289 * tests/c++.at (AT_CHECK_VARIANTS): In list.yy, redefine the
290 pretty-printing of lists into something better for parser traces.

384 tests: don't depend on the actual location type.
385 * tests/calc.at: Use yy::parser::location_type rather than
386 yy::location, since the former is always right, and might point to
387 another type than the latter.

490 portability fixes, don't be so optimistic about their success
491 given the lack of feedback on the affected platforms.

495 tests: fix maintainer-xml-check for recent changes.
496 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use
497 AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an
498 output file whose name conflicts with a previous output file
499 is now never generated.

503 portability: fix several issues with M4 subprocess.
505 M4's output pipe was not being drained upon fatal errors during
506 scan_skel. As a result, broken-pipe messages from M4 were seen
507 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
508 failure in the test suite. The problem was that, on platforms
509 where the default disposition for SIGPIPE is ignore instead of
510 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
511 then reported it. However, there's some sort of race condition,
512 because the new test group occasionally succeeded.
513 Reported by Albert Chin at
514 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
516 There were also problems with the test suite livelocking on
517 Tru64 5.1b. Reported by Didier Godefroy at
518 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
519 Switching to create_pipe_bidi suggested by Akim Demaille.
521 To attempt to solve both of these problems, switch to gnulib's
522 create_pipe_bidi and register M4 process as a slave. Along the
523 way, clean up file name conflict handling, which was affected by
524 the broken-pipe problem before the switch.

537 the output file name with /dev/null. Use the /dev/null solution
538 for the case of two conflicting output files as well because it

616 Fix some comments concerning LR(0) versus LALR(1).
618 Stop equating LR(0) with nondeterminism and LALR(1) with
619 determinism. That is, if all states are consistent, then LR(0)
620 tables are deterministic. On the other hand, LALR(1) tables
621 might be nondeterministic before conflict resolution, and GLR

662 portability: `<' and `>' are not always defined on addresses.
663 Specifically, don't sort objects by their memory addresses when
664 they're not allocated in the same array or other object. Though
665 I haven't found a test case where that fails on my platform, C
666 says the behavior is undefined.

687 Fix handling of yychar manipulation in user semantic actions.
688 The problem was that yacc.c didn't always update the yychar
689 translation afterwards. However, other skeletons appear to be
690 fine. glr.c appears to already translate yychar before every
691 use. lalr1.cc does not define yychar and does not document its
692 replacement, yyla, for users. It does provide yyclearin, but
693 that does not manipulate yyla and thus requires no translation
694 update. In lalr1.java, yychar is out of scope during semantic
696 * NEWS (2.5): Document.
697 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
699 (yyparse, yypush_parse): Instead, translate before every use of
700 yytoken, and add comments explaining this approach.
701 * tests/actions.at (Destroying lookahead assigned by semantic
702 action): New test group checking that translation happens before
703 lookahead destructor calls at parser return. Previously,
704 incorrect destructors were called.
705 * tests/conflicts.at (parse.error=verbose and consistent
706 errors): New test group checking that translation happens at
707 syntax error detection before the associated verbose error
708 message and the associated lookahead destructor calls. While
709 the destructor call is fixed by this patch, the verbose error
710 message is currently incorrect due to another bug (see
711 comments in test group), so this is an expected failure for now.

904 yysyntax_error: avoid duplicate lookahead collection.
905 Except when memory reallocation is required, this change
906 eliminates the need to invoke yysyntax_error twice and thus to
907 repeat the collection of lookaheads. It also prepares for
908 future extensions that will make those repetitions more
909 expensive and that will require additional memory management in
910 yysyntax_error. Finally, it fixes an obscure bug already
911 exercised in the test suite.

913 buffer variables stored in the parser. Instead of size, return
914 status similar to yyparse status but indicating success of

1030 lalr1.cc: factor the yytranslate_ invocation in make_SYMBOLS.
1031 * data/c++.m4, data/lalr1.cc (parser::symbol_type): Change the
1032 constructor to take a token_type instead of the (internal) symbol
1035 * data/variant.hh (b4_symbol_constructor_define_): Therefore,

1060 Clean up yacc.c a little.
1061 * data/yacc.c: Clean up M4 for readability, and make output
1062 whitespace more consistent. For the main parse function
1063 comment, instead of saying "yyparse or yypush_parse", say either
1064 "yyparse" or "yypush_parse" depending on which it actually is.

1071 2009-09-09 Akim Demaille <demaille@gostai.com>
1073 lalr1.cc: syntax_error as exceptions.
1074 It is common to use sort of factories in the user actions. These
1075 factories may check some "syntactic" constraints that are not
1076 enforced by the grammar itself. This is possible using YYERROR
1077 within the action itself. Provide the user with a means to throw
1078 a syntax_error exception.
1080 * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
1081 Declare and define yy::parser::syntax_error.

1142 Use aver not assert.
1143 * src/output.c: Don't include assert.h.
1144 (output_skeleton): Use aver not assert.
1145 * src/system.h (aver): In documentation of why, add links to
1146 Paul Eggert's explanations in the mailing lists.
1148 2009-09-05 Alex Rozenman <rozenman@gmail.com>
1150 Use "Unresolved reference" error message when no symbols were found
1151 in a symbolic reference resolution. Remove .expr and -expr from
1152 the shown reference when the reference is unresolved.
1153 * src/scan-code.l: Change the error message, adjust location columns,
1154 rename variable "exact_mode" to "explicit_bracketing".

1161 with ylwrap) when this wrapper is used to compile
1164 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
1166 Complain about unused %define variables and %code qualifiers.
1167 * NEWS (2.5): Document.
1168 * data/bison.m4 (b4_check_user_names): Complain instead of warn.

1170 improve %define documentation a little otherwise.
1171 * tests/input.at (Reject unused %code qualifiers): Update.
1172 (%define errors): Update.

1180 Don't suppress warnings about unused parse.error.
1181 * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
1182 %define variable parse.error unless b4_error_verbose_flag is
1183 actually expanded in a skeleton.

1197 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
1199 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
1200 * src/scan-code.h (code_props_rule_action_init): Rename
1201 named_ref arg to name so it doesn't shadow named_ref type. This
1202 makes it consistent with the function definition in scan-code.l
1205 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
1207 %define: accept unquoted values.
1208 * NEWS (2.5): Group all %define changes together, and document

1239 2009-08-27 Eric Blake <ebb9@byu.net>
1241 scan-gram: avoid portability trap with ctype usage.
1242 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
1243 Avoid compiler warning.
1245 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
1247 tests: use perl for printing special sequences to files.
1248 And skip tests if perl is not available. This is better than
1249 playing tricks with shell portability. Suggested by Akim
1251 * tests/input.at (Bad character literals): Use it here for
1252 omitting final newlines.
1253 (Bad escapes in literals): Use it here for special characters.
1255 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1257 tests: show a use of %define lr.default-reductions "consistent"
1258 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
1259 prevents the omission of expected tokens for %error-verbose.
1261 2009-08-26 Akim Demaille <demaille@gostai.com>
1263 tests: portability fix.
1264 * tests/input.at (Bad escapes in literals): Don't expect "echo
1265 '\0'" to output \ then 0.
1267 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
1269 Actually handle the yytable zero value correctly this time.
1270 * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
1271 zero values in the YYTABLE comments.
1272 * data/glr.c (yytable_value_is_error): Don't check for zero
1274 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
1275 * data/yacc.c (yytable_value_is_error): Likewise.
1276 * data/lalr1.java (yy_table_value_is_error_): Likewise.
1277 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
1278 * src/tables.h: In header comments, explain why it's useless to
1279 check for a zero value in yytable.
1281 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1283 More fixes related to last two patches.
1284 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
1285 comments: zero indicates syntax error not default action.
1286 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
1288 * data/glr.c (yyis_pact_ninf): Rename to...
1289 (yypact_value_is_default): ... this.
1290 (yyisDefaultedState): Update for rename.
1291 (yyis_table_ninf): Rename to...
1292 (yytable_value_is_error): ... this, and check for value zero
1293 besides just YYTABLE_NINF.
1294 (yygetLRActions): Check for default value from yypact. It
1295 appears that this check is always performed before this function
1296 is invoked, and so adding the check here is probably redundant.
1297 However, the code may evolve after this subtlety is forgotten.
1298 Also, update for rename to yytable_value_is_error. Because that
1299 macro now checks for zero, a different but equivalent branch of
1300 the if-then-else here is evaluated.
1301 (yyreportSyntaxError): Update for rename to
1302 yytable_value_is_error. The zero condition was mishandled
1304 (yyrecoverSyntaxError): Update for renames. No behavioral
1306 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
1308 (yy_table_value_is_error_): New function.
1309 (parse): Use new functions where possible. No behavioral
1311 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
1312 The zero condition was mishandled before.
1313 * data/yacc.c (yyis_pact_ninf): Rename to...
1314 (yypact_value_is_default): ... this.
1315 (yyis_table_ninf): Rename to...
1316 (yytable_value_is_error): ... this, and check for value zero
1317 besides just YYTABLE_NINF.
1318 (yysyntax_error): Update for rename to yytable_value_is_error.
1319 The zero condition was mishandled before.
1320 (yyparse): Update for renames. No behavioral changes.
1321 * src/tables.h: Improve comments about yypact, yytable, etc.
1322 more. Most importantly, say yytable value of zero means syntax
1323 error not default action.
1325 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
1327 Fix %error-verbose for conflicts resolved by %nonassoc.

1344 (yyis_table_ninf): Likewise.
1345 (yyreportSyntaxError): Improve internal comments.

1347 Use it everywhere possible.
1348 (yyis_table_ninf): Likewise.
1349 (yysyntax_error): Improve internal comments.
1350 * data/lalr1.cc (yysyntax_error_): Likewise.
1351 * data/lalr1.java (yysyntax_error): Likewise.
1352 * src/tables.h: Improve comments about yypact, yytable, etc.
1354 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
1356 Use locale when quoting.
1357 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
1358 quote rather than implementing quoting here.
1360 2009-08-20 Eric Blake <ebb9@byu.net>
1362 Make previous patch more robust.
1363 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
1365 (output_skeleton): Use it.
1366 Suggested by Akim Demaille.
1368 Import latest m4/m4.m4.
1369 * submodules/autoconf: Update to autoconf 2.64.
1370 * configure.ac (M4_GNU_OPTION): New define.
1371 * src/output.c (output_skeleton): Use it to resolve FIXME.
1372 * NEWS: Mention this.

1376 Fix complaints about escape sequences.
1377 Discussed starting at
1378 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
1379 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
1380 For a \0 and similar escape sequences meaning the null
1381 character, report an invalid escape sequence instead of an
1382 invalid null character because the latter does not actually
1383 appear in the user's input.
1384 In all escape sequence complaints, don't escape the initial
1385 backslash, and don't quote when the sequence appears at the end
1386 of the complaint line unless there's whitespace that quotearg
1388 Consistently say "invalid" not "unrecognized".
1389 Consistently prefer "empty character literal" over "extra
1390 characters in character literal" warning for invalid escape
1391 sequences; that is, consistently discard those sequences.
1392 * tests/input.at (Bad escapes in literals): New.
1394 2009-08-19 Akim Demaille <demaille@gostai.com>
1397 * doc/bison.texinfo: Fix minor Texinfo errors.
1399 2009-08-19 Akim Demaille <demaille@gostai.com>
1401 tests: distcc compliance.

1407 variables: simplify the upgrade of namespace into api.namespace.
1409 This patch simplifies "variables: rename namespace as
1410 api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
1411 Suggested by Joel E. Denny in

1414 * src/muscle-tab.c (muscle_percent_variable_update): New.
1415 (muscle_percent_define_insert): Use it in replacement of the
1416 previous tr invocation.
1417 Remove variable_tr, no longer needed.
1418 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
1420 * data/c++.m4: No longer handle namespace -> api.namespace.
1421 * tests/input.at (%define backward compatibility): Check that
1422 namespace is treated as api.namespace.

1438 2009-08-19 Akim Demaille <demaille@gostai.com>
1440 lalr1.cc: get rid of yyparse's yystate.
1441 yystate and yystack_[0].state are equal, keep only the latter.
1442 The former was also used as a temporary variable to compute the
1443 post-reduction state. Move this computation into an auxiliary
1446 * data/glr.c (yyLRgotoState): Fuse variable definition and first
1448 * data/lalr1.cc (yy_lr_goto_state_): New.
1450 Replace remaining uses of yystate by yystate_[0].state.
1453 2009-08-19 Akim Demaille <demaille@gostai.com>
1455 lalr1.cc: destroy $$ when YYERROR is called.
1456 * data/lalr1.cc (yyreduce): Compute the resulting state before
1457 running the user action so that yylhs is a valid symbol.
1458 (yyerrorlab): Since yylhs is complete (it knows its type), we can
1459 simply call yy_destroy_ to destroy $$ on YYERROR invocations.
1460 * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.

1473 build: require gettext 0.17.
1475 Suggested by Bruno Haible.
1476 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
1477 * configure.ac: require gettext 0.17 to ensure compatibility with

1482 build: lower gettext requirements.
1484 Bison was uselessly requiring the formatstring macros from
1485 gettext, which resulted in mo files not being installed on systems
1486 that perfectly supported Bison mo files. Lower the requirement.
1487 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html

1530 build: fix the generation of the documentation.
1531 Some of our targets use "bison --help", but they can't depend on
1532 "bison" itself (to avoid additional requirements on the user), so
1533 they used to call "make src/bison" in the commands. Then
1534 concurrent builds may fail: one make might be aiming one of its
1535 jobs at compiling src/bison, and another job at generating the man
1536 page. If the latter is faster than the former, then we have two
1537 makes that concurrently try to compile src/bison.
1539 This might also be a more convincing explanation for the failure
1540 described in the patch "build: fix paths".
1542 * Makefile.am (SUFFIXES): Initialize.
1543 * build-aux/move-if-change: New, symlink to gnulib's.

1572 When using $(top_builddir) inconsistently, Make (including GNU
1573 Make) is sometimes confused. As a result it may want to build
1574 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
1575 file, different names) concurrently, which, amusingly enough,
1578 ranlib lib/libbison.a
1579 ranlib lib/libbison.a
1580 make[2]: *** [lib/libbison.a] Segmentation fault

1601 * src/reader.c (reader): Move %define front-end variable
1602 defaults and checking into...
1603 (prepare_percent_define_front_end_variables): ... this new
1606 * src/scan-gram.l (INITIAL): For consistency with string
1607 literals, don't store open quote on character literal. It's
1608 discarded before returning anyway.
1609 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
1610 Make length test more readable, and make the character stored
1611 for an empty literal more obvious while consistent with the
1614 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
1615 USER_NUMBER_HAS_STRING_ALIAS throughout.
1616 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
1617 that is repeated in symtab.h. Improve argument names to make it
1618 clear which side of the symbol-string alias pair is which.
1619 (symbol_check_alias_consistency): Improve local variable names
1620 for the same purpose.
1621 * src/symtab.h (struct symbol): Make comments about aliases
1623 (symbol_make_alias): Improve comments and argument name.
1624 * src/output.c (token_definitions_output): Update for rename to

1638 2009-08-06 Joel E. Denny <jdenny@clemson.edu>
1640 maint: make update-b4-copyright easier to use
1641 * build-aux/update-b4-copyright: In warnings, report line
1642 numbers rather than character positions.
1643 * cfg.mk (update-copyright-local): Set to update-b4-copyright so
1644 that update-copyright runs it.
1647 2009-08-05 Joel E. Denny <jdenny@clemson.edu>
1649 maint: clean up update-b4-copyright code
1650 * build-aux/update-b4-copyright: Do not accept 2-digit
1651 UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
1652 Don't accept a `[' in a b4_copyright argument.
1653 Format code more consistently.
1654 Don't assume b4*copyright never occurs.
1656 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
1658 maint: automate b4_copyright updates.
1659 * Makefile.am (update-b4-copyright): New target rule.
1660 * build-aux/local.mk (EXTRA_DIST): Add update-b4-copyright.
1661 * build-aux/update-b4-copyright: New.
1662 * data/yacc.c: Remove stray characters around b4_copyright
1665 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
1667 maint: automate annual package-wide copyright-year update.
1668 * .x-update-copyright: New.
1669 * Makefile.am (EXTRA_DIST): Remove maint.mk.
1670 * bootstrap.conf (gnulib_modules): Add maintainer-makefile and
1671 update-copyright. Remove gnumakefile, which is implied by
1672 maintainer-makefile.
1673 * cfg.mk (bootstrap-tools): Copy from old maint.mk.
1675 * maint.mk: Remove, now copied from gnulib.
1676 * examples/extexi: Add missing "(C)" in copyright statement so
1677 update-copyright can recognize it.

1690 2009-08-01 Joel E. Denny <jdenny@clemson.edu>
1692 Pacify "gcc -Wunused" for the input function from Flex.
1693 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
1695 * src/scan-code.l: Add "%option noinput", which I cannot find in
1696 the Flex manual, but which Flex has supported since at least as
1697 far back as 2.5.4. However, if any of our developers still use
1698 Flex 2.5.4, they'll need to stop configuring with
1699 --enable-gcc-warnings because "%option noinput" didn't work
1700 correctly until Flex 2.5.6.
1701 * src/scan-gram.l: Likewise.
1702 * src/scan-skel.l: Likewise.
1704 2009-07-31 Alex Rozenman <rozenman@gmail.com>
1706 Fix --enable-gcc-warnings problems.
1707 * src/reader.c: Adjust variable names.
1708 * src/scan-code.l: Fix prototypes and adjust names.

1713 Fix a --enable-gcc-warnings problem.
1714 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
1717 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
1719 Warn about character literals not of length one.
1720 * NEWS (2.5): Document.
1721 * src/scan-gram.l (INITIAL): Remove comment that we don't check
1723 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
1724 * tests/input.at (Bad character literals): New test group.
1726 2009-07-24 Alex Rozenman <rozenman@gmail.com>
1728 Fix some memory leaks.
1729 * src/named-ref.c: Add a pointer check (named_ref_free).
1730 * src/scan-code.l: New function (variant_table_free). Called in
1732 * src/symlist.c: Call to named_ref_free (symbol_list_free).
1734 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
1736 * src/lalr.c (state_lookahead_tokens_count): Correct comment.
1738 2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
1740 Some M4 cleanup in the testsuite.
1741 Suggested by Eric Blake at
1742 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
1743 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
1744 complicate the code by distinguishing between a missing value
1745 and an empty string value for an optional argument. This fix is
1746 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
1747 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
1748 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
1749 arguments are not needed because of the following changes.
1751 Bison developers should use GNU M4 and should not use
1752 POSIXLY_CORRECT when building the test suite, so do not
1753 complicate the code by avoiding $10 and above.
1754 Do not quote an empty string value for an optional argument, and
1755 do not distinguish between a missing value and an empty string
1758 2009-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
1760 Revert unnecessary column realignment in --help output.
1761 Reported by Akim Demaille at
1762 <http://lists.gnu.org/archive/html/bison-patches/2009-06/msg00010.html>.

1775 * src/reader.c: Factoring: assign_named_ref function.
1776 * src/scan-code.l: Factoring and style changes. Rename
1777 parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
1778 Use "unsigned" type for variant index. Improve readablity.
1779 * src/scan-gram.l: Change error messages and add comments.
1780 * src/symlist.h: symbol_list_null: New function decl.
1781 * src/symlist.c: symbol_list_null: Implement here.

1789 2009-06-29 Akim Demaille <demaille@gostai.com>
1791 build: avoid concurrent extraction of calc++.
1792 * examples/calc++/Makefile.am (calc.stamp): New.
1793 Depend on it to create the sources of calc++ so that concurrent
1794 builds don't launch several "extexi" in parallel.
1795 Not only this is inefficient, this also builds incorrect sources
1796 with several extractions mixed together.
1798 2009-06-29 Akim Demaille <demaille@gostai.com>
1801 * data/bison.m4: Move code related to specific variables after the
1802 definition of the variable-maintaining macros so that we don't
1803 "invoke" b4_percent_define_check_values before it is defined.
1805 2009-06-29 Akim Demaille <demaille@gostai.com>
1807 variables: parse.error
1809 Implement, document, and test the replacement of %error-verbose
1810 by %define parse.error "verbose".
1811 * data/bison.m4 (b4_error_verbose_if): Reimplement to track the
1812 values of the parse.error variable.
1813 Make "simple" its default value.
1814 Check the valid values.

1832 * src/reader.h: New argument for symbol_append and
1833 action_append functions.

1839 * src/scan-gram.l: Support bracketed id.
1840 * src/symlist.c: Store named refs in symbol lists.
1841 * src/symlist.h: New field in symbol list: named_ref.

1972 and update muscle_percent_define_insert invocations.
1973 * src/muscle-tab.h (muscle_percent_define_how): New enum type.

2535 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
2536 because location information is bogus.
2537 Use angle brackets to delimit fake file name because square brackets
2538 look like underexpanded m4. Choose a better fake file name.
2539 Use negative line numbers.
2540 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
2541 * src/location.c (location_print): If line for a boundary is negative,
2542 only print that boundary's file name.

2550 * Makefile.am (AM_CFLAGS): Remove $(WERROR_CFLAGS) because many files
2551 in lib won't compile with it.
2552 * src/local.mk (src_bison_CFLAGS): Use $(WERROR_CFLAGS) here only.
2554 2009-03-31 Akim Demaille <demaille@gostai.com>
2556 bootstrap: --help to stdout.
2557 * bootstrap (usage): Don't send --help to stderr.

2583 GCC 4.3 now warns about "a || b && c" and asks for explicit
2585 Reported by Alexandre Duret-Lutz.
2586 * data/location.cc: Update copyright years.
2587 (Position::operator==): Use parens to make precedence explicit.
2588 Compare lines and columns first, as they are more likely to be
2589 different, and they are faster to compare.

2612 Use locations in the variant example.
2613 Yes, this obfuscates the point of this example, variants only.

2834 2008-12-11 Akim Demaille <demaille@gostai.com>
2836 Simplify the i18n of the error messages.
2837 * data/lalr1.cc: Comment changes.
2838 * data/yacc.c (yysyntax_error): Rewrite, using a switch as in

2841 2008-12-08 Akim Demaille <demaille@gostai.com>
2843 Fix portability issue in the test suite.
2844 * tests/local.at (AT_MATCHES_CHECK): New.
2845 Based on Perl instead of Sed. Sed has too many portability
2846 pitfalls, not ever Sed is GNU Sed.

2878 Makefile properly updates atconfig when needed.
2880 2008-12-07 Di-an Jan <dianj@freeshell.org>
2882 Implement the FIXME that ends an user action with a semicolon
2883 if it seems necessary.
2884 * src/scan-code.l (flex rules section): Flag cpp directive from
2885 any `#' to the first unescaped end-of-line. Semicolon is not
2886 needed after `;', `{', '}', or cpp directives and is needed after
2887 any other token (whitespaces and comments have no effect).
2888 * tests/actions.at (Fix user actions without a trailing semicolon):
2890 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
2891 to make user actions complete statements.

2896 2008-12-07 Akim Demaille <demaille@gostai.com>
2899 * gnulib: Update from master.
2901 2008-12-05 Eric Blake <ebb9@byu.net>
2903 Avoid compiler warning.

2907 2008-12-02 Eric Blake <ebb9@byu.net>
2909 Build testsuite with newer autoconf.
2910 * tests/output.at (m4_expand): Don't override in newer autoconf,
2911 where the underlying implementation changed.
2912 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
2913 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
2914 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
2915 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
2916 since some of them contain unbalanced ')'.
2918 2008-12-01 Akim Demaille <demaille@gostai.com>
2920 Use b4_symbol for printers and destructors everywhere.
2921 * data/bison.m4 (b4_symbol_action_location): New.
2922 * data/c.m4 (b4_symbol_actions): Remove.

2927 * src/output.c (symbol_code_props_output): Remove, we no longer
2928 need the b4_symbol_printers/destructors tables.
2930 2008-12-01 Akim Demaille <demaille@gostai.com>
2932 Use b4_symbol_case_.
2933 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
2936 2008-12-01 Akim Demaille <demaille@gostai.com>
2938 Move b4_symbol based macro to bison.m4.

2940 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
2941 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
2942 (b4_type_foreach): Move to...
2943 * data/bison.m4: Here.
2944 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
2945 b4_symbol_value_template instead of b4_symbol_value.
2947 2008-12-01 Akim Demaille <demaille@gostai.com>
2949 b4_symbol/type_foreach.
2950 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
2953 2008-12-01 Akim Demaille <demaille@gostai.com>
2955 Use the symbol properties to output the printer/destructor for lalr1.cc.
2956 Instead of defining complex list of tuples to define various
2957 properties of the symbols, we now prefer to define symbols as
2958 "structs" in m4: using the symbol key (its number), and the
2959 property name, b4_symbol gives it value. Use this to handle
2960 destructors and printers.
2962 * src/output.c (CODE_PROP): New.
2963 (prepare_symbol_definitions): Use it to define the printer and
2964 destructor related attributes of the symbols.
2965 * data/lalr1.cc (b4_symbol_actions): Rename as...
2966 (b4_symbol_action): this.
2967 Use b4_symbol instead of 6 arguments.

2979 Remove spurious empty line before syncline.
2980 * data/bison.m4 (b4_syncline): Don't output an empty line before
2983 2008-11-26 Akim Demaille <demaille@gostai.com>
2985 Convert lib/Makefile.am into lib/local.mk.
2986 The real problem is rather gnulib.mk, which itself is extracted
2987 from a Makefile.am that gnulib expects to the "recursive". The
2988 tool prefix-gnulib-mk converts such a gnulib.mk to be
2989 non-recursive. Also, some AC_SUBST variables need to be adjusted.
2991 * etc/prefix-gnulib-mk: New.
2992 * bootstrap (slurp): Use it to convert further gnulib.mk.
2993 No longer try to avoid re-creation of lib/gnulib.mk as the changes
2995 * lib/Makefile.am: Rename as...
2996 * lib/local.mk: this.
2997 Adjust to be prefixed.
2998 * Makefile.am, configure.ac: Adjust.

3010 Use b4_parser_tables_define in glr.cc.
3011 * data/glr.c: Use b4_parser_tables_define instead of defining the
3012 (deterministic integral) tables by hand.
3014 2008-11-26 Akim Demaille <demaille@gostai.com>
3016 Use b4_parser_tables_define in Java.

3037 (b4_integral_parser_table_define)
3038 (b4_integral_parser_table_declare): these.
3039 (yyrline_): Move the comment where it is actually used.
3040 * data/yacc.c: Adjust.
3041 (yyrline): Use b4_integral_parser_table_define.
3043 2008-11-26 Akim Demaille <demaille@gostai.com>
3046 * src/parse-gram.h, src/parse-gram.c: Regen.
3048 2008-11-26 Akim Demaille <demaille@gostai.com>

3062 2008-11-26 Akim Demaille <demaille@gostai.com>
3064 Get rid of (yy)rhs and (yy)prhs.
3065 These tables are no longer needed in the parsers, and they don't seem to
3066 be useful. They are not documented either.
3068 * src/output.c (prepare_rules): Get rid of rhs and prhs.
3069 Adjust the computation of (yy)r2.
3071 2008-11-26 Akim Demaille <demaille@gostai.com>
3073 Rule length is unsigned.
3074 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
3076 2008-11-26 Akim Demaille <demaille@gostai.com>
3078 Get rid of lalr1-split.cc.
3079 It was no longer maintainer.
3081 * data/lalr1-split.cc: Remove.
3082 * etc/bench.pl.in (bench_fusion_parser): Remove.
3085 2008-11-26 Akim Demaille <demaille@gostai.com>
3087 Use yy* consistently.
3088 * data/glr.c: Now that yyrhs no longer exists as a global
3089 variable, rename local "rhs" variables into "yyrhs" for
3092 2008-11-25 Akim Demaille <demaille@gostai.com>
3094 Get rid of yyrhs and yyprhs in glr.c.
3095 * data/glr.c (yyrhs, yyprhs): Remove.
3096 Instead, use the state stack and yystos.
3098 2008-11-25 Akim Demaille <demaille@gostai.com>
3101 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
3102 as an Autotest keyword.
3104 2008-11-25 Akim Demaille <demaille@gostai.com>
3106 Prefer TESTSUITE_FLAGS.
3107 TESTSUITEFLAGS is barely readable.
3109 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
3110 for backward compatibility.
3111 Use the former instead of the latter.
3113 2008-11-25 Akim Demaille <demaille@gostai.com>
3115 Get rid of yyrhs and yyprhs in larl1.java.
3116 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
3117 (yy_reduce_print): Rather, use yystos_ and the state stack.

3123 2008-11-25 Akim Demaille <demaille@gostai.com>
3125 Get rid of yyrhs and yyprhs in yacc.c.
3126 They were used to get the symbol types, given a rule number, when
3127 displaying the top of the stack before a reduction. But the
3128 symbol type is available from the state stack. This has two be
3129 benefits: two tables less in the parser (making it smaller), and a
3130 more consistent use of the three stacks which will help to fuse
3133 * data/yacc.c (yyprhs, yyrhs): Remove.
3134 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
3135 (yy_reduce_print): Take yyssp as argument.
3136 Use it, together with yystos, to get the symbol type.
3137 * tests/regression.at (Web2c Report): Remove these tables from the
3140 2008-11-25 Akim Demaille <demaille@gostai.com>
3143 The point is to factor the generation of the tables across skeletons.
3144 This is language dependant.
3146 * data/c.m4 (b4_comment_): New.
3147 Should be usable to define how to generate tables independently of
3149 (b4_c_comment): New.
3150 (b4_comment): Bounce to b4_c_comment.
3151 Now support $2 = [PREFIX] for indentation.
3152 * data/lalr1.cc (b4_table_declare): Don't output a comment if
3153 there is no comment.
3154 Indent it properly when there is one.
3155 Output the ending semicolon.
3156 (b4_table_define): Space changes.
3157 Output the ending semicolon.
3158 (b4_tables_map): New.
3159 Use it twice instead of declaring and defining the (integral)
3162 2008-11-25 Akim Demaille <demaille@gostai.com>
3165 * data/lalr1.cc (b4_table_declare): New.
3166 Use it to declare the tables defined with b4_table_define.
3167 (b4_table_define): Declare a third arg to match b4_table_declare
3169 Move all the comments around invocations of b4_table_define into
3170 the invocations itselves.
3171 Move things around to have the order for declarations and

3200 Improves options in the manual.
3201 * doc/bison.texinfo (-g, -x): Add space before argument.
3202 (Option Cross Key): Implement FIXME: listing directives also.
3203 * build-aux/cross-options.pl: Read from <STDIN> rather than <>.
3204 (Short Option): Special case -d. Put arguments inside @option.
3205 (Bison Directive): Add column, automatically extracted from
3206 src/scan-gram.l (actual name passed as the first argument)
3207 with special case for %define.
3208 * doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
3209 to build-aux/cross-options.pl.

3217 <http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00048.html>.
3218 * THANKS (Csaba Raduly): Add.
3219 * data/glr.c: Fix overquoting on b4_prefix for yylval and yylloc.
3220 * tests/calc.at (_AT_DATA_CALC_Y): If %defines is specified, generate
3221 lexer in a separate module that includes the defines file.

3279 (Java Action Features): Remove period to match the rest of menu.
3281 2008-11-17 Di-an Jan <dianj@freeshell.org>
3283 Handles several --enable-gcc-warnings.
3284 * src/getargs.c (command_line_location): Set parameters to void.
3285 * src/output.c (symbol_type_name_cmp): Make static.
3286 (symbols_by_type_name): Set parameters to void.

3292 (AT_CHECK_NAMESPACE): Make unused parameter lloc unnamed.
3294 2008-11-17 Di-an Jan <dianj@freeshell.org>
3296 * tests/c++.at (AT_CHECK_VARIANTS): Fixes tests 198-202.
3297 Use AT_DATA_GRAMMAR instead of AT_DATA for compiled tests.
3299 2008-11-16 Akim Demaille <demaille@gostai.com>
3301 Add missing $(EXEEXT).

3322 * src/parse-gram.h, src/parse-gram.c: Regen.
3324 2008-11-15 Akim Demaille <demaille@gostai.com>
3326 Support parametric types.
3328 There are two issues to handle: first scanning nested angle
3329 bracket pairs to support types such as std::pair< std::string,
3330 std::list<std::string> > >.
3332 Another issue is to address idiosyncracies of C++: do not glue two
3333 closing angle brackets together (otherwise it's operator>>), and
3334 avoid sticking blindly a TYPE to the opening <, as it can result
3335 in '<:' which is a digraph for '['.
3337 * src/scan-gram.l (brace_level): Rename as...
3340 Implement support for complex tags.
3343 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
3344 (b4_symbol_variant): Leave space around types as parameters.
3345 * examples/variant.yy: Use nested template types and leading ::.
3346 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
3348 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
3349 * tests/c++.at: Test parametric types.
3351 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
3354 This is not sufficient, but we test at least that the make_SYMBOL
3355 interface is not affected by token.prefix. A more general test
3356 will be implemented when the support of token.prefix is generalized
3359 * tests/c++.at: One more variant test, using token.prefix.
3361 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
3363 Test the make_TOKEN interface.

3395 2008-11-15 Akim Demaille <demaille@gostai.com>
3398 * data/local.mk, etc/local.mk, examples/local.mk: Use Automake
3399 comments for the license.

3433 Move sc_tight_scope into maint.mk.
3434 It does not work, and I don't know how it was supposed to work: it
3435 seems to be looking for sources in the build tree. I just moved
3436 it at a better place, fixing it is still required.

3458 It used to bounce to the version in src/Makefile.am which is now
3459 part of this very Makefile.
3460 * Makefile.am, configure.ac: Adjust.
3461 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
3462 include "..." to find files "here": we are no longer in src/, so
3463 qualify the includes with src/.
3464 * doc/Makefile.am (PREPATH): No longer include the top_builddir

3515 Provide convenience constructors for locations and positions.
3516 * data/location.cc (position::position): Accept file, line and
3517 column as arguments with default values.
3518 Always qualify initial line and column literals as unsigned.
3519 (location::location): Provide convenience constructors.
3521 2008-11-15 Akim Demaille <demaille@gostai.com>
3523 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
3525 Using template buys us nothing, and makes it uselessly complex to
3526 construct a symbol. Besides, it could not be generalized to other
3527 languages, while make_FOO would work in C/Java etc.
3529 * data/lalr1.cc (b4_symbol_): New.
3530 (b4_symbol): Use it.
3531 (b4_symbol_constructor_declaration_)
3532 (b4_symbol_constructor_definition_): Instead of generating
3533 specializations of an overloaded template function, just generate
3534 several functions whose names are forged from the token names
3535 without the token.prefix.
3536 (b4_symbol_constructor_declarations): Generate them for all the
3537 symbols, not just by class of symbol type, now that instead of
3538 specializing a function template by the token, we generate a
3539 function named after the token.
3540 (b4_symbol_constructor_specialization_)
3541 (b4_symbol_constructor_specializations): Remove.
3542 * etc/bench.pl.in: Adjust to this new API.
3544 2008-11-13 Akim Demaille <demaille@gostai.com>
3546 %define token.prefix.
3547 Provide a means to add a prefix to the name of the tokens as
3548 output in the generated files. Because of name clashes, it is
3549 good to have such a prefix such as TOK_ that protects from names
3550 such as EOF, FILE etc. But it clutters the grammar itself.
3552 * data/bison.m4 (token.prefix): Empty by default.
3553 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
3554 * data/lalr1.cc (b4_symbol): Ditto.
3556 2008-11-13 Akim Demaille <demaille@gostai.com>
3558 Compute at M4 time some of the subtractions.
3559 * data/lalr1.cc (b4_subtract): New.
3560 (b4_rhs_data): Use it.
3562 2008-11-13 Akim Demaille <demaille@gostai.com>
3565 This allows the user to get the type of a token returned by yylex.
3567 * data/lalr1.cc (symbol::token): New.
3568 (yytoknum_): Define when %define lex_symbol, independently of
3570 (yytoken_number_): Move into...
3571 (symbol::token): here, since that's the only use.
3572 The other one is YYPRINT which was not officially supported
3573 by lalr1.cc, and anyway it did not work since YYPRINT uses this
3574 array under a different name (yytoknum).
3576 2008-11-13 Akim Demaille <demaille@gostai.com>

3590 yytranslate and yytoknum tables.
3592 2008-11-13 Akim Demaille <demaille@gostai.com>
3594 Define make_symbol in the header.
3595 To reach good performances these functions should be inlined (yet
3596 this is to measure precisely). To this end they must be available
3599 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
3600 location_type with the class name.
3601 Since will now be output in the header, declare "inline".
3602 No longer use b4_symbol_constructor_specializations, but
3603 b4_symbol_constructor_definitions in the header.
3604 Don't call it in the *.cc file.
3606 2008-11-13 Akim Demaille <demaille@gostai.com>
3608 Define yytranslate in the header for lex_symbol.
3609 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
3610 into the header file when using %define lex_symbol.
3611 (yytranslate_): Declare inline.
3613 2008-11-13 Akim Demaille <demaille@gostai.com>
3615 Define the constructors of symbol_type in
3616 b4_symbol_constructor_definitions.
3617 The constructors are called by the make_symbol functions, which a
3618 forthcoming patch will move elsewhere. Hence the interest of
3619 putting them together.
3621 The stack_symbol_type does not need to be moved, it is used only
3624 * data/lalr1.cc: Move symbol_type and symbol_base_type
3625 constructors into...
3626 (b4_symbol_constructor_definitions): here.
3629 2008-11-13 Akim Demaille <demaille@gostai.com>
3631 Make it easier to move the definition of yytranslate_.
3632 Forthcoming changes will make it possible to use yytranslate_
3633 from outside the parser implementation file.
3635 * data/lalr1.cc (b4_yytranslate_definition): New.

3640 Remove useless class specification.
3641 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
3642 to refer to the class name to use a type defined by the class for
3643 arguments of member functions.
3645 2008-11-13 Akim Demaille <demaille@gostai.com>
3647 Finer input type for yytranslate.
3648 This patch is debatable: the tradition expects yylex to return an int
3649 which happens to correspond to token_number (which is an enum). This
3650 allows for instance to return characters (such as '*' etc.). But this
3651 goes against the stronger typing I am trying to have with the new
3652 lex interface which return a symbol_type. So in this case, feed
3653 yytranslate_ with a token_type.
3655 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
3656 expect a token_type.
3658 2008-11-13 Akim Demaille <demaille@gostai.com>
3660 Honor lex-params in %define lex_symbol mode.
3661 * data/lalr1.cc: Use b4_lex_param.
3663 2008-11-13 Akim Demaille <demaille@gostai.com>
3666 * src/output.c (symbol_definitions_output): Rename symbol
3667 attributes type_name and has_type_name as type and has_type.
3668 * data/lalr1.cc: Adjust uses.
3670 2008-11-13 Akim Demaille <demaille@gostai.com>
3672 Use b4_type_names for the union type.
3673 The union used to compute the size of the variant used to iterate
3674 over the type of all the symbols, with a lot of redundancy. Now
3675 iterate over the lists of symbols having the same type-name.
3677 * data/lalr1.cc (b4_char_sizeof_): New.
3678 (b4_char_sizeof): Use it.
3679 Adjust to be called with a list of numbers instead of a single
3681 Adjust its caller for new-line issues.
3683 2008-11-13 Akim Demaille <demaille@gostai.com>
3685 Define the "identifier" of a symbol.
3686 Symbols may have several string representations, for instance if
3687 they have an alias. What I call its "id" is a string that can be
3688 used as an identifier. May not exist.
3690 Currently the symbols which have the "tag_is_id" flag set are
3691 those that don't have an alias. Look harder for the id.
3693 * src/output.c (is_identifier): Move to...
3694 * src/symtab.c (is_identifier): here.
3695 * src/symtab.h, src/symtab.c (symbol_id_get): New.
3696 * src/output.c (symbol_definitions_output): Use it to define "id"
3698 Remove the definition of "tag_is_id".
3699 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
3700 "tag_is_id" were used to produce code.
3701 We still use "tag" for documentation.
3703 2008-11-11 Akim Demaille <demaille@gostai.com>
3705 Locations are no longer required by lalr1.cc.
3706 * data/lalr1.cc (_b4_args, b4_args): New.
3707 Adjust all uses of locations to make them optional.
3708 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
3709 (AT_CHECK_NAMESPACE): Check the use of locations.
3710 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
3711 without locations with lalr1.cc.
3713 * tests/output.at: Check lalr1.cc with and without location
3715 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
3716 Don't use locations.
3718 2008-11-11 Akim Demaille <demaille@gostai.com>
3721 * tests/local.at (AT_FULL_COMPILE): New.
3722 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
3724 2008-11-11 Akim Demaille <demaille@gostai.com>
3726 Support parens in calc++.
3727 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
3728 * examples/calc++/test (run): Check the expected output.
3732 2008-11-11 Akim Demaille <demaille@gostai.com>
3734 Simplify lalr1.cc since %defines is mandatory.
3735 * data/lalr1.cc: Remove useless calls to b4_defines_if.
3737 2008-11-11 Akim Demaille <demaille@gostai.com>
3740 * TODO (yysyntax_error): New item.
3742 2008-11-11 Akim Demaille <demaille@gostai.com>
3745 * data/lalr1.cc: Use b4_error_verbose_if instead of #if
3748 2008-11-11 Akim Demaille <demaille@gostai.com>
3750 Support i18n of the parse error messages.
3751 * TODO (lalr1.cc/I18n): Remove.
3752 * data/lalr1.cc (yysyntax_error_): Support the translation of the
3753 error messages, as done in yacc.c.
3754 Stay within the yy* pseudo namespace.
3756 2008-11-11 Akim Demaille <demaille@gostai.com>
3759 * TODO (single stack, yysyntax_error): New.
3761 2008-11-11 Akim Demaille <demaille@gostai.com>
3763 Make it possible to return a symbol_type from yylex.
3764 * data/lalr1.cc (b4_lex_symbol_if): New.
3765 (parse): When lex_symbol is defined, expected yylex to return the
3767 * etc/bench.pl.in (generate_grammar_list): Extend to support this
3769 (bench_variant_parser): Exercise it.
3771 2008-11-11 Akim Demaille <demaille@gostai.com>
3773 Remove useless bench case.
3774 * etc/bench.pl.in (bench_variant_parser): VARIANT_DESTROY is
3777 2008-11-11 Akim Demaille <demaille@gostai.com>
3779 Improve display of directives.
3780 * etc/bench.pl.in (parse_term): Don't add useless eol.
3782 2008-11-11 Akim Demaille <demaille@gostai.com>
3784 Use string_cast in the bench.
3785 * etc/bench.pl.in (generate_grammar_list): Define and use
3788 2008-11-11 Akim Demaille <demaille@gostai.com>
3790 Replace yychar with a Boolean.
3791 * data/lalr1.cc (parse::yychar): Replace by...
3792 (parse::yyempty): this.
3794 2008-11-11 Akim Demaille <demaille@gostai.com>
3799 2008-11-11 Akim Demaille <demaille@gostai.com>
3801 Let yytranslate handle the eof case.
3802 * data/lalr1.cc (yytranslate_): Handle the EOF case.
3804 No longer expect yychar to be equal to yyeof_, rather, test the
3805 lookahead's (translated) kind.
3807 2008-11-11 Akim Demaille <demaille@gostai.com>
3809 yychar cannot be empty in yyerrlab.
3810 * TODO (yychar == yyempty_): New.
3811 * data/lalr1.cc: Remove the handling of this case.
3812 This eases forthcoming changes related to yychar and yytranslate.
3814 2008-11-11 Akim Demaille <demaille@gostai.com>
3816 Bench: syntactic sugar for %define/#define.

3822 2008-11-11 Akim Demaille <demaille@gostai.com>
3824 Less memory pressure on the "list" bench.
3825 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
3826 the values, to limit memory pressure.
3828 2008-11-11 Akim Demaille <demaille@gostai.com>
3830 Introduce make_symbol.
3831 make_symbol provides a means to construct a full symbol (kind,
3832 value, location) in a single shot. It is meant to be a Symbol
3833 constructor, parameterized by the symbol kind so that overloading
3834 would prevent incorrect kind/value pairs. Unfortunately
3835 parameterized constructors do not work well in C++ (unless the
3836 parameter also appears as an argument, which is not acceptable),
3837 hence the use of a function instead of a constructor.
3839 * data/lalr1.cc (b4_symbol_constructor_declaration_)
3840 (b4_symbol_constructor_declarations)
3841 (b4_symbol_constructor_specialization_)
3842 (b4_symbol_constructor_specializations)
3843 (b4_symbol_constructor_definition_)
3844 (b4_symbol_constructor_definitions): New.
3845 Use them where appropriate to generate declaration, declaration of
3846 the specializations, and implementations of the templated
3847 overloaded function "make_symbol".
3848 (variant::variant): Always define a default ctor.
3849 Also provide a copy ctor.
3850 (symbol_base_type, symbol_type): New ctor overloads for value-less
3852 (symbol_type): Now public, so that functions such as yylex can use
3855 2008-11-11 Akim Demaille <demaille@gostai.com>
3857 Inform m4 whether a tag is a valid id.
3858 * src/output.c (is_identifier): New.
3859 (symbol_definitions_output): Use it to define tag_is_id.
3860 But maybe this should be done at m4 level?
3862 2008-11-11 Akim Demaille <demaille@gostai.com>
3864 Test 214 was failing: it greps with a pattern containing [ ]*
3865 which obviously meant to catch spaces and tabs, but contained only
3866 spaces. Tabulations in sources are a nuisance, so to simplify the
3867 matter, get rid of all the tabulations in the Java sources. The
3868 other skeletons will be treated equally later.
3870 * data/java.m4, data/lalr1.java: Untabify.
3871 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
3872 tabulations are no longer generated.
3874 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
3876 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
3877 * configure.ac: Adjust usage.
3878 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
3879 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
3880 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
3882 2008-11-10 Di-an Jan <dianj@freeshell.org>
3884 Workaround Java's ``code too large'' problem for parser tables
3885 in most cases, by using one function per initialization.
3886 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
3887 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
3888 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_

3898 General Java skeleton improvements.
3899 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
3900 using gcj < 4.3 in the testsuite, according to comments in
3901 gnulib/m4/javacomp.m4.
3902 * data/java.m4 (stype, parser_class_name, lex_throws, throws,
3903 location_type, position_type): Remove extraneous brackets from
3904 b4_percent_define_default.
3905 (b4_lex_param, b4_parse_param): Remove extraneous brackets from
3906 m4_define and m4_define_default.

3908 which marks the end of user code with appropriate syncline, like all
3909 the other skeletons.
3910 (b4_user_post_prologue): Add. Don't silently drop.
3912 (parse): Inline yylex.
3913 * doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
3914 (%{...%}): Fix typo of %code imports.
3915 * tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
3917 Support annotations on parser class with %define annotations.

3934 Move constants for token names to Lexer interface.
3935 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.

3977 including those that don't have a type-name.
3978 (symbol_definitions_output): Define "is_token" and
3980 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
3981 type-name, now that they are defined too in b4_type_names.

3987 2008-11-10 Akim Demaille <demaille@gostai.com>
3989 Make parser::yytranslate static.
3990 Small speedup (1%) on the list grammar. And makes yytranslate_
3991 available in non member functions.

3998 Avoid trailing spaces.
3999 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
4000 * data/lalr1.cc: Don't indent before rule and symbol actions, as
4001 they can be empty, and anyway this incorrectly indents the first

4013 * data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
4014 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.

4050 2008-11-10 Akim Demaille <demaille@gostai.com>
4052 Change the handling of the symbols in the skeletons.
4053 Before we were using tables which lines were the symbols and which
4054 columns were things like number, tag, type-name etc. It is was
4055 difficult to extend: each time a column was added, all the numbers had
4056 to be updated (you asked for colon $2, not for "tag"). Also, it was
4057 hard to filter these tables when only a subset of the symbols (say the
4058 tokens, or the nterms, or the tokens that have and external number
4059 *and* a type-name) was of interest.
4061 Now instead of monolithic tables, we define one macro per cell. For
4062 instance "b4_symbol(0, tag)" is a macro name which contents is
4063 self-decriptive. The macro "b4_symbol" provides easier access to
4066 * src/output.c (type_names_output): Remove.
4067 (symbol_numbers_output, symbol_definitions_output): New.
4068 (muscles_output): Call them.
4069 (prepare_symbols): Define b4_symbols_number.

