169 but, in general, we still can't be sure of our next release name.
170 * bootstrap: Add a quick hack to remove from .gitignore the
171 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

299 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
300 ("Output file name: ("): Uncomment test.

322 * bootstrap: Update gnulib CVS repository URL.
323 (symlink_to_dir): Encapsulate the code that guarantees the destination
324 directory exists into...
325 (check_dst_dir): ... this new function, and...
326 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
327 fail when copying files into lib/uniwidth/.
328 * src/output.c (prepare_symbols): When writing yytname muscles, where
329 symbol names will be encoded in C-string literals, tell quotearg to
330 escape trigraphs. This used to be the default in gnulib.
331 * tests/regression.at (Token definitions): Because of the change in
332 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
333 escapes trigraphs in symbol names. Thus, yytname no longer has
334 trigraphs unnecessarily doubly escaped. Update test case output.
335 Extend test case to be sure Bison's own error messages will no longer
336 have trigraphs in symbol names unnecessarily escaped once.

352 consistency. Update the -g and -x entries now that they take
353 arguments. Use brackets to indicate optional arguments.
354 * src/getargs.c (usage): Explain the relationship between arguments of
355 long and short options more completely. Document --defines and -d
356 separately since the former takes an argument but, for POSIX Yacc, the
358 (short_options): Let -W take an optional argument like --warnings.

374 * build-aux/cross-options.pl: Use /x to make the regexp easier to
376 Fix the handling of $opt which resulted in all the argument to be
377 considered as optional.

416 (yypstate_allocated): Define for impure push parsers regardless of
417 whether the pull interface is also requested.
418 * tests/push.at (Push Parsing: Multiple impure instances): Extend to
419 check impure push parsers without the pull interface.
421 * data/yacc.c (yypstate_new): Don't try to invoke yyerror since
422 yyerror takes arguments specified by %parse-param while yypstate_new

1001 Improve C++ namespace support. Discussed starting at
1002 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
1003 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
1004 b4_namespace_close): New macros that interpret the %define variable
1005 "namespace" so its value can contain "::" to indicate nested

1009 * data/lalr1.cc (b4_namespace): Likewise.
1010 * data/location.cc (b4_namespace): Likewise.
1011 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
1012 inside a new table in the general %define entry. Document `%define
1013 namespace' there as well. Point the %name-prefix entry to it since it
1014 explains it more completely in the case of C++.
1015 (C++ Bison Interface): Mention `%define namespace' instead of
1017 (Table of Symbols): Remove the `%define push_pull' entry. The %define
1019 * tests/c++.at (Relative namespace references): New test case.
1020 (Absolute namespace references): New test case.
1021 (Syntactically invalid namespace references): New test case.

1047 muscle_percent_define_get_loc.
1048 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.

1057 Fix some error-reporting macro bugs.
1058 * data/bison.m4 (b4_cat): New.
1059 (b4_error, b4_error_at): Use b4_cat to send error directives directly
1060 to stdout so they don't become arguments to other macros. Update
1061 comments and add examples.
1062 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
1064 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
1065 after printing the error directive so that M4 doesn't report subsequent
1066 problems that are induced by this problem.
1067 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
1068 instead of just in them. Recognize @\n in both places. Both expand to
1069 the empty string. Needed by b4_cat.
1070 * tests/skeletons.at (Complaining during macro argument expansion):
1072 (Fatal errors make M4 exit immediately): New test case.

1112 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
1113 parsing requests here...
1114 * data/yacc.c: ... hack this to switch to push.c any time
1115 b4_use_push_pull_flag or the %define variable push_pull is set. This
1116 will go away when we mv push.c yacc.c.
1117 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1118 push parsing is not supported since unused %define variables are
1120 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
1121 * src/muscle_tab.h (muscle_percent_define_check_values): Update

1164 local variable `sep'.
1166 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
1168 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
1170 * src/print-xml.c: Prefer "const" after types; that's more consistent.
1171 (xml_printf): Indent just 1 space for level.
1172 (e_char, xlate_char): Remove.
1173 (xml_escape_string): Rewrite to avoid undefined behavior (used

1229 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
1230 and is a script that invokes bison. Tighten the code. Add comments.
1232 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

1244 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
1246 In impure push mode, don't allow more than one yypstate to be allocated

1248 * data/push.c (yypstate_allocated): New static global variable
1250 (yypull_parse): If yypstate_new returns 0, don't report it as memory
1251 exhaustion if yypstate_allocated is 1, but still return 2.
1252 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
1253 already 1. Otherwise, set it to 1.
1254 (yypstate_delete): Set it to 0.

1329 Get rid of broken %no-parser, -n, and --no-parser implementation and
1331 * TODO: Don't mention them.
1332 * doc/bison.1: Likewise.
1333 * doc/bison.texinfo (Decl Summary): Likewise.
1334 (Bison Options): Likewise.
1335 (Option Cross Key): Likewise.
1336 * src/getargs.c (no_parser_flag): Remove global variable.
1337 (usage): Don't print description of -n and --no-parser.
1338 (long_options): Remove --no-parser entry here.
1339 (getargs): Remove -n case in the switch here.
1340 * src/getargs.h (no_parser_flag): Remove extern.
1341 * tests/regression.at (Web2c Actions): Remove comment that mentions
1344 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
1346 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
1347 name user variables starting with `yy'. Just pass NULL instead of a
1348 dummy local &yylval to yypush_parse.
1349 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
1352 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
1354 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
1355 true since it's then always used regardless of whether yyoverflow is
1356 defined. Reported by Christian Burger at
1357 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
1358 * THANKS: Add Christian Burger.
1360 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1361 node names: say "Decl Summary" not "Bison Declaration Summary".
1363 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
1365 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
1366 determine whether this function has already complained about an invalid
1367 value for a %define boolean variable, don't check whether Bison has
1368 ever examined the value. As written, the check was a tautology.
1369 Instead, record and check for this complaint using a separate muscle.
1371 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
1373 Fix push parsing memory leak reported by Brandon Lucia at
1374 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
1375 * THANKS: Add Brandon Lucia.
1376 * data/push.c (yypstate_delete): Free the stack if it was reallocated
1377 but the parse never completed and thus freed it.
1378 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
1379 * tests/testsuite.at: Include push.at.
1380 * test/push.at: New.

