by
12658 Nelson H. F. Beebe.
12659
12660 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
12661
12662 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
12663 being defined and not used.
12664 * data/lalr1.cc (yyparse): Likewise.
12665 Use "if (false)" rather than "if (0)".
12666
12667 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
12668
12669 * TODO: Mention that we should allow NUL bytes in tokens.
12670
12671 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
12672
12673 * src/scan-skel.l (<<EOF>>): Don't close standard output.
12674 Problem reported by Hans Aberg.
12675
12676 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
12677
12678 * src/getargs.c (version): Happy new year; update overall
12679 program copyright date from 2004 to 2005.
12680
12681 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
12682 Problem reported by Hans Aberg.
12683 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
12684 (Output file names.): Add a test for the case when standard output
12685 is closed.
12686
12687 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
12688
12689 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
12690 to fix an oversight in the Bison 2.0 manual.
12691
12692 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
12693
12694 * NEWS: Version 2.0. Reformat the existing news items since
12695 1.875, so that related items are grouped together.
12696 * configure.ac (AC_INIT): Bump version to 2.0.
12697 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
12698
12699 * tests/torture.at (Exploding the Stack Size with Alloca): Set
12700 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
12701 otherwise, we're not testing alloca. Unfortunately there's no
12702 simple way to consult HAVE_ALLOCA here.
12703
12704 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
12705 for yymsg, too.
12706
12707 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
12708 hand. This avoids a warning about comparing int to size_t when
12709 GCC warnings are enabled.
12710
12711 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
12712
12713 * NEWS: Bison-generated parsers no longer default to using the
12714 alloca function (when available) to extend the parser stack, due
12715 to widespread problems in unchecked stack-overflow detection.
12716 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
12717 responsibility to set it to a positive value. This lets the user
12718 specify a value that is not a preprocessor constant.
12719 * data/yacc.c (YYMAXDEPTH): Likewise.
12720 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
12721 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
12722 to be a compile-time constant. However, explain the constraints on it.
12723 Also, explain the constraints on YYINITDEPTH.
12724 (Table of Symbols): Explain that alloca is no longer the default.
12725 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
12726 to 1.
12727
12728 * doc/bison.texinfo (Location Default Action): Mention that n must
12729 be zero when k is zero. Suggested by Frank Heckenbach.
12730
12731 2004-12-22 Akim Demaille <akim@epita.fr>
12732
12733 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
12734 (parser::state_type, parser::semantic_type, parser::location_type):
12735 Private, not public.
12736 (parser::parse): Return ints, not bool.
12737 Returning a bool introduces a problem: 0 corresponds to false, and
12738 it seems weird to return false on success. Returning true changes
12739 the conventions for yyparse.
12740 Alternatively we could return void and send an exception.
12741 There is no clear consensus (yet?).
12742 (state_stack, semantic_stack, location_stack): Rename as...
12743 (state_stack_type, semantic_stack_type, location_stack_type): these.
12744 Private, not public.
12745 * tests/c++.at: New.
12746 * tests/testsuite.at, tests/Makefile.am: Adjust.
12747
12748 2004-12-21 Akim Demaille <akim@epita.fr>
12749
12750 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
12751
12752 2004-12-21 Akim Demaille <akim@epita.fr>
12753
12754 Don't impose std::string for filenames.
12755
12756 * data/lalr1.cc (b4_filename_type): New.
12757 (position::filename): Use it.
12758 (parser.hh): Move the inclusion of stack.hh and location.hh below
12759 the user code, so that needed headers for the filename type can be
12760 included first.
12761 Forward declare them before the user code.
12762 * tests/Makefile.am (check-local, installcheck-local): Pass
12763 TESTSUITEFLAGS to the TESTSUITE.
12764
12765 2004-12-20 Akim Demaille <akim@epita.fr>
12766
12767 Use more STL like names: my_class instead of MyClass.
12768
12769 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
12770 (SemanticStack, SemanticType, StateStack, StateType)
12771 (TokenNumberType, Stack, Slice, Traits, Parser::location)
12772 (Parser::value): Rename as...
12773 (location_stack, location_type, rhs_number_type, semantic_stack)
12774 (semantic_type, state_stack, state_type, token_number_type, stack)
12775 (slice, traits, parser::yylloc, parser::yylval): these.
12776
12777 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
12778
12779 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
12780
12781 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
12782 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12783
12784 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
12785
12786 Remove uses of 'short int' and 'unsigned short int'. This raises
12787 some arbitrary limits. It uses more memory but nowadays that's
12788 not much of an issue.
12789
12790 This change does not affect the generated parsers; that's a different
12791 task, as some users will want to conserve memory there.
12792
12793 Ideally we should use size_t to represent all object counts, and
12794 something like ptrdiff_t to represent signed differences of object
12795 counts; but that will require more code-cleanup than I have the
12796 time to do right now.
12797
12798 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
12799 Use size_t, not int or short int, to count objects.
12800 * src/closure.c (nritemset, closure): Likewise.
12801 * src/closure.h (nritemset, closure): Likewise.
12802 * src/nullable.c (nullable_compute): Likewise.
12803 * src/print.c (print_core): Likewise.
12804 * src/print_graph.c (print_core): Likewise.
12805 * src/state.c (state_compare, state_hash): Likewise.
12806 * src/state.h (struct state): Likewise.
12807 * src/tables.c (default_goto, goto_actions): Likewise.
12808
12809 * src/gram.h (rule_number, rule): Use int, not short int.
12810 * src/output.c (prepare_rules): Likewise.
12811 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
12812 errs, reductions): Likewise.
12813 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
12814 Likewise.
12815 * src/tables.c (vector_number, tally, action_number,
12816 ACTION_NUMBER_MINIMUM): Likewise.
12817 * src/output.c (muscle_insert_short_int_table): Remove.
12818
12819 2004-12-17 Akim Demaille <akim@epita.fr>
12820
12821 * data/lalr1.cc: Extensive Doxygenation.
12822 (error_): Rename as...
12823 (error): this, since it is visible to the user.
12824 Adjust callers.
12825 (Parser::message): Now an automatic variable from...
12826 (Parser::yyreport_syntax_error_): here.
12827 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
12828 Parser::error.
12829 * tests/input.at: Escape $.
12830
12831 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
12832
12833 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
12834 Parenthesize rhs to avoid obscure problems with mistakes like
12835 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
12836 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
12837 b4_rhs_location): Likewise.
12838 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
12839 b4_rhs_location): Likewise.
12840
12841 2004-12-16 Akim Demaille <akim@epita.fr>
12842
12843 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
12844 yacc.c: be sure to stay within yycheck_.
12845 * tests/actions.at: Re-enable C++ tests.
12846
12847 2004-12-16 Akim Demaille <akim@epita.fr>
12848
12849 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
12850 real.
12851
12852 2004-12-16 Akim Demaille <akim@epita.fr>
12853
12854 Use #define to handle the %name-prefix.
12855
12856 * data/glr.c, data/yacc.c: Comment changes.
12857 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
12858 so that one can refer to yylex in the parser file, and have it
12859 renamed, as is the case with other skeletons.
12860
12861 2004-12-16 Akim Demaille <akim@epita.fr>
12862
12863 Move lalr1.cc internals into yy*.
12864
12865 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)
12866 (semantic_stack_, location_stack_, pact_, pact_ninf_, defact_)
12867 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
12868 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)

12870 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
12871 (looka_, ilooka_, error_range_, nerrs_):
12872 Rename as...
12873 (yysemantic_stack_, yylocation_stack_, yystate_stack_)
12874 (yysemantic_stack_, yylocation_stack_, yypact_, yypact_ninf_)
12875 (yydefact_, yypgoto_, yydefgoto_, yytable_, yytable_ninf_)

12879 (yyuser_token_number_max_, yyundef_token_, yyn_, yylen_, yystate_)
12880 (yynerrs_, yylooka_, yyilooka_, yyerror_range_, yynerrs_):
12881 these.
12882
12883 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
12884
12885 Fix some problems reported by twlevo at xs4all.
12886 * src/symtab.c (symbol_new): Report an error if the input grammar
12887 contains too many symbols. This is better than calling abort() later.
12888 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
12889 (struct node, struct graph):
12890 Rename member expand to stretch. All uses changed.
12891 (struct graph): Remove member layoutalgorithm. All uses removed.
12892 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
12893 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
12894 All uses changed.
12895 (N_STRETCH): Rename from N_EXPAND. All uses changed.
12896
12897 2004-12-15 Akim Demaille <akim@epita.fr>
12898
12899 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
12900 Add more Doxygen comments.
12901 (symprint_, stack_print_, reduce_print_, destruct_, pop)
12902 (report_syntax_error_, translate_): Rename as...
12903 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
12904 (yypop_, yyreport_syntax_error_, yytranslate_): this.
12905
12906 2004-12-15 Akim Demaille <akim@epita.fr>
12907
12908 * data/lalr1.cc (lex_): Rename as...
12909 (yylex_): this.
12910 Move the trace here.
12911 Take the %name-prefix into account.
12912 Reported by Alexandre Duret-Lutz.
12913
12914 2004-12-15 Akim Demaille <akim@epita.fr>
12915
12916 Simplify the C++ parser constructor.
12917
12918 * data/lalr1.cc (debug_): Rename as...
12919 (yydebug_): so that the parser's internals are always in the yy*
12920 pseudo namespace.
12921 Adjust uses.
12922 (b4_parse_param_decl): Remove the leading comma as it is now only
12923 called as unique argument list.
12924 (Parser::Parser): Remove the constructor accepting a location and
12925 an initial debugging level.
12926 Remove from the other ctor the argument for the debugging level.
12927 (debug_level_type, debug_level, set_debug_level): New.
12928
12929 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
12930 constructor calls.
12931
12932 2004-12-15 Akim Demaille <akim@epita.fr>
12933
12934 Remove b4_root related material: failure experiment
12935 (which goal was to allow to derive from a class).
12936
12937 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
12938 definitions and uses.
12939
12940 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
12941
12942 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
12943 not 2, since it's not portable to subtract 1 from the start of an
12944 array. The new item 0 is never set or used. All uses changed.
12945
12946 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
12947 the default definition of YYLLOC_DEFAULT. Problem reported
12948 by Frank Heckenbach.
12949
12950 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
12951
12952 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
12953 the normal case and one for the error case. Just use the
12954 first one uniformly. Problem reported by Frank Heckenbach.
12955 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
12956 use exactly the same macro in both places.
12957 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
12958 so that the normal-case YYRHSLOC works for the error case too.
12959 All uses changed.
12960 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
12961 (YYLLOC_DEFAULT): Use the same macro as glr.c.
12962 * doc/bison.texinfo (Location Default Action): Don't claim that
12963 we have an array of locations. Use the same macro for both glr
12964 and lalr parsers. Mention YYRHSLOC. Mention what happens when
12965 the index is 0.
12966
12967 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
12968
12969 * HACKING: Update email addresses to send announcements to.
12970

12972
12973 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
12974
12975 * NEWS: Version 1.875e.
12976 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
12977
12978 * src/scan-skel.l: Include "complain.h", for "fatal".
12979
12980 * src/relation.h (relation_print, relation_digraph):
12981 Relation sizes are of type relation_node, not size_t (this is
12982 merely a doc fix, since the two types are equivalent).
12983 (relation_transpose): Relation sizes are of type relation_node,
12984 not int.
12985 * src/relation.c: Likewise.
12986 (top, infinity): Now of type relation_node, not int.
12987 (traverse, relation_transpose): Use relation_node, not int.
12988
12989 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
12990 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
12991 (yyparse): Remove unused local introduced in 2004-10-25 patch.
12992
12993 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
12994 specifying whether the test should be skipped. Use it tp
12995 specify that the [%defines %skeleton "lalr1.cc"] tests currently
12996 fail on some hosts, and should be skipped.
12997
12998 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
12999
13000 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
13001 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
13002 unless otherwise specified below.
13003
13004 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
13005 to allocate kernel_base, kernel_items, kernel_size, since
13006 they needn't be initialized to 0.
13007 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
13008 * src/closure.c (new_closure): Likewise, for itemset.
13009 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
13010 * src/lalr.c (set_goto_map): Likewise, for temp_map.
13011 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
13012 (build_relations): Likewise for edge, states1, includes.
13013 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
13014 * src/reader.c (packgram): Likewise, for ritem, rules.
13015 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
13016 * src/relation.c (relation_digraph): Likewise for VERTICES.
13017 (relation_transpose): Likewise for new_R, end_R.
13018 * src/symtab.c (symbols_token_translations_init): Likewise for
13019 token_translations.
13020 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
13021 (token_actions): Likewise for yydefact, actrow, conflrow,
13022 conflict_list.
13023 (save_column): Likewise for froms[symno], tos[symno].
13024 (goto_actions): Likewise for state_count.
13025 (pack_table): Likewise for base, pos, check.
13026 (tables_generate): Likewise for width.
13027
13028 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
13029 for initial core. Just have a separate core, so we needn't worry
13030 about whether kernel_size and kernel_base are initialized.
13031
13032 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
13033 kernel_size, kernel_items): Remove unnecessary initialization.
13034 * src/conflicts.c (conflicts): Likewise.
13035 * src/derives.c (derives): Likewise.
13036 * src/muscle_tablc (muscle_insert): Likewise.
13037 * src/relation.c (relation_digraph): Likewise.
13038 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
13039 conflrow, conflict_table, conflict_list, table, check):
13040 Likewise.
13041
13042 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
13043 This is because all callers pass unsigned int.
13044 * src/closure.h (new_closure): Likewise.
13045
13046 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
13047 (build_relations): Initialize includes[i] in all cases.
13048 * src/reader.c (packgram): Always initialize rules[ruleno].prec
13049 and rules[ruleno].precsym. Initialize members in order.
13050 * src/relation.c (relation_transpose): Always initialize new_R[i]
13051 and end_R[i].
13052 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
13053
13054 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
13055 conflict_list[0] was always 0, but now it isn't initialized.
13056
13057 * src/table.c (table_grow): When conflict_table grew, the grown
13058 area wasn't cleared. Fix this.
13059
13060 * lib/.cvsignore: Add strdup.c, strdup.h.
13061 * m4/.cvsignore: Add strdup.m4.
13062
13063 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
13064
13065 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
13066 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
13067 GOTO_NUMBER_MAXIMUM, since we occasionally compute
13068 ngotos + 1 without checking for overflow.
13069 (build_relations): Use END_NODE, not -1, to denote end of edges.
13070 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
13071 build_relations): Use goto_number, not int, for goto numbers.
13072 * src/tables.c (save_column, default_goto): Likewise.
13073
13074 2004-11-23 Akim Demaille <akim@epita.fr>
13075
13076 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
13077 of #defining from yystype.
13078 Don't typedef yystype, C++ does not need it.
13079 This lets it possible to forward declare it as union.
13080
13081 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
13082
13083 * bootstrap (gnulib_modules): Add extensions.

13086 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
13087
13088 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
13089 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
13090 src/system.h, src/tables.c: XFREE -> free, to accommodate
13091 recent change to gnulib xalloc.h.
13092 Problem reported by Jim Meyering.
13093
13094 2004-11-17 Akim Demaille <akim@epita.fr>
13095
13096 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
13097
13098 2004-11-17 Akim Demaille <akim@epita.fr>,
13099 Alexandre Duret-Lutz <adl@gnu.org>
13100
13101 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
13102 changes.
13103 (YYCDEBUG): Adjust.
13104 Use it instead of cdebug_.
13105 (Parser::debug_stream, Parser::set_debug_stream): New.
13106 (Parser::symprint_): Define cdebug_ for temporary backward
13107 compatibility.
13108 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
13109 debug_stream ().
13110
13111 2004-11-17 Akim Demaille <akim@epita.fr>
13112
13113 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
13114 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
13115 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
13116 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

13121 Problem reported by Frank Heckenbach.
13122
13123 2004-10-25 Akim Demaille <akim@epita.fr>
13124
13125 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
13126 Introduce another definition to address simple location arrays.
13127 (yyGLRStack): New member: yyerror_range.
13128 (yyrecoverSyntaxError, yyparse): Update it.
13129 (yyrecoverSyntaxError): Use it when shifting the error token to
13130 have an accurate range, equivalent to the one computed by both
13131 yacc.c and lalr1.cc.
13132 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
13133 that column numbers start at column 0, as per GNU Coding
13134 Standards, the others tests, and the doc.
13135 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
13136 Adjust to the above change (first column is 0).
13137 And adjust the location of the "<error>", now covering the whole
13138 line.
13139
13140 2004-10-22 Akim Demaille <akim@epita.fr>
13141 and Paul Eggert <eggert@cs.ucla.edu>
13142
13143 Remove some arbitrary limits on goto numbers and relations.
13144 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
13145 initial values, since they're never used.
13146 (set_goto_map): ngotos is now unsigned, so test for overflow
13147 by seeing whether it wraps around to zero.
13148 * src/lalr.h (goto_number): Now size_t, not short int.
13149 (GOTO_NUMBER_MAXIMUM): Remove.
13150 * src/relation.c (relation_print, traverse, relation_transpose):
13151 Check for END_NODE rather than looking at sign.
13152 * src/relation.h (END_NODE): New macro.
13153 (relation_node): Now size_t, not short int.
13154
13155 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
13156
13157 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
13158 keyword, not an identifier. Problem reported by Baron Schwartz in
13159 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
13160
13161 2004-10-11 Akim Demaille <akim@epita.fr>
13162
13163 * src/symtab.c (symbol_check_alias_consistency): Also check
13164 type names, destructors, and printers.
13165 Reported by Alexandre Duret-Lutz.
13166 Recode the handling of associativity and precedence in terms
13167 of symbol_precedence_set.
13168 Accept no redeclaration at all, not even equal to the previous
13169 value.
13170 (redeclaration): New.
13171 Use it to factor redeclaration complaints.
13172 (symbol_make_alias): Don't set the type of the alias, let
13173 symbol_check_alias_consistency do it as for other features.
13174 * src/symtab.h (symbol): Add new member prec_location, and
13175 type_location.
13176 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
13177 * tests/input.at (Incompatible Aliases): New.
13178
13179 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
13180
13181 .cvsignore fixes to accommodate gnulib changes,
13182 and the practice of naming build directories "_build".
13183 * .cvsignore: Add "_*". Sort.
13184 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
13185 * m4/.cvsignore: Add "*_gl.m4".
13186
13187 2004-10-06 Akim Demaille <akim@epita.fr>
13188
13189 * src/parse-gram.y (add_param): Fix the truncation of trailing
13190 spaces.
13191
13192 2004-10-05 Akim Demaille <akim@epita.fr>
13193
13194 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
13195 whether the reducion was empty or not. This leaves room to
13196 improve the use of YYLLOC_DEFAULT in such a case.
13197 lalr1.cc is still experimental, so changing this is acceptable.
13198 And finally, there are probably not many users who changed the
13199 handling of locations in GLR, so changing is admissible too.
13200
13201 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
13202 empty reduction, set @$ to an empty location ending the previously
13203 stacked symbol.
13204 Adjust uses to make sure the code is triggered on empty
13205 reductions.
13206 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
13207 expected output: empty reductions have empty locations.
13208
13209 2004-09-29 Akim Demaille <akim@epita.fr>
13210
13211 * data/lalr1.cc: Move towards a more standard C++ coding style
13212 for templates: Class < T > -> Class<T>.
13213
13214 2004-09-29 Akim Demaille <akim@epita.fr>
13215
13216 * data/lalr1.cc: Reinstall the former ctor, for sake of
13217 compatibility, but warn it will be removed.
13218 Move towards a more standard C++ coding style (i.e., type *var ->
13219 type* var).
13220
13221 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
13222
13223 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
13224 since it's less likely to work if NULs are involved in the future.
13225
13226 2004-09-27 Akim Demaille <akim@epita.fr>
13227
13228 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
13229
13230 2004-09-27 Akim Demaille <akim@epita.fr>
13231
13232 * data/lalr1.cc (b4_parse_param_decl_1): New.
13233 (b4_parse_param_decl): Use it to have different names between attribute
13234 and argument names.
13235 (b4_cc_constructor_call): Likewise.
13236
13237 2004-09-24 Akim Demaille <akim@epita.fr>
13238
13239 * src/parse-gram.y (add_param): Strip the leading and trailing
13240 blanks from a formal argument declaration.
13241 (YY_LOCATION_PRINT): New.
13242
13243 2004-09-24 Akim Demaille <akim@epita.fr>
13244
13245 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
13246 after the location.
13247
13248 2004-09-24 Akim Demaille <akim@epita.fr>
13249
13250 * doc/bison.texinfo (Table of Symbols): Sort.
13251
13252 2004-09-21 Akim Demaille <akim@epita.fr>
13253
13254 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
13255 the useless parentheses.
13256 Suggested by Paul Eggert.
13257
13258 2004-09-20 Akim Demaille <akim@epita.fr>
13259
13260 Let the initial-action act on the look-ahead, and use it for the
13261 "initial push" (corresponding to an hypothetical beginning-of-file).
13262 And let lalr1.cc honor %initial-action.
13263
13264 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
13265 example.
13266 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
13267 (Parser::Parser): Remove the ctor that used to initialize it.
13268 (Parser::parse): Like in the other skeletons, issue the "starting
13269 parse" message before any action.
13270 Honor %initial-action.
13271 Initialize the stacks with the lookahead.
13272 * data/yacc.c: Let $$ and @$ in %initial-action designate the
13273 look-ahead.
13274 Push them in the stacks.
13275 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
13276
13277 2004-09-20 Akim Demaille <akim@epita.fr>
13278
13279 * doc/bison.texinfo (Initial Action Decl): New.
13280
13281 2004-09-20 Akim Demaille <akim@epita.fr>
13282
13283 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
13284 clearer criterion to define it.
13285 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
13286 When reducing on an empty RHS, use the latest stacked location as
13287 location.
13288 yylloc is not always available.
13289 * data/glr.c: Likewise.
13290 Also, honor initial-actions.
13291
13292 2004-09-20 Akim Demaille <akim@epita.fr>
13293
13294 * data/yacc.c (YY_LOCATION_PRINT): New.
13295 Define when we know YYLTYPE's structure, i.e., when the default
13296 YYLLOC_DEFAULT is used.
13297 * data/c.m4 (b4_yysymprint_generate): Use it.
13298 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
13299 value of the result.
13300 (error_start_): Replace with...
13301 (error_range_): this location array.
13302 This allows to replace code relying on the implementation of
13303 locations by portable code.
13304 * data/yacc.c (yylerrsp): Replace with...
13305 (yyerror_range): this.
13306 Every time a token is popped, update yyerror_range[0], to have an
13307 accurate location for the error token.
13308 * data/glr.c (YY_LOCATION_PRINT): New.
13309 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
13310 deference a pointer.
13311 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
13312 report the location in %printers.
13313
13314 * src/scan-skel.l: Instead of abort, report error messages to ease
13315 understanding skeleton scanning failures.
13316
13317 2004-09-16 Akim Demaille <akim@epita.fr>
13318
13319 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
13320 (iterator, const_iterator): these, to be more in the C++ spirit.
13321 Also, return reverse iterators so that when displaying the stack
13322 we display its bottom first.
13323 (Parser::stack_print_, Parser::reduce_print_): Match the messages
13324 from yacc.c.
13325 We should probably use vector here though.
13326
13327 2004-09-16 Akim Demaille <akim@epita.fr>
13328
13329 Have more complete shift traces.
13330
13331 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
13332 to report Shifts instead of ad hoc YYDPRINTF invocations,
13333 including for the error token.
13334 * data/lalr1.cc (symprint_): Output the location.
13335 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
13336 output the location within the %printer.
13337 Activate GLR tests, at least to make sure they compile properly.
13338 They still don't pass though.
13339 * tests/calc.at: Adjust expect verbose output, since now "Entering
13340 state..." is on a different line than the "Shifting" message.
13341
13342 2004-09-08 Akim Demaille <akim@epita.fr>
13343
13344 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
13345 Bison directive from the Bison file to the invocation of this
13346 macro, so that these directives are passed to
13347 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
13348 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
13349 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
13350 the extra Bison directives instead of the whole series.
13351 Change the grammar so that there are recoverable errors, and
13352 unrecoverable errors. Now we can have the parser give up before
13353 consuming the whole input. As a result we now can observe that
13354 the lookahead is freed when needed.
13355 Change the parser source to parse argv[1] instead of a hard coded
13356 string.
13357 Simplify yylex, and give a value and location to EOF.
13358 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
13359 passed directives already coded in the file.
13360 Add some tests to check the location of "error".
13361 For some tests, the C++ parser is correct, and not yacc.c.
13362 For other tests, they provide different, but unsatisfying, values,
13363 so keep the C++ value so that at least one parser is "correct"
13364 according to the test suite.
13365 (Actions after errors): Remove, this is subsumed by the
13366 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
13367
13368 2004-09-06 Akim Demaille <akim@epita.fr>
13369
13370 * data/lalr1.cc: Adjust the indentation of the labels.
13371 (Parser::pop): New.
13372 Use it.
13373
13374 2004-09-06 Akim Demaille <akim@epita.fr>
13375
13376 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
13377 argument, an informative message.
13378 Call YY_SYMBOL_PRINT.
13379 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
13380 * data/lalr1.cc (destruct_): Likewise.
13381 In addition, no longer depend on b4_yysymprint_generate and
13382 b4_yydestruct_generate to generate these functions, do it "by
13383 hand".
13384
13385 2004-09-03 Akim Demaille <akim@epita.fr>
13386
13387 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
13388 invoked, yydestruct the lookahead.
13389 * tests/calc.at (Calculator $1): Update the expected lengths of
13390 traces: there is an added line for the discarded lookahead.
13391 * doc/bison.texinfo (Destructor Decl): Some rewording.
13392 Define "discarded" symbols.
13393
13394 2004-09-02 Akim Demaille <akim@epita.fr>
13395
13396 * data/lalr1.cc (translate_, destruct_): No reason to be static.
13397
13398 2004-09-02 Akim Demaille <akim@epita.fr>
13399
13400 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
13401 (YYDSYMPRINTF): Rename as...
13402 (YY_SYMBOL_PRINT): this.
13403 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
13404 two.
13405 Use it instead of direct symprint_ calls.
13406 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
13407 one.
13408
13409 2004-09-02 Akim Demaille <akim@epita.fr>
13410
13411 * data/lalr1.cc (b4_yysymprint_generate): New.
13412 (symprint_): New member function, defined when YYDEBUG.
13413 Use it consistently instead of token/nterm debugging output by
13414 hand.
13415 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
13416 %printer calls to use cdebug_ when using lalr1.cc.
13417
13418 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
13419
13420 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
13421 with #ifdef YYDEBUG.
13422
13423 2004-08-26 Akim Demaille <akim@epita.fr>
13424
13425 * doc/bison.texinfo (Implementing Loops): Rename as...
13426 (Implementing Gotos/Loops): this.
13427
13428 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
13429
13430 Adjust to latest gnulib.
13431 * bootstrap (gnulib_modules): Add xalloc-die.
13432 Set LC_ALL=C so that file names sort consistently.
13433 Prefer the gnulib copies of gettext.m4, glibc21.m4,
13434 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
13435 uintmax_t.m4, ulonglong.m4.
13436 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
13437 po.m4 since we are now using _gl.m4 instead.
13438
13439 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
13440
13441 * src/scan-action.l: Remove. Scanning of semantic actions is
13442 handled in scan-gram.l.
13443
13444 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
13445
13446 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
13447
13448 * src/location.h (struct): The file member is a uniqstr.
13449 (equal_boundaries): Use UNIQSTR_EQ for comparison.
13450
13451 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
13452
13453 Fix bug with non-%union parsers that have printers or destructors,
13454 which led to a Bison core dump. Reported by Peter Fales in
13455 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
13456
13457 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
13458 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
13459 not to our own type.
13460 * src/output.c (symbol_destructors_output, symbol_printers_output):
13461 Don't assume %union.
13462 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
13463 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
13464 UNION-FLAG. All callers changed.
13465 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
13466 Use type char, not unsigned int, when declaring an array of char;
13467 this lets us remove a cast.
13468 (Printers and Destructors): Add non-%union test cases.
13469
13470 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
13471
13472 * doc/bison.texinfo: Minor editorial changes, mostly to the new
13473 GLR writeups. E.g., avoid frenchspacing and the future tense,
13474 change "lookahead" to "look-ahead", and change "wrt" to "with
13475 respect to".
13476
13477 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
13478
13479 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
13480 New sections, split off from the GLR Parsers section. Put the new
13481 Simple GLR Parser near the start of the GLR section, for clarity.
13482 Rewrite connective text.
13483
13484 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
13485
13486 * doc/bison.texinfo (Simple GLR Parsers): New section.
13487
13488 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>

13490 * NEWS, TODO, doc/bison.texinfo:
13491 Use "look-ahead" instead of "lookahead", to be consistent.
13492 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
13493 while we're fixing "look-ahead".
13494 * src/conflicts.c (shift_set): Renamed from shiftset.
13495 (look_ahead_set): Renamed from lookaheadset.
13496 * src/print.c: Likewise.
13497 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
13498 name for "lookahead".

