259 * tests/c++.at (AT_CHECK_VARIANTS): In list.yy, redefine the
260 pretty-printing of lists into something better for parser traces.
261 Update the expected output.
262 Fix correspondance between %type/%token and %printer.

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.

473 portability: fix several issues with M4 subprocess.
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>.
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.
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.

586 Fix some comments concerning LR(0) versus LALR(1).
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.

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
666 * NEWS (2.5): Document.
667 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
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.

1023 an "invalid reference" is detected in named references
1025 * src/scan-code.l: Update "invalid reference" case.
1026 * tests/named-ref.at: Adjust test-cases.
1028 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
1030 Clean up yacc.c a little.
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.
1036 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
1038 Fix --enable-gcc-warnings.
1039 * src/parse-gram.y (%printer <param>): Handle param_none.
1041 2009-09-09 Akim Demaille <demaille@gostai.com>
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.
1050 * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
1051 Declare and define yy::parser::syntax_error.

1104 Adjust the grammar to use it.
1105 * src/scan-gram.l (RETURN_VALUE): New.
1106 (RETURN_PERCENT_FLAG): Use it.
1107 (RETURN_PERCENT_PARAM): New.
1108 Use it to support %parse-param, %lex-param and %param.
1110 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
1112 Use aver not assert.
1113 * src/output.c: Don't include assert.h.
1114 (output_skeleton): Use aver not assert.
1115 * src/system.h (aver): In documentation of why, add links to
1116 Paul Eggert's explanations in the mailing lists.
1118 2009-09-05 Alex Rozenman <rozenman@gmail.com>
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.
1127 2009-09-04 Akim Demaille <demaille@gostai.com>
1129 Adjust synclines in src/parse-gram.[ch].
1130 * tests/bison.in: Do some magic (including working around issues
1131 with ylwrap) when this wrapper is used to compile
1134 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
1136 Complain about unused %define variables and %code qualifiers.
1137 * NEWS (2.5): Document.
1138 * data/bison.m4 (b4_check_user_names): Complain instead of warn.
1139 * doc/bison.texinfo (Decl Summary): Document complaint, and
1140 improve %define documentation a little otherwise.
1141 * tests/input.at (Reject unused %code qualifiers): Update.
1142 (%define errors): Update.
1143 (%define, --define, --force-define): Update.

1146 * tests/push.at (Push Parsing: Unsupported Skeletons): Update.
1148 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
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.
1155 2009-09-03 Akim Demaille <demaille@gostai.com>
1157 * NEWS (2.4.2): Add "Internationalization" item.
1159 2009-09-03 Akim Demaille <demaille@gostai.com>

1163 Fix typo about find_tool_names.
1165 2009-08-29 Joel E. Denny <jdenny@clemson.edu>
1167 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
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
1175 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
1177 %define: accept unquoted values.
1178 * NEWS (2.5): Group all %define changes together, and document
1179 this one. Remove quotes in IELR and canonical LR entry.
1180 * doc/bison.texinfo: Remove quotes in most examples throughout.
1181 (Decl Summary): Update %define documentation.
1182 (Table of Symbols): Likewise.
1183 * src/ielr.c (LrType): Update documentation.

1207 * tests/reduce.at (AT_TEST_LR_TYPE): Likewise.
1209 2009-08-27 Eric Blake <ebb9@byu.net>
1211 scan-gram: avoid portability trap with ctype usage.
1212 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
1213 Avoid compiler warning.
1215 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
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
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.
1225 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
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.
1231 2009-08-26 Akim Demaille <demaille@gostai.com>
1233 tests: portability fix.
1234 * tests/input.at (Bad escapes in literals): Don't expect "echo
1235 '\0'" to output \ then 0.
1237 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
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
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.
1251 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
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
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
1274 (yyrecoverSyntaxError): Update for renames. No behavioral
1276 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
1278 (yy_table_value_is_error_): New function.
1279 (parse): Use new functions where possible. No behavioral
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.
1295 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1297 Fix %error-verbose for conflicts resolved by %nonassoc.
1298 * NEWS (2.5): Document.

1310 Some code and documentation improvements.
1311 * data/c.m4 (b4_table_value_equals): New macro to capture

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.
1324 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
1326 Use locale when quoting.
1327 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
1328 quote rather than implementing quoting here.
1330 2009-08-20 Eric Blake <ebb9@byu.net>
1332 Make previous patch more robust.
1333 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
1335 (output_skeleton): Use it.
1336 Suggested by Akim Demaille.
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.
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
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.
1364 2009-08-19 Akim Demaille <demaille@gostai.com>
1367 * doc/bison.texinfo: Fix minor Texinfo errors.
1369 2009-08-19 Akim Demaille <demaille@gostai.com>
1371 tests: distcc compliance.
1372 * tests/synclines.at (AT_SYNCLINES_COMPILE): Discard distcc's
1373 error messages from the output.
1375 2009-08-19 Akim Demaille <demaille@gostai.com>
1377 variables: simplify the upgrade of namespace into api.namespace.
1379 This patch simplifies "variables: rename namespace as
1380 api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
1381 Suggested by Joel E. Denny in
1382 http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
1384 * src/muscle-tab.c (muscle_percent_variable_update): New.
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):
1390 * data/c++.m4: No longer handle namespace -> api.namespace.
1391 * tests/input.at (%define backward compatibility): Check that
1392 namespace is treated as api.namespace.
1394 2009-08-19 Akim Demaille <demaille@gostai.com>
1396 doc: %initial-action to initialize yylloc.

1406 Move argument names into yy*.
1408 2009-08-19 Akim Demaille <demaille@gostai.com>
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
1416 * data/glr.c (yyLRgotoState): Fuse variable definition and first
1418 * data/lalr1.cc (yy_lr_goto_state_): New.
1420 Replace remaining uses of yystate by yystate_[0].state.
1423 2009-08-19 Akim Demaille <demaille@gostai.com>
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.
1432 2009-08-18 Joel E. Denny <jdenny@clemson.edu>

1443 build: require gettext 0.17.
1445 Suggested by Bruno Haible.
1446 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
1447 * configure.ac: require gettext 0.17 to ensure compatibility with
1450 2009-08-17 Akim Demaille <demaille@gostai.com>
1452 build: lower gettext requirements.
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
1459 * configure.ac: Require need-ngettext instead of
1460 need-formatstring-macros.

1477 Make it easier to write deterministic tests.
1478 Continues Akim's work from his 2009-06-10 commits.
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.
1483 (symbol_from_uniqstr): If a new symbol is being created, assert
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

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.
1509 This might also be a more convincing explanation for the failure
1510 described in the patch "build: fix paths".
1512 * Makefile.am (SUFFIXES): Initialize.
1513 * build-aux/move-if-change: New, symlink to gnulib's.

1518 ($(CROSS_OPTIONS_TEXI)): Depend on it.
1520 (.x.1): Replace with...
1521 (doc/bison.1): this explicit, simpler, target.
1522 (common_dep): Remove, inlined where appropriate.
1523 (SUFFIXES, PREPATH): Remove, unused.
1525 2009-08-12 Akim Demaille <demaille@gostai.com>
1527 gnulib: improve prefixing.

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,
1548 ranlib lib/libbison.a
1549 ranlib lib/libbison.a
1550 make[2]: *** [lib/libbison.a] Segmentation fault

1565 * tests/local.mk (TESTSUITE_AT): Add named-refs.at.
1567 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
1569 Miscellaneous code readability improvements.
1571 * src/reader.c (reader): Move %define front-end variable
1572 defaults and checking into...
1573 (prepare_percent_define_front_end_variables): ... this new
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
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
1593 (symbol_make_alias): Improve comments and argument name.
1594 * src/output.c (token_definitions_output): Update for rename to

1606 maint: run "make update-copyright"
1608 2009-08-06 Joel E. Denny <jdenny@clemson.edu>
1610 maint: make update-b4-copyright easier to use
1611 * build-aux/update-b4-copyright: In warnings, report line
1612 numbers rather than character positions.
1613 * cfg.mk (update-copyright-local): Set to update-b4-copyright so
1614 that update-copyright runs it.
1617 2009-08-05 Joel E. Denny <jdenny@clemson.edu>
1619 maint: clean up update-b4-copyright code
1620 * build-aux/update-b4-copyright: Do not accept 2-digit
1621 UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
1622 Don't accept a `[' in a b4_copyright argument.
1623 Format code more consistently.
1624 Don't assume b4*copyright never occurs.
1626 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
1628 maint: automate b4_copyright updates.
1629 * Makefile.am (update-b4-copyright): New target rule.
1630 * build-aux/local.mk (EXTRA_DIST): Add update-b4-copyright.
1631 * build-aux/update-b4-copyright: New.
1632 * data/yacc.c: Remove stray characters around b4_copyright
1635 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
1637 maint: automate annual package-wide copyright-year update.
1638 * .x-update-copyright: New.
1639 * Makefile.am (EXTRA_DIST): Remove maint.mk.
1640 * bootstrap.conf (gnulib_modules): Add maintainer-makefile and
1641 update-copyright. Remove gnumakefile, which is implied by
1642 maintainer-makefile.
1643 * cfg.mk (bootstrap-tools): Copy from old maint.mk.
1645 * maint.mk: Remove, now copied from gnulib.
1646 * examples/extexi: Add missing "(C)" in copyright statement so
1647 update-copyright can recognize it.
1648 * src/LR0.h: Likewise.
1649 * src/print.h: Likewise.
1650 * src/print_graph.h: Likewise.

1660 2009-08-01 Joel E. Denny <jdenny@clemson.edu>
1662 Pacify "gcc -Wunused" for the input function from Flex.
1663 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
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.
1671 * src/scan-gram.l: Likewise.
1672 * src/scan-skel.l: Likewise.
1674 2009-07-31 Alex Rozenman <rozenman@gmail.com>
1676 Fix --enable-gcc-warnings problems.
1677 * src/reader.c: Adjust variable names.
1678 * src/scan-code.l: Fix prototypes and adjust names.

1681 2009-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
1683 Fix a --enable-gcc-warnings problem.
1684 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
1687 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
1689 Warn about character literals not of length one.
1690 * NEWS (2.5): Document.
1691 * src/scan-gram.l (INITIAL): Remove comment that we don't check
1693 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
1694 * tests/input.at (Bad character literals): New test group.
1696 2009-07-24 Alex Rozenman <rozenman@gmail.com>
1698 Fix some memory leaks.
1699 * src/named-ref.c: Add a pointer check (named_ref_free).
1700 * src/scan-code.l: New function (variant_table_free). Called in
1702 * src/symlist.c: Call to named_ref_free (symbol_list_free).
1704 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
1706 * src/lalr.c (state_lookahead_tokens_count): Correct comment.
1708 2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
1710 Some M4 cleanup in the testsuite.
1711 Suggested by Eric Blake at
1712 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
1713 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
1714 complicate the code by distinguishing between a missing value
1715 and an empty string value for an optional argument. This fix is
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.
1721 Bison developers should use GNU M4 and should not use
1722 POSIXLY_CORRECT when building the test suite, so do not
1723 complicate the code by avoiding $10 and above.
1724 Do not quote an empty string value for an optional argument, and
1725 do not distinguish between a missing value and an empty string

1745 * src/reader.c: Factoring: assign_named_ref function.
1746 * src/scan-code.l: Factoring and style changes. Rename
1747 parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
1748 Use "unsigned" type for variant index. Improve readablity.
1749 * src/scan-gram.l: Change error messages and add comments.
1750 * src/symlist.h: symbol_list_null: New function decl.
1751 * src/symlist.c: symbol_list_null: Implement here.

1759 2009-06-29 Akim Demaille <demaille@gostai.com>
1761 build: avoid concurrent extraction of calc++.
1762 * examples/calc++/Makefile.am (calc.stamp): New.
1763 Depend on it to create the sources of calc++ so that concurrent
1764 builds don't launch several "extexi" in parallel.
1765 Not only this is inefficient, this also builds incorrect sources
1766 with several extractions mixed together.
1768 2009-06-29 Akim Demaille <demaille@gostai.com>
1771 * data/bison.m4: Move code related to specific variables after the
1772 definition of the variable-maintaining macros so that we don't
1773 "invoke" b4_percent_define_check_values before it is defined.
1775 2009-06-29 Akim Demaille <demaille@gostai.com>
1777 variables: parse.error
1779 Implement, document, and test the replacement of %error-verbose
1780 by %define parse.error "verbose".
1781 * data/bison.m4 (b4_error_verbose_if): Reimplement to track the
1782 values of the parse.error variable.
1783 Make "simple" its default value.
1784 Check the valid values.
1785 * src/parse-gram.y: Use %define parse.error.
1786 (PERCENT_ERROR_VERBOSE): New token.
1788 * src/scan-gram.l: Support %error-verbose.

1802 * src/reader.h: New argument for symbol_append and
1803 action_append functions.

1809 * src/scan-gram.l: Support bracketed id.
1810 * src/symlist.c: Store named refs in symbol lists.
1811 * src/symlist.h: New field in symbol list: named_ref.

1942 and update muscle_percent_define_insert invocations.
1943 * src/muscle-tab.h (muscle_percent_define_how): New enum type.
1944 (muscle_percent_define_insert): Add argument with that type.
1945 * src/muscle-tab.c (muscle_percent_define_insert): Implement
1946 -F/--force-define behavior and priorities.
1947 (muscle_percent_define_ensure): Update
1948 muscle_percent_define_insert invocation.

1956 Update some comments to make sense for -D.
1957 * data/bison.m4 (b4_check_user_names): In header comments, say
1958 "user occurrence" instead of "grammar occurrence".
1959 * src/muscle-tab.h (muscle_percent_define_insert): Likewise.
1960 (muscle_percent_code_grow): Likewise just for consistency.

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.

1976 remove useless variable.
1977 * src/getargs.c (skeleton_arg): Remove now useless variable.

2037 Convert underscores to dashes in some %define variable names.
2038 For now, just api.push-pull and lr.keep-unreachable-states.

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
2048 uses of tr so far, command-line arguments can be involved, and
2049 getargs.h is already included.

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
2559 different, and they are faster to compare.

2582 Use locations in the variant example.
2583 Yes, this obfuscates the point of this example, variants only.

2804 2008-12-11 Akim Demaille <demaille@gostai.com>
2806 Simplify the i18n of the error messages.
2807 * data/lalr1.cc: Comment changes.
2808 * data/yacc.c (yysyntax_error): Rewrite, using a switch as in

2811 2008-12-08 Akim Demaille <demaille@gostai.com>
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.

2848 Makefile properly updates atconfig when needed.
2850 2008-12-07 Di-an Jan <dianj@freeshell.org>
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):
2860 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
2861 to make user actions complete statements.

2866 2008-12-07 Akim Demaille <demaille@gostai.com>
2869 * gnulib: Update from master.
2871 2008-12-05 Eric Blake <ebb9@byu.net>
2873 Avoid compiler warning.

2877 2008-12-02 Eric Blake <ebb9@byu.net>
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 ')'.
2888 2008-12-01 Akim Demaille <demaille@gostai.com>
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

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.
2900 2008-12-01 Akim Demaille <demaille@gostai.com>
2902 Use b4_symbol_case_.
2903 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
2906 2008-12-01 Akim Demaille <demaille@gostai.com>
2908 Move b4_symbol based macro to bison.m4.

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.
2917 2008-12-01 Akim Demaille <demaille@gostai.com>
2919 b4_symbol/type_foreach.
2920 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
2923 2008-12-01 Akim Demaille <demaille@gostai.com>
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.
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.

2950 * data/bison.m4 (b4_syncline): Don't output an empty line before
2953 2008-11-26 Akim Demaille <demaille@gostai.com>
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.
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
2965 * lib/Makefile.am: Rename as...
2966 * lib/local.mk: this.
2967 Adjust to be prefixed.
2968 * Makefile.am, configure.ac: Adjust.

2971 2008-11-26 Akim Demaille <demaille@gostai.com>
2974 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...

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.
2984 2008-11-26 Akim Demaille <demaille@gostai.com>
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.

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.
3013 2008-11-26 Akim Demaille <demaille@gostai.com>
3016 * src/parse-gram.h, src/parse-gram.c: Regen.
3018 2008-11-26 Akim Demaille <demaille@gostai.com>

3032 2008-11-26 Akim Demaille <demaille@gostai.com>
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.
3038 * src/output.c (prepare_rules): Get rid of rhs and prhs.
3039 Adjust the computation of (yy)r2.
3041 2008-11-26 Akim Demaille <demaille@gostai.com>
3043 Rule length is unsigned.
3044 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
3046 2008-11-26 Akim Demaille <demaille@gostai.com>

3055 2008-11-26 Akim Demaille <demaille@gostai.com>
3057 Use yy* consistently.
3058 * data/glr.c: Now that yyrhs no longer exists as a global

3072 as an Autotest keyword.
3074 2008-11-25 Akim Demaille <demaille@gostai.com>
3076 Prefer TESTSUITE_FLAGS.
3077 TESTSUITEFLAGS is barely readable.
3079 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
3080 for backward compatibility.
3081 Use the former instead of the latter.
3083 2008-11-25 Akim Demaille <demaille@gostai.com>
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.
3089 2008-11-25 Akim Demaille <demaille@gostai.com>
3093 2008-11-25 Akim Demaille <demaille@gostai.com>
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
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
3110 2008-11-25 Akim Demaille <demaille@gostai.com>
3113 The point is to factor the generation of the tables across skeletons.
3114 This is language dependant.
3116 * data/c.m4 (b4_comment_): New.
3117 Should be usable to define how to generate tables independently of

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)
3132 2008-11-25 Akim Demaille <demaille@gostai.com>
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
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

3168 2008-11-20 Di-an Jan <dianj@freeshell.org>
3170 Improves options in the manual.
3171 * doc/bison.texinfo (-g, -x): Add space before argument.
3172 (Option Cross Key): Implement FIXME: listing directives also.
3173 * build-aux/cross-options.pl: Read from <STDIN> rather than <>.
3174 (Short Option): Special case -d. Put arguments inside @option.

3176 src/scan-gram.l (actual name passed as the first argument)
3177 with special case for %define.
3178 * doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l

3186 Reported by Csaba Raduly at
3187 <http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00048.html>.
3188 * THANKS (Csaba Raduly): Add.
3189 * data/glr.c: Fix overquoting on b4_prefix for yylval and yylloc.
3190 * tests/calc.at (_AT_DATA_CALC_Y): If %defines is specified, generate
3191 lexer in a separate module that includes the defines file.

3294 2008-11-15 Akim Demaille <demaille@gostai.com>
3296 Support parametric types.
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> > >.
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 '['.
3307 * src/scan-gram.l (brace_level): Rename as...
3310 Implement support for complex tags.
3313 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
3314 (b4_symbol_variant): Leave space around types as parameters.
3315 * examples/variant.yy: Use nested template types and leading ::.
3316 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
3318 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.