4098 This improves the "list" bench by 2%.
4100 * data/lalr1.cc (variant::build): Add an overloaded version with

4108 Use it with and without %define assert.
4110 2008-11-10 Akim Demaille <demaille@gostai.com>
4112 Add %precedence support.
4113 Unfortunately it is not possible to reuse the %prec directive. This
4114 is because to please POSIX, we do not require to end the rules with a
4115 semicolon. As a result,
4119 is ambiguous: either a rule which precedence is that of baz, or a rule,
4120 and then a declaration of the precedence of the token baz.
4122 * doc/bison.texinfo: Document %precedence.
4123 (Precedence Only): New.
4124 * src/assoc.h, src/assoc.c (precedence_assoc): New.

4129 * tests/conflicts.at (%precedence does not suffice)
4130 (%precedence suffices): New tests.

4382 Add "%define assert" to variants.
4383 This is used to help the user catch cases where some value gets
4384 ovewritten by a new one. This should not happen, as this will
4387 Unfortunately this uncovered a bug in the C++ parser itself: the
4388 lookahead value was not destroyed between two calls to yylex. For
4389 instance if the previous lookahead was a std::string, and then an int,
4390 then the value of the std::string was correctly taken (i.e., the
4391 lookahead was now an empty string), but std::string structure itself
4394 This is now done in variant::build(other&) (which is used to take the
4395 value of the lookahead): other is not only stolen from its value, it
4396 is also destroyed. This incurs a new performance penalty of a few
4397 percent, and union becomes faster again.

4676 2008-11-03 Akim Demaille <demaille@gostai.com>
4678 Fuse the three stacks into a single one.
4680 In order to make it easy to perform benchmarks to ensure that
4681 there are no performance loss, lalr1.cc is forked into
4682 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
4685 Meanwhile, to make sure that lalr1-fusion.cc is correctly
4686 exercized by the test suite, the user must install a symbolic link
4687 from lalr1.cc to it.
4689 Instead of having three stacks (state, value, location), use a
4690 stack of triples. This considerably simplifies the code (and it
4691 will be easier not to require locations as currently does the C++
4692 parser), and also gives a 10% speedup according to
4693 etc/bench (probably mainly since memory allocation is done once
4694 instead of three times).
4696 Another motivation is to make it easier to destruct properly
4697 semantic values: now that they are bound to their state (hence
4698 symbol type) it will be easier to call the appropriate destructor.
4700 These changes should probably benefit the C parser too.
4702 * data/lalr1.cc: Copy as...
4703 * data/lalr1-fusion.cc: this new file.
4704 (b4_rhs_value, b4_rhs_location): New definitions overriding those
4706 (state_stack_type, semantic_stack_type, location_stack_type)

4715 This is needed to prepare a forthcoming patch that fuses the three
4718 * data/lalr1.cc (parser::yypush_): New.
4719 (parser::yynewstate): Change the semantics: instead of arriving to
4720 this label when value and location have been pushed, but yystate
4721 is to be pushed on the state stack, now the three of them must
4722 have been pushed before. yystate still must be the new state.
4723 This allows to use yypush_ everywhere instead of individual
4724 handling of the stacks.

4745 Use variants to support objects as semantic values.
4746 This patch was inspired by work by Michiel De Wilde. But he used
4747 Boost variants which (i) requires Boost on the user side, (ii) is
4748 slow, and (iii) has useless overhead (the parser knows the type of
4749 the semantic value there is no reason to duplicate this
4750 information as Boost.Variants do).
4752 This implementation reserves a buffer large enough to store the
4753 largest objects. yy::variant implements this buffer. It was
4754 implemented with Quentin Hocquet.

4763 (parser::parse): If variants are requested, define
4764 parser::union_type, parser::variant, change the definition of
4765 semantic_type, construct $$ before running the user action instead
4766 of performing a default $$ = $1.
4767 * examples/variant.yy: New.
4768 Based on an example by Michiel De Wilde.
4770 2008-11-03 Akim Demaille <demaille@gostai.com>
4772 Parameterize the extraction of semantic values.

4887 Always put auxiliary code files in the same dir as other output files.
4888 * src/files.c (compute_file_name_parts): When the user specifies
4889 --output but not --file-prefix, extract the directory prefix from the

5155 .prev-version, and .version.
5156 * NEWS (2.3b+): Rename to...
5157 (?.?): ... this because we're dropping the "+" version naming scheme,
5158 but, in general, we still can't be sure of our next release name.
5159 * bootstrap: Add a quick hack to remove from .gitignore the
5160 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

5212 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
5214 Improve forward-compatibility with GNU M4. Reported by Eric Blake at
5215 <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.

5285 2008-04-23 Eric Blake <ebb9@byu.net>
5287 Revert prior patch, by working around autoconf regression.
5288 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
5289 ("Output file name: ("): Uncomment test.
5290 ("Output file name: )"): Likewise.
5291 Based on an idea from Noah Misch.
5293 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5295 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
5296 2.61. Reported by Juan Manuel Guerrero at
5297 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
5298 * tests/output.at ("Output file name: ("): Comment out test case for
5300 ("Output file name: )"): Likewise.

5304 * GNUmakefile: Update git-version-gen invocation so make dist
5307 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
5309 Update to the current gnulib CVS repository, and fix trigraph handling
5311 * bootstrap: Update gnulib CVS repository URL.
5312 (symlink_to_dir): Encapsulate the code that guarantees the destination
5313 directory exists into...
5314 (check_dst_dir): ... this new function, and...
5315 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
5316 fail when copying files into lib/uniwidth/.
5317 * src/output.c (prepare_symbols): When writing yytname muscles, where
5318 symbol names will be encoded in C-string literals, tell quotearg to
5319 escape trigraphs. This used to be the default in gnulib.
5320 * tests/regression.at (Token definitions): Because of the change in
5321 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
5322 escapes trigraphs in symbol names. Thus, yytname no longer has
5323 trigraphs unnecessarily doubly escaped. Update test case output.
5324 Extend test case to be sure Bison's own error messages will no longer
5325 have trigraphs in symbol names unnecessarily escaped once.

5340 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
5341 consistency. Update the -g and -x entries now that they take
5342 arguments. Use brackets to indicate optional arguments.
5343 * src/getargs.c (usage): Explain the relationship between arguments of
5344 long and short options more completely. Document --defines and -d
5345 separately since the former takes an argument but, for POSIX Yacc, the
5347 (short_options): Let -W take an optional argument like --warnings.

5365 Fix the handling of $opt which resulted in all the argument to be
5366 considered as optional.

6153 local variable `sep'.
6155 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
6157 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
6159 * src/print-xml.c: Prefer "const" after types; that's more consistent.
6160 (xml_printf): Indent just 1 space for level.
6161 (e_char, xlate_char): Remove.
6162 (xml_escape_string): Rewrite to avoid undefined behavior (used
6163 storage that was freed from the stack).
6164 (xml_escape_n): Don't bother checking for subscript error.
6166 2007-09-21 Wojciech Polak <polak@gnu.org>

6218 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
6219 and is a script that invokes bison. Tighten the code. Add comments.
6221 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

6233 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
6235 In impure push mode, don't allow more than one yypstate to be allocated
6236 since multiple impure parsers would corrupt yynerrs.
6237 * data/push.c (yypstate_allocated): New static global variable
6239 (yypull_parse): If yypstate_new returns 0, don't report it as memory
6240 exhaustion if yypstate_allocated is 1, but still return 2.
6241 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
6242 already 1. Otherwise, set it to 1.
6243 (yypstate_delete): Set it to 0.

6318 Get rid of broken %no-parser, -n, and --no-parser implementation and
6320 * TODO: Don't mention them.
6321 * doc/bison.1: Likewise.
6322 * doc/bison.texinfo (Decl Summary): Likewise.
6323 (Bison Options): Likewise.
6324 (Option Cross Key): Likewise.
6325 * src/getargs.c (no_parser_flag): Remove global variable.
6326 (usage): Don't print description of -n and --no-parser.
6327 (long_options): Remove --no-parser entry here.
6328 (getargs): Remove -n case in the switch here.
6329 * src/getargs.h (no_parser_flag): Remove extern.
6330 * tests/regression.at (Web2c Actions): Remove comment that mentions
6333 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
6335 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
6336 name user variables starting with `yy'. Just pass NULL instead of a
6337 dummy local &yylval to yypush_parse.
6338 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
6341 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
6343 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
6344 true since it's then always used regardless of whether yyoverflow is
6345 defined. Reported by Christian Burger at
6346 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
6347 * THANKS: Add Christian Burger.
6349 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6350 node names: say "Decl Summary" not "Bison Declaration Summary".
6352 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
6354 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
6355 determine whether this function has already complained about an invalid
6356 value for a %define boolean variable, don't check whether Bison has
6357 ever examined the value. As written, the check was a tautology.
6358 Instead, record and check for this complaint using a separate muscle.
6360 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
6362 Fix push parsing memory leak reported by Brandon Lucia at
6363 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
6364 * THANKS: Add Brandon Lucia.
6365 * data/push.c (yypstate_delete): Free the stack if it was reallocated
6366 but the parse never completed and thus freed it.
6367 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
6368 * tests/testsuite.at: Include push.at.
6369 * test/push.at: New.
6370 (Push Parsing: Memory Leak for Early Deletion): New test case.
6372 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
6374 Improve handling of multiple S/R conflicts in the same state and of S/R
6375 conflicts involving multiple reductions.
6376 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
6377 set for a state here or Bison will abort if it is reassigned on a
6378 later conflicted reduction in the same state.
6379 Similarly, don't finalize and assign the solved conflicts report here
6380 or it will be lost if it is reassigned on a later conflicted reduction
6382 (set_conflicts): Instead, assign them both here after all S/R conflicts
6383 in the state have been fully examined.
6384 * src/print.c (shift_set): Rename to...
6385 (no_reduce_set): ... this.
6386 (print_reductions): Update for rename, and add %nonassoc error action
6387 tokens to no_reduce_set so that, when printing the first remaining
6388 reduction on an error action token, the reduction is enclosed in
6390 (print_results): Update for rename.
6391 * tests/conflicts.at (Solved conflicts report for multiple reductions
6392 in a state): New test case.
6393 (%nonassoc error actions for multiple reductions in a state): New test
6396 * src/main.c (main): Don't depend on C99 features.
6398 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
6400 * build-aux/.cvsignore: Add compile.
6401 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
6404 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
6406 * bootstrap (slurp): Create target directories that don't exist.
6407 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
6409 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6411 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
6413 * closure.c (closure): Likewise.
6414 * state.h (reductions): Comment sorting of rules.
6415 (state): Comment sorting of items.
6417 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
6419 Fix C++ test cases after recent Gnulib changes. Discussed starting at
6420 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
6421 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
6422 definition in order to avoid Gnulib headers since we don't use config.h
6424 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
6425 rather than AT_DATA so that config.h is included.
6427 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
6429 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
6430 instead of fprintf. Guard these functions with #if YYDEBUG instead of
6431 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
6432 and so that YYFPRINTF is guaranteed to be defined here.
6434 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6436 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
6438 (muscle_percent_define_check_values): ... this more helpful function.
6439 Again, it's not used yet, but it will be.
6440 * src/muscle_tab.h: Likewise.
6442 Improve some comments in parser table construction.
6443 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
6444 (generate_states): Don't mention ruleset, which is internal to closure.
6445 * src/closure.c (closure): Explain sorting of core and itemset, which
6446 is required for this function to behave correctly.
6447 * src/closure.h (closure): Mention sorting.
6449 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
6451 * src/lalr.c (state_lookahead_tokens_count): For code readability,
6452 move the check for disabled transitions to an aver since conflict
6453 resolution hasn't happened yet.
6455 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
6456 labels a state as inconsistent just because it has error transitions.
6457 The original form of this check appeared in revision 1.1 of lalr.c,
6458 which was committed on 1991-12-21. Now (at least), changing the
6459 consistency label on such a state appears to have no useful effect in
6460 any of the places it is examined, which I enumerate below. The key
6461 point to understanding each item in this enumeration is that a state
6462 with an error transition is labelled consistent in the first place only
6463 if it has no rules, so the check cannot matter for states that have
6464 rules. (1) Labelling a state as inconsistent will cause set_conflicts
6465 to try to identify its conflicts, and a state must have *rules* to have
6466 conflicts. (2) Labelling a state as inconsistent will affect how
6467 action_row sets the default *rule* for the state. (3) Labelling a
6468 state as inconsistent will cause build_relations to add lookback edges
6469 to *rules* in that state.
6470 * src/state.h (struct state): Word the comment for member consistent
6473 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
6475 Don't depend on C99 features.
6476 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
6477 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
6478 * src/reader.c (check_and_convert_grammar): Fix for-loop.
6479 * src/state.c (state_mark_reachable_states): Fix for-loop.
6480 (state_remove_unreachable_states): Fix for-loop.
6482 Don't widen struct state with member reachable just to temporarily
6483 record reachability. Instead, use a local bitset.
6484 * src/state.h (struct state): Remove member.
6485 * src/state.c (state_new): Don't initialize it.
6486 (state_mark_reachable_states): Rename to...
6487 (state_record_reachable_states): ... this, and use bitset.
6488 (state_remove_unreachable_states): Use bitset.
6490 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
6492 * src/Makefile.am (yacc): Quote target action commands properly so
6493 that the yacc script isn't corrupt. Reported by Hans Aberg at
6494 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
6496 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
6497 the case of pure parsers. Reported by Frans Englich at
6498 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
6499 * THANKS: Add Frans Englich.
6501 * NEWS (2.3a+): In the %code entry, reference section `Bison
6502 Declaration Summary' from the manual now since the %code summary has
6504 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
6505 in the rules section must be terminated by semicolons.
6507 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
6509 Extend the front-end API for %define variables to more completely
6510 mirror the back-end. This will be useful in the future.
6511 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
6512 Update comments to mention the new front-end counterparts of these
6514 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
6515 for muscle_string_decode and muscle_location_decode.
6516 (muscle_string_decode): New static function.
6517 (muscle_location_decode): Use MUSCLE_COMMON_DECODE.
6518 (muscle_percent_define_get, muscle_percent_define_ifdef): New
6520 (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and
6521 muscle_percent_define_get to mimic the b4_percent_define_flag_if
6522 implementation more closely.
6523 (muscle_percent_define_invalid_value): New function.
6524 * src/muscle_tab.h (muscle_percent_define_get,
6525 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
6528 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
6530 * NEWS (2.3a+): Mention yesterday's state-removal change.
6531 (2.3a): Remove the %language entry, which was added after 2.3a.
6532 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
6533 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
6534 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
6535 tests/existing.at: Update copyright date.
6537 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
6539 If conflict resolution makes states unreachable, remove those states,
6540 report rules that are then unused, and don't report conflicts in those
6542 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
6543 New global function.
6544 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global

6556 * tests/existing.at (GNU pic Grammar): Update test case output now that
6557 an unused rule is discovered.
6559 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
6561 Minor code cleanup in parser table construction.
6562 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
6563 (new_itemsets, save_reductions): Update for rename to nitemset.
6564 * src/closure.c (nritemset): Rename to...
6565 (nitemset): ... this since the "r" appears to meaningless and isn't
6566 used in the comments.
6567 (closure): Update for rename.
6568 * src/closure.h (nritemset): Update extern to...
6569 (nitemset): ... this.

6572 * src/print_graph.c (print_graph): Likewise.
6573 * src/state.h: Fix some typos in header comments.
6575 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
6577 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
6578 still sticks to ASCII. Sorry!
6580 * README-hacking: New file, taken mostly from coreutils, with changes

6629 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6631 DJGPP spefic issue. Inhibit the use of disallowed characters for
6632 file name genertion on Win98, WinXP, etc. These are |<>":?*\
6633 and concern testsuite case 46.

6652 %define and %code directives.
6654 Make it easy to share %define boolean variables between the front-end
6655 and back-end. Though not used yet, this will be useful in the future.
6656 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
6657 Bison uses of names rather than just skeleton uses of names.
6658 (b4_percent_define_get, b4_percent_define_ifdef): Rename

6665 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
6666 muscle_percent_define_default): New functions mimicking
6667 b4_percent_define_flag_if and b4_percent_define_default.
6669 For %define variables, report locations for invalid values and
6671 * data/bison.m4 (b4_percent_define_flag_if): Read
6672 b4_percent_define_loc(VARIABLE) to report the location of an invalid
6674 (b4_percent_define_default): Save a special location in
6675 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
6676 must later be reported as invalid.
6677 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
6679 (muscle_percent_define_insert): Record the location of VARIABLE in
6680 muscle percent_define_loc(VARIABLE), and use it to report the previous

6700 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
6702 * data/lalr1.java: Prefix all private members with yy.
6704 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
6706 Use YYFPRINTF instead of fprintf where appropriate. Reported by
6707 Sebastien Fricker at
6708 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
6709 * THANKS: Add Sebastien Fricker.
6710 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
6711 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must

6724 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
6726 Undo my 2007-02-07 change, switching back to the c-strcase module
6727 introduced in the 2007-02-03 change. Bruno Haible reported that
6728 the 2007-02-07 change would be dangerous in Turkish if we add a
6729 language whose name contains "i", since "i" is not lowercase "I"
6731 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
6732 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
6733 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
6734 * m4/.cvsignore: Remove strcase.m4.
6735 * src/getargs.c: Revert 2007-02-07 change, as follows.
6736 Include c-strcase.h.
6737 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
6739 2007-02-11 Bruno Haible <bruno@clisp.org>
6741 Enable the Java related testsuite tests when the only Java compiler
6742 found is a gcj < 4.3. Discussed at
6743 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
6744 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
6746 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
6748 * data/Makefile.am: Update copyright date.
6749 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
6750 yypstate_new returns NULL.
6751 (yypstate_new): Return NULL if malloc does.
6752 * src/reader.c (packgram): Move translation of rule actions from the
6753 beginning of packgram to...
6754 (check_and_convert_grammar): ... here right before packgram is invoked
6755 so it's easier to write more complete comments, and remove redundant
6758 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
6760 As in semantic actions, make @$ in %initial-action, %destructor, and
6761 %printer imply %locations.
6762 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
6764 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
6765 (@$ in %initial-action implies %locations,
6766 @$ in %destructor implies %locations,
6767 @$ in %printer implies %locations): ... these new test cases.
6769 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
6771 Undo most of the 2007-02-03 change, switching to the strcase module
6772 now that gnulib strcase has been fixed.
6773 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
6774 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
6775 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
6776 * m4/.cvsignore: Add strcase.m4.
6777 * src/getargs.c: Revert 2007-02-03 change, as follows.
6778 Don't include c-strcase.h.
6779 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
6780 strcasecmp has "unspecified behavior" outside the POSIX locale,
6781 but it works fine in practice if at least one argument is ASCII,
6782 as is the case in Bison.
6784 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
6786 * tests/java.at: Skip tests if only one of javac/java is present.
6787 Reported by Joel E. Denny.
6788 * tests/atlocal.in: Adjust copyright years.
6790 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
6792 * data/lalr1.java (Stack): Work around old verifiers that disallow
6793 access to the private fields of an inner class, from the outer class.
6794 We can make Stack's fields public because user code doesn't have access
6795 to the instance of Stack used by parse(). Reported by Paul Eggert.
6797 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
6799 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
6800 the right spot for these files?
6801 * bootstrap.conf (gnulib_modules): Add c-strcase.
6802 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
6804 * src/getargs.c: Include c-strcase.h.
6805 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
6806 to avoid unspecified behavior.
6808 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
6810 * doc/bison.texinfo (Decl Summary): Correct typo.
6812 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
6814 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
6815 Complain if the value does not match empty, "true" or "false".
6816 * data/c++.m4: Adjust default definitions of %define variables.
6817 * data/java.m4: Adjust default definitions of %define variables.
6818 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
6820 * tests/input.at (Boolean %define variables): Test new behavior.
6822 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
6824 * NEWS: Mention java.
6825 * TODO: Remove things that are done.
6826 * bootstrap.conf: Add javacomp-script and javaexec-script.
6827 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
6829 * data/Makefile.am: Add new files.
6830 * data/java-skel.m4: New.
6831 * data/java.m4: New.
6832 * data/lalr1.java: New.
6834 * doc/bison.texinfo: Put "A Complete C++ Example" under
6835 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
6836 under Other Languages.
6838 * src/getargs.c (valid_languages): Add Java.
6839 * src/getargs.h (struct bison_language): Update size of string fields.
6841 * tests/Makefile.am: Add java.at.
6842 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
6843 * tests/java.at: New.
6844 * tests/testsuite.at: Include it.
6846 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
6849 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
6850 at_directive_argv arguments so these no longer have to be global
6851 variables. Also, update the implementation for the following changes.
6852 (fail_for_at_directive_too_many_args,
6853 fail_for_at_directive_too_few_args): Add at_directive_name argument.
6854 (at_directive_name): Remove as at_directive_argv[0] will be used for
6856 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
6857 for the directive name.
6858 (at_directive_argc, at_directive_argv): Make these local within
6859 skel_lex instead of global.
6860 (INITIAL): Update directive start action for above changes.
6861 (SC_AT_DIRECTIVE_ARG): Rename to...
6862 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
6863 (SC_AT_DIRECTIVE_SKIP_WS): Update.
6864 (scan_skel): Move yylex_destroy to...
6865 (skel_scanner_free): ... here.
6866 * tests/skeletons.at (installed skeleton file name): Rename to...
6867 (installed skeleton file names): ... this.
6869 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
6871 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
6872 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
6873 Summary" not "Directives".
6874 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
6875 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
6876 since the former is now the more complete one.
6877 (Prologue Alternatives): Likewise and do the same for %defines.
6878 (Table of Symbols): Add summary of %code, add summary of %define, and
6879 move full %code documentation to...
6880 (Decl Summary): ... here for consistency with other entries in these
6882 Move %define entry in order to keep this list alphabetized.
6883 Reword %define entry a little to put less emphasis on the skeleton
6884 concept, which most users shouldn't have to think about.
6886 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
6888 Adjust to recent gnulib changes.
6889 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
6890 Add string.h, string_.h, unistd_.h, wchar_.h.
6891 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
6892 * src/system.h: Don't include <stpcpy.h>; this is now done by
6895 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
6897 Simplify implementation of unqualified %code, implement macros for
6898 uniform treatment of boolean %define flags. Document %define.
6899 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
6900 b4_percent_code_ifdef): New.
6901 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
6902 * data/c++.m4: Define default value for global_tokens_and_yystype.
6903 * data/glr.cc: Likewise.
6904 * data/location.cc: Use b4_percent_define_flag_if.
6906 * doc/bison.texinfo (Decl Summary): Document %define.
6908 * src/parse-gram.y (Unqualified %code): Change muscle name to
6910 (content.opt): Default to empty.
6912 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
6914 Implement support for relative and absolute skeleton file names.
6915 Discussed starting at
6916 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
6917 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
6918 (Bison Options): Document in --skeleton entry.
6919 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
6920 full_skeleton can't necessarily hold all of pkgdatadir.
6921 If the specified skeleton file name contains a `/', don't prepend
6923 * src/parse-gram.y (prologue_declaration): If the specified skeleton
6924 file name contains a `/', prepend the grammar file directory.
6925 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
6926 * skeletons.at: New file.
6927 (relative skeleton file names): New test case.
6928 (installed skeleton file names): New test case.
6929 * tests/testsuite.at: Include skeletons.at.
6931 * bootstrap: Update copyright to 2007.
6933 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
6935 * bootstrap: Remove occurrences of .#bootmp from the files.
6937 2007-01-17 Akim Demaille <akim@epita.fr>
6939 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
6941 Use per-type %printer.
6943 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
6945 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

6953 2007-01-16 Akim Demaille <akim@epita.fr>
6955 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
6957 (Calc++ Scanner): Exit with failure if we can't open the input
6959 Accept "-" standing for stdin.
6960 (Calc++ Top Level): Print the result only if the parsing was
6963 2007-01-16 Akim Demaille <akim@epita.fr>
6965 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
6967 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
6968 and Joel E. Denny <jdenny@ces.clemson.edu>
6970 Clean up %define and %code implementation in M4 some. Most
6971 importantly, rename all related macros to be in the b4_percent_define
6972 and b4_percent_code namespaces. Also, complete support for `.' in
6973 %define variable names and %code qualifiers.
6974 * data/bison.m4 (b4_check_user_names): Check for special
6975 "SKELETON-NAMESPACE(name)" macros instead of using two nested
6977 (b4_get_percent_define, b4_get_percent_code): Rename to...
6978 (b4_percent_define_get, b4_percent_code_get): ... these.
6979 Extend documentation with examples.
6980 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
6981 b4_percent_define_skeleton_variables and
6982 b4_percent_code_skeleton_qualifiers.
6983 Expect any value for the %define variable `foo' to be stored in the
6984 macro named `b4_percent_define(foo)'; expect any %code blocks for the
6985 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
6986 expect any unqualified %code blocks to be stored in a macro named
6987 `b4_percent_code_unqualified'.
6988 Use m4_indir so that %define variable names and %code qualifiers can
6989 contain `.', which is allowed by the grammar parser.
6990 (b4_percent_define_default): New macro to set a default value for a
6992 (m4_wrap): Update wrapped code, and fix some underquoting.
6993 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
6994 Expect grammar uses of %define variables and %code qualifiers to be
6995 defined in b4_percent_define_user_variables and
6996 b4_percent_code_user_qualifiers.
6997 * data/c++.m4: Use b4_percent_define_default rather than
6998 m4_define_default. Fix some underquoting. Skeleton usage of %define
6999 variable define_location_comparison now implies skeleton usage of
7000 %define variable filename_type.
7001 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7002 data/push.c, data/yacc.c: Update macro names.
7003 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
7006 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
7008 DJGPP specific issues.
7010 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
7011 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
7013 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7015 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
7016 run parsers in all tests so that Valgrind is invoked during
7017 maintainer-check-valgrind.
7018 (Duplicate representation of merged trees): Free all semantic values.
7019 (Duplicated user destructor for lookahead): Likewise.
7021 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7023 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
7024 command-line prefix.
7025 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
7026 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
7027 miss Valgrind messages.
7028 (Exploding the Stack Size with Malloc): Likewise.
7030 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
7032 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
7033 locals. Reported by Juan Manuel Guerrero at
7034 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
7035 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
7036 Fix some indentation also.
7037 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
7038 explaining this issue.
7040 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
7041 and Joel E. Denny <jdenny@ces.clemson.edu>
7043 Simplify union and prologue handling, and escape union and lex/parse
7044 params with digraphs.
7045 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
7046 values to the empty string since these are no longer guaranteed
7047 initialized by the front-end.
7048 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
7049 braces around b4_user_stype since this is no longer done by the
7051 * src/files.c, src/files.h (pre_prologue_obstack,
7052 post_prologue_obstack): Remove.
7053 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
7054 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
7055 with digraphs. This fixes lex params and parse params.
7056 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
7057 * src/output.c (prepare): Remove muscle insertion of the prologues.
7058 (output): Remove freeing of pre_prologue_obstack and
7059 post_prologue_obstack.
7060 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
7061 than prologue_augment for prologue parsing so you don't need prologue
7063 (grammar_declaration): For %union RHS, use `braceless' instead of
7064 "{...}" so that braces are already stripped and code is escaped with
7066 * src/reader.c (prologue_augment): Remove.
7067 (reader): Remove initialization of pre_prologue_obstack and
7068 post_prologue_obstack.
7069 * src/reader.h (prologue_augment): Remove.
7071 * data/c.m4: Remove stray parenthesis.
7073 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7075 Remove quotes from variables names in %define directives and from
7076 qualifiers in %code directives, and restrict the characters that are
7077 allowed in them to M4-friendly ones. For %define, continue to support
7078 the quoted form as a deprecated feature. Discussed starting at
7079 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
7080 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
7082 * doc/bison.texinfo (Prologue Alternatives): Update.
7083 (Decl Summary): In %defines entry, update mention of `%code requires'
7084 and `%code provides'.
7085 (C++ Location Values): Update %define uses.
7086 (Calc++ Parser Interface): Likewise.
7087 (Calc++ Parser): Likewise, and update `%code requires' uses.
7088 (Table of Symbols): Update %code documentation.
7089 * src/parse-gram.y (prologue_declaration): For %define variables, use
7090 `variable' instead of `STRING'.
7091 (grammar_declaration): For %code qualifiers, use `ID' instead of
7093 (variable): New nonterminal that takes an `ID' or a `STRING'.
7094 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
7096 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
7097 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
7098 (%define errors): Update %define uses.
7100 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7102 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
7103 instead of muscle_insert for %define values so that M4-special
7104 characters are replaced with digraphs.
7105 * tests/input.at (%define errors): Extend to check weird values.
7107 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
7109 Instead of having skeletons declare all valid %define variables and
7110 %code qualifiers, provide macros that retrieve the associated values
7111 and build these lists automatically. Thus Bison will now warn when a
7112 variable or qualifier is not used by the skeleton in the current
7113 invocation regardless of whether it might sometimes be used by that
7114 skeleton in other invocations. Also, move all %define value macros to
7115 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
7116 form, which is replaced by %code.
7117 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
7118 (b4_check_user_names): ... this, and change the series of valid name
7119 arguments to a single list argument for names used in the skeleton
7120 similar to the existing list argument for names used in the grammar.
7121 Warn instead of complaining.
7122 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
7123 values and %code code, to format %code code properly, and to build
7124 lists of all %define variables and %code qualifiers used in the
7125 skeleton: b4_skeleton_percent_define_variables and
7126 b4_skeleton_percent_code_qualifiers.
7127 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
7129 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
7130 the skeleton names lists can finish building first. In place of
7131 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
7132 expect the lists b4_user_percent_define_variables and
7133 b4_user_percent_code_qualifiers.
7134 * data/c++.m4: Where setting default values for b4_parser_class_name,
7135 b4_location_type, b4_filename_type, b4_namespace, and
7136 b4_define_location_comparison, update their names to the
7137 b4_percent_define_ namespace.
7138 * data/glr.c: Don't use b4_check_percent_define_variables and
7139 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7140 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
7141 (b4_parser_class_name, b4_namespace): Define these using
7142 b4_get_percent_define for parser_class_name and namespace.
7143 * data/location.cc: Use b4_get_percent_define.
7144 * data/push.c: Don't use b4_check_percent_define_variables and
7145 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
7146 * data/yacc.c: Likewise, and don't call m4_exit in
7147 b4_use_push_for_pull_if or m4_wrap code will never execute.
7148 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
7150 (muscle_grow_user_name_list): ... this for consistency with the
7151 terminology used in bison.m4.
7152 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
7153 %define variable names, and rename muscle used_percent_define_variables
7154 to user_percent_define_variables.
7155 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
7156 user_percent_code_qualifiers.
7158 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
7159 {CODE} form is no longer accepted.
7160 * tests/input.at (Reject bad %code qualifiers): Rename to...
7161 (Reject unused %code qualifiers): ... this, and update test output.
7162 (%define error): Update test output.
7164 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
7166 Check for unrecognized %define variables similar to checking for
7167 unrecognized %code qualifiers. Check for redefined %define variables.
7168 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
7170 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
7171 (b4_check_percent_define_variables): New, also wraps it.
7172 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
7173 variables using b4_check_percent_define_variables.
7174 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
7175 all those exercised in the test suite and all those listed in the
7176 `Default values' section of c++.m4. Are there others?
7177 * data/push.c, data/yacc.c: Declare no valid %define variables.
7178 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
7179 similar to muscle_find, but it works even when the muscle stores a
7181 (muscle_grow_used_name_list): New function for constructing the used
7182 name list muscles that b4_check_for_unrecognized_names requires.
7183 * src/parse-gram.y (prologue_declaration): Warn if a variable is
7184 %define'd more than once. Define the b4_used_percent_define_variables
7185 muscle with muscle_grow_used_name_list.
7186 (grammar_declaration): Abbreviate %code code with
7187 muscle_grow_used_name_list.
7188 * tests/input.at (%define errors): New.
7190 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7192 Provide warn_at, complain_at, and fatal_at function callbacks to the
7193 skeletons, and use this for %code qualifier complaints.
7194 * data/bison.m4 (b4_error_at): New, invoked by...
7195 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
7196 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
7197 @fatal_at(...@) directives.
7198 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
7199 qualifiers in b4_used_percent_code_qualifiers and to use
7201 * src/location.c, src/location.h (boundary_set_from_string): New global
7203 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
7205 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
7206 to b4_used_percent_code_qualifiers.
7207 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
7209 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
7210 (lineno): Rename to...
7211 (out_lineno): ... this so I don't misunderstand it again.
7212 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
7213 here; these newlines are in the input but not the output file.
7214 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
7215 (at_directive_perform): ... this new static function, and add handling
7216 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
7218 * tests/input.at (Reject bad %code qualifiers): Update test output with
7219 locations and extend.
7221 * tests/output.at (Output file name: [, Output file name: ]): Remove
7222 bogus comment about these tests failing.
7224 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
7226 Clean up b4_check_percent_code_qualifiers a little.
7227 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
7228 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
7229 documentation and add examples.
7230 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
7233 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7235 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
7236 unreliable -- especially when they're hidden inside another macro.
7237 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
7238 data/c.m4: Remove m4_divert(-1).
7239 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
7240 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
7241 m4_divert_push(0) and m4_divert_pop(0).
7242 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
7243 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
7244 pushed and popped by m4sugar, should be first on the stack.
7246 Provide warn, complain, and fatal function callbacks to the skeletons.
7247 This provides more flexibility than m4_fatal, improves the error
7248 message format, and captures messages for translation. Discussed
7250 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
7251 * data/bison.m4 (b4_error): New, invoked by...
7252 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
7253 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
7254 directives. Because these M4 macros might be called when the current
7255 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
7256 the previous removal of uses of m4_divert, which caused trouble.
7257 (b4_check_percent_code_qualifiers): Use b4_complain instead of
7258 m4_fatal to report unrecognized %code qualifiers.
7259 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
7260 push parser requests.
7261 * data/glr.c: Use b4_complain instead of m4_fatal to report
7262 non-deterministic push parser requests.
7263 Update @output usage to @output(...@) form.
7264 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
7265 report missing %defines. Update @output usage to @output(...@) form.
7266 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
7268 * src/main.c (main): Invoke skel_scanner_free.
7269 * src/scan-skel.h (skel_scanner_free): Prototype new function.
7270 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
7271 obstack_for_string from flex-scanner.h.
7272 (YY_DECL): Use to declare skel_lex static.
7273 (decode_at_digraphs): Remove; now handled in the new
7274 SC_AT_DIRECTIVE_ARG start condition.
7275 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
7277 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
7278 at_directive_argv): New static globals.
7279 (INITIAL): Use fail_for_invalid_at.
7280 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
7281 recognize the start of a generalized `@directive(...@)' form and
7283 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
7284 directive args (using the new obstack_for_string), to decode the
7285 contained @ diagraphs, and to perform the directive. It recognizes
7286 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
7288 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
7289 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
7291 (scan_skel): Initialize obstack_for_string on the first call.
7292 (skel_scanner_free): New function to free obstack_for_string.
7293 * tests/input.at (Reject bad %code qualifiers): Update test output.
7295 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
7297 Consolidate the 4 prologue alternative directives (%code, %requires,
7298 %provides, and %code-top) into a single %code directive with an
7299 optional qualifier field. Discussed at
7300 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
7301 * NEWS (2.3a+): Rewrite the existing entry for the prologue
7303 * doc/bison.texinfo (Prologue Alternatives): Update.
7304 (Decl Summary): Update to %code "requires" and %code "provides".
7305 (Calc++ Parser): Update to %code "requires".
7306 (Table of Symbols): Remove entries for %requires, %provides, and
7307 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
7308 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
7309 are replaced by b4_percent_code_provides and b4_percent_code_requires,
7310 which are skeleton-specific.
7311 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
7312 declare what %code qualifiers it supports and to complain if any other
7313 qualifiers were used in the grammar.
7314 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
7315 and b4_user_code([b4_percent_code_provides]) in place of
7316 b4_user_requires and b4_user_provides.
7317 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
7318 Add b4_user_code([b4_percent_code_top]) and
7319 b4_user_code([b4_percent_code]).
7320 Invoke b4_check_percent_code_qualifiers.
7321 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7322 PERCENT_REQUIRES): Remove.
7323 (grammar_declaration): Remove RHS's for %code-top, %provides, and
7324 %requires. Rewrite the %code RHS as the unqualified form defining the
7325 muscle b4_percent_code. Add another RHS for the qualified %code form,
7326 which defines muscles of the form b4_percent_code_QUALIFIER and the
7327 b4_used_percent_code_qualifiers muscle.
7328 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
7329 PERCENT_REQUIRES): Remove.
7330 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
7331 %code "requires" and %code "provides".
7332 * tests/input.at (Reject bad %code qualifiers): New.
7334 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7336 Use the new code_props interface for destructors and printers.
7337 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
7338 printer_location members, and change the type of the destructor and
7339 printer members to code_props.
7340 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
7341 symbol_printer_get, semantic_type_destructor_set,
7342 semantic_type_printer_set, default_tagged_destructor_set,
7343 default_tagless_destructor_set, default_tagged_printer_set,
7344 default_tagless_printer_set): Use code_props in arguments and return
7345 types in place of char const * and location.
7346 (symbol_destructor_location_get, symbol_printer_location_get): Remove
7347 since the locations are now contained in the return of
7348 symbol_destructor_get and symbol_printer_get.
7349 * src/output.c (symbol_destructors_output, symbol_printers_output):
7351 (symbol_code_props_output): ... this to eliminate duplicate code.
7352 (output_skeleton): Update to use symbol_code_props_output.
7353 * src/reader.c (symbol_should_be_used): Update use of
7354 symbol_destructor_get.
7355 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
7356 Update uses of the various _destructor_set and _printer_set functions.
7357 * src/symtab.c: (default_tagged_destructor_location,
7358 default_tagless_destructor_location, default_tagged_printer_location,
7359 default_tagless_printer_location): Remove since we...
7360 (default_tagged_destructor, default_tagless_destructor,
7361 default_tagged_printer, default_tagless_printer): ... change the type
7362 of these to code_props.
7363 (symbol_new, semantic_type_new, symbol_destructor_set,
7364 semantic_type_destructor_set, symbol_destructor_get,
7365 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
7366 symbol_check_alias_consistency, default_tagged_destructor_set,
7367 default_tagless_destructor_set, default_tagged_printer_set,
7368 default_tagless_printer_set): Update.
7369 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
7370 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
7372 (symbol_print): Use SYMBOL_CODE_PRINT.
7374 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
7376 Use the new code_props interface for rule actions.
7377 * src/symlist.h (symbol_list): Replace action, action_location, and
7378 used members with a code_props action_props member.
7379 * src/reader.c (symbol_should_be_used, grammar_rule_check,
7380 grammar_midrule_action, grammar_current_rule_merge_set,
7381 grammar_current_rule_symbol_append, packgram): Update.
7382 * src/scan-code.h (translate_rule_action): Remove, no longer used.
7383 * src/scan-code.l (handle_action_dollar): Update.
7384 (translate_rule_action): Remove, no longer used.
7385 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
7387 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7389 Use the new code_props interface in parse-gram.y.
7390 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
7391 Update all uses of translate_* functions to use the new code_props
7392 interface and to use gram_scanner_last_string_free and
7393 code_scanner_last_string_free where possible.
7394 (grammar_declaration): symbol_list_destructor_set and
7395 symbol_list_printer_set now perform the translation, so don't do it
7396 here. Use gram_scanner_last_string_free where possible.
7397 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
7398 translate_code): Remove, no longer used.
7399 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
7400 symbol_list_printer_set): Perform code translation here rather than
7401 depending on the caller to do so.
7403 * src/symlist.h (struct symbol_list): Correct some documentation typos.
7404 * src/scan-gram.h (gram_last_string): Remove declaration.
7405 * src/scan-gram.l (last_string): Declare it static.
7407 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
7409 Encapsulate code properties and related functionality for the various
7410 destructors, printers, and actions into a code_props structure and
7411 interface. This patch merely implements code_props in scan-code.h and
7412 scan-code.l. Future patches will rewrite other modules to use it.
7413 Discussed starting at
7414 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
7415 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
7416 consistently initialize const structs that have an empty location
7418 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
7419 to ensure consistency.
7420 * src/scan-code.h (code_props): New structure.
7421 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
7422 function, macro, and const global variable for initializing a
7423 code_props with no code.
7424 (code_props_plain_init, code_props_symbol_action_init,
7425 code_props_rule_action_init, code_props_translate_code): The rest of
7426 the new code_props functional interface. Among other things, the init
7427 functions set the code_props kind field so that
7428 code_props_translate_code will know whether to behave like
7429 translate_symbol_action, translate_rule_action, or translate_code.
7430 These old translate functions must remain until all other modules are
7431 updated to use the new code_props interface.
7432 (code_scanner_last_string_free): New function similar to
7433 gram_scanner_last_string_free.
7434 (code_scanner_free): Add documentation.
7435 * src/scan-code.l: Implement the new interface.
7436 (code_lex): Make it static, add a code_props* argument, and remove the
7438 (last_string): New static global similar to the one in scan-gram.l.
7439 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
7441 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
7442 code_props since Bison may one day use this information for destructors
7444 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
7445 (handle_action_dollar): Use symbol_list_n_get and set used flag
7446 directly since symbol_list_n_used_set is removed.
7447 (translate_action): Add a code_props* argument and remove the rule,
7448 action, and location arguments. Pass the code_props* on to code_lex.
7449 (translate_rule_action, translate_symbol_action, translate_code):
7450 Rewrite as wrappers around the new code_props interface.
7451 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
7452 it would eventually need to break the encapsulation of code_props.
7454 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7456 * etc/.cvsignore: New.
7458 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
7460 Add maintainer-push-check to run maintainer-check using push parsing in
7461 place of pull parsing where available.
7462 * Makefile.am (maintainer-push-check): New.
7463 * data/bison.m4 (b4_use_push_for_pull_if): New.
7464 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
7465 appropriately based on their existing values.
7466 (yypush_parse): Don't print push-parser-specific diagnostics if push
7467 parsing is being used in place of pull parsing.
7468 * data/yacc.c: If push parsing should replace pull parsing, redirect to
7470 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
7471 variable, and insert b4_use_push_for_pull_flag into muscles.
7472 * tests/Makefile.am (maintainer-push-check): New.
7474 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
7476 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
7477 (whether successful or failed) so that yypush_parse can be invoked
7478 again to start a new parse using the same yypstate.
7479 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
7480 check multiple yypull_parse invocations on the same yypstate. For pull
7481 mode, extend to check multiple yyparse invocations.
7482 (Exploding the Stack Size with Alloca): Extend to try with
7484 (Exploding the Stack Size with Malloc): Likewise.
7486 * tests/calc.at (Simple LALR Calculator): Don't specify
7487 %skeleton "push.c" since %push-pull-parser implies that now.
7488 * tests/headers.at (export YYLTYPE): Don't check for the push
7489 declarations. Otherwise, this test case can't be used to see if push
7490 mode can truly emulate pull mode.
7491 * tests/input.at (Torturing the Scanner): Likewise.
7492 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
7493 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
7494 AT_YACC_IF, which now includes the case of push mode since %skeleton
7495 need not be used for push mode. This will be more intuitive once
7496 push.c is renamed to yacc.c.
7498 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
7500 For push mode, convert yyparse from a macro to a function, invoke yylex
7501 instead of passing a yylexp argument to yypull_parse, and don't
7502 generate yypull_parse or yyparse unless %push-pull-parser is declared.
7503 Discussed starting at
7504 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
7505 * data/bison.m4 (b4_pull_if): New.
7506 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
7507 * data/push.c: Improve M4 quoting a little.
7508 (b4_generate_macro_args, b4_parenthesize): Remove.
7509 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
7510 any time a pull parser is requested.
7511 Don't #define this as a wrapper around yypull_parse. Instead, when
7512 both push and pull are requested, make it a function that does that
7514 (yypull_parse): If there's a b4_prefix, #define this to
7515 b4_prefix[pull_parse] when both push and pull are requested.
7516 Don't define this as a function unless both push and pull are
7518 Remove the yylexp argument and hard-code yylex invocation instead.
7519 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
7521 * src/getargs.c (pull_parser): New global initialized to true.
7522 * getargs.h (pull_parser): extern it.
7523 * src/output.c (prepare): Insert pull_flag muscle.
7524 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
7525 (prologue_declaration): Set both push_parser and pull_parser = true for
7526 %push-pull-parser. Set push_parser = true and pull_parser = false for
7528 * src/scan-gram.l: Don't accept %push_parser as an alternative to
7529 %push-parser since there's no backward-compatibility concern here.
7530 Scan %push-pull-parser.
7531 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
7532 instead of %push-parser.
7533 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
7534 prototype it in the module that calls yyparse.
7535 * tests/input.at (Torturing the Scanner): Likewise.
7536 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
7538 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
7540 Update etc/bench.pl. Optimize push mode a little (the yyn change
7541 deserves most of the credit).
7542 * Makefile.am (SUBDIRS): Add etc subdirectory.
7543 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
7544 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
7545 yytoken, yyval, and yyloc declarations to...
7546 (yyparse or yypush_parse): ... here to improve performance. For
7547 yypush_parse invocations after the first, be sure to assign yyn its old
7549 (yypstate_new): Don't bother initializing the yyresult field since the
7550 initial value isn't used.
7551 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
7552 remove the #define that, in push mode, set it to yyps->NAME.
7553 * etc/Makefile.am: New.
7554 * etc/bench.pl: Remove and build it instead from...
7555 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
7556 "tests/bison" from the build directory by default rather than just
7557 invoking "bison" from $PATH.
7558 (calc_grammar): Update push parser code: don't declare yylval globally,
7559 don't define yyparse_wrapper, and don't #define yyparse.
7560 (bench_grammar): Update to check all working combinations of yacc.c,
7561 push.c, impure, pure, pull, and push.
7563 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
7565 For push mode, add pull wrappers around yypush_parse.
7566 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
7567 (yypull_parse): New function wrapping yypush_parse.
7568 (yyparse): New #define wrapping yypull_parse.
7569 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
7571 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
7572 prototype yylex in the module that calls yyparse, and don't prototype
7573 yyparse there. Otherwise, the yyparse expansion won't compile.
7574 * tests/input.at (Torturing the Scanner): Likewise.
7576 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
7578 Enable push parsers to operate in impure mode. Thus, %push-parser no
7579 longer implies %pure-parser. The point of this change is to move
7580 towards being able to test the push parser code by running the entire
7581 test suite as if %push-parser had been declared.
7582 * data/push.c (yypush_parse): For impure mode, remove the
7583 yypushed_char, yypushed_val, and yypushed_loc arguments.
7584 Instead, declare these as local variables initialized to the global
7585 yychar, yylval, and yylloc.
7586 For the first yypush_parse invocation only, restore the initial values
7587 of these global variables when it's time to read a token since they
7588 have been overwritten.
7589 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
7591 * tests/calc.at (Simple LALR(1) Calculator): Always declare
7592 %pure-parser along with %push-parser since this test case was designed
7593 for pure push parsers.
7594 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
7595 (AT_YACC_OR_PUSH_IF): New.
7596 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
7597 add a note that it's still wrong for some cases (as it has been for a
7599 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
7600 %push-parser no longer implies %pure-parser.
7602 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7604 Remove some unnecessary differences between the pull parser code and
7605 the push parser code. This patch enables yynerrs in push mode.
7606 * data/push.c: Reformat M4 a little.
7607 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
7608 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
7609 because push mode is on. Instead, if pure mode is on, move yynerrs
7611 (b4_declare_parser_state_variables): ... here.
7612 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
7613 to yyps->NAME so it can be used in yypush_parse.
7614 (yypush_parse): Don't omit uses of yynerrs in push mode.
7616 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7618 Fix bug such that the first pushed token's value and location are
7619 sometimes overwritten (sometimes by %initial-action) before being used.
7620 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
7621 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
7622 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
7623 more closely mimic the pull parser logic.
7624 Don't copy the pushed token to yychar, yylval, and yylloc until it's
7625 time to read a token, which is after any initialization of yylval and
7627 (gottoken): Rename label to...
7628 (yyread_pushed_token): ... for clarity and to avoid infringing on the
7631 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
7633 Rearrange initialization of the parser state variables so that the
7634 skeleton doesn't have to have a copy for pull mode and another for push
7635 mode. This patch also fixes at least a bug such that yylloc was not
7636 initialized (with b4_location_initial_line and
7637 b4_location_initial_column) upon calling yypush_parse. However, that
7638 initialization now overwrites the first token's location;
7639 %initial-action assigning @$ already did the same thing, and both bugs
7640 will be fixed in a later patch.
7641 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
7642 (b4_declare_parser_state_variables): Remove initialization of yytoken,
7643 yyss, yyvs, yyls, and yystacksize.
7644 (yypstate_new): Remove initialization of some yypstate fields: yystate,
7645 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
7647 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
7648 yyps->NAME so it can be used in yypush_parse.
7649 (yyparse or yypush_parse): For yypush_parse, don't print the
7650 "Starting parse" diagnostic for invocations after the first.
7651 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
7652 yypush_parse, only do it for the first invocation.
7653 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
7654 initialization to occur in yypush_parse but only on the first
7657 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7659 * data/push.c: Add CPP guards around push parser declarations in both
7660 the header and the code file.
7661 In the code file, move the push parser declarations to the same place
7662 they appear in the header file.
7663 Clean up the M4 some, especially the inconsistent underquoting in
7664 some b4_c_function_def and b4_c_function_decl uses.
7666 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7668 Encapsulate the push parser state variables into an M4 macro so the
7669 push skeleton doesn't have to list them again for pull mode's yyparse.
7670 For push mode, remove yypush_parse's local equivalents of these
7671 variables to eliminate unnecessary copying between the two sets at
7672 run-time. This patch also fixes at least a bug related to multiple
7673 %initial-action invocations in push mode.
7674 * data/push.c (b4_declare_parser_variables): Rename to...
7675 (b4_declare_scanner_communication_variables): ... this for clarity and
7677 (b4_declare_yyparse_variables): Remove and move its contents to the one
7678 spot where it was invoked.
7679 (b4_declare_parser_state_variables): New macro containing the parser
7680 state variables required by push mode.
7681 (struct yypstate): Replace all fields but yynew with
7682 b4_declare_parser_state_variables.
7683 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
7684 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
7685 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
7686 (yyparse or yypush_parse): For yyparse in pull mode, replace local
7687 parser state variable declarations with
7688 b4_declare_parser_state_variables.
7689 Don't initialize parser state variables when calling yypush_parse since
7690 yypstate_new already does that.
7691 Invoke the user's initial action only upon the first yypush_parse
7693 Remove all code that copies between the local parser state variables
7696 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
7698 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
7699 prevent a name collision in a future patch where these names will
7700 sometimes be #define'd.
7701 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
7702 since it no longer has the same name as the existing argument.
7703 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
7705 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
7706 and Joel E. Denny <jdenny@ces.clemson.edu>
7708 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
7709 that the argument is case-insensitive, and there's no `=' here.
7710 For the %skeleton entry, mention that %language is better.
7711 (Bison Options): Likewise for --language and --skeleton. Move the
7712 --skeleton entry so that the `Tuning the parser' section is sorted
7713 alphabetically on long options.
7714 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
7715 %language directive in detail here; cross-reference the %language
7716 documentation instead.
7717 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
7718 `%require "2.3b"' so that the example is always up-to-date.
7719 (Table of Symbols): Add entries for %language and %skeleton.
7720 * examples/extexi (normalize): Instead of replacing every %require
7721 argument with the current Bison version, just substitute for
7722 `@value{VERSION}'. This guarantees that we're testing what actually
7723 appears in the documentation.
7724 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
7725 rather than `@VERSION@'.
7727 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7729 * NEWS: Reword the %language news a bit, and put it earlier.
7731 * src/getargs.c (skeleton_arg): Last arg is now location const *.
7732 Rewrite to simplify the logic.
7733 (language_argmatch): Likewise.
7734 (program_name): We now own this var.
7735 * src/getargs.h (struct bison_language): Use char[] rather than
7738 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
7740 * src/complain.c (program_name): Remove decl; no longer needed.
7741 * src/main.c (program_name): Remove; now belongs to getargs.
7743 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
7745 * NEWS: Document %language.
7747 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
7749 * data/c-skel.m4, data/c++-skel.m4: New files.
7750 * data/glr.c: Complain on push parsers.
7752 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
7754 (Decl Summary): Document %language and %skeleton.
7755 (Command line): Document -L.
7757 * examples/extexi: Rewrite %require directive.
7758 * examples/calc++/Makefile.am: Pass VERSION to extexi.
7760 * src/files.c (compute_exts_from_gc): Look in language structure
7762 (compute_file_name_parts): Check whether .tab should be added.
7763 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
7764 (language, skeleton_arg, language_argmatch): New.
7765 (long_options): Add --language.
7766 (getargs): Use skeleton_arg, add -L/--language.
7767 * src/getargs.h: Include location.h.
7768 (struct bison_language, language, skeleton_arg, language_argmatch): New.
7769 * src/output.c (prepare): Pick default skeleton from struct language.
7770 Don't dispatch C skeletons here.
7771 * src/parse-gram.y (PERCENT_LANGUAGE): New.
7772 (prologue_declaration): Add "%language" rule, use skeleton_arg.
7773 * src/scan-gram.l ("%language"): New rule.
7775 * tests/calc.at: Test %skeleton and %language.
7776 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
7777 (AT_GLR_IF): Look for %skeleton "glr.cc".
7778 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
7779 (AT_YACC_IF): Reject %language.
7781 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7783 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
7784 since it wasn't used; only the typedef name 'semantic_type' is needed.
7785 Also, omit trailing white space.
7787 * bootstrap: Sync from coreutils.
7788 (gnulib_extra_files): Add build-aux/announce.gen.
7789 (slurp): Adjust .gitignore files like .cvsignore files.
7790 * build-aux/announce-gen: Remove from CVS, since bootstrap
7793 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
7795 Make %push-parser imply %pure-parser. This fixes several bugs; see
7796 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
7797 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
7799 * data/push.c: Don't bother testing b4_push_if when deciding whether
7800 to expand b4_declare_parser_variables globally.
7801 (yypush_parse): Likewise in here.
7803 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
7804 (yy_reduce_print): Reformat M4 for readability.
7806 2006-12-15 Bob Rossi <bob@brasko.net>
7807 and Joel Denny <jdenny@ces.clemson.edu>
7809 * data/push.c (yypstate): Add typedef, and update all uses of
7810 struct yypstate to just yypstate.
7811 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
7813 2006-12-14 Bob Rossi <bob@brasko.net>
7815 * data/push.c (yypush_parse): Declare prototype regardless of
7818 2006-12-14 Bob Rossi <bob@brasko.net>
7820 * data/push.c (yyparse): Remove the prototype and the #define when in
7823 2006-12-13 Bob Rossi <bob@brasko.net>
7825 * data/push.c (yypstate_init): Rename to...
7826 (yypstate_new): ... this and use b4_c_function_def.
7827 (yypstate_delete): New.
7828 (yypush_parse): Change parameters yynval and yynlloc to be const.
7829 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
7830 yypstate_delete functions.
7832 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
7834 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
7835 strange test case titles. Reported by Bob Rossi.
7837 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
7839 * TODO: Add pointer to Sylvain Schmitz's work on static detection
7840 of potential ambiguities in GLR grammers.
7842 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
7844 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
7845 `bison ', use m4_index instead of m4_substr since chopping up a string
7846 containing M4-special characters causes problems here.
7848 Fix a couple of bugs related to special characters in user-specified
7849 file names, and make it easier for skeletons to compute output file
7850 names with the same file name prefix as Bison-computed output file
7852 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
7853 b4_parser_file_name and b4_spec_defines_file instead of
7854 @output_parser_name@ and @output_header_name@, which are now redundant.
7855 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
7856 b4_parser_file_name, b4_spec_defines_file, and the new
7857 @basename(FILENAME@) instead of @output_parser_name@ and
7858 @output_header_name@, which inappropriately escaped the file names as
7860 * src/files.c (all_but_ext): Remove static qualifier.
7861 (compute_output_file_names): Move `free (all_but_ext)' to...
7862 (output_file_names_free): ... here since all_but_ext is needed later.
7863 * src/files.h (all_but_ext): Extern.
7864 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
7865 exactly what MUSCLE_INSERT_STRING used to do.
7866 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
7867 characters are escaped properly.
7868 * src/output.c (prepare): Define muscle file_name_all_but_ext as
7870 For pkgdatadir muscle, maintain previous functionality by using
7871 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
7872 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
7873 digraphs would never be expanded. Hopefully no one has M4-special
7874 characters in his Bison installation path.
7875 * src/scan-skel.l: Don't parse @output_header_name@ and
7876 @output_parser_name@ anymore since they're now redundant.