13516
13517 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
13518
13519 Don't assume the C++ compiler takes the same arguments as the C compiler
13520 (trivial change).
13521 * configure.ac (O0CXXFLAGS): New var.
13522 * tests/atlocal.in (CXXFLAGS): Use it.
13523
13524 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

13529
13530 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
13531 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13532 Output to a .cc file for C++, not to a .c file.
13533 * tests/calc.at (AT_CHECK_CALC): Likewise.
13534 * tests/regression.at (AT_CHECK_DANCER): Likewise.
13535 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
13536
13537 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
13538
13539 * tests/calc.at, tests/actions.at: Workaround for SGI
13540 C++ compiler. (trivial change)
13541
13542 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
13543
13544 Spent a few hours checking out which prerequisite versions the
13545 current sources actually require. I went all the way back to
13546 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
13547 a seemingly endless set of combinations of versions more recent
13548 than that. The bottom line is that the current sources require
13549 fairly recent versions of the build tools, and it'll be some work
13550 to change this.
13551 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
13552 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
13553 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
13554 Add comments explaining why those particular versions are
13555 currently needed.
13556
13557 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
13558 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
13559 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
13560
13561 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
13562 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
13563
13564 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13565
13566 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
13567 0.11.5. Suggested by Bruno Haible.
13568 * bootstrap: Remove gettext version checking.
13569
13570 * doc/bison.texinfo (Decl Summary): Also mention that %union
13571 can depend on prerequisite types. Problem reported by Tim
13572 Van Holder.
13573
13574 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13575
13576 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
13577 * README-alpha: Don't tell people not to package this.
13578
13579 * bootstrap: Don't assume $(...) works; use `...` instead.
13580 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
13581 gettext better.
13582
13583 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
13584 put into the -d output file, and mention what to do if YYSTYPE is
13585 defined as a macro.
13586
13587 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13588
13589 Undo change made earlier today: it caused autopoint to not bring
13590 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
13591 autopoint's.
13592
13593 * bootstrap: Check that gettext version matches what's in
13594 configure.ac. Warn users to ignore robots.txt ERROR 404.
13595 * bootstrap: Undo today's earlier change (logged below).
13596 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
13597
13598 The gettext version checking is causing more trouble than it's
13599 curing; remove it. Problem reported by Paul Hilfinger.
13600
13601 * bootstrap: Issue a warning that one can expect a message
13602 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
13603 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
13604
13605 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
13606
13607 Ensure that the C++ compiler used for testing actually works on a
13608 simple test program; if not, skip the C++-related tests. Problem
13609 reported by Vin Shelton in:
13610 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
13611
13612 * m4/cxx.m4: New file.
13613 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
13614 * tests/atlocal.in (BISON_CXX_WORKS): Add.
13615 * tests/local.at (AT_COMPILE_CXX): Use it.
13616
13617 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
13618
13619 * data/glr.c (yylloc): Output this macro even if locations are not
13620 being generated, as the GLR parser needs it even in that case.
13621 Problem reported by Troy A. Johnson
13622 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
13623
13624 * configure.ac (AC_INIT): Update to 1.875e.
13625
13626 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
13627
13628 * NEWS: Version 1.875d.
13629 * configure.ac (AC_INIT): Likewise.
13630 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
13631
13632 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
13633 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
13634 lalr1.cc runs afoul of the first, and the last two are no longer
13635 supported by GCC 3.4.0.
13636 * README: Mention GNU m4 1.4 or later; mention m4 patches.
13637 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
13638
13639 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
13640
13641 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
13642 unsigned int, for compatibility with latest gnulib hash module.
13643 * src/state.c (state_hash, state_hasher): Likewise.
13644 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
13645 * src/uniqstr.c (hash_uniqstr): Likewise.
13646
13647 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13648
13649 * NEWS: Unescaped newlines are no longer allowed in char & strings.
13650
13651 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
13652 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
13653 character and string literals.
13654 (unexpected_end): New function.
13655 (unexpected_eof): Use it.
13656 (unexpected_newline): New function.
13657 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
13658 actions.
13659
13660 * NEWS: Document %expect-rr.
13661
13662 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
13663 Fix typo by replacing $1 with $option.
13664 Remove more 'intl'-related files.
13665 Don't DEFUN AM_INTL_SUBDIR twice.
13666
13667 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
13668 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
13669 strtoul.c.
13670 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
13671 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
13672 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
13673 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
13674 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
13675 * src/.cvsignore: Add *.output.
13676
13677 * src/parse-gram.y: Put copyright notice inside %{ %} so it
13678 gets copied to the output file.
13679
13680 2004-04-28 Paul Eggert <eggert@twinsun.com>
13681
13682 Get files from the gnulib and po repositories, instead of relying
13683 on them being in our CVS. Upgrade to latest versions of gnulib
13684 and Automake.
13685
13686 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
13687 * bootstrap: Bootstrap from gnulib and po repositories.
13688 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
13689 * README-cvs: Document these changes. Remove version numbers from
13690 mentions of build tools, since they change so often. Mention Flex.
13691
13692 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
13693 (gl_USE_SYSTEM_EXTENSIONS): Add.
13694 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
13695 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
13696 does this for us.
13697 (AC_ISC_POSIX): Remove; we no longer support this
13698 ancient OS, as it gets in the way of latest Autoconf & gnulib.
13699 (AC_HEADER_STDC): Remove: we now assume C89 or better.
13700 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
13701 Do not check for C89 headers, except for locale.h which is used
13702 by the Yacc library and must port to K&R hosts.
13703 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
13704 Do not check for C89 functions, except for setlocale which is
13705 used by the Yacc library.
13706 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
13707 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

13710 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
13711 AM_GNU_GETTEXT): Remove; now done by:
13712 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
13713 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
13714 for us.
13715
13716 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
13717 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
13718 Define to empty, as gnulib.mk will do the rest for us.
13719 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
13720 for us.
13721 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
13722 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
13723
13724 * src/files.c: Include gnulib's xstrndup.h.
13725
13726 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
13727 (REALLOC): Use xnrealloc, for likewise.
13728 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
13729 (strnlen, memrchr): Remove decls; functions no longer used.
13730 Include <stpcpy.h>.
13731
13732 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

13752 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
13753 Remove, as these files are now generated automatically
13754 by bootstrap or automake.
13755
13756 * po/ChangeLog: Remove: all but one entry was a duplicate
13757 of this file, and I moved that 2000-11-02 entry here.
13758
13759 * config/.cvsignore: Add Makefile, depcomp, install-sh.

13777
13778
13779 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
13780 support it. (The latest stable gzip doesn't.)
13781
13782 2004-04-27 Paul Eggert <eggert@twinsun.com>
13783
13784 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
13785 case, as stos_ is now used by destructors due to the 2004-02-09
13786 change.
13787
13788 Remove more K&R C support.
13789 * lib/libiberty.y (PARAMS): Remove. All uses removed.

13794 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
13795 unconditionally.
13796 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
13797 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
13798 (strchr, strspn, memchr): Remove decls.
13799 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
13800 unconditionally. Do not declare perror.
13801 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
13802 unconditionally.
13803
13804 * src/complain.c (_): Remove useless defn, as system.h defines this.
13805
13806 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
13807 with latest obstack.h.
13808 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
13809 to procedure types, as obstack.h now does that for us.
13810 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
13811
13812 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
13813 so that this include file can stand alone.
13814 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
13815 does this now. Include subpipe.h first after config.h, to
13816 test whether it can stand alone.
13817
13818 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
13819 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
13820 unused declaration.
13821
13822 * tests/synclines.at (%union synch line): Put a dummy member in
13823 the union, because empty unions aren't allowed in C. Caught
13824 by GCC 3.4.0.
13825
13826 2004-04-13 Jim Meyering <jim@meyering.net>
13827
13828 * src/conflicts.c (conflicts_print): Correct format string typo:

13830
13831 2004-03-30 Paul Eggert <eggert@twinsun.com>
13832
13833 * src/getargs.c (version): Update copyright year to 2004.

13841 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
13842 Likewise.
13843 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,

13872 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
13873
13874 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
13875 (declaration): Replace expected_conflicts with expected_sr_conflicts.
13876 Add %expect-rr rule.
13877
13878 * src/scan-gram.l: Recognize %expect-rr.
13879

13887 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
13888 for GLR parsers.
13889 Use expected_sr_conflicts in place of expected_conflicts.
13890 Warn if expected_rr_conflicts used in non-GLR parser.
13891
13892 * doc/bison.texinfo: Add documentation for %expect-rr.
13893
13894 2004-03-08 Paul Eggert <eggert@gnu.org>
13895
13896 Add support for hex token numbers. Suggested by Odd Arild Olsen in
13897 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
13898
13899 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
13900 in lalr1.cc.
13901 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
13902 * src/scan-gram.l (scan_integer): New function.
13903 ({int}): Use it.
13904 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
13905 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
13906 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
13907 Say "long int", not "long", for uniformity with GNU style.
13908
13909 2004-02-25 Paul Eggert <eggert@twinsun.com>
13910
13911 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
13912 compilers. This fixes a problem with Intel's C++ compiler being
13913 chatty, reported by Guido Trentalancia in
13914 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
13915
13916 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
13917
13918 Support %destructor and merge error locations in lalr1.cc.
13919
13920 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
13921 (Parser::stos_): Define unconditionally.
13922 (Parser::destruct_): New method. Generate its body with
13923 b4_yydestruct_generate.

13925 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
13926 token which are discarded.
13927 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
13928 error_start_ when erroneous token are discarded.
13929 (Parser::parse) <yyerrlab1>: Compute the location of the error
13930 token so that it covers all the discarded tokens.
13931 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
13932 it can be called with `%skeleton "lalr1.cc"', and do that.
13933
13934 2004-02-02 Paul Eggert <eggert@twinsun.com>
13935
13936 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
13937 $(top_srcdir)/lib and ../lib. This fixes a bug reported
13938 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
13939 There's no need to mention top_builddir since Automake does that
13940 for us.
13941 (INCLUDES): Remove, as Automake says it's obsolescent.
13942 Contents migrated into AM_CPPFLAGS as described above.
13943 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
13944
13945 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
13946
13947 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
13948 (yyreportSyntaxError): Handle case where lookahead token is
13949 YYEMPTY.
13950
13951 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13952
13953 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
13954 resulting parsers are compilable with C++.
13955
13956 2003-12-23 Paul Eggert <eggert@twinsun.com>
13957
13958 * config/depcomp, config/install-sh: Sync with Automake 1.8.
13959 * src/output.c (output_skeleton): Rename local var.
13960 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
13961 Bison tokens, as this runs afoul of the 2003-10-07 change that
13962 disallowed NUL bytes in character constants or string literals.
13963
13964 * tests/local.at: Require Autoconf 2.59's Autotest.
13965 * tests/testsuite.at: Don't include local.at, since we now assume
13966 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
13967 including it.
13968 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
13969 multiple inclusion warnings.
13970
13971 2003-12-02 Akim Demaille <akim@epita.fr>
13972

13977 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
13978
13979 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
13980
13981 2003-10-07 Paul Eggert <eggert@twinsun.com>
13982
13983 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
13984 if testsuite doesn't exist.
13985
13986 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
13987 literals, unfortunately.
13988 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
13989 Complain about NUL bytes in character constants or string literals.
13990
13991 2003-10-05 Paul Eggert <eggert@twinsun.com>
13992
13993 * NEWS: Don't document %no-default-prec, as it's still
13994 too experimental.
13995 * doc/bison.texinfo: Document %no-default-prec only if
13996 the defaultprec flag is set. Normally it's not.
13997
13998 2003-10-04 Paul Eggert <eggert@twinsun.com>
13999
14000 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
14001 non-modifiable lvalue, instead of a modifiable one.
14002 * doc/bison.texinfo (Actions): Document that $$ can
14003 be assigned to. Do not claim that $$ and $N are
14004 array element references: user code should not rely on this.
14005
14006 2003-10-01 Paul Eggert <eggert@twinsun.com>
14007
14008 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
14009 (grammar_declaration): Use it.
14010 * src/scan-gram.l: New token %no-default-prec.
14011 * tests/conflicts.at: Revamp tests to use %no-default-prec.
14012 * NEWS, doc/bison.texinfo: Document the above.
14013
14014 2003-10-01 Akim Demaille <akim@epita.fr>
14015
14016 VCG no longer supports long_straight_phase.
14017
14018 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
14019 * src/print_graph.c (print_graph): Adjust.
14020
14021 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
14022 and Paul Eggert <eggert@twinsun.com>
14023

14025 Table of Symbols): Document %default-prec.
14026 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
14027 (grammar_declaration): Set default_prec on %default-prec.
14028 * src/scan-gram.l (%default-prec): New token.
14029 * src/reader.h (default_prec): New flag.
14030 * src/reader.c: Likewise.
14031 (packgram): Handle it.
14032 * tests/conflicts.at (%default-prec without %prec,
14033 %default-prec with %prec, %default-prec 1): New tests.
14034
14035 2003-09-30 Paul Eggert <eggert@twinsun.com>
14036
14037 * tests/testsuite.at: Include local.at, not input.at, fixing
14038 a typo in the 2003-08-25 patch.
14039
14040 2003-08-27 Akim Demaille <akim@epita.fr>
14041
14042 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
14043 GCC warnings.
14044
14045 2003-08-26 Akim Demaille <akim@epita.fr>
14046
14047 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
14048 "<\#" to avoid magic from Gnus when posting parts of this script.
14049
14050 2003-08-26 Akim Demaille <akim@epita.fr>
14051
14052 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
14053 (Parser::parse): here.
14054 Adjust: nerrs and errstatus is now replaced by...
14055 (Parser::nerrs_, Parser::errstatus_): New.
14056
14057 2003-08-25 Akim Demaille <akim@epita.fr>
14058
14059 * config/announce-gen, Makefile.cfg: New.
14060 * Makefile.am: Adjust.
14061 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
14062 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
14063
14064 2003-08-25 Akim Demaille <akim@epita.fr>
14065
14066 When reducing initial empty rules, Bison parser read an initial
14067 location that is not defined. This results in garbage, and that
14068 affects Bison's own parser. Therefore we need (i) to extend Bison
14069 to support a means to initialize this location, and (ii) to use
14070 this CVS Bison to fix CVS Bison's parser.
14071
14072 * src/reader.h, reader.c (epilogue_augment): Remove, replace
14073 with...
14074 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
14075 * src/parse-gram.y: Adjust.
14076 (%initial-action): New.
14077 (%error-verbose): Since we require CVS Bison, there is no reason
14078 not to use it.
14079 * src/scan-gram.l: Adjust.
14080 * src/Makefile.am (YACC): New, to make sure we use our own parser.
14081 * data/yacc.c (yyparse): Use b4_initial_action.
14082
14083 2003-08-25 Akim Demaille <akim@epita.fr>
14084
14085 * doc/bison.texinfo: Don't promote stdout for error messages.
14086
14087 2003-08-25 Akim Demaille <akim@epita.fr>
14088
14089 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
14090 From Alexandre Duret-Lutz.
14091
14092 2003-08-25 Akim Demaille <akim@epita.fr>
14093
14094 Version 1.875c.

14096 2003-08-25 Akim Demaille <akim@epita.fr>
14097
14098 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
14099 Use them.
14100
14101 2003-08-25 Akim Demaille <akim@epita.fr>
14102
14103 * data/lalr1.cc (Parser::reduce_print_): New.
14104 Use it.
14105
14106 2003-08-25 Akim Demaille <akim@epita.fr>
14107
14108 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
14109 error recovery loops. This patch is based on
14110 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
14111 Also, augment the similarity between lalr1.cc and yacc.c.
14112 Note: the locations of error recovery rules are not correct yet.
14113
14114 * data/lalr1.cc: Comment changes to augment the similarity between
14115 lalr1.cc and yacc.c.
14116 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
14117 (yyerrlab1): Remove, but where it used to be (now the bottom part of
14118 yyerrlab), when hitting EOF, pop the whole stack here instead of
14119 merely falling thru the default error handling mechanism.
14120 (yyerrorlab): New label, with the old contents of YYERROR,
14121 plus the following change: pop the stack of rhs corresponding
14122 to the production that invoked YYERROR. That is how Yacc
14123 behaves (required by POSIX).
14124 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
14125 fail.
14126
14127 2003-08-25 Akim Demaille <akim@epita.fr>
14128
14129 Tune local.at so that people can "autom4te -l autotest calc.at -o
14130 calc" for instance, to extract a sub test suite.
14131
14132 * tests/testsuite.at: Move the initialization, Autotest version
14133 requirement, and AT_TESTED invocation into...
14134 * tests/local.at: here.
14135 * tests/testsuite.at: Include it for compatibility with Autoconf
14136 2.57.
14137 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
14138 be ignore.
14139
14140 2003-08-04 Paul Eggert <eggert@twinsun.com>
14141
14142 Rework code slightly to avoid gcc -Wtraditional warnings.
14143 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
14144 The returned value is now stored in *YY0. All callers changed.
14145 * src/output.c (merge_output): Adjust to the above change.
14146
14147 2003-07-26 Paul Eggert <eggert@twinsun.com>
14148
14149 * data/glr.c (YYASSERT): New macro.
14150 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
14151 yyresolveStates, yyprocessOneStack):
14152 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
14153 Derived from a suggestion by Frank Heckenbach.
14154
14155 2003-07-25 Paul Eggert <eggert@twinsun.com>
14156
14157 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
14158 for portability to K&R C (after ansi2knr, presumably). See
14159 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
14160 by Frank Heckenbach, though I have omitted the structure-initialization
14161 part of his glr-knr.diff patch since I recall that the Portable
14162 C Compiler didn't require that change.
14163
14164 Let the user specify how to allocate and free memory.
14165 Derived from a suggestion by Frank Heckenbach in
14166 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
14167 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
14168 All uses of free, malloc, realloc changed to use these macros,
14169 and unnecessary casts removed.
14170 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
14171
14172 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
14173
14174 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
14175 use s.empty() rather than s == "" to test for empty string; see
14176 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>

14186 and return properly parenthesized result.
14187 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
14188 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
14189 Remove unnecessary parentheses from uses.

14196 yyreportTree): Do not assume that size_t is the same width as int,
14197 when printing sizes. Print sizes using an unsigned format.
14198 Problem reported by Frank Heckenbach in
14199 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
14200
14201 Port to Forte Developer 7 C compiler.
14202 * data/glr.c (struct YYLTYPE): If locations are not being used,
14203 declare a single dummy member, as empty structs do not conform
14204 to the C standard.
14205 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
14206 the Forte Developer 7 C compiler complains that end-of-loop
14207 code is not reached.
14208
14209 2003-06-17 Paul Eggert <eggert@twinsun.com>
14210
14211 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
14212 avoid warnings from picky compilers about redefinition of PARAMS.
14213
14214 2003-06-17 Paul Eggert <eggert@twinsun.com>
14215
14216 Version 1.875b.
14217
14218 * NEWS: Document 1.875b.
14219
14220 * lib/bbitset.h: Do not include config.h; that's the includer's job.
14221 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
14222 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
14223 Don't use 'index' in comments, as it's a builtin fn on some hosts.
14224 * lib/bitset_stats.c: Include gettext.h unconditionally, as
14225 per recent gettext manual's suggestion.
14226 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
14227 Use prototypes, not old-style definitions.
14228 * lib/lbitset.c (lbitset_unused_clear): Likewise.
14229 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
14230 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
14231 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

14241 (ATTRIBUTE_UNUSED): Define unconditionally.
14242
14243 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
14244 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
14245 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
14246 * lib/vbitset.c, lib/vbitset.h: New files.
14247 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
14248 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
14249 from libbitset.
14250
14251 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
14252 `How Can I Reset @code{yyparse}', since texinfo does not allow
14253 arbitrary @ in node names.
14254
14255 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
14256 shouldn't be needed according to the gettext 0.12.1 documentation
14257 but which seem to be needed anyway: codeset.m4 glibc21.m4
14258 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
14259 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
14260 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.

14263 * m4/.cvsignore: Add nls.m4, po.m4.
14264
14265 Upgrade to CVS gnulib.
14266 * stdbool_.h: File renamed from stdbool.h.in.
14267 * configure.ac (AM_STDBOOL_H): Invoke this instead of
14268 AC_HEADER_STDBOOL.
14269 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
14270 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
14271 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
14272 (MOSTLYCLEANFILES): New var.
14273 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
14274 (stdbool.h): New rule.
14275 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
14276 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
14277 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
14278 m4/quote.m4: Upgrade to today's gnulib.
14279
14280 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
14281 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
14282 the tests right now.
14283 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
14284 yyerror are declared before use; C99 requires this.
14285
14286 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14287
14288 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
14289 first.
14290 (yyrecoverSyntaxError): Correct the logic for setting and testing
14291 yyerrState.
14292 Correct comment on handling EOF.
14293 Allow states with only a default reduction, rather than failing
14294 (I can't quite reconstruct why these were not allowed before).
14295
14296 Fixes to avoid problem that $-N rules in GLR parsers can cause
14297 buffer overruns, corrupting state.
14298
14299 * src/output.c (prepare_rules): Output max_left_semantic_context
14300 definition.
14301 * src/reader.h (max_left_semantic_context): New variable declaration.
14302 * src/scan-gram.l (max_left_semantic_context): Define.
14303 (handle_action_dollar): Update max_left_semantic_context.
14304 * data/glr.c (YYMAXLEFT): New definition.
14305 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
14306 (yyresolveAction): Ditto.
14307
14308 Fixes to problems with location handling in GLR parsers reported by
14309 Frank Heckenbach (2003/06/05).
14310
14311 * data/glr.c (YYLTYPE): Make trivial if locations not used.
14312 (YYRHSLOC): Add parentheses, and define only if locations used.
14313 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
14314 locations not used.
14315 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
14316 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
14317
14318 * tests/cxx-type.at: Exercise location information; update tests
14319 to differentiate output with and without locations.
14320 Remove forward declarations of yylex and yyerror---caused errors
14321 because default YYLTYPE not yet defined.
14322 Change semantic actions to compute strings, rather than printing
14323 them directly (to test proper passing of semantics values). Change
14324 output to prefix notation and update test data and expected results.
14325 (yylex): Track locations.
14326 (stmtMerge): Return value rather than printing, and include arguments
14327 in value.
14328
14329 2003-06-03 Paul Eggert <eggert@twinsun.com>
14330
14331 Avoid warnings generated by GCC 2.95.4 when Bison is
14332 configured with --enable-gcc-warnings.
14333 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
14334 yy::]b4_parser_class_name[::translate_,
14335 yy::Stack::operator[] (unsigned),
14336 yy::Stack::operator[] (unsigned) const,
14337 yy::Slice::operator[] (unsigned),
14338 yy::Slice::operator[] (unsigned) const):
14339 Rename local vars to avoid warnings.
14340 * tests/glr-regression.at (Improper handling of embedded actions
14341 and $-N in GLR parsers): Remove unused local variable from yylex.
14342 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
14343 (void) as arg when not pure, since we now assume C89 when building
14344 Bison. Pacify GCC by using parameter.
14345
14346 2003-06-02 Paul Eggert <eggert@twinsun.com>
14347
14348 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
14349 yy::Location::lines, yy::Location::columns): Rename arguments
14350 to avoid shadowing; this removes a warning generated by GCC 3.3.
14351
14352 2003-06-01 Paul Eggert <eggert@twinsun.com>
14353
14354 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
14355 to g++, as GCC 3.3 complains if you do it.
14356 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
14357 everything that WARNING_CFLAGS has, except omit warnings
14358 not suitable for C++.
14359 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
14360 * tests/atlocal.in (CXXFLAGS): New var.
14361 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
14362
14363 Fix a GLR parser bug I reported in February; see
14364 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
14365 The problem was that GLR parsers did not conform to the C standard,
14366 because actions like { $1 = $2 + $3; } expanded to expressions
14367 that invoked YYFILL in separate subexpressions, and YYFILL assigned
14368 to a local variable. The C standard says that expressions
14369 like (var = f ()) + (var = f ()) have undefined behavior.
14370 Another problem was that GCC sometimes issues warnings that
14371 yyfill and its parameters are unused.
14372
14373 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
14374 as possibly unused.
14375 (yyfill): New function.
14376 (YYFILL): Use it.
14377 (yyuserAction): Change type of yynormal to bool, so that it matches
14378 the new yyfill signature. Mark it as possibly unused.
14379
14380
14381 Follow up on a bug I reported in February, where a Bison-generated
14382 parser can loop. Provide a test case and a fix for yacc.c. I
14383 don't have a fix for lalr1.cc or for glr.c, unfortunately.
14384 The original bug report is in:
14385 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
14386
14387 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
14388 macro's size was becoming unwieldy.
14389 (yyerrlab): Do not discard an empty lookahead symbol, as this
14390 might destroy garbage.
14391 (yyerrorlab): New label, with the old contents of YYERROR,
14392 plus the following change: pop the stack of rhs corresponding
14393 to the production that invoked YYERROR. That is how Yacc
14394 behaves, and POSIX requires this behavior.
14395 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
14396 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
14397 Define 'alarm' to do nothing if unistd.h is not available.
14398 Add a new rule "exp: '-' error;" to test the above change to
14399 data/yacc.c. Use 'alarm' to abort any test taking longer than
14400 10 seconds, as it's probably looping.
14401 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
14402 Also, the new yacc.c generates two fewer diagnostics for an
14403 existing test.
14404
14405 2003-05-24 Paul Eggert <eggert@twinsun.com>
14406
14407 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
14408 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
14409 This fixes a problem reported by John Bowman when the Compaq/HP
14410 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
14411 -ansi -Wall -gall).
14412 * data/yacc.c (union yyalloc): Likewise.
14413 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
14414
14415 Switch from 'int' to 'bool' where that makes sense.

14420 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
14421 Return or accept bool, not int. All callers changed.

14428 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
14429 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
14430 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
14431 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
14432 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
14433 bitset_stats_or_and_cmp): Likewise.
14434 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
14435 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
14436 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
14437 ebitset_xor_cmp): Likewise.
14438 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
14439 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
14440 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
14441 lbitset_xor_cmp): Likewise.
14442 * lib/bbitset.h: Include <stdbool.h>.
14443 (struct bitset_vtable): The following members now return bool, not
14444 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
14445 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
14446 or_and_cmp).
14447 * src/conflicts.c (count_rr_conflicts): Likewise.
14448 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
14449 All uses changed.
14450 * lib/ebitset.c (ebitset_obstack_init): Likewise.
14451 * lib/lbitset.c (lbitset_obstack_init): Likewise.
14452 * src/getargs.c (debug_flag, defines_flag, locations_flag,
14453 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
14454 graph_flag): Likewise.
14455 * src/getargs.h (debug_flag, defines_flag, locations_flag,
14456 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
14457 graph_flag): Likewise.

14465 * src/nullable.c (nullable_compute): Likewise.
14466 * src/print.c (print_reductions): Likewise.

14469 * src/output.c (prepare): Use it.
14470 * src/output.c (token_definitions_output,
14471 symbol_destructors_output, symbol_destructors_output): Use string,
14472 not boolean integer, to keep track of whether to output separator.
14473 * src/print_graph.c (print_core): Likewise.
14474 * src/state.c (state_rule_lookaheads_print): Likewise.
14475

14477
14478 2003-05-14 Paul Eggert <eggert@twinsun.com>
14479
14480 * src/parse-gram.y (rules_or_grammar_declaration): Require a
14481 semicolon after a grammar declaration, in the interest of possible
14482 future changes to the Bison input language.
14483 Do not allow a stray semicolon at the start of the grammar.
14484 (rhses.1): Allow one or more semicolons after any rule, including
14485 just before "|" as required by POSIX.
14486 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
14487 grammar.
14488
14489 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
14490
14491 %parse-param support for lalr1.cc.
14492
14493 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
14494 b4_cc_constructor_calls, b4_cc_constructor_call,
14495 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
14496 definitions.
14497 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
14498 parse-param arguments.
14499 (yy::b4_parser_class_name): Declare instance variables to
14500 hold parse-param arguments.
14501 * tests/calc.at: s/value/semantic_value/ because value clashes
14502 with a member of yy::b4_parser_class_name. Adjust C++ code
14503 to handle %parse-param. Enable %parse-param test in C++.
14504
14505 2003-05-12 Paul Eggert <eggert@twinsun.com>
14506
14507 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
14508 English a bit. Fix fclose typo. Change "const char" to "char
14509 const", and use ANSI C rather than K&R for "main". Suggest
14510 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
14511 and suggest yy_switch_to_buffer.
14512
14513 2003-05-05 Paul Eggert <eggert@twinsun.com>
14514
14515 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
14516 C89. This avoids a diagnostic on compilers that define __STDC__
14517 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
14518 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
14519
14520 2003-05-03 Paul Eggert <eggert@twinsun.com>
14521
14522 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
14523 Do not overrun array bounds.
14524 This should fix a bug reported today by Olatunji Oluwabukunmi in
14525 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
14526
14527 2003-04-29 Akim Demaille <akim@epita.fr>
14528
14529 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
14530 * src/getargs.c, src/getargs.h: here, as bool, not int.
14531 (nondeterministic_parser): New.
14532 * src/parse-gram.y, src/scan-gram.l: Support
14533 %nondeterministic-parser.
14534 * src/output.c (prepare): Use nondeterministic_parser instead
14535 of glr_parser where appropriate.
14536 * src/tables.c (conflict_row, action_row, save_row)
14537 (token_actions, token_actions, pack_vector): Ditto.
14538
14539 2003-04-29 Akim Demaille <akim@epita.fr>

14542
14543 2003-04-29 Akim Demaille <akim@epita.fr>
14544
14545 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
14546 with %pure-parser and %locations to exercise the patch from Yakov
14547 Markovitch below.
14548
14549 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
14550
14551 * data/yacc.c: (b4_lex_param): Corrected for the case where
14552 %lex-param is provided and %pure-parser isn't.
14553
14554 2003-04-27 Paul Eggert <eggert@twinsun.com>
14555
14556 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
14557 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
14558 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
14559 if it is not defined.
14560 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.