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

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

3430 * Makefile.am, configure.ac: Adjust.
3431 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on

3485 Provide convenience constructors for locations and positions.
3486 * data/location.cc (position::position): Accept file, line and

3488 Always qualify initial line and column literals as unsigned.
3489 (location::location): Provide convenience constructors.
3491 2008-11-15 Akim Demaille <demaille@gostai.com>
3493 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
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.
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.
3514 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
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.
3526 2008-11-13 Akim Demaille <demaille@gostai.com>
3528 Compute at M4 time some of the subtractions.
3529 * data/lalr1.cc (b4_subtract): New.
3530 (b4_rhs_data): Use it.
3532 2008-11-13 Akim Demaille <demaille@gostai.com>
3535 This allows the user to get the type of a token returned by yylex.
3537 * data/lalr1.cc (symbol::token): New.
3538 (yytoknum_): Define when %define lex_symbol, independently of
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).
3546 2008-11-13 Akim Demaille <demaille@gostai.com>
3549 * TODO (YYERRCODE): Mention the case of $undef.

3554 * TODO (YYPRINT): New.
3556 2008-11-13 Akim Demaille <demaille@gostai.com>
3559 * data/lalr1.cc, data/yacc.c: Fix the description of the
3560 yytranslate and yytoknum tables.
3562 2008-11-13 Akim Demaille <demaille@gostai.com>
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
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.
3576 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3583 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3591 The stack_symbol_type does not need to be moved, it is used only
3594 * data/lalr1.cc: Move symbol_type and symbol_base_type
3595 constructors into...
3596 (b4_symbol_constructor_definitions): here.
3599 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3605 * data/lalr1.cc (b4_yytranslate_definition): New.
3608 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3615 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3625 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
3626 expect a token_type.
3628 2008-11-13 Akim Demaille <demaille@gostai.com>
3630 Honor lex-params in %define lex_symbol mode.
3631 * data/lalr1.cc: Use b4_lex_param.
3633 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
3640 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
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
3651 Adjust its caller for new-line issues.
3653 2008-11-13 Akim Demaille <demaille@gostai.com>
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.
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.
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"
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.
3673 2008-11-11 Akim Demaille <demaille@gostai.com>
3675 Locations are no longer required by lalr1.cc.
3676 * data/lalr1.cc (_b4_args, b4_args): New.
3677 Adjust all uses of locations to make them optional.
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.
3683 * tests/output.at: Check lalr1.cc with and without location
3685 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
3686 Don't use locations.
3688 2008-11-11 Akim Demaille <demaille@gostai.com>
3691 * tests/local.at (AT_FULL_COMPILE): New.
3692 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.

3696 Support parens in calc++.
3697 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
3698 * examples/calc++/test (run): Check the expected output.

3705 * data/lalr1.cc: Remove useless calls to b4_defines_if.
3707 2008-11-11 Akim Demaille <demaille@gostai.com>
3710 * TODO (yysyntax_error): New item.
3712 2008-11-11 Akim Demaille <demaille@gostai.com>
3715 * data/lalr1.cc: Use b4_error_verbose_if instead of #if

3720 Support i18n of the parse error messages.
3721 * TODO (lalr1.cc/I18n): Remove.
3722 * data/lalr1.cc (yysyntax_error_): Support the translation of the
3723 error messages, as done in yacc.c.
3724 Stay within the yy* pseudo namespace.
3726 2008-11-11 Akim Demaille <demaille@gostai.com>
3729 * TODO (single stack, yysyntax_error): New.
3731 2008-11-11 Akim Demaille <demaille@gostai.com>
3733 Make it possible to return a symbol_type from yylex.
3734 * data/lalr1.cc (b4_lex_symbol_if): New.
3735 (parse): When lex_symbol is defined, expected yylex to return the
3737 * etc/bench.pl.in (generate_grammar_list): Extend to support this
3739 (bench_variant_parser): Exercise it.
3741 2008-11-11 Akim Demaille <demaille@gostai.com>
3743 Remove useless bench case.
3744 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is

3749 Improve display of directives.
3750 * etc/bench.pl.in (parse_term): Don't add useless eol.
3752 2008-11-11 Akim Demaille <demaille@gostai.com>
3754 Use string_cast in the bench.
3755 * etc/bench.pl.in (generate_grammar_list): Define and use
3758 2008-11-11 Akim Demaille <demaille@gostai.com>
3760 Replace yychar with a Boolean.
3761 * data/lalr1.cc (parse::yychar): Replace by...
3762 (parse::yyempty): this.
3764 2008-11-11 Akim Demaille <demaille@gostai.com>
3769 2008-11-11 Akim Demaille <demaille@gostai.com>
3771 Let yytranslate handle the eof case.
3772 * data/lalr1.cc (yytranslate_): Handle the EOF case.
3774 No longer expect yychar to be equal to yyeof_, rather, test the
3775 lookahead's (translated) kind.
3777 2008-11-11 Akim Demaille <demaille@gostai.com>
3779 yychar cannot be empty in yyerrlab.
3780 * TODO (yychar == yyempty_): New.
3781 * data/lalr1.cc: Remove the handling of this case.
3782 This eases forthcoming changes related to yychar and yytranslate.
3784 2008-11-11 Akim Demaille <demaille@gostai.com>

3792 2008-11-11 Akim Demaille <demaille@gostai.com>
3794 Less memory pressure on the "list" bench.
3795 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
3796 the values, to limit memory pressure.
3798 2008-11-11 Akim Demaille <demaille@gostai.com>
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.
3809 * data/lalr1.cc (b4_symbol_constructor_declaration_)
3810 (b4_symbol_constructor_declarations)
3811 (b4_symbol_constructor_specialization_)
3812 (b4_symbol_constructor_specializations)
3813 (b4_symbol_constructor_definition_)
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
3822 (symbol_type): Now public, so that functions such as yylex can use
3825 2008-11-11 Akim Demaille <demaille@gostai.com>
3827 Inform m4 whether a tag is a valid id.
3828 * src/output.c (is_identifier): New.
3829 (symbol_definitions_output): Use it to define tag_is_id.
3830 But maybe this should be done at m4 level?
3832 2008-11-11 Akim Demaille <demaille@gostai.com>
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.
3840 * data/java.m4, data/lalr1.java: Untabify.
3841 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
3842 tabulations are no longer generated.
3844 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
3846 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
3847 * configure.ac: Adjust usage.
3848 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
3849 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
3850 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
3852 2008-11-10 Di-an Jan <dianj@freeshell.org>
3854 Workaround Java's ``code too large'' problem for parser tables
3855 in most cases, by using one function per initialization.
3856 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
3857 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,

3870 using gcj < 4.3 in the testsuite, according to comments in
3871 gnulib/m4/javacomp.m4.
3872 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
3873 location_type, position_type): Remove extraneous brackets from
3874 b4_percent_define_default.
3875 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
3876 m4_define and m4_define_default.
3877 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
3878 which marks the end of user code with appropriate syncline, like all
3879 the other skeletons.
3880 (b4_user_post_prologue): Add. Don't silently drop.
3882 (parse): Inline yylex.
3883 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
3884 (%{...%}): Fix typo of %code imports.
3885 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
3887 Support annotations on parser class with %define annotations.

3901 about %error-verbose having no effect.
3902 (getErrorVerbose, setErrorVerbose): Document.
3904 Move constants for token names to Lexer interface.
3905 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
3906 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
3907 (parse): Qualify EOF to Lexer.EOF.
3908 * doc/bison.texinfo (Java Parser Interface): Move documentation of
3909 EOF and token names to Java Lexer Interface.
3910 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
3912 Make yyerror public.
3913 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
3914 (yyerror): Change to public. Add Javadoc comments. Use longer
3915 parameter names. Make the body rather than the declarator
3916 conditional on %locations.
3917 * doc/bison.texinfo (yyerror): Document. Don't mark as protected.

3930 2008-11-10 Akim Demaille <demaille@gostai.com>
3933 * TODO (-D): is implemented.
3934 (associativity): Same precedence must have the same associativity.
3935 For instance, how can a * b / c be parsed if * is %left and / is
3937 (YYERRORCODE, YYFAIL, YYBACKUP): New.
3939 2008-11-10 Akim Demaille <demaille@gostai.com>
3943 2008-11-10 Akim Demaille <demaille@gostai.com>
3945 More information about the symbols.
3946 * src/output.c (type_names_output): Document all the symbols,
3947 including those that don't have a type-name.
3948 (symbol_definitions_output): Define "is_token" and
3950 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
3951 type-name, now that they are defined too in b4_type_names.
3953 2008-11-10 Akim Demaille <demaille@gostai.com>
3957 2008-11-10 Akim Demaille <demaille@gostai.com>
3959 Make parser::yytranslate static.
3960 Small speedup (1%) on the list grammar. And makes yytranslate_
3961 available in non member functions.
3963 * data/lalr1.cc (yytranslate_): Does not need to be a instance
3966 2008-11-10 Akim Demaille <demaille@gostai.com>
3968 Avoid trailing spaces.
3969 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
3970 * data/lalr1.cc: Don't indent before rule and symbol actions, as
3971 they can be empty, and anyway this incorrectly indents the first
3974 2008-11-10 Akim Demaille <demaille@gostai.com>
3978 2008-11-10 Akim Demaille <demaille@gostai.com>
3980 Use "enum" for integral constants.
3981 This is just nicer to read, I observed no speedup.
3983 * data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
3984 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
3985 (yyuser_token_number_max_, yyundef_token_): Move into...

4020 2008-11-10 Akim Demaille <demaille@gostai.com>
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.
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
4036 * src/output.c (type_names_output): Remove.
4037 (symbol_numbers_output, symbol_definitions_output): New.
4038 (muscles_output): Call them.
4039 (prepare_symbols): Define b4_symbols_number.
4041 2008-11-10 Akim Demaille <demaille@gostai.com>

4045 (trace_types, trace_args): Support it.
4046 * src/output.c (output_skeleton): Use it.
4048 2008-11-10 Akim Demaille <demaille@gostai.com>
4051 * src/output.c (muscles_output): New, extracted from...
4052 (output_skeleton): here.

4059 2008-11-10 Akim Demaille <demaille@gostai.com>
4061 Update the variant example.
4062 * examples/variant.yy: Formatting changes.
4065 2008-11-10 Akim Demaille <demaille@gostai.com>
4067 Support constructor with an argument.
4068 This improves the "list" bench by 2%.
4070 * data/lalr1.cc (variant::build): Add an overloaded version with
4072 * tests/c++.at (AT_CHECK_VARIANT): Check it.
4074 2008-11-10 Akim Demaille <demaille@gostai.com>
4077 * tests/c++.at (AT_CHECK_VARIANTS): New.
4078 Use it with and without %define assert.
4080 2008-11-10 Akim Demaille <demaille@gostai.com>
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,
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.
4092 * doc/bison.texinfo: Document %precedence.
4093 (Precedence Only): New.
4094 * src/assoc.h, src/assoc.c (precedence_assoc): New.
4095 * src/conflicts.c (resolve_sr_conflict): Support it.
4096 * src/scan-gram.l, src/parse-gram.y (%precedence): New token.
4098 * tests/calc.at: Use %precedence for NEG.
4099 * tests/conflicts.at (%precedence does not suffice)
4100 (%precedence suffices): New tests.

4161 (getopts): Support -d, --directive.
4163 2008-11-09 Akim Demaille <demaille@gostai.com>
4165 Use inline for small operations.

4169 (yy_destroy_): Inline.
4171 2008-11-09 Akim Demaille <demaille@gostai.com>

4177 Derive from symbol_base_type.

4182 (yydestruct_): Rename as...
4183 (yy_destroy_): this.
4184 (b4_symbols_actions, YY_SYMBOL_PRINT): Adjust.
4185 (parser::parse): yyla is now of symbol_type.
4186 Use its type member instead of yytoken.

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

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
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
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.
4369 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

4646 2008-11-03 Akim Demaille <demaille@gostai.com>
4648 Fuse the three stacks into a single one.
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
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.
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).
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.
4670 These changes should probably benefit the C parser too.
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
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.
4682 2008-11-03 Akim Demaille <demaille@gostai.com>
4684 Push the state, value, and location at the same time.
4685 This is needed to prepare a forthcoming patch that fuses the three
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.
4696 2008-11-03 Akim Demaille <demaille@gostai.com>
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.

4702 Take the value and location as references.
4705 2008-11-03 Akim Demaille <demaille@gostai.com>

4708 * data/lalr1.cc (stack::height): Rename as...
4709 (stack::size): this.
4710 Fix the output type.
4713 2008-11-03 Akim Demaille <demaille@gostai.com>
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).
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.
4726 * src/output.c (type_names_output): New.
4727 (output_skeleton): Invoke it.

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.
4740 2008-11-03 Akim Demaille <demaille@gostai.com>
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.

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

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

5255 2008-04-23 Eric Blake <ebb9@byu.net>
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.

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
5270 ("Output file name: )"): Likewise.
5272 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5274 * GNUmakefile: Update git-version-gen invocation so make dist
5277 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5279 Update to the current gnulib CVS repository, and fix trigraph handling
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.

5314 long and short options more completely. Document --defines and -d
5315 separately since the former takes an argument but, for POSIX Yacc, the
5317 (short_options): Let -W take an optional argument like --warnings.

6203 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
6205 In impure push mode, don't allow more than one yypstate to be allocated
6206 since multiple impure parsers would corrupt yynerrs.
6207 * data/push.c (yypstate_allocated): New static global variable
6209 (yypull_parse): If yypstate_new returns 0, don't report it as memory
6210 exhaustion if yypstate_allocated is 1, but still return 2.
6211 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is

6288 Get rid of broken %no-parser, -n, and --no-parser implementation and
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
6303 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
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
6311 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6319 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6320 node names: say "Decl Summary" not "Bison Declaration Summary".
6322 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6330 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6342 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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
6366 * src/main.c (main): Don't depend on C99 features.
6368 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
6370 * build-aux/.cvsignore: Add compile.
6371 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
6374 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
6376 * bootstrap (slurp): Create target directories that don't exist.
6377 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
6379 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6381 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
6383 * closure.c (closure): Likewise.
6384 * state.h (reductions): Comment sorting of rules.
6385 (state): Comment sorting of items.
6387 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
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
6394 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
6395 rather than AT_DATA so that config.h is included.
6397 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6404 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6406 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
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.
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.
6419 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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
6443 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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.
6460 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
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>.
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.
6471 * NEWS (2.3a+): In the %code entry, reference section `Bison
6472 Declaration Summary' from the manual now since the %code summary has
6474 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
6475 in the rules section must be terminated by semicolons.
6477 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
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
6484 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

6488 (muscle_percent_define_get, muscle_percent_define_ifdef): New
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):
6498 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6507 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
6509 If conflict resolution makes states unreachable, remove those states,
6510 report rules that are then unused, and don't report conflicts in those
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

6527 an unused rule is discovered.
6529 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
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.

6545 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
6547 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
6548 still sticks to ASCII. Sorry!

6551 for Bison. Contains much of the contents of:
6552 * README-cvs: Remove.

6561 (Java Differences): Fix some typos.
6562 * THANKS: Add Sebastian Setzer.
6564 2007-03-07 Paolo Bonzini <bonzini@gnu.org>
6566 * data/java.m4 (b4_single_class_if): Remove.
6567 (b4_abstract_if): Look at "%define abstract".
6569 (b4_union_name): Rename...
6570 (b4_yystype): ... to this. Map to "%define stype".
6571 (b4_rhs_value, b4_parse_param_decl, b4_lex_param_decl,
6572 b4_maybe_throws): Fix quoting.
6573 (b4_lex_param_call): Move below to keep b4_*_param_decl close.

6597 (AT_BISON_OPTION_POPDEFS): Pop it.
6599 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
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.
6608 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6610 Miscellaneous %define and %code cleanup.

6612 values are interpreted.
6613 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
6614 documentation a little more.

6616 muscle_percent_define_insert, muscle_percent_code_grow): New
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.
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
6629 b4_percent_define_skeleton_variables(VARIABLE) to

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.
6639 For %define variables, report locations for invalid values and
6641 * data/bison.m4 (b4_percent_define_flag_if): Read
6642 b4_percent_define_loc(VARIABLE) to report the location of an invalid
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
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.

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
6668 (print_results): Don't allocate lookahead_set.
6670 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
6672 * data/lalr1.java: Prefix all private members with yy.
6674 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6684 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
6686 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.