7888 * data/glr.c: Don't generate the header file here when glr.cc does.
7889 * src/files.c (file_names, file_names_count): New static globals.
7890 (compute_output_file_names): Invoke output_file_name_check for files
7891 not generated by the skeletons and remove existing checks.
7892 (output_file_name_check): New function that warns about conflicting
7894 (output_file_names_free): Free file_names.

7920 * data/push.c (yypvarsinit): Change return type from void* to struct
7921 yypvars*. No longer cast to void* on return.
7922 (struct yypvars): Remove yylen since it need not be remembered between
7923 yypushparse invocations.
7924 (yypushparse): Don't copy between yylen and pv->yylen.
7926 2006-12-05 Bob Rossi <bob@brasko.net>

8028 later. Reported by Paul Eggert in
8029 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
8030 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
8031 * src/scan-code.l (translate_action): Don't bother invoking
8032 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
8033 (code_scanner_free): Instead of invoking

8042 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
8043 has been called previously for the same key.
8044 (muscle_find): Return storage instead of value so that
8045 --enable-gcc-warnings doesn't produce warnings that the return discards
8046 const. aver that the value and storage are the same since storage
8047 could potentially be NULL when value is not.
8048 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
8051 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8053 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
8054 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives

8093 add a new `char *code' member.
8094 ("{...}"): Declare semantic type as code.
8095 * src/scan-code.h (translate_rule_action):
8096 (translate_symbol_action, translate_code, translate_action): Return
8097 `char const *' rather than `char *' since external code should not free
8099 * src/scan-code.l: Likewise.
8100 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
8101 which is "{...}" in the parser.

8107 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
8108 expecting a non-zero exit status sets --leak-check=summary and
8109 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
8110 this case, and we don't want to hear about it.
8112 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8114 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
8115 instead of from the template, to simplify configuration a bit.

8159 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
8160 the parser header file so that gcc doesn't warn.
8162 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

8212 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
8213 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
8214 like $@n instead of just @n so that the default %destructor/%printer
8215 logic doesn't see them as user-defined symbols.
8216 (symbol_is_dummy): Check for both forms of the name.
8217 * src/reader.c (packgram): Remove the `$' from each midrule symbol

8317 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
8318 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
8319 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
8320 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
8321 * test/regression.at (Diagnostic that expects two alternatives):
8324 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8326 * bootstrap.conf (gnulib_modules): Add config-h.
8327 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
8328 worry about HAVE_CONFIG_H.
8329 * lib/abitset.c: Likewise.
8330 * lib/bitset.c: Likewise.
8331 * lib/bitset_stats.c: Likewise.
8332 * lib/bitsetv-print.c: Likewise.
8333 * lib/bitsetv.c: Likewise.
8334 * lib/ebitset.c: Likewise.
8335 * lib/get-errno.c: Likewise.
8336 * lib/lbitset.c: Likewise.
8337 * lib/subpipe.c: Likewise.
8338 * lib/timevar.c: Likewise.
8339 * lib/vbitset.c: Likewise.
8340 * lib/bitset.c: Include "bitset.h" first, to test interface.
8341 * lib/bitset_stats.c: Include "bitset_stats.h" first.
8342 * lib/bitsetv-print.c: Include "bitsetv-print.h" first.
8343 * lib/bitsetv.c: Include "bitsetv.h" first.
8344 * lib/get-errno.c: Include "get-errno.h" first.
8345 * m4/.cvsignore: Add config-h.m4.
8346 * tests/actions.at (Default %printer and %destructor for ...):
8347 Adjust expected line numbers in output to reflect removal of #if
8348 HAVE_CONFIG_H lines.
8349 * tests/glr-regression.at (Missed %merge type warnings when ...):
8351 * tests/regression.at (Braced code in declaration in rules section):
8353 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
8354 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
8355 Include <config.h> unconditionally.
8357 * bootstrap: Sync from coreutils, as follows:
8359 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8361 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
8362 variable was sometimes used without being initialized. This
8363 messed up the installation of the INSTALL file in some cases.
8365 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8367 * bootstrap (usage, main program, symlink_to_gnulib): Add option
8368 --copy. Inspired by a suggestion from Bruno Haible.
8370 2006-10-03 Jim Meyering <jim@meyering.net>
8372 * bootstrap: Undo last change to this file, since now gnulib-tool
8373 sticks with the automake default in generating dependencies.
8375 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8377 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
8378 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
8380 * doc/bison.1: Add copyright notice.
8382 * data/glr.c: Don't include <stdarg.h>; not used.

8385 DOT format, not VCG format.
8386 * doc/bison.1: Likewise.
8387 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
8388 * THANKS: Add Satya Kiran Popuri, who proposed the initial version

8399 * src/print_graph.h: Likewise.
8400 * src/getargs.c (usage): Make usage description more generic.
8401 * src/print_graph.c: Include graphviz.h rather than vcg.h.
8402 (static_graph, fgraph): Remove. All uses changed to pass
8403 arguments instead of sharing a static var.
8404 (print_core, print_actions, print_state, print_graph):
8405 Output graphviz format rather than VCG format.
8406 * tests/.cvsignore: Remove *.vcg; add *.dot.
8407 * tests/output.at: Expect *.dot files, not *.vcg files.
8409 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
8410 accommodates the 2006-10-08 change.
8412 2006-10-11 Bob Rossi <bob@brasko.net>
8414 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
8415 (b4_yyssa, b4_yyerror_range): New macros.
8416 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
8417 (yypvarsinit): Remove init of removed fields.
8418 (yypushparse): Remove use of removed fields; use new macros instead.
8420 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
8422 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
8423 in a push parser. Reindent slightly to match yacc.c better.
8425 2006-10-11 Bob Rossi <bob@brasko.net>
8427 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
8429 (yypvarsinit, yypushparse): Remove init of removed fields.

8432 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
8434 * THANKS: Add Paolo Bonzini and Bob Rossi.
8436 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
8438 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
8439 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
8440 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
8441 b4_define_user_cde and uses): Remove.
8442 (b4_comment, b4_prefix, b4_sync_start): New.
8443 * data/bison.m4: New file, with most of the content removed from c.m4.
8444 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
8445 * src/output.c (output_skeleton): Pass bison.m4.
8446 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
8449 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
8451 Fix test failure reported by Tom Lane in
8452 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
8453 and try to make such failures easier to catch in the future.
8454 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
8455 that's now the caller's responsibility.
8456 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
8457 Set yychar = YYEOF if it's negative.
8458 * tests/actions.at (yylex): Abort if asked to read past EOF.
8459 * tests/conflicts.at (yylex): Likewise.

8466 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
8468 Fix problems with translating English-language diagnostics.
8469 * bootstrap: Fix bug introduced in recent bootstrap changes, with
8470 respect to bison-runtime pot generation. The YY_ stuff
8471 wasn't being captured.
8472 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
8473 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
8474 * runtime-po/POTFILES.in: Add data/push.c.
8476 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
8478 Merge bootstrap changes from coreutils.
8480 2006-09-28 Jim Meyering <jim@meyering.net>
8482 Automatically generated dependencies are important even
8483 when all of the sources in a directory come from gnulib.
8484 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
8485 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
8487 2006-09-23 Jim Meyering <jim@meyering.net>
8489 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
8491 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8493 * bootstrap: Add support for --force.
8494 (usage): New function. Describe usage less tersely.
8495 (CVS_only_file): New var.
8497 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>

8506 (YYPUSH_MORE): Add #define.
8507 (yypushparse): Modify return value.
8509 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8511 * stamp-h.in: Remove; no longer needed.
8512 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
8513 Remove config.h, config.hin, intl (no longer created).
8514 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
8517 Sync bootstrap from coreutils, as follows:
8519 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
8521 * bootstrap (symlink_to_gnulib): New function.
8522 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
8523 to copies-of-gnulib.
8524 (cp_mark_as_generated, slurp, gnulib_files):
8525 Avoid making a copy if it's the same as the old version.
8526 (gnulib_files): Add support for this variable (used by Bison).
8528 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
8530 * src/getargs.c (usage): Rework to use conventions similar to
8531 coreutils, to make translation a bit easier and the code a bit
8532 smaller. Problem reported by Tim Van Holder.
8534 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
8536 Use some of gnulib's new modules, taken from coreutils.
8538 * bootstrap: Sync from coreutils, except add support for gnulib_files.
8539 * bootstrap.conf: New file.
8540 (gnulib_modules): Add configmake, inttypes, unistd.
8541 (XGETTEXT_OPTIONS): Add complain, complain_at,
8542 fatal, fatal_at, warn, warn_at, unexpected_end.
8543 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
8544 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
8546 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
8548 (GNULIB_AUTOCONF_SNIPPET): Remove.
8549 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
8551 * lib/.cvsignore: Add inttypes_.h.
8552 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
8553 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
8554 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
8555 no-longer-necessary initializations.
8556 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
8557 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
8558 use the unistd module.
8559 * src/system.h: Likewise.
8560 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
8561 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
8562 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
8563 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
8564 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
8565 * src/system.h: Include inttypes.h unconditionally, now that we
8566 use the inttypes module. Don't bother to include stdint.h, since
8567 inttypes.h now does that for us.
8568 (LOCALEDIR): Remove, now that we use the configmake module.
8569 * src/getargs.c: Include configmake.h.
8570 * src/main.c: Likewise.
8571 * src/output.c: Likewise.
8572 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
8573 not from $abs_top_builddir, since config.h moved.
8576 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
8577 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
8579 * src/parse-gram.y (symbol_declaration): Don't put statements
8580 before declarations; it's not portable to C89.
8581 * src/scan-code.l (handle_action_at): Likewise.
8583 * src/scan-code.l: Always initialize braces_level; the old code
8584 left it uninitialized and therefore had undefined behavior.
8586 Don't attempt to redefine 'assert', since it runs afoul of
8587 systems where standard headers (mistakenly) include <assert.h>.
8588 Instead, define and use our own alternative, called 'aver'.
8589 * src/reader.c: Don't include assert.h, since we no longer
8591 * src/scan-code.l: Likewise.
8592 * src/system.h (assert): Remove, replacing with....
8593 (aver): New function, taking a bool arg. All uses changed.
8594 * src/tables.c (pack_vector): Ensure that aver arg is bool,
8595 not merely an integer.
8597 2006-09-15 Bob Rossi <bob@brasko.net>
8599 Add support for push parsing. Based on the original work of
8600 Odd Arild Olsen <oao@fibula.no>.
8601 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
8602 * data/c.m4 (YYPUSH): New.
8603 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
8604 * data/push.c: New file.
8605 * src/getargs.c (push_parser): New var.
8606 * src/getargs.h (push_parser): New declaration.
8607 * src/output.c (prepare): Add macro insertion of `push_flag'.
8608 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
8609 (prologue_declaration): Parse %push-parser.
8610 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
8611 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
8612 list of removed lines from the traces observed.
8613 (AT_CHECK_CALC_LALR): Added push parser tests.
8615 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
8617 * NEWS: Version 2.3a.
8618 * configure.ac (AC_INIT): Likewise.
8620 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
8621 "#define YYSTYPE int" that caused "make maintainer-check" to fail
8622 due to header ordering dependencies. I don't know why the #define
8625 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
8626 runtime cost when YYDEBUG is not defined, and so that some tests
8627 that used to fail now work. Problem and initial suggestion by
8629 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
8630 * data/glr.cc (b4_parser_class_name):
8631 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
8632 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
8633 (yydebug_) [YYDEBUG]: New member.
8634 (yycdebug_): Now defined only if YYDEBUG.
8635 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
8636 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
8637 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
8639 (debug_stream, set_debug_stream, debug_level, set_debug_level):
8640 Define only if YYDEBUG.
8641 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
8643 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
8644 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
8645 AT_CHECK_CALC_GLR_CC that are working now.
8647 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
8649 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
8650 We don't need them in glr.cc, and glr.c defines them.
8651 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
8652 assumes that defining it to anything is the same as defining
8653 it to 1. Problem reported by Paolo Bonzini.
8655 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
8657 * data/c.m4 (b4_null, b4_case): Define.
8658 * src/output.c (prepare_symbols): Use b4_null.
8659 (user_actions_output): Use b4_case.
8661 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
8663 * data/glr.c (b4_shared_declarations): Put start-header first,
8664 before any #includes that we generate, so that feature-test
8665 macros work. Problem reported by Michael Deutschmann in
8666 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
8667 * data/lalr1.cc: Likewise.
8668 * doc/bison.texinfo (Prologue): Document that feature-test macros
8669 should be defined before any Bison declarations.
8670 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
8671 that depend on location.hh after, not before, Bison decls, since
8672 we now include location.hh after the first user prologue.
8674 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
8675 Sander Brandenburg in
8676 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
8677 Also, fix minor white space and comment issues.
8678 (Prologue): Mention that it's better to define feature-test macros
8679 before Bison declarations. Problem reported by Michael Deutschmann.
8681 * README-cvs: Fix typo: "&" should be "&&". Problem reported
8683 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
8684 This adjusts to recent gnulib changes.
8686 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
8688 Finish implementation of per-type %destructor/%printer. Discussed
8690 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
8692 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
8693 * NEWS (2.3+): Add a description of this feature to the default
8694 %destructor/%printer description.
8695 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
8696 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
8697 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
8698 list node contains a semantic type.
8699 * src/symtab.c, src/symtab.h: Extend with a table that associates
8700 semantic types with their %destructor's and %printer's.
8701 (semantic_type_from_uniqstr, semantic_type_get,
8702 semantic_type_destructor_set, semantic_type_printer_set): New functions
8703 composing the public interface of that table.
8704 (symbol_destructor_get, symbol_destructor_location_get,
8705 symbol_printer_get, symbol_printer_location_get): If there's no
8706 per-symbol %destructor/%printer, look up the per-type before trying
8708 * tests/actions.at (Per-type %printer and %destructor): New test case.
8709 * tests/input.at (Default %printer and %destructor redeclared):
8710 Extend to check that multiple occurrences of %symbol-default in a
8711 single %destructor/%printer declaration is an error.
8712 (Per-type %printer and %destructor redeclared, Unused values with
8713 per-type %destructor): New test cases.
8715 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
8717 Require default %destructor/%printer to be declared using
8718 %symbol-default instead of an empty symbol list, and start working on
8719 new per-type %destructor/%printer. Discussed at
8720 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
8721 * NEWS (2.3+): Add %symbol-default to example.
8722 * bison.texinfo (Freeing Discarded Symbols): Likewise.
8723 (Table of Symbols): Add entry for %symbol-default.
8724 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
8725 (generic_symlist, generic_symlist_item): New nonterminals for creating
8726 a list in which each item is a symbol, semantic type, or
8728 (grammar_declaration): Use generic_symlist in %destructor and %printer
8729 declarations instead of symbols.1 or an empty list.
8730 (symbol_declaration, precedence_declaration, symbols.1): Update actions
8731 for changes to symbol_list.
8732 * src/reader.c: Update for changes to symbol_list.
8733 * src/scan-code.l: Likewise.
8734 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
8735 * src/symlist.c, src/symlist.h: Extend such that a list node may
8736 represent a semantic type or a %symbol-default in addition to just an
8737 ordinary symbol. Add switched functions for setting %destructor's and
8739 * tests/actions.at, tests/input.at: Add %symbol-default to all default
8740 %destructor/%printer declarations.
8742 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
8744 Whether the default %destructor/%printer applies to a particular symbol
8745 isn't a question of whether the user *declares* that symbol (in %token,
8746 for example). It's a question of whether the user by any means
8747 *defines* the symbol at all (by simply using a char token, for
8748 example). $end is defined by Bison whereas any other token with token
8749 number 0 is defined by the user. The error token is always defined by
8750 Bison regardless of whether the user declares it with %token, but we
8751 may one day let the user define error as a nonterminal instead.
8752 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
8753 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
8754 the meaning of "user-defined".
8755 * tests/actions.at (Default %printer and %destructor for user-declared
8756 end token): Rename to...
8757 (Default %printer and %destructor for user-defined end token): ...
8760 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
8761 computation of whether to apply the default, don't maintain a list of
8762 every Bison-defined symbol. Instead, just check for a first character
8763 of '$', which a user symbol cannot have, and check for the error token.
8765 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
8767 Don't apply the default %destructor or %printer to the error token,
8768 $undefined, or $accept. This change fits the general rule that the
8769 default %destructor and %printer are only for user-declared symbols,
8770 and it solves several difficulties that are described in the new test
8772 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
8773 * tests/actions.at (Default %printer and %destructor are not for error
8774 or $undefined, Default %printer and %destructor are not for $accept):
8777 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
8779 Allow %start after the first rule.
8780 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
8781 when parsing the first rule.
8782 (check_and_convert_grammar): Search for it here after all grammar
8783 declarations have been parsed. Skip midrules, which have dummy LHS
8785 * src/symtab.c (symbol_is_dummy): New function.
8786 * src/symtab.h (symbol_is_dummy): Declare it.
8787 * tests/input.at (%start after first rule): New test.
8789 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
8791 Redo some of the previous commit: add back the ability to use
8792 non-aliased/undeclared string literals since it might be useful to
8793 those declaring %token-table.
8794 * src/reader.c (check_and_convert_grammar): Undo changes in previous
8795 commit: don't worry about complaints from symbols_pack.
8796 * src/symtab.c (symbol_new, symbol_class_set,
8797 symbol_check_alias_consistency): Undo changes in previous commit: count
8798 each string literal as a new symbol and token, assign it a symbol
8799 number, and don't complain about non-aliased string literals.
8800 (symbols_pack): Since symbol_make_alias still does not decrement symbol
8801 and token counts but does still set aliased tokens to the same number,
8802 symbol_pack_processor now leaves empty slots in the symbols array.
8804 * tests/regression.at (Undeclared string literal): Remove test case
8805 added in previous commit since non-aliased string literals are allowed
8807 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
8808 remove unnecessary string literal declarations.
8809 * tests/sets.at (Firsts): Likewise.
8811 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
8813 Don't allow an undeclared string literal, but allow a string literal to
8814 be used before its declaration.
8815 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
8816 symbols_pack complained.
8817 * src/symtab.c (symbol_new): Don't count a string literal as a new
8819 (symbol_class_set): Don't count a string literal as a new token, and
8820 don't assign it a symbol number since symbol_make_alias does that.
8821 (symbol_make_alias): It's not necessary to decrement the symbol and
8822 token counts anymore. Don't assume that an alias declaration occurs
8823 before any uses of the identifier or string, and thus don't assert that
8824 one of them has the highest symbol number so far.
8825 (symbol_check_alias_consistency): Complain if there's a string literal
8826 that wasn't declared as an alias.
8827 (symbols_pack): Bail if symbol_check_alias_consistency failed since
8828 symbol_pack asserts that every token has been assigned a symbol number
8829 although undeclared string literals have not.
8830 * tests/regression.at (String alias declared after use, Undeclared
8831 string literal): New test cases.
8832 (Characters Escapes, Web2c Actions): Declare string literals as
8834 * tests/sets.at (Firsts): Likewise.
8836 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
8838 In the grammar scanner, STRING_FINISH unclosed constructs and return
8839 them to the parser in order to improve error messages.
8840 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
8841 SC_BRACED_CODE, SC_PROLOGUE): Implement.
8842 * tests/input.at (Unclosed constructs): New test case.
8843 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
8846 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
8849 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
8851 Handle string aliases for character tokens correctly.
8852 * src/symtab.c (symbol_user_token_number_set): If the token has an
8853 alias, check and set its alias's user token number instead of its own,
8854 which is set to indicate the alias. Previously, every occurrence of
8855 the character token in the grammar overwrote that alias indicator with
8857 * tests/input.at (String aliases for character tokens): New test.
8859 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
8861 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
8863 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
8865 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
8866 to prevent failures when building on older platforms.
8867 Check for autopoint failure.
8868 Set XGETTEXT_OPTIONS to values that check for C format strings,
8869 so that translators are warned about them (this also helps
8870 prevent core dumps).
8872 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
8873 function, since it simplifies our code a bit.
8875 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
8876 rather than -W, so we don't get bogus warnings about sign comparisons.
8877 Add -Wpointer-arith, since that warning is useful (it reports code
8878 that does not conform to C89 and that some compilers reject).
8879 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
8880 since it's no longer needed.
8882 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
8884 Clean up scanners a bit.
8885 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
8886 definitions so gcc won't warn when obstack_for_string is unused.
8887 * src/scan-code.l: config.h and system.h are already #include'd by
8888 scan-code-c.c, so get rid of them here.
8889 * src/scan-gram.l: Likewise.
8890 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
8891 definitions rather than duplicating the rest of it.
8892 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
8894 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
8896 Suppress signed/unsigned comparison warnings for yycheck.
8897 * data/c.m4 (b4_safest_int_type): New macro.
8898 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
8899 a signed int type, cast it to b4_safest_int_type first.
8900 * data/yacc.c: Likewise.
8901 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
8904 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
8906 * doc/bison.texinfo: Fix some typos.
8908 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
8910 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
8911 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
8913 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
8914 the latest gnulib does this a different way.
8915 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
8916 translation was patched, so stop omitting it.
8918 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
8920 Enable declaration of default %printer/%destructor. Make the parser
8921 use these for all user-declared grammar symbols for which the user does
8922 not declare a specific %printer/%destructor. Thus, the parser uses it
8923 for token 0 if the user declares it but not if Bison generates it as
8924 $end. Discussed starting at
8925 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
8926 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
8928 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
8929 * NEWS (2.3+): Mention.
8930 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
8931 declare a %destructor for a mid-rule's semantic value. It's just
8932 impossible to declare one specific to it.
8933 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
8934 code. Describe default %destructor form.
8935 * src/parse-gram.y (grammar_declaration): Parse default
8936 %printer/%destructor declarations.
8937 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
8938 and symbol_destructor_location_get rather than accessing the destructor
8939 and destructor_location members of struct symbol.
8940 (symbol_printers_output): Likewise but for %printer's.
8941 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
8943 * src/symtab.c (default_destructor, default_destructor_location,
8944 default_printer, default_printer_location): New static global
8945 variables to record the default %destructor and %printer.
8946 (symbol_destructor_get, symbol_destructor_location_get,
8947 symbol_printer_get, symbol_printer_location_get): New functions to
8948 compute the appropriate %destructor and %printer for a symbol.
8949 (default_destructor_set, default_printer_set): New functions to set the
8950 default %destructor and %printer.
8951 * src/symtab.h: Prototype all those new functions.
8952 * tests/actions.at (Default %printer and %destructor): New test to
8953 check that the right %printer and %destructor are called, that they're
8954 not called for $end, and that $$ and @$ work correctly.
8955 (Default %printer and %destructor for user-declared end token): New
8956 test to check that the default %printer and %destructor are called for
8957 a user-declared end token.
8958 * tests/input.at (Default %printer and %destructor redeclared, Unused
8959 values with default %destructor): New tests to check related grammar
8960 warnings and errors.
8962 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
8964 Clean up handling of %destructor for the end token (token 0).
8965 Discussed starting at
8966 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
8968 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
8970 Make the skeletons consistent in how they pop the end token and invoke
8972 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
8973 state, which has token number 0, since this would invoke the
8974 %destructor for the end token.
8975 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
8976 until after shifting the end token, or else it won't be popped.
8977 * data/yacc.c (yyparse): Likewise.
8979 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
8980 it's the end token. Upon termination, destroy an unshifted lookahead
8981 even when it's the end token.
8982 * data/lalr1.cc (yy::parser::parse): Likewise.
8983 * data/yacc.c (yyparse): Likewise.
8985 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
8986 value warnings for the end token when the user gives the end token a
8989 * tests/actions.at (Printers and Destructors): Test all the above.
8991 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
8993 Update to latest gnulib and gettext versions.
8994 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
8996 (gnulib_files): Add m4/warning.m4. Don't worry about files
8997 overwritten by autopoint.
8998 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
8999 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
9001 Don't use autoreconf; instead, invoke autopoint etc. by hand,
9002 so that we can remove the intl files at a better time.
9003 (intl_files_to_remove): Remove aclocal.m4, since it gets
9004 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
9005 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
9006 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
9007 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
9008 Remove datarootdir hack; no longer needed.
9009 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
9010 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
9011 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
9013 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
9014 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
9016 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
9018 * bootstrap: Adjust to today's change to gnulib-tool by invoking
9019 it with --assume-autoconf='latest-stable'.
9021 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
9023 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
9024 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
9026 * src/muscle_tab.h (muscle_grow): Replace the header comments with
9027 those from muscle_tab.c since the old ones are misleading.
9029 2006-07-13 Akim Demaille <akim@epita.fr>
9031 Support %define "KEY" {VALUE}.
9032 * src/scan-code.h, src/scan-code.l (translate_action)
9033 (translate_rule_action, translate_symbol_action, translate_code):
9034 Return char *, not const char *.
9035 * src/parse-gram.y (declaration): Rename as...
9036 (prologue_declaration): this.
9037 (string_content): Remove this nonterminal, use STRING.
9038 (braceless, content, content.opt): New nonterminal.
9040 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
9042 * src/scan-gram.l (getargs.h): Don't include it.
9044 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
9046 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
9047 rather than a for-loop that declares a local bool variable. This
9048 should work around a compatibility problem with a Cray x1e C++
9049 compiler reported by Hung Nguyen in
9050 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
9051 The for-loop was introduced in the 2004-11-17 change but I don't
9052 know why it was needed.
9054 2006-07-12 Akim Demaille <akim@epita.fr>
9056 * data/c.m4: Comment changes.
9058 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
9060 * src/complain.c (error_message, ERROR_MESSAGE): New.
9062 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
9063 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
9065 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9067 * NEWS: Instead of %union, you can define and use your own union type
9068 YYSTYPE if your grammar contains at least one <type> tag.
9069 Your YYSTYPE need not be a macro; it can be a typedef.
9070 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
9071 (Union Decl, Decl Summary): Document this.
9072 * data/glr.c (YYSTYPE): Implement this.
9073 * data/glr.cc (YYSTYPE): Likewise.
9074 * data/lalr1.cc (YYSTYPE): Likewise.
9075 * data/yacc.c (YYSTYPE): Likewise.
9076 * src/output.c (prepare): Output tag_seen_flag.
9077 * src/parse-gram.y (declaration, grammar_declaration):
9078 Use 'union_seen' rather than 'typed' to determine whether
9079 %union has been seen, since grammars can now be typed without
9081 (symbol_declaration, type.opt, symbol_def):
9082 Keep track of whether a tag has been seen.
9083 * src/reader.c (union_seen, tag_seen): New vars.
9085 * src/reader.h (union_seen, tag_seen, typed): Likewise.
9086 * src/scan-code.l (untyped_var_seen): New variable.
9087 (handle_action_dollar): Adjust to above changes.
9088 (handle_action_dollar, handle_action_at):
9089 Improve overflow checking for outlandish numbers.
9090 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
9091 avoid new diagnostics generated by above changes.
9092 * tests/regression.at (YYSTYPE typedef): Add test to check
9093 for type tags without %union.
9095 * src/symlist.c (symbol_list_length): Return int, not unsigned
9096 int, since callers expect int. This may need to get revisited
9097 once we have proper integer overflow checking.
9099 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
9100 object is now static.
9102 * src/getargs.c (flags_argmatch): Return void, not int,
9103 to pacify ./configure --enable-gcc-warnings.
9105 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
9106 since last_string is already defined to FLEX_PREFIX (last_string).
9108 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9110 Implement --warnings/-W.
9111 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
9113 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
9115 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
9116 (warnings_args, warnings_types): New.
9117 (getargs, short_options, long_options): Accept -W/--warnings.
9118 Sort the options by alphabetical order, upper case letter right
9119 before its lower case.
9121 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
9123 Change %merge result type clash warnings to errors. Discussed at
9124 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
9125 * src/reader.c (record_merge_function_type): Use complain_at.
9126 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9127 declared later): Update test case results.
9129 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
9131 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
9132 to be in alphabetical order.
9133 (trace_args): Spelling fixes.
9135 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
9137 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
9138 so they don't collide with user-defined macros.
9139 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
9140 this was never guaranteed, and now that we're using gnulib stdint,
9141 which defines int_fast16_t to long int, the problem is exposed.
9143 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
9145 * data/c.m4 (b4_basename): Simplify a bit, since we don't
9146 need the full POSIX semantics (and weren't implementing them
9149 Adjust to Autoconf 2.60 and today's gnulib.
9150 * bootstrap (gnulib_modules): Add stdint.
9151 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
9152 no longer copies it.
9153 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
9154 since stdint needs the former and wcwidth (which is now required
9155 by mbswidth) needs the latter.
9156 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
9157 work around a compatibility glitch between gettext 0.14.6 and
9159 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
9160 Do not check for uintptr_t, since new stdint module does the right
9162 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
9163 Add stdint.h, stdint_.h, wcwidth.h.
9164 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
9165 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
9166 stdint.m4, wchar_t.m4, wcwidth.m4.
9167 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
9168 usual order for ../lib/*.h files.
9169 (file_name_split): Use last_component, not base_name, to adjust
9171 * src/parse-gram.h: Include <strverscmp.h> in the usual order
9172 for ../lib/*.h files.
9173 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
9174 Define unconditionally, since we now assume the stdint module.
9175 * src/scan-skel.l: Include <dirname.h>.
9176 (BASE_QPUTS): Use last_component, not base_name.
9177 * src/system.h: Include <unlocked-io.h> in the usual order
9178 for ../lib/*.h files. Include <stdint.h> unconditionally,
9179 since we now use the stdint module.
9180 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
9181 HAVE_UINTPTR_T, since we now use the stdint module.
9182 (base_name): Remove decl, since files now include <dirname.h>
9185 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9187 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
9189 * data/yacc.c, data/glr.c, data/location.cc: Use them.
9190 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
9192 * tests/calc.at: Adjust.
9194 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
9196 * data/c.m4 (b4_basename): New.
9197 (b4_syncline): Also output the location of its invocation (from
9199 (b4_user_action, b4_define_user_action, b4_user_actions)
9200 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
9201 (b4_user_stype): New.
9202 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
9204 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9206 In the grammar file, the first column is 1 not 0 on the first line as
9207 on every other line.
9208 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
9209 * tests/input.at (Torturing the Scanner): Update output.
9211 * src/scan-gram.l (scanner_cursor): Declare it static.
9213 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
9215 In warnings, say "previous declaration" rather than "first
9217 * src/symtab.c (redeclaration): Do that here.
9218 * src/reader.c (record_merge_function_type): In the case of a result
9219 type clash, report the previous declaration rather than the very first
9220 one in the grammar file.
9221 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9222 declared later): Add a third declaration to check this behavior.
9223 * tests/input.at (Incompatible Aliases): Update output.
9225 2006-06-27 Akim Demaille <akim@epita.fr>
9227 * doc/Doxyfile.in: New.
9228 * doc/Makefile.am: Use it.
9229 * src/lalr.h, src/symtab.h: Initial doxygenation.
9231 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9233 Don't miss %merge result type warnings just because the LHS types are
9234 declared after the %merge. This continues the effort of the previous
9236 * src/reader.c (get_merge_function): Don't set the merger type yet.
9237 (record_merge_function_type): New function for setting the merger type
9238 and checking for clashes.
9239 (grammar_current_rule_merge_set): Set the location of the %merge for
9241 (packgram): Invoke record_merge_function_type for each rule now that
9242 all symbol type declarations have been parsed.
9243 * src/reader.h (merger_list.type_declaration_location): New member
9244 storing the location of the first %merge from which the type for this
9245 merging function was derived.
9246 * src/symlist.h (symbol_list.merger_declaration_location): New member
9247 storing the location of a rule's %merge, if any.
9248 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
9249 declared later): New test to catch the error fixed by the above patch.
9251 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9253 Get action warnings (grammar_rule_check) right even when symbol
9254 declarations appear after the rules. Discussed at
9255 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
9257 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
9258 Don't mistake the type of $$ in a midrule to be that of its parent
9260 * src/reader.c (grammar_current_rule_end): Don't invoke
9261 grammar_rule_check yet since not all symbol declarations may have been
9263 (grammar_midrule_action): Likewise.
9264 Don't record whether the midrule's $$ has been used yet since actions
9265 haven't been translated yet.
9266 Record the midrule's parent rule and its RHS index within the parent
9268 (grammar_current_rule_action_append): Don't translate the action yet
9269 since not all symbol declarations may have been parsed yet and, thus,
9270 warnings about types for $$, $n, @$, and @n can't be reported yet.
9271 (packgram): Translate the action and invoke grammar_rule_check now that
9272 all symbol declarations have been parsed.
9273 * src/scan-code.l (handle_action_dollar): Now that this is invoked
9274 after parsing the entire grammar file, the symbol list here in the case
9275 of a midrule is actually the midrule's empty RHS, so reference its
9276 parent rule's RHS where necessary.
9277 On the other hand, now that you can already know it's a midrule, you
9278 aren't forced to think $$ has the same type as its parent rule's $$.
9279 (handle_action_at): In the case of a midrule, reference the parent rule
9281 * src/symlist.c (symbol_list_new): Initialize new midrule-related
9283 (symbol_list_length): Now that this is invoked after all rules have
9284 been parsed, a NULL symbol (rather than a NULL symbol list node)
9285 terminates a rule. symbol_list_print already does this correctly.
9286 * src/symlist.h (symbol_list.midrule_parent_rule,
9287 symbol_list.midrule_parent_rhs_index): New members so that midrules can
9288 remember their relationships with their parents.
9289 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
9290 fixed by the above patch.
9291 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
9293 (Unused values): ... this old test case and...
9294 (Unused values before symbol declarations): ... this new test case.
9295 This one is the same as `Unused values' except that all symbol
9296 declarations appear after the rules in order to catch the rest of the
9297 errors fixed by the above patch.
9299 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
9302 * src/reader.c (current_rule): Declare it static since it's no longer
9303 used outside this file.
9304 (grammar_current_rule_action_append): Remove redundant arguments from
9305 translate_rule_action invocation.
9306 * src/reader.h (current_rule): Remove this unused extern.
9307 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
9308 * src/scan-code.l (translate_rule_action): Likewise.
9310 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
9312 Clean up yesterday's patch.
9313 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
9315 * src/reader.c (grammar_current_rule_action_append): ... here for
9316 consistency with grammar_current_rule_symbol_append.
9317 * tests/regression.at (Braced code in declaration in rules section):
9318 Make yyerror and yylex static as usual.
9320 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
9322 Fix bug that mistakes braced code in a declaration in the rules section
9323 to be a rule action. Mentioned at
9324 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
9325 * src/scan-gram.l: Move midrule action detection from the start of the
9326 scanning of any braced code to...
9327 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
9328 action. For readability, use $2 and @2 rather than the equivalent
9330 * tests/regression.at (Braced code in declaration in rules section):
9331 New test to catch the error fixed by the above patch.
9333 Work on code readability some.
9334 * src/scan-code.l (current_rule): Get rid of this misleading and
9335 redundant declaration: it's actually extern'ed in reader.h.
9336 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
9337 translate_action): Add a rule argument and use it instead of the global
9339 (translate_rule_action): This already receives current_rule through an
9340 argument, so pass it on to translate_action instead of assigning
9341 current_rule to current_rule.
9342 (translate_symbol_action, translate_code): Pass rule = NULL to
9345 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
9347 Rename %before-definitions to %start-header and %after-definitions to
9348 %end-header. Don't use these declarations to separate pre-prologue
9349 blocks from post-prologue blocks. Add new order-independent
9350 declarations %before-header and %after-header as alternatives to the
9351 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
9352 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
9353 * NEWS (2.3+): Update for these changes.
9354 * data/glr.c (b4_before_definitions): Update to...
9355 (b4_start_header): ... this.
9356 (b4_after_definitions): Update to...
9357 (b4_end_header): ... this.
9358 * data/glr.cc: Likewise.
9359 * data/lalr1.cc: Likewise.
9360 * data/yacc.c: Likewise.
9361 * doc/bison.texinfo (The prologue): Update names, and replace remaining
9362 prologue blocks with %*-header declarations.
9363 (Calc++ Parser): Likewise.
9364 (Decl Summary): Update names.
9365 (Table of Symbols): Update description.
9366 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
9367 (PERCENT_END_HEADER): ... this.
9368 (PERCENT_BEFORE_DEFINITIONS): Update to...
9369 (PERCENT_START_HEADER): ... this.
9370 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
9371 (declaration): Update token names and m4 macro names.
9372 When parsing %end-header and %start-header, invoke translate_code
9373 before muscle_code_grow, and no longer set global booleans to remember
9374 whether these declarations have been seen.
9375 Parse new %after-header and %before-header.
9376 * src/reader.c (before_definitions, after_definitions): Remove.
9377 (prologue_augment): Accept a new bool argument to specify whether to
9378 augment the pre-prologue or post-prologue.
9379 * src/reader.h (before_definitions, after_definitions): Remove these
9381 (prologue_augment): Add new bool argument.
9382 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
9383 (PERCENT_END_HEADER): ... this.
9384 (PERCENT_BEFORE_DEFINITIONS): Update to...
9385 (PERCENT_START_HEADER): ... this.
9386 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
9387 * tests/actions.at (Printers and Destructors): Update names.
9389 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
9391 Add comparison operators for C++ location classes. Discussed at
9392 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
9393 * data/c++.m4 (b4_define_location_comparison): New boolean %define
9394 declaration indicating whether filename_type has an operator==. If
9395 filename_type is `std::string', it defaults to `1', `0' otherwise.
9396 * data/location.cc: Iff b4_define_location_comparison is `1', add
9397 operator== and operator!= for class position and for class location.
9400 * src/scan-action.l: Remove unused file.
9401 * src/symtab.c (symbol_printer_set): Use printer_location not
9402 destructor_location.