14562 2003-04-26 Paul Eggert <eggert@twinsun.com>
14563
14564 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
14565 Declare to be of type suitable for the ninf value itself, not of
14566 type suitable for the corresponding table, since the latter might
14567 be unsigned but the ninf value might be negative. This fixes a
14568 bug reported by Alexandre Duret-Lutz in
14569 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
14570
14571 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
14572 invokes it. We shouldn't invoke it twice because it will attempt
14573 to put error.o in the archive twice. This fixes a glitch reported
14574 by Martin Mokrejs in
14575 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
14576
14577 2003-04-21 Paul Eggert <eggert@twinsun.com>
14578
14579 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
14580 to gnulib.
14581
14582 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
14583
14584 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
14585 Fix obvious typo that results in uncompilable GLR parsers
14586 when both %pure-parser and %locations are used. (trivial change)
14587
14588 2003-04-17 Paul Eggert <eggert@twinsun.com>
14589
14590 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
14591 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
14592 Do not insert the expected token via unput, as this runs afoul
14593 of a POSIX-compatibility bug in flex 2.5.31.
14594 All uses changed to BEGIN the parent state,
14595 since we no longer insert the expected token via unput.
14596 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
14597 that is no longer emitted after the above change.
14598
14599 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
14600 the first one. This change is from Paul Hilfinger, and it fixes
14601 regression reported by Werner Lemberg in
14602 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
14603
14604 (resolve_sr_conflict): Don't invoke state_errs_set
14605 unless one or more tokens have been explicitly made errors.
14606 Otherwise, the above change causes Bison to abort.
14607
14608 * tests/existing.at (GNU pic Grammar): New test case, taken from
14609 Lemberg's email.
14610
14611 2003-03-31 Akim Demaille <akim@epita.fr>
14612
14613 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
14614
14615 2003-03-31 Akim Demaille <akim@epita.fr>
14616
14617 * src/output.c (prepare_symbols): Avoid trailing spaces in the
14618 output.
14619
14620 2003-03-31 Akim Demaille <akim@epita.fr>
14621
14622 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
14623 From Paul Hilfinger.
14624
14625 2003-03-29 Akim Demaille <akim@epita.fr>
14626
14627 * m4/error.m4: Do not put under dynamic conditions some code which
14628 expansion is under static control.
14629
14630 2003-03-29 Akim Demaille <akim@epita.fr>
14631
14632 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
14633
14634 2003-03-29 Akim Demaille <akim@epita.fr>
14635
14636 * doc/bison.texinfo (Strings are Destroyed): New.
14637
14638 2003-03-13 Paul Eggert <eggert@twinsun.com>
14639
14640 * .cvsignore: Add configure.lineno.
14641 * src/.cvsignore: Add yacc.
14642 * tests/.cvsignore: Add testsuite.log.
14643 * doc/fdl.texi: Sync with latest FSF version.
14644
14645 2003-03-12 Paul Eggert <eggert@twinsun.com>
14646
14647 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
14648 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
14649 cursor, instead of leaving it undefined. This fixes a bug
14650 reported by Tim Van Holder in
14651 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
14652 * tests/input.at (Torturing the Scanner): Test the scanner on
14653 an empty input file, which was Tim Van Holder's test case.
14654
14655 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
14656 <sys/resource.h> can be included, include sys/time.h and
14657 sys/times.h first, if available. This works around the SunOS
14658 4.1.4 porting bug reported by Bruce Becker in
14659 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
14660
14661 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
14662 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
14663 AC_HEADER_SYS_WAIT.
14664
14665 Merge changes from gnulib. This was prompted because the CVS
14666 snapshot didn't build on Solaris 7 due to strnlen problems.
14667
14668 These changes need to be merged back into gnulib:
14669 * lib/hash.c: Include <stdbool.h> unconditionally.
14670 * m4/onceonly.m4 (m4_quote): New macro.
14671 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
14672 Quote AC_FOREACH variable-expansions properly.
14673 The 2003-01-03 obstack.h change also needs merging.
14674 {end of changes requiring merging}
14675
14676 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
14677 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

14680 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
14681 New files, imported from gnulib.
14682 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
14683 above.
14684
14685 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
14686 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
14687 gnulib sources.
14688
14689 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
14690 Add.
14691 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
14692 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
14693 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).

14697 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
14698 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
14699 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
14700 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
14701 (jm_PREREQ_ARGMATCH): Remove.

14703 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
14704
14705 * src/system.h: Include <stdbool.h> unconditionally.
14706
14707 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
14708 assuming at least C89 in the bitset code for some time now.
14709
14710 2003-03-03 Akim Demaille <akim@epita.fr>
14711
14712 * ro.po: New.
14713
14714 2003-03-02 Akim Demaille <akim@epita.fr>
14715
14716 * doc/bison.texinfo (Table of Symbols): Reactivate the
14717 documentation for %lex-param, and %parse-param.
14718
14719 2003-03-02 Akim Demaille <akim@epita.fr>
14720
14721 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
14722 generate verbose error messages.
14723 Use the number of tokens as an upper bound in yytname, as it
14724 cannot be a non terminal.
14725
14726 2003-03-02 Akim Demaille <akim@epita.fr>
14727
14728 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
14729 message.
14730
14731 2003-03-02 Akim Demaille <akim@epita.fr>
14732
14733 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
14734 Use them to exercise yycheck overrun.
14735 Based on Andrew Suffield's grammar.
14736
14737 2003-03-02 Akim Demaille <akim@epita.fr>
14738
14739 Create tests/local.at for Bison generic testing macros.
14740
14741 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
14742 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
14743 This new file.
14744 * tests/calc.at (AT_CHECK_CALC): Adjust.
14745 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
14746 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
14747 * tests/local.at: here.
14748 (AT_COMPILE_CXX): Tags the tests using it as c++.
14749 Ignore the test if CXX is not functional.
14750
14751 2003-03-01 Paul Eggert <eggert@twinsun.com>
14752
14753 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
14754 not loc->end, since loc->end might contain garbage and this leads
14755 to undefined behavior on some platforms.
14756 (id_loc, token_start): Use (IF_LINTed) initial values that do not
14757 depend on *loc, so that the reader doesn't give the the false
14758 impression that *loc is initialized.
14759 (<INITIAL>"%%"): Do not bother setting code_start, since its value
14760 does not survive the return.
14761
14762 2003-03-01 Akim Demaille <akim@epita.fr>
14763
14764 * src/scan-gram.l (code_start): Always initialize it when entering
14765 into yylex, as SC_EPILOGUE is activated *before* the corresponding
14766 yylex invocation. An alternative would be making it static, but
14767 then it starts with the second %%'s beginning, instead of its end.
14768
14769 2003-02-28 Paul Eggert <eggert@twinsun.com>
14770
14771 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
14772 around a UnixWare 7.1.1 porting bug reported by John Hughes in
14773 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
14774
14775 2003-02-26 Paul Eggert <eggert@twinsun.com>
14776
14777 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
14778 Remove Sequent/Pyramid discussion (nobody uses them any more).
14779 Merge VMS and MS-DOS discussion; these ports may well be dead
14780 but let's keep mentioning them for now. Put <> around email
14781 addresses. Add copyright notice.
14782
14783 2003-02-24 Paul Eggert <eggert@twinsun.com>
14784
14785 * data/glr.c (yy_reduce_print): yylineno -> yylno,
14786 to avoid collision with flex use of yylineno.
14787 Problem reported by Bruce Lilly in
14788 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

14794 2003-02-21 Akim Demaille <akim@epita.fr>
14795
14796 * data/lalr1.cc: Use temporary variables instead of casts to
14797 change integer types.
14798 Suggested by Paul Eggert.
14799
14800 2003-02-21 Akim Demaille <akim@epita.fr>
14801
14802 * doc/bison.texinfo: Use "location" consistently to refer to @n,
14803 to avoid confusions with lalr1.cc's notion of Position.
14804 Suggested by Paul Eggert.
14805
14806 2003-02-20 Akim Demaille <akim@epita.fr>
14807
14808 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
14809 before initial_columns.
14810 (location.hh): Use consistent variable names when defining the
14811 operator<<.
14812 Use "last" so that we subtract from Positions, not from unsigned.
14813
14814 2003-02-20 Akim Demaille <akim@epita.fr>
14815
14816 * data/lalr1.cc (position.hh): New subfile, including the extended
14817 and Doxygen'ed documentation of class Position.
14818 (location.hh): Use it.

14825 AT_YACC_IF.
14826 Redefine AT_YYERROR_SEES_LOC_IF using it.
14827 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
14828 not defined.
14829 Don't use the location in yy::Parser::error_ and
14830 yy::Parser::print_ when not %locations.
14831 Activate more lalr1.cc tests.
14832
14833 2003-02-19 Akim Demaille <akim@epita.fr>
14834
14835 * data/lalr1.cc: When displaying a line number, be sure to make it
14836 an int.
14837
14838 2003-02-19 Akim Demaille <akim@epita.fr>
14839

14848 error recovery, mixing with/without pops and discarding of the
14849 lookahead.
14850 Exercise YYERROR.
14851 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
14852
14853 2003-02-17 Paul Eggert <eggert@twinsun.com>
14854
14855 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
14856 * tests/testsuite.at (AT_COMPILE): Use them.
14857 This fixes the testsuite problem reported by Robert Lentz in
14858 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
14859
14860 2003-02-12 Paul Eggert <eggert@twinsun.com>
14861
14862 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
14863 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
14864 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
14865 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
14866 Check for malloc failure, for consistency with yacc.c.
14867 (yytname_size): Remove, for consistency with yacc.c.
14868
14869 The bug still remains in data/lalr1.cc, as I didn't have time
14870 to fix it there.
14871

14894 Adjust the C locations to match those from Emacs: first column is
14895 column 0.
14896 Change all the expected results.
14897 Conform to the GCS: simplify the locations when applicable.
14898 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
14899 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace

14908
14909 2003-02-04 Akim Demaille <akim@epita.fr>
14910
14911 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
14912 Location as is defined.
14913
14914 2003-02-04 Akim Demaille <akim@epita.fr>

14959 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
14960 char * var.
14961 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
14962 uniqstr var.
14963 * src/uniqstr.h: Likewise.
14964
14965 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
14966 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
14967 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
14968 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
14969 param to have same name as that of enum, so that we don't use
14970 "s" to stand for a non-state.
14971
14972 2003-02-02 Akim Demaille <akim@epita.fr>
14973
14974 * src/scan-skel.l: Scan more than one inert character per yylex
14975 invocation.
14976
14977 2003-02-01 Paul Eggert <eggert@twinsun.com>
14978
14979 Version 1.875a.
14980
14981 * po/LINGUAS: Add ms.
14982
14983 2003-01-30 Akim Demaille <akim@epita.fr>
14984
14985 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
14986
14987 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14988
14989 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
14990 of $1.
14991
14992 Changes in response to error report by S. Eken: GLR mode does not
14993 handle negative $ indices or $ indices in embedded rules correctly.
14994 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
14995
14996 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
14997 (b4_rhs_location): Ditto.
14998 (yyfill): New function to copy from stack tree into array
14999 incrementally.
15000 (yyuserAction): Modify to allow incremental move of semantic values
15001 to rhs array when in GLR mode.
15002 Define YYFILL to use in user-defined actions to fill semantic array
15003 as needed.
15004 Remove dummy use of yystack, as there is now a guaranteed use.
15005 (yydoAction): Modify to allow incremental move of semantic values
15006 to rhs array when in GLR mode.
15007 (yyresolveAction): Ditto.
15008 (yyglrShiftDefer): Update comment.
15009 (yyresolveStates): Use X == NULL for pointers, not !X.
15010 (yyglrReduce): Ditto.
15011 (yydoAction): Ditto
15012
15013 * tests/glr-regr1.at: Rename to ...
15014 * tests/glr-regression.at: Add new regression test for the problems
15015 described above (adapted from S. Eken).
15016 Update copyright notice.
15017 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
15018 * tests/Makefile.am: Ditto.
15019
15020 2003-01-28 Paul Eggert <eggert@twinsun.com>
15021
15022 * data/lalr1.cc: Do not use @output_header_name@ unless
15023 b4_defines_flag is set. This fixes two bugs reported by
15024 Tim Van Holder in
15025 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
15026 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
15027
15028 2003-01-21 Paul Eggert <eggert@twinsun.com>
15029
15030 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
15031 we don't need to worry about yyerrlab1 being reported as an
15032 "unused label" by non-GCC C compilers. The downside is that if
15033 locations are used then a couple of statements are duplicated each
15034 time YYERROR is invoked, but the upside is that the warnings
15035 should vanish.
15036 (yyerrlab1): Move code to YERROR.
15037 (yyerrlab2): Remove. Change uses back to yyerrlab1.
15038 This reverts some of the 2002-12-27 change.
15039
15040 2003-01-17 Paul Eggert <eggert@twinsun.com>
15041
15042 * src/output.c (symbol_printers_output): Fix typo that led
15043 to core dump. Problem reported by Antonio Rus in
15044 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
15045
15046 2003-01-13 Akim Demaille <akim@epita.fr>,
15047 Quoc Peyrot <chojin@lrde.epita.fr>,
15048 Robert Anisko <anisko_r@lrde.epita.fr>
15049
15050 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
15051 when the stacks contain one element, as the loop would otherwise
15052 free the last state, and then use the top state (the one we just
15053 popped). This means that the initial elements will not be freed
15054 explicitly, as is the case in yacc.c; it is not a problem, as
15055 these elements have fake values.
15056
15057 2003-01-11 Paul Eggert <eggert@twinsun.com>
15058
15059 * NEWS: %expect-violations are now just warnings, reverting
15060 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
15061 bootstrapping problem reported by Matthias Klose; see
15062 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
15063 * src/conflicts.c (conflicts_print): Likewise.
15064 * tests/conflicts.at (%expect not enough, %expect too much,
15065 %expect with reduce conflicts): Likewise.
15066 * doc/bison.texinfo (Expect Decl): Document this. Also mention
15067 that the warning is enabled if the number of conflicts changes
15068 (not necessarily increases).
15069
15070 * src/getargs.c (version): Update copyright year.
15071
15072 2003-01-09 Akim Demaille <akim@epita.fr>
15073
15074 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
15075
15076 2003-01-08 Paul Eggert <eggert@twinsun.com>
15077
15078 * Makefile.maint (WGETFLAGS):
15079 New macro, containing "-C off" to disable proxy caches.
15080 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
15081 (rel-check): Use $(WGET) instead of wget.
15082
15083 2003-01-06 Paul Eggert <eggert@twinsun.com>
15084
15085 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
15086 the GLR paper of Scott, Johnstone and Hussain.
15087
15088 2003-01-04 Paul Eggert <eggert@twinsun.com>
15089
15090 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
15091 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
15092 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
15093 (EXTRA_LIBRARIES): New var, for liby.a.
15094 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
15095 (EXTRA_SCRIPTS): New var, for yacc.
15096
15097 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
15098 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
15099 Problem reported by Nelson H. F. Beebe.
15100
15101 2003-01-03 Paul Eggert <eggert@twinsun.com>
15102
15103 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
15104 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
15105 when compiling Bison 1.875's `bitset bset = obstack_alloc
15106 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
15107
15108 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
15109 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
15110 grow to a huge size with typical invocation.
15111
15112 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
15113 Use the pattern recommended by Autoconf 2.57, except also protect
15114 against double-definition.
15115 * src/system.h: Likewise.
15116 Portability issues reported by Nelson H. F. Beebe.
15117
15118 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
15119 All uses changed. Provide a definition in both C and C++.
15120 (yytrue, yyfalse): Define even if defined (__cplusplus).
15121
15122 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
15123 Reported by Nelson H. F. Beebe.
15124
15125 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
15126
15127 2003-01-02 Paul Eggert <eggert@twinsun.com>
15128
15129 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
15130 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
15131 Bug reported by Nelson H. F. Beebe.
15132
15133 2003-01-01 Paul Eggert <eggert@twinsun.com>
15134
15135 * Version 1.875.
15136
15137 2002-12-30 Paul Eggert <eggert@twinsun.com>
15138
15139 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
15140 Moved here from...
15141 (<INITIAL>","): Here. This causes stray "," to be treated
15142 more uniformly.
15143
15144 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
15145 last brace in braced code when not in Yacc mode, for compatibility
15146 with Bison 1.35. This resurrects the 2001-12-15 patch to
15147 src/reader.c.
15148
15149 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
15150 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
15151
15152 2002-12-28 Paul Eggert <eggert@twinsun.com>
15153
15154 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
15155 that of SYM's type. This fixes Debian bug 168069, reported by
15156 Thomas Olsson.
15157
15158 2002-12-28 Paul Eggert <eggert@twinsun.com>
15159
15160 Version 1.75f.
15161
15162 Switch back to the Yacc style of conflict reports, undoing some
15163 of the 2002-07-30 change.
15164 * doc/bison.texinfo (Understanding): Use Yacc style for
15165 conflict reports. Also, use new way of locating rules.
15166 * src/conflicts.c (conflict_report):
15167 Renamed from conflict_report_yacc, removing the old
15168 'conflict_report'. Translate the entire conflict report at once,
15169 so that we don't assume that "," has the same interpretation in
15170 all languages.
15171 (conflicts_output): Use Yacc-style conflict report for each state,
15172 instead of our more-complicated style.
15173 (conflicts_print): Use Yacc-style conflict report, except print
15174 the input file name when not emulating Yacc.
15175 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
15176 Conflicted Reduction, %expect not enough, %expect too much,
15177 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
15178 * tests/existing.at (GNU Cim Grammar): Likewise.
15179 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
15180
15181 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
15182 fatal): Don't invoke fflush; it's not needed and it might even be
15183 harmful for stdout, as stdout might not be open.
15184 * src/reduce.c (reduce_print): Likewise.
15185
15186 2002-12-27 Paul Eggert <eggert@twinsun.com>
15187
15188 Fix a bug where error locations were not being recorded correctly.
15189 This problem was originally reported by Paul Hilfinger in
15190 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
15191
15192 * data/yacc.c (yyparse): New local var yylerrsp, to record the
15193 top of the location stack's error locations.
15194 (yyerrlab): Set it. When discarding a token, push its location
15195 onto yylerrsp so that we don't lose track of the error's end.
15196 (yyerrlab1): Now is only the target of YYERROR, so that we can
15197 properly record the location of the action that failed. For GCC
15198 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
15199 GCC warning about yyerrlab1 being unused if YYERROR is unused.
15200 (yyerrlab2): New label, which yyerrlab now falls through to.
15201 Compute the error's location by applying YYLLOC_DEFAULT to
15202 the locations of all the symbols that went into the error.
15203 * doc/bison.texinfo (Location Default Action): Mention that
15204 YYLLOC_DEFAULT is also invoked for syntax errors.
15205 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
15206 Error locations include the locations of all the tokens that were
15207 discarded, not just the last token.
15208
15209 2002-12-26 Paul Eggert <eggert@twinsun.com>
15210
15211 * src/files.c: Include quote.h.
15212 (compute_output_file_names): Warn if we detect conflicting
15213 outputs to the same file. This should catch the misunderstanding
15214 exemplified by Debian Bug 165349, reported by Bruce Stephens..
15215
15216 * src/conflicts.c (conflicts_print): If the user specifies
15217 "%expect N", report an error if there are any reduce/reduce
15218 conflicts. This is what the manual says should happen.
15219 This fixes Debian bug 130890, reported by Anthony DeRobertis.
15220 * tests/conflicts.at (%expect with reduce conflicts): New test.
15221
15222 Don't use m4_include on relative file names, as it doesn't work as
15223 desired if there happens to be a file with that name under ".".
15224
15225 * m4sugar/version.m4: Remove; it was included but it wasn't used.
15226 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
15227 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
15228 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
15229 * src/output.c (output_skeleton): Use full path names when
15230 specifying a file to include; don't rely on include path, as
15231 it's unreliable when the working file contains a file with
15232 that name.
15233
15234 2002-12-25 Paul Eggert <eggert@twinsun.com>
15235
15236 Remove obsolete references to bison.simple and bison.hairy.
15237 Problem mentioned by Aubin Mahe in
15238 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
15239 * data/glr.c: Comment fix.
15240 * doc/bison.1: Remove references. Also, mention "yacc".
15241
15242 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
15243 with -g option.
15244
15245 * src/parse-gram.y (declaration): Use enum "report_states" rather
15246 than its numeric value 1.
15247
15248 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
15249 opening a new one. This fixes Debian bug 165349, reported by
15250 Bruce Stephens.
15251
15252 2002-12-24 Paul Eggert <eggert@twinsun.com>
15253
15254 Version 1.75e.
15255
15256 * Makefile.maint (cvs-update): Don't assume that the shell
15257 supports $(...), as Solaris sh doesn't.
15258
15259 * src/parse-gram.y (lloc_default): Remove test for empty
15260 nonterminals at the end, since it didn't change the result.
15261
15262 2002-12-24 Paul Eggert <eggert@twinsun.com>
15263
15264 If the user does not define YYSTYPE as a macro, Bison now declares it
15265 using typedef instead of defining it as a macro. POSIX requires this.
15266 For consistency, YYLTYPE is also declared instead of defined.
15267
15268 %union directives can now have a tag before the `{', e.g., the
15269 directive `%union foo {...}' now generates the C code
15270 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
15271 The default union tag is `YYSTYPE', for compatibility with Solaris 9
15272 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
15273 instead of `yyltype'.
15274
15275 `yystype' and `yyltype' are now obsolescent macros instead of being
15276 typedefs or tags; they are no longer documented and will be
15277 withdrawn in a future release.
15278
15279 * data/glr.c (b4_location_type): Remove.
15280 (YYSTYPE): Renamed from yystype.
15281 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
15282 (struct YYLTYPE): Renamed from struct yyltype.
15283 (YYLTYPE): Renamed from yyltype.
15284 (yyltype, yystype): New (and obsolescent) macros,
15285 for backward compatibility.
15286 * data/yacc.c: Likewise.
15287
15288 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
15289 does not specify a union tag. This is for compatibility with
15290 Solaris 9 yacc.
15291
15292 * src/parse-gram.y (add_param): 2nd arg is now char * not char
15293 const *, since it is now modified by stripping surrounding { }.
15294 (current_braced_code): Remove.
15295 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
15296 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
15297 trailing " {...}". Now of type <chars>.
15298 (grammar_declaration): Adjust to bundled tokens.
15299 (code_content): Remove; stripping is now done by add_param.
15300 (print_token_value): Print contents of bundled tokens.
15301 (token_name): New function.
15302
15303 * src/reader.h (braced_code, current_braced_code): Remove.
15304 (token_name): New decl.
15305
15306 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
15307 token_type, not braced_code code_kind. All uses changed.
15308 (SC_PRE_CODE): New state, for scanning after a keyword that
15309 has (or usually has) an immediately-following braced code.
15310 (token_type): New local var, to keep track of which token type
15311 to return when scanning braced code.
15312 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
15313 <INITIAL>"%parse-param", <INITIAL>"%printer",
15314 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
15315 instead of returning a token type immediately.
15316 (<INITIAL>"{"): Set token type.
15317 (<SC_BRACED_CODE>"}"): Use it.
15318 (handle_action_dollar, handle_action_at): Now returns bool
15319 indicating success. Fail if ! current_rule; this prevents a core dump.
15320 (handle_symbol_code_dollar, handle_symbol_code_at):
15321 Remove; merge body into caller.
15322 (handle_dollar, handle_at): Complain in invalid contexts.
15323
15324 * NEWS, doc/bison.texinfo: Document the above.
15325 * NEWS: Fix years and program names in copyright notice.
15326
15327 2002-12-17 Paul Eggert <eggert@twinsun.com>
15328
15329 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
15330 Reporting, Table of Symbols): Omit mentions of %lex-param and
15331 %parse-param from the documentation for now.
15332
15333 2002-12-15 Paul Eggert <eggert@twinsun.com>
15334
15335 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
15336 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
15337 lookahead symbol, and which sets yychar in parser actions) and it
15338 disagreed with the Bison documentation. Bug
15339 reported by Andrew Walrond.
15340
15341 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
15342 as the caller now does that.
15343 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
15344 (YYEMPTY): Parenthesize right hand side, since others use it.
15345 (yyparse): Don't assume that our generated code is the only code
15346 that sets yychar.
15347
15348 2002-12-13 Paul Eggert <eggert@twinsun.com>
15349
15350 Version 1.75d.
15351
15352 POSIX requires a "yacc" command.
15353 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
15354 (MOSTLYCLEANFILES): Add yacc.
15355 (yacc): New rule.
15356 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
15357 as an alias for bison y.
15358
15359 * po/LINGUAS: Add da.
15360
15361 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
15362 problem with latest <getopt.h>.
15363 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
15364

15380
15381 Remove unportable casts and storage allocation tricks.
15382 While we're at it, remove almost all casts, since they
15383 usually aren't needed and are a sign of trouble.
15384
15385 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
15386
15387 * src/derives.c (derives_compute): Do not subtract NTOKENS from
15388 the pointer DSET returned by malloc; this isn't portable.
15389 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
15390 Similarly for DERIVES.
15391 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
15392 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

15394
15395 * src/derives.c (derives_compute): Do not bother invoking
15396 int_of_rule_number, since rule numbers are integers.
15397
15398 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
15399 rather than XMALLOC (char, N).

15402
15403 * src/gram.h (symbol_number_as_item_number,
15404 item_number_as_symbol_number, rule_number_as_item_number,
15405 item_number_as_rule_number):
15406 Now inline functions rather than macros, to avoid casts.
15407 * src/state.h (state_number_as_int): Likewise.
15408 * src/tables.c (state_number_to_vector_number,
15409 symbol_number_to_vector_number): Likewise.

15412
15413 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
15414 since the resulting storage is always stored into.
15415
15416 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
15417 where it's needed.
15418

15431 symbol_check_alias_consistency_processor, symbol_pack_processor,
15432 symbol_translation_processor, hash_symbol_comparator,
15433 hash_symbol_hasher): Likewise.
15434 * src/uniqstr.c (uniqstr_print_processor): Likewise.
15435 * src/muscle_tab.c (muscles_m4_output):
15436 Use new functions instead of casting old functions unportably.

15439 symbols_token_translations_init):
15440 Likewise.
15441 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
15442
15443 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
15444 var instead of casting to long, to avoid casts.
15445 (prepare_states): Use MALLOC rather than alloca, so that we don't
15446 have to worry about alloca.
15447 * src/state.c (state_hash_lookup): Likewise.
15448
15449 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
15450 local var instead of casting to unsigned char, to avoid casts.
15451
15452 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
15453 STATE_ALLOC): Remove.
15454 (transitions_new, errs_new, reductions_new, state_new): Use malloc
15455 rather than calloc, and use offsetof to avoid allocating slightly
15456 too much storage.
15457 (state_new): Initialize all members.
15458
15459 * src/state.c (state_hash): Use unsigned accumulator, not signed.
15460
15461 * src/symtab.c (symbol_free): Remove; unused.
15462 (symbol_get): Remove cast in lhs of assignment.
15463 (symbols_do): Now static. Accept generic arguments, not
15464 hashing-related ones.
15465
15466 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
15467 (symbol_processor): Remove.
15468 (symbols_do): Remove decl; now static.

15472 (<inttypes.>, <stdint.h>): Include if available.
15473 (uintptr_t): New type, if system lacks it.
15474 (CALLOC, MALLOC, REALLOC): New macros.
15475 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
15476 new macros.