1383 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
1385 Improve handling of multiple S/R conflicts in the same state and of S/R
1386 conflicts involving multiple reductions.
1387 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
1388 set for a state here or Bison will abort if it is reassigned on a
1389 later conflicted reduction in the same state.
1390 Similarly, don't finalize and assign the solved conflicts report here
1391 or it will be lost if it is reassigned on a later conflicted reduction
1393 (set_conflicts): Instead, assign them both here after all S/R conflicts
1394 in the state have been fully examined.
1395 * src/print.c (shift_set): Rename to...
1396 (no_reduce_set): ... this.
1397 (print_reductions): Update for rename, and add %nonassoc error action
1398 tokens to no_reduce_set so that, when printing the first remaining
1399 reduction on an error action token, the reduction is enclosed in
1401 (print_results): Update for rename.
1402 * tests/conflicts.at (Solved conflicts report for multiple reductions
1403 in a state): New test case.
1404 (%nonassoc error actions for multiple reductions in a state): New test
1407 * src/main.c (main): Don't depend on C99 features.
1409 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
1411 * build-aux/.cvsignore: Add compile.
1412 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
1415 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
1417 * bootstrap (slurp): Create target directories that don't exist.
1418 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
1420 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
1422 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
1424 * closure.c (closure): Likewise.
1425 * state.h (reductions): Comment sorting of rules.
1426 (state): Comment sorting of items.
1428 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
1430 Fix C++ test cases after recent Gnulib changes. Discussed starting at
1431 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
1432 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
1433 definition in order to avoid Gnulib headers since we don't use config.h
1435 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
1436 rather than AT_DATA so that config.h is included.
1438 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
1440 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
1441 instead of fprintf. Guard these functions with #if YYDEBUG instead of
1442 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
1443 and so that YYFPRINTF is guaranteed to be defined here.
1445 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
1447 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
1449 (muscle_percent_define_check_values): ... this more helpful function.
1450 Again, it's not used yet, but it will be.
1451 * src/muscle_tab.h: Likewise.
1453 Improve some comments in parser table construction.
1454 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
1455 (generate_states): Don't mention ruleset, which is internal to closure.
1456 * src/closure.c (closure): Explain sorting of core and itemset, which
1457 is required for this function to behave correctly.
1458 * src/closure.h (closure): Mention sorting.
1460 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
1462 * src/lalr.c (state_lookahead_tokens_count): For code readability,
1463 move the check for disabled transitions to an aver since conflict
1464 resolution hasn't happened yet.
1466 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1467 labels a state as inconsistent just because it has error transitions.
1468 The original form of this check appeared in revision 1.1 of lalr.c,
1469 which was committed on 1991-12-21. Now (at least), changing the
1470 consistency label on such a state appears to have no useful effect in
1471 any of the places it is examined, which I enumerate below. The key
1472 point to understanding each item in this enumeration is that a state
1473 with an error transition is labelled consistent in the first place only
1474 if it has no rules, so the check cannot matter for states that have
1475 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1476 to try to identify its conflicts, and a state must have *rules* to have
1477 conflicts. (2) Labelling a state as inconsistent will affect how
1478 action_row sets the default *rule* for the state. (3) Labelling a
1479 state as inconsistent will cause build_relations to add lookback edges
1480 to *rules* in that state.
1481 * src/state.h (struct state): Word the comment for member consistent
1484 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
1486 Don't depend on C99 features.
1487 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
1488 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
1489 * src/reader.c (check_and_convert_grammar): Fix for-loop.
1490 * src/state.c (state_mark_reachable_states): Fix for-loop.
1491 (state_remove_unreachable_states): Fix for-loop.
1493 Don't widen struct state with member reachable just to temporarily
1494 record reachability. Instead, use a local bitset.
1495 * src/state.h (struct state): Remove member.
1496 * src/state.c (state_new): Don't initialize it.
1497 (state_mark_reachable_states): Rename to...
1498 (state_record_reachable_states): ... this, and use bitset.
1499 (state_remove_unreachable_states): Use bitset.
1501 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
1503 * src/Makefile.am (yacc): Quote target action commands properly so
1504 that the yacc script isn't corrupt. Reported by Hans Aberg at
1505 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
1507 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
1508 the case of pure parsers. Reported by Frans Englich at
1509 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
1510 * THANKS: Add Frans Englich.
1512 * NEWS (2.3a+): In the %code entry, reference section `Bison
1513 Declaration Summary' from the manual now since the %code summary has
1515 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
1516 in the rules section must be terminated by semicolons.
1518 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
1520 Extend the front-end API for %define variables to more completely
1521 mirror the back-end. This will be useful in the future.
1522 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
1523 Update comments to mention the new front-end counterparts of these

1539 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
1541 * NEWS (2.3a+): Mention yesterday's state-removal change.
1542 (2.3a): Remove the %language entry, which was added after 2.3a.
1543 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
1544 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
1545 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
1546 tests/existing.at: Update copyright date.
1548 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1550 If conflict resolution makes states unreachable, remove those states,
1551 report rules that are then unused, and don't report conflicts in those

1568 an unused rule is discovered.
1570 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
1572 Minor code cleanup in parser table construction.
1573 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
1574 (new_itemsets, save_reductions): Update for rename to nitemset.
1575 * src/closure.c (nritemset): Rename to...
1576 (nitemset): ... this since the "r" appears to meaningless and isn't
1577 used in the comments.
1578 (closure): Update for rename.
1579 * src/closure.h (nritemset): Update extern to...
1580 (nitemset): ... this.