9405 * tests/input.at (Incompatible Aliases): Update output with correct
9408 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
9410 Don't put the pre-prologue in the header file. For the yacc.c code
9411 file and the glr.c header and code files, move the pre-prologue before
9412 the token definitions. Add new %before-definitions and
9413 %after-definitions to declare code that will go in both the header file
9414 and code file. Discussed at
9415 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
9416 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
9418 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
9419 * NEWS (2.3+): Describe these changes.
9420 * data/glr.c (b4_pre_prologue): Move from within to before...
9421 (b4_shared_declarations): ... this.
9422 Add new b4_before_definitions before b4_token_enums.
9423 Add new b4_after_definitions at the end.
9424 * data/glr.cc (b4_pre_prologue): Replace with...
9425 (b4_before_definitions): ... this in the header file.
9426 (b4_after_definitions): New near the end of the header file.
9427 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
9428 code file right before including the header file.
9429 (b4_before_definitions): New in the previous position of
9430 b4_pre_prologue in the header file.
9431 (b4_after_definitions): New near the end of the header file.
9432 * data/yacc.c: Clean up some m4 quoting especially in the header file.
9433 (b4_token_enums_defines): In the code file, move to right before
9434 YYSTYPE for consistency with the header file.
9435 (b4_before_definitions): New right before b4_token_enums_defines in
9436 both the header and code file.
9437 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
9438 header and code file.
9439 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
9440 of prologues for %union dependencies.
9441 (Decl Summary): In %defines description, mention the effect of
9442 %before-definitions and %after-definitions on the header file.
9443 (Calc++ Parser): Forward declare driver in a %before-definitions rather
9444 than in the pre-prologue so that make check succeeds.
9445 (Table of Symbols): Add entries for %before-definitions and
9447 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
9448 %before-definitions.
9449 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
9450 (declaration): Parse those declarations and append to
9451 b4_before_definitions and b4_after_definitions, respectively.
9452 * src/reader.c (before_definitions, after_definitions): New bools to
9453 track whether those declarations have been seen.
9454 (prologue_augment): Add to the post-prologue if %union,
9455 %before-definitions, or %after-definitions has been seen.
9456 * src/reader.h (before_definitions, after_definitions): New extern's.
9457 * src/scan-gram.l: Scan the new declarations.
9458 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
9459 prologue block in a %before-definitions or a %after-definitions based
9460 on whether the %union is declared.
9461 * tests/regression.at (Early token definitions with --yacc, Early token
9462 definitions without --yacc): Move tests for token definitions into the
9463 post-prologue since token names are no longer defined in the
9466 2006-06-20 Akim Demaille <akim@epita.fr>
9468 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
9469 (symbol_get): Use it.
9470 * src/parse-gram.y: Use it.
9472 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
9474 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
9475 build succeeds when configured with --enable-gcc-warnings.
9477 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9479 * src/parse-gram.y (char_name): New function.
9480 (CHAR, STRING, string_content): For %printer, properly escape.
9481 (ID): Prefer fputs to fprintf.
9482 (id): Reindent to be consistent with other rules.
9483 Properly quote char.
9485 The Translation Project changed its way of publishing translations
9486 to maintainers. I haven't received any responses to my request
9487 for supporting the old way, or for documenting the new way. I
9488 have modified 'bootstrap' to use screen scraping
9489 (in this case, HTML scraping). This is unreliable and inelegant,
9490 but I don't see any better way. Yuck.
9491 * bootstrap (TP_URL, WGET_COMMAND): New vars.
9492 (get_translations): New function, which uses HTML scraping to
9493 deduce locations of latest translations.
9494 Use this function to grab both bison and bison-runtime .po files.
9495 Don't bother priming the pump for the runtime-po domain any more,
9496 as it's now translated better than bison is.
9498 2006-06-19 Akim Demaille <akim@epita.fr>
9500 * src/scan-gram.l: No longer "parse" things after `%union' until
9501 `{'. Rather, return a single "%union" token.
9502 No longer make symbols: return strings, and leave the conversion
9503 to symbols to the parser.
9504 (SC_PRE_CODE, token_type): Remove.
9505 * src/parse-gram.y (%union): New field `character'.
9508 (ID, ID_COLON): Now that the scanner no longer makes them
9509 identifiers, adjust all uses to invoke symbol_get.
9510 (id_colon): New, wraps the conversion from string to symbol.
9511 (%union): Accept a possible union_name.
9512 (symbol): Now can be a char.
9513 * data/c.m4 (b4_union_name): Leave a default value.
9514 * data/glr.c, data/yacc.c: Use it.
9516 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
9518 For associating token numbers with token names for "yacc.c", don't use
9519 #define statements unless `--yacc' is specified; always use enum
9520 yytokentype. Most important discussions start at:
9521 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
9522 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
9524 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
9525 * NEWS (2.3+): Mention.
9526 * data/c.m4 (b4_yacc_if): New.
9527 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
9529 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
9530 on token name definitions.
9531 * src/getargs.c (usage): Capitalize `Yacc' in English.
9532 * src/output.c (prepare): Define b4_yacc_flag.
9533 * tests/regression.at (Early token definitions): Test that tokens names
9534 are defined before the pre-prologue not just before the post-prologue.
9535 Remove this test case and copy to...
9536 (Early token definitions with --yacc): ... this to test #define's.
9537 (Early token definitions without --yacc): ... and this to test enums.
9539 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
9541 * NEWS: Reword the post-2.3 change to not be so optimistic about
9542 removing the old "look-ahead" spelling.
9543 Update previous look-ahead/lookahead change reports.
9544 * REFERENCES: look-ahead -> lookahead (since that's
9545 what he actually wrote).
9546 * doc/refcard.tex: look ahead -> lookahead,
9547 look-ahead -> lookahead
9549 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
9551 For consistency, use `lookahead' instead of `look-ahead' or
9552 `look_ahead'. Discussed starting at

9643 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
9645 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
9646 loc argument as it shadows a global.
9647 * src/scan-gram.l: Remove stray comma that prevents boundary_set
9650 * src/.cvsignore: Add scan-code.c.
9652 2006-06-07 Akim Demaille <akim@epita.fr>
9654 * src/scan-gram.l: Move the "add a trailing ; to actions" code
9656 * src/scan-code.l: here.
9657 * tests/input.at (Torturing the Scanner): Fix another location
9660 2006-06-07 Akim Demaille <akim@epita.fr>
9662 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
9664 2006-06-06 Akim Demaille <akim@epita.fr>
9666 Extract the parsing of user actions from the grammar scanner.
9667 As a consequence, the relation between the grammar scanner and
9668 parser is much simpler. We can also split "composite tokens" back
9670 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
9671 * src/scan-gram.l (add_column_width, adjust_location): Move to and
9673 * src/location.h, src/location.c (add_column_width)
9674 (location_compute): these.
9675 Fix the column count: the initial column is 0.
9676 (location_print): Be robust to ending column being 0.
9677 * src/location.h (boundary_set): New.
9678 * src/main.c: Adjust to scanner_free being renamed as
9680 * src/output.c: Include scan-code.h.
9681 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
9683 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
9684 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
9685 which is now, again, a separate token.
9686 Adjust all dependencies.
9687 Whereever actions with $ and @ are used, use translate_code.
9688 (action): Remove this nonterminal which is now useless.
9689 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
9690 (grammar_current_rule_action_append): Use translate_code.
9691 (packgram): Bound check ruleno, itemno, and rule_length.
9692 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
9693 (last_string, last_braced_code_loc, max_left_semantic_context)
9694 (scanner_initialize, scanner_free, scanner_last_string_free)
9695 (gram_out, gram_lineno, YY_DECL_): Move to...
9696 * src/scan-gram.h: this new file.
9697 (YY_DECL): Rename as...
9699 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
9700 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9701 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9702 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9703 Move these declarations, and...
9704 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
9706 * src/flex-scanner.h: this new file.
9707 * src/scan-gram.l (rule_length, rule_length_overflow)
9708 (increment_rule_length): Remove.
9709 (last_braced_code_loc): Rename as...
9710 (gram_last_braced_code_loc): this.
9711 Adjust to the changes of the parser.
9712 Move all the handling of $ and @ into...
9713 * src/scan-code.l: here.
9714 * src/scan-gram.l (handle_dollar, handle_at): Remove.
9715 (handle_action_dollar, handle_action_at): Move to...
9716 * src/scan-code.l: here.
9717 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
9718 scan-code.h, scan-code-c.c, scan-gram.h.
9719 (EXTRA_bison_SOURCES): Add scan-code.l.
9720 (BUILT_SOURCES): Add scan-code.c.
9721 (yacc): Be robust to white spaces.
9723 * tests/conflicts.at, tests/input.at, tests/reduce.at,
9724 * tests/regression.at: Adjust the column numbers.
9725 * tests/regression.at: Adjust the error message.
9727 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
9729 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
9730 Use Akim's wording from
9731 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
9733 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
9735 Between Bison releases, manually append `+' to the previous Bison
9736 release number, and use that as a signal to automatically print the
9737 ChangeLog's CVS Id keyword from --version. Discussed starting at
9738 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
9739 * ChangeLog: Add Id header.
9740 * configure.ac (AC_INIT): Append `+' to `2.3'.
9741 * src/.cvsignore: Add revision.c.
9742 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
9743 (BUILT_SOURCES): Add revision.c.
9744 (revision.c): New target rule. This file defines a new global variable
9745 named revision. It initializes it with either the Id from ChangeLog
9746 or, if VERSION doesn't contain `+', with the empty string.
9747 * src/getargs.c (version): Print the value of revision.
9748 * src/revision.h: Extern revision.
9750 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9752 * NEWS: Version 2.3.
9753 * configure.ac (AC_INIT): Likewise.
9755 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9757 * data/glr.c (YYRECOVERING): Define to be a function-like macro
9758 with no arguments, not as an object-like macro. This is for
9759 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
9760 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
9761 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
9764 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
9766 * src/getargs.c (usage): Back out yesterday's modification of the
9767 --help output so that we don't have to wait for translation before
9770 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9772 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
9773 Problem reported by Akim Demaille.
9775 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
9777 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
9779 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9781 * data/yacc.c (yy_reduce_print): Omit trailing white space in
9782 generated source code. Problem reported by Frans Englich in
9783 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
9785 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
9787 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
9788 shell, not within 'make', so that 'make' by an ordinary builder
9789 (using GNU make) does not worry about configuring gzip. This also
9790 works around a bug reported independently by Keith Thompson and by
9791 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
9792 stderr rather than stdout, messing up the build logs.
9794 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
9796 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
9797 to make sure that YYID will never be unused. This fixes a 'make
9798 maintainer-check' failure caused by the recent changes to the 'Trivial
9799 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
9801 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
9803 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
9805 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
9806 state before an empty RHS is always resolved here. Only the location
9807 of that state is guaranteed to be resolved, and that's enough. This
9808 fixes the remaining bug reported by Derek M. Jones in
9809 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
9810 * tests/glr-regression.at (Uninitialized location when reporting
9811 ambiguity): Test the above case.
9812 Also, the embedded comments in this test case claim it checks the case
9813 of an empty RHS that has inherited the initial location. However, the
9814 corresponding LHS was already resolved, so yyresolveLocations didn't
9815 actually have reason to modify it. Fix this by forcing
9816 nondeterministic operation at the beginning of the parse.
9818 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9820 * data/c.m4 (b4_yy_symbol_print_generate):
9821 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
9822 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
9823 of the bugs reported today by Derek M Jones in
9824 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
9825 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
9826 defined to be a type name without parens or brackets.
9827 (Location Type): Similarly for YYLTYPE.
9828 * tests/regression.at (Trivial grammars): Put in a test for this
9829 bug that will be caught by 'make maintainer-check' (though not,
9830 alas, by 'make check' unless your compiler is picky).
9832 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9834 * NEWS: Version 2.2.
9835 * configure.ac (AC_INIT): Likewise.
9837 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
9839 * data/glr.c (yyreportTree): Make room in yystates for the state
9840 preceding the RHS. This fixes the segmentation fault reported by Derek
9842 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
9843 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
9844 to the user. Reported for yyreportTree by Derek M. Jones later in the
9846 * THANKS: Add Derek M. Jones.
9847 Update my email address.
9848 Fix typo in Steve Murphy's name.
9850 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9852 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
9853 checking against YYLAST that caused the parser to miss a potential
9854 alternative in its diagnostic.
9855 Problem reported by Maria Jose Moron Fernandez in
9856 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
9857 * data/lalr1.cc (yysyntax_error_): Likewise.
9858 * data/yacc.c (yysyntax_error): Likewise.
9859 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
9860 tokens, in case we run into an older C compiler.
9861 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
9862 Use them to check for the off-by-one error fixed above.
9864 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
9865 YYSIZE_T, not size_t.
9866 * tests/regression.at (Trivial grammars): New test, to catch
9867 the error fixed by the above patch.
9869 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9871 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
9873 Reported by Steve Murphy.
9875 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9877 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
9878 * data/glr.cc: b4_location_flag is now b4_locations_flag.
9880 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9882 Implement --trace=m4.
9883 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
9884 * src/output.c (output_skeleton): When set, pass -dV to m4.
9886 Factor the handling of flags in m4.
9887 * src/output.c (prepare): Rename the muscle names debug, defines,
9888 error_verbose to debug_flag, defines_flag, error_verbose_flag.
9889 * data/c.m4: Adjust.
9890 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
9891 Use b4_define_flag_if to define other b4_FLAG_if macros.
9892 (b4_location_if): As a consequence, rename as...
9893 (b4_locations_if): this, for consistency.
9894 Adjust all the skeletons.
9896 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9898 * etc/bench.pm: Shorten bench names.
9900 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
9902 * src/output.h, src/output.c (error_verbose): Move to...
9903 * src/getargs.h, src/getargs.c: here.
9905 Adjust dependencies.
9907 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9909 * data/c.m4 (b4_copyright): Put the special exception for Bison
9910 skeletons here, so we don't have to put it in each skeleton. All
9911 uses changed. Suggested by Akim Demaille. Also, wrap the
9912 copyright notice, in case it is longer than 80 columns. Replace
9913 comma by newline after title.
9915 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9917 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
9918 incompatibility, not a bug. Mention that it wasn't fixed as of
9921 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9923 * examples/extexi: Enforce the precedence of concatenation over
9925 Reported by Tommy Nordgren.
9927 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
9929 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
9930 with the member "token".
9931 Reported by Martin Nylin.
9933 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
9935 * data/glr.c: Switch to Bison 2.2 special-exception language in
9936 the copyright notice. Use more-regular format for titles and
9938 * data/glr.cc: Likewise.
9939 * data/location.cc: Likewise.
9940 * data/yacc.cc: Likewise.
9941 * doc/bison.texinfo (Conditions): Document this.
9942 * NEWS: likewise. Upgrade version to 2.2.
9944 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
9946 * data/glr.cc: Remove dead code.
9948 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9950 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
9951 that variable and the line breaks the bootstrap. Problem reported
9952 by Juan M. Guerrero.
9954 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
9956 * doc/bison.texinfo (Multiple start-symbols): New.
9958 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
9960 * etc/README, etc/bench.pl: New.
9962 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
9964 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
9966 Reported by Mickael Labau.
9967 * tests/input.at (Torturing the Scanner): Test it.
9969 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
9971 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
9972 Problem reported by Bob Rossi.
9974 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
9976 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
9977 and didn't really work.
9978 For the index, use @ifnotinfo, not @iftex.
9979 Minor cleanups of spacing and terminology.
9981 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
9983 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
9984 of AT_NAME_PREFIX when %name-prefix is not used.
9986 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
9988 Apply --prefix to C++ skeletons too: they change the namespace.
9989 The test suite already exercize these cases.
9990 * data/c++.m4 (b4_namespace): New.
9991 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
9992 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
9993 * data/yacc.c, data/glr.c: Remove a useless `[]'.
9994 * doc/bison.texinfo: Document it.
9995 (Option Cross Key): Use @multitable in all formats. It looks
9996 nicer, even in TeX outputs.
9997 (Rules): Use the same code whatever the output type is.
9998 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
9999 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
10000 * tests/calc.at: Use it, instead of hard coding `yy'.
10002 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
10004 * TODO: Remove dead items.
10006 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
10008 * doc/FAQ: Remove, merged into...
10009 * doc/bison.texinfo (FAQ): this.
10010 * doc/Makefile.am (EXTRA_DIST): Adjust.
10012 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
10014 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
10016 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
10017 * doc/bison.texinfo (Calc++ Scanner): Use it.
10019 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
10021 Fix two nits reported by twlevo, plus one more that I discovered.
10023 * src/assoc.h (assoc_to_string): Give a name to the arg, as
10024 this is the usual Bison style.
10025 * src/location.h (location_print): Likewise.
10027 * src/reader.h (token_name): Likewise.
10029 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
10031 Fix some nits reported by twlevo.
10032 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
10033 and "POSIX". Use more-modern syntax for URLs. Mention C++
10034 and ask for Java. Don't hardwire OS version numbers. Add
10036 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
10037 * src/conflicts.c (solved_conflicts_obstack): Now static.
10039 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
10041 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
10042 page. Say "you can use it" not "you may use it" as on the web page;
10043 we're describing capabilities not granting permission.
10045 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
10047 * data/glr.c (yyresolveLocations): Rename local variables to avoid
10048 shadowing warnings. Use usual patter for iterating through RHS.
10049 * tests/glr-regression.at
10050 (Uninitialized location when reporting ambiguity):
10051 Modify yylex so that it uses its argument, rather than trying
10052 to rely on ARGSUSED (which doesn't work for gcc with warnings).
10053 const char -> char const.
10055 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
10056 Don't use tabs inside commands; it messes up 'ps'.
10057 Problem reported by twlevo.
10059 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
10061 * tests/glr-regression.at (Uninitialized location when reporting
10062 ambiguity): New test case.
10063 * data/glr.c (yyresolveLocations): New function, which uses
10065 (yyresolveValue): Invoke yyresolveLocations before reporting an
10067 * doc/bison.texinfo (Default Action for Locations): Note
10068 YYLLOC_DEFAULT's usage for ambiguity locations.
10069 (GLR Semantic Actions): Cross-reference those notes.
10071 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
10073 * tests/glr-regression.at (Leaked semantic values when reporting
10074 ambiguity): Remove unnecessary union and type declarations.
10075 (Leaked lookahead after nondeterministic parse syntax error): New test
10077 * data/glr.c (yyparse): Check for zero stacks remaining before
10078 attempting to shift the lookahead so that you don't lose it.
10080 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10082 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
10083 * tests/glr-regression.at (Leaked semantic values when reporting
10084 ambiguity): New test case.
10085 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
10086 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
10087 now unnecessary yystackp parameter.
10088 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
10089 destructors can be called.
10091 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
10092 in existing testcases.
10094 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
10096 Don't leak semantic values for parent RHS when a user action cuts the
10097 parser, and clean up related code a bit.
10098 * tests/glr-regression.at (Leaked merged semantic value if user action
10099 cuts parse): Rename to...
10100 (Leaked semantic values if user action cuts parse): ... this. Add check
10101 for leaked parent RHS values.
10102 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
10103 between an unresolved state (non-empty chain of semantic options) and
10104 an incomplete one (signaled by an empty chain).
10105 (yyresolveStates): Document the interface. Move all manipulation of a
10106 successfully or unsuccessfully resolved yyGLRState to...
10107 (yyresolveValue): ... here so that yyresolveValue always leaves a
10108 yyGLRState with consistent data and thus is easier to understand.
10109 Remove the yyvalp and yylocp parameters since they are always just
10110 taken from the yys parameter. When reporting a discarded merged value
10111 in debugging output, note that it is incompletely merged. Document the
10113 (yyresolveAction): If resolving any of the RHS states fails, destroy
10114 them all rather than leaking them. Thus, as long as user actions are
10115 written to clean up the RHS correctly, yyresolveAction always cleans up
10116 the RHS of a semantic option. Document the interface.

10182 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
10183 nodist_PROGRAMS, since we don't need to actually compile the
10184 example if we're just doing a plain 'make'. This avoids bothering

10235 During deterministic GLR operation, user actions should be able to
10236 influence the parse by changing yychar. To make this easier to fix and
10237 to make glr.c easier to evolve in general, don't maintain yytoken in

10245 yychar rather than *yytokenp to determine the current lookahead.

10265 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
10266 got from <http://bro-ids.org/download.html>. The bug is that
10267 when two actions appeared in succession, the second one was
10268 scanned before the first one was added to the grammar rule
10269 as a midrule action. Bison then output the incorrect warning
10270 "parse.y:905.17-906.36: warning: unused value: $3".

10290 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
10291 All used changed. Check whether the symbol has a destructor,
10292 not whether it is typed.

10294 that the values are still reported as unused. All line numbers

10341 since we don't want to insist on a version number at the start
10342 of the changelog every time.
10343 * Makefile.maint: Sync from coreutils a bit better.

10499 with "file system".

10512 yynewLookaheadNeeds.
10513 * data/glr-regression.at (Incorrect lookahead during nondeterministic

10520 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10522 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
10524 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>

10529 (Actions): Mention look-ahead usage of yylval.
10530 (Actions and Locations): Mention look-ahead usage of yylloc.
10531 (Special Features for Use in Actions): Add YYEOF entry and mention it
10532 in the yychar entry.
10533 In the yychar entry, remove mention of the local yychar case (pure
10534 parser) since this is irrelevant information when writing semantic
10535 actions and since it's already discussed in `Table of Symbols' where
10536 yychar is otherwise described as an external variable.
10537 In the yychar entry, don't call it the `current' look-ahead since it
10538 isn't when semantic actions are deferred.
10539 In the yychar and yyclearin entries, add note about deferred semantic
10541 Add yylloc and yylval entries discussing look-ahead usage.
10542 (Look-Ahead Tokens): When discussing yychar, don't call it the
10543 `current' look-ahead, and do mention yylval and yylloc.
10544 (Error Recovery): Cross-reference `Action Features' when mentioning
10546 (Table of Symbols): In the yychar entry, don't call it the `current'
10548 In the yylloc and yylval entries, mention look-ahead usage.
10550 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
10552 * tests/glr-regression.at: Update copyright year to 2006.
10554 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10556 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
10557 use during nondeterministic operation to track which stacks have
10558 actually needed the current lookahead.
10559 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
10560 Allocate, deallocate, resize, and otherwise shuffle space for
10561 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
10562 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
10563 appropriately during nondeterministic operation.
10564 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
10565 members to store the current lookahead to be used by the deferred
10567 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
10568 from which the RHS is taken. Set the lookahead members of the new
10569 yySemanticOption according to the lookahead status for stack yyk.
10570 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
10571 yyaddDeferredAction.
10572 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
10573 members of yySemanticOption before invoking yyuserAction, and then set
10574 them back to their current values afterward.
10575 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
10576 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
10577 * tests/glr-regression.at: Remove `.' from the ends of recent test case
10578 titles for consistency.
10579 (Leaked merged semantic value if user action cuts parse): In order to
10580 suppress lint warnings, use arguments in merge function, and assign
10581 char value < 128 in main.
10582 (Incorrect lookahead during deterministic GLR): New test case.
10583 (Incorrect lookahead during nondeterministic GLR): New test case.

10590 to print a semantic value.
10592 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
10594 * tests/glr-regression.at: For consistency with my newer test cases,
10595 don't thank myself.
10597 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
10599 * data/glr.c (yyresolveValue): When merging semantic options, if at
10600 least one user action succeeds but a later one cuts the parse, then
10601 destroy the semantic value before returning rather than leaking it.
10602 (yyresolveStates): If a user action cuts the parse and thus
10603 yyresolveValue fails, ignore the (unset) semantic value rather than
10604 corrupting the yyGLRState, and empty the semantic options list since
10605 the user actions should have called all necessary destructors.
10606 Simplify code with YYCHK.
10607 * tests/glr-regression.at (Corrupted semantic options if user action
10608 cuts parse): New test case.
10609 (Undesirable destructors if user action cuts parse): New test case.
10610 Before applying any of this patch, this test case never actually failed
10611 for me... but only because the corrupted semantic options usually

10655 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
10656 about declarations in the grammar when in Yacc mode, as POSIX does
10657 not require a diagnostic when the grammar uses extensions.
10659 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
10661 Warn about dubious constructions like "%token T T".
10662 Reported by twlevo.

10683 Have glr.cc pass (some of) the calc.at tests.
10684 * data/glr.cc (b4_parse_param_orig): New.
10685 (b4_parse_param): Improve its definition, and bound it more
10686 clearly in the skeleton.
10687 (b4_epilogue): Append, instead of prepending, in order to keep
10689 Simplify the generation of auxiliary functions: locations and
10690 purity are mandated.
10691 (b4_global_tokens_and_yystype): Honor it.

10729 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
10730 (rule_length_overflow, increment_rule_length, add_column_width):
10732 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
10733 (<SC_BRACED_CODE>"}"):
10734 Use increment_rule_length rather than incrementing it by hand.

10737 Fix bug with monstrosities like $-2147483648.
10738 Remove now-unnecessary checks.
10739 (scan_integer): Verify assumptions and remove now-unnecessary checks.

10741 (handle_syncline): New arg LOC. All callers changed.
10742 Don't store through a value derived from char const * pointer.
10744 * src/reader.c (grammar_rule_check): Rewrite slightly to avoid
10747 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
10749 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
10750 Remove unnecessary forward static decls.

10762 * tests/torture.at (input): Don't rely on the default action
10763 being always performed.
10764 * tests/calc.at: "Set" $$ even when the action is "cut" with

10767 values, check that the warning is issued.
10769 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
10771 * NEWS: Improve wording for unused-value warnings.
10773 2005-12-22 Akim Demaille <akim@epita.fr>
10775 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4

10806 Undo 2005-12-01 tentative license wording change. The wording is
10807 still being reviewed by the lawyers, and we don't want to wait for
10808 them before publishing a test release. For now, revert to the

10830 * tests/cxx-type.at: Construct a tree, count the parents of shared
10831 nodes, and free each node once and only once. Previously, the memory
10832 for semantic values was leaked instead.
10834 2005-12-21 Joel E. Denny <address@hidden>
10836 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
10837 (yylval, yylloc): If pure, #define to yystackp->yyval and
10838 yystackp->yyloc similar to yychar and yynerrs.
10839 (yyparse): If pure, remove local yylval and yylloc. Add local
10840 yystackp to accommodate pure definitions of yylval and yylloc.
10841 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
10842 yylvalp and yyllocp to &yylval and &yylloc.
10843 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]

10846 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
10847 yylvalp and yyllocp parameters since, if pure, these are now always
10848 accessible through yystackp. If not pure, they are still accessible
10850 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
10851 `if (YYID (N))' to pacify lint.
10853 2005-12-21 Akim Demaille <akim@epita.fr>
10855 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
10856 destroy the RHS symbols of a rule.
10857 * data/yacc.c (yylen): Initialize to 0.
10858 Keep its value to the number of items to possibly shift.
10859 In particular, a regular successful parse that ends on YYFINAL by
10860 a (internal) YYACCEPT must not have yylen != 0.
10861 (yyerrorlab, yyreturn): Pop the RHS.
10862 Reorder a bit to emphasize the `shifting' bits of code.

10874 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
10875 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.

10906 * tests/sets.at (Accept): Fix typos in regular expression used to
10907 sed out the final state number.
10909 Work around portability problem on Solaris 10: flex-generated
10910 files include <stdio.h> before <config.h>, which messes up
10911 because the latter defines __EXTENSIONS__. Address the problem
10912 by creating two new little files that include <config.h> first,
10913 then include the flex-generated files. Rewrite everyone else
10914 to include <config.h> first, as well.
10915 * lib/timevar.c: Always include "config.h".

10953 Cleanups so that Bison-generated parsers have less lint.
10954 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
10955 Prepend /*ARGSUSED*/, for lint's sake.
10956 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
10957 definition if 'lint' is defined.
10958 (YYID): New macro (or function, if lint).
10959 All uses of /*CONSTCOND*/0 replaced by YYID(0).

10987 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
10989 * NEWS: Document the following change.
10990 * data/yacc.c: Say "parser skeleton" rather than "file", since
10991 it's no longer just a file.

11123 2005-11-03 Akim Demaille <akim@epita.fr>

11256 Undo the parts of the unlocked-I/O change that substituted

11260 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

11289 Use unlocked I/O for a minor performance improvement on hosts like
11290 GNU/Linux and Solaris that support unlocked I/O. The basic idea
11291 is to use the gnlib unlocked-io module, and to prefer putc and

11365 to allow support for non-posix systems. This is a no-op function
11368 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
11369 handle the lack of pipe/fork functionality on non-posix systems.

11462 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
11463 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
11464 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
11465 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
11466 to match yacc.c, to test more hosts.
11468 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
11470 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
11471 doesn't affect behavior.
11472 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
11474 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
11475 This works a bit better with glibc, if user code has already included
11477 * doc/bison.texinfo (Bison Parser): Document that users can't
11478 arbitrarily use malloc and free for other purposes. Document
11479 that <alloca.h> and <malloc.h> might be included.
11480 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
11481 user must declare alloca.
11483 * HACKING (release): Forwarn the Translation Project about
11486 2005-09-20 Akim Demaille <akim@epita.fr>

11492 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
11493 (YYSTACK_ALLOC_MAXIMUM): Use it.
11494 (yysyntax_error): New function.
11495 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
11496 multiple syntax errors are reported, and alloca is being used.
11497 Instead, reallocate buffers twice as big each time, so that
11498 we waste at most half the allocated memory. Start with a small
11499 (128-byte) buffer that will suffice in most cases anyway.
11500 Use yysyntax_error to do most of the work.
11502 * doc/bison.texinfo (Error Reporting, Table of Symbols):
11503 yynerrs is the number of errors reported, not the number of
11504 errors encountered.
11506 * tests/glr-regression.at (Duplicated user destructor for lookahead):
11507 Mark it as expected to fail.
11508 Cast result of malloc; problem reported by twlevo@xs4all.nl.
11509 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
11510 Don't start user-code symbols with "yy", to avoid name space problems.
11512 2005-09-19 Akim Demaille <akim@epita.fr>
11514 Remove the traits, failed experiment.
11515 It never proved useful, and anyway because of the current
11516 definition, it was not possible to have several specialization of
11517 this traits, making it useless.
11518 * data/lalr1.cc (yy:traits): Remove.
11519 Inline its definitions in the parser class.
11521 2005-09-19 Akim Demaille <akim@epita.fr>

11528 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
11529 and yytoken for similarity with the other skeletons.
11531 2005-09-19 Akim Demaille <akim@epita.fr>
11533 * NEWS, configure.ac: update version number to 2.1a.

11543 * src/output.c (prepare): Likewise.
11544 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
11545 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
11546 is not defined. This is an awful hack, but it's enough for now.
11547 All callers changed.
11548 * tests/glr-regression-at (make_value): Args are const pointers now,
11549 to avoid GCC warning.
11550 (Duplicated user destructor for lookahead): New test. Currently
11551 skipped. It fails on my host but I'm not sure it'll always fail.
11553 2005-09-16 Akim Demaille <akim@epita.fr>
11555 * src/symtab.h (struct symbol): Declare the printer and destructor
11556 as const, to avoid accidental calls to free.
11557 (symbol_destructor_set, symbol_printer_set): Adjust.
11558 * src/symtab.c: Adjust.
11560 2005-09-16 Akim Demaille <akim@epita.fr>
11562 * data/c.m4 (b4_token_enums): New.
11563 (b4_token_defines): Rename as...
11564 (b4_token_enums_defines): this.
11565 (b4_token_defines): New, output only the #defines.
11566 * data/yacc.c, data/glr.c: Adjust.
11567 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
11568 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
11571 2005-09-16 Akim Demaille <akim@epita.fr>
11573 * data/lalr1.cc (yylex_): Remove, inline its code.
11574 (yyreport_syntax_error_): Remove, replaced by...
11575 (yysyntax_error_): this which returns a string and leaves to the
11576 caller the call to the users' error function.
11577 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
11578 Move from members of the parser object...
11579 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
11580 to local variables of the parse function.
11582 2005-09-16 Akim Demaille <akim@epita.fr>
11584 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
11585 since it's in Bison's name space.
11587 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
11589 * data/glr.c (yyresolveValue): Add default case to pacify
11590 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
11592 * NEWS: Document when yyparse started to return 2.
11593 * doc/bison.texinfo (Parser Function): Document when yyparse
11596 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
11597 (b4_filename_type): Renamed back from b4_file_name_type. All uses
11599 (class position): file_name -> filename (reverting). All uses changed.
11601 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
11603 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
11604 do anything if $@ exists. This reverts part of the 2005-07-07
11607 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
11609 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
11610 contains obsolete information and isn't worth distributing as a
11611 separate file anyway.
11612 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
11613 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
11614 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
11615 (yyparse): Abort if user code uses longjmp to throw an unexpected
11618 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
11620 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
11621 Suggested by twlevo@xs4all.nl.
11623 * data/glr.c (YYCHK1): Do not assume YYE is in range.
11624 This avoids a diagnostic from gcc -Wswitch-enum.
11625 Problem reported by twlevo@xs4all.nl.
11627 * doc/bison.texinfo: Don't use "filename", as per GNU coding
11628 standards. Use "file name" or "file" or "name", depending on
11630 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
11631 not to hack/foo.tab.c.
11632 (Calc++ Top Level): 2nd arg of main is not const.
11633 * data/glr.c: b4_filename -> b4_file_name.
11634 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
11636 (class position): filename -> file_name. All uses changed.
11637 * data/yacc.c: b4_filename -> b4_file_name.
11638 * lib/bitset.h: filename -> file_name in local vars.
11639 * lib/bitset_stats.c: Likewise.
11640 * src/files.c: Likewise.
11641 * src/scan-skel.l ("@output ".*\n): Likewise.

11648 to accommodate latest gnulib.
11650 * tests/glr-regression.at (Duplicate representation of merged trees):
11651 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
11653 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
11656 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11658 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
11659 All uses changed. Invoke user destructor after an error during a
11660 split parse (trivial change from Joel E. Denny).
11662 * tests/glr-regression.at
11663 (User destructor after an error during a split parse): New test case.
11664 Problem reported by Joel E. Denny in:
11665 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
11667 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11669 * README-cvs: Give URLs for recommended tools.
11670 Mention Gzip version problem, and bootstrapping issues.
11671 Remove troubleshooting section, as it's somewhat obsolete.
11673 * bootstrap (no_cache): New var, to accommodate different wget
11674 variants. Use it instead of '-C off'. Problem reported by
11677 * data/glr.c (yydestroyStackItem): New function.
11678 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
11679 debugging information. Problem reported by Joel E. Denny.
11681 2005-08-25 Akim Demaille <akim@epita.fr>
11683 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.

11692 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
11694 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
11696 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
11698 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
11699 lib-prefix.m4, po.m4.
11701 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
11702 in yydestruct diagnostic, since it might not be an error.
11703 Problem reported by Joel Denny near end of
11704 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
11705 * data/lalr1.cc (yyerturn): Likewise.
11706 * data/yacc.c (yyreturn): Likewise.
11707 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
11709 * src/files.c: Remove obsolete FIXME comment.
11711 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
11712 with the other templates, and to fix bogus run-on messages such
11713 as the one reported at the end of
11714 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
11715 All callers changed to avoid the newline.
11716 (yyprocessOneStack): Output two lines rather than one, to accommodate
11717 the above change. This changes the debug output format slightly.
11719 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
11720 reported by Joel E. Denny in
11721 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
11723 * tests/glr-regression.at (Duplicate representation of merged trees):
11724 New test, from Joel E. Denny in:
11725 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
11726 * THANKS: Add Joel E. Denny.

11730 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
11732 * NEWS: Version 2.0b.
11734 * Makefile.am (SUBDIRS): Put examples before tests, so that
11735 "make check" doesn't finish with "All 1 tests passed".
11737 * tests/regression.at (Token definitions): Don't rely on
11738 AT_PARSER_CHECK for data that contains backslashes. It currently
11739 uses 'echo', and 'echo' isn't portable if its argument contains
11740 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
11741 that the byte '\0xff' is not printable in the C locale; it is,
11742 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
11743 not printable, so use '\0x81' to test.
11745 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
11746 version of GCC, since the macro is used with non-GCC compilers.
11748 Fix core dump reported by Pablo De Napoli in
11749 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
11750 * tests/regression.at (Invalid inputs with {}): New test.
11751 * src/parse-gram.y (token_name): Translate type before using
11754 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
11755 the user's name space. All uses changed to __attribute__
11757 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
11758 Add __attribute__ ((__noreturn__)).
11760 * etc/clcommit: Remove. We weren't using it, and it failed
11761 "make maintainer-distcheck".
11762 * Makefile.maint: Merge from coreutils.
11763 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
11764 (syntax-check-rules): Change list of rules as described below.
11765 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
11766 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):

11771 (sc_space_tab, sc_error_exit_success, sc_changelog):
11772 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
11773 (makefile-check, po-check, author_mark_check):
11774 (makefile_path_separator_check, copyright-check):
11775 Use grep -n, to make it easier to find violations.
11776 Use CVS_LIST and CVS_LIST_EXCEPT.
11777 (header_regexp, h_re): Remove.
11779 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
11780 (my-distcheck): Use more-modern GCC flags.
11781 (signatures, %.asc): Remove.
11782 (rel-files, announcement): Remove signatures.
11783 Restore old updating code, even though we don't use it, so
11784 that we're the same as coreutils.
11785 (alpha, beta, major): Depend on news-date-check.
11786 Make the upload commands.
11788 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

11795 * tests/sets.at: Likewise.
11797 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
11798 we comment out the Autoconf version number.
11799 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
11800 it's error-prone and "make maintainer-distcheck" rejects it.
11802 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
11803 Indent calls to "error" to pacify "make maintainer-distcheck",
11804 when the calls are not intended to be translated.
11805 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
11807 * src/Makefile.am (DEFS): Use +=, to pacify
11808 "make maintainer-distcheck".
11809 (bison_SOURCES): Add scan-skel.h.
11810 (sc_tight_scope): New rule, from coreutils.
11812 * src/files.c (src_extension, header_extension):
11813 Now static, not extern.
11814 * src/getargs.c (short_options): Likewise.
11815 * src/muscle_tab.c (muscle_table): Likewise.
11816 * src/parse-gram.y (current_class, current_type, current_prec):
11818 * src/reader.c (grammar_end, previous_rule_end): Likewise.
11819 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
11820 * src/main.c (main): Cast bindtextdomain and textdomain calls to
11821 void, to avoid warning when NLS is disabled.
11822 * src/output.c: Include scan-skel.h.
11823 (scan_skel): Remove decl, since scan-skel.h does this.
11825 Indent calls to "error" to pacify "make maintainer-distcheck".
11826 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
11827 * src/reader.h (gram_end, gram_lineno): New decls to pacify
11828 "make maintainer-distcheck".
11829 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
11830 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
11831 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
11832 (skel_lex_destroy, scan_skel): Move these decls to...
11833 * src/scan-skel.h: New file.
11834 * src/uniqstr.c (uniqstr_assert):
11835 Indent calls to "error" to pacify "make maintainer-distcheck".
11837 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
11840 * tests/torture.at: Revamp to avoid misuse of atoi that
11841 "make maintainer-distcheck" complained about.
11843 * examples/extexi (message): Don't print a message more than once,
11844 and omit line-number decoration that makes Emacs compile think
11845 that informative messages are worth worrying about.
11847 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
11849 * configure.ac: Update version number.
11851 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
11853 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
11854 autogenerated by the maintainer.
11855 * examples/calc++/.cvsignore: Add *.yy.
11857 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
11858 * lib/bitset_stats.c (bitset_stats_init): Likewise.
11859 * lib/bitsetv.c (bitsetv_alloc): Likewise.
11861 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
11863 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
11864 from maintainer-distcheck about casting the argument of 'free'.
11866 * NEWS: Mention recent yytname changes.
11867 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
11869 * bootstrap: For translations that have not yet been upgraded to
11870 the new runtime-po domain, prime the pump by extracting the
11871 relevant strings from the obsolete translations. This code can be
11872 removed once the bison-runtime domain has been translated by each
11875 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
11876 now that token names are already quoted.
11878 Fix problem reported by Anthony Heading.
11879 * data/glr.c (YYTOKEN_TABLE): New macro.
11880 (yytname): Define if YYTOKEN_TABLE.
11881 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
11882 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
11883 (YYERROR_VERBOSE): Define the same way the other skeletons do.
11884 * src/output.c (prepare_symbols): Output token_table_flag.
11886 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
11888 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
11889 again if the first call fails.
11891 * data/glr.c (yytnamerr): New function.
11892 (yyreportSyntaxError): Use it to dequote most string literals.
11893 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
11894 with other skeletons. All uses changed.
11895 (yytnameerr_): New function.
11896 (yyreport_syntax_error): Use it to dequote most string literals.

11899 * doc/bison.texinfo (Decl Summary, Calling Convention):
11900 Clarify quoting convention of yytname.
11901 * src/output.c (prepare_symbols): Quote all names. This undoes
11902 the 2005-04-17 change, which is now accomplished (mostly) via
11903 changes in the parsers as described above.
11904 * tests/regression.at (Token definitions, Web2c Actions):
11905 Undo most 2005-04-17 change here, too.
11907 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
11909 Fix more problems reported by twlevo@xs4all.nl.
11910 * tests/cxx-type.at: Don't pipe output of ./types through sed to
11911 remove trailing spaces. This loses the exit status of ./types,
11912 and isn't needed since ./types shouldn't be emitting trailing
11914 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
11915 as the stack isn't valid in that case.
11917 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
11918 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
11919 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
11920 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
11922 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
11923 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
11924 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
11927 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
11928 overly-picky compilers that reject 'char *foo = "bar";'.
11930 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
11931 to FILE * parameter, not to stderr. This fixes a typo introduced
11932 in the 2005-07-12 change.
11934 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
11935 warnings from GCC 4.
11937 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
11938 (yyglrShiftDefer, yysplitStack):
11939 Remove unused parameters b4_pure_formals. All uses changed.
11940 (yyglrShift): Remove unused parameters b4_user_formals.
11942 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
11944 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
11946 Destructor cleanups and regularization among the three skeletons.
11947 * NEWS: Document the behavior changes.
11948 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
11949 stack before failing, as the cleanup code will do it for us now.
11950 * data/lalr1.cc (yyerrlab): Likewise.
11951 * data/glr.c (yyparse): Pop everything off the stack before
11952 freeing it, so that destructors get called properly.
11953 * data/lalr1.cc (yyreturn): Likewise.
11954 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
11955 This is more consistent.
11956 * doc/bison.texinfo (Destructor Decl): Mention more reasons
11957 why destructors might be called. 1.875 -> 2.1.
11958 (Destructor Decl, Decl Summary, Table of Symbols):
11959 Some English-language cleanups for %destructor.
11960 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11961 Add output line for destructor of start symbol.
11962 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
11963 because of that same extra output line.
11965 * NEWS: Document minor wording changes in diagnostics of
11966 Bison-generated parsers.
11967 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
11968 Remove unused formals. All uses changed.
11969 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
11970 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
11971 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
11972 Rename yyoverflowab to yyexhaustedlab.
11973 When memory exhaustion occurs during syntax-error reporting,
11974 report it separately rather than in a single diagnostic; this
11976 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
11977 (Memory Exhausted): Renamed from Parser Stack Overflow.
11978 Revamp wording slightly to prefer "memory exhaustion".
11979 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
11981 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
11983 Add i18n support to the GLR skeleton. Partially fix the C++
11984 skeleton; a C++ expert needs to finish this. Remove debugging
11985 msgids; there's little point to having them translated, since they
11986 can be understood only by someone who can read the
11987 (English-language) source code.
11989 Generate runtime-po/bison-runtime.pot automatically, so that we
11990 don't have to worry about garbage getting in that file. We'll
11991 make sure after the next official release that old msgids don't
11993 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
11995 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
11996 Now auto-generated.
11997 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
11998 Fix typos in explanations of the runtime file.
11999 * bootstrap: Change gettext keyword from YYI18N to YY_.
12000 Use standard Makefile.in.in in runtime-po, since we'll arrange
12001 for backward-compatible bison-runtime.po files in a different way.
12002 * data/glr.c (YY_): New macro, from yacc.c.
12003 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
12004 Translate messages intended for users.
12005 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
12006 the wording in the other skeletons. We don't know that the memory
12008 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
12009 Use same method that yacc.c uses.
12010 Don't translate debugging messages.
12011 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
12012 it doesn't work (yet), and requires C++ expertise to fix.
12013 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
12014 Move defn to a more logical place, to be consistent with other
12016 Don't translate debugging messages.
12017 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
12018 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
12019 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
12020 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
12022 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
12023 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
12025 * tests/glr-regression.at (Badly Collapsed GLR States):
12027 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
12028 yylex should return 0 at EOF rather than aborting.
12030 Improve tests for stack overflow in GLR parser.
12031 Problem reported by twlevo@xs4all.nl.
12032 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
12034 (yyStackOverflow): Just longjmp, but with value 2 so that caller
12035 can handle the problem.
12036 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
12037 (yyparse): New local variable yyresult to record the result.
12038 Use result of setjmp to set it, rather than storing itinto
12040 (yyDone): Remove label.
12041 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
12042 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
12043 if YYABORT is used).
12044 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
12045 yyparse status; put status > 1 into diagnostic.
12046 Check that status==2 works.
12047 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
12048 Use exit status 3 for failure to open (which shouldn't happen).
12050 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
12052 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
12053 1 on syntax error; just let yyparse do its thing.
12054 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
12055 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
12056 (Exploding the Stack Size with Alloca):
12057 (Exploding the Stack Size with Malloc):
12058 Expect exit status 2, not 1, since the parser is supposed to blow
12059 its stack. Problem reported by twlevo@xs4all.nl.
12061 * data/glr.c (yyparse): Don't assume that the initial calls
12062 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
12063 Print a stack-overflow message and fail instead.
12064 Initialize the line-number information before creating the stack,
12065 so that the stack-overflow message can report line zero safely.
12067 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
12069 Fix problems reported by twlevo@xs4all.nl.
12070 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
12071 (yyuserMerge): Provide a default case if b4_mergers is empty.
12072 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
12073 * tests/glr-regression.at
12074 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
12075 Add casts to pacify C++ compilers.
12076 * tests/glr-regression.at (Improper merging of GLR delayed action
12077 sets): Declare yylex before using it.
12078 * tests/Makefile.am (maintainer-check-g++): Fix a stray
12079 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
12080 test for valgrind; valgrind is independent of g++.
12081 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
12082 for compatibility with POSIX 1003.1-2001 (if running coreutils).
12083 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
12084 Use a destructor, so that we can expand the stack. Change
12085 YYSTYPE to char * so that we can free it. Cast result of malloc.
12087 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12089 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
12090 a valgrind failure. Problem reported by twlevo@xs4all.nl.
12092 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
12094 * PACKAGING: New file, suggested by Bruno Haible and taken from
12095 similar wording in gettext's PACKAGING file.
12096 * NEWS: Mention PACKAGING.
12097 * Makefile.am (EXTRA_DIST): Add PACKAGING.
12099 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
12101 * NEWS: Document recent i18n improvements.
12102 * bootstrap: Get runtime translations into runtime-po.
12103 Create runtime-po files automatically, if possible.
12104 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
12105 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
12106 does not infringe on the user's name space.
12107 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
12108 * doc/bison.texinfo (Internationalization): Revamp the English
12109 and Texinfo syntax a bit, to try to make it clearer.
12110 (Bison Options, Option Cross Key): Mention --print-localedir.
12111 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
12112 YYENABLE_NLS. Quote a bit more.
12113 * runtime-po/.cvsignore: New file.
12114 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
12115 * runtime-po/Rules-quot: Remove; now created by bootstrap.
12116 * runtime-po/quot.sed: Likewise.
12117 * runtime-po/boldquot.sed: Likewise.
12118 * runtime-po/en@quot.header: Likewise.
12119 * runtime-po/en@boldquot.header: Likewise.
12120 * runtime-po/insert-header.sin: Likewise.
12121 * runtime-po/remove-potcdate.sin: Likewise.
12122 * runtime-po/Makevars: Likewise.
12123 * runtime-po/LINGUAS: Likewise.
12124 * runtime-po/de.po: Likewise; we will rely on the translation project
12125 to maintain this, so "bootstrap" should get it.
12126 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
12128 * src/main.c (main): Bind the bison-runtime domain, too.
12130 2005-07-12 Bruno Haible <bruno@clisp.org>
12132 * data/yacc.c: Include <libintl.h> when NLS is enabled.
12133 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
12134 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
12135 * runtime-po: New directory.
12136 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
12137 $(DOMAIN).pot-update rule, so that old messages are never dropped.
12138 * runtime-po/Rules-quot: New file, copied from po/.
12139 * runtime-po/quot.sed: Likewise.
12140 * runtime-po/boldquot.sed: Likewise.
12141 * runtime-po/en@quot.header: Likewise.
12142 * runtime-po/en@boldquot.header: Likewise.
12143 * runtime-po/insert-header.sin: Likewise.
12144 * runtime-po/remove-potcdate.sin: Likewise.
12145 * runtime-po/Makevars: New file.
12146 * runtime-po/POTFILES.in: New file.
12147 * runtime-po/LINGUAS: New file.
12148 * runtime-po/bison-runtime.pot: New file.
12149 * runtime-po/de.po: New file.
12150 * m4/bison.m4: New file.
12151 * Makefile.am (SUBDIRS): Add runtime-po.
12152 (aclocaldir, aclocal_DATA): New variables.
12153 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
12155 * src/getargs.c (usage): Document --print-localedir option.
12156 (PRINT_LOCALEDIR_OPTION): New enum item.
12157 (long_options): Add --print-localedir option.
12158 (getargs): Handle --print-localedir option.
12159 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
12160 (Internationalization): New section.
12162 2005-07-12 Akim Demaille <akim@epita.fr>
12164 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
12165 for consistency with the rest of the code.
12166 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
12169 2005-07-12 Akim Demaille <akim@epita.fr>
12171 * src/parse-gram.y: Use %printer instead of YYPRINT.
12173 2005-07-12 Akim Demaille <akim@epita.fr>
12175 * src/symtab.h, src/symtab.c (symbol_print): New.
12176 * src/symlist.h, src/symlist.c (symbol_list_print): New.
12177 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
12179 2005-07-12 Akim Demaille <akim@epita.fr>
12181 * data/glr.c (b4_syncline): Fix (swap) the definitions of
12182 b4_at_dollar and b4_dollar_dollar.
12184 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
12186 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
12187 and Pennello's paper.
12189 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
12191 * data/yacc.c (yyparse): Undo previous patch. Instead,
12192 set yylsp[0] and yyvsp[0] only if the initial action
12193 sets yylloc and yylval, respectively.
12195 * data/yacc.c (yyparse): In the initial action, set
12196 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
12197 This avoids the use of undefined variables if the initial
12198 action does not set yylloc and/or yylval.
12200 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12202 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
12203 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
12204 Remove from CVS. These files are automatically generated.
12205 * examples/extexi: Clarify that this file is now part of Bison,
12206 not GNU M4, and that it works with any POSIX-compatible Awk.
12207 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
12208 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
12209 so that we also get calc++-parser.yy. Geneate it.
12210 Use $(AWK), not gawk, since any conforming Awk will do.
12211 Put comment before action, since older 'make' can't handle comment
12213 $(BUILT_SOURCES): List all built sources, not just some of them.
12214 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
12215 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
12216 $($(calc_sources_generated)): Remove unnecessary test for existence
12217 of target. (This had a shell syntax error anyway; a stray "x".)
12218 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
12220 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
12222 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
12223 implied by the other modules.
12225 2005-07-06 Akim Demaille <akim@epita.fr>
12227 Bind examples/calc++ to the package.
12228 * examples/calc++/Makefile: Remove, replaced by...
12229 * examples/calc++/Makefile.am: ... this new file.
12230 * examples/calc++/test: Remove input.
12231 * examples/calc++/compile: Remove.
12232 * examples/Makefile.am: New.
12233 * configure.ac, Makefile.am: Adjust.