15481 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
15482 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
15483
15484 * src/vcg.h: Correct misspellings.
15485
15486 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
15487
15488
15489 * src/getargs.c (getargs): Don't assume EOF == -1.
15490
15491 2002-12-09 Paul Eggert <eggert@twinsun.com>
15492
15493 Change identifier spellings to avoid collisions with names
15494 that are reserved by POSIX.
15495
15496 Don't use names ending in _t, since POSIX reserves them.
15497 For consistency, remove _e and _s endings -- they're weren't
15498 needed to remove ambiguity. All uses changed.
15499 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
15500 turn was just renamed from struniq_t.
15501 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
15502 which in turn was just renamed from struniq_processor_t.

15574 value_t_as_yystype -> value_as_yystype.
15575
15576 Don't include <errno.h> in the mainstream code, since it

15589 (TAB_EXT): Renamed from EXT_TAB.
15590 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
15591

15594 likewise for "STRUNIQ" and "UNIQSTR".
15595 * src/uniqstr.c: Renamed from src/struniq.c.

15608 (N_EXPAND): Renamed from N_STRETCH.
15609

15612 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

15632 for consistency with other names.
15633 * lib/timevar.h (timevar_report): New decl.
15634 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
15635
15636
15637 Sort include-file uses.
15638
15639 Reorder all include files under src to be in the order "system.h".
15640 then the ../lib include files in angle brackets (alphabetized),
15641 then the . include files in double-quotes (alphabetized). Fix
15642 dependency breakages encountered in this process, as follows:
15643 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
15644 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
15645 * src/state.h: Include "symtab.h".
15646
15647 2002-12-08 Paul Eggert <eggert@twinsun.com>
15648
15649 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
15650 since this causes problems when __file__ contains character
15651 sequences like "@" that are treated specially by src/scan-skel.l.
15652 Instead, just use the file's basename. This fixes the bug
15653 reported by Martin Mokrejs in
15654 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
15655

15657
15658 Add support for rules that do not have trailing semicolons, as
15659 POSIX requires. Improve the quality of locations in Bison

15661
15662 * src/location.c: Include <quotearg.h>.
15663 (empty_location): Now const.
15664 (location_print): New function. Follow the recommendation of the
15665 GNU Coding Standards for locations that span file boundaries.
15666 * src/location.h: Do not include <quotearg.h>; no longer needed.
15667 (boundary): New type.
15668 (location_t): Use it. This allows locations to span file boundaries.
15669 All member uses changed: file -> start.file or end.file (as needed),
15670 first_line -> start.line, first_column -> start.column,
15671 last_line -> end.line, last_column -> end.column.
15672 (equal_boundaries): New function.
15673 (LOCATION_RESET, LOCATION_STEP): Remove.
15674 (LOCATION_PRINT): Remove. All callers changed to use location_print.
15675 (empty_location): Now const.
15676 (location_print): New decl.
15677 * src/parse-gram.y (lloc_default): New function, which handles
15678 empty locations more accurately.
15679 (YYLLOC_DEFAULT): Use it.
15680 (%token COLON): Remove.
15681 (%token ID_COLON): New token.
15682 (rules): Use it.

15687 (rules_or_grammar_declaration): Remove trailing semicolon.
15688 (semi_colon.opt): Remove.
15689 * src/reader.h: Include location.h.
15690 (scanner_cursor): New decl.
15691 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
15692 rolling our own.
15693 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
15694 of *loc.
15695 (STEP): Remove. No longer needed, now that adjust_location does
15696 the work. All uses removed.
15697 (scanner_cursor): New var.
15698 (adjust_location): Renamed from extend_location. It now sets
15699 *loc and adjusts the scanner cursor. All uses changed.
15700 Don't bother testing for CR.
15701 (handle_syncline): Remove location arg; now updates scanner cursor.
15702 All callers changed.
15703 (unexpected_end_of_file): Now accepts start boundary of token or
15704 comment, not location. All callers changed. Update scanner cursor,
15705 not the location.
15706 (SC_AFTER_IDENTIFIER): New state.
15707 (context_state): Renamed from c_context. All uses changed.
15708 (id_loc, code_start, token_start): New local vars.
15709 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
15710 processing of Yacc white space and equivalents here.
15711 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
15712 instead of returning ID immediately, since we need to search for
15713 a subsequent colon.
15714 (<INITIAL>"'", "\""): Save token_start.
15715 (<INITIAL>"%{", "{", "%%"): Save code_start.
15716 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
15717 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
15718 BEGIN context_state at end, not INITIAL.
15719 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
15720 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
15721 Return correct token start.
15722 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
15723 the start of a character, string or multiline comment is found.
15724 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
15725 Reduction): Adjust reported locations to match the more-precise
15726 results now expected.
15727 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
15728 * tests/reduce.at (Useless Rules, Reduced Automaton,
15729 Underivable Rules): Likewise.
15730 * tests/regression.at (Invalid inputs): No longer `expecting ";"
15731 or "|"' now that so many other tokens are allowed by the new grammar.
15732
15733 * src/complain.h (current_file): Remove duplicate decl;
15734 current_file is now owned by files.h.
15735 * src/complain.c, src/scan-gram.l: Include files.h.
15736
15737 2002-12-06 Paul Eggert <eggert@twinsun.com>
15738
15739 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
15740 promotes to int; it might be unsigned int.
15741 * data/yacc.c (yy_reduce_print): Likewise.
15742
15743 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
15744 be #defined in the prologue, not in the Bison declarations.
15745 This fixes Debian Bug 102878, reported by Shaul Karl.
15746
15747 2002-12-02 Paul Eggert <eggert@twinsun.com>
15748
15749 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
15750 * lib/strtoul.c: New file, from gnulib.
15751 This fixes a porting bug reported by Peter Klein in

15754 2002-11-30 Paul Eggert <eggert@twinsun.com>
15755
15756 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
15757 and put only a forward declaration in the prologue. This is for
15758 consistency with the other scanner helper functions.
15759
15760 Type clashes now generate warnings, not errors, since it
15761 appears that POSIX may allow some grammars with type clashes.
15762 * src/reader.c (grammar_current_rule_check): Warn about
15763 type clashes instead of complaining.
15764 * tests/input.at (Type Clashes): Expect warnings, not complaints.
15765
15766 Add Yacc library, since POSIX requires it.
15767 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
15768 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
15769 * lib/main.c, lib/yyerror.c: New files.
15770
15771 gram_error can be static; it need not be extern.
15772 * src/reader.h (gram_error): Remove decl.
15773 * src/parse-gram.y (gram_error): Now static. Add static decl.
15774 (print_token_value): Omit parameter names from forward decl,
15775 for consistency.
15776
15777 2002-11-29 Paul Eggert <eggert@twinsun.com>
15778
15779 * doc/bison.texinfo: Emphasize that yylex and yyerror must
15780 be declared before being used. E.g., one should typically
15781 declare them in the prologue. Use GNU coding style in examples.
15782 Put "const" consistently after the type it modifies. Mention
15783 that C99 supports "inline". Mention that yyerror traditionally
15784 returns "int".
15785
15786 %parse-param and %lex-param now take just one argument, the
15787 declaration; the argument name is deduced from the declaration.
15788
15789 * doc/bison.texinfo (Parser Function, Pure Calling, Error
15790 Reporting, Table of Symbols): Document this.
15791 * src/parse-gram.y (add_param): New function.
15792 (COMMA): Remove.
15793 (declaration): Implement new rule for %parse-param and %lex-param.
15794 * src/scan-gram.l: "," now elicits a warning, rather than being
15795 a token; this is more compatible with byacc.
15796 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
15797
15798 2002-11-27 Paul Eggert <eggert@twinsun.com>
15799
15800 Rename identifiers to avoid real and potential collisions.
15801
15802 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
15803 to avoid collision with lex macro described by Bruce Lilly in
15804 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
15805 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
15806 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
15807 * src/parse-gram.y (print_token_value): Renamed from yyprint.
15808 All uses changed.
15809 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
15810 The name "yycontrol" violates the name space rules, and this stuff
15811 wasn't being used anyway.
15812 (input): Remove action; this stuff wasn't being used.
15813 (gram_error): Rename local variable yylloc -> loc.
15814 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
15815 (YY_DECL): Don't use "yy" at start of local variables.
15816 All uses changed, e.g., yylloc -> loc.
15817 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
15818 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
15819 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
15820 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
15821
15822 * src/parse-gram.y (gram_error): loc is now const *.
15823 * src/reader.h (gram_error): Likewise.
15824
15825 2002-11-24 Paul Eggert <eggert@twinsun.com>
15826
15827 Version 1.75c.
15828
15829 * tests/actions.at (Actions after errors): Use an output format
15830 more similar to that of the Printers and Destructors test.
15831 Test the position of the ';' token too.
15832 (Printers and Destructors): Likewise.
15833 (Printers and Destructors: %glr-parser): Remove for now, to avoid
15834 unnecessarily alarming people when the test fails.
15835
15836 * data/yacc.c (yyerrlab1): Move this label down, so that the
15837 parser does not discard the lookahead token if the user code
15838 invokes YYERROR. This change is required for POSIX conformance.
15839
15840 * lib/error.c: Sync with gnulib.
15841
15842 2002-11-22 Paul Eggert <eggert@twinsun.com>
15843
15844 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
15845 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
15846 * lib/xmalloc.c: Likewise.
15847
15848 2002-11-20 Paul Eggert <eggert@twinsun.com>
15849
15850 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
15851
15852 2002-11-20 Paul Eggert <eggert@twinsun.com>
15853
15854 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
15855 should use `if (! x) abort ();' rather than `assert (x);', and
15856 anyway it's one less thing to worry about configuring.
15857
15858 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
15859 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
15860 and replace all instances of assert with abort.
15861 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
15862 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
15863
15864 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
15865 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
15866 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
15867 hash_find_entry, hash_rehash, hash_insert): Likewise.
15868 * src/conflicts.c (resolve_sr_conflict): Likewise.
15869 * src/lalr.c (set_goto_map, map_goto): Likewise.
15870 * src/nullable.c (nullable_compute): Likewise.
15871 * src/output.c (prepare_rules, token_definitions_output): Likewise.
15872 * src/reader.c (packgram, reader): Likewise.
15873 * src/state.c (state_new, state_free, state_transitions_set,
15874 state_reduction_find): Likewise.
15875 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
15876 symbol_pack): Likewise.
15877 * src/tables.c (conflict_row, pack_vector): Likewise.
15878 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
15879 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
15880 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
15881 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
15882
15883 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
15884 (ARGMATCH_CONSTRAINT): New macro.
15885 (ARGMATCH_ASSERT): Use it.
15886
15887 * src/system.h (verify): New macro.
15888 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
15889 rather than assert.
15890 * src/tables.c (tables_generate): Likewise.
15891
15892 * src/struniq.c (struniq_assert): Now returns void, and aborts
15893 if the assertion is false.
15894 (struniq_assert_p): Remove.
15895 * src/struniq.h: Likewise.
15896
15897 2002-11-18 Paul Eggert <eggert@twinsun.com>
15898
15899 * data/glr.c (yygetLRActions): Replace `yyindex' with
15900 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
15901 This fixes the regression with Sun ONE Studio 7 cc that I reported in
15902 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
15903
15904 2002-11-18 Akim Demaille <akim@epita.fr>
15905
15906 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
15907 space.
15908 From Tim Van Holder.
15909
15910 2002-11-17 Paul Eggert <eggert@twinsun.com>
15911
15912 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
15913 to "SyntaxError" for consistency with my 2002-11-15 change.
15914
15915 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
15916 not define to {}, since this breaks the common use of `YYDPRINTF
15917 ((...));' if a single statement is desired (e.g. before `else').
15918 Work around GCC warnings by surrounding corresponding calls with
15919 {} if needed.
15920 (yyhasResolvedValue): Remove unused function.
15921 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
15922 loop body.
15923 (yyreportSyntaxError): Renamed from yyreportParseError.
15924 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
15925 All uses changed.
15926 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
15927 extern when possible. Remove unused initializations.
15928
15929 2002-11-16 Akim Demaille <akim@epita.fr>
15930
15931 Augment the similarity between GLR and LALR traces.
15932
15933 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
15934 (YY_REDUCE_PRINT): New.
15935 (yyparse): Use them.
15936 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
15937 YYDPRINT here.
15938 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
15939 state reached after the reduction/recovery, since...
15940 (yyparse, yyprocessOneStack): Report the state we are entering in.
15941
15942 2002-11-16 Akim Demaille <akim@epita.fr>
15943
15944 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
15945 Add support for --trace=skeleton.
15946 * src/scan-skel.l: %option debug.
15947 Scan strings of non-@ or \n instead of character by character.
15948 (scan_skel): Handle trace_skeleton.
15949 (QPUTS): New.
15950 (@output_parser_name@, @output_header_name@): ``Restore'' their
15951 support (used to be M4 macros).
15952 * data/yacc.c: Quote larger chunks, a la glr.c.
15953 * data/lalr1.cc: Likewise.
15954 The header guards are no longer available, so use some other
15955 string than `YYLSP_NEEDED'.
15956
15957 2002-11-16 Akim Demaille <akim@epita.fr>
15958
15959 Make the ``Printers and Destructors'' test more verbose, taking
15960 `yacc.c''s behavior as (possibly wrong) reference.
15961
15962 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
15963 instead of fprint on stdout.
15964 Set and report the last_line of the symbols.
15965 Consistently display values and locations.
15966
15967 2002-11-16 Paul Eggert <eggert@twinsun.com>
15968
15969 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
15970
15971 2002-11-15 Paul Eggert <eggert@twinsun.com>
15972
15973 * tests/actions.at (Actions after errors): New test case.
15974
15975 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
15976 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
15977 tests/action.at, tests/calc.at, tests/conflicts.at,
15978 tests/cxx-type.at, tests/regression.at:
15979 "parse error" -> "syntax error" for POSIX compatibility.
15980 "parsing stack overflow..." -> "parser stack overflow" so
15981 that code matches Bison documentation.
15982
15983 2002-11-15 Akim Demaille <akim@epita.fr>
15984
15985 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
15986 take two BRACED_CODE, not two string_content.
15987 Free the scanner's obstack when we are done.
15988 (code_content): New.
15989 * tests/calc.at: Adjust.
15990 * doc/bison.texinfo: Adjust.
15991 Also, make sure to include the `,' for these declarations.
15992
15993 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
15994
15995 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
15996 definition; avoids potential autoreconf problems.
15997
15998 2002-11-15 Akim Demaille <akim@epita.fr>
15999
16000 Always check the value returned by yyparse.
16001
16002 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
16003 returned by yyparse.
16004 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
16005 Adjust calls.
16006 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
16007 returned by yyparse.
16008
16009 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16010
16011 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
16012 on input.at test.
16013
16014 2002-11-14 Paul Eggert <eggert@twinsun.com>
16015
16016 * src/output.c (output_skeleton): Call xfopen instead of
16017 duplicating xfopen's body.
16018
16019 Fix bugs reported by Nelson H. F. Beebe in
16020 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
16021
16022 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
16023 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
16024 Group compiler. Instead, use "$CC -E bar.c". Include the .h
16025 file twice in the grammar, as an extra check.
16026
16027 * tests/input.at (Torturing the Scanner): Surround the
16028 backslash-newline tests with "#if 0", to make it less likely that
16029 we'll run into compiler bugs. Bring back solitary \ inside
16030 comment, but add a closing comment to work around HP C bug. Don't
16031 test backslash-newline in C character constant.
16032
16033 2002-11-14 Akim Demaille <akim@epita.fr>
16034
16035 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
16036 status of the compiler.
16037 Calling `exit 1' is no longer needed.
16038 Reported by Nelson H. F. Beebe.
16039
16040 2002-11-14 Akim Demaille <akim@epita.fr>
16041
16042 * tests/atlocal.in (CPPFLAGS): We have config.h.
16043 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
16044 New.
16045 * tests/actions.at, tests/calc.at, tests/conflicts.at,
16046 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
16047 * tests/regression.at, tests/torture.at: Use them for all the
16048 grammars that are to be compiled.
16049 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
16050 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
16051 * doc/bison.texinfo (GLR Parsers): Document `inline'.
16052
16053 2002-11-14 Akim Demaille <akim@epita.fr>
16054
16055 * doc/bison.texinfo: Various formatting changes (alignments in
16056 samples, additional @group/@end group, GCS in samples.
16057 Use @deffn instead of simple @table to define the directives,
16058 macros, variables etc.
16059
16060 2002-11-13 Paul Eggert <eggert@twinsun.com>
16061
16062 Fix some bugs reported by Albert Chin-A-Young in
16063 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
16064
16065 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
16066 -o c"; the HP C compiler chatters during compilation.
16067 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
16068 * tests/headers.at (export YYLTYPE): Likewise.
16069
16070 * tests/input.at (Torturing the Scanner): Remove lines containing
16071 solitary backslashes, as they tickle a bug in the HP C compiler.
16072
16073 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
16074 comments, since they're not portable. Use GNU coding style.
16075
16076 2002-11-13 Akim Demaille <akim@epita.fr>
16077
16078 * data/yacc.c: Leave bigger chunks of quoted text.
16079 (YYDSYMPRINTF): New.
16080 Use it to report symbol activities.
16081 * data/glr.c (YYDSYMPRINTF): New.
16082 Use it.
16083
16084 2002-11-12 Paul Eggert <eggert@twinsun.com>
16085
16086 Version 1.75b.
16087
16088 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
16089 (yyglrReduce): Return yyok, not 0.
16090 This should avoid the enumerated-type warnings reported
16091 by Nelson H. F. Beebe in
16092 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
16093
16094 * lib/bbitset.h (BITSET_INLINE): Remove.
16095 * lib/bitset.h [! BITSET_INLINE]: Remove.
16096 (bitset_set, bitset_reset, bitset_test): Rename local vars
16097 to avoid shadowing warnings by GCC.
16098
16099 * data/glr.c (inline): Remove #define. It's the user's
16100 responsibility to #define it away, just like 'const'.
16101 This fixes one of the bugs reported by Nelson H. F. Beebe in
16102 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
16103
16104 * Makefile.maint (po-check): Scan .l and .y files instead of the
16105 .c and the .h files that they generate. This fixes the bug
16106 reported by Tim Van Holder in:
16107 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
16108 Look for N_ as well as for _. Try to avoid matching #define for
16109 N_ and _.
16110 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
16111 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
16112 * src/scan-gram.l: Revamp regular expressions so that " and '
16113 do not confuse xgettext.
16114
16115 * src/struniq.h (struniq_new): Do not declare the return type
16116 to be 'const'; this violates the C standard.
16117 * src/struniq.c (struniq_new): Likewise.
16118
16119 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
16120
16121 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
16122 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
16123 linker.
16124
16125 2002-11-12 Akim Demaille <akim@epita.fr>
16126
16127 * Makefile.maint: Sync with Autoconf:
16128 (local_updates): New.
16129
16130 2002-11-12 Akim Demaille <akim@epita.fr>
16131
16132 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
16133
16134 2002-11-12 Akim Demaille <akim@epita.fr>
16135
16136 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
16137 locations.
16138
16139 2002-11-12 Akim Demaille <akim@epita.fr>
16140
16141 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
16142 not yyvalue.
16143
16144 2002-11-12 Akim Demaille <akim@epita.fr>
16145
16146 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
16147 Use it to test the GLR parser.
16148
16149 2002-11-12 Akim Demaille <akim@epita.fr>
16150
16151 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton

16164 * tests/cations.at (Printers and Destructors): Use Bison directives
16165 instead of CPP macros.

16167
16168 2002-11-12 Akim Demaille <akim@epita.fr>
16169
16170 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
16171 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
16172 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
16173 it against YYEMPTY and so forth), work on yytoken (i.e., set
16174 it to YYEMPTY etc.).
16175 (yydestruct): Replace with a b4_yydestruct_generate invocation.
16176 (b4_symbol_actions): Remove.
16177 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands

16181
16182 * doc/bison.texinfo (Destructor Decl): New.

16185
16186 * src/tables.c (tables_generate): Use free for pointers that

16190 * src/reader.c (reader): Likewise.
16191 * src/lalr.c (set_goto_map): Likewise.
16192 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue

16194
16195 2002-11-12 Akim Demaille <akim@epita.fr>
16196
16197 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
16198 Restore.
16199 * src/scan-gram.l (last_string): Is global to the file, not to
16200 yylex.
16201 * src/parse-gram.y (input): Don't append the epilogue here,
16202 (epilogue.opt): do it here, and free the scanner's obstack.
16203 * src/reader.c (epilogue_set): Rename as...
16204 (epilogue_augment): this.
16205 * data/c.m4 (b4_epilogue): Defaults to empty.
16206
16207 2002-11-12 Akim Demaille <akim@epita.fr>
16208

16214
16215 2002-11-12 Akim Demaille <akim@epita.fr>
16216
16217 * src/struniq.h, src/struniq.c (struniq_t): Is const.
16218 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
16219
16220 Use struniq for symbols.
16221
16222 * src/symtab.h (symbol_t): The tag member is a struniq.
16223 (symbol_type_set): Adjust.

16227 (hash_compare_symbol, hash_symbol): these.
16228 Use the fact that tags as struniqs.
16229 (symbol_get): Use struniq_new.
16230 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
16231 Returns a strniq.

16239
16240 * src/files.h, src/files.c (infile): Split into...
16241 (grammar_file, current_file): these.
16242 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
16243 * src/reduce.c (reduce_print): Likewise.

16245 * src/complain.h, src/complain.c: Likewise.
16246 * src/main.c (main): Call struniqs_new early enough to use it for
16247 file names.
16248 Don't free the input file name.
16249
16250 2002-11-12 Akim Demaille <akim@epita.fr>
16251
16252 * src/symtab.c (symbol_free): Remove dead deactivated code:

16254 Don't use XFREE to free items that cannot be NULL.
16255 * src/struniq.h, src/struniq.c: New.

16262
16263 2002-11-11 Paul Eggert <eggert@twinsun.com>
16264
16265 Revamp to fix many (but not all) of the C- and M4-related quoting
16266 problems. Among other things, this fixes the Bison bug reported
16267 by Jan Hubicka when processing the Bash grammar; see:
16268 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
16269
16270 Use new @ escapes consistently. Represent brackets with @{ and @}
16271 rather than @<:@ and @:>@, since this works a bit better with dumb
16272 editors like vi. Represent @ with @@, since @ is now consistently
16273 an escape. Use @oline@ and @ofile@ rather than __oline__ and
16274 __ofile__, to avoid unexpected expansions. Similarly, use @output
16275 rather than #output.
16276
16277 * data/c.m4 (b4_copyright): Omit file name from comment, since
16278 the file name could contain "*/".
16279 (b4_synclines_flag): Don't quote the 2nd argument; it should already
16280 be quoted. All uses changed.
16281
16282 * data/glr.c: Use new @ escapes consistently.
16283 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
16284 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
16285 Remove, since they couldn't handle arbitrary characters in file
16286 names.
16287 * data/lalr1.cc: Likewise.
16288 * data/yacc.c: Likewise.
16289
16290 * src/files.c (output_infix): Remove; all uses removed.
16291 * src/files.h: Likewise.
16292
16293 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
16294 mishandled funny characters in file names, and anyway it isn't
16295 needed any more.
16296 * data/yacc.c: Likewise.
16297 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
16298
16299 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
16300 * data/yacc.c: Likewise.
16301
16302 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
16303 strings now.
16304 (muscle_init): Quote filename as a C string.
16305 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
16306 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
16307 * src/output.c (escaped_file_name_output): New function.
16308 (prepare_symbols): Quote tokens for M4.
16309 (prepare): Don't insert output_infix, output_prefix,
16310 output_parser_name, output_header_name; this is now down by scan-skel.
16311 Insert skeleton as a C string.
16312
16313 * src/output.c (user_actions_output, symbol_destructors_output,
16314 symbol_printers_output): Quote filenames for C and M4.
16315 * src/reader.c (prologue_augment, epilogue_set): Likewise.
16316
16317 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
16318 escapes other than \\ and \'; this simplifies the code.
16319 (<SC_STRING>): Likewise, for \\ and \".
16320 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
16321 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
16322 Use new escapes @{ and @} for [ and ].
16323
16324 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
16325 them with auto vars.
16326 Switch to new escape scheme, where @ is the escape character uniformly.
16327 Abort if a stray escape character is found. Avoid unbounded input
16328 buffer when parsing non-escaped text.
16329
16330 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
16331 __oline__, #output, $@, and @{ do not have unintended meanings.
16332
16333 2002-11-09 Paul Eggert <eggert@twinsun.com>
16334
16335 Fix the test failure due to GCC warnings described in
16336 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
16337 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
16338 evaluate to 0 if it's impossible for NINF to be in the respective
16339 table.
16340 (yygetLRActions, yyrecoverParseError): Use them.
16341
16342 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
16343 counted in the token inserted at end of file. Now takes
16344 location_t *, not location_t, so that the location can be
16345 adjusted. All uses changed.
16346
16347 * tests/regression.at (Invalid inputs): Adjust wording in
16348 diagnostic to match the new behavior.
16349
16350 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
16351 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
16352 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
16353 abort ();'. This reduces the runtime of the "Many lookaheads"
16354 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
16355 GCC 3.2.
16356
16357 2002-11-07 Paul Eggert <eggert@twinsun.com>
16358
16359 * src/parse-gram.y (CHARACTER): Remove unused token.
16360 All uses removed.
16361
16362 * src/scan-gram.l: Remove stack option. We no longer use the
16363 stack, since the stack was never deeper than 1; instead, use the
16364 new auto var c_context to record the stacked value.
16365
16366 Remove nounput option. At an unexpected end of file, we now unput
16367 the minimal input necessary to end cleanly; this simplifies the
16368 code.
16369
16370 Avoid unbounded token sizes where this is easy.
16371
16372 (unexpected_end_of_file): New function.
16373 Use it to systematize the error message on unexpected EOF.
16374 (last-string): Now auto, not static.
16375 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
16376 (scanner_last_string_free): Remove; not used.
16377 (percent_percent_count): Move decl to just before use.
16378 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
16379 not the (never otherwised-used) CHARACTER.
16380
16381 2002-11-07 Akim Demaille <akim@epita.fr>
16382
16383 Let yyerror always receive the msg as last argument, so that
16384 yyerror can be variadic.
16385
16386 * data/yacc.c (b4_yyerror_args): New.
16387 Use it when calling yyerror.
16388 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
16389 Use it when calling yyerror.
16390 * doc/bison.texinfo (Error Reporting): Adjust.
16391 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
16392 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
16393
16394 2002-11-06 Akim Demaille <akim@epita.fr>
16395
16396 #line should have quoted strings.
16397 Ideally, this should be done by m4_quotearg.
16398
16399 * src/scan-skel.l: Include quotearg.h.
16400 Quote __ofile__.
16401 * src/output.c (symbol_printers_output)
16402 (symbol_destructors_output): Quote the file name.
16403
16404 2002-11-06 Akim Demaille <akim@epita.fr>
16405
16406 * tests/regression.at (Invalid inputs): Adjust to the recent
16407 messages.
16408
16409 2002-11-06 Akim Demaille <akim@epita.fr>
16410
16411 Restore --no-lines.
16412 Reported by Jim Kent.
16413
16414 * data/c.m4 (b4_syncline): New.
16415 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
16416 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
16417 * src/output.c (user_actions_output): Likewise.
16418 (prepare): Define 'b4_synclines_flag'.
16419 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
16420
16421 2002-11-06 Akim Demaille <akim@epita.fr>
16422
16423 * src/main.c (main): Free `infile'.
16424 * src/scan-gram.l (handle_syncline): New.
16425 Recognize `#line'.
16426 * src/output.c (user_actions_output, symbol_destructors_output)
16427 (symbol_printers_output): Use the location's file name, not
16428 infile.
16429 * src/reader.c (prologue_augment, epilogue_set): Likewise.
16430
16431 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16432
16433 * src/tables.c (matching_state): Don't allow states to match if
16434 either has GLR conflict entries.
16435
16436 2002-11-05 Paul Eggert <eggert@twinsun.com>
16437
16438 * src/scan-gram.l: Use more accurate diagnostics, e.g.
16439 "integer out of range" rather than "invalid value".
16440 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
16441 accordingly.
16442
16443 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
16444 Also, remove one static variable in the scanner.
16445
16446 * src/scan-gram.l (braces_level): Now auto, not static.
16447 Initialize to zero if the compiler is being picky.
16448 (INITIAL): Clear braces_level instead of incrementing it.
16449 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
16450 as POSIX 1003.1-2001 requires.
16451 * src/system.h (IF_LINT): New macro, taken from coreutils.
16452 * configure.ac: Define "lint" if --enable-gcc-warnings.
16453
16454 2002-11-05 Akim Demaille <akim@epita.fr>
16455
16456 * src/scan-gram.l: When it starts with `%', complain about the
16457 whole directive, not just that `invalid character: %'.
16458
16459 2002-11-04 Akim Demaille <akim@epita.fr>
16460
16461 * Makefile.maint: Update from Autoconf.