1665 Make it easy to share %define boolean variables between the front-end
1666 and back-end. Though not used yet, this will be useful in the future.
1667 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
1668 Bison uses of names rather than just skeleton uses of names.
1669 (b4_percent_define_get, b4_percent_define_ifdef): Rename

1676 * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
1677 muscle_percent_define_default): New functions mimicking
1678 b4_percent_define_flag_if and b4_percent_define_default.
1680 For %define variables, report locations for invalid values and
1682 * data/bison.m4 (b4_percent_define_flag_if): Read
1683 b4_percent_define_loc(VARIABLE) to report the location of an invalid
1685 (b4_percent_define_default): Save a special location in
1686 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

1705 * src/print.c (lookahead_set, state_default_rule): Remove.
1706 (print_reductions): Replace state_default_rule invocation with

1711 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
1713 * data/lalr1.java: Prefix all private members with yy.
1715 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
1717 Use YYFPRINTF instead of fprintf where appropriate. Reported by
1718 Sebastien Fricker at

1735 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
1737 Undo my 2007-02-07 change, switching back to the c-strcase module
1738 introduced in the 2007-02-03 change. Bruno Haible reported that
1739 the 2007-02-07 change would be dangerous in Turkish if we add a
1740 language whose name contains "i", since "i" is not lowercase "I"
1742 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
1743 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
1744 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
1745 * m4/.cvsignore: Remove strcase.m4.
1746 * src/getargs.c: Revert 2007-02-07 change, as follows.
1747 Include c-strcase.h.
1748 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
1750 2007-02-11 Bruno Haible <bruno@clisp.org>
1752 Enable the Java related testsuite tests when the only Java compiler
1753 found is a gcj < 4.3. Discussed at
1754 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
1755 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
1757 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
1759 * data/Makefile.am: Update copyright date.
1760 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
1761 yypstate_new returns NULL.
1762 (yypstate_new): Return NULL if malloc does.
1763 * src/reader.c (packgram): Move translation of rule actions from the
1764 beginning of packgram to...
1765 (check_and_convert_grammar): ... here right before packgram is invoked
1766 so it's easier to write more complete comments, and remove redundant
1769 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
1771 As in semantic actions, make @$ in %initial-action, %destructor, and
1772 %printer imply %locations.
1773 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
1775 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
1776 (@$ in %initial-action implies %locations,
1777 @$ in %destructor implies %locations,
1778 @$ in %printer implies %locations): ... these new test cases.
1780 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1782 Undo most of the 2007-02-03 change, switching to the strcase module
1783 now that gnulib strcase has been fixed.
1784 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
1785 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
1786 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
1787 * m4/.cvsignore: Add strcase.m4.
1788 * src/getargs.c: Revert 2007-02-03 change, as follows.
1789 Don't include c-strcase.h.
1790 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
1791 strcasecmp has "unspecified behavior" outside the POSIX locale,
1792 but it works fine in practice if at least one argument is ASCII,
1793 as is the case in Bison.
1795 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
1797 * tests/java.at: Skip tests if only one of javac/java is present.
1798 Reported by Joel E. Denny.
1799 * tests/atlocal.in: Adjust copyright years.
1801 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
1803 * data/lalr1.java (Stack): Work around old verifiers that disallow
1804 access to the private fields of an inner class, from the outer class.
1805 We can make Stack's fields public because user code doesn't have access
1806 to the instance of Stack used by parse(). Reported by Paul Eggert.
1808 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1810 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
1811 the right spot for these files?
1812 * bootstrap.conf (gnulib_modules): Add c-strcase.
1813 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
1815 * src/getargs.c: Include c-strcase.h.
1816 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
1817 to avoid unspecified behavior.
1819 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
1821 * doc/bison.texinfo (Decl Summary): Correct typo.
1823 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
1825 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
1826 Complain if the value does not match empty, "true" or "false".
1827 * data/c++.m4: Adjust default definitions of %define variables.
1828 * data/java.m4: Adjust default definitions of %define variables.
1829 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
1831 * tests/input.at (Boolean %define variables): Test new behavior.
1833 2007-01-29 Paolo Bonzini <bonzini@gnu.org>

1842 * data/java.m4: New.
1843 * data/lalr1.java: New.
1845 * doc/bison.texinfo: Put "A Complete C++ Example" under
1846 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
1847 under Other Languages.
1849 * src/getargs.c (valid_languages): Add Java.
1850 * src/getargs.h (struct bison_language): Update size of string fields.
1852 * tests/Makefile.am: Add java.at.
1853 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
1854 * tests/java.at: New.
1855 * tests/testsuite.at: Include it.
1857 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
1860 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
1861 at_directive_argv arguments so these no longer have to be global
1862 variables. Also, update the implementation for the following changes.
1863 (fail_for_at_directive_too_many_args,
1864 fail_for_at_directive_too_few_args): Add at_directive_name argument.
1865 (at_directive_name): Remove as at_directive_argv[0] will be used for
1867 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
1868 for the directive name.
1869 (at_directive_argc, at_directive_argv): Make these local within
1870 skel_lex instead of global.
1871 (INITIAL): Update directive start action for above changes.
1872 (SC_AT_DIRECTIVE_ARG): Rename to...
1873 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
1874 (SC_AT_DIRECTIVE_SKIP_WS): Update.
1875 (scan_skel): Move yylex_destroy to...
1876 (skel_scanner_free): ... here.
1877 * tests/skeletons.at (installed skeleton file name): Rename to...
1878 (installed skeleton file names): ... this.
1880 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
1882 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
1883 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
1884 Summary" not "Directives".
1885 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
1886 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
1887 since the former is now the more complete one.
1888 (Prologue Alternatives): Likewise and do the same for %defines.
1889 (Table of Symbols): Add summary of %code, add summary of %define, and
1890 move full %code documentation to...
1891 (Decl Summary): ... here for consistency with other entries in these
1893 Move %define entry in order to keep this list alphabetized.
1894 Reword %define entry a little to put less emphasis on the skeleton
1895 concept, which most users shouldn't have to think about.
1897 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
1899 Adjust to recent gnulib changes.
1900 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
1901 Add string.h, string_.h, unistd_.h, wchar_.h.
1902 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
1903 * src/system.h: Don't include <stpcpy.h>; this is now done by
1906 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
1908 Simplify implementation of unqualified %code, implement macros for
1909 uniform treatment of boolean %define flags. Document %define.
1910 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
1911 b4_percent_code_ifdef): New.
1912 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
1913 * data/c++.m4: Define default value for global_tokens_and_yystype.
1914 * data/glr.cc: Likewise.
1915 * data/location.cc: Use b4_percent_define_flag_if.
1917 * doc/bison.texinfo (Decl Summary): Document %define.
1919 * src/parse-gram.y (Unqualified %code): Change muscle name to
1921 (content.opt): Default to empty.
1923 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1925 Implement support for relative and absolute skeleton file names.
1926 Discussed starting at
1927 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
1928 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
1929 (Bison Options): Document in --skeleton entry.
1930 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
1931 full_skeleton can't necessarily hold all of pkgdatadir.
1932 If the specified skeleton file name contains a `/', don't prepend
1934 * src/parse-gram.y (prologue_declaration): If the specified skeleton
1935 file name contains a `/', prepend the grammar file directory.
1936 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
1937 * skeletons.at: New file.
1938 (relative skeleton file names): New test case.
1939 (installed skeleton file names): New test case.
1940 * tests/testsuite.at: Include skeletons.at.
1942 * bootstrap: Update copyright to 2007.
1944 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
1946 * bootstrap: Remove occurrences of .#bootmp from the files.
1948 2007-01-17 Akim Demaille <akim@epita.fr>
1950 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
1952 Use per-type %printer.
1954 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
1956 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