12236 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
12238 * data/glr.c (yyFail): Drastically simplify; since the format argument
12239 never had any % directives, we can simply pass it to yyerror.
12240 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
12241 be modified later, as that is the usual style in glr.c.
12242 Problems reported by Paul Hilfinger.
12244 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
12245 and size overflow errors.
12246 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
12247 in case the user prolog sets feature-test macros like _GNU_SOURCE.
12248 (YYSIZEMAX): New macro.
12249 (yystpcpy): New function, taken from yacc.c.
12250 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
12251 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
12252 so that we don't have to maintain their signatures.
12253 (yyFail): Check for buffer overflow, by using vsnprintf rather
12254 than vsprintf. Allocate a bigger buffer if possible.
12255 Report an error if buffer allocation fails.
12256 (yyStackOverflow): New function.
12257 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
12258 the initialization was successful. It might fail if storage was
12260 (yyexpandGLRStack): Add more checks for storage allocation failure.
12261 Use yyStackOverflow to report failures.
12262 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
12263 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
12264 Don't assume stack number fits in int.
12265 (yysplitStack): Check for storage allocation failure.
12266 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
12267 can print diagnostics on storage allocation failure. All callers
12269 (yyresolveValue): Use yybool for boolean.
12270 (yyreportSyntaxError): Check for size-calculation overflow.
12271 This code is taken from yacc.c.
12272 (yyparse): Check for storage allocation errors when allocating
12275 2005-07-05 Akim Demaille <akim@epita.fr>
12277 Extract calc++ from the documentation.
12278 * doc/bison.texinfo (Calc++): Add the extraction marks.
12279 * examples/extexi: New, from the aborted GNU Programming 2E.
12280 Separate the different paragraph of a file with empty lines.
12281 * examples/Makefile: Use it to extract the whole calc++ example.
12283 2005-06-24 Akim Demaille <akim@epita.fr>
12285 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
12288 2005-06-22 Akim Demaille <akim@epita.fr>
12290 * doc/bison.texinfo (C++ Language Interface): First stab.
12291 (C++ Parsers): Remove.
12293 2005-06-22 Akim Demaille <akim@epita.fr>
12295 * data/lalr1.cc (yylex_): Honor %lex-param.
12297 2005-06-22 Akim Demaille <akim@epita.fr>
12299 Start a set of simple examples.
12300 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
12301 * examples/calc++/calc++-driver.hh,
12302 * examples/calc++/calc++-parser.yy,
12303 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
12304 * examples/calc++/compile, examples/calc++/test: New.
12306 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
12308 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
12309 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
12310 which stems from the 2005-05-27 patch.
12312 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
12314 * data/glr.c: Modify treatment of unused parameters to permit use
12315 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
12317 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
12319 Fix infringement on user name space reported by Janos Zoltan Szabo.
12320 * data/yacc.c (yyparse): strlen -> yystrlen.
12322 2005-05-30 Akim Demaille <akim@epita.fr>
12324 * data/lalr1.cc (_): New.
12325 Translate the various messages.
12327 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
12329 Fix infringement on user name space reported by Bruno Haible.
12330 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
12331 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
12332 the user's name space.
12333 (alloca): Include <stdlib.h> to get it, if it's not built in.
12334 (YYMALLOC, YYFREE): Define only if needed.
12335 (malloc, free): Declare, but only if needed, as this infringes on
12336 the user name space.
12338 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12340 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
12341 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
12343 * lib/ebitset.c (min, max): Undef before defining.
12344 * lib/vbitset.c (min, max): Likewise.
12345 * lib/subpipe.c (create_subpipe): Save local variables in case
12346 vfork clobbers them.
12348 2005-05-24 Bruno Haible <bruno@clisp.org>
12350 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
12351 error message syntax used by gcc-4.0.
12353 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
12355 * README: Mention m4 1.4.3. Remove obsolete advice about
12356 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
12358 * bootstrap: Remove workaround for problem I encountered with
12359 gettext 0.14.1; it seems to be fixed now.
12361 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
12363 * NEWS: Version 2.0a.
12365 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
12366 the previous change.
12368 Various maintainer cleanups.
12369 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
12370 conftest*, for benefit of CVS commands run at the same time as
12371 "configure". Add build-aux, since "bootstrap" now creates it and
12373 * Makefile.cfg (move_if_change): Remove.
12374 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
12375 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
12376 (po_repo, do-po-update, po-update, wget_files, get-targets):
12377 (config.guess-url_prefix, config.sub-url_prefix):
12378 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
12379 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
12380 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
12382 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
12383 this is now the recommended name.
12384 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
12385 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
12386 ylwrap. These files now go into build-aux.
12387 * config/move-if-change: Remove.
12388 * config/prev-version.txt: Bump from 1.75 to 2.0.
12390 * bootstrap: Add stdio-safer, unistd-safer modules.
12391 Remove m4/glibc2.m4 (introduced by latest gnulib, but
12393 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
12394 fopen-safer.c, stdio-safer.h, unistd-safer.h.
12395 * lib/subpipe.c: Include "unistd-safer.h".
12396 (create_subpipe): Make sure all the newly-created
12397 file descriptors are > 2, so that diagnostics don't
12398 get sent down them (which might cause Bison to hang, in theory).
12399 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
12400 * src/files.c (xfopen): Use fopen_safer, not fopen.
12402 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
12403 yesterday's yacc.c fix.
12405 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
12407 * data/glr.c, data/lalr1.cc: Update copyright date.
12409 Fix a destructor bug reported by Wolfgang Spraul in
12410 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
12411 * data/yacc.c (yyabortlab): Don't call destructor, and
12412 don't set yychar to EMPTY.
12413 (yyoverflowlab): Don't call destructor.
12414 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
12415 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
12416 since we no longer output the message "discarding lookahead token
12419 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12421 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
12422 fix a small glitch in debugging output.
12423 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
12424 after YY_SYMBOL_PRINT where needed.
12426 (struct yyGLRState): Add some comments.
12427 (struct yySemanticOption): Add some comments.
12428 (union yyGLRStackItem): Add comment.
12430 (yymergeOptionSets): Correct this to properly perform the union,
12431 avoiding infinite reported by Michael Rosien.
12434 * tests/glr-regression.at: Add test for GLR merging error reported

12475 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
12477 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
12478 Problem reported by Ralf Menzel.
12480 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12482 * tests/actions.at: Test that stack overflow invokes destructors.
12483 From Marcus Holland-Moritz.
12484 * data/yacc.c (yyerrlab): Move the code that destroys the stack
12486 (yyreturn): to here. That way, destructors are called properly
12487 even if the stack overflows, or the user calls YYACCEPT or
12488 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
12489 (yyoverflowlab): Destroy the lookahead.
12491 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
12493 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
12495 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
12497 * NEWS: Bison-generated C parsers no longer quote literal strings
12498 associated with tokens.
12499 * src/output.c (prepare_symbols): Don't escape strings,
12500 since users don't want to see C escapes.
12501 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
12503 * tests/input.at (Torturing the Scanner): Likewise.
12504 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
12506 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
12508 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
12509 the data size is known to be too small and we can't increase it.
12510 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
12512 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
12514 * src/parse-gram.y: Include quotearg.h.
12515 (string_as_id): Quote $1 before using it as a key, since the
12516 lexer no longer quotes it for us.
12517 (string_content): Don't strip quotes, since lexer no longer
12519 * src/scan-gram.l: Include quotearg.h.
12520 ("\""): Omit quote.
12521 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
12522 a key, since the rest of the lexer doesn't quote it.
12523 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
12524 * tests/regression.at (Token definitions): Check for backslashes
12527 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
12528 (YYSIZE_T): Define to unsigned long int when using an older compiler.
12529 (yyparse): Revamp code to generate long syntax error message, to
12530 make it easier to translate, and to avoid problems with arithmetic
12531 overflow. Change "virtual memory" to "memory" in diagnostic, since
12532 we don't know whether the memory is virtual.
12534 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12536 * NEWS: Bison-generated C parsers now use the _ macro to
12538 * data/yacc.c (_) [!defined _]: New macro.
12539 All English strings wrapped inside this macro.
12540 * doc/bison.texinfo (Bison Parser): Document _.
12541 * po/POTFILES.in: Include src/parse-gram.c, since it now
12542 includes translateable strings that parse-gram.y doesn't.
12544 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
12546 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
12547 reverting the 2004-10-11 change to this function.
12548 (symbol_check_alias_consistency): Don't call symbol_type_set
12549 if the type name is already correct.
12550 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
12552 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
12554 * tests/regression.at (Token definitions): Don't use a token named
12555 c, as that generates a "#define c ..." that runs afoul of buggy
12556 stdlib.h that uses the identifier c as a member of struct
12557 drand48_data. Problem reported by Horst Wente.
12559 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
12561 * bootstrap: Change translation URL from
12562 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
12563 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
12564 redirection glitches. Problem reported by twlevo@xs4all.nl.
12566 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
12568 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
12569 after operands; POSIX says this isn't portable for the c99 command.
12571 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
12573 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
12574 immediately if a data overrun has occurred; this may help us track
12575 down what may be a spurious failure on MacOS.
12577 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
12579 Respond to problems reported by twlevo@xs4all.nl.
12581 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
12583 * src/vcg.h: Comment fix.
12584 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
12585 (G_CMAX): Change to -1 instead of INT_MAX.
12587 * data/yacc.c (yyparse): Omit spaces before #line.
12589 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
12591 * src/tables.c (state_number_to_vector_number): Put it inside an
12592 "#if 0", since it's not currently used. Problem reported by
12595 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
12597 * src/output.c (escaped_output): Renamed from
12598 escaped_file_name_output, since we now use it for symbol tags as
12599 well. All uses changed.
12600 (symbol_destructors_output, symbol_printers_output):
12601 Escape symbol tags too.
12602 Problem reported by Matyas Forstner in
12603 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
12605 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
12607 * src/output.c (user_actions_output, token_definitions_output,
12608 symbol_destructors_output, symbol_printers_output): Likewise.
12609 * src/reader.c (prologue_augment): Likewise.
12610 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
12612 * src/vcg.c (output_edge): Don't quote linestyle arg.
12613 Problem reported by twlevo@xs4all.nl.
12615 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
12617 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
12618 example, reported by Derek M Jones. Also, make the example even
12619 more outrageous, to better illustrate how bad the problem is.
12621 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
12623 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
12624 putsym. Typo reported by Sebastian Piping.
12626 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12628 * doc/bison.texinfo (Language and Grammar): some -> same
12629 (Epilogue): int he -> in the
12630 Typos reported by Sebastian Piping via Justin Pence.
12632 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12634 * tests/glr-regression.at (Improper handling of embedded actions
12635 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
12636 embedded actions and $-N in GLR parsers", work around an Autoconf bug
12637 with dollar signs in test names.
12638 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
12639 for a similar reason.
12641 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12643 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
12644 wants to redefine G_VIEW.
12646 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
12648 * src/vcg.c (get_view_str): Remove case for normal_view.
12649 Problem reported by twlevo@xs4all.nl.
12651 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
12653 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
12654 Problem reported by twlevo@xs4all.nl.
12656 * doc/bison.texinfo: Change @dircategory from "GNU programming
12657 tools" to "Software development". Requested by Richard Stallman
12660 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
12662 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
12663 Problem reported by twlevo@xs4all.nl.
12665 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
12667 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
12668 keyword; it's not needed with modern compilers, and it doesn't
12669 affect correctness with older compilers. Suggested by
12672 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
12674 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
12675 gcc -Wswitch-default.
12676 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
12677 * data/yacc.c (yyparse): Likewise.
12679 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
12681 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
12682 already. Let config.h define any nonstandard values.
12684 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
12686 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
12687 for the benefit of slower hosts. Problem reported by
12688 Nelson H. F. Beebe.
12690 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
12692 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
12693 being defined and not used.
12694 * data/lalr1.cc (yyparse): Likewise.
12695 Use "if (false)" rather than "if (0)".
12697 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
12699 * TODO: Mention that we should allow NUL bytes in tokens.
12701 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
12703 * src/scan-skel.l (<<EOF>>): Don't close standard output.
12704 Problem reported by Hans Aberg.
12706 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
12708 * src/getargs.c (version): Happy new year; update overall
12709 program copyright date from 2004 to 2005.
12711 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
12712 Problem reported by Hans Aberg.
12713 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
12714 (Output file names.): Add a test for the case when standard output
12717 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
12719 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
12720 to fix an oversight in the Bison 2.0 manual.
12722 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
12724 * NEWS: Version 2.0. Reformat the existing news items since
12725 1.875, so that related items are grouped together.
12726 * configure.ac (AC_INIT): Bump version to 2.0.
12727 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
12729 * tests/torture.at (Exploding the Stack Size with Alloca): Set
12730 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
12731 otherwise, we're not testing alloca. Unfortunately there's no
12732 simple way to consult HAVE_ALLOCA here.
12734 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
12737 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
12738 hand. This avoids a warning about comparing int to size_t when
12739 GCC warnings are enabled.
12741 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
12743 * NEWS: Bison-generated parsers no longer default to using the
12744 alloca function (when available) to extend the parser stack, due
12745 to widespread problems in unchecked stack-overflow detection.
12746 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
12747 responsibility to set it to a positive value. This lets the user
12748 specify a value that is not a preprocessor constant.
12749 * data/yacc.c (YYMAXDEPTH): Likewise.
12750 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
12751 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
12752 to be a compile-time constant. However, explain the constraints on it.
12753 Also, explain the constraints on YYINITDEPTH.
12754 (Table of Symbols): Explain that alloca is no longer the default.
12755 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
12758 * doc/bison.texinfo (Location Default Action): Mention that n must
12759 be zero when k is zero. Suggested by Frank Heckenbach.
12761 2004-12-22 Akim Demaille <akim@epita.fr>
12763 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
12764 (parser::state_type, parser::semantic_type, parser::location_type):
12765 Private, not public.
12766 (parser::parse): Return ints, not bool.
12767 Returning a bool introduces a problem: 0 corresponds to false, and
12768 it seems weird to return false on success. Returning true changes
12769 the conventions for yyparse.
12770 Alternatively we could return void and send an exception.
12771 There is no clear consensus (yet?).
12772 (state_stack, semantic_stack, location_stack): Rename as...
12773 (state_stack_type, semantic_stack_type, location_stack_type): these.
12774 Private, not public.
12775 * tests/c++.at: New.
12776 * tests/testsuite.at, tests/Makefile.am: Adjust.

12780 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
12782 2004-12-21 Akim Demaille <akim@epita.fr>
12784 Don't impose std::string for filenames.
12786 * data/lalr1.cc (b4_filename_type): New.
12787 (position::filename): Use it.
12788 (parser.hh): Move the inclusion of stack.hh and location.hh below
12789 the user code, so that needed headers for the filename type can be
12791 Forward declare them before the user code.
12792 * tests/Makefile.am (check-local, installcheck-local): Pass
12793 TESTSUITEFLAGS to the TESTSUITE.
12795 2004-12-20 Akim Demaille <akim@epita.fr>
12797 Use more STL like names: my_class instead of MyClass.

12804 (semantic_type, state_stack, state_type, token_number_type, stack)
12805 (slice, traits, parser::yylloc, parser::yylval): these.
12807 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.

12811 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
12812 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
12814 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
12816 Remove uses of 'short int' and 'unsigned short int'. This raises
12817 some arbitrary limits. It uses more memory but nowadays that's
12818 not much of an issue.
12820 This change does not affect the generated parsers; that's a different
12821 task, as some users will want to conserve memory there.
12823 Ideally we should use size_t to represent all object counts, and
12824 something like ptrdiff_t to represent signed differences of object
12825 counts; but that will require more code-cleanup than I have the
12826 time to do right now.
12828 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
12829 Use size_t, not int or short int, to count objects.

12849 2004-12-17 Akim Demaille <akim@epita.fr>
12851 * data/lalr1.cc: Extensive Doxygenation.
12852 (error_): Rename as...
12853 (error): this, since it is visible to the user.
12855 (Parser::message): Now an automatic variable from...
12856 (Parser::yyreport_syntax_error_): here.
12857 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to

12864 Parenthesize rhs to avoid obscure problems with mistakes like
12865 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
12866 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
12867 b4_rhs_location): Likewise.

12869 b4_rhs_location): Likewise.
12871 2004-12-16 Akim Demaille <akim@epita.fr>
12873 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
12874 yacc.c: be sure to stay within yycheck_.
12875 * tests/actions.at: Re-enable C++ tests.
12877 2004-12-16 Akim Demaille <akim@epita.fr>
12879 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
12882 2004-12-16 Akim Demaille <akim@epita.fr>
12884 Use #define to handle the %name-prefix.
12886 * data/glr.c, data/yacc.c: Comment changes.
12887 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
12888 so that one can refer to yylex in the parser file, and have it
12889 renamed, as is the case with other skeletons.
12891 2004-12-16 Akim Demaille <akim@epita.fr>

12915 Fix some problems reported by twlevo at xs4all.
12916 * src/symtab.c (symbol_new): Report an error if the input grammar
12917 contains too many symbols. This is better than calling abort() later.
12918 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
12919 (struct node, struct graph):
12920 Rename member expand to stretch. All uses changed.

12933 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)

12944 2004-12-15 Akim Demaille <akim@epita.fr>
12946 Simplify the C++ parser constructor.
12948 * data/lalr1.cc (debug_): Rename as...
12949 (yydebug_): so that the parser's internals are always in the yy*
12952 (b4_parse_param_decl): Remove the leading comma as it is now only
12953 called as unique argument list.
12954 (Parser::Parser): Remove the constructor accepting a location and
12955 an initial debugging level.
12956 Remove from the other ctor the argument for the debugging level.
12957 (debug_level_type, debug_level, set_debug_level): New.
12959 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
12962 2004-12-15 Akim Demaille <akim@epita.fr>
12964 Remove b4_root related material: failure experiment
12965 (which goal was to allow to derive from a class).
12967 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
12968 definitions and uses.
12970 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
12972 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
12973 not 2, since it's not portable to subtract 1 from the start of an
12974 array. The new item 0 is never set or used. All uses changed.
12976 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
12977 the default definition of YYLLOC_DEFAULT. Problem reported
12978 by Frank Heckenbach.
12980 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
12982 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
12983 the normal case and one for the error case. Just use the
12984 first one uniformly. Problem reported by Frank Heckenbach.
12985 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
12986 use exactly the same macro in both places.
12987 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
12988 so that the normal-case YYRHSLOC works for the error case too.
12990 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
12991 (YYLLOC_DEFAULT): Use the same macro as glr.c.
12992 * doc/bison.texinfo (Location Default Action): Don't claim that
12993 we have an array of locations. Use the same macro for both glr
12994 and lalr parsers. Mention YYRHSLOC. Mention what happens when
12997 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>

13010 * src/relation.h (relation_print, relation_digraph):
13011 Relation sizes are of type relation_node, not size_t (this is
13012 merely a doc fix, since the two types are equivalent).
13013 (relation_transpose): Relation sizes are of type relation_node,
13015 * src/relation.c: Likewise.
13016 (top, infinity): Now of type relation_node, not int.
13017 (traverse, relation_transpose): Use relation_node, not int.
13019 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
13020 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
13021 (yyparse): Remove unused local introduced in 2004-10-25 patch.
13023 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
13024 specifying whether the test should be skipped. Use it tp
13025 specify that the [%defines %skeleton "lalr1.cc"] tests currently
13026 fail on some hosts, and should be skipped.
13028 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
13030 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
13031 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
13032 unless otherwise specified below.
13034 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
13035 to allocate kernel_base, kernel_items, kernel_size, since
13036 they needn't be initialized to 0.
13037 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
13038 * src/closure.c (new_closure): Likewise, for itemset.

13054 (goto_actions): Likewise for state_count.
13055 (pack_table): Likewise for base, pos, check.
13056 (tables_generate): Likewise for width.
13058 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
13059 for initial core. Just have a separate core, so we needn't worry
13060 about whether kernel_size and kernel_base are initialized.
13062 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
13063 kernel_size, kernel_items): Remove unnecessary initialization.

13068 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
13069 conflrow, conflict_table, conflict_list, table, check):
13072 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
13073 This is because all callers pass unsigned int.
13074 * src/closure.h (new_closure): Likewise.
13076 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
13077 (build_relations): Initialize includes[i] in all cases.
13078 * src/reader.c (packgram): Always initialize rules[ruleno].prec
13079 and rules[ruleno].precsym. Initialize members in order.
13080 * src/relation.c (relation_transpose): Always initialize new_R[i]
13082 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
13084 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
13085 conflict_list[0] was always 0, but now it isn't initialized.
13087 * src/table.c (table_grow): When conflict_table grew, the grown
13088 area wasn't cleared. Fix this.
13090 * lib/.cvsignore: Add strdup.c, strdup.h.
13091 * m4/.cvsignore: Add strdup.m4.
13093 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
13095 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
13096 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
13097 GOTO_NUMBER_MAXIMUM, since we occasionally compute
13098 ngotos + 1 without checking for overflow.
13099 (build_relations): Use END_NODE, not -1, to denote end of edges.
13100 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
13101 build_relations): Use goto_number, not int, for goto numbers.
13102 * src/tables.c (save_column, default_goto): Likewise.
13104 2004-11-23 Akim Demaille <akim@epita.fr>
13106 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
13107 of #defining from yystype.
13108 Don't typedef yystype, C++ does not need it.
13109 This lets it possible to forward declare it as union.
13111 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
13113 * bootstrap (gnulib_modules): Add extensions.
13114 Problem reported by Jim Meyering.

13119 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
13120 src/system.h, src/tables.c: XFREE -> free, to accommodate
13121 recent change to gnulib xalloc.h.
13122 Problem reported by Jim Meyering.
13124 2004-11-17 Akim Demaille <akim@epita.fr>

13128 2004-11-17 Akim Demaille <akim@epita.fr>,
13129 Alexandre Duret-Lutz <adl@gnu.org>
13131 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow

13150 * data/glr.c (yyloc_default): Remove; not used.
13151 Problem reported by Frank Heckenbach.
13153 2004-10-25 Akim Demaille <akim@epita.fr>
13155 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
13156 Introduce another definition to address simple location arrays.
13157 (yyGLRStack): New member: yyerror_range.
13158 (yyrecoverSyntaxError, yyparse): Update it.
13159 (yyrecoverSyntaxError): Use it when shifting the error token to
13160 have an accurate range, equivalent to the one computed by both
13161 yacc.c and lalr1.cc.
13162 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
13163 that column numbers start at column 0, as per GNU Coding
13164 Standards, the others tests, and the doc.
13165 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
13166 Adjust to the above change (first column is 0).
13167 And adjust the location of the "<error>", now covering the whole
13170 2004-10-22 Akim Demaille <akim@epita.fr>
13171 and Paul Eggert <eggert@cs.ucla.edu>
13173 Remove some arbitrary limits on goto numbers and relations.
13174 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
13175 initial values, since they're never used.
13176 (set_goto_map): ngotos is now unsigned, so test for overflow
13177 by seeing whether it wraps around to zero.
13178 * src/lalr.h (goto_number): Now size_t, not short int.
13179 (GOTO_NUMBER_MAXIMUM): Remove.
13180 * src/relation.c (relation_print, traverse, relation_transpose):
13181 Check for END_NODE rather than looking at sign.
13182 * src/relation.h (END_NODE): New macro.
13183 (relation_node): Now size_t, not short int.
13185 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
13187 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
13188 keyword, not an identifier. Problem reported by Baron Schwartz in
13189 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
13191 2004-10-11 Akim Demaille <akim@epita.fr>
13193 * src/symtab.c (symbol_check_alias_consistency): Also check
13194 type names, destructors, and printers.
13195 Reported by Alexandre Duret-Lutz.
13196 Recode the handling of associativity and precedence in terms
13197 of symbol_precedence_set.
13198 Accept no redeclaration at all, not even equal to the previous
13200 (redeclaration): New.
13201 Use it to factor redeclaration complaints.
13202 (symbol_make_alias): Don't set the type of the alias, let
13203 symbol_check_alias_consistency do it as for other features.
13204 * src/symtab.h (symbol): Add new member prec_location, and
13206 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
13207 * tests/input.at (Incompatible Aliases): New.
13209 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
13211 .cvsignore fixes to accommodate gnulib changes,
13212 and the practice of naming build directories "_build".
13213 * .cvsignore: Add "_*". Sort.
13214 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
13215 * m4/.cvsignore: Add "*_gl.m4".
13217 2004-10-06 Akim Demaille <akim@epita.fr>
13219 * src/parse-gram.y (add_param): Fix the truncation of trailing
13222 2004-10-05 Akim Demaille <akim@epita.fr>
13224 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
13225 whether the reducion was empty or not. This leaves room to
13226 improve the use of YYLLOC_DEFAULT in such a case.
13227 lalr1.cc is still experimental, so changing this is acceptable.
13228 And finally, there are probably not many users who changed the
13229 handling of locations in GLR, so changing is admissible too.
13231 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
13232 empty reduction, set @$ to an empty location ending the previously
13234 Adjust uses to make sure the code is triggered on empty
13236 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
13237 expected output: empty reductions have empty locations.
13239 2004-09-29 Akim Demaille <akim@epita.fr>
13241 * data/lalr1.cc: Move towards a more standard C++ coding style
13242 for templates: Class < T > -> Class<T>.
13244 2004-09-29 Akim Demaille <akim@epita.fr>
13246 * data/lalr1.cc: Reinstall the former ctor, for sake of
13247 compatibility, but warn it will be removed.
13248 Move towards a more standard C++ coding style (i.e., type *var ->
13251 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
13253 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
13254 since it's less likely to work if NULs are involved in the future.
13256 2004-09-27 Akim Demaille <akim@epita.fr>
13258 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
13260 2004-09-27 Akim Demaille <akim@epita.fr>
13262 * data/lalr1.cc (b4_parse_param_decl_1): New.
13263 (b4_parse_param_decl): Use it to have different names between attribute
13264 and argument names.
13265 (b4_cc_constructor_call): Likewise.
13267 2004-09-24 Akim Demaille <akim@epita.fr>
13269 * src/parse-gram.y (add_param): Strip the leading and trailing
13270 blanks from a formal argument declaration.
13271 (YY_LOCATION_PRINT): New.
13273 2004-09-24 Akim Demaille <akim@epita.fr>
13275 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
13276 after the location.
13278 2004-09-24 Akim Demaille <akim@epita.fr>
13280 * doc/bison.texinfo (Table of Symbols): Sort.
13282 2004-09-21 Akim Demaille <akim@epita.fr>
13284 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
13285 the useless parentheses.
13286 Suggested by Paul Eggert.
13288 2004-09-20 Akim Demaille <akim@epita.fr>
13290 Let the initial-action act on the look-ahead, and use it for the
13291 "initial push" (corresponding to an hypothetical beginning-of-file).
13292 And let lalr1.cc honor %initial-action.
13294 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
13296 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
13297 (Parser::Parser): Remove the ctor that used to initialize it.
13298 (Parser::parse): Like in the other skeletons, issue the "starting
13299 parse" message before any action.
13300 Honor %initial-action.
13301 Initialize the stacks with the lookahead.
13302 * data/yacc.c: Let $$ and @$ in %initial-action designate the
13304 Push them in the stacks.
13305 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
13307 2004-09-20 Akim Demaille <akim@epita.fr>
13309 * doc/bison.texinfo (Initial Action Decl): New.
13311 2004-09-20 Akim Demaille <akim@epita.fr>
13313 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
13314 clearer criterion to define it.
13315 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
13316 When reducing on an empty RHS, use the latest stacked location as
13318 yylloc is not always available.
13319 * data/glr.c: Likewise.
13320 Also, honor initial-actions.
13322 2004-09-20 Akim Demaille <akim@epita.fr>
13324 * data/yacc.c (YY_LOCATION_PRINT): New.
13325 Define when we know YYLTYPE's structure, i.e., when the default
13326 YYLLOC_DEFAULT is used.
13327 * data/c.m4 (b4_yysymprint_generate): Use it.
13328 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
13329 value of the result.
13330 (error_start_): Replace with...
13331 (error_range_): this location array.
13332 This allows to replace code relying on the implementation of
13333 locations by portable code.
13334 * data/yacc.c (yylerrsp): Replace with...
13335 (yyerror_range): this.
13336 Every time a token is popped, update yyerror_range[0], to have an
13337 accurate location for the error token.
13338 * data/glr.c (YY_LOCATION_PRINT): New.
13339 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
13340 deference a pointer.
13341 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
13342 report the location in %printers.
13344 * src/scan-skel.l: Instead of abort, report error messages to ease
13345 understanding skeleton scanning failures.
13347 2004-09-16 Akim Demaille <akim@epita.fr>
13349 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
13350 (iterator, const_iterator): these, to be more in the C++ spirit.
13351 Also, return reverse iterators so that when displaying the stack
13352 we display its bottom first.
13353 (Parser::stack_print_, Parser::reduce_print_): Match the messages
13355 We should probably use vector here though.
13357 2004-09-16 Akim Demaille <akim@epita.fr>
13359 Have more complete shift traces.
13361 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
13362 to report Shifts instead of ad hoc YYDPRINTF invocations,
13363 including for the error token.
13364 * data/lalr1.cc (symprint_): Output the location.
13365 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
13366 output the location within the %printer.
13367 Activate GLR tests, at least to make sure they compile properly.
13368 They still don't pass though.
13369 * tests/calc.at: Adjust expect verbose output, since now "Entering
13370 state..." is on a different line than the "Shifting" message.
13372 2004-09-08 Akim Demaille <akim@epita.fr>
13374 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
13375 Bison directive from the Bison file to the invocation of this
13376 macro, so that these directives are passed to
13377 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
13378 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
13379 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
13380 the extra Bison directives instead of the whole series.
13381 Change the grammar so that there are recoverable errors, and
13382 unrecoverable errors. Now we can have the parser give up before
13383 consuming the whole input. As a result we now can observe that
13384 the lookahead is freed when needed.
13385 Change the parser source to parse argv[1] instead of a hard coded
13387 Simplify yylex, and give a value and location to EOF.
13388 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
13389 passed directives already coded in the file.
13390 Add some tests to check the location of "error".
13391 For some tests, the C++ parser is correct, and not yacc.c.
13392 For other tests, they provide different, but unsatisfying, values,
13393 so keep the C++ value so that at least one parser is "correct"
13394 according to the test suite.
13395 (Actions after errors): Remove, this is subsumed by the
13396 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
13398 2004-09-06 Akim Demaille <akim@epita.fr>
13400 * data/lalr1.cc: Adjust the indentation of the labels.
13401 (Parser::pop): New.
13404 2004-09-06 Akim Demaille <akim@epita.fr>
13406 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
13407 argument, an informative message.
13408 Call YY_SYMBOL_PRINT.
13409 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
13410 * data/lalr1.cc (destruct_): Likewise.
13411 In addition, no longer depend on b4_yysymprint_generate and
13412 b4_yydestruct_generate to generate these functions, do it "by
13415 2004-09-03 Akim Demaille <akim@epita.fr>
13417 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
13418 invoked, yydestruct the lookahead.
13419 * tests/calc.at (Calculator $1): Update the expected lengths of
13420 traces: there is an added line for the discarded lookahead.
13421 * doc/bison.texinfo (Destructor Decl): Some rewording.
13422 Define "discarded" symbols.
13424 2004-09-02 Akim Demaille <akim@epita.fr>
13426 * data/lalr1.cc (translate_, destruct_): No reason to be static.
13428 2004-09-02 Akim Demaille <akim@epita.fr>
13430 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
13431 (YYDSYMPRINTF): Rename as...
13432 (YY_SYMBOL_PRINT): this.
13433 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
13435 Use it instead of direct symprint_ calls.
13436 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
13439 2004-09-02 Akim Demaille <akim@epita.fr>
13441 * data/lalr1.cc (b4_yysymprint_generate): New.
13442 (symprint_): New member function, defined when YYDEBUG.
13443 Use it consistently instead of token/nterm debugging output by
13445 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
13446 %printer calls to use cdebug_ when using lalr1.cc.
13448 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
13450 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
13451 with #ifdef YYDEBUG.
13453 2004-08-26 Akim Demaille <akim@epita.fr>
13455 * doc/bison.texinfo (Implementing Loops): Rename as...
13456 (Implementing Gotos/Loops): this.
13458 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
13460 Adjust to latest gnulib.
13461 * bootstrap (gnulib_modules): Add xalloc-die.
13462 Set LC_ALL=C so that file names sort consistently.
13463 Prefer the gnulib copies of gettext.m4, glibc21.m4,
13464 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
13465 uintmax_t.m4, ulonglong.m4.
13466 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
13467 po.m4 since we are now using _gl.m4 instead.
13469 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
13471 * src/scan-action.l: Remove. Scanning of semantic actions is
13472 handled in scan-gram.l.
13474 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
13476 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
13478 * src/location.h (struct): The file member is a uniqstr.
13479 (equal_boundaries): Use UNIQSTR_EQ for comparison.
13481 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
13483 Fix bug with non-%union parsers that have printers or destructors,
13484 which led to a Bison core dump. Reported by Peter Fales in
13485 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
13487 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
13488 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
13489 not to our own type.
13490 * src/output.c (symbol_destructors_output, symbol_printers_output):
13491 Don't assume %union.
13492 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
13493 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
13494 UNION-FLAG. All callers changed.
13495 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
13496 Use type char, not unsigned int, when declaring an array of char;
13497 this lets us remove a cast.
13498 (Printers and Destructors): Add non-%union test cases.
13500 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
13502 * doc/bison.texinfo: Minor editorial changes, mostly to the new
13503 GLR writeups. E.g., avoid frenchspacing and the future tense,
13504 change "lookahead" to "look-ahead", and change "wrt" to "with
13507 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
13509 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
13510 New sections, split off from the GLR Parsers section. Put the new
13511 Simple GLR Parser near the start of the GLR section, for clarity.
13512 Rewrite connective text.
13514 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
13516 * doc/bison.texinfo (Simple GLR Parsers): New section.
13518 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
13520 * NEWS, TODO, doc/bison.texinfo:
13521 Use "look-ahead" instead of "lookahead", to be consistent.
13522 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
13523 while we're fixing "look-ahead".
13524 * src/conflicts.c (shift_set): Renamed from shiftset.
13525 (look_ahead_set): Renamed from lookaheadset.
13526 * src/print.c: Likewise.

13552 * tests/atlocal.in (CXXFLAGS): Use it.
13554 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
13556 Fix some "make check" problems with C++ reported by

13570 C++ compiler. (trivial change)
13572 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
13574 Spent a few hours checking out which prerequisite versions the
13575 current sources actually require. I went all the way back to
13576 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
13577 a seemingly endless set of combinations of versions more recent
13578 than that. The bottom line is that the current sources require
13579 fairly recent versions of the build tools, and it'll be some work
13581 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
13582 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
13583 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
13584 Add comments explaining why those particular versions are
13587 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
13588 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
13589 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
13591 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
13592 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
13594 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13596 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
13597 0.11.5. Suggested by Bruno Haible.
13598 * bootstrap: Remove gettext version checking.
13600 * doc/bison.texinfo (Decl Summary): Also mention that %union
13601 can depend on prerequisite types. Problem reported by Tim
13604 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13606 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
13607 * README-alpha: Don't tell people not to package this.
13609 * bootstrap: Don't assume $(...) works; use `...` instead.
13610 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
13613 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
13614 put into the -d output file, and mention what to do if YYSTYPE is
13615 defined as a macro.
13617 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13619 Undo change made earlier today: it caused autopoint to not bring
13620 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
13623 * bootstrap: Check that gettext version matches what's in
13624 configure.ac. Warn users to ignore robots.txt ERROR 404.
13625 * bootstrap: Undo today's earlier change (logged below).
13626 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
13628 The gettext version checking is causing more trouble than it's
13629 curing; remove it. Problem reported by Paul Hilfinger.
13631 * bootstrap: Issue a warning that one can expect a message
13632 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
13633 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
13635 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
13637 Ensure that the C++ compiler used for testing actually works on a
13638 simple test program; if not, skip the C++-related tests. Problem
13639 reported by Vin Shelton in:
13640 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
13642 * m4/cxx.m4: New file.

13647 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
13649 * data/glr.c (yylloc): Output this macro even if locations are not
13650 being generated, as the GLR parser needs it even in that case.
13651 Problem reported by Troy A. Johnson
13652 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
13654 * configure.ac (AC_INIT): Update to 1.875e.
13656 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
13658 * NEWS: Version 1.875d.
13659 * configure.ac (AC_INIT): Likewise.
13660 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
13662 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
13663 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
13664 lalr1.cc runs afoul of the first, and the last two are no longer
13665 supported by GCC 3.4.0.
13666 * README: Mention GNU m4 1.4 or later; mention m4 patches.
13667 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
13669 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
13671 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

13683 character and string literals.
13684 (unexpected_end): New function.
13685 (unexpected_eof): Use it.

13708 gets copied to the output file.
13710 2004-04-28 Paul Eggert <eggert@twinsun.com>
13712 Get files from the gnulib and po repositories, instead of relying
13713 on them being in our CVS. Upgrade to latest versions of gnulib
13716 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
13717 * bootstrap: Bootstrap from gnulib and po repositories.
13718 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
13719 * README-cvs: Document these changes. Remove version numbers from

13728 ancient OS, as it gets in the way of latest Autoconf & gnulib.
13729 (AC_HEADER_STDC): Remove: we now assume C89 or better.
13730 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
13731 Do not check for C89 headers, except for locale.h which is used
13732 by the Yacc library and must port to K&R hosts.

13740 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
13741 AM_GNU_GETTEXT): Remove; now done by:
13742 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.

13746 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
13747 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
13748 Define to empty, as gnulib.mk will do the rest for us.

13757 (REALLOC): Use xnrealloc, for likewise.
13758 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
13759 (strnlen, memrchr): Remove decls; functions no longer used.
13760 Include <stpcpy.h>.

13782 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
13783 Remove, as these files are now generated automatically
13784 by bootstrap or automake.
13786 * po/ChangeLog: Remove: all but one entry was a duplicate
13787 of this file, and I moved that 2000-11-02 entry here.

13810 support it. (The latest stable gzip doesn't.)
13812 2004-04-27 Paul Eggert <eggert@twinsun.com>
13814 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
13815 case, as stos_ is now used by destructors due to the 2004-02-09

13830 unconditionally. Do not declare perror.
13831 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
13834 * src/complain.c (_): Remove useless defn, as system.h defines this.
13836 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
13837 with latest obstack.h.

13846 test whether it can stand alone.
13848 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
13849 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
13850 unused declaration.
13852 * tests/synclines.at (%union synch line): Put a dummy member in
13853 the union, because empty unions aren't allowed in C. Caught
13856 2004-04-13 Jim Meyering <jim@meyering.net>
13858 * src/conflicts.c (conflicts_print): Correct format string typo:

13967 $(top_srcdir)/lib and ../lib. This fixes a bug reported
13968 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
13969 There's no need to mention top_builddir since Automake does that
13971 (INCLUDES): Remove, as Automake says it's obsolescent.
13972 Contents migrated into AM_CPPFLAGS as described above.
13973 * lib/Makefile.am (INCLUDES): Remove; obsolescent.

13988 * config/depcomp, config/install-sh: Sync with Automake 1.8.
13989 * src/output.c (output_skeleton): Rename local var.
13990 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
13991 Bison tokens, as this runs afoul of the 2003-10-07 change that
13992 disallowed NUL bytes in character constants or string literals.
13994 * tests/local.at: Require Autoconf 2.59's Autotest.
13995 * tests/testsuite.at: Don't include local.at, since we now assume
13996 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
13998 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
13999 multiple inclusion warnings.

14014 if testsuite doesn't exist.
14016 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
14017 literals, unfortunately.
14018 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
14019 Complain about NUL bytes in character constants or string literals.
14021 2003-10-05 Paul Eggert <eggert@twinsun.com>
14023 * NEWS: Don't document %no-default-prec, as it's still
14025 * doc/bison.texinfo: Document %no-default-prec only if
14026 the defaultprec flag is set. Normally it's not.
14028 2003-10-04 Paul Eggert <eggert@twinsun.com>
14030 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
14031 non-modifiable lvalue, instead of a modifiable one.
14032 * doc/bison.texinfo (Actions): Document that $$ can
14033 be assigned to. Do not claim that $$ and $N are

14091 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
14092 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
14094 2003-08-25 Akim Demaille <akim@epita.fr>
14096 When reducing initial empty rules, Bison parser read an initial
14097 location that is not defined. This results in garbage, and that
14098 affects Bison's own parser. Therefore we need (i) to extend Bison
14099 to support a means to initialize this location, and (ii) to use
14100 this CVS Bison to fix CVS Bison's parser.
14102 * src/reader.h, reader.c (epilogue_augment): Remove, replace
14104 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
14105 * src/parse-gram.y: Adjust.
14106 (%initial-action): New.
14107 (%error-verbose): Since we require CVS Bison, there is no reason
14109 * src/scan-gram.l: Adjust.
14110 * src/Makefile.am (YACC): New, to make sure we use our own parser.
14111 * data/yacc.c (yyparse): Use b4_initial_action.
14113 2003-08-25 Akim Demaille <akim@epita.fr>
14115 * doc/bison.texinfo: Don't promote stdout for error messages.
14117 2003-08-25 Akim Demaille <akim@epita.fr>
14119 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
14120 From Alexandre Duret-Lutz.

14126 2003-08-25 Akim Demaille <akim@epita.fr>
14128 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
14131 2003-08-25 Akim Demaille <akim@epita.fr>
14133 * data/lalr1.cc (Parser::reduce_print_): New.
14136 2003-08-25 Akim Demaille <akim@epita.fr>
14138 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
14139 error recovery loops. This patch is based on
14140 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
14141 Also, augment the similarity between lalr1.cc and yacc.c.
14142 Note: the locations of error recovery rules are not correct yet.
14144 * data/lalr1.cc: Comment changes to augment the similarity between
14145 lalr1.cc and yacc.c.
14146 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
14147 (yyerrlab1): Remove, but where it used to be (now the bottom part of
14148 yyerrlab), when hitting EOF, pop the whole stack here instead of
14149 merely falling thru the default error handling mechanism.
14150 (yyerrorlab): New label, with the old contents of YYERROR,
14151 plus the following change: pop the stack of rhs corresponding
14152 to the production that invoked YYERROR. That is how Yacc
14153 behaves (required by POSIX).
14154 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
14157 2003-08-25 Akim Demaille <akim@epita.fr>
14159 Tune local.at so that people can "autom4te -l autotest calc.at -o
14160 calc" for instance, to extract a sub test suite.
14162 * tests/testsuite.at: Move the initialization, Autotest version
14163 requirement, and AT_TESTED invocation into...
14164 * tests/local.at: here.
14165 * tests/testsuite.at: Include it for compatibility with Autoconf
14167 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
14170 2003-08-04 Paul Eggert <eggert@twinsun.com>
14172 Rework code slightly to avoid gcc -Wtraditional warnings.
14173 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
14174 The returned value is now stored in *YY0. All callers changed.
14175 * src/output.c (merge_output): Adjust to the above change.
14177 2003-07-26 Paul Eggert <eggert@twinsun.com>
14179 * data/glr.c (YYASSERT): New macro.
14180 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
14181 yyresolveStates, yyprocessOneStack):
14182 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
14183 Derived from a suggestion by Frank Heckenbach.
14185 2003-07-25 Paul Eggert <eggert@twinsun.com>
14187 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
14188 for portability to K&R C (after ansi2knr, presumably). See
14189 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
14190 by Frank Heckenbach, though I have omitted the structure-initialization
14191 part of his glr-knr.diff patch since I recall that the Portable
14192 C Compiler didn't require that change.
14194 Let the user specify how to allocate and free memory.
14195 Derived from a suggestion by Frank Heckenbach in
14196 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
14197 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
14198 All uses of free, malloc, realloc changed to use these macros,
14199 and unnecessary casts removed.
14200 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
14202 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
14204 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
14205 use s.empty() rather than s == "" to test for empty string; see
14206 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
14209 2003-06-25 Akim Demaille <akim@epita.fr>
14211 * config/depcomp, config/install-sh: Update from masters.
14213 2003-06-20 Paul Eggert <eggert@twinsun.com>
14215 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
14216 and return properly parenthesized result.
14217 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
14218 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
14219 Remove unnecessary parentheses from uses.
14220 * doc/bison.texinfo (Location Default Action): Describe the
14221 conventions for parentheses.
14223 2003-06-19 Paul Eggert <eggert@twinsun.com>
14225 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
14226 yyreportTree): Do not assume that size_t is the same width as int,
14227 when printing sizes. Print sizes using an unsigned format.
14228 Problem reported by Frank Heckenbach in
14229 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
14231 Port to Forte Developer 7 C compiler.
14232 * data/glr.c (struct YYLTYPE): If locations are not being used,
14233 declare a single dummy member, as empty structs do not conform
14235 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
14236 the Forte Developer 7 C compiler complains that end-of-loop
14237 code is not reached.
14239 2003-06-17 Paul Eggert <eggert@twinsun.com>
14241 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
14242 avoid warnings from picky compilers about redefinition of PARAMS.
14244 2003-06-17 Paul Eggert <eggert@twinsun.com>
14248 * NEWS: Document 1.875b.
14250 * lib/bbitset.h: Do not include config.h; that's the includer's job.
14251 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
14252 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
14253 Don't use 'index' in comments, as it's a builtin fn on some hosts.
14254 * lib/bitset_stats.c: Include gettext.h unconditionally, as
14255 per recent gettext manual's suggestion.
14256 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
14257 Use prototypes, not old-style definitions.
14258 * lib/lbitset.c (lbitset_unused_clear): Likewise.