6694 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
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"
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.
6709 2007-02-11 Bruno Haible <bruno@clisp.org>
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.
6716 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
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
6728 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
6739 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
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.
6754 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
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.
6760 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
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.
6767 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
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,
6774 * src/getargs.c: Include c-strcase.h.
6775 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
6776 to avoid unspecified behavior.
6778 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
6780 * doc/bison.texinfo (Decl Summary): Correct typo.
6782 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
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
6790 * tests/input.at (Boolean %define variables): Test new behavior.
6792 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
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.
6799 * data/Makefile.am: Add new files.
6800 * data/java-skel.m4: New.
6801 * data/java.m4: New.
6802 * data/lalr1.java: New.
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.
6808 * src/getargs.c (valid_languages): Add Java.
6809 * src/getargs.h (struct bison_language): Update size of string fields.
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.
6816 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
6839 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
6856 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
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
6865 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
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.
6876 * doc/bison.texinfo (Decl Summary): Document %define.
6878 * src/parse-gram.y (Unqualified %code): Change muscle name to
6880 (content.opt): Default to empty.
6882 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
6901 * bootstrap: Update copyright to 2007.
6903 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
6905 * bootstrap: Remove occurrences of .#bootmp from the files.
6907 2007-01-17 Akim Demaille <akim@epita.fr>
6909 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
6911 Use per-type %printer.
6913 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
6915 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

6923 2007-01-16 Akim Demaille <akim@epita.fr>
6925 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
6927 (Calc++ Scanner): Exit with failure if we can't open the input
6929 Accept "-" standing for stdin.
6930 (Calc++ Top Level): Print the result only if the parsing was
6933 2007-01-16 Akim Demaille <akim@epita.fr>
6935 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
6937 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
6938 and Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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
6976 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6978 DJGPP specific issues.
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.
6983 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
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.
6991 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7000 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7010 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
7011 and Joel E. Denny <jdenny@ces.clemson.edu>
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
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
7033 (grammar_declaration): For %union RHS, use `braceless' instead of
7034 "{...}" so that braces are already stripped and code is escaped with
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.
7041 * data/c.m4: Remove stray parenthesis.
7043 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
7063 (variable): New nonterminal that takes an `ID' or a `STRING'.
7064 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
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.
7070 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7077 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
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):
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):
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.
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.
7134 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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.
7160 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
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
7171 * src/location.c, src/location.h (boundary_set_from_string): New global
7173 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
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
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(...@)
7188 * tests/input.at (Reject bad %code qualifiers): Update test output with
7189 locations and extend.
7191 * tests/output.at (Output file name: [, Output file name: ]): Remove
7192 bogus comment about these tests failing.
7194 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
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
7203 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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
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
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
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
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
7258 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
7259 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
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.
7265 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7304 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
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):
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
7342 (symbol_print): Use SYMBOL_CODE_PRINT.
7344 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7357 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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.
7377 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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
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
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.
7424 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7426 * etc/.cvsignore: New.
7428 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7444 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
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
7454 (Exploding the Stack Size with Malloc): Likewise.
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.
7468 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
7488 Remove the yylexp argument and hard-code yylex invocation instead.
7489 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
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
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.
7508 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7533 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7546 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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.
7572 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7586 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
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
7597 (gottoken): Rename label to...
7598 (yyread_pushed_token): ... for clarity and to avoid infringing on the
7601 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
7627 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7636 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
7663 Remove all code that copies between the local parser state variables
7666 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
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.
7675 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
7676 and Joel E. Denny <jdenny@ces.clemson.edu>
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@'.
7697 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7699 * NEWS: Reword the %language news a bit, and put it earlier.
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
7708 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
7710 * src/complain.c (program_name): Remove decl; no longer needed.
7711 * src/main.c (program_name): Remove; now belongs to getargs.
7713 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
7715 * NEWS: Document %language.
7717 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
7719 * data/c-skel.m4, data/c++-skel.m4: New files.
7720 * data/glr.c: Complain on push parsers.
7722 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
7724 (Decl Summary): Document %language and %skeleton.
7725 (Command line): Document -L.
7727 * examples/extexi: Rewrite %require directive.
7728 * examples/calc++/Makefile.am: Pass VERSION to extexi.
7730 * src/files.c (compute_exts_from_gc): Look in language structure
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.
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.
7751 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
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.
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
7763 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
7773 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
7774 (yy_reduce_print): Reformat M4 for readability.
7776 2006-12-15 Bob Rossi <bob@brasko.net>
7777 and Joel Denny <jdenny@ces.clemson.edu>
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.
7783 2006-12-14 Bob Rossi <bob@brasko.net>
7785 * data/push.c (yypush_parse): Declare prototype regardless of
7788 2006-12-14 Bob Rossi <bob@brasko.net>
7790 * data/push.c (yyparse): Remove the prototype and the #define when in
7793 2006-12-13 Bob Rossi <bob@brasko.net>
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.
7802 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
7804 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
7805 strange test case titles. Reported by Bob Rossi.
7807 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
7809 * TODO: Add pointer to Sylvain Schmitz's work on static detection
7810 of potential ambiguities in GLR grammers.
7812 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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
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
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
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.
7854 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
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

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.

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

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.

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.
8082 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8084 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

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.

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

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 ...):
8321 * tests/regression.at (Braced code in declaration in rules section):
8323 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
8324 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
8325 Include <config.h> unconditionally.
8327 * bootstrap: Sync from coreutils, as follows:
8329 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
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.
8335 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8337 * bootstrap (usage, main program, symlink_to_gnulib): Add option
8338 --copy. Inspired by a suggestion from Bruno Haible.
8340 2006-10-03 Jim Meyering <jim@meyering.net>
8342 * bootstrap: Undo last change to this file, since now gnulib-tool
8343 sticks with the automake default in generating dependencies.
8345 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8347 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
8348 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
8350 * doc/bison.1: Add copyright notice.
8352 * data/glr.c: Don't include <stdarg.h>; not used.

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.
8379 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
8380 accommodates the 2006-10-08 change.
8382 2006-10-11 Bob Rossi <bob@brasko.net>
8384 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
8385 (b4_yyssa, b4_yyerror_range): New macros.
8386 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
8387 (yypvarsinit): Remove init of removed fields.
8388 (yypushparse): Remove use of removed fields; use new macros instead.
8390 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8392 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
8393 in a push parser. Reindent slightly to match yacc.c better.
8395 2006-10-11 Bob Rossi <bob@brasko.net>
8397 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
8399 (yypvarsinit, yypushparse): Remove init of removed fields.

8404 * THANKS: Add Paolo Bonzini and Bob Rossi.
8406 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
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
8419 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
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.

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.
8446 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
8448 Merge bootstrap changes from coreutils.
8450 2006-09-28 Jim Meyering <jim@meyering.net>
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.
8457 2006-09-23 Jim Meyering <jim@meyering.net>
8459 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
8461 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8463 * bootstrap: Add support for --force.
8464 (usage): New function. Describe usage less tersely.
8465 (CVS_only_file): New var.

8476 (YYPUSH_MORE): Add #define.
8477 (yypushparse): Modify return value.
8479 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
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,
8487 Sync bootstrap from coreutils, as follows:
8489 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
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).
8498 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
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.
8504 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
8506 Use some of gnulib's new modules, taken from coreutils.
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.
8516 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
8518 (GNULIB_AUTOCONF_SNIPPET): Remove.
8519 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
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.
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>.
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.
8553 * src/scan-code.l: Always initialize braces_level; the old code
8554 left it uninitialized and therefore had undefined behavior.
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
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.
8567 2006-09-15 Bob Rossi <bob@brasko.net>
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.
8585 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
8587 * NEWS: Version 2.3a.
8588 * configure.ac (AC_INIT): Likewise.
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
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
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
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
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.
8617 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
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.
8625 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
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.
8631 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
8651 * README-cvs: Fix typo: "&" should be "&&". Problem reported
8653 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
8654 This adjusts to recent gnulib changes.
8656 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
8658 Finish implementation of per-type %destructor/%printer. Discussed
8660 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
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
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.
8685 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
8709 * tests/actions.at, tests/input.at: Add %symbol-default to all default
8710 %destructor/%printer declarations.
8712 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
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). $end is defined by Bison whereas any other token with token
8719 number 0 is defined by the user. The error token is always defined by
8720 Bison regardless of whether the user declares it with %token, but we
8721 may one day let the user define error as a nonterminal instead.
8722 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
8723 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
8724 the meaning of "user-defined".
8725 * tests/actions.at (Default %printer and %destructor for user-declared
8726 end token): Rename to...
8727 (Default %printer and %destructor for user-defined end token): ...
8730 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
8731 computation of whether to apply the default, don't maintain a list of
8732 every Bison-defined symbol. Instead, just check for a first character
8733 of '$', which a user symbol cannot have, and check for the error token.
8735 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
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
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):
8747 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
8759 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
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.
8774 * tests/regression.at (Undeclared string literal): Remove test case
8775 added in previous commit since non-aliased string literals are allowed
8777 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
8778 remove unnecessary string literal declarations.
8779 * tests/sets.at (Firsts): Likewise.
8781 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
8804 * tests/sets.at (Firsts): Likewise.
8806 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
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
8816 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
8819 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
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
8827 * tests/input.at (String aliases for character tokens): New test.
8829 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
8831 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
8833 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
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).
8842 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
8843 function, since it simplifies our code a bit.
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.
8852 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
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".
8864 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
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
8874 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
8876 * doc/bison.texinfo: Fix some typos.
8878 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
8888 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
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 $end. Discussed starting at
8895 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
8896 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
8898 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
8899 * NEWS (2.3+): Mention.
8900 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
8901 declare a %destructor for a mid-rule's semantic value. It's just
8902 impossible to declare one specific to it.
8903 (Freeing Discarded Symbols): Mention that @$ 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
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.
8932 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
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>
8938 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
8940 Make the skeletons consistent in how they pop the end token and invoke
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.
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.
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
8959 * tests/actions.at (Printers and Destructors): Test all the above.
8961 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
8963 Update to latest gnulib and gettext versions.
8964 * bootstrap (gnulib-modules): Remove hard-locale, stdio-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
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,
8983 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
8984 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
8986 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
8988 * bootstrap: Adjust to today's change to gnulib-tool by invoking
8989 it with --assume-autoconf='latest-stable'.
8991 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
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
8996 * src/muscle_tab.h (muscle_grow): Replace the header comments with
8997 those from muscle_tab.c since the old ones are misleading.
8999 2006-07-13 Akim Demaille <akim@epita.fr>
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.
9010 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
9012 * src/scan-gram.l (getargs.h): Don't include it.
9014 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
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.
9024 2006-07-12 Akim Demaille <akim@epita.fr>
9026 * data/c.m4: Comment changes.
9028 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
9030 * src/complain.c (error_message, ERROR_MESSAGE): New.
9032 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
9033 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
9035 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
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
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.
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.
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.
9069 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
9070 object is now static.
9072 * src/getargs.c (flags_argmatch): Return void, not int,
9073 to pacify ./configure --enable-gcc-warnings.
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).
9078 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9080 Implement --warnings/-W.
9081 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
9083 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
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.
9091 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
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.
9099 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9101 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
9102 to be in alphabetical order.
9103 (trace_args): Spelling fixes.
9105 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
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.
9113 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
9115 * data/c.m4 (b4_basename): Simplify a bit, since we don't
9116 need the full POSIX semantics (and weren't implementing them
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
9129 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
9130 Do not check for uintptr_t, since new stdint module does the right
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
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>
9155 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9157 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
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
9162 * tests/calc.at: Adjust.
9164 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9166 * data/c.m4 (b4_basename): New.
9167 (b4_syncline): Also output the location of its invocation (from
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.
9174 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
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.
9181 * src/scan-gram.l (scanner_cursor): Declare it static.
9183 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9185 In warnings, say "previous declaration" rather than "first
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.
9195 2006-06-27 Akim Demaille <akim@epita.fr>
9197 * doc/Doxyfile.in: New.
9198 * doc/Makefile.am: Use it.
9199 * src/lalr.h, src/symtab.h: Initial doxygenation.
9201 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
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
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
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.
9221 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
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>
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
9230 * src/reader.c (grammar_current_rule_end): Don't invoke
9231 grammar_rule_check yet since not all symbol declarations may have been
9233 (grammar_midrule_action): Likewise.
9234 Don't record whether the midrule's $$ has been used yet since actions
9235 haven't been translated yet.
9236 Record the midrule's parent rule and its RHS index within the parent
9238 (grammar_current_rule_action_append): Don't translate the action yet
9239 since not all symbol declarations may have been parsed yet and, thus,
9240 warnings about types for $$, $n, @$, 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
9251 * src/symlist.c (symbol_list_new): Initialize new midrule-related
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
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.
9269 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
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.
9280 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
9282 Clean up yesterday's patch.
9283 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
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.
9290 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
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
9300 * tests/regression.at (Braced code in declaration in rules section):
9301 New test to catch the error fixed by the above patch.
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
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
9315 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.
9359 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
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.
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
9375 * tests/input.at (Incompatible Aliases): Update output with correct
9378 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
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>,
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
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
9436 2006-06-20 Akim Demaille <akim@epita.fr>
9438 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
9439 (symbol_get): Use it.
9440 * src/parse-gram.y: Use it.
9442 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
9444 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
9445 build succeeds when configured with --enable-gcc-warnings.
9447 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
9468 2006-06-19 Akim Demaille <akim@epita.fr>
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'.
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.
9486 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
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>,
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
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.
9509 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
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
9519 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
9521 For consistency, use `lookahead' instead of `look-ahead' or
9522 `look_ahead'. Discussed starting at

9537 count_rr_conflicts, conflicts_free): Update uses.
9538 * src/getargs.c (report_args): Move "lookahead" before alternate

9598 * TODO: Add request from Nelson H. F. Beebe to be able to install
9599 Bison without installing the yacc script.
9601 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
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
9610 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
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
9615 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
9616 loc argument as it shadows a global.

9634 2006-06-06 Akim Demaille <akim@epita.fr>
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
9640 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
9641 * src/scan-gram.l (add_column_width, adjust_location): Move to and
9643 * src/location.h, src/location.c (add_column_width)
9644 (location_compute): these.

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.

9667 (YY_DECL): Rename as...
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):

9697 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
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>.
9703 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
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.

9725 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
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>.

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
9740 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>

9743 Problem reported by Akim Demaille.

9749 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
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>.
9755 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
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.
9764 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
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
9771 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
9773 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
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.
9788 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
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).
9802 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9804 * NEWS: Version 2.2.
9805 * configure.ac (AC_INIT): Likewise.
9807 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
9809 * data/glr.c (yyreportTree): Make room in yystates for the state
9810 preceding the RHS. This fixes the segmentation fault reported by Derek
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
9816 * THANKS: Add Derek M. Jones.
9817 Update my email address.
9818 Fix typo in Steve Murphy's name.
9820 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
9839 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9841 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
9843 Reported by Steve Murphy.
9845 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9847 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
9848 * data/glr.cc: b4_location_flag is now b4_locations_flag.
9850 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
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.
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.
9866 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9868 * etc/bench.pm: Shorten bench names.
9870 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9872 * src/output.h, src/output.c (error_verbose): Move to...
9873 * src/getargs.h, src/getargs.c: here.
9875 Adjust dependencies.
9877 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
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.
9885 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9887 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
9888 incompatibility, not a bug. Mention that it wasn't fixed as of
9891 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9893 * examples/extexi: Enforce the precedence of concatenation over
9895 Reported by Tommy Nordgren.
9897 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9899 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
9900 with the member "token".
9901 Reported by Martin Nylin.
9903 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
9905 * data/glr.c: Switch to Bison 2.2 special-exception language in
9906 the copyright notice. Use more-regular format for titles and
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.
9914 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
9916 * data/glr.cc: Remove dead code.
9918 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
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.
9924 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

9928 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
9930 * etc/README, etc/bench.pl: New.
9932 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
9934 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
9936 Reported by Mickael Labau.
9937 * tests/input.at (Torturing the Scanner): Test it.
9939 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
9941 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
9942 Problem reported by Bob Rossi.
9944 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
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.
9951 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
9953 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
9954 of AT_NAME_PREFIX when %name-prefix is not used.
9956 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
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'.

9991 Fix two nits reported by twlevo, plus one more that I discovered.
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.
9997 * src/reader.h (token_name): Likewise.
9999 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
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
10006 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
10007 * src/conflicts.c (solved_conflicts_obstack): Now static.
10009 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
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.
10015 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
10029 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
10031 * tests/glr-regression.at (Uninitialized location when reporting
10032 ambiguity): New test case.
10033 * data/glr.c (yyresolveLocations): New function, which uses
10035 (yyresolveValue): Invoke yyresolveLocations before reporting an
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.
10041 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
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
10047 * data/glr.c (yyparse): Check for zero stacks remaining before
10048 attempting to shift the lookahead so that you don't lose it.
10050 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
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.
10061 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
10062 in existing testcases.
10064 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
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
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.

10091 led to a segmentation fault in GNU Pascal. Problem reported
10094 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
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

10117 * configure.ac (AC_INIT): Bump version number.
10119 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
10121 * NEWS: Version 2.1a.
10122 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
10123 since C99 requires this.
10125 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
10127 * m4/c-working.m4: New file.
10128 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
10130 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
10132 * Makefile.maint: Merge from coreutils.

10136 More portability fixes for problems summarized by Nelson H. F. Beebe.
10138 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
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

10147 More portability fixes for problems summarized by Nelson H. F. Beebe.
10149 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
10150 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
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++

10160 More portability fixes for problems summarized by Nelson H. F. Beebe.
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.

10185 that '#include <string>' works.
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
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

10200 -E" works; it apparently doesn't work with PathScale EKO Compiler

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
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
10220 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
10221 after `--report' documentation.

10225 * src/parse-gram.y (grammar_declaration): Location of printer
10226 symbol is @1, not list->location. Bug reported by twlevo.

10229 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
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
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.

10252 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
10253 rule already has an action.
10254 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
10255 * tests/input.at (AT_CHECK_UNUSED_VALUES):
10256 Add some tests to check that the above changes fixed the bug.
10258 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
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
10267 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
10269 Work around a bug in bro 0.8, which underparenthesizes its

10278 Work around a bug in Pike 7.0, and give the Pike folks a
10279 better way to override the usual int widths.

10281 user can override the types.
10282 (short): #undef, to work around a bug in Pike 7.0.
10283 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
10284 (union yyalloc.yyss): Use yytype_int16 rather than short.
10286 (yysigned_char): Remove.
10287 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
10288 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

10291 * src/reader.c (check_and_convert_grammar): New function.
10292 (reader): Close the input file even if something went wrong during
10293 parsing. Minor file descriptor leak reported by twlevo.

10296 to pacify gcc -Wswitch-default.
10297 * src/scan-gram.l (adjust_location): Use a default: break; case
10298 to pacify gcc -Wswitch-default.

10302 Move these decls to scan-skel.l, since they don't need to be
10304 * src/scan-skel.l: Accept the above decls.
10305 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31

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.
10314 (sc_trailing_blank): Renamed from sc_trailing_space.

10483 * data/glr-regression.at (Incorrect lookahead during nondeterministic

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
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
10516 (Table of Symbols): In the yychar entry, don't call it the `current'
10518 In the yylloc and yylval entries, mention look-ahead usage.

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
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

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.

10560 to print a semantic value.
10562 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10564 * tests/glr-regression.at: For consistency with my newer test cases,
10565 don't thank myself.
10567 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
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

10625 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain

10627 not require a diagnostic when the grammar uses extensions.
10629 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
10631 Warn about dubious constructions like "%token T T".
10632 Reported by twlevo.

10654 * data/glr.cc (b4_parse_param_orig): New.
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
10659 Simplify the generation of auxiliary functions: locations and
10660 purity are mandated.
10661 (b4_global_tokens_and_yystype): Honor it.

10699 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
10700 (rule_length_overflow, increment_rule_length, add_column_width):
10702 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
10703 (<SC_BRACED_CODE>"}"):
10704 Use increment_rule_length rather than incrementing it by hand.

10717 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
10719 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
10720 Remove unnecessary forward static decls.

10733 being always performed.

10737 values, check that the warning is issued.
10739 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
10741 * NEWS: Improve wording for unused-value warnings.
10743 2005-12-22 Akim Demaille <akim@epita.fr>
10745 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4

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

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.
10804 2005-12-21 Joel E. Denny <address@hidden>
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.

10820 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
10821 `if (YYID (N))' to pacify lint.
10823 2005-12-21 Akim Demaille <akim@epita.fr>
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.

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

10876 * tests/sets.at (Accept): Fix typos in regular expression used to
10877 sed out the final state number.
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".

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).

10957 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
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.