1964 2007-01-16 Akim Demaille <akim@epita.fr>
1966 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
1968 (Calc++ Scanner): Exit with failure if we can't open the input
1970 Accept "-" standing for stdin.
1971 (Calc++ Top Level): Print the result only if the parsing was
1974 2007-01-16 Akim Demaille <akim@epita.fr>
1976 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
1978 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
1979 and Joel E. Denny <jdenny@ces.clemson.edu>
1981 Clean up %define and %code implementation in M4 some. Most
1982 importantly, rename all related macros to be in the b4_percent_define
1983 and b4_percent_code namespaces. Also, complete support for `.' in
1984 %define variable names and %code qualifiers.
1985 * data/bison.m4 (b4_check_user_names): Check for special
1986 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1988 (b4_get_percent_define, b4_get_percent_code): Rename to...
1989 (b4_percent_define_get, b4_percent_code_get): ... these.
1990 Extend documentation with examples.
1991 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1992 b4_percent_define_skeleton_variables and
1993 b4_percent_code_skeleton_qualifiers.
1994 Expect any value for the %define variable `foo' to be stored in the
1995 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1996 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1997 expect any unqualified %code blocks to be stored in a macro named
1998 `b4_percent_code_unqualified'.
1999 Use m4_indir so that %define variable names and %code qualifiers can
2000 contain `.', which is allowed by the grammar parser.
2001 (b4_percent_define_default): New macro to set a default value for a
2003 (m4_wrap): Update wrapped code, and fix some underquoting.
2004 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2005 Expect grammar uses of %define variables and %code qualifiers to be
2006 defined in b4_percent_define_user_variables and
2007 b4_percent_code_user_qualifiers.
2008 * data/c++.m4: Use b4_percent_define_default rather than
2009 m4_define_default. Fix some underquoting. Skeleton usage of %define
2010 variable define_location_comparison now implies skeleton usage of
2011 %define variable filename_type.
2012 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2013 data/push.c, data/yacc.c: Update macro names.
2014 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2017 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2019 DJGPP specific issues.
2021 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2022 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2024 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2026 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2027 run parsers in all tests so that Valgrind is invoked during
2028 maintainer-check-valgrind.
2029 (Duplicate representation of merged trees): Free all semantic values.
2030 (Duplicated user destructor for lookahead): Likewise.
2032 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2034 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2035 command-line prefix.
2036 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2037 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2038 miss Valgrind messages.
2039 (Exploding the Stack Size with Malloc): Likewise.
2041 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2043 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2044 locals. Reported by Juan Manuel Guerrero at
2045 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2046 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2047 Fix some indentation also.
2048 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2049 explaining this issue.
2051 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2052 and Joel E. Denny <jdenny@ces.clemson.edu>
2054 Simplify union and prologue handling, and escape union and lex/parse
2055 params with digraphs.
2056 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2057 values to the empty string since these are no longer guaranteed
2058 initialized by the front-end.
2059 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2060 braces around b4_user_stype since this is no longer done by the
2062 * src/files.c, src/files.h (pre_prologue_obstack,
2063 post_prologue_obstack): Remove.
2064 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2065 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2066 with digraphs. This fixes lex params and parse params.
2067 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2068 * src/output.c (prepare): Remove muscle insertion of the prologues.
2069 (output): Remove freeing of pre_prologue_obstack and
2070 post_prologue_obstack.
2071 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2072 than prologue_augment for prologue parsing so you don't need prologue
2074 (grammar_declaration): For %union RHS, use `braceless' instead of
2075 "{...}" so that braces are already stripped and code is escaped with
2077 * src/reader.c (prologue_augment): Remove.
2078 (reader): Remove initialization of pre_prologue_obstack and
2079 post_prologue_obstack.
2080 * src/reader.h (prologue_augment): Remove.
2082 * data/c.m4: Remove stray parenthesis.
2084 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2086 Remove quotes from variables names in %define directives and from
2087 qualifiers in %code directives, and restrict the characters that are
2088 allowed in them to M4-friendly ones. For %define, continue to support
2089 the quoted form as a deprecated feature. Discussed starting at
2090 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2091 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2093 * doc/bison.texinfo (Prologue Alternatives): Update.
2094 (Decl Summary): In %defines entry, update mention of `%code requires'
2095 and `%code provides'.
2096 (C++ Location Values): Update %define uses.
2097 (Calc++ Parser Interface): Likewise.
2098 (Calc++ Parser): Likewise, and update `%code requires' uses.
2099 (Table of Symbols): Update %code documentation.
2100 * src/parse-gram.y (prologue_declaration): For %define variables, use
2101 `variable' instead of `STRING'.
2102 (grammar_declaration): For %code qualifiers, use `ID' instead of
2104 (variable): New nonterminal that takes an `ID' or a `STRING'.
2105 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2107 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2108 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2109 (%define errors): Update %define uses.
2111 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2113 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2114 instead of muscle_insert for %define values so that M4-special
2115 characters are replaced with digraphs.
2116 * tests/input.at (%define errors): Extend to check weird values.
2118 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2120 Instead of having skeletons declare all valid %define variables and
2121 %code qualifiers, provide macros that retrieve the associated values
2122 and build these lists automatically. Thus Bison will now warn when a
2123 variable or qualifier is not used by the skeleton in the current
2124 invocation regardless of whether it might sometimes be used by that
2125 skeleton in other invocations. Also, move all %define value macros to
2126 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2127 form, which is replaced by %code.
2128 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2129 (b4_check_user_names): ... this, and change the series of valid name