14273 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
14274 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
14275 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
14276 * lib/vbitset.c, lib/vbitset.h: New files.
14277 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
14278 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
14281 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
14282 `How Can I Reset @code{yyparse}', since texinfo does not allow
14283 arbitrary @ in node names.
14285 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
14286 shouldn't be needed according to the gettext 0.12.1 documentation
14287 but which seem to be needed anyway: codeset.m4 glibc21.m4
14288 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
14289 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
14290 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
14292 * lib/.cvsignore: Add stdbool.h.
14293 * m4/.cvsignore: Add nls.m4, po.m4.
14295 Upgrade to CVS gnulib.
14296 * stdbool_.h: File renamed from stdbool.h.in.
14297 * configure.ac (AM_STDBOOL_H): Invoke this instead of
14299 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
14300 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
14301 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
14302 (MOSTLYCLEANFILES): New var.
14303 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
14304 (stdbool.h): New rule.
14305 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
14306 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
14307 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
14308 m4/quote.m4: Upgrade to today's gnulib.
14310 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
14311 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
14312 the tests right now.
14313 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
14314 yyerror are declared before use; C99 requires this.
14316 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
14318 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
14320 (yyrecoverSyntaxError): Correct the logic for setting and testing
14322 Correct comment on handling EOF.
14323 Allow states with only a default reduction, rather than failing
14324 (I can't quite reconstruct why these were not allowed before).
14326 Fixes to avoid problem that $-N rules in GLR parsers can cause
14327 buffer overruns, corrupting state.
14329 * src/output.c (prepare_rules): Output max_left_semantic_context
14331 * src/reader.h (max_left_semantic_context): New variable declaration.
14332 * src/scan-gram.l (max_left_semantic_context): Define.
14333 (handle_action_dollar): Update max_left_semantic_context.
14334 * data/glr.c (YYMAXLEFT): New definition.
14335 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
14336 (yyresolveAction): Ditto.
14338 Fixes to problems with location handling in GLR parsers reported by
14339 Frank Heckenbach (2003/06/05).
14341 * data/glr.c (YYLTYPE): Make trivial if locations not used.
14342 (YYRHSLOC): Add parentheses, and define only if locations used.
14343 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
14344 locations not used.
14345 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
14346 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
14348 * tests/cxx-type.at: Exercise location information; update tests
14349 to differentiate output with and without locations.
14350 Remove forward declarations of yylex and yyerror---caused errors
14351 because default YYLTYPE not yet defined.
14352 Change semantic actions to compute strings, rather than printing
14353 them directly (to test proper passing of semantics values). Change
14354 output to prefix notation and update test data and expected results.
14355 (yylex): Track locations.
14356 (stmtMerge): Return value rather than printing, and include arguments
14359 2003-06-03 Paul Eggert <eggert@twinsun.com>
14361 Avoid warnings generated by GCC 2.95.4 when Bison is
14362 configured with --enable-gcc-warnings.
14363 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
14364 yy::]b4_parser_class_name[::translate_,
14365 yy::Stack::operator[] (unsigned),
14366 yy::Stack::operator[] (unsigned) const,
14367 yy::Slice::operator[] (unsigned),
14368 yy::Slice::operator[] (unsigned) const):
14369 Rename local vars to avoid warnings.
14370 * tests/glr-regression.at (Improper handling of embedded actions
14371 and $-N in GLR parsers): Remove unused local variable from yylex.
14372 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
14373 (void) as arg when not pure, since we now assume C89 when building
14374 Bison. Pacify GCC by using parameter.
14376 2003-06-02 Paul Eggert <eggert@twinsun.com>
14378 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
14379 yy::Location::lines, yy::Location::columns): Rename arguments
14380 to avoid shadowing; this removes a warning generated by GCC 3.3.
14382 2003-06-01 Paul Eggert <eggert@twinsun.com>
14384 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
14385 to g++, as GCC 3.3 complains if you do it.
14386 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
14387 everything that WARNING_CFLAGS has, except omit warnings
14388 not suitable for C++.
14389 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
14390 * tests/atlocal.in (CXXFLAGS): New var.
14391 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
14393 Fix a GLR parser bug I reported in February; see
14394 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
14395 The problem was that GLR parsers did not conform to the C standard,
14396 because actions like { $1 = $2 + $3; } expanded to expressions
14397 that invoked YYFILL in separate subexpressions, and YYFILL assigned
14398 to a local variable. The C standard says that expressions
14399 like (var = f ()) + (var = f ()) have undefined behavior.
14400 Another problem was that GCC sometimes issues warnings that
14401 yyfill and its parameters are unused.
14403 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
14404 as possibly unused.
14405 (yyfill): New function.
14407 (yyuserAction): Change type of yynormal to bool, so that it matches
14408 the new yyfill signature. Mark it as possibly unused.
14411 Follow up on a bug I reported in February, where a Bison-generated
14412 parser can loop. Provide a test case and a fix for yacc.c. I
14413 don't have a fix for lalr1.cc or for glr.c, unfortunately.
14414 The original bug report is in:
14415 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
14417 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
14418 macro's size was becoming unwieldy.
14419 (yyerrlab): Do not discard an empty lookahead symbol, as this
14420 might destroy garbage.
14421 (yyerrorlab): New label, with the old contents of YYERROR,
14422 plus the following change: pop the stack of rhs corresponding
14423 to the production that invoked YYERROR. That is how Yacc
14424 behaves, and POSIX requires this behavior.
14425 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
14426 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
14427 Define 'alarm' to do nothing if unistd.h is not available.
14428 Add a new rule "exp: '-' error;" to test the above change to
14429 data/yacc.c. Use 'alarm' to abort any test taking longer than
14430 10 seconds, as it's probably looping.
14431 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
14432 Also, the new yacc.c generates two fewer diagnostics for an
14435 2003-05-24 Paul Eggert <eggert@twinsun.com>
14437 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
14438 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
14439 This fixes a problem reported by John Bowman when the Compaq/HP
14440 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
14441 -ansi -Wall -gall).
14442 * data/yacc.c (union yyalloc): Likewise.
14443 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
14445 Switch from 'int' to 'bool' where that makes sense.
14447 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
14448 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

14450 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
14451 Return or accept bool, not int. All callers changed.

14471 lbitset_xor_cmp): Likewise.
14472 * lib/bbitset.h: Include <stdbool.h>.

14474 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
14475 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,

14504 * src/state.c (state_rule_lookaheads_print): Likewise.
14506 * config/install-sh: Sync from automake 1.7.5.
14508 2003-05-14 Paul Eggert <eggert@twinsun.com>
14510 * src/parse-gram.y (rules_or_grammar_declaration): Require a
14511 semicolon after a grammar declaration, in the interest of possible
14512 future changes to the Bison input language.
14513 Do not allow a stray semicolon at the start of the grammar.
14514 (rhses.1): Allow one or more semicolons after any rule, including
14515 just before "|" as required by POSIX.
14516 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
14519 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
14521 %parse-param support for lalr1.cc.
14523 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
14524 b4_cc_constructor_calls, b4_cc_constructor_call,
14525 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
14527 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
14528 parse-param arguments.
14529 (yy::b4_parser_class_name): Declare instance variables to
14530 hold parse-param arguments.
14531 * tests/calc.at: s/value/semantic_value/ because value clashes
14532 with a member of yy::b4_parser_class_name. Adjust C++ code
14533 to handle %parse-param. Enable %parse-param test in C++.
14535 2003-05-12 Paul Eggert <eggert@twinsun.com>
14537 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
14538 English a bit. Fix fclose typo. Change "const char" to "char
14539 const", and use ANSI C rather than K&R for "main". Suggest
14540 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
14541 and suggest yy_switch_to_buffer.
14543 2003-05-05 Paul Eggert <eggert@twinsun.com>
14545 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
14546 C89. This avoids a diagnostic on compilers that define __STDC__
14547 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
14548 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
14550 2003-05-03 Paul Eggert <eggert@twinsun.com>
14552 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
14553 Do not overrun array bounds.
14554 This should fix a bug reported today by Olatunji Oluwabukunmi in
14555 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
14557 2003-04-29 Akim Demaille <akim@epita.fr>
14559 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
14560 * src/getargs.c, src/getargs.h: here, as bool, not int.
14561 (nondeterministic_parser): New.
14562 * src/parse-gram.y, src/scan-gram.l: Support
14563 %nondeterministic-parser.
14564 * src/output.c (prepare): Use nondeterministic_parser instead
14565 of glr_parser where appropriate.
14566 * src/tables.c (conflict_row, action_row, save_row)
14567 (token_actions, token_actions, pack_vector): Ditto.
14569 2003-04-29 Akim Demaille <akim@epita.fr>
14571 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
14573 2003-04-29 Akim Demaille <akim@epita.fr>
14575 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
14576 with %pure-parser and %locations to exercise the patch from Yakov
14579 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
14581 * data/yacc.c: (b4_lex_param): Corrected for the case where
14582 %lex-param is provided and %pure-parser isn't.
14584 2003-04-27 Paul Eggert <eggert@twinsun.com>
14586 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
14587 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
14588 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
14589 if it is not defined.
14590 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
14592 2003-04-26 Paul Eggert <eggert@twinsun.com>
14594 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
14595 Declare to be of type suitable for the ninf value itself, not of
14596 type suitable for the corresponding table, since the latter might
14597 be unsigned but the ninf value might be negative. This fixes a
14598 bug reported by Alexandre Duret-Lutz in
14599 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
14601 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
14602 invokes it. We shouldn't invoke it twice because it will attempt
14603 to put error.o in the archive twice. This fixes a glitch reported
14604 by Martin Mokrejs in
14605 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
14607 2003-04-21 Paul Eggert <eggert@twinsun.com>
14609 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
14612 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
14614 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
14615 Fix obvious typo that results in uncompilable GLR parsers
14616 when both %pure-parser and %locations are used. (trivial change)
14618 2003-04-17 Paul Eggert <eggert@twinsun.com>
14620 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
14621 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
14622 Do not insert the expected token via unput, as this runs afoul
14623 of a POSIX-compatibility bug in flex 2.5.31.
14624 All uses changed to BEGIN the parent state,
14625 since we no longer insert the expected token via unput.
14626 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
14627 that is no longer emitted after the above change.
14629 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
14630 the first one. This change is from Paul Hilfinger, and it fixes
14631 regression reported by Werner Lemberg in
14632 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
14634 (resolve_sr_conflict): Don't invoke state_errs_set
14635 unless one or more tokens have been explicitly made errors.
14636 Otherwise, the above change causes Bison to abort.
14638 * tests/existing.at (GNU pic Grammar): New test case, taken from
14641 2003-03-31 Akim Demaille <akim@epita.fr>
14643 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
14645 2003-03-31 Akim Demaille <akim@epita.fr>
14647 * src/output.c (prepare_symbols): Avoid trailing spaces in the
14650 2003-03-31 Akim Demaille <akim@epita.fr>
14652 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
14653 From Paul Hilfinger.
14655 2003-03-29 Akim Demaille <akim@epita.fr>
14657 * m4/error.m4: Do not put under dynamic conditions some code which
14658 expansion is under static control.
14660 2003-03-29 Akim Demaille <akim@epita.fr>
14662 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
14664 2003-03-29 Akim Demaille <akim@epita.fr>
14666 * doc/bison.texinfo (Strings are Destroyed): New.
14668 2003-03-13 Paul Eggert <eggert@twinsun.com>
14670 * .cvsignore: Add configure.lineno.
14671 * src/.cvsignore: Add yacc.
14672 * tests/.cvsignore: Add testsuite.log.
14673 * doc/fdl.texi: Sync with latest FSF version.
14675 2003-03-12 Paul Eggert <eggert@twinsun.com>
14677 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
14678 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
14679 cursor, instead of leaving it undefined. This fixes a bug
14680 reported by Tim Van Holder in
14681 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
14682 * tests/input.at (Torturing the Scanner): Test the scanner on
14683 an empty input file, which was Tim Van Holder's test case.
14685 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
14686 <sys/resource.h> can be included, include sys/time.h and
14687 sys/times.h first, if available. This works around the SunOS
14688 4.1.4 porting bug reported by Bruce Becker in
14689 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
14691 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
14692 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
14693 AC_HEADER_SYS_WAIT.
14695 Merge changes from gnulib. This was prompted because the CVS
14696 snapshot didn't build on Solaris 7 due to strnlen problems.
14698 These changes need to be merged back into gnulib:
14699 * lib/hash.c: Include <stdbool.h> unconditionally.
14700 * m4/onceonly.m4 (m4_quote): New macro.
14701 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
14702 Quote AC_FOREACH variable-expansions properly.
14703 The 2003-01-03 obstack.h change also needs merging.
14704 {end of changes requiring merging}
14706 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
14707 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
14708 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
14709 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
14710 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
14711 New files, imported from gnulib.
14712 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
14715 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
14716 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
14719 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
14721 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
14722 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
14723 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
14724 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
14725 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
14726 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
14727 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
14728 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
14729 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
14730 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
14731 (jm_PREREQ_ARGMATCH): Remove.
14732 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
14733 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
14735 * src/system.h: Include <stdbool.h> unconditionally.
14737 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
14738 assuming at least C89 in the bitset code for some time now.
14740 2003-03-03 Akim Demaille <akim@epita.fr>
14744 2003-03-02 Akim Demaille <akim@epita.fr>
14746 * doc/bison.texinfo (Table of Symbols): Reactivate the
14747 documentation for %lex-param, and %parse-param.
14749 2003-03-02 Akim Demaille <akim@epita.fr>
14751 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
14752 generate verbose error messages.
14753 Use the number of tokens as an upper bound in yytname, as it
14754 cannot be a non terminal.
14756 2003-03-02 Akim Demaille <akim@epita.fr>
14758 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
14761 2003-03-02 Akim Demaille <akim@epita.fr>
14763 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
14764 Use them to exercise yycheck overrun.
14765 Based on Andrew Suffield's grammar.
14767 2003-03-02 Akim Demaille <akim@epita.fr>
14769 Create tests/local.at for Bison generic testing macros.
14771 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
14772 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
14774 * tests/calc.at (AT_CHECK_CALC): Adjust.
14775 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
14776 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
14777 * tests/local.at: here.
14778 (AT_COMPILE_CXX): Tags the tests using it as c++.
14779 Ignore the test if CXX is not functional.
14781 2003-03-01 Paul Eggert <eggert@twinsun.com>
14783 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
14784 not loc->end, since loc->end might contain garbage and this leads
14785 to undefined behavior on some platforms.
14786 (id_loc, token_start): Use (IF_LINTed) initial values that do not
14787 depend on *loc, so that the reader doesn't give the the false
14788 impression that *loc is initialized.
14789 (<INITIAL>"%%"): Do not bother setting code_start, since its value
14790 does not survive the return.
14792 2003-03-01 Akim Demaille <akim@epita.fr>
14794 * src/scan-gram.l (code_start): Always initialize it when entering
14795 into yylex, as SC_EPILOGUE is activated *before* the corresponding
14796 yylex invocation. An alternative would be making it static, but
14797 then it starts with the second %%'s beginning, instead of its end.
14799 2003-02-28 Paul Eggert <eggert@twinsun.com>
14801 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
14802 around a UnixWare 7.1.1 porting bug reported by John Hughes in
14803 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
14805 2003-02-26 Paul Eggert <eggert@twinsun.com>
14807 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
14808 Remove Sequent/Pyramid discussion (nobody uses them any more).
14809 Merge VMS and MS-DOS discussion; these ports may well be dead
14810 but let's keep mentioning them for now. Put <> around email
14811 addresses. Add copyright notice.
14813 2003-02-24 Paul Eggert <eggert@twinsun.com>
14815 * data/glr.c (yy_reduce_print): yylineno -> yylno,
14816 to avoid collision with flex use of yylineno.
14817 Problem reported by Bruce Lilly in
14818 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
14819 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
14820 * data/yacc.c (yy_reduce_print): Likewise.
14822 * config/depcomp: Sync with Automake 1.7.3.
14824 2003-02-21 Akim Demaille <akim@epita.fr>
14826 * data/lalr1.cc: Use temporary variables instead of casts to
14827 change integer types.
14828 Suggested by Paul Eggert.
14830 2003-02-21 Akim Demaille <akim@epita.fr>
14832 * doc/bison.texinfo: Use "location" consistently to refer to @n,
14833 to avoid confusions with lalr1.cc's notion of Position.
14834 Suggested by Paul Eggert.
14836 2003-02-20 Akim Demaille <akim@epita.fr>
14838 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
14839 before initial_columns.
14840 (location.hh): Use consistent variable names when defining the
14842 Use "last" so that we subtract from Positions, not from unsigned.
14844 2003-02-20 Akim Demaille <akim@epita.fr>
14846 * data/lalr1.cc (position.hh): New subfile, including the extended
14847 and Doxygen'ed documentation of class Position.
14848 (location.hh): Use it.
14849 Document a` la Doxygen.
14850 With the help of Benoit Perrot.
14852 2003-02-20 Akim Demaille <akim@epita.fr>
14854 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
14856 Redefine AT_YYERROR_SEES_LOC_IF using it.
14857 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
14859 Don't use the location in yy::Parser::error_ and
14860 yy::Parser::print_ when not %locations.
14861 Activate more lalr1.cc tests.
14863 2003-02-19 Akim Demaille <akim@epita.fr>
14865 * data/lalr1.cc: When displaying a line number, be sure to make it
14868 2003-02-19 Akim Demaille <akim@epita.fr>
14870 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
14872 (YYABORT, YYACCEPT, YYERROR): New.
14873 * tests/calc.at: Renable the lalr1.cc test.
14875 2003-02-19 Akim Demaille <akim@epita.fr>
14877 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
14878 error recovery, mixing with/without pops and discarding of the
14881 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
14883 2003-02-17 Paul Eggert <eggert@twinsun.com>
14885 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
14886 * tests/testsuite.at (AT_COMPILE): Use them.
14887 This fixes the testsuite problem reported by Robert Lentz in
14888 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
14890 2003-02-12 Paul Eggert <eggert@twinsun.com>
14892 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
14893 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
14894 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
14895 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
14896 Check for malloc failure, for consistency with yacc.c.
14897 (yytname_size): Remove, for consistency with yacc.c.
14899 The bug still remains in data/lalr1.cc, as I didn't have time
14902 2003-02-06 Akim Demaille <akim@epita.fr>
14904 * configure.ac (GXX): Rename as...
14905 (CXX): this, to keep the original Autoconf semantics.
14907 * data/lalr1.cc: Fix b4_copyright invocations.
14908 If YYDEBUG is not defined, don't depend upon name_ being defined.
14909 (location.hh): Include string and iostream.
14910 (Position::filename): New member.
14911 (Position::Position ()): New.
14912 (operator<< (Position)): New.
14913 (operator- (Position, int)): New.
14914 (Location::first, Location::last): Rename as...
14915 (Location::begin, Location::end): these, to mock the conventional
14917 (operator<< (Location)): New.
14918 * tests/atlocal.in (CXX): New.
14919 * tests/testsuite.at (AT_COMPILE_CXX): New.
14920 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
14921 locations in a more synthetic way.
14922 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
14924 Adjust the C locations to match those from Emacs: first column is
14926 Change all the expected results.
14927 Conform to the GCS: simplify the locations when applicable.
14928 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
14929 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
14930 these CPP macros with the m4 macros new defined by...
14931 (AT_CHECK_PUSHDEFS): this, i.e.:
14932 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
14933 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
14935 (AT_CHECK_POPDEFS): Undefine them.
14936 (AT_CHECK_CALC_LALR1_CC): New.
14937 Use it for the first lalr1.cc test.
14939 2003-02-04 Akim Demaille <akim@epita.fr>
14941 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
14942 Location as is defined.
14944 2003-02-04 Akim Demaille <akim@epita.fr>
14946 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
14947 name_ being defined.
14949 2003-02-03 Paul Eggert <eggert@twinsun.com>
14951 * src/gram.h (start_symbol): Remove unused decl.
14953 Use more-consistent naming conventions for local vars.
14955 * src/derives.c (derives_compute): Change type of local var from
14956 int to rule_number.
14957 * src/gram.c (grammar_rules_partial_print): Likewise.
14958 * src/print.c (print_core): Likewise.
14959 * src/reduce.c (reduce_grammar_tables): Likewise.
14961 * src/gram.c (grammar_dump): Change name of item_number *
14962 local var from r to rp.
14963 * src/nullable.c (nullable_compute): Likewise.
14965 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
14967 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
14968 for symbol or symbol_number var.
14969 * src/reader.c (grammar_start_symbol_set): Likewise.
14970 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
14972 * src/state.c (transitions_to): Likewise.
14973 * src/state.h: Likewise.
14974 * src/tables.c (symbol_number_to_vector_number): Likewise.
14976 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
14979 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
14982 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
14985 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
14986 Use str, not s, for char * var. Use ch, not c, for character var.
14987 Use size for size var.
14989 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
14991 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
14993 * src/uniqstr.h: Likewise.
14995 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
14996 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
14997 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
14998 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
14999 param to have same name as that of enum, so that we don't use
15000 "s" to stand for a non-state.
15002 2003-02-02 Akim Demaille <akim@epita.fr>
15004 * src/scan-skel.l: Scan more than one inert character per yylex
15007 2003-02-01 Paul Eggert <eggert@twinsun.com>
15011 * po/LINGUAS: Add ms.
15013 2003-01-30 Akim Demaille <akim@epita.fr>
15015 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
15017 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15019 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
15022 Changes in response to error report by S. Eken: GLR mode does not
15023 handle negative $ indices or $ indices in embedded rules correctly.
15024 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
15026 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
15027 (b4_rhs_location): Ditto.
15028 (yyfill): New function to copy from stack tree into array
15030 (yyuserAction): Modify to allow incremental move of semantic values
15031 to rhs array when in GLR mode.
15032 Define YYFILL to use in user-defined actions to fill semantic array
15034 Remove dummy use of yystack, as there is now a guaranteed use.
15035 (yydoAction): Modify to allow incremental move of semantic values
15036 to rhs array when in GLR mode.
15037 (yyresolveAction): Ditto.
15038 (yyglrShiftDefer): Update comment.
15039 (yyresolveStates): Use X == NULL for pointers, not !X.
15040 (yyglrReduce): Ditto.
15041 (yydoAction): Ditto
15043 * tests/glr-regr1.at: Rename to ...
15044 * tests/glr-regression.at: Add new regression test for the problems
15045 described above (adapted from S. Eken).
15046 Update copyright notice.
15047 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
15048 * tests/Makefile.am: Ditto.
15050 2003-01-28 Paul Eggert <eggert@twinsun.com>
15052 * data/lalr1.cc: Do not use @output_header_name@ unless
15053 b4_defines_flag is set. This fixes two bugs reported by
15055 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
15056 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
15058 2003-01-21 Paul Eggert <eggert@twinsun.com>
15060 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
15061 we don't need to worry about yyerrlab1 being reported as an
15062 "unused label" by non-GCC C compilers. The downside is that if
15063 locations are used then a couple of statements are duplicated each
15064 time YYERROR is invoked, but the upside is that the warnings
15066 (yyerrlab1): Move code to YERROR.
15067 (yyerrlab2): Remove. Change uses back to yyerrlab1.
15068 This reverts some of the 2002-12-27 change.
15070 2003-01-17 Paul Eggert <eggert@twinsun.com>
15072 * src/output.c (symbol_printers_output): Fix typo that led
15073 to core dump. Problem reported by Antonio Rus in
15074 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
15076 2003-01-13 Akim Demaille <akim@epita.fr>,
15077 Quoc Peyrot <chojin@lrde.epita.fr>,
15078 Robert Anisko <anisko_r@lrde.epita.fr>
15080 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
15081 when the stacks contain one element, as the loop would otherwise
15082 free the last state, and then use the top state (the one we just
15083 popped). This means that the initial elements will not be freed
15084 explicitly, as is the case in yacc.c; it is not a problem, as
15085 these elements have fake values.
15087 2003-01-11 Paul Eggert <eggert@twinsun.com>
15089 * NEWS: %expect-violations are now just warnings, reverting
15090 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
15091 bootstrapping problem reported by Matthias Klose; see
15092 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
15093 * src/conflicts.c (conflicts_print): Likewise.
15094 * tests/conflicts.at (%expect not enough, %expect too much,
15095 %expect with reduce conflicts): Likewise.
15096 * doc/bison.texinfo (Expect Decl): Document this. Also mention
15097 that the warning is enabled if the number of conflicts changes
15098 (not necessarily increases).
15100 * src/getargs.c (version): Update copyright year.
15102 2003-01-09 Akim Demaille <akim@epita.fr>
15104 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
15106 2003-01-08 Paul Eggert <eggert@twinsun.com>
15108 * Makefile.maint (WGETFLAGS):
15109 New macro, containing "-C off" to disable proxy caches.
15110 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
15111 (rel-check): Use $(WGET) instead of wget.
15113 2003-01-06 Paul Eggert <eggert@twinsun.com>
15115 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
15116 the GLR paper of Scott, Johnstone and Hussain.
15118 2003-01-04 Paul Eggert <eggert@twinsun.com>
15120 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
15121 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
15122 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
15123 (EXTRA_LIBRARIES): New var, for liby.a.
15124 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
15125 (EXTRA_SCRIPTS): New var, for yacc.
15127 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
15128 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
15129 Problem reported by Nelson H. F. Beebe.
15131 2003-01-03 Paul Eggert <eggert@twinsun.com>
15133 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
15134 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
15135 when compiling Bison 1.875's `bitset bset = obstack_alloc
15136 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
15138 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
15139 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
15140 grow to a huge size with typical invocation.
15142 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
15143 Use the pattern recommended by Autoconf 2.57, except also protect
15144 against double-definition.
15145 * src/system.h: Likewise.
15146 Portability issues reported by Nelson H. F. Beebe.
15148 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
15149 All uses changed. Provide a definition in both C and C++.
15150 (yytrue, yyfalse): Define even if defined (__cplusplus).
15152 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
15153 Reported by Nelson H. F. Beebe.
15155 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
15157 2003-01-02 Paul Eggert <eggert@twinsun.com>
15159 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
15160 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
15161 Bug reported by Nelson H. F. Beebe.
15163 2003-01-01 Paul Eggert <eggert@twinsun.com>
15167 2002-12-30 Paul Eggert <eggert@twinsun.com>
15169 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
15171 (<INITIAL>","): Here. This causes stray "," to be treated
15174 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
15175 last brace in braced code when not in Yacc mode, for compatibility
15176 with Bison 1.35. This resurrects the 2001-12-15 patch to
15179 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
15180 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
15182 2002-12-28 Paul Eggert <eggert@twinsun.com>
15184 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
15185 that of SYM's type. This fixes Debian bug 168069, reported by
15188 2002-12-28 Paul Eggert <eggert@twinsun.com>
15192 Switch back to the Yacc style of conflict reports, undoing some
15193 of the 2002-07-30 change.
15194 * doc/bison.texinfo (Understanding): Use Yacc style for
15195 conflict reports. Also, use new way of locating rules.
15196 * src/conflicts.c (conflict_report):
15197 Renamed from conflict_report_yacc, removing the old
15198 'conflict_report'. Translate the entire conflict report at once,
15199 so that we don't assume that "," has the same interpretation in
15201 (conflicts_output): Use Yacc-style conflict report for each state,
15202 instead of our more-complicated style.
15203 (conflicts_print): Use Yacc-style conflict report, except print
15204 the input file name when not emulating Yacc.
15205 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
15206 Conflicted Reduction, %expect not enough, %expect too much,
15207 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
15208 * tests/existing.at (GNU Cim Grammar): Likewise.
15209 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
15211 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
15212 fatal): Don't invoke fflush; it's not needed and it might even be
15213 harmful for stdout, as stdout might not be open.
15214 * src/reduce.c (reduce_print): Likewise.
15216 2002-12-27 Paul Eggert <eggert@twinsun.com>
15218 Fix a bug where error locations were not being recorded correctly.
15219 This problem was originally reported by Paul Hilfinger in
15220 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
15222 * data/yacc.c (yyparse): New local var yylerrsp, to record the
15223 top of the location stack's error locations.
15224 (yyerrlab): Set it. When discarding a token, push its location
15225 onto yylerrsp so that we don't lose track of the error's end.
15226 (yyerrlab1): Now is only the target of YYERROR, so that we can
15227 properly record the location of the action that failed. For GCC
15228 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
15229 GCC warning about yyerrlab1 being unused if YYERROR is unused.
15230 (yyerrlab2): New label, which yyerrlab now falls through to.
15231 Compute the error's location by applying YYLLOC_DEFAULT to
15232 the locations of all the symbols that went into the error.
15233 * doc/bison.texinfo (Location Default Action): Mention that
15234 YYLLOC_DEFAULT is also invoked for syntax errors.
15235 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
15236 Error locations include the locations of all the tokens that were
15237 discarded, not just the last token.
15239 2002-12-26 Paul Eggert <eggert@twinsun.com>
15241 * src/files.c: Include quote.h.
15242 (compute_output_file_names): Warn if we detect conflicting
15243 outputs to the same file. This should catch the misunderstanding
15244 exemplified by Debian Bug 165349, reported by Bruce Stephens..
15246 * src/conflicts.c (conflicts_print): If the user specifies
15247 "%expect N", report an error if there are any reduce/reduce
15248 conflicts. This is what the manual says should happen.
15249 This fixes Debian bug 130890, reported by Anthony DeRobertis.
15250 * tests/conflicts.at (%expect with reduce conflicts): New test.
15252 Don't use m4_include on relative file names, as it doesn't work as
15253 desired if there happens to be a file with that name under ".".
15255 * m4sugar/version.m4: Remove; it was included but it wasn't used.
15256 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
15257 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
15258 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
15259 * src/output.c (output_skeleton): Use full path names when
15260 specifying a file to include; don't rely on include path, as
15261 it's unreliable when the working file contains a file with
15264 2002-12-25 Paul Eggert <eggert@twinsun.com>
15266 Remove obsolete references to bison.simple and bison.hairy.
15267 Problem mentioned by Aubin Mahe in
15268 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
15269 * data/glr.c: Comment fix.
15270 * doc/bison.1: Remove references. Also, mention "yacc".
15272 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
15275 * src/parse-gram.y (declaration): Use enum "report_states" rather
15276 than its numeric value 1.
15278 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
15279 opening a new one. This fixes Debian bug 165349, reported by
15282 2002-12-24 Paul Eggert <eggert@twinsun.com>
15286 * Makefile.maint (cvs-update): Don't assume that the shell
15287 supports $(...), as Solaris sh doesn't.
15289 * src/parse-gram.y (lloc_default): Remove test for empty
15290 nonterminals at the end, since it didn't change the result.
15292 2002-12-24 Paul Eggert <eggert@twinsun.com>
15294 If the user does not define YYSTYPE as a macro, Bison now declares it
15295 using typedef instead of defining it as a macro. POSIX requires this.
15296 For consistency, YYLTYPE is also declared instead of defined.
15298 %union directives can now have a tag before the `{', e.g., the
15299 directive `%union foo {...}' now generates the C code
15300 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
15301 The default union tag is `YYSTYPE', for compatibility with Solaris 9
15302 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
15303 instead of `yyltype'.
15305 `yystype' and `yyltype' are now obsolescent macros instead of being
15306 typedefs or tags; they are no longer documented and will be
15307 withdrawn in a future release.
15309 * data/glr.c (b4_location_type): Remove.
15310 (YYSTYPE): Renamed from yystype.
15311 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
15312 (struct YYLTYPE): Renamed from struct yyltype.
15313 (YYLTYPE): Renamed from yyltype.
15314 (yyltype, yystype): New (and obsolescent) macros,
15315 for backward compatibility.
15316 * data/yacc.c: Likewise.
15318 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
15319 does not specify a union tag. This is for compatibility with
15322 * src/parse-gram.y (add_param): 2nd arg is now char * not char
15323 const *, since it is now modified by stripping surrounding { }.
15324 (current_braced_code): Remove.
15325 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
15326 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
15327 trailing " {...}". Now of type <chars>.
15328 (grammar_declaration): Adjust to bundled tokens.
15329 (code_content): Remove; stripping is now done by add_param.
15330 (print_token_value): Print contents of bundled tokens.
15331 (token_name): New function.
15333 * src/reader.h (braced_code, current_braced_code): Remove.
15334 (token_name): New decl.
15336 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
15337 token_type, not braced_code code_kind. All uses changed.
15338 (SC_PRE_CODE): New state, for scanning after a keyword that
15339 has (or usually has) an immediately-following braced code.
15340 (token_type): New local var, to keep track of which token type
15341 to return when scanning braced code.
15342 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
15343 <INITIAL>"%parse-param", <INITIAL>"%printer",
15344 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
15345 instead of returning a token type immediately.
15346 (<INITIAL>"{"): Set token type.
15347 (<SC_BRACED_CODE>"}"): Use it.
15348 (handle_action_dollar, handle_action_at): Now returns bool
15349 indicating success. Fail if ! current_rule; this prevents a core dump.
15350 (handle_symbol_code_dollar, handle_symbol_code_at):
15351 Remove; merge body into caller.
15352 (handle_dollar, handle_at): Complain in invalid contexts.
15354 * NEWS, doc/bison.texinfo: Document the above.
15355 * NEWS: Fix years and program names in copyright notice.
15357 2002-12-17 Paul Eggert <eggert@twinsun.com>
15359 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
15360 Reporting, Table of Symbols): Omit mentions of %lex-param and
15361 %parse-param from the documentation for now.
15363 2002-12-15 Paul Eggert <eggert@twinsun.com>
15365 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
15366 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
15367 lookahead symbol, and which sets yychar in parser actions) and it
15368 disagreed with the Bison documentation. Bug
15369 reported by Andrew Walrond.
15371 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
15372 as the caller now does that.
15373 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
15374 (YYEMPTY): Parenthesize right hand side, since others use it.
15375 (yyparse): Don't assume that our generated code is the only code
15378 2002-12-13 Paul Eggert <eggert@twinsun.com>
15382 POSIX requires a "yacc" command.
15383 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
15384 (MOSTLYCLEANFILES): Add yacc.
15386 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
15387 as an alias for bison y.
15389 * po/LINGUAS: Add da.
15391 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
15392 problem with latest <getopt.h>.
15393 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
15395 * doc/fdl.texi: Upgrade to 1.2.
15396 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
15397 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
15398 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
15400 * config/install-sh: Sync with autotools.
15402 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
15403 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
15404 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
15405 locations are requested.
15406 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
15407 locations are requested.
15409 2002-12-12 Paul Eggert <eggert@twinsun.com>
15411 Remove unportable casts and storage allocation tricks.
15412 While we're at it, remove almost all casts, since they
15413 usually aren't needed and are a sign of trouble.
15415 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
15417 * src/derives.c (derives_compute): Do not subtract NTOKENS from
15418 the pointer DSET returned by malloc; this isn't portable.
15419 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
15420 Similarly for DERIVES.
15421 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
15422 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

15425 * src/derives.c (derives_compute): Do not bother invoking
15426 int_of_rule_number, since rule numbers are integers.

15449 * src/muscle_tab.c (muscle_m4_output):
15450 Now inline. Return bool, not int.
15451 * src/state.c (state_compare): Likewise.
15452 * src/symtab.c (symbol_check_defined,
15453 symbol_check_alias_consistency, symbol_pack, symbol_translation,

15464 * src/uniqstr.c (uniqstr_print_processor): Likewise.
15465 * src/muscle_tab.c (muscles_m4_output):
15466 Use new functions instead of casting old functions unportably.
15467 * src/state.c (state_hash_new): Likewise.
15468 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
15469 symbols_token_translations_init):
15471 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
15473 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
15474 var instead of casting to long, to avoid casts.
15475 (prepare_states): Use MALLOC rather than alloca, so that we don't
15476 have to worry about alloca.
15477 * src/state.c (state_hash_lookup): Likewise.
15479 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
15480 local var instead of casting to unsigned char, to avoid casts.
15482 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
15483 STATE_ALLOC): Remove.
15484 (transitions_new, errs_new, reductions_new, state_new): Use malloc

15489 * src/state.c (state_hash): Use unsigned accumulator, not signed.
15491 * src/symtab.c (symbol_free): Remove; unused.

15497 (symbol_processor): Remove.
15498 (symbols_do): Remove decl; now static.
15500 * src/system.h (alloca): Remove; decl no longer needed.
15501 (<stddef.h>): Include, for offsetof.
15502 (<inttypes.>, <stdint.h>): Include if available.
15503 (uintptr_t): New type, if system lacks it.
15504 (CALLOC, MALLOC, REALLOC): New macros.
15505 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
15508 * src/tables.c (table_size): Now int, to pacify GCC.
15509 (table_grow, table_ninf_remap): Use signed table size.

15521 2002-12-09 Paul Eggert <eggert@twinsun.com>
15523 Change identifier spellings to avoid collisions with names
15524 that are reserved by POSIX.
15526 Don't use names ending in _t, since POSIX reserves them.
15527 For consistency, remove _e and _s endings -- they're weren't
15528 needed to remove ambiguity. All uses changed.
15529 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
15530 turn was just renamed from struniq_t.
15531 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
15532 which in turn was just renamed from struniq_processor_t.
15533 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
15534 in turn was renamed from hash_compare_struniq_t.

15604 value_t_as_yystype -> value_as_yystype.
15606 Don't include <errno.h> in the mainstream code, since it
15607 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
15608 * lib/get-errno.c, lib/get-errno.h: New files.
15609 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
15611 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
15612 * src/output.c (output_skeleton): Likewise.

15619 (TAB_EXT): Renamed from EXT_TAB.
15620 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
15622 Avoid str[a-z]*, since <string.h> reserves that name space.
15623 Change all instances of "struniq" in names to "uniqstr", and
15624 likewise for "STRUNIQ" and "UNIQSTR".
15625 * src/uniqstr.c: Renamed from src/struniq.c.
15626 * src/uniqstr.h: Renamed from src/struniq.h.
15627 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

15630 * src/files.h (strsuffix, stringappend): Remove; unused.
15631 * src/parse-gram.y (<chars>): Renamed from <string>.

15637 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
15638 (N_EXPAND): Renamed from N_STRETCH.

15649 (BASE_MINIMUM): Renamed from BASE_MIN.
15650 (ACTION_MAX): Remove; unused.
15651 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
15652 Unnecessary casts removed from above defines.
15655 Fix misspelling in names.
15656 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
15657 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
15661 * lib/timevar.c (timevar_report): Renamed from time_report,
15662 for consistency with other names.
15663 * lib/timevar.h (timevar_report): New decl.
15664 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
15667 Sort include-file uses.
15669 Reorder all include files under src to be in the order "system.h".
15670 then the ../lib include files in angle brackets (alphabetized),
15671 then the . include files in double-quotes (alphabetized). Fix
15672 dependency breakages encountered in this process, as follows:
15673 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
15674 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
15675 * src/state.h: Include "symtab.h".
15677 2002-12-08 Paul Eggert <eggert@twinsun.com>
15679 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
15680 since this causes problems when __file__ contains character
15681 sequences like "@" that are treated specially by src/scan-skel.l.
15682 Instead, just use the file's basename. This fixes the bug
15683 reported by Martin Mokrejs in
15684 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
15686 2002-12-06 Paul Eggert <eggert@twinsun.com>
15688 Add support for rules that do not have trailing semicolons, as
15689 POSIX requires. Improve the quality of locations in Bison
15692 * src/location.c: Include <quotearg.h>.
15693 (empty_location): Now const.
15694 (location_print): New function. Follow the recommendation of the
15695 GNU Coding Standards for locations that span file boundaries.
15696 * src/location.h: Do not include <quotearg.h>; no longer needed.
15697 (boundary): New type.
15698 (location_t): Use it. This allows locations to span file boundaries.
15699 All member uses changed: file -> start.file or end.file (as needed),
15700 first_line -> start.line, first_column -> start.column,
15701 last_line -> end.line, last_column -> end.column.
15702 (equal_boundaries): New function.
15703 (LOCATION_RESET, LOCATION_STEP): Remove.
15704 (LOCATION_PRINT): Remove. All callers changed to use location_print.
15705 (empty_location): Now const.
15706 (location_print): New decl.
15707 * src/parse-gram.y (lloc_default): New function, which handles
15708 empty locations more accurately.
15709 (YYLLOC_DEFAULT): Use it.
15710 (%token COLON): Remove.
15711 (%token ID_COLON): New token.
15713 (declarations, rules): Remove trailing semicolon.
15714 (declaration, rules_or_grammar_declaration):

15717 (rules_or_grammar_declaration): Remove trailing semicolon.
15718 (semi_colon.opt): Remove.
15719 * src/reader.h: Include location.h.
15720 (scanner_cursor): New decl.
15721 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
15723 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
15725 (STEP): Remove. No longer needed, now that adjust_location does
15726 the work. All uses removed.
15727 (scanner_cursor): New var.
15728 (adjust_location): Renamed from extend_location. It now sets
15729 *loc and adjusts the scanner cursor. All uses changed.
15730 Don't bother testing for CR.
15731 (handle_syncline): Remove location arg; now updates scanner cursor.
15732 All callers changed.
15733 (unexpected_end_of_file): Now accepts start boundary of token or
15734 comment, not location. All callers changed. Update scanner cursor,
15736 (SC_AFTER_IDENTIFIER): New state.
15737 (context_state): Renamed from c_context. All uses changed.
15738 (id_loc, code_start, token_start): New local vars.
15739 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
15740 processing of Yacc white space and equivalents here.
15741 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
15742 instead of returning ID immediately, since we need to search for
15743 a subsequent colon.
15744 (<INITIAL>"'", "\""): Save token_start.
15745 (<INITIAL>"%{", "{", "%%"): Save code_start.
15746 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
15747 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
15748 BEGIN context_state at end, not INITIAL.
15749 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
15750 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
15751 Return correct token start.
15752 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
15753 the start of a character, string or multiline comment is found.
15754 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
15755 Reduction): Adjust reported locations to match the more-precise
15756 results now expected.
15757 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
15758 * tests/reduce.at (Useless Rules, Reduced Automaton,
15759 Underivable Rules): Likewise.
15760 * tests/regression.at (Invalid inputs): No longer `expecting ";"
15761 or "|"' now that so many other tokens are allowed by the new grammar.
15763 * src/complain.h (current_file): Remove duplicate decl;
15764 current_file is now owned by files.h.
15765 * src/complain.c, src/scan-gram.l: Include files.h.
15767 2002-12-06 Paul Eggert <eggert@twinsun.com>
15769 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
15770 promotes to int; it might be unsigned int.
15771 * data/yacc.c (yy_reduce_print): Likewise.
15773 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
15774 be #defined in the prologue, not in the Bison declarations.
15775 This fixes Debian Bug 102878, reported by Shaul Karl.
15777 2002-12-02 Paul Eggert <eggert@twinsun.com>
15779 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
15780 * lib/strtoul.c: New file, from gnulib.
15781 This fixes a porting bug reported by Peter Klein in
15782 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
15784 2002-11-30 Paul Eggert <eggert@twinsun.com>
15786 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
15787 and put only a forward declaration in the prologue. This is for
15788 consistency with the other scanner helper functions.
15790 Type clashes now generate warnings, not errors, since it
15791 appears that POSIX may allow some grammars with type clashes.
15792 * src/reader.c (grammar_current_rule_check): Warn about
15793 type clashes instead of complaining.
15794 * tests/input.at (Type Clashes): Expect warnings, not complaints.
15796 Add Yacc library, since POSIX requires it.
15797 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
15798 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
15799 * lib/main.c, lib/yyerror.c: New files.
15801 gram_error can be static; it need not be extern.
15802 * src/reader.h (gram_error): Remove decl.
15803 * src/parse-gram.y (gram_error): Now static. Add static decl.
15804 (print_token_value): Omit parameter names from forward decl,
15807 2002-11-29 Paul Eggert <eggert@twinsun.com>
15809 * doc/bison.texinfo: Emphasize that yylex and yyerror must
15810 be declared before being used. E.g., one should typically
15811 declare them in the prologue. Use GNU coding style in examples.
15812 Put "const" consistently after the type it modifies. Mention
15813 that C99 supports "inline". Mention that yyerror traditionally
15816 %parse-param and %lex-param now take just one argument, the
15817 declaration; the argument name is deduced from the declaration.
15819 * doc/bison.texinfo (Parser Function, Pure Calling, Error
15820 Reporting, Table of Symbols): Document this.
15821 * src/parse-gram.y (add_param): New function.
15823 (declaration): Implement new rule for %parse-param and %lex-param.
15824 * src/scan-gram.l: "," now elicits a warning, rather than being
15825 a token; this is more compatible with byacc.
15826 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
15828 2002-11-27 Paul Eggert <eggert@twinsun.com>
15830 Rename identifiers to avoid real and potential collisions.
15832 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
15833 to avoid collision with lex macro described by Bruce Lilly in
15834 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
15835 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
15836 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
15837 * src/parse-gram.y (print_token_value): Renamed from yyprint.
15839 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
15840 The name "yycontrol" violates the name space rules, and this stuff
15841 wasn't being used anyway.
15842 (input): Remove action; this stuff wasn't being used.
15843 (gram_error): Rename local variable yylloc -> loc.
15844 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
15845 (YY_DECL): Don't use "yy" at start of local variables.
15846 All uses changed, e.g., yylloc -> loc.
15847 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
15848 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.

15855 2002-11-24 Paul Eggert <eggert@twinsun.com>
15859 * tests/actions.at (Actions after errors): Use an output format
15860 more similar to that of the Printers and Destructors test.
15861 Test the position of the ';' token too.
15862 (Printers and Destructors): Likewise.
15863 (Printers and Destructors: %glr-parser): Remove for now, to avoid
15864 unnecessarily alarming people when the test fails.
15866 * data/yacc.c (yyerrlab1): Move this label down, so that the
15867 parser does not discard the lookahead token if the user code
15868 invokes YYERROR. This change is required for POSIX conformance.
15870 * lib/error.c: Sync with gnulib.
15872 2002-11-22 Paul Eggert <eggert@twinsun.com>
15874 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

15880 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
15882 2002-11-20 Paul Eggert <eggert@twinsun.com>
15884 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
15885 should use `if (! x) abort ();' rather than `assert (x);', and
15886 anyway it's one less thing to worry about configuring.
15888 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
15889 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
15890 and replace all instances of assert with abort.
15891 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.

15897 hash_find_entry, hash_rehash, hash_insert): Likewise.
15898 * src/conflicts.c (resolve_sr_conflict): Likewise.

15909 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
15910 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
15911 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
15913 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
15914 (ARGMATCH_CONSTRAINT): New macro.
15915 (ARGMATCH_ASSERT): Use it.

15919 rather than assert.
15920 * src/tables.c (tables_generate): Likewise.
15922 * src/struniq.c (struniq_assert): Now returns void, and aborts
15923 if the assertion is false.
15924 (struniq_assert_p): Remove.
15925 * src/struniq.h: Likewise.
15927 2002-11-18 Paul Eggert <eggert@twinsun.com>
15929 * data/glr.c (yygetLRActions): Replace `yyindex' with
15930 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
15931 This fixes the regression with Sun ONE Studio 7 cc that I reported in
15932 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
15934 2002-11-18 Akim Demaille <akim@epita.fr>
15936 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
15938 From Tim Van Holder.
15940 2002-11-17 Paul Eggert <eggert@twinsun.com>
15942 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
15943 to "SyntaxError" for consistency with my 2002-11-15 change.
15945 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
15946 not define to {}, since this breaks the common use of `YYDPRINTF
15947 ((...));' if a single statement is desired (e.g. before `else').
15948 Work around GCC warnings by surrounding corresponding calls with
15950 (yyhasResolvedValue): Remove unused function.
15951 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
15953 (yyreportSyntaxError): Renamed from yyreportParseError.
15954 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
15956 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
15957 extern when possible. Remove unused initializations.
15959 2002-11-16 Akim Demaille <akim@epita.fr>
15961 Augment the similarity between GLR and LALR traces.
15963 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
15964 (YY_REDUCE_PRINT): New.
15965 (yyparse): Use them.
15966 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
15968 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
15969 state reached after the reduction/recovery, since...
15970 (yyparse, yyprocessOneStack): Report the state we are entering in.
15972 2002-11-16 Akim Demaille <akim@epita.fr>
15974 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
15975 Add support for --trace=skeleton.
15976 * src/scan-skel.l: %option debug.
15977 Scan strings of non-@ or \n instead of character by character.
15978 (scan_skel): Handle trace_skeleton.
15980 (@output_parser_name@, @output_header_name@): ``Restore'' their
15981 support (used to be M4 macros).
15982 * data/yacc.c: Quote larger chunks, a la glr.c.
15983 * data/lalr1.cc: Likewise.
15984 The header guards are no longer available, so use some other
15985 string than `YYLSP_NEEDED'.
15987 2002-11-16 Akim Demaille <akim@epita.fr>
15989 Make the ``Printers and Destructors'' test more verbose, taking
15990 `yacc.c''s behavior as (possibly wrong) reference.
15992 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
15993 instead of fprint on stdout.
15994 Set and report the last_line of the symbols.
15995 Consistently display values and locations.
15997 2002-11-16 Paul Eggert <eggert@twinsun.com>
15999 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
16001 2002-11-15 Paul Eggert <eggert@twinsun.com>
16003 * tests/actions.at (Actions after errors): New test case.
16005 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
16006 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
16007 tests/action.at, tests/calc.at, tests/conflicts.at,
16008 tests/cxx-type.at, tests/regression.at:
16009 "parse error" -> "syntax error" for POSIX compatibility.
16010 "parsing stack overflow..." -> "parser stack overflow" so
16011 that code matches Bison documentation.
16013 2002-11-15 Akim Demaille <akim@epita.fr>
16015 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
16016 take two BRACED_CODE, not two string_content.
16017 Free the scanner's obstack when we are done.
16018 (code_content): New.
16019 * tests/calc.at: Adjust.
16020 * doc/bison.texinfo: Adjust.
16021 Also, make sure to include the `,' for these declarations.
16023 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
16025 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
16026 definition; avoids potential autoreconf problems.
16028 2002-11-15 Akim Demaille <akim@epita.fr>
16030 Always check the value returned by yyparse.
16032 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
16033 returned by yyparse.