16465
16466 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
16467 and yyerror.
16468 Have yyerror `use' its arguments.
16469 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
16470 returns true when location & yacc & pure & parse-param.
16471 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
16472

16481 slot 0.
16482
16483 2002-11-03 Paul Eggert <eggert@twinsun.com>
16484
16485 * src/reader.c (get_merge_function, grammar_current_rule_check):

16509 When using a pure parser, also need the parse-params.
16510 Adjust callers.

16555 Use {splice} wherever C allows backslash-newline.
16556 YY_STEP after space, newline, vertical-tab.
16557 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
16558
16559 (letter, id): Don't assume ASCII; e.g., spell out a-z.
16560
16561 ({int}, handle_action_dollar, handle_action_at): Check for integer
16562 overflow.
16563
16564 (YY_STEP): Omit trailing semicolon, so that it's more like C.
16565
16566 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
16567 as well as \000. Check for UCHAR_MAX, not 255.
16568 Allow \x with an arbitrary positive number of digits, as in C.
16569 Check for overflow here.
16570 Allow \? and UCNs, for compatibility with C.
16571
16572 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
16573 with quote slot used by complain_at.
16574
16575 * tests/input.at: Add tests for backslash-newline, m4 quotes
16576 in symbols, long literals, and funny escapes in strings.
16577
16578 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
16579 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
16580 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
16581 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
16582 * m4/mbswidth.m4: New file, from GNU coreutils.
16583
16584 * doc/bison.texinfo (Grammar Outline): Document // comments.
16585 (Symbols): Document that trigraphs have no special meaning in Bison,
16586 nor is backslash-newline allowed.
16587 (Actions): Document that trigraphs have no special meaning.
16588
16589 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
16590 no longer used.
16591
16592 2002-11-02 Paul Eggert <eggert@twinsun.com>
16593
16594 * src/reader.c: Don't include quote.h; not needed.
16595 (get_merge_function): Reword warning to be consistent with
16596 type clash diagnostic in grammar_current_rule_check.
16597
16598 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
16599 bug in trigraph handling.
16600
16601 * src/output.c (prepare_symbols): When printing token names,
16602 escape "[" as "@<:@" and likewise for "]".
16603
16604 * src/system.h (errno): Remove declaration, as we are now
16605 assuming C89 or better, and C89 guarantees errno.
16606
16607 2002-10-30 Paul Eggert <eggert@twinsun.com>
16608
16609 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
16610 Check for close failures.
16611 * src/files.h (xfclose): Return void, not int, since it always
16612 returned zero.
16613 * src/files.c (xfclose): Likewise. Report I/O error if ferror
16614 indicates one.
16615 * src/output.c (output_skeleton): Use xfclose rather than fclose
16616 and ferror. xfclose now checks ferror.
16617
16618 * data/glr.c (YYLEFTMOST_STATE): Remove.
16619 (yyreportTree): Use a stack-based leftmost state. This avoids
16620 our continuing battles with bogus warnings about initializers.
16621
16622 2002-10-30 Akim Demaille <akim@epita.fr>
16623
16624 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
16625 #if.
16626
16627 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16628
16629 * tests/glr-regr1.at: New test for reported regressions.
16630 * tests/testsuite.at: Add glr-regr1.at test.
16631 * tests/Makefile.am: Add glr-regr1.at test.
16632
16633 2002-10-24 Paul Eggert <eggert@twinsun.com>
16634
16635 Version 1.75a.
16636
16637 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
16638 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
16639 we use malloc. Don't assume 'A' through 'Z' are contiguous.
16640 Don't assume strdup exists; POSIX says its an XSI extension.
16641 Check for buffer overflow on input.
16642
16643 2002-10-24 Akim Demaille <akim@epita.fr>
16644
16645 * src/output.c (output_skeleton): Don't disable M4sugar comments
16646 too soon: it results in comments being expanded.
16647 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
16648 first output.
16649
16650 2002-10-24 Akim Demaille <akim@epita.fr>
16651
16652 * data/yacc.c (m4_int_type): New.
16653 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
16654 char' as only yacc.c wants K&R portability.
16655 * data/glr.c (yysigned_char): Remove.
16656 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
16657 Reported by Quoc Peyrot.
16658
16659 2002-10-23 Paul Eggert <eggert@twinsun.com>
16660
16661 * src/main.c (main): With --trace=time, report times even if a
16662 non-fatal error occurs. Formerly, the times were reported in some
16663 such cases but not in others.
16664 * src/reader.c (reader): Just return if a complaint has been issued,
16665 instead of exiting, so that 'main' can report times.
16666
16667 2002-10-22 Akim Demaille <akim@epita.fr>
16668
16669 * src/system.h: Include sys/types.
16670 Reported by Bert Deknuydt.
16671
16672 2002-10-23 Paul Eggert <eggert@twinsun.com>
16673
16674 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
16675 Suggested by Art Haas.
16676
16677 2002-10-22 Paul Eggert <eggert@twinsun.com>
16678
16679 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
16680 decl; not needed any more.
16681 * src/main.c (main): Use return to exit, undoing yesterday's change.
16682 The last OS that we could find where this wouldn't work is
16683 SunOS 3.5, and that's too old to worry about now.
16684
16685 * data/glr.c (struct yyltype): Define members even when not
16686 doing locations. This is more consistent with yacc.c, and it
16687 works around the following bug reports:
16688 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
16689 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
16690
16691 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
16692 @acronym consistently. Standardize on "Yacc" instead of "YACC",
16693 "Algol" instead of "ALGOL". Give a bit more history about BNF.
16694
16695 2002-10-22 Akim Demaille <akim@epita.fr>
16696
16697 * data/README: New.
16698
16699 2002-10-21 Paul Eggert <eggert@twinsun.com>
16700
16701 Be consistent about 'bool'; the old code used an enum in one
16702 module and an int in another, and this violates the C standard.
16703 * m4/stdbool.m4: New file, from coreutils 4.5.3.
16704 * configure.ac (AC_HEADER_STDBOOL): Add.
16705 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
16706 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
16707 * src/symtab.c (hash_compare_symbol_t): Likewise.
16708 * src/system.h (bool, false, true): Use a definition consistent
16709 with ../lib/hash.c. All uses changed.
16710
16711 * src/complain.c (warning_issued): Renamed from warn_message_count,
16712 so that we needn't worry about integer overflow (!).
16713 Now of type bool. All uses changed.
16714 (complaint_issued): Renamed from complain_message_count; likewise.
16715
16716 * src/main.c (main): Use exit to exit with failure.
16717
16718 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
16719 rather than 1 and 0.
16720 * src/main.c (main): Likewise.
16721 * src/getargs.c (getargs): Likewise.
16722 * src/reader.c (reader): Likewise.
16723
16724 * src/getarg.c (getargs): Remove duplicate code for
16725 "Try `bison --help'".
16726
16727 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
16728 What was that "2" for?
16729
16730 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
16731 * src/getargs.c (usage): Likewise.
16732
16733 * src/getargs.c (getargs): When there are too few operands, report
16734 the last one. When there are too many, report the first extra
16735 one. This is how diffutils does it.
16736
16737 2002-10-20 Paul Eggert <eggert@twinsun.com>
16738
16739 Remove K&R vestiges.
16740 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
16741 * src/complain.c (VA_START): Remove. Assume prototypes.
16742 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
16743 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
16744 fatal): Assume prototypes.
16745 * src/complain.h: Assume prototypes.
16746 * src/system.h (PARAMS): Remove.
16747 Include <limits.h> unconditionally, since it's guaranteeed even
16748 for a freestanding C89 compiler.
16749 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
16750 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
16751
16752 2002-10-20 Akim Demaille <akim@epita.fr>
16753
16754 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
16755 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
16756 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
16757 (yyresolveStates, yyresolveAction, yyresolveStack)
16758 (yyprocessOneStack): Use them.
16759 (yy_reduce_print): New.
16760 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
16761
16762 2002-10-20 Akim Demaille <akim@epita.fr>
16763
16764 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
16765 arguments and output `void'.
16766 (b4_c_function): Rename as...
16767 (b4_c_function_def): this.
16768 (b4_c_function_decl, b4_c_ansi_function_def)
16769 (b4_c_ansi_function_decl): New.
16770 Change the interpretation of the arguments: before `int, foo', now
16771 `int foo, foo'.
16772 * data/yacc.c (yyparse): Prototype and define thanks to these.
16773 Adjust b4_c_function_def uses.
16774 * data/glr.c (yyparse): Likewise, but ANSI only.
16775
16776 2002-10-20 Akim Demaille <akim@epita.fr>
16777
16778 * src/output.c (prepare): Move the definition of `tokens_number',
16779 `nterms_number', `undef_token_number', `user_token_number_max'
16780 to...
16781 (prepare_tokens): Here.
16782 (prepare_tokens): Rename as...
16783 (prepare_symbols): this.
16784 (prepare): Move the definition of `rules_number' to...
16785 (prepare_rules): here.
16786 (prepare): Move the definition of `last', `final_state_number',
16787 `states_number' to...
16788 (prepare_states): here.
16789 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
16790
16791 2002-10-20 Akim Demaille <akim@epita.fr>
16792
16793 * src/tables.h, src/tables.c, src/output.c: Comment changes.
16794
16795 2002-10-20 Akim Demaille <akim@epita.fr>
16796
16797 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
16798 * data/c.m4: here.
16799
16800 2002-10-20 Akim Demaille <akim@epita.fr>
16801
16802 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
16803 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
16804 `pair'.
16805 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
16806 `name' to...
16807 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
16808 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
16809 These.
16810
16811 2002-10-19 Paul Eggert <eggert@twinsun.com>
16812
16813 Do not create a temporary file, as that involves security and
16814 cleanup headaches. Instead, use a pair of pipes.
16815 Derived from a suggestion by Florian Krohm.
16816 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
16817 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
16818 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
16819 (BISON_PREREQ_SUBPIPE): Add.
16820 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
16821 Add subpipe.h, subpipe.c.
16822 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
16823 * po/POTFILES.in: Add lib/subpipe.c.
16824 * src/output.c: Include "subpipe.h".
16825 (m4_invoke): Remove decl.
16826 (scan_skel): New decl.
16827 (output_skeleton): Use pipe rather than temporary file for m4 input.
16828 Check that m4sugar.m4 is readable, to avoid deadlock.
16829 Check for pipe I/O error.
16830 * src/scan-skel.l (readpipe): Remove decl.
16831 (scan_skel): New function, to be used in place of m4_invoke.
16832 Read from stream rather than file.
16833
16834 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
16835 float, as this generates a warning on Solaris 8 + GCC 3.2 with
16836 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
16837 this generates a more-accurate value anyway.
16838
16839 * lib/timevar.c (timervar_accumulate): Rename locals to
16840 avoid confusion with similarly-named more-global.
16841 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
16842
16843 * src/output.c (prepare): Use xstrdup to convert char const *
16844 to char *, to avoid GCC warning.
16845
16846 2002-10-19 Akim Demaille <akim@epita.fr>
16847
16848 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
16849 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
16850 Use them to have `calc.y' ready for %pure-parser.
16851 * data/yacc.c (YYLEX): Pass a yylex return type to
16852 b4_c_function_call.
16853
16854 2002-10-19 Akim Demaille <akim@epita.fr>
16855
16856 Prototype support of %lex-param and %parse-param.
16857
16858 * src/parse-gram.y: Add the definition of the %lex-param and
16859 %parse-param tokens, plus their rules.
16860 Drop the `_' version of %glr-parser.
16861 Add the "," token.
16862 * src/scan-gram.l (INITIAL): Scan them.
16863 * src/muscle_tab.c: Comment changes.
16864 (muscle_insert, muscle_find): Rename `pair' as `probe'.
16865 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
16866 (muscle_entry_s): The `value' member is no longer const.
16867 Adjust all dependencies.
16868 * src/muscle_tab.c (muscle_init): Adjust: use
16869 MUSCLE_INSERT_STRING.
16870 Initialize the obstack earlier.
16871 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
16872 (muscle_pair_list_grow): New.
16873 * data/c.m4 (b4_c_function_call, b4_c_args): New.
16874 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
16875 * tests/calc.at: Use %locations, not --locations.
16876 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
16877
16878 2002-10-19 Akim Demaille <akim@epita.fr>
16879
16880 * src/getargs.c (usage): Take status as argument and exit
16881 accordingly.
16882 Report the traditional `Try ... --help' message when status != 0.
16883 (usage, version): Don't take a FILE * as arg, it is pointless.
16884 (getargs): When there is an incorrect number of arguments, make it
16885 an error, and report it GNUlically thanks to `usage ()'.
16886
16887 2002-10-18 Paul Eggert <eggert@twinsun.com>
16888
16889 * data/glr.c (yyreportParseError): Don't assume that sprintf
16890 yields the length of the printed string, as this is not true
16891 on SunOS 4.1.4. Reported by Peter Klein.
16892
16893 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
16894 * tests/conflicts.at (%nonassoc and eof): Likewise.
16895 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
16896
16897 2002-10-17 Akim Demaille <akim@epita.fr>
16898
16899 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
16900 * src/getargs.c (trace_types, trace_args): Adjust.
16901 * src/reader.c (grammar_current_rule_prec_set)
16902 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
16903 Standardize error messages.
16904 And s/@prec/%prec/!
16905 (reader): Use trace_flag to enable scanner/parser debugging,
16906 instead of an adhoc scheme.
16907 * src/scan-gram.l: Remove trailing debugging code.
16908
16909 2002-10-16 Paul Eggert <eggert@twinsun.com>
16910
16911 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
16912 MUSCLE_TAB_H.
16913
16914 * NEWS: Officially drop support for building Bison with K&R C,
16915 since it didn't work anyway and it's not worth worrying about.
16916 * Makefile.maint (wget_files): Remove ansi2knr.c.
16917 (ansi2knr.c-url_prefix): Remove.
16918 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
16919 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
16920 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
16921
16922 2002-10-15 Paul Eggert <eggert@twinsun.com>
16923
16924 Stop using the "enum_" trick for K&R-style function definitions;
16925 it confused me, and I was the author! Instead, assume that people
16926 who want to use K&R C compilers (when using these modules in GCC,
16927 perhaps?) will run ansi2knr.
16928
16929 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
16930 All uses of "enum_" changed to "enum ".
16931 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
16932 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
16933
16934 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,
16935 abitset_and_or_cmp, abitset_andn, abitset_andn_cmp,
16936 abitset_andn_or, abitset_andn_or_cmp, abitset_bytes, abitset_copy,
16937 abitset_copy1, abitset_disjoint_p, abitset_empty_p,
16938 abitset_equal_p, abitset_init, abitset_list, abitset_list_reverse,
16939 abitset_not, abitset_ones, abitset_or, abitset_or_and,
16940 abitset_or_and_cmp, abitset_or_cmp, abitset_reset, abitset_set,
16941 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
16942 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
16943 Use function prototypes; this removes the need for declaring
16944 static functions simply to provide their prototypes.
16945 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

17000 Version 1.75.
17001
17002 2002-10-14 Akim Demaille <akim@epita.fr>
17003
17004 * tests/Makefile.am (maintainer-check-posix): New.
17005
17006 2002-10-14 Akim Demaille <akim@epita.fr>
17007
17008 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
17009 member.
17010
17011 2002-10-14 Akim Demaille <akim@epita.fr>
17012
17013 * src/tables.c (table_ninf_remap): base -> tab.
17014 Reported by Matt Rosing.
17015
17016 2002-10-14 Paul Eggert <eggert@twinsun.com>
17017
17018 * tests/action.at, tests/calc.at, tests/conflicts.at,
17019 tests/cxx-type.at, tests/headers.at, tests/input.at,
17020 tests/regression.at, tests/synclines.at, tests/torture.at:
17021 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
17022 so that the tests still work even if POSIXLY_CORRECT is set.
17023 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
17024
17025 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
17026 for portability to K&R hosts. Fix typo: signed char is guaranteed
17027 only to 127, not to 128.
17028 * data/glr.c (yysigned_char): New type.
17029 * data/yacc.c (yysigned_char): Likewise.
17030 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
17031
17032 2002-10-13 Paul Eggert <eggert@twinsun.com>
17033
17034 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
17035 true due to limited range of data type" warning from GCC.
17036
17037 * data/c.m4 (b4_token_defines): Protect against double-inclusion
17038 by wrapping enum yytokentype's definition inside #ifndef
17039 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
17040
17041 2002-10-13 Akim Demaille <akim@epita.fr>
17042
17043 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
17044 Un yy- yyrhs to avoid the name clash with the global YYRHS.
17045
17046 2002-10-13 Akim Demaille <akim@epita.fr>
17047
17048 * Makefile.maint: Update from Autoconf 2.54.
17049 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
17050
17051 2002-10-13 Akim Demaille <akim@epita.fr>
17052
17053 * src/print.c (print_state): Separate the list of solved conflicts
17054 from the other items.
17055 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
17056
17057 2002-10-13 Akim Demaille <akim@epita.fr>
17058
17059 Let nondeterministic skeletons be usable with deterministic
17060 tables.
17061
17062 With the patch, GAWK compiled by GCC without -O2 passes its test
17063 suite using a GLR parser driven by LALR tables. It fails with -O2
17064 because `struct stat' gives two different answers on my machine:
17065 88 (definition of an auto var) and later 96 (memset on this var).
17066 Hence the stack is badly corrumpted. The headers inclusion is to
17067 blame: if I move the awk.h inclusion before GLR's system header
17068 inclusion, the two struct stat have the same size.
17069
17070 * src/tables.c (pack_table): Always create conflict_table.
17071 (token_actions): Always create conflict_list.
17072 * data/glr.c (YYFLAG): Remove, unused.
17073
17074 2002-10-13 Akim Demaille <akim@epita.fr>
17075
17076 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
17077 (O0FLAGS): New.
17078 (VALGRIND, GXX): New.
17079 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
17080 * tests/bison.in: Run $PREBISON a pre-command.
17081 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
17082 (maintainer-check-g++): New.
17083 * Makefile.am (maintainer-check): New.
17084
17085 2002-10-13 Akim Demaille <akim@epita.fr>
17086
17087 * data/glr.c: Formatting changes.
17088 Tweak some trace messages to match yacc.c's.
17089
17090 2002-10-13 Akim Demaille <akim@epita.fr>
17091
17092 GLR parsers sometimes raise parse errors instead of performing the
17093 default reduction.
17094 Reported by Charles-Henry de Boysson.
17095
17096 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
17097 check the length of the traces when %glr.
17098 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
17099 GLR's traces.
17100 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
17101 Test GLR parsers.
17102 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
17103 (yyltype): Remove the yy prefix from the member names.
17104 (yytable): Complete its comment.
17105 (yygetLRActions): Map error action number from YYTABLE from
17106 YYTABLE_NINF to 0.
17107 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
17108 (which was a bug: it should have been YYTABEL_NINF, and yet it was
17109 not satisfying as we could compare an YYACTION computed from
17110 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
17111 only value for error actions.
17112 (yyreportParseError): In verbose parse error messages, don't issue
17113 `error' in the list of expected tokens.
17114 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
17115 next action to perform to match glr.c's decoding.
17116 (yytable): Complete its comment.
17117
17118 2002-10-13 Paul Eggert <eggert@twinsun.com>
17119
17120 Fix problem reported by Henrik Grubbstroem in
17121 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
17122 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
17123 because the Bison parser reads the second action before reducing
17124 the first one.
17125 * src/scan-gram.l (rule_length): New static var.
17126 Use it to keep track of the rule length in the scanner, since
17127 we can't expect the parser to be in lock-step sync with the scanner.
17128 (handle_action_dollar, handle_action_at): Use this var.
17129 * tests/actions.at (Exotic Dollars): Test for the problem.
17130
17131 2002-10-12 Paul Eggert <eggert@twinsun.com>
17132
17133 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
17134 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
17135 Include <sys/time.h> when checking for clock_t and struct tms.
17136 Use same include order as source.
17137 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
17138 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
17139
17140 * lib/timevar.c: Update copyright date and clarify comments.
17141 (get_time) [IN_GCC]: Keep the GCC version for reference.
17142
17143 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
17144 GCC version as of today, then merge Bison's changes.
17145 Change "GCC" to "Bison" in copyright notice. timevar.def's
17146 author is Akim, so change that too.
17147
17148 * src/reader.c (grammar_current_rule_check):
17149 Don't worry about the default action if $$ is untyped.
17150 Prevents bogus warnings reported by Jim Gifford in
17151 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
17152
17153 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
17154 * data/glr.c, data/lalr1.cc, data/yacc.c:
17155 Output token definitions before the first part of user declarations.
17156 Fixes compatibility problem reported by Jim Gifford for kbd in
17157 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
17158
17159 2002-10-11 Paul Eggert <eggert@twinsun.com>
17160
17161 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
17162 (yyparse): here. This undoes some of the 2002-07-25 change.
17163 Compatibility problem reported by Ralf S. Engelschall with
17164 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
17165
17166 2002-10-11 Akim Demaille <akim@epita.fr>
17167
17168 * tests/regression.at Characters Escapes): New.
17169 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
17170 characters.
17171 Reported by Jan Nieuwenhuizen.
17172
17173 2002-10-11 Akim Demaille <akim@epita.fr>
17174
17175 * po/id.po: New.
17176
17177 2002-10-10 Paul Eggert <eggert@twinsun.com>
17178
17179 Portability fixes for bitsets; this also avoids several GCC
17180 warnings.
17181
17182 * lib/abitset.c: Include <stddef.h>, for offsetof.
17183 * lib/lbitset.c: Likewise.
17184
17185 * lib/abitset.c (abitset_bytes): Return a size that is aligned
17186 properly for vectors of objects. Do not assume that adding a
17187 header size to a multiple of a word size yields a value that is
17188 properly aligned for the whole union.
17189 * lib/bitsetv.c (bitsetv_alloc): Likewise.
17190
17191 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
17192 unique names for structures.
17193 * lib/ebitset.c (ebitset_bytes): Likewise.
17194 * lib/lbitset.c (lbitset_bytes): Likewise.
17195
17196 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
17197 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
17198 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

17201 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
17202 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
17203 to improve the type-checking that GCC can do.
17204 * lib/bitset.c (bitset_op4_cmp): Likewise.
17205 * lib/bitset_stats.c (bitset_stats_count,
17206 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
17207 bitset_stats_copy, bitset_stats_disjoint_p,

17213 bitset_stats_andn_or_cmp, bitset_stats_or_and,
17214 bitset_stats_or_and_cmp): Likewise.
17215 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
17216 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
17217 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
17218 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
17219
17220 * lib/abitset.h: Include bitset.h, not bbitset.h.
17221 * lib/ebitset.h: Likewise.
17222 * lib/lbitset.h: Likewise.
17223
17224 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
17225 All instances of parameters of type enum bitset_opts are now of
17226 type enum_bitset_opts, to conform to the C Standard, and similarly
17227 for enum_bitset_type.
17228 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17229 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
17230
17231 Do not use "struct bitset_struct" to mean different things in
17232 different modules. Not only is this confusing, it violates
17233 the C Standard, which requires that structure types in different
17234 modules must be compatible if one is to be passed to the other.
17235 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
17236 All instances of "struct bitset_struct *" replaced with "bitset".
17237 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
17238 (union bitset_union, struct abitset_struct, struct ebitset_struct,
17239 struct lbitset_struct, struct bitset_stats_struct): New types.
17240 All uses of struct bitset_struct changed to union bitset_union,
17241 etc.
17242 * lib/abitset.c (struct abitset_struct, abitset,
17243 struct bitset_struct): Remove.
17244 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
17245 struct bitset_struct): Remove.
17246 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
17247 bitset_struct): Remove.
17248 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
17249 Likewise.
17250
17251 Do not call a function of type T using a call that assumes the
17252 function is of a different type U. Standard C requires that a
17253 function must be called with a type that is compatible with its
17254 definition.
17255 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17256 New decls.
17257 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17258 New functions.
17259 * lib/ebitset.c (PFV): Remove.
17260 * lib/lbitset.c (PFV): Likewise.
17261 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
17262 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
17263 decls.
17264 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
17265 (ebitset_vtable): Use them.
17266 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
17267 lbitset_xor): New functions.
17268 (lbitset_vtable): Use them.
17269
17270 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
17271 Declare.
17272
17273 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
17274 GCC warning.
17275 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
17276 Use offsetof, for simplicity.
17277
17278 2002-10-06 Paul Eggert <eggert@twinsun.com>
17279
17280 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
17281 the same width as int. This reapplies a hunk of the 2002-08-12 patch
17282 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
17283 which was inadvertently undone by the 2002-09-30 patch.
17284 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
17285 the same width as int.
17286
17287 2002-10-04 Paul Eggert <eggert@twinsun.com>
17288
17289 Version 1.50.
17290
17291 * configure.ac (AC_INIT), NEWS: Increment version number.
17292
17293 * doc/bison.texinfo: Minor spelling, grammar, and white space
17294 fixes.
17295 (Symbols): Mention that any negative value returned from yylex
17296 signifies end-of-input. Warn about negative chars. Mention
17297 the portable Standard C character set.
17298
17299 The GNU coding standard says CFLAGS and YFLAGS are reserved
17300 for the installer to set.
17301 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
17302 * src/Makefile.am (AM_CFLAGS): Likewise.
17303 (AM_YFLAGS): Renamed from YFLAGS.
17304
17305 Fix some MAX and MIN problems.
17306 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
17307 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
17308 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
17309 * src/reader.c (reader): Use it.
17310
17311 * tests/regression.at (Braces parsing): Use grep, not fgrep, as

17384 BITSET_SIZE_MAX): New macros.
17385 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
17386 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
17387 to BITSET_WINDEX_MAX.
17388
17389 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
17390 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

17490
17491 * doc/bison.texinfo (Conditions): Make explicit that the GPL
17492 exception applies only to yacc.c. This is a modification of a

17496

17499 * data/yacc.c: here.
17500
17501 * data/lalr1.cc (struct yyltype): Don't define it, since we use
17502 LocationType.
17503 (b4_ltype): Default to yy::Location from location.hh.
17504
17505 2002-09-04 Jim Meyering <jim@meyering.net>
17506
17507 * data/yacc.c: Guard the declaration of yytoknum also with
17508 `#ifdef YYPRINT', so it is declared only when used.
17509
17510 2002-09-04 Akim Demaille <akim@epita.fr>
17511
17512 * configure.in: Rename as...
17513 * configure.ac: this.

17515
17516 2002-09-04 Akim Demaille <akim@epita.fr>
17517
17518 * src/assoc.c, src/closure.c, src/gram.c, src/injections.c,
17519 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't

17525
17526 * Makefile.am (SUBDIRS): Remove intl.
17527 (DISTCLEANFILES): Remove.
17528 * NEWS: Mention that GNU M4 is now required. Clarify what is

17539 * data/glr.c: Include string.h, for strlen.
17540 (yyreportParseError): Use size_t for yysize.
17541 (yy_yypstack): No longer nested inside yypstates, as nested
17542 functions are not portable. Do not assume size_t is the
17543 same width as int.
17544 (yypstates): Do not assume that ptrdiff_t is the same width
17545 as int, and similarly for yyposn and YYINDEX.
17546
17547 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
17548
17549 * lib/Makefile.am (INCLUDES): Do not include from the intl
17550 directory, which has been removed.
17551 * src/Makefile.am (INCLUDES): Likewise.

17559
17560 * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):
17561 Do not assume that bitset_windex is the same width as unsigned.
17562
17563 * lib/abitset.c (abitset_unused_clear): Do not assume that
17564 bitset_word is the same width as int.

17581 lib/gettext.h: Sync with diffutils.
17582
17583 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
17584 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
17585
17586 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
17587 PROTOTYPES to check for prototypes, and "defined __STDC__" to
17588 check for void *.
17589
17590 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
17591 size_t; the old version tried to do this but casted improperly.
17592 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
17593 (bitset_test): Now returns int, not unsigned long.
17594
17595 * lib/bitset_stats.c: Include "gettext.h".
17596 (_): New macro.
17597 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
17598 name locals "index", as it generates unnecessary warnings on some
17599 hosts that have an "index" function.
17600
17601 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
17602 bitset_stats_read, bitset_stats_write): Wrap strings in _() if
17603 they need translation.
17604 * src/LR0.c (state_list_append, new_itemsets, get_state,
17605 append_states, generate_states): Likewise.
17606 * src/assoc.c (assoc_to_string): Likewise.
17607 * src/closure.c (print_closure, set_firsts, closure): Likewise.
17608 * src/gram.c (grammar_dump): Likewise.