2130 arguments to a single list argument for names used in the skeleton
2131 similar to the existing list argument for names used in the grammar.
2132 Warn instead of complaining.
2133 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2134 values and %code code, to format %code code properly, and to build
2135 lists of all %define variables and %code qualifiers used in the
2136 skeleton: b4_skeleton_percent_define_variables and
2137 b4_skeleton_percent_code_qualifiers.
2138 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2140 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2141 the skeleton names lists can finish building first. In place of
2142 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2143 expect the lists b4_user_percent_define_variables and
2144 b4_user_percent_code_qualifiers.
2145 * data/c++.m4: Where setting default values for b4_parser_class_name,
2146 b4_location_type, b4_filename_type, b4_namespace, and
2147 b4_define_location_comparison, update their names to the
2148 b4_percent_define_ namespace.
2149 * data/glr.c: Don't use b4_check_percent_define_variables and
2150 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2151 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2152 (b4_parser_class_name, b4_namespace): Define these using
2153 b4_get_percent_define for parser_class_name and namespace.
2154 * data/location.cc: Use b4_get_percent_define.
2155 * data/push.c: Don't use b4_check_percent_define_variables and
2156 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2157 * data/yacc.c: Likewise, and don't call m4_exit in
2158 b4_use_push_for_pull_if or m4_wrap code will never execute.
2159 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2161 (muscle_grow_user_name_list): ... this for consistency with the
2162 terminology used in bison.m4.
2163 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2164 %define variable names, and rename muscle used_percent_define_variables
2165 to user_percent_define_variables.
2166 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2167 user_percent_code_qualifiers.
2169 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2170 {CODE} form is no longer accepted.
2171 * tests/input.at (Reject bad %code qualifiers): Rename to...
2172 (Reject unused %code qualifiers): ... this, and update test output.
2173 (%define error): Update test output.
2175 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2177 Check for unrecognized %define variables similar to checking for
2178 unrecognized %code qualifiers. Check for redefined %define variables.
2179 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
2181 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
2182 (b4_check_percent_define_variables): New, also wraps it.
2183 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
2184 variables using b4_check_percent_define_variables.
2185 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
2186 all those exercised in the test suite and all those listed in the
2187 `Default values' section of c++.m4. Are there others?
2188 * data/push.c, data/yacc.c: Declare no valid %define variables.
2189 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
2190 similar to muscle_find, but it works even when the muscle stores a
2192 (muscle_grow_used_name_list): New function for constructing the used
2193 name list muscles that b4_check_for_unrecognized_names requires.
2194 * src/parse-gram.y (prologue_declaration): Warn if a variable is
2195 %define'd more than once. Define the b4_used_percent_define_variables
2196 muscle with muscle_grow_used_name_list.
2197 (grammar_declaration): Abbreviate %code code with
2198 muscle_grow_used_name_list.
2199 * tests/input.at (%define errors): New.
2201 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2203 Provide warn_at, complain_at, and fatal_at function callbacks to the
2204 skeletons, and use this for %code qualifier complaints.
2205 * data/bison.m4 (b4_error_at): New, invoked by...
2206 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
2207 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
2208 @fatal_at(...@) directives.
2209 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
2210 qualifiers in b4_used_percent_code_qualifiers and to use
2212 * src/location.c, src/location.h (boundary_set_from_string): New global
2214 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
2216 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
2217 to b4_used_percent_code_qualifiers.
2218 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
2220 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
2221 (lineno): Rename to...
2222 (out_lineno): ... this so I don't misunderstand it again.
2223 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
2224 here; these newlines are in the input but not the output file.
2225 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
2226 (at_directive_perform): ... this new static function, and add handling
2227 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
2229 * tests/input.at (Reject bad %code qualifiers): Update test output with
2230 locations and extend.
2232 * tests/output.at (Output file name: [, Output file name: ]): Remove
2233 bogus comment about these tests failing.
2235 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
2237 Clean up b4_check_percent_code_qualifiers a little.
2238 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
2239 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
2240 documentation and add examples.
2241 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
2244 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2246 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
2247 unreliable -- especially when they're hidden inside another macro.
2248 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
2249 data/c.m4: Remove m4_divert(-1).
2250 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2251 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
2252 m4_divert_push(0) and m4_divert_pop(0).
2253 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
2254 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
2255 pushed and popped by m4sugar, should be first on the stack.
2257 Provide warn, complain, and fatal function callbacks to the skeletons.
2258 This provides more flexibility than m4_fatal, improves the error
2259 message format, and captures messages for translation. Discussed
2261 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
2262 * data/bison.m4 (b4_error): New, invoked by...
2263 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
2264 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
2265 directives. Because these M4 macros might be called when the current
2266 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
2267 the previous removal of uses of m4_divert, which caused trouble.
2268 (b4_check_percent_code_qualifiers): Use b4_complain instead of
2269 m4_fatal to report unrecognized %code qualifiers.
2270 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
2271 push parser requests.
2272 * data/glr.c: Use b4_complain instead of m4_fatal to report
2273 non-deterministic push parser requests.
2274 Update @output usage to @output(...@) form.
2275 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
2276 report missing %defines. Update @output usage to @output(...@) form.
2277 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
2279 * src/main.c (main): Invoke skel_scanner_free.
2280 * src/scan-skel.h (skel_scanner_free): Prototype new function.