11230 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

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

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.
11472 * doc/bison.texinfo (Error Reporting, Table of Symbols):
11473 yynerrs is the number of errors reported, not the number of
11474 errors encountered.
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.
11482 2005-09-19 Akim Demaille <akim@epita.fr>
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.
11491 2005-09-19 Akim Demaille <akim@epita.fr>
11493 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
11494 least Mac OSX with a /usr/local install of gettext.
11496 2005-09-19 Akim Demaille <akim@epita.fr>
11498 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
11499 and yytoken for similarity with the other skeletons.
11501 2005-09-19 Akim Demaille <akim@epita.fr>
11503 * NEWS, configure.ac: update version number to 2.1a.
11505 2005-09-16 Paul Eggert <eggert@cs.ucla.edu>
11507 * NEWS: Version 2.1.
11509 * NEWS: Remove notice of yytname change, since it was never in an
11511 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
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.
11523 2005-09-16 Akim Demaille <akim@epita.fr>
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.
11530 2005-09-16 Akim Demaille <akim@epita.fr>
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
11541 2005-09-16 Akim Demaille <akim@epita.fr>
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.
11552 2005-09-16 Akim Demaille <akim@epita.fr>
11554 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
11555 since it's in Bison's name space.
11557 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
11559 * data/glr.c (yyresolveValue): Add default case to pacify
11560 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
11562 * NEWS: Document when yyparse started to return 2.
11563 * doc/bison.texinfo (Parser Function): Document when yyparse
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
11569 (class position): file_name -> filename (reverting). All uses changed.
11571 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
11573 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
11574 do anything if $@ exists. This reverts part of the 2005-07-07
11577 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
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
11588 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
11590 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
11591 Suggested by twlevo@xs4all.nl.
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.
11597 * doc/bison.texinfo: Don't use "filename", as per GNU coding
11598 standards. Use "file name" or "file" or "name", depending on
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.
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.
11615 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
11617 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
11618 to accommodate latest gnulib.
11620 * tests/glr-regression.at (Duplicate representation of merged trees):
11621 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
11623 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
11626 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
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).
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
11637 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
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.
11643 * bootstrap (no_cache): New var, to accommodate different wget
11644 variants. Use it instead of '-C off'. Problem reported by
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.
11651 2005-08-25 Akim Demaille <akim@epita.fr>
11653 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
11655 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
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
11664 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
11666 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
11668 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
11669 lib-prefix.m4, po.m4.
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.
11679 * src/files.c: Remove obsolete FIXME comment.
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.
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>
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.
11698 * configure.ac (AC_INIT): Bump to 2.0c.
11700 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
11702 * NEWS: Version 2.0b.
11704 * Makefile.am (SUBDIRS): Put examples before tests, so that
11705 "make check" doesn't finish with "All 1 tests passed".
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.
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.
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
11724 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
11725 the user's name space. All uses changed to __attribute__
11727 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
11728 Add __attribute__ ((__noreturn__)).
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.
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.
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.
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.
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.
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.
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):
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.
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".
11807 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
11810 * tests/torture.at: Revamp to avoid misuse of atoi that
11811 "make maintainer-distcheck" complained about.
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.
11817 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
11819 * configure.ac: Update version number.
11821 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
11823 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
11824 autogenerated by the maintainer.
11825 * examples/calc++/.cvsignore: Add *.yy.
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.
11831 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
11833 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
11834 from maintainer-distcheck about casting the argument of 'free'.
11836 * NEWS: Mention recent yytname changes.
11837 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
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
11845 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
11846 now that token names are already quoted.
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.
11856 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
11858 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
11859 again if the first call fails.
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.
11877 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
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
11884 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
11885 as the stack isn't valid in that case.
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
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):
11897 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
11898 overly-picky compilers that reject 'char *foo = "bar";'.
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.
11904 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
11905 warnings from GCC 4.
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.
11912 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
11914 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
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.
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
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".
11951 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
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.
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
11963 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
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
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
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.
11992 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
11993 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
11995 * tests/glr-regression.at (Badly Collapsed GLR States):
11997 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11998 yylex should return 0 at EOF rather than aborting.
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.
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
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).
12020 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
12037 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
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.
12057 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12059 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
12060 a valgrind failure. Problem reported by twlevo@xs4all.nl.
12062 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
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.
12069 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
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
12098 * src/main.c (main): Bind the bison-runtime domain, too.
12100 2005-07-12 Bruno Haible <bruno@clisp.org>
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.
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.

12130 (Internationalization): New section.
12132 2005-07-12 Akim Demaille <akim@epita.fr>
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.
12139 2005-07-12 Akim Demaille <akim@epita.fr>
12141 * src/parse-gram.y: Use %printer instead of YYPRINT.
12143 2005-07-12 Akim Demaille <akim@epita.fr>
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.
12149 2005-07-12 Akim Demaille <akim@epita.fr>
12151 * data/glr.c (b4_syncline): Fix (swap) the definitions of
12152 b4_at_dollar and b4_dollar_dollar.
12154 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
12156 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
12157 and Pennello's paper.
12159 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
12170 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
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
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
12190 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
12192 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
12193 implied by the other modules.
12195 2005-07-06 Akim Demaille <akim@epita.fr>
12197 Bind examples/calc++ to the package.
12198 * examples/calc++/Makefile: Remove, replaced by...

12200 * examples/calc++/test: Remove input.
12201 * examples/calc++/compile: Remove.

12206 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
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.
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
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
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
12245 2005-07-05 Akim Demaille <akim@epita.fr>
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.
12253 2005-06-24 Akim Demaille <akim@epita.fr>
12255 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
12258 2005-06-22 Akim Demaille <akim@epita.fr>
12260 * doc/bison.texinfo (C++ Language Interface): First stab.
12261 (C++ Parsers): Remove.
12263 2005-06-22 Akim Demaille <akim@epita.fr>
12265 * data/lalr1.cc (yylex_): Honor %lex-param.
12267 2005-06-22 Akim Demaille <akim@epita.fr>
12269 Start a set of simple examples.
12270 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
12271 * examples/calc++/calc++-driver.hh,
12272 * examples/calc++/calc++-parser.yy,
12273 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
12274 * examples/calc++/compile, examples/calc++/test: New.
12276 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
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.
12282 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
12284 * data/glr.c: Modify treatment of unused parameters to permit use
12285 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
12287 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
12289 Fix infringement on user name space reported by Janos Zoltan Szabo.
12290 * data/yacc.c (yyparse): strlen -> yystrlen.
12292 2005-05-30 Akim Demaille <akim@epita.fr>
12294 * data/lalr1.cc (_): New.
12295 Translate the various messages.
12297 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
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.
12308 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
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
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.
12318 2005-05-24 Bruno Haible <bruno@clisp.org>
12320 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
12321 error message syntax used by gcc-4.0.
12323 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
12325 * README: Mention m4 1.4.3. Remove obsolete advice about
12326 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
12328 * bootstrap: Remove workaround for problem I encountered with
12329 gettext 0.14.1; it seems to be fixed now.
12331 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
12333 * NEWS: Version 2.0a.
12335 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
12336 the previous change.
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
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):
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.
12360 * bootstrap: Add stdio-safer, unistd-safer modules.
12361 Remove m4/glibc2.m4 (introduced by latest gnulib, but
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.
12372 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
12373 yesterday's yacc.c fix.
12375 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
12377 * data/glr.c, data/lalr1.cc: Update copyright date.
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
12389 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
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.
12396 (struct yyGLRState): Add some comments.
12397 (struct yySemanticOption): Add some comments.
12398 (union yyGLRStackItem): Add comment.
12400 (yymergeOptionSets): Correct this to properly perform the union,
12401 avoiding infinite reported by Michael Rosien.
12404 * tests/glr-regression.at: Add test for GLR merging error reported

12445 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
12447 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
12448 Problem reported by Ralf Menzel.
12450 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
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
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.
12461 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
12463 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
12465 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
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
12473 * tests/input.at (Torturing the Scanner): Likewise.
12474 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
12476 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
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.
12482 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
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
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
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.
12504 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12506 * NEWS: Bison-generated C parsers now use the _ macro to
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.
12514 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
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.
12522 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
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.
12529 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
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.
12536 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
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.
12541 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
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.
12547 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
12549 Respond to problems reported by twlevo@xs4all.nl.
12551 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
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.
12557 * data/yacc.c (yyparse): Omit spaces before #line.
12559 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
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
12565 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
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>.
12575 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
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.
12582 * src/vcg.c (output_edge): Don't quote linestyle arg.
12583 Problem reported by twlevo@xs4all.nl.
12585 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
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.
12591 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
12593 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
12594 putsym. Typo reported by Sebastian Piping.
12596 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12598 * doc/bison.texinfo (Language and Grammar): some -> same
12599 (Epilogue): int he -> in the
12600 Typos reported by Sebastian Piping via Justin Pence.
12602 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
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.
12611 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12613 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
12614 wants to redefine G_VIEW.
12616 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
12618 * src/vcg.c (get_view_str): Remove case for normal_view.
12619 Problem reported by twlevo@xs4all.nl.
12621 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
12623 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
12624 Problem reported by twlevo@xs4all.nl.
12626 * doc/bison.texinfo: Change @dircategory from "GNU programming
12627 tools" to "Software development". Requested by Richard Stallman
12630 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
12632 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
12633 Problem reported by twlevo@xs4all.nl.
12635 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
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
12642 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
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.
12649 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
12651 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
12652 already. Let config.h define any nonstandard values.
12654 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
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.
12660 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
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)".
12667 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
12669 * TODO: Mention that we should allow NUL bytes in tokens.
12671 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
12673 * src/scan-skel.l (<<EOF>>): Don't close standard output.
12674 Problem reported by Hans Aberg.
12676 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
12678 * src/getargs.c (version): Happy new year; update overall
12679 program copyright date from 2004 to 2005.
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
12687 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
12689 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
12690 to fix an oversight in the Bison 2.0 manual.
12692 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
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.
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.
12704 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
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.
12711 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
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
12728 * doc/bison.texinfo (Location Default Action): Mention that n must
12729 be zero when k is zero. Suggested by Frank Heckenbach.
12731 2004-12-22 Akim Demaille <akim@epita.fr>
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.
12748 2004-12-21 Akim Demaille <akim@epita.fr>
12750 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
12752 2004-12-21 Akim Demaille <akim@epita.fr>
12754 Don't impose std::string for filenames.
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
12761 Forward declare them before the user code.
12762 * tests/Makefile.am (check-local, installcheck-local): Pass
12763 TESTSUITEFLAGS to the TESTSUITE.
12765 2004-12-20 Akim Demaille <akim@epita.fr>
12767 Use more STL like names: my_class instead of MyClass.
12769 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
12770 (SemanticStack, SemanticType, StateStack, StateType)
12771 (TokenNumberType, Stack, Slice, Traits, Parser::location)

12774 (semantic_type, state_stack, state_type, token_number_type, stack)
12775 (slice, traits, parser::yylloc, parser::yylval): these.
12777 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
12779 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
12781 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
12782 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12784 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
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.
12790 This change does not affect the generated parsers; that's a different
12791 task, as some users will want to conserve memory there.
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.
12798 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
12799 Use size_t, not int or short int, to count objects.

12819 2004-12-17 Akim Demaille <akim@epita.fr>
12821 * data/lalr1.cc: Extensive Doxygenation.
12822 (error_): Rename as...
12823 (error): this, since it is visible to the user.
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
12829 * tests/input.at: Escape $.

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.

12841 2004-12-16 Akim Demaille <akim@epita.fr>
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.
12847 2004-12-16 Akim Demaille <akim@epita.fr>
12849 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
12852 2004-12-16 Akim Demaille <akim@epita.fr>
12854 Use #define to handle the %name-prefix.
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.
12861 2004-12-16 Akim Demaille <akim@epita.fr>

12883 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
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.

12902 (report_syntax_error_, translate_): Rename as...
12903 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
12904 (yypop_, yyreport_syntax_error_, yytranslate_): this.
12906 2004-12-15 Akim Demaille <akim@epita.fr>
12908 * data/lalr1.cc (lex_): Rename as...
12910 Move the trace here.
12911 Take the %name-prefix into account.
12912 Reported by Alexandre Duret-Lutz.
12914 2004-12-15 Akim Demaille <akim@epita.fr>
12916 Simplify the C++ parser constructor.
12918 * data/lalr1.cc (debug_): Rename as...
12919 (yydebug_): so that the parser's internals are always in the yy*
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.
12929 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
12932 2004-12-15 Akim Demaille <akim@epita.fr>
12934 Remove b4_root related material: failure experiment
12935 (which goal was to allow to derive from a class).
12937 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
12938 definitions and uses.
12940 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
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.
12946 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
12947 the default definition of YYLLOC_DEFAULT. Problem reported
12948 by Frank Heckenbach.
12950 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
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.
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
12967 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
12969 * HACKING: Update email addresses to send announcements to.
12971 * configure.ac (AC_INIT): Bump version to 1.875f.
12973 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
12975 * NEWS: Version 1.875e.
12976 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
12978 * src/scan-skel.l: Include "complain.h", for "fatal".
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,
12985 * src/relation.c: Likewise.
12986 (top, infinity): Now of type relation_node, not int.
12987 (traverse, relation_transpose): Use relation_node, not int.
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.
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.
12998 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
13000 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
13001 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
13002 unless otherwise specified below.
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.

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,
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.
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.
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.

13038 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
13039 conflrow, conflict_table, conflict_list, table, check):
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.
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]
13052 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
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.
13057 * src/table.c (table_grow): When conflict_table grew, the grown
13058 area wasn't cleared. Fix this.
13060 * lib/.cvsignore: Add strdup.c, strdup.h.
13061 * m4/.cvsignore: Add strdup.m4.
13063 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
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.
13074 2004-11-23 Akim Demaille <akim@epita.fr>
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.
13081 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
13083 * bootstrap (gnulib_modules): Add extensions.
13084 Problem reported by Jim Meyering.
13086 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
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.
13094 2004-11-17 Akim Demaille <akim@epita.fr>
13096 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
13098 2004-11-17 Akim Demaille <akim@epita.fr>,
13099 Alexandre Duret-Lutz <adl@gnu.org>
13101 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
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
13108 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
13111 2004-11-17 Akim Demaille <akim@epita.fr>
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.
13118 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
13120 * data/glr.c (yyloc_default): Remove; not used.
13121 Problem reported by Frank Heckenbach.
13123 2004-10-25 Akim Demaille <akim@epita.fr>
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
13140 2004-10-22 Akim Demaille <akim@epita.fr>
13141 and Paul Eggert <eggert@cs.ucla.edu>
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.
13155 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
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>.
13161 2004-10-11 Akim Demaille <akim@epita.fr>
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
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
13176 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
13177 * tests/input.at (Incompatible Aliases): New.
13179 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
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".
13187 2004-10-06 Akim Demaille <akim@epita.fr>
13189 * src/parse-gram.y (add_param): Fix the truncation of trailing
13192 2004-10-05 Akim Demaille <akim@epita.fr>
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.
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
13204 Adjust uses to make sure the code is triggered on empty
13206 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
13207 expected output: empty reductions have empty locations.
13209 2004-09-29 Akim Demaille <akim@epita.fr>
13211 * data/lalr1.cc: Move towards a more standard C++ coding style
13212 for templates: Class < T > -> Class<T>.
13214 2004-09-29 Akim Demaille <akim@epita.fr>
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 ->
13221 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
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.
13226 2004-09-27 Akim Demaille <akim@epita.fr>
13228 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
13230 2004-09-27 Akim Demaille <akim@epita.fr>
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.
13237 2004-09-24 Akim Demaille <akim@epita.fr>
13239 * src/parse-gram.y (add_param): Strip the leading and trailing
13240 blanks from a formal argument declaration.
13241 (YY_LOCATION_PRINT): New.
13243 2004-09-24 Akim Demaille <akim@epita.fr>
13245 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
13246 after the location.
13248 2004-09-24 Akim Demaille <akim@epita.fr>
13250 * doc/bison.texinfo (Table of Symbols): Sort.
13252 2004-09-21 Akim Demaille <akim@epita.fr>
13254 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
13255 the useless parentheses.
13256 Suggested by Paul Eggert.
13258 2004-09-20 Akim Demaille <akim@epita.fr>
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.
13264 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
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
13274 Push them in the stacks.
13275 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
13277 2004-09-20 Akim Demaille <akim@epita.fr>
13279 * doc/bison.texinfo (Initial Action Decl): New.
13281 2004-09-20 Akim Demaille <akim@epita.fr>
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
13288 yylloc is not always available.
13289 * data/glr.c: Likewise.
13290 Also, honor initial-actions.
13292 2004-09-20 Akim Demaille <akim@epita.fr>
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.
13314 * src/scan-skel.l: Instead of abort, report error messages to ease
13315 understanding skeleton scanning failures.
13317 2004-09-16 Akim Demaille <akim@epita.fr>
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
13325 We should probably use vector here though.
13327 2004-09-16 Akim Demaille <akim@epita.fr>
13329 Have more complete shift traces.
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.
13342 2004-09-08 Akim Demaille <akim@epita.fr>
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
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.
13368 2004-09-06 Akim Demaille <akim@epita.fr>
13370 * data/lalr1.cc: Adjust the indentation of the labels.
13371 (Parser::pop): New.
13374 2004-09-06 Akim Demaille <akim@epita.fr>
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
13385 2004-09-03 Akim Demaille <akim@epita.fr>
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.
13394 2004-09-02 Akim Demaille <akim@epita.fr>
13396 * data/lalr1.cc (translate_, destruct_): No reason to be static.
13398 2004-09-02 Akim Demaille <akim@epita.fr>
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
13405 Use it instead of direct symprint_ calls.
13406 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
13409 2004-09-02 Akim Demaille <akim@epita.fr>
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
13415 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
13416 %printer calls to use cdebug_ when using lalr1.cc.
13418 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
13420 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
13421 with #ifdef YYDEBUG.
13423 2004-08-26 Akim Demaille <akim@epita.fr>
13425 * doc/bison.texinfo (Implementing Loops): Rename as...
13426 (Implementing Gotos/Loops): this.
13428 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
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.
13439 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
13441 * src/scan-action.l: Remove. Scanning of semantic actions is
13442 handled in scan-gram.l.
13444 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
13446 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
13448 * src/location.h (struct): The file member is a uniqstr.
13449 (equal_boundaries): Use UNIQSTR_EQ for comparison.
13451 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
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>.
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.
13470 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
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
13477 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
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.
13484 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
13486 * doc/bison.texinfo (Simple GLR Parsers): New section.
13488 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
13490 * NEWS, TODO, doc/bison.texinfo:

13540 C++ compiler. (trivial change)
13542 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
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
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

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>.
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).
13564 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
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.
13570 * doc/bison.texinfo (Decl Summary): Also mention that %union
13571 can depend on prerequisite types. Problem reported by Tim
13574 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13576 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
13577 * README-alpha: Don't tell people not to package this.
13579 * bootstrap: Don't assume $(...) works; use `...` instead.
13580 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
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.
13587 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13589 Undo change made earlier today: it caused autopoint to not bring
13590 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
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.
13598 The gettext version checking is causing more trouble than it's
13599 curing; remove it. Problem reported by Paul Hilfinger.
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.
13605 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
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

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>.
13624 * configure.ac (AC_INIT): Update to 1.875e.