17623 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
17624 lib/timevar.c.
17625 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
17626 manual recommends.
17627 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
17628
17629 * src/complain.c (strerror_r): Remove decl; not needed.
17630 (strerror): Use same pattern as ../lib/error.c.
17631
17632 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
17633
17634 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
17635
17636 * src/main.c (main): Cast result of bindtextdomain and textdomain
17637 to void, to avoid a GCC warning when --disable-nls is in effect.
17638
17639 * src/scan-gram.l: Use strings rather than escapes when possible,
17640 to minimize the number of warnings from xgettext.
17641 (handle_action_dollar, handle_action_at): Don't use isdigit,
17642 as it mishandles negative chars and it may not work as expected
17643 outside the C locale.
17644
17645 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
17646 this is a GCC extension and is not portable to other compilers.
17647
17648 * src/system.h (alloca): Use same pattern as ../lib/error.c.
17649 Do not include <ctype.h>; no longer needed.
17650 Do not include <malloc.h>; no longer needed (and generates
17651 warnings on OpenBSD 3.0).
17652
17653 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
17654 it's not portable.
17655
17656 * tests/regression.at: Do not use 'cc -c input.c -o input';
17657 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
17658
17659 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
17660 exit status as failure, not just exit status 1. Sun C exits
17661 with status 2 sometimes.
17662
17663 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
17664 Use it for the two large tests.
17665
17666 2002-08-02 Akim Demaille <akim@epita.fr>
17667
17668 * src/conflicts.c (conflicts_output): Don't output rules never
17669 reduced here, since anyway that computation doesn't work.
17670 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
17671 (rule_useless_p, rule_never_reduced_p): New.
17672 (grammar_rules_partial_print): Use a filter instead of a range.
17673 Display the title only if needed.
17674 (grammar_rules_print): Adjust.
17675 (grammar_rules_never_reduced_report): New.
17676 * src/tables.c (action_row): Move the computation of rules never
17677 reduced to...
17678 (token_actions): here.
17679 * src/main.c (main): Make the parser before making the report, so
17680 that rules never reduced are computed.
17681 Call grammar_rules_never_reduced_report.
17682 * src/print.c (print_results): Report rules never reduced.
17683 * tests/conflicts.at, tests/reduce.at: Adjust.
17684
17685 2002-08-01 Akim Demaille <akim@epita.fr>
17686
17687 Instead of attaching lookaheads and duplicating the rules being
17688 reduced by a state, attach the lookaheads to the reductions.
17689
17690 * src/state.h (state_t): Remove the `lookaheads',
17691 `lookaheads_rule' member.
17692 (reductions_t): Add a `lookaheads' member.
17693 Use a regular array for the `rules'.
17694 * src/state.c (reductions_new): Initialize the lookaheads member
17695 to 0.
17696 (state_rule_lookaheads_print): Adjust.
17697 * src/state.h, src/state.c (state_reductions_find): New.
17698 * src/conflicts.c (resolve_sr_conflict, set_conflicts)
17699 (count_rr_conflicts): Adjust.
17700 * src/lalr.c (LArule): Remove.
17701 (add_lookback_edge): Adjust.
17702 (state_lookaheads_count): New.

17723 as they were lo longer used.
17724
17725 2002-08-01 Akim Demaille <akim@epita.fr>
17726
17727 * lib/timevar.c (get_time): Include children time.

17778 * src/main.c (stage): Remove.
17779 (main): Replace `stage' invocations with timevar calls.
17780 * src/output.c: Insert pertinent timevar calls.
17781
17782 2002-07-31 Akim Demaille <akim@epita.fr>

17787 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
17788 (long_options, short_options): --trace/-T takes an optional
17789 argument.
17790 Change all the uses of trace_flag to reflect the new flags.
17791 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.

17825 by conflicts.
17826
17827 * src/LR0.c (save_reductions): Don't make the final state too
17828 different: save its reduction (accept) instead of having a state
17829 without any action (no shift or goto, no reduce).
17830 Note: the final state is now a ``regular'' state, i.e., the
17831 parsers now contain `reduce 0' as default reduction.
17832 Nevertheless, since they decide to `accept' when yystate =
17833 final_state, they still will not reduce rule 0.
17834 * src/print.c (print_actions, print_reduction): Adjust.
17835 * src/output.c (action_row): Track reduced rules.
17836 (token_actions): Report rules never reduced.

17870
17871 * src/reduce.c (reduce_grammar): When the language is empty,
17872 complain about the start symbol, not the axiom.
17873 Use its location.
17874 * tests/reduce.at (Empty Language): New.
17875
17876 2002-07-26 Akim Demaille <akim@epita.fr>
17877
17878 * src/reader.h, src/reader.c (gram_error): ... can't get
17879 yycontrol without making too strong assumptions on the parser
17880 itself.
17881 * src/output.c (prepare_tokens): Use the real 0th value of
17882 token_translations instead of `0'.
17883 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
17884 visible here.
17885 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
17886 for the time being: %locations ought to provide it to yyerror.

17888 2002-07-25 Akim Demaille <akim@epita.fr>
17889
17890 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

17899 * src/nullable.c, src/output.c, src/print.c, src/reader.c
17900 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].

17903 Adjust to `derive' now containing possibly 0.

18965 stricter %token grammar.

19050
19051 Remove `%thong' support as it is undocumented, unused, duplicates
19052 `%token's job, and creates useless e-mail traffic with people who
19053 want to know what it is, why it is undocumented, unused, and
19054 duplicates `%token's job.
19055
19056 * src/reader.c (parse_thong_decl): Remove.

19394
19395 * configure.in (ALL_LINGUAS): Remove.

19426 `rule_length', which is more readable.
19427 Adjust callers.

19429 values of $$, $n and so forth, output invocation to b4_lhs_value,
19430 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
19431 Note: this patch partially drops `semantic-parser' support: it
19432 always does `rule_length - n', where semantic parsers ought to
19433 always use `-n'.
19434 * data/bison.simple, data/bison.c++ (b4_lhs_value)
19435 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

19464
19465 * src/reader.c (copy_character): New function, used to output
19466 single characters while replacing `[' and `]' with quadrigraphs, to
19467 avoid troubles with M4 quotes.

19479 Reported by Paul Eggert.
19480
19481 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
19482
19483 * tests/calc.at: Exercise prologue splitting.
19484
19485 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
19486 `b4_post_prologue' instead of `b4_prologue'.
19487
19488 * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
19489 muscles.
19490 (output): Free pre_prologue_obstack and post_prologue_obstack.

19496 `%union' has not yet been seen, pass post_prologue_obstack otherwise.
19497
19498 2002-04-23 Paul Eggert <eggert@twinsun.com>
19499
19500 * data/bison.simple: Remove unnecessary commentary and white
19501 space differences from 1_29-branch.
19502 Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
19503
19504 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
19505 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
19506 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

19537
19538 2002-04-22 Akim Demaille <akim@epita.fr>
19539
19540 * src/reader.c (token_translations_init): 256 is now the default
19541 value for the error token, i.e., it will be assigned another
19542 number if the user assigned 256 to one of her tokens.
19543 (reader): Don't force 256 to error.
19544 * doc/bison.texinfo (Symbols): Adjust.
19545 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
19546 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
19547 etc. instead of 10, 20, 30 (which was used to `jump' over error

19549
19550 2002-04-22 Akim Demaille <akim@epita.fr>
19551
19552 Propagate more token_number_t.

19555 (item_number_as_token_number): New.
19556 * src/output.c (GENERATE_OUTPUT_TABLE): New.

19569
19570 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
19571 as Lex/Flex'.
19572 (Debugging): More details about enabling the debugging features.
19573 (Table of Symbols): Describe $$, $n, @$, and @n.
19574 Suggested by Tim Josling.
19575
19576 2002-04-19 Akim Demaille <akim@epita.fr>
19577
19578 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
19579
19580 2002-04-10 Akim Demaille <akim@epita.fr>

19584
19585 2002-04-09 Akim Demaille <akim@epita.fr>
19586
19587 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
19588 full stderr, and strip it according to the bison options, instead
19589 of composing the error message from different bits.
19590 This makes it easier to check for several error messages.
19591 Adjust all the invocations.
19592 Add an invocation exercising the error token.
19593 Add an invocation demonstrating a stupid error message.
19594 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
19595 Adjust the tests.
19596 Error message are for stderr, not stdout.

19600 * src/gram.h, src/gram.c (error_token_number): Remove, use
19601 errtoken->number.
19602 * src/reader.c (reader): Don't specify the user token number (2)
19603 for $undefined, as it uselessly prevents using it.
19604 * src/gram.h (token_number_t): Move to...
19605 * src/symtab.h: here.
19606 (state_t.number): Is a token_number_t.
19607 * src/print.c, src/reader.c: Use undeftoken->number instead of
19608 hard coded 2.
19609 (Even though this 2 is not the same as above: the number of the
19610 undeftoken remains being 2, it is its user token number which
19611 might not be 2).
19612 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
19613 `user_token_number_max'.
19614 Output `undef_token_number'.
19615 * data/bison.simple, data/bison.c++: Use them.
19616 Be sure to map invalid yylex return values to
19617 `undef_token_number'. This saves us from gratuitous SEGV.

19620 (Unresolved SR Conflicts): Adjust.
19621 * tests/regression.at (Web2c Actions): Adjust.

19629 Use __ofile__.
19630 * data/bison.simple: Use __ofile__.

19634
19635 * src/gram.h (item_number_t): New, the type of item numbers in
19636 RITEM. Note that it must be able to code symbol numbers as
19637 positive number, and the negation of rule numbers as negative
19638 numbers.
19639 Adjust all dependencies (pretty many).
19640 * src/reduce.c (rule): Remove this `short *' pointer: use
19641 item_number_t.
19642 * src/system.h (MINSHORT, MAXSHORT): Remove.
19643 Include `limits.h'.
19644 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
19645 (shortcpy): Remove.
19646 (MAXTABLE): Move to...
19647 * src/output.c (MAXTABLE): here.

19650 * tests/torture.at (Big triangle): Move the limit from 254 to
19651 500.
19652 * tests/regression.at (Web2c Actions): Ajust.
19653
19654 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
19655 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
19656 passes, but produces negative #line number, once fixed, GCC is
19657 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
19658 C), it passes.
19659 * src/state.h (state_h): Code input lines on ints, not shorts.
19660

19675 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
19676 New.
19677 Use them to define yy_token_number_type/TokenNumberType.

19680 253.
19681 * tests/regression.at (Web2c Actions): Adjust.

19751 2002-04-07 Akim Demaille <akim@epita.fr>
19752
19753 * src/gram.h (rule_s): prec and precsym are now pointers
19754 to the bucket giving the priority/associativity.
19755 Member `associativity' removed: useless.
19756 * src/reduce.c, src/conflicts.c: Adjust.

19780 2002-04-07 Akim Demaille <akim@epita.fr>
19781
19782 As a result of the previous patch, it is no longer needed
19783 to reorder ritem itself.
19784
19785 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
19786
19787 2002-04-07 Akim Demaille <akim@epita.fr>
19788
19789 Be sure never to walk through RITEMS, but use only data related to
19790 the rules themselves. RITEMS should be banished.
19791
19792 * src/output.c (output_token_translations): Rename as...
19793 (prepare_tokens): this.
19794 In addition to `translate', prepare the muscles `tname' and

19796 (output_rule_data): this.
19797 Remove, and move the remainder of its outputs into...
19798 (prepare_rules): this new routines, which also merges content from

19801 (output_stos): Rename as...

19810 Adjust to initialize first_state and last_state if needed.
19811 Be sure to distinguish the initial from the final state.
19812 (new_states): Create the itemset of the initial state, and use
19813 new_state.
19814 * src/closure.c (closure): Now that the initial state has its
19815 items properly set, there is no need for a special case when
19816 creating `ruleset'.
19817
19818 As a result, now the rule 0, reducing to $axiom, is visible in the
19819 outputs. Adjust the test suite.
19820
19821 * tests/conflicts.at (Solved SR Conflicts)
19822 (Unresolved SR Conflicts): Adjust.
19823 * tests/regression.at (Web2c Report, Rule Line Numbers): Idem.

19832 2002-04-07 Akim Demaille <akim@epita.fr>

19835 bucket.
19836 Adjust all dependencies.
19837 * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
19838 `number' of the buckets too.
19839 * src/gram.h: Include `symtab.h'.
19840 (associativity): Move to...
19841 * src/symtab.h: here.
19842 No longer include `gram.h'.

19850 * src/reduce.c (reduce_grammar_tables): Move the useless rules at
19851 the end of `rules', and count them out of `nrules'.
19852 (reduce_output, dump_grammar): Adjust.
19853 * src/print.c (print_grammar): It is no longer needed to check for
19854 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

19856
19857 2002-04-07 Akim Demaille <akim@epita.fr>
19858
19859 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
19860 lacking `+ 1' to nrules, Bison reported as useless a token if it
19861 was used solely to set the precedence of the last rule...
19862
19863 2002-04-07 Akim Demaille <akim@epita.fr>
19864
19865 * data/bison.c++, data/bison.simple: Don't output the current file
19866 name in #line, to avoid useless diffs between two identical
19867 outputs under different names.
19868
19869 2002-04-07 Akim Demaille <akim@epita.fr>
19870

19886 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
19887 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
19888 RHS, instead of being an index in RITEMS.