2281 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
2282 obstack_for_string from flex-scanner.h.
2283 (YY_DECL): Use to declare skel_lex static.
2284 (decode_at_digraphs): Remove; now handled in the new
2285 SC_AT_DIRECTIVE_ARG start condition.
2286 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
2288 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
2289 at_directive_argv): New static globals.
2290 (INITIAL): Use fail_for_invalid_at.
2291 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
2292 recognize the start of a generalized `@directive(...@)' form and
2294 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
2295 directive args (using the new obstack_for_string), to decode the
2296 contained @ diagraphs, and to perform the directive. It recognizes
2297 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
2299 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
2300 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
2302 (scan_skel): Initialize obstack_for_string on the first call.
2303 (skel_scanner_free): New function to free obstack_for_string.
2304 * tests/input.at (Reject bad %code qualifiers): Update test output.
2306 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
2308 Consolidate the 4 prologue alternative directives (%code, %requires,
2309 %provides, and %code-top) into a single %code directive with an
2310 optional qualifier field. Discussed at
2311 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
2312 * NEWS (2.3a+): Rewrite the existing entry for the prologue
2314 * doc/bison.texinfo (Prologue Alternatives): Update.
2315 (Decl Summary): Update to %code "requires" and %code "provides".
2316 (Calc++ Parser): Update to %code "requires".
2317 (Table of Symbols): Remove entries for %requires, %provides, and
2318 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
2319 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
2320 are replaced by b4_percent_code_provides and b4_percent_code_requires,
2321 which are skeleton-specific.
2322 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
2323 declare what %code qualifiers it supports and to complain if any other
2324 qualifiers were used in the grammar.
2325 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
2326 and b4_user_code([b4_percent_code_provides]) in place of
2327 b4_user_requires and b4_user_provides.
2328 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
2329 Add b4_user_code([b4_percent_code_top]) and
2330 b4_user_code([b4_percent_code]).
2331 Invoke b4_check_percent_code_qualifiers.
2332 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2333 PERCENT_REQUIRES): Remove.
2334 (grammar_declaration): Remove RHS's for %code-top, %provides, and
2335 %requires. Rewrite the %code RHS as the unqualified form defining the
2336 muscle b4_percent_code. Add another RHS for the qualified %code form,
2337 which defines muscles of the form b4_percent_code_QUALIFIER and the
2338 b4_used_percent_code_qualifiers muscle.
2339 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
2340 PERCENT_REQUIRES): Remove.
2341 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
2342 %code "requires" and %code "provides".
2343 * tests/input.at (Reject bad %code qualifiers): New.
2345 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2347 Use the new code_props interface for destructors and printers.
2348 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
2349 printer_location members, and change the type of the destructor and
2350 printer members to code_props.
2351 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
2352 symbol_printer_get, semantic_type_destructor_set,
2353 semantic_type_printer_set, default_tagged_destructor_set,
2354 default_tagless_destructor_set, default_tagged_printer_set,
2355 default_tagless_printer_set): Use code_props in arguments and return
2356 types in place of char const * and location.
2357 (symbol_destructor_location_get, symbol_printer_location_get): Remove
2358 since the locations are now contained in the return of
2359 symbol_destructor_get and symbol_printer_get.
2360 * src/output.c (symbol_destructors_output, symbol_printers_output):
2362 (symbol_code_props_output): ... this to eliminate duplicate code.
2363 (output_skeleton): Update to use symbol_code_props_output.
2364 * src/reader.c (symbol_should_be_used): Update use of
2365 symbol_destructor_get.
2366 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
2367 Update uses of the various _destructor_set and _printer_set functions.
2368 * src/symtab.c: (default_tagged_destructor_location,
2369 default_tagless_destructor_location, default_tagged_printer_location,
2370 default_tagless_printer_location): Remove since we...
2371 (default_tagged_destructor, default_tagless_destructor,
2372 default_tagged_printer, default_tagless_printer): ... change the type
2373 of these to code_props.
2374 (symbol_new, semantic_type_new, symbol_destructor_set,
2375 semantic_type_destructor_set, symbol_destructor_get,
2376 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
2377 symbol_check_alias_consistency, default_tagged_destructor_set,
2378 default_tagless_destructor_set, default_tagged_printer_set,
2379 default_tagless_printer_set): Update.
2380 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
2381 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
2383 (symbol_print): Use SYMBOL_CODE_PRINT.
2385 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
2387 Use the new code_props interface for rule actions.
2388 * src/symlist.h (symbol_list): Replace action, action_location, and
2389 used members with a code_props action_props member.
2390 * src/reader.c (symbol_should_be_used, grammar_rule_check,
2391 grammar_midrule_action, grammar_current_rule_merge_set,
2392 grammar_current_rule_symbol_append, packgram): Update.
2393 * src/scan-code.h (translate_rule_action): Remove, no longer used.
2394 * src/scan-code.l (handle_action_dollar): Update.
2395 (translate_rule_action): Remove, no longer used.
2396 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
2398 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2400 Use the new code_props interface in parse-gram.y.
2401 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
2402 Update all uses of translate_* functions to use the new code_props
2403 interface and to use gram_scanner_last_string_free and
2404 code_scanner_last_string_free where possible.
2405 (grammar_declaration): symbol_list_destructor_set and
2406 symbol_list_printer_set now perform the translation, so don't do it
2407 here. Use gram_scanner_last_string_free where possible.
2408 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
2409 translate_code): Remove, no longer used.
2410 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
2411 symbol_list_printer_set): Perform code translation here rather than
2412 depending on the caller to do so.
2414 * src/symlist.h (struct symbol_list): Correct some documentation typos.
2415 * src/scan-gram.h (gram_last_string): Remove declaration.
2416 * src/scan-gram.l (last_string): Declare it static.
2418 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
2420 Encapsulate code properties and related functionality for the various
2421 destructors, printers, and actions into a code_props structure and
2422 interface. This patch merely implements code_props in scan-code.h and
2423 scan-code.l. Future patches will rewrite other modules to use it.
2424 Discussed starting at