16044 2002-11-14 Paul Eggert <eggert@twinsun.com>
16046 * src/output.c (output_skeleton): Call xfopen instead of
16047 duplicating xfopen's body.
16049 Fix bugs reported by Nelson H. F. Beebe in
16050 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
16052 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
16053 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
16054 Group compiler. Instead, use "$CC -E bar.c". Include the .h
16055 file twice in the grammar, as an extra check.
16057 * tests/input.at (Torturing the Scanner): Surround the
16058 backslash-newline tests with "#if 0", to make it less likely that
16059 we'll run into compiler bugs. Bring back solitary \ inside
16060 comment, but add a closing comment to work around HP C bug. Don't
16061 test backslash-newline in C character constant.
16063 2002-11-14 Akim Demaille <akim@epita.fr>
16065 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
16066 status of the compiler.
16067 Calling `exit 1' is no longer needed.
16068 Reported by Nelson H. F. Beebe.
16070 2002-11-14 Akim Demaille <akim@epita.fr>
16072 * tests/atlocal.in (CPPFLAGS): We have config.h.

16076 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
16077 * tests/regression.at, tests/torture.at: Use them for all the
16078 grammars that are to be compiled.
16079 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
16080 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
16081 * doc/bison.texinfo (GLR Parsers): Document `inline'.
16083 2002-11-14 Akim Demaille <akim@epita.fr>
16085 * doc/bison.texinfo: Various formatting changes (alignments in
16086 samples, additional @group/@end group, GCS in samples.
16087 Use @deffn instead of simple @table to define the directives,
16088 macros, variables etc.
16090 2002-11-13 Paul Eggert <eggert@twinsun.com>
16092 Fix some bugs reported by Albert Chin-A-Young in
16093 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
16095 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
16096 -o c"; the HP C compiler chatters during compilation.
16097 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
16098 * tests/headers.at (export YYLTYPE): Likewise.
16100 * tests/input.at (Torturing the Scanner): Remove lines containing
16101 solitary backslashes, as they tickle a bug in the HP C compiler.
16103 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
16104 comments, since they're not portable. Use GNU coding style.
16106 2002-11-13 Akim Demaille <akim@epita.fr>
16108 * data/yacc.c: Leave bigger chunks of quoted text.
16109 (YYDSYMPRINTF): New.
16110 Use it to report symbol activities.

16118 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
16119 (yyglrReduce): Return yyok, not 0.
16120 This should avoid the enumerated-type warnings reported
16121 by Nelson H. F. Beebe in
16122 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
16124 * lib/bbitset.h (BITSET_INLINE): Remove.
16125 * lib/bitset.h [! BITSET_INLINE]: Remove.
16126 (bitset_set, bitset_reset, bitset_test): Rename local vars
16127 to avoid shadowing warnings by GCC.
16129 * data/glr.c (inline): Remove #define. It's the user's
16130 responsibility to #define it away, just like 'const'.
16131 This fixes one of the bugs reported by Nelson H. F. Beebe in
16132 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
16134 * Makefile.maint (po-check): Scan .l and .y files instead of the
16135 .c and the .h files that they generate. This fixes the bug
16136 reported by Tim Van Holder in:
16137 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
16138 Look for N_ as well as for _. Try to avoid matching #define for

16143 do not confuse xgettext.
16145 * src/struniq.h (struniq_new): Do not declare the return type
16146 to be 'const'; this violates the C standard.
16147 * src/struniq.c (struniq_new): Likewise.
16149 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
16151 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

16157 * Makefile.maint: Sync with Autoconf:

16183 * data/glr.c (yystos): New.
16184 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
16185 (YYDSYMPRINT): New.
16186 (yyval): Don't define it, it is handled via M4.
16187 (yyrecoverParseError): Free verbosely the discarded symbols.
16188 * data/yacc.c (yysymprint): Remove, rather...
16189 (b4_yysymprint_generate): invoke.

16194 * tests/cations.at (Printers and Destructors): Use Bison directives
16195 instead of CPP macros.
16196 Don't rely on internal details.

16200 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
16201 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
16202 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
16203 it against YYEMPTY and so forth), work on yytoken (i.e., set
16204 it to YYEMPTY etc.).
16205 (yydestruct): Replace with a b4_yydestruct_generate invocation.
16206 (b4_symbol_actions): Remove.
16207 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
16208 for 0, end-of-input.

16214 2002-11-12 Akim Demaille <akim@epita.fr>
16216 * src/tables.c (tables_generate): Use free for pointers that
16217 cannot be NULL, not XFREE.

16295 Revamp to fix many (but not all) of the C- and M4-related quoting
16296 problems. Among other things, this fixes the Bison bug reported
16297 by Jan Hubicka when processing the Bash grammar; see:
16298 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
16300 Use new @ escapes consistently. Represent brackets with @{ and @}
16301 rather than @<:@ and @:>@, since this works a bit better with dumb
16302 editors like vi. Represent @ with @@, since @ is now consistently
16303 an escape. Use @oline@ and @ofile@ rather than __oline__ and
16304 __ofile__, to avoid unexpected expansions. Similarly, use @output
16305 rather than #output.
16307 * data/c.m4 (b4_copyright): Omit file name from comment, since
16308 the file name could contain "*/".
16309 (b4_synclines_flag): Don't quote the 2nd argument; it should already
16310 be quoted. All uses changed.
16312 * data/glr.c: Use new @ escapes consistently.
16313 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
16314 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
16315 Remove, since they couldn't handle arbitrary characters in file
16317 * data/lalr1.cc: Likewise.
16318 * data/yacc.c: Likewise.
16320 * src/files.c (output_infix): Remove; all uses removed.
16321 * src/files.h: Likewise.
16323 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
16324 mishandled funny characters in file names, and anyway it isn't
16326 * data/yacc.c: Likewise.
16327 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
16329 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
16330 * data/yacc.c: Likewise.
16332 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
16334 (muscle_init): Quote filename as a C string.
16335 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
16336 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
16337 * src/output.c (escaped_file_name_output): New function.
16338 (prepare_symbols): Quote tokens for M4.
16339 (prepare): Don't insert output_infix, output_prefix,
16340 output_parser_name, output_header_name; this is now down by scan-skel.
16341 Insert skeleton as a C string.
16343 * src/output.c (user_actions_output, symbol_destructors_output,
16344 symbol_printers_output): Quote filenames for C and M4.
16345 * src/reader.c (prologue_augment, epilogue_set): Likewise.
16347 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
16348 escapes other than \\ and \'; this simplifies the code.
16349 (<SC_STRING>): Likewise, for \\ and \".
16350 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
16351 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
16352 Use new escapes @{ and @} for [ and ].
16354 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
16355 them with auto vars.
16356 Switch to new escape scheme, where @ is the escape character uniformly.
16357 Abort if a stray escape character is found. Avoid unbounded input
16358 buffer when parsing non-escaped text.
16360 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
16361 __oline__, #output, $@, and @{ do not have unintended meanings.
16363 2002-11-09 Paul Eggert <eggert@twinsun.com>
16365 Fix the test failure due to GCC warnings described in
16366 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
16367 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
16368 evaluate to 0 if it's impossible for NINF to be in the respective
16370 (yygetLRActions, yyrecoverParseError): Use them.
16372 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
16373 counted in the token inserted at end of file. Now takes
16374 location_t *, not location_t, so that the location can be
16375 adjusted. All uses changed.
16377 * tests/regression.at (Invalid inputs): Adjust wording in
16378 diagnostic to match the new behavior.
16380 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
16381 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
16382 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
16383 abort ();'. This reduces the runtime of the "Many lookaheads"
16384 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
16387 2002-11-07 Paul Eggert <eggert@twinsun.com>
16389 * src/parse-gram.y (CHARACTER): Remove unused token.
16392 * src/scan-gram.l: Remove stack option. We no longer use the
16393 stack, since the stack was never deeper than 1; instead, use the
16394 new auto var c_context to record the stacked value.
16396 Remove nounput option. At an unexpected end of file, we now unput
16397 the minimal input necessary to end cleanly; this simplifies the
16400 Avoid unbounded token sizes where this is easy.
16402 (unexpected_end_of_file): New function.
16403 Use it to systematize the error message on unexpected EOF.
16404 (last-string): Now auto, not static.
16405 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
16406 (scanner_last_string_free): Remove; not used.
16407 (percent_percent_count): Move decl to just before use.
16408 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
16409 not the (never otherwised-used) CHARACTER.
16411 2002-11-07 Akim Demaille <akim@epita.fr>
16413 Let yyerror always receive the msg as last argument, so that
16414 yyerror can be variadic.
16416 * data/yacc.c (b4_yyerror_args): New.
16417 Use it when calling yyerror.
16418 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

16422 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
16424 2002-11-06 Akim Demaille <akim@epita.fr>
16426 #line should have quoted strings.
16427 Ideally, this should be done by m4_quotearg.
16429 * src/scan-skel.l: Include quotearg.h.
16431 * src/output.c (symbol_printers_output)
16432 (symbol_destructors_output): Quote the file name.
16434 2002-11-06 Akim Demaille <akim@epita.fr>

16447 * src/output.c (user_actions_output): Likewise.
16448 (prepare): Define 'b4_synclines_flag'.
16449 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
16451 2002-11-06 Akim Demaille <akim@epita.fr>

16454 * src/scan-gram.l (handle_syncline): New.
16456 * src/output.c (user_actions_output, symbol_destructors_output)
16457 (symbol_printers_output): Use the location's file name, not
16459 * src/reader.c (prologue_augment, epilogue_set): Likewise.
16461 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
16463 * src/tables.c (matching_state): Don't allow states to match if
16464 either has GLR conflict entries.
16466 2002-11-05 Paul Eggert <eggert@twinsun.com>
16468 * src/scan-gram.l: Use more accurate diagnostics, e.g.
16469 "integer out of range" rather than "invalid value".
16470 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
16473 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
16474 Also, remove one static variable in the scanner.
16476 * src/scan-gram.l (braces_level): Now auto, not static.
16477 Initialize to zero if the compiler is being picky.
16478 (INITIAL): Clear braces_level instead of incrementing it.
16479 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
16480 as POSIX 1003.1-2001 requires.
16481 * src/system.h (IF_LINT): New macro, taken from coreutils.
16482 * configure.ac: Define "lint" if --enable-gcc-warnings.
16484 2002-11-05 Akim Demaille <akim@epita.fr>
16486 * src/scan-gram.l: When it starts with `%', complain about the
16487 whole directive, not just that `invalid character: %'.
16489 2002-11-04 Akim Demaille <akim@epita.fr>
16491 * Makefile.maint: Update from Autoconf.
16492 (update, cvs-update, po-update, do-po-update): New.
16494 2002-11-04 Akim Demaille <akim@epita.fr>
16496 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
16498 Have yyerror `use' its arguments.
16499 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
16500 returns true when location & yacc & pure & parse-param.
16501 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
16503 2002-11-04 Akim Demaille <akim@epita.fr>

16507 * src/scan-gram.l: Use [\'] instead of ['] to pacify
16510 Use quote, not quote_n since LOCATION_PRINT no longer uses the
16513 2002-11-03 Paul Eggert <eggert@twinsun.com>
16515 * src/reader.c (get_merge_function, grammar_current_rule_check):
16516 Use consistent diagnostics for reporting type name clashes.
16517 Quote the types with <>, for consistency with Yacc.
16518 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
16520 2002-11-03 Akim Demaille <akim@epita.fr>
16522 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
16524 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
16525 (b4_parse_param): Remove.
16526 Use b4_identification.
16527 Propagate b4_pure_args where needed to pass them to yyerror.
16528 * data/glr.m4 (b4_parse_param): Remove.
16529 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

16532 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
16533 b4_user_formals and b4_user_args.
16534 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
16535 (yyreportAmbiguity): When using a pure parser, also need
16536 the location, and the parse-params.
16538 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
16539 When using a pure parser, also need the parse-params.
16541 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
16542 (%pure-parser + %parse-param) LALR and GLR parsers.
16543 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
16544 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
16545 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
16546 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
16547 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
16548 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
16549 * doc/bison.texinfo: Untabify the whole file.
16550 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
16551 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
16552 (Error Reporting): Adjust to these new directives.
16553 Document %error-verbose, deprecate YYERROR_VERBOSE.
16555 2002-11-03 Akim Demaille <akim@epita.fr>
16557 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
16558 AT_CHECK_CALC_GLR invocations to use % directives, instead of
16559 command line options.
16560 * tests/cxx-type.at: Formatting changes.
16562 2002-11-03 Paul Eggert <eggert@twinsun.com>
16564 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
16565 to count columns correctly, and to check for invalid inputs.
16567 Use mbsnwidth to count columns correctly. Account for tabs, too.
16568 Include mbswidth.h.
16569 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
16570 (extend_location): New function.
16571 (YY_LINES): Remove.
16573 Handle CRLF in C code rather than in Lex code.
16574 (YY_INPUT): New macro.
16575 (no_cr_read): New function.
16577 Scan UCNs, even though we don't fully handle them yet.

16580 Handle backslash-newline correctly in C code.
16581 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
16582 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
16584 (tag, splice): New EREs. Do not allow NUL or newline in tags.
16585 Use {splice} wherever C allows backslash-newline.
16586 YY_STEP after space, newline, vertical-tab.
16587 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
16589 (letter, id): Don't assume ASCII; e.g., spell out a-z.
16591 ({int}, handle_action_dollar, handle_action_at): Check for integer
16594 (YY_STEP): Omit trailing semicolon, so that it's more like C.
16596 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
16597 as well as \000. Check for UCHAR_MAX, not 255.
16598 Allow \x with an arbitrary positive number of digits, as in C.
16599 Check for overflow here.
16600 Allow \? and UCNs, for compatibility with C.
16602 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
16603 with quote slot used by complain_at.
16605 * tests/input.at: Add tests for backslash-newline, m4 quotes
16606 in symbols, long literals, and funny escapes in strings.
16608 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
16609 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
16610 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
16611 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
16612 * m4/mbswidth.m4: New file, from GNU coreutils.
16614 * doc/bison.texinfo (Grammar Outline): Document // comments.
16615 (Symbols): Document that trigraphs have no special meaning in Bison,
16616 nor is backslash-newline allowed.
16617 (Actions): Document that trigraphs have no special meaning.
16619 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
16622 2002-11-02 Paul Eggert <eggert@twinsun.com>
16624 * src/reader.c: Don't include quote.h; not needed.
16625 (get_merge_function): Reword warning to be consistent with
16626 type clash diagnostic in grammar_current_rule_check.
16628 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
16629 bug in trigraph handling.
16631 * src/output.c (prepare_symbols): When printing token names,
16632 escape "[" as "@<:@" and likewise for "]".
16634 * src/system.h (errno): Remove declaration, as we are now
16635 assuming C89 or better, and C89 guarantees errno.
16637 2002-10-30 Paul Eggert <eggert@twinsun.com>
16639 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
16640 Check for close failures.
16641 * src/files.h (xfclose): Return void, not int, since it always
16643 * src/files.c (xfclose): Likewise. Report I/O error if ferror
16645 * src/output.c (output_skeleton): Use xfclose rather than fclose
16646 and ferror. xfclose now checks ferror.
16648 * data/glr.c (YYLEFTMOST_STATE): Remove.
16649 (yyreportTree): Use a stack-based leftmost state. This avoids
16650 our continuing battles with bogus warnings about initializers.
16652 2002-10-30 Akim Demaille <akim@epita.fr>
16654 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

16659 * tests/glr-regr1.at: New test for reported regressions.
16660 * tests/testsuite.at: Add glr-regr1.at test.
16661 * tests/Makefile.am: Add glr-regr1.at test.

16667 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
16668 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
16669 we use malloc. Don't assume 'A' through 'Z' are contiguous.
16670 Don't assume strdup exists; POSIX says its an XSI extension.
16671 Check for buffer overflow on input.
16673 2002-10-24 Akim Demaille <akim@epita.fr>
16675 * src/output.c (output_skeleton): Don't disable M4sugar comments
16676 too soon: it results in comments being expanded.
16677 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
16680 2002-10-24 Akim Demaille <akim@epita.fr>
16682 * data/yacc.c (m4_int_type): New.
16683 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
16684 char' as only yacc.c wants K&R portability.
16685 * data/glr.c (yysigned_char): Remove.
16686 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
16687 Reported by Quoc Peyrot.
16689 2002-10-23 Paul Eggert <eggert@twinsun.com>
16691 * src/main.c (main): With --trace=time, report times even if a
16692 non-fatal error occurs. Formerly, the times were reported in some
16693 such cases but not in others.
16694 * src/reader.c (reader): Just return if a complaint has been issued,
16695 instead of exiting, so that 'main' can report times.
16697 2002-10-22 Akim Demaille <akim@epita.fr>
16699 * src/system.h: Include sys/types.
16700 Reported by Bert Deknuydt.
16702 2002-10-23 Paul Eggert <eggert@twinsun.com>
16704 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
16705 Suggested by Art Haas.
16707 2002-10-22 Paul Eggert <eggert@twinsun.com>
16709 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
16710 decl; not needed any more.
16711 * src/main.c (main): Use return to exit, undoing yesterday's change.
16712 The last OS that we could find where this wouldn't work is
16713 SunOS 3.5, and that's too old to worry about now.
16715 * data/glr.c (struct yyltype): Define members even when not
16716 doing locations. This is more consistent with yacc.c, and it
16717 works around the following bug reports:
16718 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
16719 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
16721 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
16722 @acronym consistently. Standardize on "Yacc" instead of "YACC",
16723 "Algol" instead of "ALGOL". Give a bit more history about BNF.
16725 2002-10-22 Akim Demaille <akim@epita.fr>
16727 * data/README: New.
16729 2002-10-21 Paul Eggert <eggert@twinsun.com>
16731 Be consistent about 'bool'; the old code used an enum in one
16732 module and an int in another, and this violates the C standard.
16733 * m4/stdbool.m4: New file, from coreutils 4.5.3.
16734 * configure.ac (AC_HEADER_STDBOOL): Add.
16735 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
16736 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
16737 * src/symtab.c (hash_compare_symbol_t): Likewise.
16738 * src/system.h (bool, false, true): Use a definition consistent
16739 with ../lib/hash.c. All uses changed.
16741 * src/complain.c (warning_issued): Renamed from warn_message_count,
16742 so that we needn't worry about integer overflow (!).
16743 Now of type bool. All uses changed.
16744 (complaint_issued): Renamed from complain_message_count; likewise.
16746 * src/main.c (main): Use exit to exit with failure.
16748 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
16749 rather than 1 and 0.
16750 * src/main.c (main): Likewise.
16751 * src/getargs.c (getargs): Likewise.
16752 * src/reader.c (reader): Likewise.
16754 * src/getarg.c (getargs): Remove duplicate code for
16755 "Try `bison --help'".
16757 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
16758 What was that "2" for?
16760 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
16761 * src/getargs.c (usage): Likewise.
16763 * src/getargs.c (getargs): When there are too few operands, report
16764 the last one. When there are too many, report the first extra
16765 one. This is how diffutils does it.
16767 2002-10-20 Paul Eggert <eggert@twinsun.com>
16769 Remove K&R vestiges.
16770 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

16774 fatal): Assume prototypes.
16775 * src/complain.h: Assume prototypes.
16776 * src/system.h (PARAMS): Remove.
16777 Include <limits.h> unconditionally, since it's guaranteeed even
16778 for a freestanding C89 compiler.
16779 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
16780 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
16782 2002-10-20 Akim Demaille <akim@epita.fr>

16787 (yyresolveStates, yyresolveAction, yyresolveStack)
16788 (yyprocessOneStack): Use them.
16789 (yy_reduce_print): New.
16790 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.

16794 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
16795 arguments and output `void'.
16796 (b4_c_function): Rename as...
16797 (b4_c_function_def): this.
16798 (b4_c_function_decl, b4_c_ansi_function_def)
16799 (b4_c_ansi_function_decl): New.
16800 Change the interpretation of the arguments: before `int, foo', now

16803 Adjust b4_c_function_def uses.
16804 * data/glr.c (yyparse): Likewise, but ANSI only.

16813 (prepare_symbols): this.
16814 (prepare): Move the definition of `rules_number' to...
16815 (prepare_rules): here.
16816 (prepare): Move the definition of `last', `final_state_number',
16817 `states_number' to...
16818 (prepare_states): here.
16819 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
16821 2002-10-20 Akim Demaille <akim@epita.fr>
16823 * src/tables.h, src/tables.c, src/output.c: Comment changes.
16825 2002-10-20 Akim Demaille <akim@epita.fr>

16838 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
16841 2002-10-19 Paul Eggert <eggert@twinsun.com>
16843 Do not create a temporary file, as that involves security and
16844 cleanup headaches. Instead, use a pair of pipes.
16845 Derived from a suggestion by Florian Krohm.
16846 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
16847 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
16848 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
16849 (BISON_PREREQ_SUBPIPE): Add.
16850 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
16851 Add subpipe.h, subpipe.c.

16856 (scan_skel): New decl.
16857 (output_skeleton): Use pipe rather than temporary file for m4 input.

16859 Check for pipe I/O error.
16860 * src/scan-skel.l (readpipe): Remove decl.
16861 (scan_skel): New function, to be used in place of m4_invoke.
16862 Read from stream rather than file.
16864 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
16865 float, as this generates a warning on Solaris 8 + GCC 3.2 with
16866 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
16867 this generates a more-accurate value anyway.
16869 * lib/timevar.c (timervar_accumulate): Rename locals to
16870 avoid confusion with similarly-named more-global.
16871 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
16873 * src/output.c (prepare): Use xstrdup to convert char const *
16874 to char *, to avoid GCC warning.
16876 2002-10-19 Akim Demaille <akim@epita.fr>
16878 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
16879 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
16880 Use them to have `calc.y' ready for %pure-parser.
16881 * data/yacc.c (YYLEX): Pass a yylex return type to
16882 b4_c_function_call.
16884 2002-10-19 Akim Demaille <akim@epita.fr>
16886 Prototype support of %lex-param and %parse-param.
16888 * src/parse-gram.y: Add the definition of the %lex-param and
16889 %parse-param tokens, plus their rules.
16890 Drop the `_' version of %glr-parser.
16892 * src/scan-gram.l (INITIAL): Scan them.
16893 * src/muscle_tab.c: Comment changes.
16894 (muscle_insert, muscle_find): Rename `pair' as `probe'.
16895 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
16896 (muscle_entry_s): The `value' member is no longer const.
16897 Adjust all dependencies.
16898 * src/muscle_tab.c (muscle_init): Adjust: use
16899 MUSCLE_INSERT_STRING.
16900 Initialize the obstack earlier.
16901 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
16902 (muscle_pair_list_grow): New.
16903 * data/c.m4 (b4_c_function_call, b4_c_args): New.
16904 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
16905 * tests/calc.at: Use %locations, not --locations.
16906 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
16908 2002-10-19 Akim Demaille <akim@epita.fr>
16910 * src/getargs.c (usage): Take status as argument and exit
16912 Report the traditional `Try ... --help' message when status != 0.
16913 (usage, version): Don't take a FILE * as arg, it is pointless.
16914 (getargs): When there is an incorrect number of arguments, make it
16915 an error, and report it GNUlically thanks to `usage ()'.
16917 2002-10-18 Paul Eggert <eggert@twinsun.com>
16919 * data/glr.c (yyreportParseError): Don't assume that sprintf
16920 yields the length of the printed string, as this is not true
16921 on SunOS 4.1.4. Reported by Peter Klein.
16923 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
16924 * tests/conflicts.at (%nonassoc and eof): Likewise.
16925 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
16927 2002-10-17 Akim Demaille <akim@epita.fr>
16929 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
16930 * src/getargs.c (trace_types, trace_args): Adjust.
16931 * src/reader.c (grammar_current_rule_prec_set)
16932 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
16933 Standardize error messages.
16934 And s/@prec/%prec/!
16935 (reader): Use trace_flag to enable scanner/parser debugging,
16936 instead of an adhoc scheme.
16937 * src/scan-gram.l: Remove trailing debugging code.
16939 2002-10-16 Paul Eggert <eggert@twinsun.com>
16941 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
16944 * NEWS: Officially drop support for building Bison with K&R C,
16945 since it didn't work anyway and it's not worth worrying about.
16946 * Makefile.maint (wget_files): Remove ansi2knr.c.
16947 (ansi2knr.c-url_prefix): Remove.
16948 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
16949 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
16950 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
16952 2002-10-15 Paul Eggert <eggert@twinsun.com>
16954 Stop using the "enum_" trick for K&R-style function definitions;
16955 it confused me, and I was the author! Instead, assume that people
16956 who want to use K&R C compilers (when using these modules in GCC,
16957 perhaps?) will run ansi2knr.
16959 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
16960 All uses of "enum_" changed to "enum ".
16961 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
16962 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
16964 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

16971 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
16972 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
16973 Use function prototypes; this removes the need for declaring
16974 static functions simply to provide their prototypes.
16975 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

17032 2002-10-14 Akim Demaille <akim@epita.fr>
17034 * tests/Makefile.am (maintainer-check-posix): New.
17036 2002-10-14 Akim Demaille <akim@epita.fr>
17038 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
17041 2002-10-14 Akim Demaille <akim@epita.fr>
17043 * src/tables.c (table_ninf_remap): base -> tab.
17044 Reported by Matt Rosing.
17046 2002-10-14 Paul Eggert <eggert@twinsun.com>
17048 * tests/action.at, tests/calc.at, tests/conflicts.at,
17049 tests/cxx-type.at, tests/headers.at, tests/input.at,
17050 tests/regression.at, tests/synclines.at, tests/torture.at:
17051 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
17052 so that the tests still work even if POSIXLY_CORRECT is set.
17053 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
17055 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
17056 for portability to K&R hosts. Fix typo: signed char is guaranteed
17057 only to 127, not to 128.
17058 * data/glr.c (yysigned_char): New type.
17059 * data/yacc.c (yysigned_char): Likewise.
17060 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
17062 2002-10-13 Paul Eggert <eggert@twinsun.com>
17064 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
17065 true due to limited range of data type" warning from GCC.
17067 * data/c.m4 (b4_token_defines): Protect against double-inclusion
17068 by wrapping enum yytokentype's definition inside #ifndef
17069 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
17071 2002-10-13 Akim Demaille <akim@epita.fr>
17073 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
17074 Un yy- yyrhs to avoid the name clash with the global YYRHS.
17076 2002-10-13 Akim Demaille <akim@epita.fr>
17078 * Makefile.maint: Update from Autoconf 2.54.
17079 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
17081 2002-10-13 Akim Demaille <akim@epita.fr>
17083 * src/print.c (print_state): Separate the list of solved conflicts
17084 from the other items.
17085 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
17087 2002-10-13 Akim Demaille <akim@epita.fr>
17089 Let nondeterministic skeletons be usable with deterministic
17092 With the patch, GAWK compiled by GCC without -O2 passes its test
17093 suite using a GLR parser driven by LALR tables. It fails with -O2
17094 because `struct stat' gives two different answers on my machine:
17095 88 (definition of an auto var) and later 96 (memset on this var).
17096 Hence the stack is badly corrumpted. The headers inclusion is to
17097 blame: if I move the awk.h inclusion before GLR's system header
17098 inclusion, the two struct stat have the same size.
17100 * src/tables.c (pack_table): Always create conflict_table.
17101 (token_actions): Always create conflict_list.
17102 * data/glr.c (YYFLAG): Remove, unused.
17104 2002-10-13 Akim Demaille <akim@epita.fr>
17106 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
17108 (VALGRIND, GXX): New.
17109 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
17110 * tests/bison.in: Run $PREBISON a pre-command.
17111 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
17112 (maintainer-check-g++): New.
17113 * Makefile.am (maintainer-check): New.
17115 2002-10-13 Akim Demaille <akim@epita.fr>
17117 * data/glr.c: Formatting changes.
17118 Tweak some trace messages to match yacc.c's.
17120 2002-10-13 Akim Demaille <akim@epita.fr>
17122 GLR parsers sometimes raise parse errors instead of performing the
17124 Reported by Charles-Henry de Boysson.
17126 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
17127 check the length of the traces when %glr.
17128 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
17130 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
17132 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
17133 (yyltype): Remove the yy prefix from the member names.
17134 (yytable): Complete its comment.
17135 (yygetLRActions): Map error action number from YYTABLE from
17137 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
17138 (which was a bug: it should have been YYTABEL_NINF, and yet it was
17139 not satisfying as we could compare an YYACTION computed from
17140 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
17141 only value for error actions.
17142 (yyreportParseError): In verbose parse error messages, don't issue
17143 `error' in the list of expected tokens.
17144 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
17145 next action to perform to match glr.c's decoding.
17146 (yytable): Complete its comment.
17148 2002-10-13 Paul Eggert <eggert@twinsun.com>
17150 Fix problem reported by Henrik Grubbstroem in
17151 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
17152 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
17153 because the Bison parser reads the second action before reducing
17155 * src/scan-gram.l (rule_length): New static var.
17156 Use it to keep track of the rule length in the scanner, since
17157 we can't expect the parser to be in lock-step sync with the scanner.
17158 (handle_action_dollar, handle_action_at): Use this var.
17159 * tests/actions.at (Exotic Dollars): Test for the problem.
17161 2002-10-12 Paul Eggert <eggert@twinsun.com>
17163 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
17164 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
17165 Include <sys/time.h> when checking for clock_t and struct tms.

17167 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
17168 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
17170 * lib/timevar.c: Update copyright date and clarify comments.
17171 (get_time) [IN_GCC]: Keep the GCC version for reference.
17173 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
17174 GCC version as of today, then merge Bison's changes.
17175 Change "GCC" to "Bison" in copyright notice. timevar.def's
17176 author is Akim, so change that too.
17178 * src/reader.c (grammar_current_rule_check):
17179 Don't worry about the default action if $$ is untyped.
17180 Prevents bogus warnings reported by Jim Gifford in

17189 2002-10-11 Paul Eggert <eggert@twinsun.com>
17191 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
17192 (yyparse): here. This undoes some of the 2002-07-25 change.
17193 Compatibility problem reported by Ralf S. Engelschall with
17194 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

17212 * lib/abitset.c: Include <stddef.h>, for offsetof.
17213 * lib/lbitset.c: Likewise.
17215 * lib/abitset.c (abitset_bytes): Return a size that is aligned
17216 properly for vectors of objects. Do not assume that adding a
17217 header size to a multiple of a word size yields a value that is
17218 properly aligned for the whole union.
17219 * lib/bitsetv.c (bitsetv_alloc): Likewise.
17221 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
17222 unique names for structures.

17224 * lib/lbitset.c (lbitset_bytes): Likewise.
17226 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

17231 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
17232 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
17233 to improve the type-checking that GCC can do.
17234 * lib/bitset.c (bitset_op4_cmp): Likewise.
17235 * lib/bitset_stats.c (bitset_stats_count,
17236 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

17252 * lib/lbitset.h: Likewise.
17254 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
17255 All instances of parameters of type enum bitset_opts are now of
17256 type enum_bitset_opts, to conform to the C Standard, and similarly
17257 for enum_bitset_type.
17258 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
17259 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
17261 Do not use "struct bitset_struct" to mean different things in
17262 different modules. Not only is this confusing, it violates
17263 the C Standard, which requires that structure types in different
17264 modules must be compatible if one is to be passed to the other.
17265 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
17266 All instances of "struct bitset_struct *" replaced with "bitset".
17267 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
17268 (union bitset_union, struct abitset_struct, struct ebitset_struct,

17276 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
17277 bitset_struct): Remove.
17278 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
17281 Do not call a function of type T using a call that assumes the
17282 function is of a different type U. Standard C requires that a
17283 function must be called with a type that is compatible with its
17285 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17287 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
17289 * lib/ebitset.c (PFV): Remove.
17290 * lib/lbitset.c (PFV): Likewise.

17300 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
17303 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
17305 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
17306 Use offsetof, for simplicity.
17308 2002-10-06 Paul Eggert <eggert@twinsun.com>
17310 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
17311 the same width as int. This reapplies a hunk of the 2002-08-12 patch
17312 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
17313 which was inadvertently undone by the 2002-09-30 patch.
17314 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
17315 the same width as int.
17317 2002-10-04 Paul Eggert <eggert@twinsun.com>
17321 * configure.ac (AC_INIT), NEWS: Increment version number.
17323 * doc/bison.texinfo: Minor spelling, grammar, and white space
17325 (Symbols): Mention that any negative value returned from yylex
17326 signifies end-of-input. Warn about negative chars. Mention
17327 the portable Standard C character set.

17342 POSIX 1003.1-2001 has removed fgrep.
17344 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

17627 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't

17673 outside the C locale.
17675 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
17676 this is a GCC extension and is not portable to other compilers.

17689 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
17690 exit status as failure, not just exit status 1. Sun C exits
17691 with status 2 sometimes.

17861 parsers now contain `reduce 0' as default reduction.
17862 Nevertheless, since they decide to `accept' when yystate =

17912 token_translations instead of `0'.
17913 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
17915 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
17916 for the time being: %locations ought to provide it to yyerror.
17918 2002-07-25 Akim Demaille <akim@epita.fr>
17920 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

17935 Handle the `- 1' part in rule numbers from/to item numbers.

19535 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
19536 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
19537 constructors or destructors.
19539 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.

19565 * data/bison.c++ (r1_): Likewise.
19566 * tests/regression.at (Web2c Actions): Adjust.
19568 2002-04-22 Akim Demaille <akim@epita.fr>
19570 * src/reader.c (token_translations_init): 256 is now the default
19571 value for the error token, i.e., it will be assigned another
19572 number if the user assigned 256 to one of her tokens.
19573 (reader): Don't force 256 to error.
19574 * doc/bison.texinfo (Symbols): Adjust.

19576 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
19577 etc. instead of 10, 20, 30 (which was used to `jump' over error
19578 (256) and undefined (2)).
19580 2002-04-22 Akim Demaille <akim@epita.fr>

19617 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
19618 full stderr, and strip it according to the bison options, instead
19619 of composing the error message from different bits.
19620 This makes it easier to check for several error messages.
19621 Adjust all the invocations.
19622 Add an invocation exercising the error token.
19623 Add an invocation demonstrating a stupid error message.
19624 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

19636 (state_t.number): Is a token_number_t.

19642 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
19643 `user_token_number_max'.
19644 Output `undef_token_number'.

19682 * tests/regression.at (Web2c Actions): Ajust.
19684 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
19685 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
19686 passes, but produces negative #line number, once fixed, GCC is
19687 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

19889 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
19890 lacking `+ 1' to nrules, Bison reported as useless a token if it
19891 was used solely to set the precedence of the last rule...
19893 2002-04-07 Akim Demaille <akim@epita.fr>
19895 * data/bison.c++, data/bison.simple: Don't output the current file
19896 name in #line, to avoid useless diffs between two identical
19897 outputs under different names.
19899 2002-04-07 Akim Demaille <akim@epita.fr>
19901 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

19916 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
19917 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
19918 RHS, instead of being an index in RITEMS.
19920 2002-04-04 Paul Eggert <eggert@twinsun.com>
19922 * doc/bison.texinfo: Update copyright date.
19923 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

20187 2002-02-14 Paul Eggert <eggert@twinsun.com>
20189 Remove the support for C++ namespace cleanliness; it was
20190 causing more problems than it was curing, since it didn't work
20191 properly on some nonstandard C++ compilers. This can wait
20192 for a proper C++ parser.
20194 * NEWS: Document this.
20195 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
20196 of C++, as it's treated like C now.

20212 * src/output.c (output_rule_data): Don't output NULL, it might
20213 not be defined yet.
20215 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
20217 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.

20234 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20236 * data/bison.c++: Replace some direct m4 expansions by constants. Be
20237 more consistent when naming methods and variables. Put preprocessor
20238 directives around tables only needed for debugging.
20240 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20242 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
20244 (yy::b4_name::parse): Use print_.
20246 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20248 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
20250 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
20252 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
20254 (yy::b4_name::parse): Build verbose error messages, and use error_.

20265 2002-02-05 Akim Demaille <akim@epita.fr>
20267 * data/bison.c++: Adjust to the M4 back end.
20268 More is certainly needed.
20270 2002-02-05 Akim Demaille <akim@epita.fr>
20272 Give a try to M4 as a back end.
20274 * lib/readpipe.c: New, from wdiff.
20275 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
20277 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
20278 specific values. Now it is m4 that performs the lookup.
20279 * src/parse-skel.y: Remove.
20280 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
20281 * src/output.c (actions_output, guards_output)
20282 (token_definitions_output): No longer keeps track of the output
20283 line number, hence remove the second argument.
20284 (guards_output): Check against the guard member of a rule, not the
20287 (output_skeleton): Don't look for the skeleton location, let m4 do
20289 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
20291 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
20292 (prepare): Given that for the time being changesyntax is not
20293 usable in M4, rename the muscles using `-' to `_'.
20294 Define `defines_flag', `output_parser_name' and `output_header_name'.
20295 * src/output.h (actions_output, guards_output)
20296 (token_definitions_output): Adjust prototypes.
20297 * src/scan-skel.l: Instead of scanning the skeletons, it now
20298 processes the output of m4: `__oline__' and `#output'.
20299 * data/bison.simple: Adjust to be used by M4(sugar).
20300 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
20302 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
20303 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
20304 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
20305 shamelessly stolen from CVS Autoconf.
20307 2002-02-05 Akim Demaille <akim@epita.fr>
20309 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
20310 * configure.in: Check for the declarations of free and malloc.
20311 * src/muscle_tab.c: Adjust.
20313 2002-02-05 Akim Demaille <akim@epita.fr>
20315 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
20316 which have no values.
20318 2002-02-05 Akim Demaille <akim@epita.fr>
20320 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
20323 2002-01-29 Paul Eggert <eggert@twinsun.com>
20325 * src/bison.simple (YYSIZE_T): Do not define merely because
20326 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
20327 On some platforms, <alloca.h> does not declare YYSTD (size_t).
20329 2002-01-27 Akim Demaille <akim@epita.fr>
20331 Fix `%nonassoc and eof'.
20333 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
20334 which were not properly copied! Replace
20335 memcpy (res->errs, src->errs, src->nerrs);
20337 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
20339 * tests/regression.at (%nonassoc and eof): Adjust to newest
20340 Autotest: `.' is not in the PATH.
20342 2002-01-27 Akim Demaille <akim@epita.fr>
20344 * tests/sets.at (AT_EXTRACT_SETS): New.
20345 (Nullable): Use it.
20348 2002-01-26 Akim Demaille <akim@epita.fr>
20350 * tests/actions.at, tests/calc.at, tests/headers.at,
20351 * tests/torture.at: Adjust to the newest Autotest which no longer
20352 forces `.' in the PATH.
20354 2002-01-25 Akim Demaille <akim@epita.fr>
20356 * tests/regression.at (%nonassoc and eof): New.
20357 Suggested by Robert Anisko.
20359 2002-01-24 Akim Demaille <akim@epita.fr>
20361 Bison dumps core when trying to complain about broken input files.
20362 Reported by Cris van Pelt.
20364 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
20365 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
20367 (Invalid inputs): Strengthen: exercise parse_percent_token.

20371 * src/Makefile.am: Add bison.c++.
20372 * src/bison.c++: New skeleton.
20374 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
20378 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
20380 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
20382 2002-01-20 Marc Autret <marc@gnu.org>
20384 * src/files.c (compute_output_file_names): Fix
20386 2002-01-20 Marc Autret <marc@gnu.org>
20388 * tests/output.at: New test.
20389 * src/files.c (compute_base_names): Don't map extensions when
20390 the YACC flag is set, use defaults.
20391 Reported by Evgeny Stambulchik.
20393 2002-01-20 Marc Autret <marc@gnu.org>
20395 * src/system.h: Need to define __attribute__ away for non-GCC
20396 compilers as well (i.e., the vendor C compiler).
20397 Suggested by Albert Chin-A-Young.
20399 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
20401 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
20402 canonical definition.
20403 * src/system.h: Use the canonical definition for PARAMS (avoids
20404 a conflict with the macro from lib/hash.h).
20406 2002-01-11 Akim Demaille <akim@epita.fr>
20408 * configure.in: Use AC_FUNC_STRNLEN.
20409 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.

20413 * src/files.c, src/files.h (output_infix): New.
20414 (tab_extension): Remove.
20415 (compute_base_names): Compute the former, drop the latter.
20416 * src/output.c (prepare): Insert the muscles `output-infix', and
20418 * src/parse-skel.y (string, string.1): New.
20419 (section.header): Use it.
20420 (section.yacc): Remove.
20421 (prefix): Remove too.
20422 * src/scan-skel.l: Adjust.

20427 * configure.in (WERROR_CFLAGS): Compute it.
20428 * src/Makefile.am (CFLAGS): Pass it.
20429 * tests/atlocal.in (CFLAGS): Idem.
20430 * src/files.c: Fix a few warnings.
20431 (get_extension_index): Remove, unused.
20433 2002-01-08 Akim Demaille <akim@epita.fr>

20436 (getargs): Use it to convert DOSish file names.
20437 * src/files.c (base_name): Rename as full_base_name to avoid
20438 clashes with `base_name ()'.
20439 (filename_split): New.
20440 (compute_base_names): N-th rewrite, using filename_split.
20442 2002-01-08 Akim Demaille <akim@epita.fr>
20444 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:

20447 * configure.in: Check for the presence of memrchr, and of its
20450 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
20452 * lib/hash.h (__P): Added definition for this macro.
20453 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
20454 BUILT_SOURCES, to ensure they are generated first.
20455 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
20456 %error-verbose to allow bootstrapping with bison 1.30x.
20458 2002-01-06 Akim Demaille <akim@epita.fr>
20460 * src/reader.c (parse_braces): Don't fetch the next char, the
20461 convention is to fetch on entry.
20462 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
20463 'switch' without a following semicolon.
20464 * tests/regression.at (braces parsing): New.
20466 2002-01-06 Akim Demaille <akim@epita.fr>
20468 Bison is dead wrong in its RR conflict reports.
20470 * tests/torture.at (GNU Cim Grammar): New.
20471 * src/conflicts.c (count_rr_conflicts): Fix.
20473 2002-01-06 Akim Demaille <akim@epita.fr>
20475 Creating package.m4 from configure.ac causes too many problems.
20477 * tests/Makefile.am (package.m4): Create it by hand,
20478 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
20480 2002-01-06 Akim Demaille <akim@epita.fr>
20482 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
20485 2002-01-04 Paul Eggert <eggert@twinsun.com>
20487 * doc/bison.texinfo (Debugging):
20488 Remove YYSTDERR; it's no longer defined or used.
20489 Also, s/cstdio.h/cstdio/.
20491 2002-01-03 Akim Demaille <akim@epita.fr>
20493 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.

20498 tracing code to --trace, wait for a better --trace option, with
20501 2002-01-03 Akim Demaille <akim@epita.fr>
20503 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
20504 The ISO C++ standard is extremely clear about it: stderr is
20505 considered a macro, not a regular symbol (see table 94 `Header
20506 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
20507 Therefore std:: does not apply to it. It still does with fprintf.
20508 Also, s/cstdio.h/cstdio/.
20510 2002-01-03 Akim Demaille <akim@epita.fr>
20512 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
20513 for non system headers.