13628 * NEWS: Version 1.875d.
13629 * configure.ac (AC_INIT): Likewise.
13630 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
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.
13639 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
13641 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

13654 (unexpected_end): New function.
13655 (unexpected_eof): Use it.
13656 (unexpected_newline): New function.

13660 * NEWS: Document %expect-rr.
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.
13667 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
13668 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.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,

13674 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
13675 * src/.cvsignore: Add *.output.
13677 * src/parse-gram.y: Put copyright notice inside %{ %} so it
13678 gets copied to the output file.
13680 2004-04-28 Paul Eggert <eggert@twinsun.com>
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
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.
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
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
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.

13722 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
13724 * src/files.c: Include gnulib's xstrndup.h.
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>.

13753 Remove, as these files are now generated automatically
13754 by bootstrap or automake.
13756 * po/ChangeLog: Remove: all but one entry was a duplicate
13757 of this file, and I moved that 2000-11-02 entry here.
13759 * config/.cvsignore: Add Makefile, depcomp, install-sh.
13760 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

13780 support it. (The latest stable gzip doesn't.)
13782 2004-04-27 Paul Eggert <eggert@twinsun.com>
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
13788 Remove more K&R C support.
13789 * lib/libiberty.y (PARAMS): Remove. All uses removed.

13800 unconditionally. Do not declare perror.
13801 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
13804 * src/complain.c (_): Remove useless defn, as system.h defines this.
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.
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.
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.
13822 * tests/synclines.at (%union synch line): Put a dummy member in
13823 the union, because empty unions aren't allowed in C. Caught
13826 2004-04-13 Jim Meyering <jim@meyering.net>
13828 * src/conflicts.c (conflicts_print): Correct format string typo:

13887 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
13889 Use expected_sr_conflicts in place of expected_conflicts.
13890 Warn if expected_rr_conflicts used in non-GLR parser.
13892 * doc/bison.texinfo: Add documentation for %expect-rr.
13894 2004-03-08 Paul Eggert <eggert@gnu.org>
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>.
13899 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
13901 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
13902 * src/scan-gram.l (scan_integer): New function.
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.
13909 2004-02-25 Paul Eggert <eggert@twinsun.com>
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>.
13916 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
13918 Support %destructor and merge error locations in lalr1.cc.
13920 * data/lalr1.cc (b4_cxx_destruct_def): New macro.

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.
13934 2004-02-02 Paul Eggert <eggert@twinsun.com>
13936 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
13937 $(top_srcdir)/lib and ../lib. This fixes a bug reported
13938 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
13939 There's no need to mention top_builddir since Automake does that
13941 (INCLUDES): Remove, as Automake says it's obsolescent.
13942 Contents migrated into AM_CPPFLAGS as described above.
13943 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
13945 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
13947 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
13948 (yyreportSyntaxError): Handle case where lookahead token is
13951 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13953 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
13954 resulting parsers are compilable with C++.
13956 2003-12-23 Paul Eggert <eggert@twinsun.com>
13958 * config/depcomp, config/install-sh: Sync with Automake 1.8.
13959 * src/output.c (output_skeleton): Rename local var.
13960 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
13961 Bison tokens, as this runs afoul of the 2003-10-07 change that
13962 disallowed NUL bytes in character constants or string literals.
13964 * tests/local.at: Require Autoconf 2.59's Autotest.
13965 * tests/testsuite.at: Don't include local.at, since we now assume
13966 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
13968 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
13969 multiple inclusion warnings.

13983 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
13984 if testsuite doesn't exist.
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.
13991 2003-10-05 Paul Eggert <eggert@twinsun.com>
13993 * NEWS: Don't document %no-default-prec, as it's still
13995 * doc/bison.texinfo: Document %no-default-prec only if
13996 the defaultprec flag is set. Normally it's not.
13998 2003-10-04 Paul Eggert <eggert@twinsun.com>
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.

14008 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

14018 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
14019 * src/print_graph.c (print_graph): Adjust.
14021 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
14022 and Paul Eggert <eggert@twinsun.com>
14024 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
14025 Table of Symbols): Document %default-prec.

14042 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
14045 2003-08-26 Akim Demaille <akim@epita.fr>
14047 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
14048 "<\#" to avoid magic from Gnus when posting parts of this script.
14050 2003-08-26 Akim Demaille <akim@epita.fr>
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.
14057 2003-08-25 Akim Demaille <akim@epita.fr>
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.
14064 2003-08-25 Akim Demaille <akim@epita.fr>
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.
14072 * src/reader.h, reader.c (epilogue_augment): Remove, replace
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
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.
14083 2003-08-25 Akim Demaille <akim@epita.fr>
14085 * doc/bison.texinfo: Don't promote stdout for error messages.
14087 2003-08-25 Akim Demaille <akim@epita.fr>
14089 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
14090 From Alexandre Duret-Lutz.

14103 * data/lalr1.cc (Parser::reduce_print_): New.
14106 2003-08-25 Akim Demaille <akim@epita.fr>
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.
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
14127 2003-08-25 Akim Demaille <akim@epita.fr>
14129 Tune local.at so that people can "autom4te -l autotest calc.at -o
14130 calc" for instance, to extract a sub test suite.
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
14137 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
14140 2003-08-04 Paul Eggert <eggert@twinsun.com>
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.
14147 2003-07-26 Paul Eggert <eggert@twinsun.com>
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.
14155 2003-07-25 Paul Eggert <eggert@twinsun.com>
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.
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.
14172 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
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>
14179 2003-06-25 Akim Demaille <akim@epita.fr>
14181 * config/depcomp, config/install-sh: Update from masters.
14183 2003-06-20 Paul Eggert <eggert@twinsun.com>
14185 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
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.

14191 conventions for parentheses.
14193 2003-06-19 Paul Eggert <eggert@twinsun.com>
14195 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
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>.
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
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.
14209 2003-06-17 Paul Eggert <eggert@twinsun.com>
14211 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
14212 avoid warnings from picky compilers about redefinition of PARAMS.
14214 2003-06-17 Paul Eggert <eggert@twinsun.com>
14218 * NEWS: Document 1.875b.
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.

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
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.
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.

14263 * m4/.cvsignore: Add nls.m4, po.m4.
14265 Upgrade to CVS gnulib.
14266 * stdbool_.h: File renamed from stdbool.h.in.
14267 * configure.ac (AM_STDBOOL_H): Invoke this instead of
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.

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.
14286 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14288 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
14290 (yyrecoverSyntaxError): Correct the logic for setting and testing
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).
14296 Fixes to avoid problem that $-N rules in GLR parsers can cause
14297 buffer overruns, corrupting state.
14299 * src/output.c (prepare_rules): Output max_left_semantic_context
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.
14308 Fixes to problems with location handling in GLR parsers reported by
14309 Frank Heckenbach (2003/06/05).
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.
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
14329 2003-06-03 Paul Eggert <eggert@twinsun.com>
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,

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.
14346 2003-06-02 Paul Eggert <eggert@twinsun.com>
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.
14352 2003-06-01 Paul Eggert <eggert@twinsun.com>
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.
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.
14373 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
14374 as possibly unused.
14375 (yyfill): New function.
14377 (yyuserAction): Change type of yynormal to bool, so that it matches
14378 the new yyfill signature. Mark it as possibly unused.
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>
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
14405 2003-05-24 Paul Eggert <eggert@twinsun.com>
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.
14415 Switch from 'int' to 'bool' where that makes sense.

14478 2003-05-14 Paul Eggert <eggert@twinsun.com>

14481 semicolon after a grammar declaration, in the interest of possible

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.

14491 %parse-param support for lalr1.cc.

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.
14513 2003-05-05 Paul Eggert <eggert@twinsun.com>
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>.
14520 2003-05-03 Paul Eggert <eggert@twinsun.com>
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>.
14527 2003-04-29 Akim Demaille <akim@epita.fr>
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.
14539 2003-04-29 Akim Demaille <akim@epita.fr>
14541 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
14543 2003-04-29 Akim Demaille <akim@epita.fr>
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
14549 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
14551 * data/yacc.c: (b4_lex_param): Corrected for the case where
14552 %lex-param is provided and %pure-parser isn't.
14554 2003-04-27 Paul Eggert <eggert@twinsun.com>
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>
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>.
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>.
14577 2003-04-21 Paul Eggert <eggert@twinsun.com>
14579 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
14582 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
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)
14588 2003-04-17 Paul Eggert <eggert@twinsun.com>
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.
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>.
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.
14608 * tests/existing.at (GNU pic Grammar): New test case, taken from
14611 2003-03-31 Akim Demaille <akim@epita.fr>
14613 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
14615 2003-03-31 Akim Demaille <akim@epita.fr>
14617 * src/output.c (prepare_symbols): Avoid trailing spaces in the
14620 2003-03-31 Akim Demaille <akim@epita.fr>
14622 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
14623 From Paul Hilfinger.
14625 2003-03-29 Akim Demaille <akim@epita.fr>
14627 * m4/error.m4: Do not put under dynamic conditions some code which
14628 expansion is under static control.
14630 2003-03-29 Akim Demaille <akim@epita.fr>
14632 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
14634 2003-03-29 Akim Demaille <akim@epita.fr>
14636 * doc/bison.texinfo (Strings are Destroyed): New.
14638 2003-03-13 Paul Eggert <eggert@twinsun.com>
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.
14645 2003-03-12 Paul Eggert <eggert@twinsun.com>
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.
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>.
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.
14665 Merge changes from gnulib. This was prompted because the CVS
14666 snapshot didn't build on Solaris 7 due to strnlen problems.
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}
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,
14678 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
14679 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.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
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
14689 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
14691 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
14692 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.

14695 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
14696 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
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.
14702 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
14703 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
14705 * src/system.h: Include <stdbool.h> unconditionally.
14707 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
14708 assuming at least C89 in the bitset code for some time now.
14710 2003-03-03 Akim Demaille <akim@epita.fr>
14714 2003-03-02 Akim Demaille <akim@epita.fr>
14716 * doc/bison.texinfo (Table of Symbols): Reactivate the
14717 documentation for %lex-param, and %parse-param.
14719 2003-03-02 Akim Demaille <akim@epita.fr>
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.
14726 2003-03-02 Akim Demaille <akim@epita.fr>
14728 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
14731 2003-03-02 Akim Demaille <akim@epita.fr>
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.
14737 2003-03-02 Akim Demaille <akim@epita.fr>
14739 Create tests/local.at for Bison generic testing macros.
14741 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
14742 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):

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.
14751 2003-03-01 Paul Eggert <eggert@twinsun.com>
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.
14762 2003-03-01 Akim Demaille <akim@epita.fr>
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.
14769 2003-02-28 Paul Eggert <eggert@twinsun.com>
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>.
14775 2003-02-26 Paul Eggert <eggert@twinsun.com>
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.
14783 2003-02-24 Paul Eggert <eggert@twinsun.com>
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>.
14789 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
14790 * data/yacc.c (yy_reduce_print): Likewise.
14792 * config/depcomp: Sync with Automake 1.7.3.
14794 2003-02-21 Akim Demaille <akim@epita.fr>
14796 * data/lalr1.cc: Use temporary variables instead of casts to
14797 change integer types.
14798 Suggested by Paul Eggert.
14800 2003-02-21 Akim Demaille <akim@epita.fr>
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.
14806 2003-02-20 Akim Demaille <akim@epita.fr>
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
14812 Use "last" so that we subtract from Positions, not from unsigned.
14814 2003-02-20 Akim Demaille <akim@epita.fr>
14816 * data/lalr1.cc (position.hh): New subfile, including the extended
14817 and Doxygen'ed documentation of class Position.
14818 (location.hh): Use it.
14819 Document a` la Doxygen.
14820 With the help of Benoit Perrot.
14822 2003-02-20 Akim Demaille <akim@epita.fr>

14826 Redefine AT_YYERROR_SEES_LOC_IF using it.
14827 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
14829 Don't use the location in yy::Parser::error_ and
14830 yy::Parser::print_ when not %locations.
14831 Activate more lalr1.cc tests.
14833 2003-02-19 Akim Demaille <akim@epita.fr>
14835 * data/lalr1.cc: When displaying a line number, be sure to make it
14838 2003-02-19 Akim Demaille <akim@epita.fr>
14840 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
14842 (YYABORT, YYACCEPT, YYERROR): New.
14843 * tests/calc.at: Renable the lalr1.cc test.
14845 2003-02-19 Akim Demaille <akim@epita.fr>
14847 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
14848 error recovery, mixing with/without pops and discarding of the
14851 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
14853 2003-02-17 Paul Eggert <eggert@twinsun.com>
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>.
14860 2003-02-12 Paul Eggert <eggert@twinsun.com>
14862 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
14863 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

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.
14869 The bug still remains in data/lalr1.cc, as I didn't have time
14872 2003-02-06 Akim Demaille <akim@epita.fr>
14874 * configure.ac (GXX): Rename as...
14875 (CXX): this, to keep the original Autoconf semantics.
14877 * data/lalr1.cc: Fix b4_copyright invocations.

14894 Adjust the C locations to match those from Emacs: first column is
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
14900 these CPP macros with the m4 macros new defined by...
14901 (AT_CHECK_PUSHDEFS): this, i.e.:
14902 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

14905 (AT_CHECK_POPDEFS): Undefine them.
14906 (AT_CHECK_CALC_LALR1_CC): New.

14911 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
14912 Location as is defined.
14914 2003-02-04 Akim Demaille <akim@epita.fr>
14916 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon

14919 2003-02-03 Paul Eggert <eggert@twinsun.com>
14921 * src/gram.h (start_symbol): Remove unused decl.

14961 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
14963 * src/uniqstr.h: Likewise.
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.
14972 2003-02-02 Akim Demaille <akim@epita.fr>
14974 * src/scan-skel.l: Scan more than one inert character per yylex
14977 2003-02-01 Paul Eggert <eggert@twinsun.com>
14981 * po/LINGUAS: Add ms.
14983 2003-01-30 Akim Demaille <akim@epita.fr>
14985 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
14987 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14989 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
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>.
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
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
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
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.
15020 2003-01-28 Paul Eggert <eggert@twinsun.com>
15022 * data/lalr1.cc: Do not use @output_header_name@ unless
15023 b4_defines_flag is set. This fixes two bugs reported by
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>.
15028 2003-01-21 Paul Eggert <eggert@twinsun.com>
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
15036 (yyerrlab1): Move code to YERROR.
15037 (yyerrlab2): Remove. Change uses back to yyerrlab1.
15038 This reverts some of the 2002-12-27 change.
15040 2003-01-17 Paul Eggert <eggert@twinsun.com>
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>.
15046 2003-01-13 Akim Demaille <akim@epita.fr>,
15047 Quoc Peyrot <chojin@lrde.epita.fr>,
15048 Robert Anisko <anisko_r@lrde.epita.fr>
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.
15057 2003-01-11 Paul Eggert <eggert@twinsun.com>
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).
15070 * src/getargs.c (version): Update copyright year.
15072 2003-01-09 Akim Demaille <akim@epita.fr>
15074 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
15076 2003-01-08 Paul Eggert <eggert@twinsun.com>
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.
15083 2003-01-06 Paul Eggert <eggert@twinsun.com>
15085 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
15086 the GLR paper of Scott, Johnstone and Hussain.
15088 2003-01-04 Paul Eggert <eggert@twinsun.com>
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.
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.
15101 2003-01-03 Paul Eggert <eggert@twinsun.com>
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.
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.
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.
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).
15122 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
15123 Reported by Nelson H. F. Beebe.
15125 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
15127 2003-01-02 Paul Eggert <eggert@twinsun.com>
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.
15133 2003-01-01 Paul Eggert <eggert@twinsun.com>
15137 2002-12-30 Paul Eggert <eggert@twinsun.com>
15139 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
15141 (<INITIAL>","): Here. This causes stray "," to be treated
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
15149 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
15150 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
15152 2002-12-28 Paul Eggert <eggert@twinsun.com>
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
15158 2002-12-28 Paul Eggert <eggert@twinsun.com>
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
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.
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.
15186 2002-12-27 Paul Eggert <eggert@twinsun.com>
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>.
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.
15209 2002-12-26 Paul Eggert <eggert@twinsun.com>
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..
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.
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 ".".
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
15234 2002-12-25 Paul Eggert <eggert@twinsun.com>
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".
15242 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
15245 * src/parse-gram.y (declaration): Use enum "report_states" rather
15246 than its numeric value 1.
15248 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
15249 opening a new one. This fixes Debian bug 165349, reported by
15252 2002-12-24 Paul Eggert <eggert@twinsun.com>
15256 * Makefile.maint (cvs-update): Don't assume that the shell
15257 supports $(...), as Solaris sh doesn't.
15259 * src/parse-gram.y (lloc_default): Remove test for empty
15260 nonterminals at the end, since it didn't change the result.
15262 2002-12-24 Paul Eggert <eggert@twinsun.com>
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.
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'.
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.
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.
15288 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
15289 does not specify a union tag. This is for compatibility with
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.
15303 * src/reader.h (braced_code, current_braced_code): Remove.
15304 (token_name): New decl.
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.
15324 * NEWS, doc/bison.texinfo: Document the above.
15325 * NEWS: Fix years and program names in copyright notice.
15327 2002-12-17 Paul Eggert <eggert@twinsun.com>
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.
15333 2002-12-15 Paul Eggert <eggert@twinsun.com>
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.
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
15348 2002-12-13 Paul Eggert <eggert@twinsun.com>
15352 POSIX requires a "yacc" command.
15353 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
15354 (MOSTLYCLEANFILES): Add yacc.
15356 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
15357 as an alias for bison y.
15359 * po/LINGUAS: Add da.
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.
15365 * doc/fdl.texi: Upgrade to 1.2.
15366 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
15367 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
15368 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
15370 * config/install-sh: Sync with autotools.
15372 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
15373 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
15374 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
15375 locations are requested.
15376 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
15377 locations are requested.
15379 2002-12-12 Paul Eggert <eggert@twinsun.com>
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.
15385 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
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.
15393 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
15395 * src/derives.c (derives_compute): Do not bother invoking
15396 int_of_rule_number, since rule numbers are integers.
15398 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
15399 rather than XMALLOC (char, N).
15401 * src/files.c (filename_split): Rewrite to avoid cast.
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.
15411 * src/gram.h (int_of_rule_number): Remove; no longer used.
15413 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
15414 since the resulting storage is always stored into.
15416 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
15419 * src/muscle_tab.c (muscle_m4_output):
15420 Now inline. Return bool, not int.
15421 * src/state.c (state_compare): Likewise.
15422 * src/symtab.c (symbol_check_defined,
15423 symbol_check_alias_consistency, symbol_pack, symbol_translation,

15434 * src/uniqstr.c (uniqstr_print_processor): Likewise.
15435 * src/muscle_tab.c (muscles_m4_output):

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.
15449 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
15450 local var instead of casting to unsigned char, to avoid casts.