2425 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2426 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
2427 consistently initialize const structs that have an empty location
2429 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
2430 to ensure consistency.
2431 * src/scan-code.h (code_props): New structure.
2432 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
2433 function, macro, and const global variable for initializing a
2434 code_props with no code.
2435 (code_props_plain_init, code_props_symbol_action_init,
2436 code_props_rule_action_init, code_props_translate_code): The rest of
2437 the new code_props functional interface. Among other things, the init
2438 functions set the code_props kind field so that
2439 code_props_translate_code will know whether to behave like
2440 translate_symbol_action, translate_rule_action, or translate_code.
2441 These old translate functions must remain until all other modules are
2442 updated to use the new code_props interface.
2443 (code_scanner_last_string_free): New function similar to
2444 gram_scanner_last_string_free.
2445 (code_scanner_free): Add documentation.
2446 * src/scan-code.l: Implement the new interface.
2447 (code_lex): Make it static, add a code_props* argument, and remove the
2449 (last_string): New static global similar to the one in scan-gram.l.
2450 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2452 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2453 code_props since Bison may one day use this information for destructors
2455 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
2456 (handle_action_dollar): Use symbol_list_n_get and set used flag
2457 directly since symbol_list_n_used_set is removed.
2458 (translate_action): Add a code_props* argument and remove the rule,
2459 action, and location arguments. Pass the code_props* on to code_lex.
2460 (translate_rule_action, translate_symbol_action, translate_code):
2461 Rewrite as wrappers around the new code_props interface.
2462 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
2463 it would eventually need to break the encapsulation of code_props.
2465 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2467 * etc/.cvsignore: New.
2469 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
2471 Add maintainer-push-check to run maintainer-check using push parsing in
2472 place of pull parsing where available.
2473 * Makefile.am (maintainer-push-check): New.
2474 * data/bison.m4 (b4_use_push_for_pull_if): New.
2475 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
2476 appropriately based on their existing values.
2477 (yypush_parse): Don't print push-parser-specific diagnostics if push
2478 parsing is being used in place of pull parsing.
2479 * data/yacc.c: If push parsing should replace pull parsing, redirect to
2481 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
2482 variable, and insert b4_use_push_for_pull_flag into muscles.
2483 * tests/Makefile.am (maintainer-push-check): New.
2485 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2487 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
2488 (whether successful or failed) so that yypush_parse can be invoked
2489 again to start a new parse using the same yypstate.
2490 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
2491 check multiple yypull_parse invocations on the same yypstate. For pull
2492 mode, extend to check multiple yyparse invocations.
2493 (Exploding the Stack Size with Alloca): Extend to try with
2495 (Exploding the Stack Size with Malloc): Likewise.
2497 * tests/calc.at (Simple LALR Calculator): Don't specify
2498 %skeleton "push.c" since %push-pull-parser implies that now.
2499 * tests/headers.at (export YYLTYPE): Don't check for the push
2500 declarations. Otherwise, this test case can't be used to see if push
2501 mode can truly emulate pull mode.
2502 * tests/input.at (Torturing the Scanner): Likewise.
2503 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
2504 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
2505 AT_YACC_IF, which now includes the case of push mode since %skeleton
2506 need not be used for push mode. This will be more intuitive once
2507 push.c is renamed to yacc.c.
2509 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
2511 For push mode, convert yyparse from a macro to a function, invoke yylex
2512 instead of passing a yylexp argument to yypull_parse, and don't
2513 generate yypull_parse or yyparse unless %push-pull-parser is declared.
2514 Discussed starting at
2515 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
2516 * data/bison.m4 (b4_pull_if): New.
2517 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
2518 * data/push.c: Improve M4 quoting a little.
2519 (b4_generate_macro_args, b4_parenthesize): Remove.
2520 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
2521 any time a pull parser is requested.
2522 Don't #define this as a wrapper around yypull_parse. Instead, when
2523 both push and pull are requested, make it a function that does that
2525 (yypull_parse): If there's a b4_prefix, #define this to
2526 b4_prefix[pull_parse] when both push and pull are requested.
2527 Don't define this as a function unless both push and pull are
2529 Remove the yylexp argument and hard-code yylex invocation instead.
2530 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
2532 * src/getargs.c (pull_parser): New global initialized to true.
2533 * getargs.h (pull_parser): extern it.
2534 * src/output.c (prepare): Insert pull_flag muscle.
2535 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
2536 (prologue_declaration): Set both push_parser and pull_parser = true for
2537 %push-pull-parser. Set push_parser = true and pull_parser = false for
2539 * src/scan-gram.l: Don't accept %push_parser as an alternative to
2540 %push-parser since there's no backward-compatibility concern here.
2541 Scan %push-pull-parser.
2542 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
2543 instead of %push-parser.
2544 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
2545 prototype it in the module that calls yyparse.
2546 * tests/input.at (Torturing the Scanner): Likewise.
2547 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
2549 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
2551 Update etc/bench.pl. Optimize push mode a little (the yyn change
2552 deserves most of the credit).
2553 * Makefile.am (SUBDIRS): Add etc subdirectory.
2554 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
2555 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
2556 yytoken, yyval, and yyloc declarations to...
2557 (yyparse or yypush_parse): ... here to improve performance. For
2558 yypush_parse invocations after the first, be sure to assign yyn its old
2560 (yypstate_new): Don't bother initializing the yyresult field since the
2561 initial value isn't used.
2562 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
2563 remove the #define that, in push mode, set it to yyps->NAME.
2564 * etc/Makefile.am: New.
2565 * etc/bench.pl: Remove and build it instead from...
2566 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
2567 "tests/bison" from the build directory by default rather than just
2568 invoking "bison" from $PATH.
2569 (calc_grammar): Update push parser code: don't declare yylval globally,
2570 don't define yyparse_wrapper, and don't #define yyparse.
2571 (bench_grammar): Update to check all working combinations of yacc.c,
2572 push.c, impure, pure, pull, and push.