20206 * data/bison.c++: Replace some direct m4 expansions by constants. Be
20207 more consistent when naming methods and variables. Put preprocessor
20208 directives around tables only needed for debugging.
20209
20210 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20211
20212 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
20213 C++ parsers.
20214 (yy::b4_name::parse): Use print_.
20215
20216 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20217
20218 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
20219
20220 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20221
20222 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
20223 C++ parsers.
20224 (yy::b4_name::parse): Build verbose error messages, and use error_.
20225
20226 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
20227
20228 * data/bison.c++: Fix m4 quoting in comments.
20229
20230 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
20231
20232 * data/bison.c++: Adjust the parser code. Fix some muscles that were
20233 not expanded by m4.
20234
20235 2002-02-05 Akim Demaille <akim@epita.fr>
20236
20237 * data/bison.c++: Adjust to the M4 back end.
20238 More is certainly needed.
20239
20240 2002-02-05 Akim Demaille <akim@epita.fr>
20241
20242 Give a try to M4 as a back end.
20243
20244 * lib/readpipe.c: New, from wdiff.
20245 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
20246 BISON_HAIRY.
20247 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
20248 specific values. Now it is m4 that performs the lookup.
20249 * src/parse-skel.y: Remove.
20250 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
20251 * src/output.c (actions_output, guards_output)
20252 (token_definitions_output): No longer keeps track of the output
20253 line number, hence remove the second argument.
20254 (guards_output): Check against the guard member of a rule, not the
20255 action member.
20256 Adjust callers.
20257 (output_skeleton): Don't look for the skeleton location, let m4 do
20258 that.
20259 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
20260 file will be used.
20261 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
20262 (prepare): Given that for the time being changesyntax is not
20263 usable in M4, rename the muscles using `-' to `_'.
20264 Define `defines_flag', `output_parser_name' and `output_header_name'.
20265 * src/output.h (actions_output, guards_output)
20266 (token_definitions_output): Adjust prototypes.
20267 * src/scan-skel.l: Instead of scanning the skeletons, it now
20268 processes the output of m4: `__oline__' and `#output'.
20269 * data/bison.simple: Adjust to be used by M4(sugar).
20270 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
20271 to date.
20272 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
20273 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
20274 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
20275 shamelessly stolen from CVS Autoconf.
20276
20277 2002-02-05 Akim Demaille <akim@epita.fr>
20278
20279 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
20280 * configure.in: Check for the declarations of free and malloc.
20281 * src/muscle_tab.c: Adjust.
20282
20283 2002-02-05 Akim Demaille <akim@epita.fr>
20284
20285 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
20286 which have no values.
20287
20288 2002-02-05 Akim Demaille <akim@epita.fr>
20289
20290 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
20291 * data/: here.
20292
20293 2002-01-29 Paul Eggert <eggert@twinsun.com>
20294
20295 * src/bison.simple (YYSIZE_T): Do not define merely because
20296 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
20297 On some platforms, <alloca.h> does not declare YYSTD (size_t).
20298
20299 2002-01-27 Akim Demaille <akim@epita.fr>
20300
20301 Fix `%nonassoc and eof'.
20302
20303 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
20304 which were not properly copied! Replace
20305 memcpy (res->errs, src->errs, src->nerrs);
20306 with
20307 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
20308 !!!
20309 * tests/regression.at (%nonassoc and eof): Adjust to newest
20310 Autotest: `.' is not in the PATH.
20311
20312 2002-01-27 Akim Demaille <akim@epita.fr>
20313
20314 * tests/sets.at (AT_EXTRACT_SETS): New.
20315 (Nullable): Use it.
20316 (Firsts): New.
20317
20318 2002-01-26 Akim Demaille <akim@epita.fr>
20319
20320 * tests/actions.at, tests/calc.at, tests/headers.at,
20321 * tests/torture.at: Adjust to the newest Autotest which no longer
20322 forces `.' in the PATH.
20323
20324 2002-01-25 Akim Demaille <akim@epita.fr>
20325
20326 * tests/regression.at (%nonassoc and eof): New.
20327 Suggested by Robert Anisko.
20328
20329 2002-01-24 Akim Demaille <akim@epita.fr>
20330
20331 Bison dumps core when trying to complain about broken input files.
20332 Reported by Cris van Pelt.
20333
20334 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
20335 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
20336 into...
20337 (Invalid inputs): Strengthen: exercise parse_percent_token.
20338
20339 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
20340
20341 * src/Makefile.am: Add bison.c++.
20342 * src/bison.c++: New skeleton.
20343
20344 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
20345
20346 * po/it.po: New.
20347
20348 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
20349
20350 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
20351
20352 2002-01-20 Marc Autret <marc@gnu.org>
20353
20354 * src/files.c (compute_output_file_names): Fix
20355
20356 2002-01-20 Marc Autret <marc@gnu.org>
20357
20358 * tests/output.at: New test.
20359 * src/files.c (compute_base_names): Don't map extensions when
20360 the YACC flag is set, use defaults.
20361 Reported by Evgeny Stambulchik.
20362
20363 2002-01-20 Marc Autret <marc@gnu.org>
20364
20365 * src/system.h: Need to define __attribute__ away for non-GCC
20366 compilers as well (i.e., the vendor C compiler).
20367 Suggested by Albert Chin-A-Young.
20368
20369 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
20370
20371 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
20372 canonical definition.
20373 * src/system.h: Use the canonical definition for PARAMS (avoids
20374 a conflict with the macro from lib/hash.h).
20375
20376 2002-01-11 Akim Demaille <akim@epita.fr>
20377
20378 * configure.in: Use AC_FUNC_STRNLEN.
20379 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
20380
20381 2002-01-09 Akim Demaille <akim@epita.fr>
20382
20383 * src/files.c, src/files.h (output_infix): New.
20384 (tab_extension): Remove.
20385 (compute_base_names): Compute the former, drop the latter.
20386 * src/output.c (prepare): Insert the muscles `output-infix', and
20387 `output-suffix'.
20388 * src/parse-skel.y (string, string.1): New.
20389 (section.header): Use it.
20390 (section.yacc): Remove.
20391 (prefix): Remove too.
20392 * src/scan-skel.l: Adjust.
20393 * src/bison.simple, src/bison.hairy: Adjust.
20394
20395 2002-01-09 Akim Demaille <akim@epita.fr>
20396
20397 * configure.in (WERROR_CFLAGS): Compute it.
20398 * src/Makefile.am (CFLAGS): Pass it.
20399 * tests/atlocal.in (CFLAGS): Idem.
20400 * src/files.c: Fix a few warnings.
20401 (get_extension_index): Remove, unused.
20402
20403 2002-01-08 Akim Demaille <akim@epita.fr>
20404
20405 * src/getargs.c (AS_FILE_NAME): New.
20406 (getargs): Use it to convert DOSish file names.
20407 * src/files.c (base_name): Rename as full_base_name to avoid
20408 clashes with `base_name ()'.
20409 (filename_split): New.
20410 (compute_base_names): N-th rewrite, using filename_split.
20411
20412 2002-01-08 Akim Demaille <akim@epita.fr>
20413
20414 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
20415 New, stolen from the Fileutils 4.1.
20416 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
20417 * configure.in: Check for the presence of memrchr, and of its
20418 prototype.
20419
20420 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
20421
20422 * lib/hash.h (__P): Added definition for this macro.
20423 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
20424 BUILT_SOURCES, to ensure they are generated first.
20425 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
20426 %error-verbose to allow bootstrapping with bison 1.30x.
20427
20428 2002-01-06 Akim Demaille <akim@epita.fr>
20429
20430 * src/reader.c (parse_braces): Don't fetch the next char, the
20431 convention is to fetch on entry.
20432 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
20433 'switch' without a following semicolon.
20434 * tests/regression.at (braces parsing): New.
20435
20436 2002-01-06 Akim Demaille <akim@epita.fr>
20437
20438 Bison is dead wrong in its RR conflict reports.
20439
20440 * tests/torture.at (GNU Cim Grammar): New.
20441 * src/conflicts.c (count_rr_conflicts): Fix.
20442
20443 2002-01-06 Akim Demaille <akim@epita.fr>
20444
20445 Creating package.m4 from configure.ac causes too many problems.
20446
20447 * tests/Makefile.am (package.m4): Create it by hand,
20448 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
20449
20450 2002-01-06 Akim Demaille <akim@epita.fr>
20451
20452 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
20453 skeleton.h.
20454
20455 2002-01-04 Paul Eggert <eggert@twinsun.com>
20456
20457 * doc/bison.texinfo (Debugging):
20458 Remove YYSTDERR; it's no longer defined or used.
20459 Also, s/cstdio.h/cstdio/.
20460
20461 2002-01-03 Akim Demaille <akim@epita.fr>
20462
20463 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
20464
20465 2002-01-03 Akim Demaille <akim@epita.fr>
20466
20467 * src/parse-skel.y (process_skeleton): Don't bind the parser's
20468 tracing code to --trace, wait for a better --trace option, with
20469 args.
20470
20471 2002-01-03 Akim Demaille <akim@epita.fr>
20472
20473 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
20474 The ISO C++ standard is extremely clear about it: stderr is
20475 considered a macro, not a regular symbol (see table 94 `Header
20476 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
20477 Therefore std:: does not apply to it. It still does with fprintf.
20478 Also, s/cstdio.h/cstdio/.
20479
20480 2002-01-03 Akim Demaille <akim@epita.fr>
20481
20482 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
20483 for non system headers.
20484
20485 2002-01-02 Akim Demaille <akim@epita.fr>
20486
20487 Equip the skeleton chain with location tracking, runtime trace,
20488 pure parser and scanner.
20489
20490 * src/parse-skel.y: Request a pure parser, locations, and prefix
20491 renaming.
20492 (%union): Having several members with the same type does not help
20493 type mismatches, simplify.
20494 (YYPRINT, yyprint): New.
20495 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
20496 (skel_error): this.
20497 Handle locations.
20498 * src/scan-skel.l: Adjust to these changes.
20499 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
20500 (LOCATION_PRINT, skel_control_t): New.
20501
20502 2001-12-30 Akim Demaille <akim@epita.fr>
20503
20504 * src/parse-skel.y: Get rid of the shift/reduce conflict:
20505 replace `gb' with BLANKS.
20506 * src/scan-skel.l: Adjust.
20507
20508 2001-12-30 Akim Demaille <akim@epita.fr>
20509
20510 * src/system.h: We don't need nor want bcopy.
20511 Throw away MS-DOS crap: we don't need getpid.
20512 * configure.in: We don't need strndup. It was even causing
20513 problems: because Flex includes the headers *before* us,
20514 _GNU_SOURCE is not defined by config.h, and therefore strndup was
20515 not visible.
20516 * lib/xstrndup.c: New.
20517 * src/scan-skel.l: Use it.
20518 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
20519 * src/parse-skel.y: Use %directives instead of #defines.
20520
20521 2001-12-30 Akim Demaille <akim@epita.fr>
20522
20523 * src/skeleton.h: New.
20524 * src/output.c (output_parser, output_master_parser): Remove, dead
20525 code.
20526 * src/output.h (get_lines_number, actions_output, guards_output)
20527 (token_definitions_output): Prototype them.
20528 * src/parse-skel.y: Add the license notice.
20529 Include output.h and skeleton.h.
20530 (process_skeleton): Returns void, and takes a single parameter.
20531 * src/scan-skel.l: Add the license notice.
20532 Include skeleton.h.
20533 Don't use %option yylineno: it seems that then Flex imagines
20534 REJECT has been used, and therefore it won't reallocate its
20535 buffers (which makes no other sense to me than a bug). It results
20536 in warnings for `unused: yy_flex_realloc'.
20537
20538 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
20539
20540 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
20541 (MUSCLE_INSERT_PREFIX): ...to there.
20542 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
20543 (MUSCLE_INSERT_PREFIX): Move from here...
20544
20545 * src/bison.hairy: Add a section directive. Put braces around muscle
20546 names. This parser skeleton is still broken, but Bison should not
20547 choke on a bad muscle 'syntax'.
20548 * src/bison.simple: Add a section directive. Put braces around muscle
20549 names.
20550
20551 * src/files.h (strsuffix, stringappend): Add declarations.
20552 (tab_extension): Add declaration.
20553 (short_base_name): Add declaration.
20554
20555 * src/files.c (strsuffix, stringappend): No longer static. These
20556 functions are used in the skeleton parser.
20557 (tab_extension): New.
20558 (compute_base_names): Use the computations done in this function
20559 to guess if the generated parsers should have '.tab' in their
20560 names.
20561 (short_base_name): No longer static.
20562
20563 * src/output.c (output_skeleton): New.
20564 (output): Disable call to output_master_parser, and give a try to
20565 a new skeleton handling system.
20566 (guards_output, actions_output): No longer static.
20567 (token_definitions_output, get_lines_number): No longer static.
20568
20569 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
20570
20571 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
20572 parse-skel.y.
20573
20574 * src/parse-skel.y: New file.
20575 * src/scan-skel.l: New file.
20576
20577 2001-12-29 Akim Demaille <akim@epita.fr>
20578
20579 %name-prefix is broken.
20580
20581 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
20582 Adjust all dependencies.
20583 * tests/headers.at (export YYLTYPE): Strengthen this test: use
20584 %name-prefix.
20585
20586 Renaming yylval but not yylloc is not consistent. Now we do.
20587
20588 * src/bison.simple: Prefix yylloc if used.
20589 * doc/bison.texinfo (Decl Summary): Document that.
20590
20591 2001-12-29 Akim Demaille <akim@epita.fr>
20592
20593 * doc/bison.texinfo: Promote `%long-directive' over
20594 `%long_directive'.
20595 Remove all references to fixed-output-files, yacc is enough.
20596
20597 2001-12-29 Akim Demaille <akim@epita.fr>
20598
20599 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
20600 user prologue. These are defaults.
20601 * tests/actions.at (Mid-rule actions): Make sure the user can
20602 define YYDEBUG and YYERROR_VERBOSE.
20603
20604 2001-12-29 Akim Demaille <akim@epita.fr>
20605
20606 * src/output.c (header_output): Don't forget to export YYLTYPE and
20607 yylloc.
20608 * tests/headers.at (export YYLTYPE): New, make sure it does.
20609 * tests/regression.at (%union and --defines, Invalid CPP headers):
20610 Move to...
20611 * tests/headers.at: here.
20612
20613 2001-12-29 Akim Demaille <akim@epita.fr>
20614
20615 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
20616
20617 2001-12-29 Akim Demaille <akim@epita.fr>
20618
20619 * tests/actions.at (Mid-rule actions): Output on a single line
20620 instead of several.
20621
20622 2001-12-29 Akim Demaille <akim@epita.fr>
20623
20624 * doc/bison.texinfo: Formatting changes.
20625
20626 2001-12-29 Akim Demaille <akim@epita.fr>
20627
20628 Don't store the token defs in a muscle, just be ready to output it
20629 on command. Now possible via `symbols'. Fixes a memory leak.
20630
20631 * src/output.c (token_definitions_output): New.
20632 (output_parser, header_output): Use it.
20633 * src/reader.c (symbols_save): Remove.
20634
20635 2001-12-29 Akim Demaille <akim@epita.fr>
20636
20637 * src/bison.simple: Do not provide a default for YYSTYPE and
20638 YYLTYPE before the user's prologue. Otherwise it's hardly... a
20639 default.
20640
20641 2001-12-29 Akim Demaille <akim@epita.fr>
20642
20643 Mid-rule actions are simply... ignored!
20644
20645 * src/reader.c (readgram): Be sure to attach mid-rule actions to
20646 the empty-rule associated to the dummy symbol, not to the host
20647 rule.
20648 * tests/actions.at (Mid-rule actions): New.
20649
20650 2001-12-29 Akim Demaille <akim@epita.fr>
20651
20652 Memory leak.
20653
20654 * src/reader.c (reader): Free grammar.
20655
20656 2001-12-29 Akim Demaille <akim@epita.fr>
20657
20658 Memory leak.
20659
20660 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
20661 since it allocates it for each state, although only one is needed.
20662 (allocate_storage): Do it here.
20663
20664 2001-12-29 Akim Demaille <akim@epita.fr>
20665
20666 * src/options.h, src/options.c (create_long_option_table): Rename
20667 as...
20668 (long_option_table_new): this, with a clearer prototype.
20669 (percent_table): Remove, unused,
20670 * src/getargs.c (getargs): Adjust.
20671
20672 2001-12-29 Akim Demaille <akim@epita.fr>
20673
20674 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
20675 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
20676 as states.
20677
20678 2001-12-29 Akim Demaille <akim@epita.fr>
20679
20680 * src/lalr.c (build_relations): Rename `states' as `states1'.
20681 Sorry, I don't understand exactly what it is, no better name...
20682
20683 2001-12-29 Akim Demaille <akim@epita.fr>
20684
20685 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
20686 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
20687 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
20688 as rules.
20689
20690 2001-12-29 Akim Demaille <akim@epita.fr>
20691
20692 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
20693 ago.
20694
20695 2001-12-29 Akim Demaille <akim@epita.fr>
20696
20697 * src/reader.c, src/reader.h (user_toknums): Remove.
20698 Adjust all users to use symbols[i]->user_token_number.
20699
20700 2001-12-29 Akim Demaille <akim@epita.fr>
20701
20702 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
20703 Adjust all users to use symbols[i]->prec or ->assoc.
20704
20705 2001-12-29 Akim Demaille <akim@epita.fr>
20706
20707 * src/reader.c, src/reader.h (tags): Remove.
20708 Adjust all users to use symbols[i]->tag.
20709
20710 2001-12-29 Akim Demaille <akim@epita.fr>
20711
20712 * src/gram.h, src/gram.c (symbols): New, similar to state_table
20713 and rule_table.
20714 * src/reader.c (packsymbols): Fill this table.
20715 Drop sprec.
20716 * src/conflicts.c (resolve_sr_conflict): Adjust.
20717 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
20718 single table.
20719 Use symbols[i]->tag instead of tags[i].
20720
20721 2001-12-29 Akim Demaille <akim@epita.fr>
20722
20723 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
20724 In addition, put a comment in there, to replace...
20725 * tests/regression.at (%union and C comments): Remove.
20726
20727 2001-12-29 Akim Demaille <akim@epita.fr>
20728
20729 * tests/regression.at (Web2c Actions): Blindly move the actual
20730 output as expected output. The contents *seem* right to me, but I
20731 can't pretend reading perfectly parser tables... Nonetheless, all
20732 the other tests pass correctly, the table look OK, even though the
20733 presence of `$axiom' is to be noted: AFAICS it is useless (but
20734 harmless).
20735
20736 2001-12-29 Akim Demaille <akim@epita.fr>
20737
20738 * src/reader.c (readgram): Don't add the rule 0 if there were no
20739 rules read. In other words, add it _after_ having performed
20740 grammar sanity checks.
20741 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
20742
20743 2001-12-29 Akim Demaille <akim@epita.fr>
20744
20745 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
20746 visible, and some states have now a different number.
20747
20748 2001-12-29 Akim Demaille <akim@epita.fr>
20749
20750 * src/reader.c (readgram): Bind the initial rule's lineno to that
20751 of the first rule.
20752 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
20753 (Solved SR Conflicts): Adjust rule 0's line number.
20754
20755 2001-12-29 Akim Demaille <akim@epita.fr>
20756
20757 Fix the `GAWK Grammar' failure.
20758
20759 * src/LR0.c (final_state): Initialize to -1 so that we do compute
20760 the reductions of the first state which was mistakenly confused
20761 with the final state because precisely final_state was initialized
20762 to 0.
20763 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
20764 now noticed by Bison.
20765 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
20766 have a reduction on $default.
20767
20768 2001-12-29 Akim Demaille <akim@epita.fr>
20769
20770 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
20771 rule line numbers.
20772 * src/closure.c (print_closure): Likewise.
20773 * src/derives.c (print_derives): Likewise.
20774 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
20775 now.
20776
20777 2001-12-29 Akim Demaille <akim@epita.fr>
20778
20779 * src/lalr.c (lookaheads_print): New.
20780 (lalr): Call it when --trace-flag.
20781 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
20782 are dumped.
20783
20784 2001-12-29 Akim Demaille <akim@epita.fr>
20785
20786 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
20787 when walking through ritem, even via rule->rhs.
20788 * src/reduce.c (dump_grammar, useful_production, reduce_output)
20789 (useful_production, useless_nonterminals): Likewise.
20790 (reduce_grammar_tables): Likewise, plus update nritems.
20791 * src/nullable.c (set_nullable): Likewise.
20792 * src/lalr.c (build_relations): Likewise.
20793 * tests/sets.at (Nullable): Adjust.
20794 Fortunately, now, the $axiom is no longer nullable.
20795
20796 2001-12-29 Akim Demaille <akim@epita.fr>
20797
20798 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
20799 the 0-sentinel.
20800 * src/gram.c (ritem_longest_rhs): Likewise.
20801 * src/reduce.c (nonterminals_reduce): Likewise.
20802 * src/print_graph.c (print_graph): Likewise.
20803 * src/output.c (output_rule_data): Likewise.
20804 * src/nullable.c (set_nullable): Likewise.
20805
20806 2001-12-29 Akim Demaille <akim@epita.fr>
20807
20808 * src/output.c: Comment changes.
20809
20810 2001-12-27 Paul Eggert <eggert@twinsun.com>
20811
20812 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
20813 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
20814 Sparc, as they were causing more porting problems than the
20815 (minor) performance improvement was worth.
20816
20817 Also, catch up with 1.31's YYSTD.
20818
20819 2001-12-27 Akim Demaille <akim@epita.fr>
20820
20821 * src/output.c (output_gram): Rely on nritems, not the
20822 0-sentinel. See below.
20823 Use -1 as separator, not 0.
20824 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
20825 Rely on -1 as separator in yyrhs, instead of 0.
20826 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
20827 twice `Now at end of input', therefore there are two lines less to
20828 expect.
20829
20830 2001-12-27 Akim Demaille <akim@epita.fr>
20831
20832 * tests/regression.at (Unresolved SR Conflicts):
20833 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
20834 below.
20835
20836 2001-12-27 Akim Demaille <akim@epita.fr>
20837
20838 * src/LR0.c (new_state): Recognize the final state by the fact it
20839 is reached by eoftoken.
20840 (insert_start_shifting_state, insert_eof_shifting_state)
20841 (insert_accepting_state, augment_automaton): Remove, since now
20842 these states are automatically computed from the initial state.
20843 (generate_states): Adjust.
20844 * src/print.c: When reporting a rule number to the user, substract
20845 1, so that the axiom rule is rule 0, and the first user rule is 1.
20846 * src/reduce.c: Likewise.
20847 * src/print_graph.c (print_core): For the time being, just as for
20848 the report, depend upon --trace-flags to dump the full set of
20849 items.
20850 * src/reader.c (readgram): Once the grammar read, insert the rule
20851 0: `$axiom: START-SYMBOL $'.
20852 * tests/set.at: Adjust: rule 0 is now displayed, and since the
20853 number of the states has changed (the final state is no longer
20854 necessarily the last), catch up.
20855
20856 2001-12-27 Akim Demaille <akim@epita.fr>
20857
20858 Try to make the use of the eoftoken valid. Given that its value
20859 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
20860 is used instead of > 0 where appropriate, (ii), depend upon nritems
20861 instead of the 0-sentinel.
20862
20863 * src/gram.h, src/gram.c (nritems): New.
20864 Expected to be duplication of nitems, but for the time being...
20865 * src/reader.c (packgram): Assert nritems and nitems are equal.
20866 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
20867 * src/closure.c (print_closure, print_fderives): Likewise.
20868 * src/gram.c (ritem_print): Likewise.
20869 * src/print.c (print_core, print_grammar): Likewise.
20870 * src/print_graph.c: Likewise.
20871
20872 2001-12-27 Akim Demaille <akim@epita.fr>
20873
20874 * src/main.c (main): If there are complains after grammar
20875 reductions, then output the report anyway if requested, then die.
20876 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
20877 * src/reader.c (eoftoken): New.
20878 (parse_token_decl): If the token being defined has value `0', it
20879 is the eoftoken.
20880 (packsymbols): No longer hack `tags' to insert `$' by hand.
20881 Be sure to preserve the value of the eoftoken.
20882 (reader): Make sure eoftoken is defined.
20883 Initialize nsyms to 0: now eoftoken is created just like the others.
20884 * src/print.c (print_grammar): Don't special case the eof token.
20885 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
20886 lie anyway, albeit pleasant.
20887 * tests/calc.at: Exercise error messages with eoftoken.
20888 Change the grammar so that empty input is invalid.
20889 Adjust expectations.
20890 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
20891
20892 2001-12-27 Akim Demaille <akim@epita.fr>
20893
20894 * configure.in: Check the protos of strchr ans strspn.
20895 Replace strchr if needed.
20896 * src/system.h: Provide the protos of strchr, strspn and memchr if
20897 missing.
20898 * lib/strchr.c: New.
20899 * src/reader.c (symbols_save): Use strchr.
20900
20901 2001-12-27 Akim Demaille <akim@epita.fr>
20902
20903 * src/print.c, src/print_graph.c (escape): New.
20904 Use it to quote the TAGS outputs.
20905 * src/print_graph.c (print_state): Now errors are in red, and
20906 reductions in green.
20907 Prefer high to wide: output the state number on a line of its own.
20908
20909 2001-12-27 Akim Demaille <akim@epita.fr>
20910
20911 * src/state.h, src/state.c (reductions_new): New.
20912 * src/LR0.c (set_state_table): Let all the states have a
20913 `reductions', even if reduced to 0.
20914 (save_reductions): Adjust.
20915 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
20916 * src/print.c (print_reductions, print_actions): Adjust.
20917 * src/output.c (action_row): Adjust.
20918
20919 2001-12-27 Akim Demaille <akim@epita.fr>
20920
20921 * src/state.h, src/state.c (errs_new, errs_dup): New.
20922 * src/LR0.c (set_state_table): Let all the states have an errs,
20923 even if reduced to 0.
20924 * src/print.c (print_errs, print_reductions): Adjust.
20925 * src/output.c (output_actions, action_row): Adjust.
20926 * src/conflicts.c (resolve_sr_conflict): Adjust.
20927
20928 2001-12-27 Akim Demaille <akim@epita.fr>
20929
20930 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
20931
20932 2001-12-27 Akim Demaille <akim@epita.fr>
20933
20934 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
20935 * src/print.c: here.
20936 (lookaheadset, shiftset): New, used as additional storage by
20937 print_reductions.
20938 (print_results): Adjust.
20939 (print_shifts, print_gotos, print_errs): New, extracted from...
20940 (print_actions): here.
20941 * src/print_graph.c (print_actions): Remove dead code.
20942
20943 2001-12-27 Akim Demaille <akim@epita.fr>
20944
20945 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
20946 `$n' and `@n'.
20947
20948 2001-12-27 Akim Demaille <akim@epita.fr>
20949
20950 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
20951 (build_relations): Adjust.
20952
20953 2001-12-27 Akim Demaille <akim@epita.fr>
20954
20955 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
20956 duplication.
20957
20958 2001-12-27 Akim Demaille <akim@epita.fr>
20959
20960 * src/reader.c (packgram): Catch nitems overflows.
20961
20962 2001-12-27 Akim Demaille <akim@epita.fr>
20963
20964 * src/files.c, src/files.h (guard_obstack): Remove.
20965 * src/output.c (output): Adjust.
20966 * src/reader.c (parse_braces): New, factoring...
20967 (copy_action, copy_guard): these two which are renamed as...
20968 (parse_action, parse_guard): these.
20969 As a voluntary consequence, using braces around guards is now
20970 mandatory.
20971
20972 2001-12-27 Akim Demaille <akim@epita.fr>
20973
20974 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
20975 * src/reader.c (symbol_list): `guard' and `guard_line' are new
20976 members.
20977 (symbol_list_new): Adjust.
20978 (copy_action): action_line is the first line, not the last.
20979 (copy_guard): Just as for actions, store the `action' only, not
20980 the switch/case/break flesh.
20981 Don't parse the user action that might follow the guard, let...
20982 (readgram): do it, i.e., now, there can be an action after a
20983 guard.
20984 In other words the guard is just explicitly optional.
20985 (packgram): Adjust.
20986 * src/output.c (guards_output): New.
20987 (output_parser): Call it when needed.
20988 (output): Also free the guard and attrs obstacks.
20989 * src/files.c, src/files.h (obstack_save): Remove.
20990 (output_files): Remove.
20991 As a result, if one needs the former `.act' file, using an
20992 appropriate skeleton which requires actions and guards is now
20993 required.
20994 * src/main.c (main): Adjust.
20995 * tests/semantic.at: New.
20996 * tests/regression.at: Use `input.y' as input file name.
20997 Avoid 8+3 problems by requiring input.c when the test needs the
20998 parser.
20999
21000 2001-12-27 Akim Demaille <akim@epita.fr>
21001
21002 * src/reader.c (symbol_list_new): Be sure to initialize all the
21003 fields.
21004
21005 2001-12-27 Akim Demaille <akim@epita.fr>
21006
21007 All the hacks using a final pseudo state are now useless.
21008
21009 * src/LR0.c (set_state_table): state_table holds exactly nstates.
21010 * src/lalr.c (nLA): New.
21011 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
21012 instead of lookaheadsp from the pseudo state (nstate + 1).
21013
21014 2001-12-27 Akim Demaille <akim@epita.fr>
21015
21016 * src/output.c (action_row, token_actions): Use a state_t instead
21017 of a integer, and nlookaheads instead of the following state's
21018 lookaheadsp.
21019
21020 2001-12-27 Akim Demaille <akim@epita.fr>
21021
21022 * src/conflicts.c (log_resolution, flush_shift)
21023 (resolve_sr_conflict, set_conflicts, solve_conflicts)
21024 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
21025 (conflicts_print, print_reductions): Use a state_t instead of an
21026 integer when referring to a state.
21027 As much as possible, depend upon nlookaheads, instead of the
21028 `lookaheadsp' member of the following state (since lookaheads of
21029 successive states are successive, the difference between state n + 1
21030 and n served as the number of lookaheads for state n).
21031 * src/lalr.c (add_lookback_edge): Likewise.
21032 * src/print.c (print_core, print_actions, print_state)
21033 (print_results): Likewise.
21034 * src/print_graph.c (print_core, print_actions, print_state)
21035 (print_graph): Likewise.
21036 * src/conflicts.h: Adjust.
21037
21038 2001-12-27 Akim Demaille <akim@epita.fr>
21039
21040 * src/bison.hairy: Formatting/comment changes.
21041 ANSIfy.
21042 Remove `register' indications.
21043 Add plenty of `static'.
21044
21045 2001-12-27 Akim Demaille <akim@epita.fr>
21046
21047 * src/output.c (prepare): Drop the muscle `ntbase' which
21048 duplicates ntokens.
21049 * src/bison.simple: Formatting/comment changes.
21050 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
21051 is an undocumented synonym.
21052
21053 2001-12-22 Akim Demaille <akim@epita.fr>
21054
21055 * src/output.c (output_table_data): Change the prototype to use
21056 `int' for array ranges: some invocations do pass an int, not a
21057 short.
21058 Reported by Wayne Green.
21059
21060 2001-12-22 Akim Demaille <akim@epita.fr>
21061
21062 Some actions of web2c.y are improperly triggered.
21063 Reported by Mike Castle.
21064
21065 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
21066 * tests/regression.at (Web2c): Rename as...
21067 (Web2c Report): this.
21068 (Web2c Actions): New.
21069
21070 2001-12-22 Akim Demaille <akim@epita.fr>
21071
21072 Reductions in web2c.y are improperly reported.
21073 Reported by Mike Castle.
21074
21075 * src/conflicts.c (print_reductions): Fix.
21076 * tests/regression.at (Web2c): New.
21077
21078 2001-12-18 Akim Demaille <akim@epita.fr>
21079
21080 Some host fail on `assert (!"foo")', which expands to
21081 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
21082 Reported by Nelson Beebee.
21083
21084 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
21085 `#define it_succeeded 0' and `assert (it_succeeded)'.
21086
21087 2001-12-17 Marc Autret <autret_m@epita.fr>
21088
21089 * src/bison.simple: Don't hard code the skeleton line and filename.
21090 * src/output.c (output_parser): Rename 'line' as 'output_line'.
21091 New line counter 'skeleton_line' (skeleton-line muscle).
21092
21093 2001-12-17 Paul Eggert <eggert@twinsun.com>
21094
21095 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
21096 YYDEBUG must be defined to a nonzero value.
21097
21098 * src/bison.simple (yytname): Do not assume that the user defines
21099 YYDEBUG to a properly parenthesized expression.
21100
21101 2001-12-17 Akim Demaille <akim@epita.fr>
21102
21103 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
21104 nlookaheads is a new member.
21105 Adjust all users.
21106 * src/lalr.h (nlookaheads): Remove this orphan declaration.
21107 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
21108 state.
21109
21110 2001-12-17 Akim Demaille <akim@epita.fr>
21111
21112 * src/files.h, src/files.c (open_files, close_files): Remove.
21113 * src/main.c (main): Don't open/close files, nor invoke lex_free,
21114 let...
21115 * src/reader.c (reader): Do it.
21116
21117 2001-12-17 Akim Demaille <akim@epita.fr>
21118
21119 * src/conflicts.c (print_reductions): Formatting changes.
21120
21121 2001-12-17 Akim Demaille <akim@epita.fr>
21122
21123 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
21124 (flush_reduce): New.
21125 (resolve_sr_conflict): Adjust.
21126
21127 2001-12-17 Akim Demaille <akim@epita.fr>
21128
21129 * src/output.c (output_obstack): Be static and rename as...
21130 (format_obstack): this, to avoid any confusion with files.c's
21131 output_obstack.
21132 * src/reader.h (muscle_obstack): Move to...
21133 * src/output.h: here, since it's defined in output.c.
21134
21135 2001-12-17 Akim Demaille <akim@epita.fr>
21136
21137 * src/output.c (action_row, save_column, default_goto)
21138 (sort_actions, matching_state, pack_vector): Better variable
21139 locality.
21140
21141 2001-12-17 Akim Demaille <akim@epita.fr>
21142
21143 * src/output.c: Various formatting changes.
21144
21145 2001-12-17 Akim Demaille <akim@epita.fr>
21146
21147 * src/files.c (output_files): Free the output_obstack.
21148 * src/main.c (main): Call print and print_graph conditionally.
21149 * src/print.c (print): Work unconditionally.
21150 * src/print_graph.c (print_graph): Work unconditionally.
21151 * src/conflicts.c (log_resolution): Output only if verbose_flag.
21152
21153 2001-12-16 Marc Autret <autret_m@epita.fr>
21154
21155 * src/output.c (actions_output): Fix. When we use %no-lines,
21156 there is one less line per action.
21157
21158 2001-12-16 Marc Autret <autret_m@epita.fr>
21159
21160 * src/bison.simple: Remove a useless #line directive.
21161 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
21162 * src/output.c (get_lines_number): New.
21163 (output_parser): Adjust, now takes care about the lines of a
21164 output muscles.
21165 Fix line numbering.
21166 (actions_output): Computes the number of lines taken by actions.
21167 (output_master_parser): Insert new skeleton which is the name of
21168 the output parser file name.
21169
21170 2001-12-15 Marc Autret <autret_m@epita.fr>
21171
21172 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
21173
21174 2001-12-15 Marc Autret <autret_m@epita.fr>
21175
21176 * src/output.c (output_gram): Keep track of the hairy one.
21177
21178 2001-12-15 Akim Demaille <akim@epita.fr>
21179
21180 Make `make distcheck' work.
21181
21182 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
21183 system.h which uses libgettext.h.
21184
21185 2001-12-15 Akim Demaille <akim@epita.fr>
21186
21187 * src/nullable.c (set_nullable): Useless rules must be skipped,
21188 otherwise, since we range over their symbols, we might look at a
21189 nonterminal which no longer ``exists'', i.e., it is not counted in
21190 `nvars', hence we overflow our arrays.
21191
21192 2001-12-15 Akim Demaille <akim@epita.fr>
21193
21194 The header can also be produced directly, without any obstack!
21195 Yahoo!
21196
21197 * src/files.c, src/files.h (defines_obstack): Remove.
21198 (compute_header_macro): Global.
21199 (defines_obstack_save): Remove.
21200 * src/reader.c (parse_union_decl): No longer output to
21201 defines_obstack: its content can be found in the `stype' muscle
21202 anyway.
21203 (output_token_translations): Merge into...
21204 (symbols_output): this.
21205 Rename as...
21206 (symbols_save): this.
21207 (reader): Adjust.
21208 * src/output.c (header_output): New.
21209 (output): Call it.
21210
21211 2001-12-15 Akim Demaille <akim@epita.fr>
21212
21213 * src/reader.c (parse_union_decl): Instead of handling two obstack
21214 simultaneously, use one to define the `stype' muscle, and use the
21215 value of the latter to fill defines_obstack.
21216 (copy_comment): Remove.
21217 (copy_comment2): Work for a single obstack.
21218 Rename as...
21219 (copy_comment): this.
21220
21221 2001-12-15 Akim Demaille <akim@epita.fr>
21222
21223 * src/lex.c, src/lex.h (xgetc): No longer static.
21224 * src/reader.c (parse_union_decl): Revamp.
21225
21226 2001-12-15 Akim Demaille <akim@epita.fr>
21227
21228 Still making progress in separating Bison into (i) input, (ii)
21229 process, (iii) output: now we can directly output the parser file
21230 without using table_obstack at all.
21231
21232 * src/files.c, src/files.h (table_obstack): Bye bye.
21233 (parser_file_name): New.
21234 * src/files.c (compute_output_file_names): Compute it.
21235 * src/output.c (actions_output, output_parser)
21236 (output_master_parser): To a file instead of an obstack.
21237
21238 2001-12-15 Akim Demaille <akim@epita.fr>
21239
21240 Attach actions to rules, instead of pre-outputting them to
21241 actions_obstack.
21242
21243 * src/gram.h (rule_t): action and action_line are new members.
21244 * src/reader.c (symbol_list): Likewise.
21245 (copy_action): Save the actions within the rule.
21246 (packgram): Save them in rule_table.
21247 * src/output.c (actions_output): New.
21248 (output_parser): Use it on `%%actions'.
21249 (output_rule_data): Don't free rule_table.
21250 (output): Do it.
21251 (prepare): Don't save the `action' muscle.
21252 * src/bison.simple: s/%%action/%%actions/.
21253
21254 2001-12-15 Akim Demaille <akim@epita.fr>
21255
21256 * src/reader.c (copy_action): When --yacc, don't append a `;'
21257 to the user action: let it fail if lacking.
21258 Suggested by Arnold Robbins and Tom Tromey.
21259
21260 2001-12-14 Akim Demaille <akim@epita.fr>
21261
21262 * src/lex.c (literalchar): Simply return the char you decoded, non
21263 longer mess around with obstacks and int pointers.
21264 Adjust all callers.
21265
21266 2001-12-14 Akim Demaille <akim@epita.fr>
21267
21268 * src/lex.c (literalchar): Don't escape the special characters,
21269 just decode them, and keep them as char (before, eol was output as
21270 the 2 char string `\n' etc.).
21271 * src/output.c (output_rule_data): Use quotearg to output the
21272 token strings.
21273
21274 2001-12-13 Paul Eggert <eggert@twinsun.com>
21275
21276 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
21277 Do not infringe on the global user namespace when using C++.
21278 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
21279 All uses of `fprintf' and `stderr' changed.
21280
21281 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
21282
21283 2001-12-13 Akim Demaille <akim@epita.fr>
21284
21285 The computation of nullable is broken: it doesn't handle empty
21286 RHS's properly.
21287
21288 * tests/torture.at (GNU AWK Grammar): New.
21289 * tests/sets.at (Nullable): New.
21290 * src/nullable.c (set_nullable): Instead of blindly looping over
21291 `ritems', loop over the rules, and then over their rhs's.
21292
21293 Work around Autotest bugs.
21294
21295 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
21296 frame, because Autotest understand lines starting with a `+' as
21297 traces from the shell. Then, they are not processed properly.
21298 Admittedly an Autotest bug, but we don't have time to wait for
21299 Autotest to catch up.
21300 * tests/regression.at (Broken Closure): Adjust to the new table
21301 frames.
21302 Move to...
21303 * tests/sets.at: here.
21304
21305 2001-12-13 Akim Demaille <akim@epita.fr>
21306
21307 * src/closure.c (closure): Use nrules instead of playing tricks
21308 with BITS_PER_WORD.
21309
21310 2001-12-13 Akim Demaille <akim@epita.fr>
21311
21312 * src/print.c (print_actions): Output the handling of `$' as the
21313 traces do: shifting the token EOF. Before EOF was treated as a
21314 nonterminal.
21315 * tests/regression.at: Adjust some tests.
21316 * src/print_graph.c (print_core): Complete the set of items via
21317 closure. The next-to-final and final states are still unsatisfying,
21318 but that's to be addressed elsewhere.
21319 No longer output the rule numbers, but do output the state number.
21320 A single loop for the shifts + gotos is enough, but picked a
21321 distinct color for each.
21322 (print_graph): Initialize and finalize closure.
21323
21324 2001-12-13 Akim Demaille <akim@epita.fr>
21325
21326 * src/reader.c (readgram): Remove dead code, an strip useless
21327 braces.
21328 (get_type): Remove, unused.
21329
21330 2001-12-12 Akim Demaille <akim@epita.fr>
21331
21332 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
21333 on that of lib/error.c.
21334
21335 2001-12-12 Akim Demaille <akim@epita.fr>
21336
21337 Some hosts don't like `/' in includes.
21338
21339 * src/system.h: Include libgettext.h without qualifying the path.
21340 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
21341 $(top_srcdir).
21342
21343 2001-12-11 Marc Autret <autret_m@epita.fr>
21344
21345 * src/output.c (output_parser): Remove useless muscle.
21346
21347 2001-12-11 Marc Autret <autret_m@epita.fr>
21348
21349 * src/bison.simple: Remove #line just before %%epilogue. It
21350 is now handled in ...
21351 * src/reader.c (read_additionnal_code): Add the output of a
21352 #line for the epilogue.
21353
21354 2001-12-10 Marc Autret <autret_m@epita.fr>
21355
21356 * src/reader.c (copy_definition): Re-use CPP-outed code which
21357 replace precedent remove.
21358 * src/bison.simple: Remove #line before %%prologue because
21359 %%input-line is wrong at this time.
21360
21361 2001-12-10 Marc Autret <autret_m@epita.fr>
21362
21363 * src/reader.c (symbols_output): Clean up.
21364 * src/output.c (output_gram, output): Clean up.
21365
21366 2001-12-10 Akim Demaille <akim@epita.fr>
21367
21368 * src/lalr.c (initialize_lookaheads): New. Extracted from...
21369 * src/LR0.c (set_state_table): here.
21370 * src/lalr.c (lalr): Call it.
21371
21372 2001-12-10 Akim Demaille <akim@epita.fr>
21373
21374 * src/state.h (shifts): Remove the `number' member: shifts are
21375 attached to state, hence no longer need to be labelled with a
21376 state number.
21377
21378 2001-12-10 Akim Demaille <akim@epita.fr>
21379
21380 Now that states have a complete set of members, the linked list of
21381 shifts is useless: just fill directly the state's shifts member.
21382
21383 * src/state.h (shifts): Remove the `next' member.
21384 * src/LR0.c (first_state, last_state): Remove.
21385 Adjust the callers.
21386 (augment_automaton): Don't look for the shifts that must be added
21387 a shift on EOF: it is those of the state we looked for! But now,
21388 since shifts are attached, it is no longer needed to looking
21389 merely by its id: its number.
21390
21391 2001-12-10 Akim Demaille <akim@epita.fr>
21392
21393 * src/LR0.c (augment_automaton): Better variable locality.
21394 Remove an impossible branch: if there is a state corresponding to
21395 the start symbol being shifted, then there is shift for the start
21396 symbol from the initial state.
21397
21398 2001-12-10 Akim Demaille <akim@epita.fr>
21399
21400 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
21401 only when appropriate: when insert_start_shifting_state' is not
21402 invoked.
21403 * tests/regression.at (Rule Line Numbers): Adjust.
21404
21405 2001-12-10 Akim Demaille <akim@epita.fr>
21406
21407 * src/LR0.c (augment_automaton): Now that all states have shifts,
21408 merge the two cases addition shifts to the initial state.
21409
21410 2001-12-10 Akim Demaille <akim@epita.fr>
21411
21412 * src/lalr.c (set_state_table): Move to...
21413 * src/LR0.c: here.
21414 * src/lalr.c (lalr): Don't call it...
21415 * src/LR0.c (generate_states): do it.
21416 * src/LR0.h (first_state): Remove, only the table is used.
21417
21418 2001-12-10 Akim Demaille <akim@epita.fr>
21419
21420 * src/LR0.h (first_shift, first_reduction): Remove.
21421 * src/lalr.c: Don't use first_shift: find shifts through the
21422 states.
21423
21424 2001-12-10 Akim Demaille <akim@epita.fr>
21425
21426 * src/LR0.c: Attach shifts to states as soon as they are
21427 computed.
21428 * src/lalr.c (set_state_table): Instead of assigning shifts to
21429 state, just assert that the mapping was properly done.
21430
21431 2001-12-10 Akim Demaille <akim@epita.fr>
21432
21433 * src/LR0.c (insert_start_shift): Rename as...
21434 (insert_start_shifting_state): this.
21435 (insert_eof_shifting_state, insert_accepting_state): New.
21436 (augment_automaton): Adjust.
21437 Better locality of the variables.
21438 When looking if the start_symbol is shifted from the initial
21439 state, using `while (... symbol != start_symbol ...)' sounds
21440 better than `while (... symbol < start_symbol ...)': If fail
21441 to see how the order between symbols could be relevant!
21442
21443 2001-12-10 Akim Demaille <akim@epita.fr>
21444
21445 * src/getargs.h: Don't declare `spec_name_prefix' and
21446 `spec_file_prefix', declared by src/files.h.
21447 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
21448 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
21449 * src/output.c (prepare): Adjust.
21450 * src/reader.c (symbols_output): Likewise.
21451 * src/vmsgetargs.c: Vaguely adjust, but who cares?
21452
21453 2001-12-10 Akim Demaille <akim@epita.fr>
21454
21455 * src/muscle_tab.c (muscle_init): NULL is a better default than
21456 `"0"'.
21457
21458 2001-12-10 Akim Demaille <akim@epita.fr>
21459
21460 * src/reader.c (reader): Calling symbols_output once is enough.
21461
21462 2001-12-10 Akim Demaille <akim@epita.fr>
21463
21464 Now that states have a complete set of members, the linked list of
21465 reductions is useless: just fill directly the state's reductions
21466 member.
21467
21468 * src/state.h (struct reductions): Remove member `number' and
21469 `next'.
21470 * src/LR0.c (first_reduction, last_reduction): Remove.
21471 (save_reductions): Don't link the new reductions, store them in
21472 this_state.
21473 * src/lalr.c (set_state_table): No need to attach reductions to
21474 states, it's already done.
21475 * src/output.c (output_actions): No longer free the shifts, then
21476 the reductions, then the states: free all the states and their
21477 members.
21478
21479 2001-12-10 Akim Demaille <akim@epita.fr>
21480
21481 * src/options.c (OPTN, DRTV, BOTH): New.
21482 (option_table): Use them.
21483
21484 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
21485 the job of system.h.
21486 * src/options.c: Don't include stdio.h and xalloc.h for the same
21487 reasons.
21488
21489 2001-12-10 Akim Demaille <akim@epita.fr>
21490
21491 * src/output.c (output, prepare): Make sure the values of the
21492 muscles `action' and `prologue' are 0-terminated.
21493
21494 2001-12-10 Akim Demaille <akim@epita.fr>
21495
21496 Clean up GCC warnings.
21497
21498 * src/reader.c (copy_action): `buf' is not used.
21499 (parse_skel_decl): Be static.
21500 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
21501 * src/options.h (create_long_option_table): Have a real prototype.
21502 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
21503 (hash_delete_at): Return const void *.
21504 Adjust casts to preserve the const.
21505
21506 2001-12-10 Akim Demaille <akim@epita.fr>
21507
21508 * configure.in: Require 2.52g.
21509 M4 is not needed, but AUTOM4TE is.
21510 * m4/m4.m4: Remove.
21511 * tests/Makefile.am: Adjust.
21512
21513 2001-12-10 Akim Demaille <akim@epita.fr>
21514
21515 One structure for states is enough, even though theoretically
21516 there are LR(0) states and LALR(1) states.
21517
21518 * src/lalr.h (state_t): Remove.
21519 (state_table): Be state_t **, not state_t *.
21520 * src/state.h (core, CORE_ALLOC): Rename as...
21521 (state_t, STATE_ALLOC): this.
21522 Add the LALR(1) members: shifts, reductions, errs.
21523 * src/LR0.c (state_table): Rename as...
21524 (state_hash): this, to avoid name clashes with the global
21525 `state_table'.
21526 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
21527 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
21528
21529 2001-12-10 Akim Demaille <akim@epita.fr>
21530
21531 Bison dumps core on bash.y.
21532 Reported by Pascal Bart.
21533
21534 * src/warshall.c (bitmatrix_print): New.
21535 (TC): Use it.
21536 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
21537 j must be the outer loop.
21538 * tests/regression.at (Broken Closure): New.
21539
21540 2001-12-05 Akim Demaille <akim@epita.fr>
21541
21542 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
21543 its argument.
21544 Reported by Peter Hamorsky.
21545
21546 2001-12-05 Akim Demaille <akim@epita.fr>
21547
21548 * src/conflicts.c (err_table): Remove.
21549 (resolve_sr_conflict): Adjust.
21550 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
21551 Rename as...
21552 (state_t.reductions, state_t.shifts): this.
21553
21554 2001-12-05 Akim Demaille <akim@epita.fr>
21555
21556 * src/reduce.c (reduce_grammar_tables): No longer disable the
21557 removal of useless rules via CPP but via `if (0)', so that the
21558 compiler still check the code is valid.
21559 For instance, it should have noticed `rline' no longer exists: use
21560 the `line' member of rule_t.
21561 * src/gram.c (dummy, rline): Remove, unused.
21562
21563 2001-12-05 Akim Demaille <akim@epita.fr>
21564
21565 * src/output.c (pack_vector): Use assert, not berror.
21566 * src/main.c (berror): Remove, unused.
21567
21568 2001-12-05 Akim Demaille <akim@epita.fr>
21569
21570 New experimental feature: if --verbose --trace output all the
21571 items of a state, not only its kernel.
21572
21573 * src/print.c (print_core): If `trace_flag', then invoke closure
21574 before outputting the items of the state (print_core is no longer
21575 a correct name them).
21576 (print_results): Invoke new_closure/free_closure if needed.
21577
21578 2001-12-05 Akim Demaille <akim@epita.fr>
21579
21580 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
21581 * src/closure.c, src/closure.h (itemsetsize): Rename as...
21582 (nitemset): for consistency with the rest of the project.
21583
21584 2001-12-05 Akim Demaille <akim@epita.fr>
21585
21586 * src/closure.c (print_closure): Improve.
21587 (closure): Use it for printing input and output.
21588
21589 2001-12-05 Akim Demaille <akim@epita.fr>
21590
21591 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
21592 indexed by nonterminals.
21593
21594 2001-12-05 Akim Demaille <akim@epita.fr>
21595
21596 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
21597 what it was!).
21598 * src/warshall.h: Remove accidental duplication of the content.
21599
21600 2001-12-05 Akim Demaille <akim@epita.fr>
21601
21602 * src/closure.c (set_fderives): De-obfuscate.
21603
21604 2001-12-05 Akim Demaille <akim@epita.fr>
21605
21606 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
21607
21608 2001-12-05 Akim Demaille <akim@epita.fr>
21609
21610 * src/closure.c (set_firsts): De-obfuscate.
21611
21612 2001-12-05 Akim Demaille <akim@epita.fr>
21613
21614 * src/output.c (action_row): De-obfuscate
21615 using the good o' techniques: arrays not pointers, variable
21616 locality, BITISSET, RESETBIT etc.
21617
21618 2001-12-05 Akim Demaille <akim@epita.fr>
21619
21620 Pessimize the code to simplify it: from now on, all the states
21621 have a valid SHIFTS, which NSHIFTS is possibly 0.
21622
21623 * src/LR0.c (shifts_new): Be global and move to..
21624 * src/state.c, src/state.h: here.
21625 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
21626 * src/print_graph: Adjust.
21627
21628 2001-12-05 Akim Demaille <akim@epita.fr>
21629
21630 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
21631 * src/conflicts.c: Use it.
21632 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
21633 incorrectly ``simplified''.
21634
21635 2001-12-05 Akim Demaille <akim@epita.fr>
21636
21637 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
21638 using the good o' techniques: arrays not pointers, variable
21639 locality, BITISSET, RESETBIT etc.
21640
21641 2001-12-05 Akim Demaille <akim@epita.fr>
21642
21643 * src/state.h (SHIFT_SYMBOL): New.
21644 * src/conflicts.c: Use it to deobfuscate.
21645
21646 2001-12-05 Akim Demaille <akim@epita.fr>
21647
21648 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
21649 (print_reductions): De-obfuscate using the good o' techniques:
21650 arrays not pointers, variable locality, BITISSET.
21651
21652 2001-12-05 Akim Demaille <akim@epita.fr>
21653
21654 * src/conflicts.c (print_reductions): Arrays, not pointers.
21655 Use BITISSET.
21656
21657 2001-12-05 Akim Demaille <akim@epita.fr>
21658
21659 * src/conflicts.c (print_reductions): Pessimize, but clarify.
21660
21661 2001-12-05 Akim Demaille <akim@epita.fr>
21662
21663 * src/conflicts.c (print_reductions): Improve variable locality.
21664
21665 2001-12-05 Akim Demaille <akim@epita.fr>
21666
21667 * src/conflicts.c (print_reductions): Pessimize, but clarify.
21668
21669 2001-12-05 Akim Demaille <akim@epita.fr>
21670
21671 * src/conflicts.c (print_reductions): Improve variable locality.
21672
21673 2001-12-05 Akim Demaille <akim@epita.fr>
21674
21675 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
21676 * src/lalr.c: Use them.
21677
21678 2001-12-05 Akim Demaille <akim@epita.fr>
21679
21680 * src/LR0.c (augment_automaton): Formatting changes.
21681 Better variable locality.
21682
21683 2001-12-05 Akim Demaille <akim@epita.fr>
21684
21685 * src/lalr.c (matrix_print): New.
21686 (transpose): Use it.
21687 Use arrays instead of pointers.
21688
21689 2001-12-05 Akim Demaille <akim@epita.fr>
21690
21691 * src/lalr.c (maxrhs): Move to...
21692 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
21693 * src/lalr.c (build_relations): Adjust.
21694
21695 2001-12-05 Akim Demaille <akim@epita.fr>
21696
21697 * src/lalr.c (transpose): Free the memory allocated to the
21698 argument, as it is replaced by the results by the unique caller.
21699 (build_relations): Merely invoke transpose: it handles the memory
21700 deallocation.
21701 Improve variable locality.
21702 Avoid variables used as mere abbreviations.
21703 (compute_lookaheads): Use arrays instead of pointers.
21704
21705 2001-12-05 Akim Demaille <akim@epita.fr>
21706
21707 * src/lalr.c (initialize_F): Improve variable locality.
21708 Avoid variables used as mere abbreviations.
21709
21710 2001-12-05 Akim Demaille <akim@epita.fr>
21711
21712 * src/derives.c (print_derives): Display the ruleno.
21713 * src/lalr.c (initialize_F, transpose): Better variable locality
21714 to improve readability.
21715 Avoid variables used as mere abbreviations.
21716
21717 2001-12-05 Akim Demaille <akim@epita.fr>
21718
21719 * src/lalr.c (traverse): Use arrays instead of pointers.
21720
21721 2001-12-05 Akim Demaille <akim@epita.fr>
21722
21723 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
21724 the handling of squeue.
21725 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
21726
21727 2001-12-05 Akim Demaille <akim@epita.fr>
21728
21729 Because useless nonterminals are now kept alive (instead of being
21730 `destroyed'), we now sometimes examine them, and store information
21731 related to them. Hence we need to know their number, and adjust
21732 memory allocations.
21733
21734 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
21735 static.
21736 * src/LR0.c (allocate_itemsets): The memory allocated to
21737 `symbol_count' was used for two different purpose: once to count
21738 the number of occurrences of each symbol, and later reassigned to
21739 `shift_symbol', containing the symbol that can be shifted from a
21740 given state.
21741 Deobfuscate, i.e., allocate, use and free `symbol_count' here
21742 only, and...
21743 (new_itemsets): Allocate `shift_symbol' here.
21744 (allocate_itemsets): symbol_count includes useless nonterminals.
21745 Make room for them.
21746 (free_storage): Use `free', not `XFREE', for pointers that cannot
21747 be null.
21748
21749 2001-12-05 Akim Demaille <akim@epita.fr>
21750
21751 * src/nullable.c (set_nullable): Deobfuscate the handling of
21752 ritem.
21753 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
21754
21755 2001-12-05 Akim Demaille <akim@epita.fr>
21756
21757 * src/gram.c, src/gram.h (ritem_print): New.
21758 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
21759 (This useless function was defined only to work around VMS linkers
21760 that can't handle compilation units with variables only).
21761 * src/reduce.c (dump_grammar): Use it to trace the construction of
21762 ritem.
21763
21764 2001-12-04 Paul Eggert <eggert@twinsun.com>
21765
21766 * src/bison.simple (union yyalloc): Change member names
21767 to be the same as the stack names.
21768 (yyparse): yyptr is now union yyalloc *, not char *.
21769 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
21770 and may generate better code on some machines.
21771 (yystpcpy): Use prototype if __STDC__ is defined, not just
21772 if __cplusplus is defined.
21773
21774 2001-11-30 Akim Demaille <akim@epita.fr>
21775
21776 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
21777 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
21778 Gettext doesn't compile cleanly, and dies with -Werror.
21779 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
21780 Include WARNING_CFLAGS here.
21781 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
21782 before being defined.
21783
21784 2001-11-27 Paul Eggert <eggert@twinsun.com>
21785
21786 * lib/quotearg.h (quotearg_n, quotearg_n_style):
21787 First arg is int, not unsigned.
21788 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
21789 (SIZE_MAX, UINT_MAX): New macros.
21790 (quotearg_n_options): Abort if N is negative.
21791 Avoid overflow check on hosts where size_t is 64 bits and int
21792 is 32 bits, as overflow is impossible there.
21793 Fix off-by-one typo that caused unnecessary reallocation.
21794
21795 2001-11-29 Paul Eggert <eggert@twinsun.com>
21796
21797 Name space cleanup in generated parser.
21798
21799 * doc/bison.texinfo (Bison Parser): Discuss system headers
21800 and their effect on the user name space.
21801
21802 * src/bison.simple:
21803 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
21804 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
21805 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
21806
21807 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
21808 on user names when possible.
21809
21810 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
21811 Simplify test for whather <alloca.h> exists.
21812
21813 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
21814
21815 (<stdio.h>): Include if YYDEBUG.
21816
21817 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
21818 ! defined (yyoverflow) && ! defined (yymemcpy).
21819
21820 (yymemcpy, yyparse): Rename local variables as needed so that
21821 they all begin with 'yy'.
21822
21823 (yystrlen, yystpcpy): New functions.
21824
21825 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
21826 All uses changed.
21827
21828 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
21829 instead of relying on string.h functions. Use YYSTACK_ALLOC
21830 and YYSTACK_FREE instead of malloc and free.
21831
21832 2001-11-30 Akim Demaille <akim@epita.fr>
21833
21834 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
21835 before their first uses.
21836 (YYBISON, YYPURE): Move to the top of the output.
21837
21838 2001-11-30 Akim Demaille <akim@epita.fr>
21839
21840 * tests/reduce.at (Useless Nonterminals): Fix.
21841
21842 2001-11-30 Akim Demaille <akim@epita.fr>
21843
21844 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
21845 if body instead of `;' to pacify GCC's warnings.
21846
21847 2001-11-30 Akim Demaille <akim@epita.fr>
21848
21849 Instead of mapping the LHS of unused rules to -1, keep the LHS
21850 valid, but flag the rules as invalid.
21851
21852 * src/gram.h (rule_t): `useful' is a new member.
21853 * src/print.c (print_grammar): Adjust.
21854 * src/derives.c (set_derives): Likewise.
21855 * src/reader.c (packgram, reduce_output): Likewise.
21856 * src/reduce.c (reduce_grammar_tables): Likewise.
21857 * tests/reduce.at (Underivable Rules, Useless Rules): New.
21858
21859 2001-11-30 Akim Demaille <akim@epita.fr>
21860
21861 * src/reduce.c (reduce_output): Formatting changes.
21862 * src/print.c (print_results, print_grammar): Likewise.
21863 * tests/regression.at (Rule Line Numbers)
21864 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
21865
21866 2001-11-30 Akim Demaille <akim@epita.fr>
21867
21868 * src/reduce.c (nonterminals_reduce): Instead of throwing away
21869 useless nonterminals, move them at the end of the symbol arrays.
21870 (reduce_output): Adjust.
21871 * tests/reduce.at (Useless Nonterminals): Adjust.
21872
21873 2001-11-30 Akim Demaille <akim@epita.fr>
21874
21875 * src/reduce.c: Various comment/formatting changes.
21876 (nonterminals_reduce): New, extracted from...
21877 (reduce_grammar_tables): here.
21878 (reduce_grammar): Call nonterminals_reduce.
21879
21880 2001-11-29 Paul Eggert <eggert@twinsun.com>
21881
21882 * src/bison.simple (YYSTACK_REALLOC): Remove.
21883 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
21884 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
21885 New macros.
21886 (union yyalloc): New type.
21887 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
21888 an arbitrary restriction on hosts where size_t is wider than int.
21889
21890 (yyparse): Don't dump core if alloca or malloc fails; instead, report
21891 a parser stack overflow. Allocate just one block of memory for all
21892 three stacks, instead of allocating three blocks; this typically is
21893 faster and reduces fragmentation.
21894
21895 Do not limit the number of items in the stack to a value that fits
21896 in 'int', as this is an arbitrary limit on hosts with 64-bit
21897 size_t and 32-bit int.
21898
21899 2001-11-29 Marc Autret <autret_m@epita.fr>
21900
21901 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
21902 of defining YYERROR_VERBOSE.
21903 [AT_DATA]: $4 is now out of C declarations in the prologue.
21904
21905 2001-11-28 Marc Autret <autret_m@epita.fr>
21906
21907 * src/reader.c (parse_dquoted_param): New.
21908 (parse_skel_decl): Use it.
21909 * src/lex.h: Add its prototype.
21910 * src/lex.c (literalchar): Become not static.
21911
21912 2001-11-28 Marc Autret <autret_m@epita.fr>
21913
21914 * src/output.h: And put its extern declaration here.
21915 * src/output.c (error_verbose): Define here.
21916 (prepare): Echo name modification.
21917 * src/getargs.h: Clean its extern declaration.