15453 STATE_ALLOC): Remove.
15454 (transitions_new, errs_new, reductions_new, state_new): Use malloc

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
15478 * src/tables.c (table_size): Now int, to pacify GCC.

15491 2002-12-09 Paul Eggert <eggert@twinsun.com>
15493 Change identifier spellings to avoid collisions with names
15494 that are reserved by POSIX.
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.
15503 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

15574 value_t_as_yystype -> value_as_yystype.
15576 Don't include <errno.h> in the mainstream code, since it
15577 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
15578 * lib/get-errno.c, lib/get-errno.h: New files.
15579 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

15594 likewise for "STRUNIQ" and "UNIQSTR".
15595 * src/uniqstr.c: Renamed from src/struniq.c.
15596 * src/uniqstr.h: Renamed from src/struniq.h.
15597 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

15607 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.

15619 (BASE_MINIMUM): Renamed from BASE_MIN.
15620 (ACTION_MAX): Remove; unused.
15621 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
15622 Unnecessary casts removed from above defines.
15625 Fix misspelling in names.
15626 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
15627 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
15631 * lib/timevar.c (timevar_report): Renamed from time_report,
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.
15637 Sort include-file uses.
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".
15647 2002-12-08 Paul Eggert <eggert@twinsun.com>
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>.
15656 2002-12-06 Paul Eggert <eggert@twinsun.com>
15658 Add support for rules that do not have trailing semicolons, as
15659 POSIX requires. Improve the quality of locations in Bison
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.
15683 (declarations, rules): Remove trailing semicolon.
15684 (declaration, rules_or_grammar_declaration):

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
15693 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
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,
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.
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.
15737 2002-12-06 Paul Eggert <eggert@twinsun.com>
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.
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.
15747 2002-12-02 Paul Eggert <eggert@twinsun.com>
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
15752 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
15754 2002-11-30 Paul Eggert <eggert@twinsun.com>
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.
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.
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.
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,
15777 2002-11-29 Paul Eggert <eggert@twinsun.com>
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
15786 %parse-param and %lex-param now take just one argument, the
15787 declaration; the argument name is deduced from the declaration.
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.
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.
15798 2002-11-27 Paul Eggert <eggert@twinsun.com>
15800 Rename identifiers to avoid real and potential collisions.
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.
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.
15822 * src/parse-gram.y (gram_error): loc is now const *.
15823 * src/reader.h (gram_error): Likewise.
15825 2002-11-24 Paul Eggert <eggert@twinsun.com>
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.
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.
15840 * lib/error.c: Sync with gnulib.

15852 2002-11-20 Paul Eggert <eggert@twinsun.com>
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.
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.

15893 if the assertion is false.

15897 2002-11-18 Paul Eggert <eggert@twinsun.com>
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>.
15904 2002-11-18 Akim Demaille <akim@epita.fr>
15906 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
15908 From Tim Van Holder.
15910 2002-11-17 Paul Eggert <eggert@twinsun.com>
15912 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
15913 to "SyntaxError" for consistency with my 2002-11-15 change.
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
15920 (yyhasResolvedValue): Remove unused function.
15921 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
15923 (yyreportSyntaxError): Renamed from yyreportParseError.
15924 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
15926 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
15927 extern when possible. Remove unused initializations.
15929 2002-11-16 Akim Demaille <akim@epita.fr>
15931 Augment the similarity between GLR and LALR traces.
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
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.
15942 2002-11-16 Akim Demaille <akim@epita.fr>
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.
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'.
15957 2002-11-16 Akim Demaille <akim@epita.fr>
15959 Make the ``Printers and Destructors'' test more verbose, taking
15960 `yacc.c''s behavior as (possibly wrong) reference.
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.
15967 2002-11-16 Paul Eggert <eggert@twinsun.com>
15969 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
15971 2002-11-15 Paul Eggert <eggert@twinsun.com>
15973 * tests/actions.at (Actions after errors): New test case.
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.
15983 2002-11-15 Akim Demaille <akim@epita.fr>
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.
15993 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
15995 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
15996 definition; avoids potential autoreconf problems.
15998 2002-11-15 Akim Demaille <akim@epita.fr>
16000 Always check the value returned by yyparse.
16002 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
16003 returned by yyparse.

16014 2002-11-14 Paul Eggert <eggert@twinsun.com>
16016 * src/output.c (output_skeleton): Call xfopen instead of
16017 duplicating xfopen's body.
16019 Fix bugs reported by Nelson H. F. Beebe in
16020 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
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.
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.
16033 2002-11-14 Akim Demaille <akim@epita.fr>
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.
16040 2002-11-14 Akim Demaille <akim@epita.fr>
16042 * tests/atlocal.in (CPPFLAGS): We have config.h.

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'.
16053 2002-11-14 Akim Demaille <akim@epita.fr>
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.
16060 2002-11-13 Paul Eggert <eggert@twinsun.com>
16062 Fix some bugs reported by Albert Chin-A-Young in
16063 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
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.
16070 * tests/input.at (Torturing the Scanner): Remove lines containing
16071 solitary backslashes, as they tickle a bug in the HP C compiler.
16073 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
16074 comments, since they're not portable. Use GNU coding style.
16076 2002-11-13 Akim Demaille <akim@epita.fr>
16078 * data/yacc.c: Leave bigger chunks of quoted text.
16079 (YYDSYMPRINTF): New.
16080 Use it to report symbol activities.

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>.
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.
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>.
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
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.
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.
16119 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
16121 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
16122 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
16125 2002-11-12 Akim Demaille <akim@epita.fr>
16127 * Makefile.maint: Sync with Autoconf:
16128 (local_updates): New.

16144 2002-11-12 Akim Demaille <akim@epita.fr>
16146 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
16147 Use it to test the GLR parser.
16149 2002-11-12 Akim Demaille <akim@epita.fr>
16151 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
16153 * data/glr.c (yystos): New.
16154 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
16155 (YYDSYMPRINT): New.
16156 (yyval): Don't define it, it is handled via M4.
16157 (yyrecoverParseError): Free verbosely the discarded symbols.
16158 * data/yacc.c (yysymprint): Remove, rather...
16159 (b4_yysymprint_generate): invoke.
16160 * data/c.m4 (b4_yysymprint_generate): New.
16161 Accept pointers as arguments, as opposed to the version from
16163 (b4_yydestruct_generate): Likewise.
16164 * tests/cations.at (Printers and Destructors): Use Bison directives
16165 instead of CPP macros.
16166 Don't rely on internal details.
16168 2002-11-12 Akim Demaille <akim@epita.fr>
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
16178 for 0, end-of-input.
16180 2002-11-12 Akim Demaille <akim@epita.fr>
16182 * doc/bison.texinfo (Destructor Decl): New.
16184 2002-11-12 Akim Demaille <akim@epita.fr>
16186 * src/tables.c (tables_generate): Use free for pointers that
16187 cannot be NULL, not XFREE.
16188 (pack_vector): Use assert, not fatal, for bound violations.
16189 * src/state.c (state_new): Likewise.

16195 2002-11-12 Akim Demaille <akim@epita.fr>
16197 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
16199 * src/scan-gram.l (last_string): Is global to the file, not to

16204 (epilogue_augment): this.
16205 * data/c.m4 (b4_epilogue): Defaults to empty.

16263 2002-11-11 Paul Eggert <eggert@twinsun.com>
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>
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.
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.
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
16287 * data/lalr1.cc: Likewise.
16288 * data/yacc.c: Likewise.
16290 * src/files.c (output_infix): Remove; all uses removed.
16291 * src/files.h: Likewise.
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
16296 * data/yacc.c: Likewise.
16297 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
16299 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
16300 * data/yacc.c: Likewise.
16302 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
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.
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.
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 ].
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.
16330 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
16331 __oline__, #output, $@, and @{ do not have unintended meanings.
16333 2002-11-09 Paul Eggert <eggert@twinsun.com>
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
16340 (yygetLRActions, yyrecoverParseError): Use them.
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.
16347 * tests/regression.at (Invalid inputs): Adjust wording in
16348 diagnostic to match the new behavior.
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
16357 2002-11-07 Paul Eggert <eggert@twinsun.com>
16359 * src/parse-gram.y (CHARACTER): Remove unused token.
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.
16366 Remove nounput option. At an unexpected end of file, we now unput
16367 the minimal input necessary to end cleanly; this simplifies the
16370 Avoid unbounded token sizes where this is easy.
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.

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.
16381 2002-11-07 Akim Demaille <akim@epita.fr>
16383 Let yyerror always receive the msg as last argument, so that
16384 yyerror can be variadic.
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.

16394 2002-11-06 Akim Demaille <akim@epita.fr>
16396 #line should have quoted strings.
16397 Ideally, this should be done by m4_quotearg.

16401 * src/output.c (symbol_printers_output)
16402 (symbol_destructors_output): Quote the file name.

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.
16421 2002-11-06 Akim Demaille <akim@epita.fr>
16423 * src/main.c (main): Free `infile'.

16426 * src/output.c (user_actions_output, symbol_destructors_output)
16427 (symbol_printers_output): Use the location's file name, not

16431 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16433 * src/tables.c (matching_state): Don't allow states to match if
16434 either has GLR conflict entries.
16436 2002-11-05 Paul Eggert <eggert@twinsun.com>
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
16443 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
16444 Also, remove one static variable in the scanner.
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.
16454 2002-11-05 Akim Demaille <akim@epita.fr>
16456 * src/scan-gram.l: When it starts with `%', complain about the
16457 whole directive, not just that `invalid character: %'.
16459 2002-11-04 Akim Demaille <akim@epita.fr>
16461 * Makefile.maint: Update from Autoconf.
16462 (update, cvs-update, po-update, do-po-update): New.
16464 2002-11-04 Akim Demaille <akim@epita.fr>
16466 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
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.
16473 2002-11-04 Akim Demaille <akim@epita.fr>
16475 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
16477 * src/scan-gram.l: Use [\'] instead of ['] to pacify
16480 Use quote, not quote_n since LOCATION_PRINT no longer uses the
16483 2002-11-03 Paul Eggert <eggert@twinsun.com>
16485 * src/reader.c (get_merge_function, grammar_current_rule_check):
16486 Use consistent diagnostics for reporting type name clashes.
16487 Quote the types with <>, for consistency with Yacc.
16488 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
16490 2002-11-03 Akim Demaille <akim@epita.fr>
16492 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
16494 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
16495 (b4_parse_param): Remove.
16496 Use b4_identification.
16497 Propagate b4_pure_args where needed to pass them to yyerror.
16498 * data/glr.m4 (b4_parse_param): Remove.
16499 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

16502 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
16503 b4_user_formals and b4_user_args.
16504 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
16505 (yyreportAmbiguity): When using a pure parser, also need
16506 the location, and the parse-params.
16508 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
16509 When using a pure parser, also need the parse-params.
16511 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
16512 (%pure-parser + %parse-param) LALR and GLR parsers.
16513 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
16514 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
16515 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
16516 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

16518 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
16519 * doc/bison.texinfo: Untabify the whole file.
16520 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
16521 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
16522 (Error Reporting): Adjust to these new directives.
16523 Document %error-verbose, deprecate YYERROR_VERBOSE.
16525 2002-11-03 Akim Demaille <akim@epita.fr>
16527 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
16528 AT_CHECK_CALC_GLR invocations to use % directives, instead of
16529 command line options.
16530 * tests/cxx-type.at: Formatting changes.
16532 2002-11-03 Paul Eggert <eggert@twinsun.com>
16534 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
16535 to count columns correctly, and to check for invalid inputs.
16537 Use mbsnwidth to count columns correctly. Account for tabs, too.
16538 Include mbswidth.h.
16539 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
16540 (extend_location): New function.
16541 (YY_LINES): Remove.
16543 Handle CRLF in C code rather than in Lex code.
16544 (YY_INPUT): New macro.
16545 (no_cr_read): New function.
16547 Scan UCNs, even though we don't fully handle them yet.
16548 (convert_ucn_to_byte): New function.
16550 Handle backslash-newline correctly in C code.
16551 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
16552 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
16554 (tag, splice): New EREs. Do not allow NUL or newline in tags.
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).
16559 (letter, id): Don't assume ASCII; e.g., spell out a-z.
16561 ({int}, handle_action_dollar, handle_action_at): Check for integer
16564 (YY_STEP): Omit trailing semicolon, so that it's more like C.
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.
16572 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
16573 with quote slot used by complain_at.
16575 * tests/input.at: Add tests for backslash-newline, m4 quotes
16576 in symbols, long literals, and funny escapes in strings.
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.
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.
16589 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
16592 2002-11-02 Paul Eggert <eggert@twinsun.com>
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.
16598 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
16599 bug in trigraph handling.
16601 * src/output.c (prepare_symbols): When printing token names,
16602 escape "[" as "@<:@" and likewise for "]".
16604 * src/system.h (errno): Remove declaration, as we are now
16605 assuming C89 or better, and C89 guarantees errno.
16607 2002-10-30 Paul Eggert <eggert@twinsun.com>
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
16613 * src/files.c (xfclose): Likewise. Report I/O error if ferror
16615 * src/output.c (output_skeleton): Use xfclose rather than fclose
16616 and ferror. xfclose now checks ferror.
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.
16622 2002-10-30 Akim Demaille <akim@epita.fr>
16624 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
16627 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
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.

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.
16643 2002-10-24 Akim Demaille <akim@epita.fr>
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
16650 2002-10-24 Akim Demaille <akim@epita.fr>
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.
16659 2002-10-23 Paul Eggert <eggert@twinsun.com>
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.
16667 2002-10-22 Akim Demaille <akim@epita.fr>
16669 * src/system.h: Include sys/types.
16670 Reported by Bert Deknuydt.
16672 2002-10-23 Paul Eggert <eggert@twinsun.com>
16674 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
16675 Suggested by Art Haas.
16677 2002-10-22 Paul Eggert <eggert@twinsun.com>
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.
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
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.
16695 2002-10-22 Akim Demaille <akim@epita.fr>
16697 * data/README: New.
16699 2002-10-21 Paul Eggert <eggert@twinsun.com>
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.
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.
16716 * src/main.c (main): Use exit to exit with failure.
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.
16724 * src/getarg.c (getargs): Remove duplicate code for
16725 "Try `bison --help'".
16727 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
16728 What was that "2" for?
16730 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
16731 * src/getargs.c (usage): Likewise.
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.
16737 2002-10-20 Paul Eggert <eggert@twinsun.com>
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.
16752 2002-10-20 Akim Demaille <akim@epita.fr>
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.
16762 2002-10-20 Akim Demaille <akim@epita.fr>
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
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.
16776 2002-10-20 Akim Demaille <akim@epita.fr>
16778 * src/output.c (prepare): Move the definition of `tokens_number',
16779 `nterms_number', `undef_token_number', `user_token_number_max'
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 `<'.
16791 2002-10-20 Akim Demaille <akim@epita.fr>
16793 * src/tables.h, src/tables.c, src/output.c: Comment changes.
16795 2002-10-20 Akim Demaille <akim@epita.fr>
16797 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
16800 2002-10-20 Akim Demaille <akim@epita.fr>
16802 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.

16808 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
16811 2002-10-19 Paul Eggert <eggert@twinsun.com>
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.

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.
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.
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.
16843 * src/output.c (prepare): Use xstrdup to convert char const *
16844 to char *, to avoid GCC warning.
16846 2002-10-19 Akim Demaille <akim@epita.fr>
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.
16854 2002-10-19 Akim Demaille <akim@epita.fr>
16856 Prototype support of %lex-param and %parse-param.
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.
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.
16878 2002-10-19 Akim Demaille <akim@epita.fr>
16880 * src/getargs.c (usage): Take status as argument and exit
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 ()'.
16887 2002-10-18 Paul Eggert <eggert@twinsun.com>
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.
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.
16897 2002-10-17 Akim Demaille <akim@epita.fr>
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.
16909 2002-10-16 Paul Eggert <eggert@twinsun.com>
16911 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
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.
16922 2002-10-15 Paul Eggert <eggert@twinsun.com>
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.
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.
16934 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

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_,

17002 2002-10-14 Akim Demaille <akim@epita.fr>
17004 * tests/Makefile.am (maintainer-check-posix): New.
17006 2002-10-14 Akim Demaille <akim@epita.fr>
17008 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
17011 2002-10-14 Akim Demaille <akim@epita.fr>
17013 * src/tables.c (table_ninf_remap): base -> tab.
17014 Reported by Matt Rosing.
17016 2002-10-14 Paul Eggert <eggert@twinsun.com>
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.
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.
17032 2002-10-13 Paul Eggert <eggert@twinsun.com>
17034 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
17035 true due to limited range of data type" warning from GCC.
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.
17041 2002-10-13 Akim Demaille <akim@epita.fr>
17043 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
17044 Un yy- yyrhs to avoid the name clash with the global YYRHS.
17046 2002-10-13 Akim Demaille <akim@epita.fr>
17048 * Makefile.maint: Update from Autoconf 2.54.
17049 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
17051 2002-10-13 Akim Demaille <akim@epita.fr>
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.
17057 2002-10-13 Akim Demaille <akim@epita.fr>
17059 Let nondeterministic skeletons be usable with deterministic
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.
17070 * src/tables.c (pack_table): Always create conflict_table.
17071 (token_actions): Always create conflict_list.
17072 * data/glr.c (YYFLAG): Remove, unused.
17074 2002-10-13 Akim Demaille <akim@epita.fr>
17076 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
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.
17085 2002-10-13 Akim Demaille <akim@epita.fr>
17087 * data/glr.c: Formatting changes.
17088 Tweak some trace messages to match yacc.c's.
17090 2002-10-13 Akim Demaille <akim@epita.fr>
17092 GLR parsers sometimes raise parse errors instead of performing the
17094 Reported by Charles-Henry de Boysson.
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
17100 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
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
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.
17118 2002-10-13 Paul Eggert <eggert@twinsun.com>
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
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.
17131 2002-10-12 Paul Eggert <eggert@twinsun.com>
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>.
17140 * lib/timevar.c: Update copyright date and clarify comments.
17141 (get_time) [IN_GCC]: Keep the GCC version for reference.
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.
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>.
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>.
17159 2002-10-11 Paul Eggert <eggert@twinsun.com>
17161 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
17162 (yyparse): here. This undoes some of the 2002-07-25 change.

17179 Portability fixes for bitsets; this also avoids several GCC
17182 * lib/abitset.c: Include <stddef.h>, for offsetof.
17183 * lib/lbitset.c: Likewise.
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.
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.
17196 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
17197 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,

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,

17221 * lib/ebitset.h: Likewise.
17222 * lib/lbitset.h: Likewise.
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

17228 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17229 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
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,

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):
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
17255 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17257 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17259 * lib/ebitset.c (PFV): Remove.
17260 * lib/lbitset.c (PFV): Likewise.