20518 pure parser and scanner.
20520 * src/parse-skel.y: Request a pure parser, locations, and prefix
20522 (%union): Having several members with the same type does not help
20523 type mismatches, simplify.
20524 (YYPRINT, yyprint): New.
20525 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
20526 (skel_error): this.
20528 * src/scan-skel.l: Adjust to these changes.
20529 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
20530 (LOCATION_PRINT, skel_control_t): New.
20532 2001-12-30 Akim Demaille <akim@epita.fr>
20534 * src/parse-skel.y: Get rid of the shift/reduce conflict:
20535 replace `gb' with BLANKS.
20536 * src/scan-skel.l: Adjust.
20538 2001-12-30 Akim Demaille <akim@epita.fr>
20540 * src/system.h: We don't need nor want bcopy.
20541 Throw away MS-DOS crap: we don't need getpid.
20542 * configure.in: We don't need strndup. It was even causing
20543 problems: because Flex includes the headers *before* us,
20544 _GNU_SOURCE is not defined by config.h, and therefore strndup was
20546 * lib/xstrndup.c: New.
20547 * src/scan-skel.l: Use it.
20548 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
20549 * src/parse-skel.y: Use %directives instead of #defines.
20551 2001-12-30 Akim Demaille <akim@epita.fr>
20553 * src/skeleton.h: New.
20554 * src/output.c (output_parser, output_master_parser): Remove, dead
20556 * src/output.h (get_lines_number, actions_output, guards_output)
20557 (token_definitions_output): Prototype them.
20558 * src/parse-skel.y: Add the license notice.
20559 Include output.h and skeleton.h.
20560 (process_skeleton): Returns void, and takes a single parameter.
20561 * src/scan-skel.l: Add the license notice.
20562 Include skeleton.h.
20563 Don't use %option yylineno: it seems that then Flex imagines
20564 REJECT has been used, and therefore it won't reallocate its
20565 buffers (which makes no other sense to me than a bug). It results
20566 in warnings for `unused: yy_flex_realloc'.
20568 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
20570 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
20571 (MUSCLE_INSERT_PREFIX): ...to there.
20572 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
20573 (MUSCLE_INSERT_PREFIX): Move from here...
20575 * src/bison.hairy: Add a section directive. Put braces around muscle
20576 names. This parser skeleton is still broken, but Bison should not
20577 choke on a bad muscle 'syntax'.
20578 * src/bison.simple: Add a section directive. Put braces around muscle
20581 * src/files.h (strsuffix, stringappend): Add declarations.
20582 (tab_extension): Add declaration.
20583 (short_base_name): Add declaration.
20585 * src/files.c (strsuffix, stringappend): No longer static. These
20586 functions are used in the skeleton parser.
20587 (tab_extension): New.
20588 (compute_base_names): Use the computations done in this function
20589 to guess if the generated parsers should have '.tab' in their
20591 (short_base_name): No longer static.
20593 * src/output.c (output_skeleton): New.
20594 (output): Disable call to output_master_parser, and give a try to
20595 a new skeleton handling system.
20596 (guards_output, actions_output): No longer static.
20597 (token_definitions_output, get_lines_number): No longer static.
20599 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
20601 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
20604 * src/parse-skel.y: New file.
20605 * src/scan-skel.l: New file.
20607 2001-12-29 Akim Demaille <akim@epita.fr>
20609 %name-prefix is broken.
20611 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
20612 Adjust all dependencies.
20613 * tests/headers.at (export YYLTYPE): Strengthen this test: use
20616 Renaming yylval but not yylloc is not consistent. Now we do.
20618 * src/bison.simple: Prefix yylloc if used.
20619 * doc/bison.texinfo (Decl Summary): Document that.
20621 2001-12-29 Akim Demaille <akim@epita.fr>
20623 * doc/bison.texinfo: Promote `%long-directive' over
20625 Remove all references to fixed-output-files, yacc is enough.
20627 2001-12-29 Akim Demaille <akim@epita.fr>
20629 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
20630 user prologue. These are defaults.
20631 * tests/actions.at (Mid-rule actions): Make sure the user can
20632 define YYDEBUG and YYERROR_VERBOSE.
20634 2001-12-29 Akim Demaille <akim@epita.fr>
20636 * src/output.c (header_output): Don't forget to export YYLTYPE and
20638 * tests/headers.at (export YYLTYPE): New, make sure it does.
20639 * tests/regression.at (%union and --defines, Invalid CPP headers):
20641 * tests/headers.at: here.
20643 2001-12-29 Akim Demaille <akim@epita.fr>
20645 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
20647 2001-12-29 Akim Demaille <akim@epita.fr>
20649 * tests/actions.at (Mid-rule actions): Output on a single line
20650 instead of several.
20652 2001-12-29 Akim Demaille <akim@epita.fr>
20654 * doc/bison.texinfo: Formatting changes.
20656 2001-12-29 Akim Demaille <akim@epita.fr>
20658 Don't store the token defs in a muscle, just be ready to output it
20659 on command. Now possible via `symbols'. Fixes a memory leak.
20661 * src/output.c (token_definitions_output): New.
20662 (output_parser, header_output): Use it.
20663 * src/reader.c (symbols_save): Remove.
20665 2001-12-29 Akim Demaille <akim@epita.fr>
20667 * src/bison.simple: Do not provide a default for YYSTYPE and
20668 YYLTYPE before the user's prologue. Otherwise it's hardly... a
20671 2001-12-29 Akim Demaille <akim@epita.fr>
20673 Mid-rule actions are simply... ignored!
20675 * src/reader.c (readgram): Be sure to attach mid-rule actions to
20676 the empty-rule associated to the dummy symbol, not to the host
20678 * tests/actions.at (Mid-rule actions): New.
20680 2001-12-29 Akim Demaille <akim@epita.fr>
20684 * src/reader.c (reader): Free grammar.
20686 2001-12-29 Akim Demaille <akim@epita.fr>
20690 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
20691 since it allocates it for each state, although only one is needed.
20692 (allocate_storage): Do it here.
20694 2001-12-29 Akim Demaille <akim@epita.fr>
20696 * src/options.h, src/options.c (create_long_option_table): Rename
20698 (long_option_table_new): this, with a clearer prototype.
20699 (percent_table): Remove, unused,
20700 * src/getargs.c (getargs): Adjust.
20702 2001-12-29 Akim Demaille <akim@epita.fr>
20704 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
20705 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
20708 2001-12-29 Akim Demaille <akim@epita.fr>
20710 * src/lalr.c (build_relations): Rename `states' as `states1'.
20711 Sorry, I don't understand exactly what it is, no better name...
20713 2001-12-29 Akim Demaille <akim@epita.fr>
20715 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
20716 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
20717 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
20720 2001-12-29 Akim Demaille <akim@epita.fr>

20725 2001-12-29 Akim Demaille <akim@epita.fr>
20727 * src/reader.c, src/reader.h (user_toknums): Remove.
20728 Adjust all users to use symbols[i]->user_token_number.
20730 2001-12-29 Akim Demaille <akim@epita.fr>
20732 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
20733 Adjust all users to use symbols[i]->prec or ->assoc.
20735 2001-12-29 Akim Demaille <akim@epita.fr>
20737 * src/reader.c, src/reader.h (tags): Remove.
20738 Adjust all users to use symbols[i]->tag.
20740 2001-12-29 Akim Demaille <akim@epita.fr>
20742 * src/gram.h, src/gram.c (symbols): New, similar to state_table
20744 * src/reader.c (packsymbols): Fill this table.
20746 * src/conflicts.c (resolve_sr_conflict): Adjust.
20747 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
20749 Use symbols[i]->tag instead of tags[i].
20751 2001-12-29 Akim Demaille <akim@epita.fr>
20753 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
20754 In addition, put a comment in there, to replace...
20755 * tests/regression.at (%union and C comments): Remove.
20757 2001-12-29 Akim Demaille <akim@epita.fr>
20759 * tests/regression.at (Web2c Actions): Blindly move the actual
20760 output as expected output. The contents *seem* right to me, but I
20761 can't pretend reading perfectly parser tables... Nonetheless, all
20762 the other tests pass correctly, the table look OK, even though the
20763 presence of `$axiom' is to be noted: AFAICS it is useless (but
20766 2001-12-29 Akim Demaille <akim@epita.fr>
20768 * src/reader.c (readgram): Don't add the rule 0 if there were no
20769 rules read. In other words, add it _after_ having performed
20770 grammar sanity checks.
20771 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
20773 2001-12-29 Akim Demaille <akim@epita.fr>
20775 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
20776 visible, and some states have now a different number.
20778 2001-12-29 Akim Demaille <akim@epita.fr>
20780 * src/reader.c (readgram): Bind the initial rule's lineno to that
20782 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
20783 (Solved SR Conflicts): Adjust rule 0's line number.
20785 2001-12-29 Akim Demaille <akim@epita.fr>
20787 Fix the `GAWK Grammar' failure.
20789 * src/LR0.c (final_state): Initialize to -1 so that we do compute
20790 the reductions of the first state which was mistakenly confused
20791 with the final state because precisely final_state was initialized
20793 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
20794 now noticed by Bison.
20795 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
20796 have a reduction on $default.
20798 2001-12-29 Akim Demaille <akim@epita.fr>
20800 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
20802 * src/closure.c (print_closure): Likewise.
20803 * src/derives.c (print_derives): Likewise.
20804 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
20807 2001-12-29 Akim Demaille <akim@epita.fr>
20809 * src/lalr.c (lookaheads_print): New.
20810 (lalr): Call it when --trace-flag.
20811 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
20814 2001-12-29 Akim Demaille <akim@epita.fr>
20816 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
20817 when walking through ritem, even via rule->rhs.
20818 * src/reduce.c (dump_grammar, useful_production, reduce_output)
20819 (useful_production, useless_nonterminals): Likewise.
20820 (reduce_grammar_tables): Likewise, plus update nritems.
20821 * src/nullable.c (set_nullable): Likewise.
20822 * src/lalr.c (build_relations): Likewise.
20823 * tests/sets.at (Nullable): Adjust.
20824 Fortunately, now, the $axiom is no longer nullable.
20826 2001-12-29 Akim Demaille <akim@epita.fr>
20828 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

20831 * src/reduce.c (nonterminals_reduce): Likewise.
20832 * src/print_graph.c (print_graph): Likewise.
20833 * src/output.c (output_rule_data): Likewise.
20834 * src/nullable.c (set_nullable): Likewise.
20836 2001-12-29 Akim Demaille <akim@epita.fr>
20838 * src/output.c: Comment changes.
20840 2001-12-27 Paul Eggert <eggert@twinsun.com>
20842 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
20843 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
20844 Sparc, as they were causing more porting problems than the
20845 (minor) performance improvement was worth.
20847 Also, catch up with 1.31's YYSTD.
20849 2001-12-27 Akim Demaille <akim@epita.fr>
20851 * src/output.c (output_gram): Rely on nritems, not the
20852 0-sentinel. See below.
20853 Use -1 as separator, not 0.
20854 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
20855 Rely on -1 as separator in yyrhs, instead of 0.
20856 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
20857 twice `Now at end of input', therefore there are two lines less to
20860 2001-12-27 Akim Demaille <akim@epita.fr>
20862 * tests/regression.at (Unresolved SR Conflicts):
20863 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
20866 2001-12-27 Akim Demaille <akim@epita.fr>
20868 * src/LR0.c (new_state): Recognize the final state by the fact it
20869 is reached by eoftoken.
20870 (insert_start_shifting_state, insert_eof_shifting_state)
20871 (insert_accepting_state, augment_automaton): Remove, since now
20872 these states are automatically computed from the initial state.
20873 (generate_states): Adjust.
20874 * src/print.c: When reporting a rule number to the user, substract
20875 1, so that the axiom rule is rule 0, and the first user rule is 1.
20876 * src/reduce.c: Likewise.
20877 * src/print_graph.c (print_core): For the time being, just as for
20878 the report, depend upon --trace-flags to dump the full set of
20880 * src/reader.c (readgram): Once the grammar read, insert the rule
20881 0: `$axiom: START-SYMBOL $'.
20882 * tests/set.at: Adjust: rule 0 is now displayed, and since the
20883 number of the states has changed (the final state is no longer
20884 necessarily the last), catch up.
20886 2001-12-27 Akim Demaille <akim@epita.fr>
20888 Try to make the use of the eoftoken valid. Given that its value
20889 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
20890 is used instead of > 0 where appropriate, (ii), depend upon nritems
20891 instead of the 0-sentinel.
20893 * src/gram.h, src/gram.c (nritems): New.
20894 Expected to be duplication of nitems, but for the time being...
20895 * src/reader.c (packgram): Assert nritems and nitems are equal.
20896 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
20897 * src/closure.c (print_closure, print_fderives): Likewise.

20902 2001-12-27 Akim Demaille <akim@epita.fr>
20904 * src/main.c (main): If there are complains after grammar
20905 reductions, then output the report anyway if requested, then die.
20906 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
20907 * src/reader.c (eoftoken): New.
20908 (parse_token_decl): If the token being defined has value `0', it
20910 (packsymbols): No longer hack `tags' to insert `$' by hand.
20911 Be sure to preserve the value of the eoftoken.
20912 (reader): Make sure eoftoken is defined.
20913 Initialize nsyms to 0: now eoftoken is created just like the others.
20914 * src/print.c (print_grammar): Don't special case the eof token.
20915 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
20916 lie anyway, albeit pleasant.
20917 * tests/calc.at: Exercise error messages with eoftoken.
20918 Change the grammar so that empty input is invalid.
20919 Adjust expectations.
20920 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
20922 2001-12-27 Akim Demaille <akim@epita.fr>
20924 * configure.in: Check the protos of strchr ans strspn.
20925 Replace strchr if needed.
20926 * src/system.h: Provide the protos of strchr, strspn and memchr if
20928 * lib/strchr.c: New.
20929 * src/reader.c (symbols_save): Use strchr.
20931 2001-12-27 Akim Demaille <akim@epita.fr>
20933 * src/print.c, src/print_graph.c (escape): New.
20934 Use it to quote the TAGS outputs.
20935 * src/print_graph.c (print_state): Now errors are in red, and
20936 reductions in green.
20937 Prefer high to wide: output the state number on a line of its own.
20939 2001-12-27 Akim Demaille <akim@epita.fr>
20941 * src/state.h, src/state.c (reductions_new): New.
20942 * src/LR0.c (set_state_table): Let all the states have a
20943 `reductions', even if reduced to 0.
20944 (save_reductions): Adjust.

20946 * src/print.c (print_reductions, print_actions): Adjust.

20952 * src/LR0.c (set_state_table): Let all the states have an errs,
20953 even if reduced to 0.
20954 * src/print.c (print_errs, print_reductions): Adjust.
20955 * src/output.c (output_actions, action_row): Adjust.

20995 * src/output.c (output): Adjust.
20996 * src/reader.c (parse_braces): New, factoring...
20997 (copy_action, copy_guard): these two which are renamed as...
20998 (parse_action, parse_guard): these.
20999 As a voluntary consequence, using braces around guards is now
21002 2001-12-27 Akim Demaille <akim@epita.fr>
21004 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
21005 * src/reader.c (symbol_list): `guard' and `guard_line' are new
21007 (symbol_list_new): Adjust.
21008 (copy_action): action_line is the first line, not the last.
21009 (copy_guard): Just as for actions, store the `action' only, not
21010 the switch/case/break flesh.
21011 Don't parse the user action that might follow the guard, let...
21012 (readgram): do it, i.e., now, there can be an action after a
21014 In other words the guard is just explicitly optional.
21015 (packgram): Adjust.
21016 * src/output.c (guards_output): New.
21017 (output_parser): Call it when needed.
21018 (output): Also free the guard and attrs obstacks.
21019 * src/files.c, src/files.h (obstack_save): Remove.
21020 (output_files): Remove.
21021 As a result, if one needs the former `.act' file, using an
21022 appropriate skeleton which requires actions and guards is now
21024 * src/main.c (main): Adjust.
21025 * tests/semantic.at: New.
21026 * tests/regression.at: Use `input.y' as input file name.
21027 Avoid 8+3 problems by requiring input.c when the test needs the
21030 2001-12-27 Akim Demaille <akim@epita.fr>
21032 * src/reader.c (symbol_list_new): Be sure to initialize all the
21035 2001-12-27 Akim Demaille <akim@epita.fr>
21037 All the hacks using a final pseudo state are now useless.
21039 * src/LR0.c (set_state_table): state_table holds exactly nstates.
21040 * src/lalr.c (nLA): New.
21041 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
21042 instead of lookaheadsp from the pseudo state (nstate + 1).
21044 2001-12-27 Akim Demaille <akim@epita.fr>
21046 * src/output.c (action_row, token_actions): Use a state_t instead
21047 of a integer, and nlookaheads instead of the following state's
21050 2001-12-27 Akim Demaille <akim@epita.fr>
21052 * src/conflicts.c (log_resolution, flush_shift)
21053 (resolve_sr_conflict, set_conflicts, solve_conflicts)
21054 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
21055 (conflicts_print, print_reductions): Use a state_t instead of an
21056 integer when referring to a state.
21057 As much as possible, depend upon nlookaheads, instead of the
21058 `lookaheadsp' member of the following state (since lookaheads of
21059 successive states are successive, the difference between state n + 1
21060 and n served as the number of lookaheads for state n).
21061 * src/lalr.c (add_lookback_edge): Likewise.
21062 * src/print.c (print_core, print_actions, print_state)
21063 (print_results): Likewise.
21064 * src/print_graph.c (print_core, print_actions, print_state)
21065 (print_graph): Likewise.
21066 * src/conflicts.h: Adjust.
21068 2001-12-27 Akim Demaille <akim@epita.fr>
21070 * src/bison.hairy: Formatting/comment changes.
21072 Remove `register' indications.
21073 Add plenty of `static'.
21075 2001-12-27 Akim Demaille <akim@epita.fr>
21077 * src/output.c (prepare): Drop the muscle `ntbase' which
21078 duplicates ntokens.
21079 * src/bison.simple: Formatting/comment changes.
21080 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
21081 is an undocumented synonym.
21083 2001-12-22 Akim Demaille <akim@epita.fr>
21085 * src/output.c (output_table_data): Change the prototype to use
21086 `int' for array ranges: some invocations do pass an int, not a
21088 Reported by Wayne Green.
21090 2001-12-22 Akim Demaille <akim@epita.fr>
21092 Some actions of web2c.y are improperly triggered.
21093 Reported by Mike Castle.
21095 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
21096 * tests/regression.at (Web2c): Rename as...
21097 (Web2c Report): this.
21098 (Web2c Actions): New.
21100 2001-12-22 Akim Demaille <akim@epita.fr>
21102 Reductions in web2c.y are improperly reported.
21103 Reported by Mike Castle.
21105 * src/conflicts.c (print_reductions): Fix.
21106 * tests/regression.at (Web2c): New.
21108 2001-12-18 Akim Demaille <akim@epita.fr>
21110 Some host fail on `assert (!"foo")', which expands to
21111 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
21112 Reported by Nelson Beebee.
21114 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
21115 `#define it_succeeded 0' and `assert (it_succeeded)'.
21117 2001-12-17 Marc Autret <autret_m@epita.fr>
21119 * src/bison.simple: Don't hard code the skeleton line and filename.
21120 * src/output.c (output_parser): Rename 'line' as 'output_line'.
21121 New line counter 'skeleton_line' (skeleton-line muscle).
21123 2001-12-17 Paul Eggert <eggert@twinsun.com>
21125 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
21126 YYDEBUG must be defined to a nonzero value.
21128 * src/bison.simple (yytname): Do not assume that the user defines
21129 YYDEBUG to a properly parenthesized expression.
21131 2001-12-17 Akim Demaille <akim@epita.fr>
21133 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
21134 nlookaheads is a new member.
21136 * src/lalr.h (nlookaheads): Remove this orphan declaration.
21137 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
21140 2001-12-17 Akim Demaille <akim@epita.fr>
21142 * src/files.h, src/files.c (open_files, close_files): Remove.
21143 * src/main.c (main): Don't open/close files, nor invoke lex_free,
21145 * src/reader.c (reader): Do it.
21147 2001-12-17 Akim Demaille <akim@epita.fr>
21149 * src/conflicts.c (print_reductions): Formatting changes.
21151 2001-12-17 Akim Demaille <akim@epita.fr>
21153 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
21154 (flush_reduce): New.
21155 (resolve_sr_conflict): Adjust.
21157 2001-12-17 Akim Demaille <akim@epita.fr>
21159 * src/output.c (output_obstack): Be static and rename as...
21160 (format_obstack): this, to avoid any confusion with files.c's
21162 * src/reader.h (muscle_obstack): Move to...
21163 * src/output.h: here, since it's defined in output.c.
21165 2001-12-17 Akim Demaille <akim@epita.fr>
21167 * src/output.c (action_row, save_column, default_goto)
21168 (sort_actions, matching_state, pack_vector): Better variable
21171 2001-12-17 Akim Demaille <akim@epita.fr>
21173 * src/output.c: Various formatting changes.
21175 2001-12-17 Akim Demaille <akim@epita.fr>
21177 * src/files.c (output_files): Free the output_obstack.
21178 * src/main.c (main): Call print and print_graph conditionally.
21179 * src/print.c (print): Work unconditionally.
21180 * src/print_graph.c (print_graph): Work unconditionally.
21181 * src/conflicts.c (log_resolution): Output only if verbose_flag.
21183 2001-12-16 Marc Autret <autret_m@epita.fr>
21185 * src/output.c (actions_output): Fix. When we use %no-lines,
21186 there is one less line per action.
21188 2001-12-16 Marc Autret <autret_m@epita.fr>
21190 * src/bison.simple: Remove a useless #line directive.
21191 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
21192 * src/output.c (get_lines_number): New.
21193 (output_parser): Adjust, now takes care about the lines of a
21195 Fix line numbering.
21196 (actions_output): Computes the number of lines taken by actions.
21197 (output_master_parser): Insert new skeleton which is the name of
21198 the output parser file name.
21200 2001-12-15 Marc Autret <autret_m@epita.fr>
21202 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
21204 2001-12-15 Marc Autret <autret_m@epita.fr>
21206 * src/output.c (output_gram): Keep track of the hairy one.
21208 2001-12-15 Akim Demaille <akim@epita.fr>
21210 Make `make distcheck' work.
21212 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
21213 system.h which uses libgettext.h.
21215 2001-12-15 Akim Demaille <akim@epita.fr>
21217 * src/nullable.c (set_nullable): Useless rules must be skipped,
21218 otherwise, since we range over their symbols, we might look at a
21219 nonterminal which no longer ``exists'', i.e., it is not counted in
21220 `nvars', hence we overflow our arrays.
21222 2001-12-15 Akim Demaille <akim@epita.fr>
21224 The header can also be produced directly, without any obstack!
21227 * src/files.c, src/files.h (defines_obstack): Remove.
21228 (compute_header_macro): Global.
21229 (defines_obstack_save): Remove.
21230 * src/reader.c (parse_union_decl): No longer output to
21231 defines_obstack: its content can be found in the `stype' muscle
21233 (output_token_translations): Merge into...
21234 (symbols_output): this.
21236 (symbols_save): this.
21238 * src/output.c (header_output): New.
21241 2001-12-15 Akim Demaille <akim@epita.fr>
21243 * src/reader.c (parse_union_decl): Instead of handling two obstack
21244 simultaneously, use one to define the `stype' muscle, and use the
21245 value of the latter to fill defines_obstack.
21246 (copy_comment): Remove.
21247 (copy_comment2): Work for a single obstack.
21249 (copy_comment): this.
21251 2001-12-15 Akim Demaille <akim@epita.fr>
21253 * src/lex.c, src/lex.h (xgetc): No longer static.
21254 * src/reader.c (parse_union_decl): Revamp.
21256 2001-12-15 Akim Demaille <akim@epita.fr>
21258 Still making progress in separating Bison into (i) input, (ii)
21259 process, (iii) output: now we can directly output the parser file
21260 without using table_obstack at all.
21262 * src/files.c, src/files.h (table_obstack): Bye bye.
21263 (parser_file_name): New.
21264 * src/files.c (compute_output_file_names): Compute it.
21265 * src/output.c (actions_output, output_parser)
21266 (output_master_parser): To a file instead of an obstack.
21268 2001-12-15 Akim Demaille <akim@epita.fr>
21270 Attach actions to rules, instead of pre-outputting them to
21273 * src/gram.h (rule_t): action and action_line are new members.
21274 * src/reader.c (symbol_list): Likewise.
21275 (copy_action): Save the actions within the rule.
21276 (packgram): Save them in rule_table.
21277 * src/output.c (actions_output): New.
21278 (output_parser): Use it on `%%actions'.
21279 (output_rule_data): Don't free rule_table.
21281 (prepare): Don't save the `action' muscle.
21282 * src/bison.simple: s/%%action/%%actions/.
21284 2001-12-15 Akim Demaille <akim@epita.fr>
21286 * src/reader.c (copy_action): When --yacc, don't append a `;'
21287 to the user action: let it fail if lacking.
21288 Suggested by Arnold Robbins and Tom Tromey.
21290 2001-12-14 Akim Demaille <akim@epita.fr>
21292 * src/lex.c (literalchar): Simply return the char you decoded, non
21293 longer mess around with obstacks and int pointers.
21294 Adjust all callers.
21296 2001-12-14 Akim Demaille <akim@epita.fr>
21298 * src/lex.c (literalchar): Don't escape the special characters,
21299 just decode them, and keep them as char (before, eol was output as
21300 the 2 char string `\n' etc.).
21301 * src/output.c (output_rule_data): Use quotearg to output the
21304 2001-12-13 Paul Eggert <eggert@twinsun.com>
21306 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
21307 Do not infringe on the global user namespace when using C++.
21308 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
21309 All uses of `fprintf' and `stderr' changed.
21311 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
21313 2001-12-13 Akim Demaille <akim@epita.fr>
21315 The computation of nullable is broken: it doesn't handle empty
21318 * tests/torture.at (GNU AWK Grammar): New.
21319 * tests/sets.at (Nullable): New.
21320 * src/nullable.c (set_nullable): Instead of blindly looping over
21321 `ritems', loop over the rules, and then over their rhs's.
21323 Work around Autotest bugs.
21325 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
21326 frame, because Autotest understand lines starting with a `+' as
21327 traces from the shell. Then, they are not processed properly.
21328 Admittedly an Autotest bug, but we don't have time to wait for
21329 Autotest to catch up.
21330 * tests/regression.at (Broken Closure): Adjust to the new table
21333 * tests/sets.at: here.
21335 2001-12-13 Akim Demaille <akim@epita.fr>
21337 * src/closure.c (closure): Use nrules instead of playing tricks
21338 with BITS_PER_WORD.
21340 2001-12-13 Akim Demaille <akim@epita.fr>
21342 * src/print.c (print_actions): Output the handling of `$' as the
21343 traces do: shifting the token EOF. Before EOF was treated as a
21345 * tests/regression.at: Adjust some tests.
21346 * src/print_graph.c (print_core): Complete the set of items via
21347 closure. The next-to-final and final states are still unsatisfying,
21348 but that's to be addressed elsewhere.
21349 No longer output the rule numbers, but do output the state number.
21350 A single loop for the shifts + gotos is enough, but picked a
21351 distinct color for each.
21352 (print_graph): Initialize and finalize closure.
21354 2001-12-13 Akim Demaille <akim@epita.fr>
21356 * src/reader.c (readgram): Remove dead code, an strip useless
21358 (get_type): Remove, unused.
21360 2001-12-12 Akim Demaille <akim@epita.fr>
21362 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
21363 on that of lib/error.c.
21365 2001-12-12 Akim Demaille <akim@epita.fr>
21367 Some hosts don't like `/' in includes.
21369 * src/system.h: Include libgettext.h without qualifying the path.
21370 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
21373 2001-12-11 Marc Autret <autret_m@epita.fr>
21375 * src/output.c (output_parser): Remove useless muscle.
21377 2001-12-11 Marc Autret <autret_m@epita.fr>
21379 * src/bison.simple: Remove #line just before %%epilogue. It
21380 is now handled in ...
21381 * src/reader.c (read_additionnal_code): Add the output of a
21382 #line for the epilogue.
21384 2001-12-10 Marc Autret <autret_m@epita.fr>
21386 * src/reader.c (copy_definition): Re-use CPP-outed code which
21387 replace precedent remove.
21388 * src/bison.simple: Remove #line before %%prologue because
21389 %%input-line is wrong at this time.
21391 2001-12-10 Marc Autret <autret_m@epita.fr>
21393 * src/reader.c (symbols_output): Clean up.
21394 * src/output.c (output_gram, output): Clean up.
21396 2001-12-10 Akim Demaille <akim@epita.fr>
21398 * src/lalr.c (initialize_lookaheads): New. Extracted from...
21399 * src/LR0.c (set_state_table): here.
21400 * src/lalr.c (lalr): Call it.
21402 2001-12-10 Akim Demaille <akim@epita.fr>
21404 * src/state.h (shifts): Remove the `number' member: shifts are
21405 attached to state, hence no longer need to be labelled with a
21408 2001-12-10 Akim Demaille <akim@epita.fr>
21410 Now that states have a complete set of members, the linked list of
21411 shifts is useless: just fill directly the state's shifts member.
21413 * src/state.h (shifts): Remove the `next' member.
21414 * src/LR0.c (first_state, last_state): Remove.
21415 Adjust the callers.
21416 (augment_automaton): Don't look for the shifts that must be added
21417 a shift on EOF: it is those of the state we looked for! But now,
21418 since shifts are attached, it is no longer needed to looking
21419 merely by its id: its number.
21421 2001-12-10 Akim Demaille <akim@epita.fr>
21423 * src/LR0.c (augment_automaton): Better variable locality.
21424 Remove an impossible branch: if there is a state corresponding to
21425 the start symbol being shifted, then there is shift for the start
21426 symbol from the initial state.
21428 2001-12-10 Akim Demaille <akim@epita.fr>
21430 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
21431 only when appropriate: when insert_start_shifting_state' is not
21433 * tests/regression.at (Rule Line Numbers): Adjust.
21435 2001-12-10 Akim Demaille <akim@epita.fr>
21437 * src/LR0.c (augment_automaton): Now that all states have shifts,
21438 merge the two cases addition shifts to the initial state.
21440 2001-12-10 Akim Demaille <akim@epita.fr>
21442 * src/lalr.c (set_state_table): Move to...
21444 * src/lalr.c (lalr): Don't call it...
21445 * src/LR0.c (generate_states): do it.
21446 * src/LR0.h (first_state): Remove, only the table is used.
21448 2001-12-10 Akim Demaille <akim@epita.fr>
21450 * src/LR0.h (first_shift, first_reduction): Remove.
21451 * src/lalr.c: Don't use first_shift: find shifts through the
21454 2001-12-10 Akim Demaille <akim@epita.fr>
21456 * src/LR0.c: Attach shifts to states as soon as they are
21458 * src/lalr.c (set_state_table): Instead of assigning shifts to
21459 state, just assert that the mapping was properly done.
21461 2001-12-10 Akim Demaille <akim@epita.fr>
21463 * src/LR0.c (insert_start_shift): Rename as...
21464 (insert_start_shifting_state): this.
21465 (insert_eof_shifting_state, insert_accepting_state): New.
21466 (augment_automaton): Adjust.
21467 Better locality of the variables.
21468 When looking if the start_symbol is shifted from the initial
21469 state, using `while (... symbol != start_symbol ...)' sounds
21470 better than `while (... symbol < start_symbol ...)': If fail
21471 to see how the order between symbols could be relevant!
21473 2001-12-10 Akim Demaille <akim@epita.fr>
21475 * src/getargs.h: Don't declare `spec_name_prefix' and
21476 `spec_file_prefix', declared by src/files.h.
21477 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
21478 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
21479 * src/output.c (prepare): Adjust.
21480 * src/reader.c (symbols_output): Likewise.
21481 * src/vmsgetargs.c: Vaguely adjust, but who cares?
21483 2001-12-10 Akim Demaille <akim@epita.fr>
21485 * src/muscle_tab.c (muscle_init): NULL is a better default than
21488 2001-12-10 Akim Demaille <akim@epita.fr>
21490 * src/reader.c (reader): Calling symbols_output once is enough.
21492 2001-12-10 Akim Demaille <akim@epita.fr>
21494 Now that states have a complete set of members, the linked list of
21495 reductions is useless: just fill directly the state's reductions
21498 * src/state.h (struct reductions): Remove member `number' and
21500 * src/LR0.c (first_reduction, last_reduction): Remove.
21501 (save_reductions): Don't link the new reductions, store them in
21503 * src/lalr.c (set_state_table): No need to attach reductions to
21504 states, it's already done.
21505 * src/output.c (output_actions): No longer free the shifts, then
21506 the reductions, then the states: free all the states and their
21509 2001-12-10 Akim Demaille <akim@epita.fr>
21511 * src/options.c (OPTN, DRTV, BOTH): New.
21512 (option_table): Use them.
21514 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
21515 the job of system.h.
21516 * src/options.c: Don't include stdio.h and xalloc.h for the same
21519 2001-12-10 Akim Demaille <akim@epita.fr>
21521 * src/output.c (output, prepare): Make sure the values of the
21522 muscles `action' and `prologue' are 0-terminated.
21524 2001-12-10 Akim Demaille <akim@epita.fr>
21526 Clean up GCC warnings.
21528 * src/reader.c (copy_action): `buf' is not used.
21529 (parse_skel_decl): Be static.
21530 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
21531 * src/options.h (create_long_option_table): Have a real prototype.
21532 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
21533 (hash_delete_at): Return const void *.
21534 Adjust casts to preserve the const.

21541 * tests/Makefile.am: Adjust.
21543 2001-12-10 Akim Demaille <akim@epita.fr>
21545 One structure for states is enough, even though theoretically
21546 there are LR(0) states and LALR(1) states.
21548 * src/lalr.h (state_t): Remove.
21549 (state_table): Be state_t **, not state_t *.
21550 * src/state.h (core, CORE_ALLOC): Rename as...
21551 (state_t, STATE_ALLOC): this.
21552 Add the LALR(1) members: shifts, reductions, errs.
21553 * src/LR0.c (state_table): Rename as...
21554 (state_hash): this, to avoid name clashes with the global
21556 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
21557 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
21559 2001-12-10 Akim Demaille <akim@epita.fr>
21561 Bison dumps core on bash.y.
21562 Reported by Pascal Bart.
21564 * src/warshall.c (bitmatrix_print): New.
21566 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
21567 j must be the outer loop.
21568 * tests/regression.at (Broken Closure): New.
21570 2001-12-05 Akim Demaille <akim@epita.fr>
21572 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
21574 Reported by Peter Hamorsky.

21579 (resolve_sr_conflict): Adjust.
21580 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
21582 (state_t.reductions, state_t.shifts): this.
21584 2001-12-05 Akim Demaille <akim@epita.fr>
21586 * src/reduce.c (reduce_grammar_tables): No longer disable the
21587 removal of useless rules via CPP but via `if (0)', so that the
21588 compiler still check the code is valid.
21589 For instance, it should have noticed `rline' no longer exists: use
21590 the `line' member of rule_t.
21591 * src/gram.c (dummy, rline): Remove, unused.
21593 2001-12-05 Akim Demaille <akim@epita.fr>
21595 * src/output.c (pack_vector): Use assert, not berror.
21596 * src/main.c (berror): Remove, unused.
21598 2001-12-05 Akim Demaille <akim@epita.fr>
21600 New experimental feature: if --verbose --trace output all the
21601 items of a state, not only its kernel.
21603 * src/print.c (print_core): If `trace_flag', then invoke closure
21604 before outputting the items of the state (print_core is no longer
21605 a correct name them).
21606 (print_results): Invoke new_closure/free_closure if needed.
21608 2001-12-05 Akim Demaille <akim@epita.fr>
21610 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
21611 * src/closure.c, src/closure.h (itemsetsize): Rename as...
21612 (nitemset): for consistency with the rest of the project.

21616 * src/closure.c (print_closure): Improve.
21617 (closure): Use it for printing input and output.
21619 2001-12-05 Akim Demaille <akim@epita.fr>

21622 indexed by nonterminals.
21624 2001-12-05 Akim Demaille <akim@epita.fr>
21626 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

21642 2001-12-05 Akim Demaille <akim@epita.fr>
21644 * src/output.c (action_row): De-obfuscate
21645 using the good o' techniques: arrays not pointers, variable
21646 locality, BITISSET, RESETBIT etc.
21648 2001-12-05 Akim Demaille <akim@epita.fr>
21650 Pessimize the code to simplify it: from now on, all the states
21651 have a valid SHIFTS, which NSHIFTS is possibly 0.
21653 * src/LR0.c (shifts_new): Be global and move to..
21654 * src/state.c, src/state.h: here.
21655 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
21656 * src/print_graph: Adjust.
21658 2001-12-05 Akim Demaille <akim@epita.fr>
21660 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
21661 * src/conflicts.c: Use it.
21662 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
21663 incorrectly ``simplified''.
21665 2001-12-05 Akim Demaille <akim@epita.fr>
21667 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
21668 using the good o' techniques: arrays not pointers, variable
21669 locality, BITISSET, RESETBIT etc.
21671 2001-12-05 Akim Demaille <akim@epita.fr>
21673 * src/state.h (SHIFT_SYMBOL): New.
21674 * src/conflicts.c: Use it to deobfuscate.

21703 2001-12-05 Akim Demaille <akim@epita.fr>
21705 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
21706 * src/lalr.c: Use them.
21708 2001-12-05 Akim Demaille <akim@epita.fr>
21710 * src/LR0.c (augment_automaton): Formatting changes.
21711 Better variable locality.

21721 * src/lalr.c (maxrhs): Move to...
21722 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
21723 * src/lalr.c (build_relations): Adjust.
21725 2001-12-05 Akim Demaille <akim@epita.fr>
21727 * src/lalr.c (transpose): Free the memory allocated to the
21728 argument, as it is replaced by the results by the unique caller.
21729 (build_relations): Merely invoke transpose: it handles the memory
21731 Improve variable locality.
21732 Avoid variables used as mere abbreviations.
21733 (compute_lookaheads): Use arrays instead of pointers.
21735 2001-12-05 Akim Demaille <akim@epita.fr>
21737 * src/lalr.c (initialize_F): Improve variable locality.
21738 Avoid variables used as mere abbreviations.
21740 2001-12-05 Akim Demaille <akim@epita.fr>
21742 * src/derives.c (print_derives): Display the ruleno.
21743 * src/lalr.c (initialize_F, transpose): Better variable locality

21751 2001-12-05 Akim Demaille <akim@epita.fr>
21753 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
21754 the handling of squeue.
21755 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
21757 2001-12-05 Akim Demaille <akim@epita.fr>
21759 Because useless nonterminals are now kept alive (instead of being
21760 `destroyed'), we now sometimes examine them, and store information
21761 related to them. Hence we need to know their number, and adjust
21762 memory allocations.
21764 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
21766 * src/LR0.c (allocate_itemsets): The memory allocated to
21767 `symbol_count' was used for two different purpose: once to count
21768 the number of occurrences of each symbol, and later reassigned to
21769 `shift_symbol', containing the symbol that can be shifted from a
21771 Deobfuscate, i.e., allocate, use and free `symbol_count' here
21773 (new_itemsets): Allocate `shift_symbol' here.
21774 (allocate_itemsets): symbol_count includes useless nonterminals.
21775 Make room for them.
21776 (free_storage): Use `free', not `XFREE', for pointers that cannot
21779 2001-12-05 Akim Demaille <akim@epita.fr>
21781 * src/nullable.c (set_nullable): Deobfuscate the handling of
21783 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
21785 2001-12-05 Akim Demaille <akim@epita.fr>
21787 * src/gram.c, src/gram.h (ritem_print): New.
21788 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
21789 (This useless function was defined only to work around VMS linkers
21790 that can't handle compilation units with variables only).
21791 * src/reduce.c (dump_grammar): Use it to trace the construction of
21794 2001-12-04 Paul Eggert <eggert@twinsun.com>
21796 * src/bison.simple (union yyalloc): Change member names
21797 to be the same as the stack names.
21798 (yyparse): yyptr is now union yyalloc *, not char *.
21799 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
21800 and may generate better code on some machines.
21801 (yystpcpy): Use prototype if __STDC__ is defined, not just
21802 if __cplusplus is defined.
21804 2001-11-30 Akim Demaille <akim@epita.fr>
21806 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
21807 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
21808 Gettext doesn't compile cleanly, and dies with -Werror.
21809 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
21810 Include WARNING_CFLAGS here.
21811 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
21812 before being defined.
21814 2001-11-27 Paul Eggert <eggert@twinsun.com>
21816 * lib/quotearg.h (quotearg_n, quotearg_n_style):
21817 First arg is int, not unsigned.
21818 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
21819 (SIZE_MAX, UINT_MAX): New macros.
21820 (quotearg_n_options): Abort if N is negative.
21821 Avoid overflow check on hosts where size_t is 64 bits and int
21822 is 32 bits, as overflow is impossible there.
21823 Fix off-by-one typo that caused unnecessary reallocation.
21825 2001-11-29 Paul Eggert <eggert@twinsun.com>
21827 Name space cleanup in generated parser.
21829 * doc/bison.texinfo (Bison Parser): Discuss system headers
21830 and their effect on the user name space.
21832 * src/bison.simple:
21833 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
21834 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
21835 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
21837 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
21838 on user names when possible.
21840 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
21841 Simplify test for whather <alloca.h> exists.
21843 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
21845 (<stdio.h>): Include if YYDEBUG.
21847 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
21848 ! defined (yyoverflow) && ! defined (yymemcpy).
21850 (yymemcpy, yyparse): Rename local variables as needed so that
21851 they all begin with 'yy'.
21853 (yystrlen, yystpcpy): New functions.
21855 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
21858 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
21859 instead of relying on string.h functions. Use YYSTACK_ALLOC
21860 and YYSTACK_FREE instead of malloc and free.
21862 2001-11-30 Akim Demaille <akim@epita.fr>
21864 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
21865 before their first uses.

21868 2001-11-30 Akim Demaille <akim@epita.fr>
21870 * tests/reduce.at (Useless Nonterminals): Fix.
21872 2001-11-30 Akim Demaille <akim@epita.fr>
21874 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
21875 if body instead of `;' to pacify GCC's warnings.
21877 2001-11-30 Akim Demaille <akim@epita.fr>
21879 Instead of mapping the LHS of unused rules to -1, keep the LHS
21880 valid, but flag the rules as invalid.
21882 * src/gram.h (rule_t): `useful' is a new member.
21883 * src/print.c (print_grammar): Adjust.
21884 * src/derives.c (set_derives): Likewise.
21885 * src/reader.c (packgram, reduce_output): Likewise.
21886 * src/reduce.c (reduce_grammar_tables): Likewise.
21887 * tests/reduce.at (Underivable Rules, Useless Rules): New.
21889 2001-11-30 Akim Demaille <akim@epita.fr>

21896 2001-11-30 Akim Demaille <akim@epita.fr>
21898 * src/reduce.c (nonterminals_reduce): Instead of throwing away
21899 useless nonterminals, move them at the end of the symbol arrays.
21900 (reduce_output): Adjust.
21901 * tests/reduce.at (Useless Nonterminals): Adjust.
21903 2001-11-30 Akim Demaille <akim@epita.fr>

21913 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
21914 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
21916 (union yyalloc): New type.
21917 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
21918 an arbitrary restriction on hosts where size_t is wider than int.
21920 (yyparse): Don't dump core if alloca or malloc fails; instead, report
21921 a parser stack overflow. Allocate just one block of memory for all
21922 three stacks, instead of allocating three blocks; this typically is
21923 faster and reduces fragmentation.
21925 Do not limit the number of items in the stack to a value that fits
21926 in 'int', as this is an arbitrary limit on hosts with 64-bit
21927 size_t and 32-bit int.
21929 2001-11-29 Marc Autret <autret_m@epita.fr>
21931 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
21932 of defining YYERROR_VERBOSE.

21977 2001-11-28 Akim Demaille <akim@epita.fr>
21979 * src/closure.c (closure): `b' and `ruleno' denote the same value:
21982 2001-11-28 Akim Demaille <akim@epita.fr>
21984 * src/closure.c (closure): Instead of looping over word in array
21985 then bits in words, loop over bits in array.
21987 2001-11-28 Akim Demaille <akim@epita.fr>
21989 * src/closure.c (closure): No longer optimize the special case
21990 where all the bits of `ruleset[r]' are set to 0, to make the code
21993 2001-11-28 Akim Demaille <akim@epita.fr>
21995 * src/closure.c (closure): `r' and `c' are new variables, used to
21996 de-obfuscate accesses to RULESET and CORE.
21998 2001-11-28 Akim Demaille <akim@epita.fr>
22000 * src/reduce.c (reduce_print): Use ngettext.

22009 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
22010 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
22011 as all tags are free'ed afterwards.
22012 From Enrico Scholz.
22014 2001-11-27 Paul Eggert <eggert@twinsun.com>
22016 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
22017 use alloca when we didn't want to, and vice versa.
22019 2001-11-27 Marc Autret <autret_m@epita.fr>
22021 * src/muscle_tab.c (muscle_init): Remove 'verbose' muscle

22360 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

23738 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
23739 New, from fileutils 4.0.37.
23740 * configure.in: Require Autoconf 2.49c. I took some time before

23763 * src/lex.h: Rename all the tokens:
23764 s/\bENDFILE\b/tok_eof/g;
23765 s/\bIDENTIFIER\b/tok_identifier/g;
23767 Let them be enums, not #define, to ease debugging.

23791 introduces a guaranteed SEGV for semantic parsers.
23792 * doc/bison.texinfo: Document them.
23793 * tests/suite.at: Exercise these %options.
23795 2000-12-20 Akim Demaille <akim@epita.fr>

24015 it no longer has to remove tmp files, just call `output_files'
24016 when there are no errors.

24116 2000-10-04 Akim Demaille <akim@epita.fr>
24118 * doc/bison.texinfo: Various typos spotted by Neil Booth.
24120 2000-10-04 Akim Demaille <akim@epita.fr>
24122 When a literal string is used to define two different tokens,
24123 `bison -v' segfaults.
24124 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
24126 * tests/regression.m4: New file.
24127 Include the core of the sample provided by Piotr Gackiewicz.
24128 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
24131 2000-10-04 Akim Demaille <akim@epita.fr>
24133 * src/reader.c (parse_expect_decl): Keep `count' within the size
24137 2000-10-02 Paul Eggert <eggert@twinsun.com>
24139 * bison.s1 (yyparse): Assign the default value
24140 unconditionally, to avoid a GCC warning and make the parser a
24143 2000-10-02 Akim Demaille <akim@epita.fr>
24145 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
24148 2000-10-02 Akim Demaille <akim@epita.fr>
24150 * src/derives.c, src/print.c, src/reduce.c: To ease the
24151 translation, move some `\n' out of the translated strings.
24153 2000-10-02 Akim Demaille <akim@epita.fr>
24155 The location tracking mechanism is precious for parse error
24156 messages. Nevertheless, it is enabled only when `@n' is used in
24157 the grammar, which is a different issue (you can use it in error
24158 message, but not in the grammar per se). Therefore, there should
24159 be another means to enable it.
24161 * src/getargs.c (getargs): Support `--locations'.
24162 (usage): Report it.
24163 * src/getargs.h (locationsflag): Export it.
24164 * src/lex.c (percent_table): Support `%locations'.
24165 * src/reader.c (yylsp_needed): Remove this variable, now replaced
24166 with `locationsflag'.
24167 * doc/bison.texinfo: Document `--locations' and `%locations'.
24169 * tests/calc.m4: Test it.
24171 For regularity of the names, replace each
24172 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
24173 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
24174 In addition replace each `flag' with `_flag'.
24176 2000-10-02 Akim Demaille <akim@epita.fr>
24178 Also test parse error messages, including with YYERROR_VERBOSE.
24180 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
24182 Use it to check the computations.
24183 Use it to check `nonassoc' is honored.
24184 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
24185 `--yyerror-verbose'.
24186 (_AT_CHECK_CALC): Adjust to this option.
24187 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
24189 2000-10-02 Akim Demaille <akim@epita.fr>
24191 Test also `--verbose', `--defines' and `--name-prefix'. Testing
24192 the latter demonstrates a flaw in the handling of non debugging
24193 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
24194 was used in order to simplify:
24210 unfortunately this leads to a CPP conflict when
24211 `--name-prefix=foo' is used since it produces `#define yydebug
24214 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
24215 (YYDPRINTF): New macro.
24217 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
24219 Also test `--verbose', `--defines' and `--name-prefix'.

24223 Improve the readability of the produced parsers.
24225 * src/bison.s1: Formatting changes.
24226 Improve the comment related to the `$' mark.
24227 (yydefault): Don't fall through to `yyresume': `goto' there.
24228 * src/output.c (output_parser): When the `$' is met, skip the end
24230 New variable, `number_of_dollar_signs', to check there's exactly
24231 one `$' in the parser skeleton.
24233 2000-10-02 Akim Demaille <akim@epita.fr>
24235 * lib/xstrdup.c: New file, from the fileutils.
24236 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
24237 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
24238 instead of strlen + xmalloc + strcpy.
24239 * src/symtab.c (copys): Remove, use xstrdup instead.
24241 2000-10-02 Akim Demaille <akim@epita.fr>
24243 * src/gram.h (associativity): New enum type which replaces the
24244 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
24245 `right_assoc', `left_assoc' and `non_assoc'.
24246 Adjust all dependencies.
24247 * src/reader.c: Formatting changes.
24248 (LTYPESTR): Don't define it, use it as a literal in
24249 `reader_output_yylsp'.
24250 * src/symtab.h (symbol_class): New enum type which replaces the
24251 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
24252 `sunknown', `stoken and `snterm'.
24254 2000-10-02 Akim Demaille <akim@epita.fr>
24256 * src/getargs.c (fixed_outfiles): Rename as...
24257 (yaccflag): for consistency and accuracy.
24258 Adjust dependencies.
24260 2000-10-02 Akim Demaille <akim@epita.fr>
24262 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
24263 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
24264 difficult and introduced a lot of core dump. It turns out that
24265 Bison used an implementation of `xmalloc' based on `calloc', and
24266 at various places it does depend upon the initialization to 0. I
24267 have not tried to isolate the pertinent places, and all the former
24268 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
24269 someone should address this issue.
24271 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
24272 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

24282 * src/system.h: Include `assert.h'.
24284 2000-10-02 Akim Demaille <akim@epita.fr>
24286 * src/state.h (nstates, final_state, first_state, first_shift)

24289 Adjust dependencies.
24290 * src/getargs.c (statisticsflag): New variable.
24291 Add support for `--statistics'.

24298 * src/LR0.h: New file.
24301 2000-10-02 Akim Demaille <akim@epita.fr>

24328 Propagate its inclusion.
24329 * src/reduce.c: Topological sort and other formatting changes.
24330 (bool, TRUE, FALSE): Move their definition to...
24331 * src/system.h: here.
24333 2000-10-02 Akim Demaille <akim@epita.fr>
24335 * src/files.c: Formatting changes.
24336 (tryopen, tryclose, openfiles): Rename as...

24366 * src/output.c (token_actions): Introduce a temporary array,
24367 YYDEFACT, that makes it possible for this function to use
24368 output_short_table.
24370 2000-10-02 Akim Demaille <akim@epita.fr>
24372 `user_toknums' is output as a `short[]' in `output.c', while it is
24373 defined as a `int[]' in `reader.c'. For consistency with the
24374 other output tables, `user_toknums' is now defined as a table of

24418 * src/system.h: Define PARAMS.

25351 * src/reader.c (reader_output_yylsp):
25353 (readgram): Use `#if 0' around code that accepted %command
25354 inside grammar rules: The documentation doesn't allow it,
25355 and it will fail since the %command processors scan for the next %.
25356 (parse_token_decl): Extended the %token
25357 declaration to allow a multi-character symbol as an alias.
25358 (parse_thong_decl): New function.
25359 (read_declarations): Added %thong declarations.
25360 (read_declarations): Handle NOOP to deal with allowing
25361 % declarations as another means to specify the flags.
25362 (readgram): Allow %prec prior to semantics embedded in a rule.
25363 (skip_to_char, read_declarations, copy_definition)

25365 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
25366 (get_type_name, copy_guard, copy_action, readgram)
25367 (get_type, packsymbols): Revised most error messages.
25368 Changed `fatal' to `warnxxx' to avoid aborting for error.
25369 Revised and use multiple warnxxx functions to avoid using VARARGS1.
25370 (read_declarations): Improve the error message for
25371 an invalid character. Do not abort.
25372 (read_declarations, copy_guard, copy_action): Use
25373 printable_version to avoid unprintable characters in printed output.
25374 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
25375 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
25376 Allow the type of a non-terminal can be given
25377 more than once, as long as all specifications give the same type.
25380 (output_headers, output_trailers, output, output_gram)
25381 (output_rule_data): Implement noparserflag variable.
25382 Implement toknumflag variable.
25383 (output): Call reader_output_yylsp to output LTYPESTR.
25385 * src/main.c (main):
25386 If reader sees an error, don't process the grammar.
25387 (fatals): Updated to not use VARARGS1.
25388 (printable_version, int_to_string, warn, warni, warns, warnss)
25389 (warnsss): New error reporting functions. Avoid abort for error.

25397 (safegetc): New function to deal with EOF gracefully.
25398 (literalchar); new function to deal with reading \ escapes.
25399 (lex): Use literalchar.
25400 (lex): Implemented "..." tokens.
25401 (literalchar, lex, parse_percent_token): Made tokenbuffer
25402 always contain the token. This includes growing the token
25403 buffer while reading an integer.
25404 (parse_percent_token): Replaced if-else statement with percent_table.
25405 (parse_percent_token): Added % declarations as another
25406 way to specify the flags -n, -l, and -r. Also added hooks for
25407 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
25408 major changes to files.c.
25409 (lex) Retain in the incoming stream a character following
25411 (skip_white_space, lex): Revised most error messages
25412 and changed fatal to warn to avoid aborting.
25413 (percent_table): Added %thong declarations.
25415 * src/gram.h: Comment changes.
25417 * src/files.c (openfiles, open_extra_files, done):