23665
23666 2001-07-14 Akim Demaille <akim@epita.fr>

23671
23672 2001-03-16 Akim Demaille <akim@epita.fr>
23673
23674 * doc/bison.texinfo: ANSIfy the examples.

23676 2001-03-16 Akim Demaille <akim@epita.fr>
23677
23678 * getargs.c (skeleton): New variable.

23692 * src/getargs.c (longopts): Clean up.
23693
23694 2001-02-21 Akim Demaille <akim@epita.fr>
23695
23696 * src/reader.c (gensym): `gensym_count' is your own.
23697 Use a static buf to create the symbol name, as token_buffer is no
23698 longer a buffer.

23701
23702 * src/conflicts.c (conflict_report): Be sure not to append to res
23703 between two calls, which could happen if both first sprintf were

23707
23708 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
23709 New, from fileutils 4.0.37.
23710 * configure.in: Require Autoconf 2.49c. I took some time before
23711 making this decision. This is the only way out for portability
23712 issues in Bison, it would mean way too much duplicate effort to
23713 import in Bison features implemented in 2.49c since 2.13.
23714 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
23715

23727 (init_lex): Initialize it. No longer call...

23730
23731 2001-01-19 Akim Demaille <akim@epita.fr>
23732
23733 * src/lex.h: Rename all the tokens:
23734 s/\bENDFILE\b/tok_eof/g;
23735 s/\bIDENTIFIER\b/tok_identifier/g;
23736 etc.
23737 Let them be enums, not #define, to ease debugging.
23738 Adjust all the code.
23739
23740 2001-01-18 Akim Demaille <akim@epita.fr>
23741

23744
23745 2001-01-18 Akim Demaille <akim@epita.fr>
23746
23747 Since we now use obstacks, more % directives can be enabled.
23748
23749 * src/lex.c (percent_table): Also accept `%yacc',
23750 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
23751 `%debug'.
23752 Handle the actions for `%semantic_parser' and `%pure_parser' here,
23753 instead of returning a token.
23754 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
23755 * src/reader.c (read_declarations): Adjust.
23756 * src/files.c (open_files): Don't call `compute_base_names', don't
23757 compute `attrsfile' since they depend upon data which might be
23758 *in* the input file now.
23759 (output_files): Do it here.
23760 * src/output.c (output_headers): Document the fact that this patch
23761 introduces a guaranteed SEGV for semantic parsers.
23762 * doc/bison.texinfo: Document them.
23763 * tests/suite.at: Exercise these %options.
23764

23783
23784 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

23786 FILE * parameters.
23787
23788 2000-12-20 Akim Demaille <akim@epita.fr>
23789
23790 * src/files.c (open_files): Actually the `.output' file is based
23791 on the short_base_name, not base_name.
23792 * tests/suite.at (Checking output file names): Adjust.
23793
23794 2000-12-20 Akim Demaille <akim@epita.fr>

23817 2000-12-19 Akim Demaille <akim@epita.fr>

23819 * src/files.c (strsuffix): New.
23820 (stringappend): Be just like strcat but allocate.
23821 (base_names): Eve out from open_files.
23822 Try to simplify the rather hairy computation of base_name and
23823 short_base_name.
23824 (open_files): Use it.
23825 * tests/suite.at (Checking output file names): New test.
23826
23827 2000-12-19 Akim Demaille <akim@epita.fr>

23843 2000-12-19 Akim Demaille <akim@epita.fr>
23844
23845 Let the handling of the skeleton files be local to the procedures

23863 2000-12-19 Akim Demaille <akim@epita.fr>
23864
23865 * src/files.c (open_files): Yipee! We no longer need all the code
23866 looking for `/tmp' since we have no tmp file.
23867
23868 2000-12-19 Akim Demaille <akim@epita.fr>
23869

23899 prevents type checking.
23900 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
23901 cast the value to (void *): assigning a `foo *' to a `void *'

23904 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

23948 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
23949 argument `data' for consistency with the prototypes.
23950 Qualify it `const'.
23951 (obstack_copy, obstack_copy0): Rename the second argument as

24089
24090 2000-10-04 Akim Demaille <akim@epita.fr>
24091
24092 When a literal string is used to define two different tokens,
24093 `bison -v' segfaults.
24094 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
24095
24096 * tests/regression.m4: New file.
24097 Include the core of the sample provided by Piotr Gackiewicz.
24098 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
24099 properly.
24100
24101 2000-10-04 Akim Demaille <akim@epita.fr>
24102
24103 * src/reader.c (parse_expect_decl): Keep `count' within the size
24104 of `buffer'.
24105 From Neil Booth.
24106
24107 2000-10-02 Paul Eggert <eggert@twinsun.com>
24108
24109 * bison.s1 (yyparse): Assign the default value
24110 unconditionally, to avoid a GCC warning and make the parser a
24111 tad smaller.
24112
24113 2000-10-02 Akim Demaille <akim@epita.fr>
24114
24115 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
24116 options.
24117
24118 2000-10-02 Akim Demaille <akim@epita.fr>
24119
24120 * src/derives.c, src/print.c, src/reduce.c: To ease the
24121 translation, move some `\n' out of the translated strings.
24122
24123 2000-10-02 Akim Demaille <akim@epita.fr>
24124
24125 The location tracking mechanism is precious for parse error
24126 messages. Nevertheless, it is enabled only when `@n' is used in
24127 the grammar, which is a different issue (you can use it in error
24128 message, but not in the grammar per se). Therefore, there should
24129 be another means to enable it.
24130
24131 * src/getargs.c (getargs): Support `--locations'.
24132 (usage): Report it.
24133 * src/getargs.h (locationsflag): Export it.
24134 * src/lex.c (percent_table): Support `%locations'.
24135 * src/reader.c (yylsp_needed): Remove this variable, now replaced
24136 with `locationsflag'.
24137 * doc/bison.texinfo: Document `--locations' and `%locations'.
24138 Sort the options.
24139 * tests/calc.m4: Test it.
24140
24141 For regularity of the names, replace each
24142 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
24143 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
24144 In addition replace each `flag' with `_flag'.
24145
24146 2000-10-02 Akim Demaille <akim@epita.fr>
24147
24148 Also test parse error messages, including with YYERROR_VERBOSE.
24149
24150 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
24151 associative).
24152 Use it to check the computations.
24153 Use it to check `nonassoc' is honored.
24154 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
24155 `--yyerror-verbose'.
24156 (_AT_CHECK_CALC): Adjust to this option.
24157 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
24158
24159 2000-10-02 Akim Demaille <akim@epita.fr>
24160
24161 Test also `--verbose', `--defines' and `--name-prefix'. Testing
24162 the latter demonstrates a flaw in the handling of non debugging
24163 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
24164 was used in order to simplify:
24165
24166 #if YYDEBUG
24167 if (yydebug)
24168 {
24169 ...
24170 }
24171 #endif
24172
24173 into
24174
24175 if (yydebug)
24176 {
24177 ...
24178 }
24179
24180 unfortunately this leads to a CPP conflict when
24181 `--name-prefix=foo' is used since it produces `#define yydebug
24182 foodebug'.
24183
24184 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
24185 (YYDPRINTF): New macro.
24186 Spread its use.
24187 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
24188 the bison options.
24189 Also test `--verbose', `--defines' and `--name-prefix'.
24190
24191 2000-10-02 Akim Demaille <akim@epita.fr>
24192
24193 Improve the readability of the produced parsers.
24194
24195 * src/bison.s1: Formatting changes.
24196 Improve the comment related to the `$' mark.
24197 (yydefault): Don't fall through to `yyresume': `goto' there.
24198 * src/output.c (output_parser): When the `$' is met, skip the end
24199 of its line.
24200 New variable, `number_of_dollar_signs', to check there's exactly
24201 one `$' in the parser skeleton.
24202
24203 2000-10-02 Akim Demaille <akim@epita.fr>
24204
24205 * lib/xstrdup.c: New file, from the fileutils.
24206 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
24207 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
24208 instead of strlen + xmalloc + strcpy.
24209 * src/symtab.c (copys): Remove, use xstrdup instead.
24210
24211 2000-10-02 Akim Demaille <akim@epita.fr>
24212
24213 * src/gram.h (associativity): New enum type which replaces the
24214 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
24215 `right_assoc', `left_assoc' and `non_assoc'.
24216 Adjust all dependencies.
24217 * src/reader.c: Formatting changes.
24218 (LTYPESTR): Don't define it, use it as a literal in
24219 `reader_output_yylsp'.
24220 * src/symtab.h (symbol_class): New enum type which replaces the
24221 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
24222 `sunknown', `stoken and `snterm'.
24223
24224 2000-10-02 Akim Demaille <akim@epita.fr>
24225
24226 * src/getargs.c (fixed_outfiles): Rename as...
24227 (yaccflag): for consistency and accuracy.
24228 Adjust dependencies.
24229
24230 2000-10-02 Akim Demaille <akim@epita.fr>
24231
24232 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
24233 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
24234 difficult and introduced a lot of core dump. It turns out that
24235 Bison used an implementation of `xmalloc' based on `calloc', and
24236 at various places it does depend upon the initialization to 0. I
24237 have not tried to isolate the pertinent places, and all the former
24238 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
24239 someone should address this issue.
24240
24241 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
24242 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

24287 Propagate its inclusion.
24288
24289 2000-10-02 Akim Demaille <akim@epita.fr>

24338 output_short_table.
24339
24340 2000-10-02 Akim Demaille <akim@epita.fr>
24341
24342 `user_toknums' is output as a `short[]' in `output.c', while it is
24343 defined as a `int[]' in `reader.c'. For consistency with the
24344 other output tables, `user_toknums' is now defined as a table of
24345 shorts.
24346
24347 * src/reader.c (user_toknums): Be a short table instead of an int
24348 table.

24386 inclusion.
24387 Don't define PARAMS.
24388 * src/system.h: Define PARAMS.

24391 definitions in config.h.
24392
24393 2000-09-20 Akim Demaille <akim@epita.fr>

24609 Change the handling of @s so that they behave exactly like $s.
24610 There is now a pseudo variable @$ (readble and writable), location
24611 of the lhs of the rule (by default ranging from the location of
24612 the first symbol of the rhs, to the location of the last symbol,

24648 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

25376 way to specify the flags -n, -l, and -r. Also added hooks for