17270 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
17273 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
17275 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
17276 Use offsetof, for simplicity.
17278 2002-10-06 Paul Eggert <eggert@twinsun.com>
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.
17287 2002-10-04 Paul Eggert <eggert@twinsun.com>

17293 * doc/bison.texinfo: Minor spelling, grammar, and white space
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.

17302 * src/Makefile.am (AM_CFLAGS): Likewise.
17303 (AM_YFLAGS): Renamed from YFLAGS.
17305 Fix some MAX and MIN problems.

17308 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
17309 * src/reader.c (reader): Use it.
17311 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
17312 POSIX 1003.1-2001 has removed fgrep.
17314 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

17587 PROTOTYPES to check for prototypes, and "defined __STDC__" to

17831 parsers now contain `reduce 0' as default reduction.

17882 token_translations instead of `0'.
17883 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
17885 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
17886 for the time being: %locations ought to provide it to yyerror.

17890 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

17905 Handle the `- 1' part in rule numbers from/to item numbers.

19536 * tests/regression.at (Web2c Actions): Adjust.
19538 2002-04-22 Akim Demaille <akim@epita.fr>
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.

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
19548 (256) and undefined (2)).
19550 2002-04-22 Akim Demaille <akim@epita.fr>
19552 Propagate more token_number_t.

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.

19612 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
19613 `user_token_number_max'.

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

19857 2002-04-07 Akim Demaille <akim@epita.fr>
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...
19863 2002-04-07 Akim Demaille <akim@epita.fr>
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.
19869 2002-04-07 Akim Demaille <akim@epita.fr>
19871 * src/closure.c, src/print.c, src/reader.c, src/reduce.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.
19890 2002-04-04 Paul Eggert <eggert@twinsun.com>
19892 * doc/bison.texinfo: Update copyright date.
19893 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

20121 2002-02-28 Akim Demaille <akim@epita.fr>
20123 * data/bison.c++: Copy the prologue of bison.simple to fetch

20126 2002-02-25 Akim Demaille <akim@epita.fr>
20128 * src/getargs.c (version): Give the name of the authors, and use a

20157 2002-02-14 Paul Eggert <eggert@twinsun.com>
20159 Remove the support for C++ namespace cleanliness; it was
20160 causing more problems than it was curing, since it didn't work
20161 properly on some nonstandard C++ compilers. This can wait
20162 for a proper C++ parser.
20164 * NEWS: Document this.
20165 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
20166 of C++, as it's treated like C now.

20180 2002-02-13 Andreas Schwab <schwab@suse.de>
20182 * src/output.c (output_rule_data): Don't output NULL, it might
20183 not be defined yet.
20185 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
20187 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
20188 (Copyright notice): Update.

20204 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
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.
20210 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20212 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
20214 (yy::b4_name::parse): Use print_.
20216 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20218 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
20220 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20222 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
20224 (yy::b4_name::parse): Build verbose error messages, and use error_.
20226 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
20228 * data/bison.c++: Fix m4 quoting in comments.
20230 2002-02-06 Robert Anisko <robert@lrde.epita.fr>

20233 not expanded by m4.
20235 2002-02-05 Akim Demaille <akim@epita.fr>
20237 * data/bison.c++: Adjust to the M4 back end.
20238 More is certainly needed.
20240 2002-02-05 Akim Demaille <akim@epita.fr>
20242 Give a try to M4 as a back end.
20244 * lib/readpipe.c: New, from wdiff.
20245 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
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
20257 (output_skeleton): Don't look for the skeleton location, let m4 do
20259 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
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
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.
20277 2002-02-05 Akim Demaille <akim@epita.fr>
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.
20283 2002-02-05 Akim Demaille <akim@epita.fr>
20285 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
20286 which have no values.
20288 2002-02-05 Akim Demaille <akim@epita.fr>
20290 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
20293 2002-01-29 Paul Eggert <eggert@twinsun.com>
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).
20299 2002-01-27 Akim Demaille <akim@epita.fr>
20301 Fix `%nonassoc and eof'.
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);
20307 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
20309 * tests/regression.at (%nonassoc and eof): Adjust to newest
20310 Autotest: `.' is not in the PATH.
20312 2002-01-27 Akim Demaille <akim@epita.fr>
20314 * tests/sets.at (AT_EXTRACT_SETS): New.
20315 (Nullable): Use it.
20318 2002-01-26 Akim Demaille <akim@epita.fr>
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.
20324 2002-01-25 Akim Demaille <akim@epita.fr>
20326 * tests/regression.at (%nonassoc and eof): New.
20327 Suggested by Robert Anisko.
20329 2002-01-24 Akim Demaille <akim@epita.fr>
20331 Bison dumps core when trying to complain about broken input files.
20332 Reported by Cris van Pelt.
20334 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
20335 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
20337 (Invalid inputs): Strengthen: exercise parse_percent_token.
20339 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
20341 * src/Makefile.am: Add bison.c++.
20342 * src/bison.c++: New skeleton.
20344 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
20348 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
20350 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
20352 2002-01-20 Marc Autret <marc@gnu.org>
20354 * src/files.c (compute_output_file_names): Fix
20356 2002-01-20 Marc Autret <marc@gnu.org>
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.
20363 2002-01-20 Marc Autret <marc@gnu.org>
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.
20369 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
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).
20376 2002-01-11 Akim Demaille <akim@epita.fr>
20378 * configure.in: Use AC_FUNC_STRNLEN.
20379 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
20381 2002-01-09 Akim Demaille <akim@epita.fr>
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
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.
20395 2002-01-09 Akim Demaille <akim@epita.fr>
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.
20403 2002-01-08 Akim Demaille <akim@epita.fr>
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.
20412 2002-01-08 Akim Demaille <akim@epita.fr>
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
20420 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
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.
20428 2002-01-06 Akim Demaille <akim@epita.fr>
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.
20436 2002-01-06 Akim Demaille <akim@epita.fr>
20438 Bison is dead wrong in its RR conflict reports.
20440 * tests/torture.at (GNU Cim Grammar): New.
20441 * src/conflicts.c (count_rr_conflicts): Fix.
20443 2002-01-06 Akim Demaille <akim@epita.fr>
20445 Creating package.m4 from configure.ac causes too many problems.
20447 * tests/Makefile.am (package.m4): Create it by hand,
20448 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
20450 2002-01-06 Akim Demaille <akim@epita.fr>
20452 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
20455 2002-01-04 Paul Eggert <eggert@twinsun.com>
20457 * doc/bison.texinfo (Debugging):
20458 Remove YYSTDERR; it's no longer defined or used.
20459 Also, s/cstdio.h/cstdio/.
20461 2002-01-03 Akim Demaille <akim@epita.fr>
20463 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
20465 2002-01-03 Akim Demaille <akim@epita.fr>
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
20471 2002-01-03 Akim Demaille <akim@epita.fr>
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/.
20480 2002-01-03 Akim Demaille <akim@epita.fr>
20482 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
20483 for non system headers.
20485 2002-01-02 Akim Demaille <akim@epita.fr>
20487 Equip the skeleton chain with location tracking, runtime trace,
20488 pure parser and scanner.
20490 * src/parse-skel.y: Request a pure parser, locations, and prefix
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.
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.
20502 2001-12-30 Akim Demaille <akim@epita.fr>
20504 * src/parse-skel.y: Get rid of the shift/reduce conflict:
20505 replace `gb' with BLANKS.
20506 * src/scan-skel.l: Adjust.
20508 2001-12-30 Akim Demaille <akim@epita.fr>
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
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.
20521 2001-12-30 Akim Demaille <akim@epita.fr>
20523 * src/skeleton.h: New.
20524 * src/output.c (output_parser, output_master_parser): Remove, dead
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'.
20538 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
20540 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)

20543 (MUSCLE_INSERT_PREFIX): Move from here...
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
20551 * src/files.h (strsuffix, stringappend): Add declarations.
20552 (tab_extension): Add declaration.
20553 (short_base_name): Add declaration.
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
20561 (short_base_name): No longer static.
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.
20569 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
20571 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
20574 * src/parse-skel.y: New file.
20575 * src/scan-skel.l: New file.
20577 2001-12-29 Akim Demaille <akim@epita.fr>
20579 %name-prefix is broken.
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
20586 Renaming yylval but not yylloc is not consistent. Now we do.
20588 * src/bison.simple: Prefix yylloc if used.
20589 * doc/bison.texinfo (Decl Summary): Document that.
20591 2001-12-29 Akim Demaille <akim@epita.fr>
20593 * doc/bison.texinfo: Promote `%long-directive' over
20595 Remove all references to fixed-output-files, yacc is enough.
20597 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20604 2001-12-29 Akim Demaille <akim@epita.fr>
20606 * src/output.c (header_output): Don't forget to export YYLTYPE and
20608 * tests/headers.at (export YYLTYPE): New, make sure it does.
20609 * tests/regression.at (%union and --defines, Invalid CPP headers):
20611 * tests/headers.at: here.
20613 2001-12-29 Akim Demaille <akim@epita.fr>
20615 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
20617 2001-12-29 Akim Demaille <akim@epita.fr>
20619 * tests/actions.at (Mid-rule actions): Output on a single line
20620 instead of several.
20622 2001-12-29 Akim Demaille <akim@epita.fr>
20624 * doc/bison.texinfo: Formatting changes.
20626 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20631 * src/output.c (token_definitions_output): New.
20632 (output_parser, header_output): Use it.
20633 * src/reader.c (symbols_save): Remove.
20635 2001-12-29 Akim Demaille <akim@epita.fr>
20637 * src/bison.simple: Do not provide a default for YYSTYPE and
20638 YYLTYPE before the user's prologue. Otherwise it's hardly... a
20641 2001-12-29 Akim Demaille <akim@epita.fr>
20643 Mid-rule actions are simply... ignored!
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
20648 * tests/actions.at (Mid-rule actions): New.
20650 2001-12-29 Akim Demaille <akim@epita.fr>
20654 * src/reader.c (reader): Free grammar.
20656 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20664 2001-12-29 Akim Demaille <akim@epita.fr>
20666 * src/options.h, src/options.c (create_long_option_table): Rename
20668 (long_option_table_new): this, with a clearer prototype.
20669 (percent_table): Remove, unused,
20670 * src/getargs.c (getargs): Adjust.
20672 2001-12-29 Akim Demaille <akim@epita.fr>
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
20678 2001-12-29 Akim Demaille <akim@epita.fr>
20680 * src/lalr.c (build_relations): Rename `states' as `states1'.
20681 Sorry, I don't understand exactly what it is, no better name...
20683 2001-12-29 Akim Demaille <akim@epita.fr>
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

20695 2001-12-29 Akim Demaille <akim@epita.fr>
20697 * src/reader.c, src/reader.h (user_toknums): Remove.
20698 Adjust all users to use symbols[i]->user_token_number.

20702 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
20703 Adjust all users to use symbols[i]->prec or ->assoc.

20707 * src/reader.c, src/reader.h (tags): Remove.
20708 Adjust all users to use symbols[i]->tag.
20710 2001-12-29 Akim Demaille <akim@epita.fr>
20712 * src/gram.h, src/gram.c (symbols): New, similar to state_table
20714 * src/reader.c (packsymbols): Fill this table.
20716 * src/conflicts.c (resolve_sr_conflict): Adjust.
20717 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
20719 Use symbols[i]->tag instead of tags[i].
20721 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20727 2001-12-29 Akim Demaille <akim@epita.fr>
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
20736 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20743 2001-12-29 Akim Demaille <akim@epita.fr>
20745 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
20746 visible, and some states have now a different number.
20748 2001-12-29 Akim Demaille <akim@epita.fr>
20750 * src/reader.c (readgram): Bind the initial rule's lineno to that
20752 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
20753 (Solved SR Conflicts): Adjust rule 0's line number.
20755 2001-12-29 Akim Demaille <akim@epita.fr>
20757 Fix the `GAWK Grammar' failure.
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
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.
20768 2001-12-29 Akim Demaille <akim@epita.fr>
20770 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
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
20777 2001-12-29 Akim Demaille <akim@epita.fr>
20779 * src/lalr.c (lookaheads_print): New.
20780 (lalr): Call it when --trace-flag.
20781 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
20784 2001-12-29 Akim Demaille <akim@epita.fr>
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.
20796 2001-12-29 Akim Demaille <akim@epita.fr>
20798 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

20804 * src/nullable.c (set_nullable): Likewise.
20806 2001-12-29 Akim Demaille <akim@epita.fr>
20808 * src/output.c: Comment changes.
20810 2001-12-27 Paul Eggert <eggert@twinsun.com>
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.
20817 Also, catch up with 1.31's YYSTD.
20819 2001-12-27 Akim Demaille <akim@epita.fr>
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
20830 2001-12-27 Akim Demaille <akim@epita.fr>
20832 * tests/regression.at (Unresolved SR Conflicts):
20833 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
20836 2001-12-27 Akim Demaille <akim@epita.fr>
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
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.
20856 2001-12-27 Akim Demaille <akim@epita.fr>
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.
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.

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
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.
20892 2001-12-27 Akim Demaille <akim@epita.fr>
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
20898 * lib/strchr.c: New.
20899 * src/reader.c (symbols_save): Use strchr.

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.
20909 2001-12-27 Akim Demaille <akim@epita.fr>
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.

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
20972 2001-12-27 Akim Demaille <akim@epita.fr>
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
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
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
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

21002 * src/reader.c (symbol_list_new): Be sure to initialize all the
21005 2001-12-27 Akim Demaille <akim@epita.fr>
21007 All the hacks using a final pseudo state are now useless.
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).
21014 2001-12-27 Akim Demaille <akim@epita.fr>
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

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.
21038 2001-12-27 Akim Demaille <akim@epita.fr>
21040 * src/bison.hairy: Formatting/comment changes.
21042 Remove `register' indications.
21043 Add plenty of `static'.
21045 2001-12-27 Akim Demaille <akim@epita.fr>
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.
21053 2001-12-22 Akim Demaille <akim@epita.fr>
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
21058 Reported by Wayne Green.
21060 2001-12-22 Akim Demaille <akim@epita.fr>
21062 Some actions of web2c.y are improperly triggered.
21063 Reported by Mike Castle.
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.
21070 2001-12-22 Akim Demaille <akim@epita.fr>
21072 Reductions in web2c.y are improperly reported.
21073 Reported by Mike Castle.
21075 * src/conflicts.c (print_reductions): Fix.
21076 * tests/regression.at (Web2c): New.
21078 2001-12-18 Akim Demaille <akim@epita.fr>
21080 Some host fail on `assert (!"foo")', which expands to
21081 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
21082 Reported by Nelson Beebee.
21084 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
21085 `#define it_succeeded 0' and `assert (it_succeeded)'.
21087 2001-12-17 Marc Autret <autret_m@epita.fr>
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).
21093 2001-12-17 Paul Eggert <eggert@twinsun.com>
21095 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
21096 YYDEBUG must be defined to a nonzero value.
21098 * src/bison.simple (yytname): Do not assume that the user defines
21099 YYDEBUG to a properly parenthesized expression.
21101 2001-12-17 Akim Demaille <akim@epita.fr>
21103 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
21104 nlookaheads is a new member.
21106 * src/lalr.h (nlookaheads): Remove this orphan declaration.
21107 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
21110 2001-12-17 Akim Demaille <akim@epita.fr>
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,
21115 * src/reader.c (reader): Do it.
21117 2001-12-17 Akim Demaille <akim@epita.fr>
21119 * src/conflicts.c (print_reductions): Formatting changes.
21121 2001-12-17 Akim Demaille <akim@epita.fr>
21123 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
21124 (flush_reduce): New.
21125 (resolve_sr_conflict): Adjust.
21127 2001-12-17 Akim Demaille <akim@epita.fr>
21129 * src/output.c (output_obstack): Be static and rename as...
21130 (format_obstack): this, to avoid any confusion with files.c's
21132 * src/reader.h (muscle_obstack): Move to...
21133 * src/output.h: here, since it's defined in output.c.
21135 2001-12-17 Akim Demaille <akim@epita.fr>
21137 * src/output.c (action_row, save_column, default_goto)
21138 (sort_actions, matching_state, pack_vector): Better variable
21141 2001-12-17 Akim Demaille <akim@epita.fr>
21143 * src/output.c: Various formatting changes.
21145 2001-12-17 Akim Demaille <akim@epita.fr>
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.
21153 2001-12-16 Marc Autret <autret_m@epita.fr>
21155 * src/output.c (actions_output): Fix. When we use %no-lines,
21156 there is one less line per action.
21158 2001-12-16 Marc Autret <autret_m@epita.fr>
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
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.
21170 2001-12-15 Marc Autret <autret_m@epita.fr>
21172 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
21174 2001-12-15 Marc Autret <autret_m@epita.fr>
21176 * src/output.c (output_gram): Keep track of the hairy one.
21178 2001-12-15 Akim Demaille <akim@epita.fr>
21180 Make `make distcheck' work.
21182 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
21183 system.h which uses libgettext.h.
21185 2001-12-15 Akim Demaille <akim@epita.fr>
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.
21192 2001-12-15 Akim Demaille <akim@epita.fr>
21194 The header can also be produced directly, without any obstack!
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
21203 (output_token_translations): Merge into...
21204 (symbols_output): this.
21206 (symbols_save): this.
21208 * src/output.c (header_output): New.
21211 2001-12-15 Akim Demaille <akim@epita.fr>
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.
21219 (copy_comment): this.
21221 2001-12-15 Akim Demaille <akim@epita.fr>
21223 * src/lex.c, src/lex.h (xgetc): No longer static.
21224 * src/reader.c (parse_union_decl): Revamp.
21226 2001-12-15 Akim Demaille <akim@epita.fr>
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.
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.
21238 2001-12-15 Akim Demaille <akim@epita.fr>
21240 Attach actions to rules, instead of pre-outputting them to
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.
21251 (prepare): Don't save the `action' muscle.
21252 * src/bison.simple: s/%%action/%%actions/.
21254 2001-12-15 Akim Demaille <akim@epita.fr>
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.
21260 2001-12-14 Akim Demaille <akim@epita.fr>
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.
21266 2001-12-14 Akim Demaille <akim@epita.fr>
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
21274 2001-12-13 Paul Eggert <eggert@twinsun.com>
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.
21281 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
21283 2001-12-13 Akim Demaille <akim@epita.fr>
21285 The computation of nullable is broken: it doesn't handle empty
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.
21293 Work around Autotest bugs.
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
21303 * tests/sets.at: here.
21305 2001-12-13 Akim Demaille <akim@epita.fr>
21307 * src/closure.c (closure): Use nrules instead of playing tricks
21308 with BITS_PER_WORD.
21310 2001-12-13 Akim Demaille <akim@epita.fr>
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
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.
21324 2001-12-13 Akim Demaille <akim@epita.fr>
21326 * src/reader.c (readgram): Remove dead code, an strip useless
21328 (get_type): Remove, unused.
21330 2001-12-12 Akim Demaille <akim@epita.fr>
21332 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
21333 on that of lib/error.c.
21335 2001-12-12 Akim Demaille <akim@epita.fr>
21337 Some hosts don't like `/' in includes.
21339 * src/system.h: Include libgettext.h without qualifying the path.
21340 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
21343 2001-12-11 Marc Autret <autret_m@epita.fr>
21345 * src/output.c (output_parser): Remove useless muscle.
21347 2001-12-11 Marc Autret <autret_m@epita.fr>
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.
21354 2001-12-10 Marc Autret <autret_m@epita.fr>
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.
21361 2001-12-10 Marc Autret <autret_m@epita.fr>
21363 * src/reader.c (symbols_output): Clean up.
21364 * src/output.c (output_gram, output): Clean up.
21366 2001-12-10 Akim Demaille <akim@epita.fr>
21368 * src/lalr.c (initialize_lookaheads): New. Extracted from...
21369 * src/LR0.c (set_state_table): here.
21370 * src/lalr.c (lalr): Call it.
21372 2001-12-10 Akim Demaille <akim@epita.fr>
21374 * src/state.h (shifts): Remove the `number' member: shifts are
21375 attached to state, hence no longer need to be labelled with a
21378 2001-12-10 Akim Demaille <akim@epita.fr>
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.
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.
21391 2001-12-10 Akim Demaille <akim@epita.fr>
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.
21398 2001-12-10 Akim Demaille <akim@epita.fr>
21400 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
21401 only when appropriate: when insert_start_shifting_state' is not
21403 * tests/regression.at (Rule Line Numbers): Adjust.
21405 2001-12-10 Akim Demaille <akim@epita.fr>
21407 * src/LR0.c (augment_automaton): Now that all states have shifts,
21408 merge the two cases addition shifts to the initial state.
21410 2001-12-10 Akim Demaille <akim@epita.fr>
21412 * src/lalr.c (set_state_table): Move to...
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.
21418 2001-12-10 Akim Demaille <akim@epita.fr>
21420 * src/LR0.h (first_shift, first_reduction): Remove.
21421 * src/lalr.c: Don't use first_shift: find shifts through the
21424 2001-12-10 Akim Demaille <akim@epita.fr>
21426 * src/LR0.c: Attach shifts to states as soon as they are
21428 * src/lalr.c (set_state_table): Instead of assigning shifts to
21429 state, just assert that the mapping was properly done.
21431 2001-12-10 Akim Demaille <akim@epita.fr>
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!
21443 2001-12-10 Akim Demaille <akim@epita.fr>
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?
21453 2001-12-10 Akim Demaille <akim@epita.fr>
21455 * src/muscle_tab.c (muscle_init): NULL is a better default than
21458 2001-12-10 Akim Demaille <akim@epita.fr>
21460 * src/reader.c (reader): Calling symbols_output once is enough.
21462 2001-12-10 Akim Demaille <akim@epita.fr>
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
21468 * src/state.h (struct reductions): Remove member `number' and
21470 * src/LR0.c (first_reduction, last_reduction): Remove.
21471 (save_reductions): Don't link the new reductions, store them in
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
21479 2001-12-10 Akim Demaille <akim@epita.fr>
21481 * src/options.c (OPTN, DRTV, BOTH): New.
21482 (option_table): Use them.
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
21489 2001-12-10 Akim Demaille <akim@epita.fr>
21491 * src/output.c (output, prepare): Make sure the values of the
21492 muscles `action' and `prologue' are 0-terminated.
21494 2001-12-10 Akim Demaille <akim@epita.fr>
21496 Clean up GCC warnings.
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.
21506 2001-12-10 Akim Demaille <akim@epita.fr>
21508 * configure.in: Require 2.52g.
21509 M4 is not needed, but AUTOM4TE is.
21510 * m4/m4.m4: Remove.
21511 * tests/Makefile.am: Adjust.
21513 2001-12-10 Akim Demaille <akim@epita.fr>
21515 One structure for states is enough, even though theoretically
21516 there are LR(0) states and LALR(1) states.
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
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.
21529 2001-12-10 Akim Demaille <akim@epita.fr>
21531 Bison dumps core on bash.y.
21532 Reported by Pascal Bart.
21534 * src/warshall.c (bitmatrix_print): New.
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.
21540 2001-12-05 Akim Demaille <akim@epita.fr>
21542 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
21544 Reported by Peter Hamorsky.
21546 2001-12-05 Akim Demaille <akim@epita.fr>

21549 (resolve_sr_conflict): Adjust.
21550 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
21552 (state_t.reductions, state_t.shifts): this.
21554 2001-12-05 Akim Demaille <akim@epita.fr>
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.
21563 2001-12-05 Akim Demaille <akim@epita.fr>
21565 * src/output.c (pack_vector): Use assert, not berror.
21566 * src/main.c (berror): Remove, unused.
21568 2001-12-05 Akim Demaille <akim@epita.fr>
21570 New experimental feature: if --verbose --trace output all the
21571 items of a state, not only its kernel.
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.
21578 2001-12-05 Akim Demaille <akim@epita.fr>
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.
21584 2001-12-05 Akim Demaille <akim@epita.fr>
21586 * src/closure.c (print_closure): Improve.
21587 (closure): Use it for printing input and output.
21589 2001-12-05 Akim Demaille <akim@epita.fr>
21591 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
21592 indexed by nonterminals.
21594 2001-12-05 Akim Demaille <akim@epita.fr>
21596 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

21612 2001-12-05 Akim Demaille <akim@epita.fr>
21614 * src/output.c (action_row): De-obfuscate
21615 using the good o' techniques: arrays not pointers, variable
21616 locality, BITISSET, RESETBIT etc.
21618 2001-12-05 Akim Demaille <akim@epita.fr>
21620 Pessimize the code to simplify it: from now on, all the states
21621 have a valid SHIFTS, which NSHIFTS is possibly 0.
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.
21628 2001-12-05 Akim Demaille <akim@epita.fr>
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''.
21635 2001-12-05 Akim Demaille <akim@epita.fr>
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.
21641 2001-12-05 Akim Demaille <akim@epita.fr>
21643 * src/state.h (SHIFT_SYMBOL): New.

21673 2001-12-05 Akim Demaille <akim@epita.fr>
21675 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
21676 * src/lalr.c: Use them.
21678 2001-12-05 Akim Demaille <akim@epita.fr>
21680 * src/LR0.c (augment_automaton): Formatting changes.
21681 Better variable locality.
21683 2001-12-05 Akim Demaille <akim@epita.fr>
21685 * src/lalr.c (matrix_print): New.
21686 (transpose): Use it.

21689 2001-12-05 Akim Demaille <akim@epita.fr>
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.
21695 2001-12-05 Akim Demaille <akim@epita.fr>
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
21701 Improve variable locality.
21702 Avoid variables used as mere abbreviations.
21703 (compute_lookaheads): Use arrays instead of pointers.
21705 2001-12-05 Akim Demaille <akim@epita.fr>
21707 * src/lalr.c (initialize_F): Improve variable locality.
21708 Avoid variables used as mere abbreviations.
21710 2001-12-05 Akim Demaille <akim@epita.fr>
21712 * src/derives.c (print_derives): Display the ruleno.
21713 * src/lalr.c (initialize_F, transpose): Better variable locality

21721 2001-12-05 Akim Demaille <akim@epita.fr>
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'.
21727 2001-12-05 Akim Demaille <akim@epita.fr>
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.
21734 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
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
21741 Deobfuscate, i.e., allocate, use and free `symbol_count' here
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
21749 2001-12-05 Akim Demaille <akim@epita.fr>
21751 * src/nullable.c (set_nullable): Deobfuscate the handling of
21753 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
21755 2001-12-05 Akim Demaille <akim@epita.fr>
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
21764 2001-12-04 Paul Eggert <eggert@twinsun.com>
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.
21774 2001-11-30 Akim Demaille <akim@epita.fr>
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.
21784 2001-11-27 Paul Eggert <eggert@twinsun.com>
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.
21795 2001-11-29 Paul Eggert <eggert@twinsun.com>
21797 Name space cleanup in generated parser.
21799 * doc/bison.texinfo (Bison Parser): Discuss system headers
21800 and their effect on the user name space.
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).
21807 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
21808 on user names when possible.
21810 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
21811 Simplify test for whather <alloca.h> exists.
21813 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
21815 (<stdio.h>): Include if YYDEBUG.
21817 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
21818 ! defined (yyoverflow) && ! defined (yymemcpy).
21820 (yymemcpy, yyparse): Rename local variables as needed so that
21821 they all begin with 'yy'.
21823 (yystrlen, yystpcpy): New functions.
21825 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
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.
21832 2001-11-30 Akim Demaille <akim@epita.fr>
21834 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
21835 before their first uses.

21845 if body instead of `;' to pacify GCC's warnings.
21847 2001-11-30 Akim Demaille <akim@epita.fr>
21849 Instead of mapping the LHS of unused rules to -1, keep the LHS
21850 valid, but flag the rules as invalid.
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.
21859 2001-11-30 Akim Demaille <akim@epita.fr>

21866 2001-11-30 Akim Demaille <akim@epita.fr>
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.
21873 2001-11-30 Akim Demaille <akim@epita.fr>

21883 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
21884 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
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.
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.
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.
21899 2001-11-29 Marc Autret <autret_m@epita.fr>
21901 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
21902 of defining YYERROR_VERBOSE.

21952 2001-11-28 Akim Demaille <akim@epita.fr>
21954 * src/closure.c (closure): Instead of looping over word in array
21955 then bits in words, loop over bits in array.
21957 2001-11-28 Akim Demaille <akim@epita.fr>
21959 * src/closure.c (closure): No longer optimize the special case
21960 where all the bits of `ruleset[r]' are set to 0, to make the code
21963 2001-11-28 Akim Demaille <akim@epita.fr>
21965 * src/closure.c (closure): `r' and `c' are new variables, used to

21982 From Enrico Scholz.
21984 2001-11-27 Paul Eggert <eggert@twinsun.com>
21986 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
21987 use alloca when we didn't want to, and vice versa.

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.

23734 s/\bENDFILE\b/tok_eof/g;
23735 s/\bIDENTIFIER\b/tok_identifier/g;

23761 introduces a guaranteed SEGV for semantic parsers.

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.
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'.
24139 * tests/calc.m4: Test it.
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'.
24146 2000-10-02 Akim Demaille <akim@epita.fr>
24148 Also test parse error messages, including with YYERROR_VERBOSE.
24150 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
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.
24159 2000-10-02 Akim Demaille <akim@epita.fr>
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:
24180 unfortunately this leads to a CPP conflict when
24181 `--name-prefix=foo' is used since it produces `#define yydebug
24184 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
24185 (YYDPRINTF): New macro.
24187 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
24189 Also test `--verbose', `--defines' and `--name-prefix'.
24191 2000-10-02 Akim Demaille <akim@epita.fr>
24193 Improve the readability of the produced parsers.
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
24200 New variable, `number_of_dollar_signs', to check there's exactly
24201 one `$' in the parser skeleton.
24203 2000-10-02 Akim Demaille <akim@epita.fr>
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.
24211 2000-10-02 Akim Demaille <akim@epita.fr>
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'.
24224 2000-10-02 Akim Demaille <akim@epita.fr>
24226 * src/getargs.c (fixed_outfiles): Rename as...
24227 (yaccflag): for consistency and accuracy.
24228 Adjust dependencies.
24230 2000-10-02 Akim Demaille <akim@epita.fr>
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.
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
24244 Adjust dependencies.
24245 * src/warshall.h: New file.
24248 2000-10-02 Akim Demaille <akim@epita.fr>
24250 Various anti-`extern in *.c' changes.
24252 * src/system.h: Include `assert.h'.
24254 2000-10-02 Akim Demaille <akim@epita.fr>
24256 * src/state.h (nstates, final_state, first_state, first_shift)
24257 (first_reduction): Move their exportation from here...
24258 * src/LR0.h: to here.
24259 Adjust dependencies.
24260 * src/getargs.c (statisticsflag): New variable.
24261 Add support for `--statistics'.
24262 Adjust dependencies.
24264 Remove a lot of now useless `extern' statements in most files.
24266 2000-10-02 Akim Demaille <akim@epita.fr>
24268 * src/LR0.h: New file.
24271 2000-10-02 Akim Demaille <akim@epita.fr>

24297 * src/reduce.h: New file.
24298 Propagate its inclusion.
24299 * src/reduce.c: Topological sort and other formatting changes.
24300 (bool, TRUE, FALSE): Move their definition to...
24301 * src/system.h: here.
24303 2000-10-02 Akim Demaille <akim@epita.fr>
24305 * src/files.c: Formatting changes.
24306 (tryopen, tryclose, openfiles): Rename as...
24307 (xfopen, xfclose, open_files): this.
24308 (stringappend): static.

24332 * src/lalr.c: Formatting changes, topological sorting etc.
24334 2000-10-02 Akim Demaille <akim@epita.fr>
24336 * src/output.c (token_actions): Introduce a temporary array,
24337 YYDEFACT, that makes it possible for this function to use
24338 output_short_table.
24340 2000-10-02 Akim Demaille <akim@epita.fr>
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
24347 * src/reader.c (user_toknums): Be a short table instead of an int

24360 order to get rid of the `static' prototypes.
24361 No longer use `register'.
24362 * src/output.h: New file.
24363 Propagate its inclusion in files explicitly prototyping functions
24366 2000-09-21 Akim Demaille <akim@epita.fr>

24374 functions, use of closure.h.
24375 (initialize_closure, finalize_closure): Rename as...
24376 (new_closure, free_closure): these. Adjust dependencies.
24377 * src/LR0.c: Formatting changes, topological sort, use of

24387 Don't define PARAMS.
24388 * src/system.h: Define PARAMS.
24389 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
24390 purpose of config.h. system.h must not try to fix wrong
24391 definitions in config.h.
24393 2000-09-20 Akim Demaille <akim@epita.fr>
24395 * src/derives.h: New file.

24520 * src/main.c (main): Register `done' to `atexit'.

24587 problems with inline, since it is checked by configure.
24588 (copy_comment): Likewise.
24590 2000-03-17 Akim Demaille <akim@epita.fr>
24592 * src/reader.c (packsymbols): Formatting changes.

24605 (copy_guard): Likewise.
24607 2000-03-17 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,
24613 or, if the rhs is empty, YYLLOC).
24615 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
24617 (yyparse): When providing a default semantic action, provide a
24618 default location action.
24619 (after the $): No longer change `*YYLSP', just stack YYLOC the
24620 same way you stack YYVAL.
24621 * src/reader.c (read_declarations): Use warns.
24622 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
24623 (copy_action, case '@'): Likewise.
24624 Use a standard error message, to save useless work from

24645 2000-03-16 Akim Demaille <akim@epita.fr>
24647 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
24648 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
24649 One `#if YYDEBUG' remains, since it uses variables which are
24650 defined only if `YYDEBUG != 0'.
24652 2000-03-16 Akim Demaille <akim@epita.fr>
24654 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
24655 and related variables so that the similarities are highlighted.

25304 * doc/bison.1, doc/bison.rnh:
25307 1995-10-15 Richard Stallman <rms@gnu.org>
25309 * src/vmsgetargs.c, src/getargs.c:
25310 Added -n, -k, and -raw switches.

25314 New #define for adding aliases to %token.
25315 (struct bucket): Added `alias' field.
25317 * src/reduce.c (reduce_grammar):
25318 Revise error message.
25319 (print_notices): Remove final `.' from error message.
25321 * src/reader.c (reader_output_yylsp):
25323 (readgram): Use `#if 0' around code that accepted %command
25324 inside grammar rules: The documentation doesn't allow it,
25325 and it will fail since the %command processors scan for the next %.
25326 (parse_token_decl): Extended the %token
25327 declaration to allow a multi-character symbol as an alias.
25328 (parse_thong_decl): New function.
25329 (read_declarations): Added %thong declarations.
25330 (read_declarations): Handle NOOP to deal with allowing
25331 % declarations as another means to specify the flags.
25332 (readgram): Allow %prec prior to semantics embedded in a rule.
25333 (skip_to_char, read_declarations, copy_definition)
25334 (parse_token_decl, parse_start_decl, parse_type_decl)
25335 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
25336 (get_type_name, copy_guard, copy_action, readgram)
25337 (get_type, packsymbols): Revised most error messages.
25338 Changed `fatal' to `warnxxx' to avoid aborting for error.
25339 Revised and use multiple warnxxx functions to avoid using VARARGS1.
25340 (read_declarations): Improve the error message for
25341 an invalid character. Do not abort.
25342 (read_declarations, copy_guard, copy_action): Use
25343 printable_version to avoid unprintable characters in printed output.
25344 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
25345 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
25346 Allow the type of a non-terminal can be given
25347 more than once, as long as all specifications give the same type.
25350 (output_headers, output_trailers, output, output_gram)
25351 (output_rule_data): Implement noparserflag variable.
25352 Implement toknumflag variable.
25353 (output): Call reader_output_yylsp to output LTYPESTR.
25355 * src/main.c (main):
25356 If reader sees an error, don't process the grammar.
25357 (fatals): Updated to not use VARARGS1.
25358 (printable_version, int_to_string, warn, warni, warns, warnss)
25359 (warnsss): New error reporting functions. Avoid abort for error.
25362 Added THONG and NOOP for alias processing.
25363 Added SETOPT for the new code that allows setting options with %flags.
25366 Include getopt.h. Add some extern decls.
25367 (safegetc): New function to deal with EOF gracefully.
25368 (literalchar); new function to deal with reading \ escapes.
25369 (lex): Use literalchar.
25370 (lex): Implemented "..." tokens.
25371 (literalchar, lex, parse_percent_token): Made tokenbuffer
25372 always contain the token. This includes growing the token
25373 buffer while reading an integer.
25374 (parse_percent_token): Replaced if-else statement with percent_table.
25375 (parse_percent_token): Added % declarations as another
25376 way to specify the flags -n, -l, and -r. Also added hooks for
25377 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
25378 major changes to files.c.
25379 (lex) Retain in the incoming stream a character following
25381 (skip_white_space, lex): Revised most error messages
25382 and changed fatal to warn to avoid aborting.
25383 (percent_table): Added %thong declarations.
25385 * src/gram.h: Comment changes.
25387 * src/files.c (openfiles, open_extra_files, done):
25389 and actfile file. Handle noparserflag. Both for -n switch.
25391 * src/conflicts.c (resolve_sr_conflict):
25392 Remove use of alloca.