2574 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2576 For push mode, add pull wrappers around yypush_parse.
2577 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
2578 (yypull_parse): New function wrapping yypush_parse.
2579 (yyparse): New #define wrapping yypull_parse.
2580 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
2582 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
2583 prototype yylex in the module that calls yyparse, and don't prototype
2584 yyparse there. Otherwise, the yyparse expansion won't compile.
2585 * tests/input.at (Torturing the Scanner): Likewise.
2587 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
2589 Enable push parsers to operate in impure mode. Thus, %push-parser no
2590 longer implies %pure-parser. The point of this change is to move
2591 towards being able to test the push parser code by running the entire
2592 test suite as if %push-parser had been declared.
2593 * data/push.c (yypush_parse): For impure mode, remove the
2594 yypushed_char, yypushed_val, and yypushed_loc arguments.
2595 Instead, declare these as local variables initialized to the global
2596 yychar, yylval, and yylloc.
2597 For the first yypush_parse invocation only, restore the initial values
2598 of these global variables when it's time to read a token since they
2599 have been overwritten.
2600 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
2602 * tests/calc.at (Simple LALR(1) Calculator): Always declare
2603 %pure-parser along with %push-parser since this test case was designed
2604 for pure push parsers.
2605 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
2606 (AT_YACC_OR_PUSH_IF): New.
2607 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
2608 add a note that it's still wrong for some cases (as it has been for a
2610 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
2611 %push-parser no longer implies %pure-parser.
2613 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2615 Remove some unnecessary differences between the pull parser code and
2616 the push parser code. This patch enables yynerrs in push mode.
2617 * data/push.c: Reformat M4 a little.
2618 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
2619 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
2620 because push mode is on. Instead, if pure mode is on, move yynerrs
2622 (b4_declare_parser_state_variables): ... here.
2623 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
2624 to yyps->NAME so it can be used in yypush_parse.
2625 (yypush_parse): Don't omit uses of yynerrs in push mode.
2627 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2629 Fix bug such that the first pushed token's value and location are
2630 sometimes overwritten (sometimes by %initial-action) before being used.
2631 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
2632 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
2633 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
2634 more closely mimic the pull parser logic.
2635 Don't copy the pushed token to yychar, yylval, and yylloc until it's
2636 time to read a token, which is after any initialization of yylval and
2638 (gottoken): Rename label to...
2639 (yyread_pushed_token): ... for clarity and to avoid infringing on the
2642 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
2644 Rearrange initialization of the parser state variables so that the
2645 skeleton doesn't have to have a copy for pull mode and another for push
2646 mode. This patch also fixes at least a bug such that yylloc was not
2647 initialized (with b4_location_initial_line and
2648 b4_location_initial_column) upon calling yypush_parse. However, that
2649 initialization now overwrites the first token's location;
2650 %initial-action assigning @$ already did the same thing, and both bugs
2651 will be fixed in a later patch.
2652 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
2653 (b4_declare_parser_state_variables): Remove initialization of yytoken,
2654 yyss, yyvs, yyls, and yystacksize.
2655 (yypstate_new): Remove initialization of some yypstate fields: yystate,
2656 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2658 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2659 yyps->NAME so it can be used in yypush_parse.
2660 (yyparse or yypush_parse): For yypush_parse, don't print the
2661 "Starting parse" diagnostic for invocations after the first.
2662 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2663 yypush_parse, only do it for the first invocation.
2664 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2665 initialization to occur in yypush_parse but only on the first
2668 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2670 * data/push.c: Add CPP guards around push parser declarations in both
2671 the header and the code file.
2672 In the code file, move the push parser declarations to the same place
2673 they appear in the header file.
2674 Clean up the M4 some, especially the inconsistent underquoting in
2675 some b4_c_function_def and b4_c_function_decl uses.
2677 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2679 Encapsulate the push parser state variables into an M4 macro so the
2680 push skeleton doesn't have to list them again for pull mode's yyparse.
2681 For push mode, remove yypush_parse's local equivalents of these
2682 variables to eliminate unnecessary copying between the two sets at
2683 run-time. This patch also fixes at least a bug related to multiple
2684 %initial-action invocations in push mode.
2685 * data/push.c (b4_declare_parser_variables): Rename to...
2686 (b4_declare_scanner_communication_variables): ... this for clarity and
2688 (b4_declare_yyparse_variables): Remove and move its contents to the one
2689 spot where it was invoked.
2690 (b4_declare_parser_state_variables): New macro containing the parser
2691 state variables required by push mode.
2692 (struct yypstate): Replace all fields but yynew with
2693 b4_declare_parser_state_variables.
2694 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2695 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2696 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2697 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2698 parser state variable declarations with
2699 b4_declare_parser_state_variables.
2700 Don't initialize parser state variables when calling yypush_parse since
2701 yypstate_new already does that.
2702 Invoke the user's initial action only upon the first yypush_parse
2704 Remove all code that copies between the local parser state variables
2707 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
2709 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
2710 prevent a name collision in a future patch where these names will
2711 sometimes be #define'd.
2712 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
2713 since it no longer has the same name as the existing argument.
2714 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
2716 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
2717 and Joel E. Denny <jdenny@ces.clemson.edu>
2719 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
2720 that the argument is case-insensitive, and there's no `=' here.
2721 For the %skeleton entry, mention that %language is better.
2722 (Bison Options): Likewise for --language and --skeleton. Move the
2723 --skeleton entry so that the `Tuning the parser' section is sorted
2724 alphabetically on long options.
2725 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
2726 %language directive in detail here; cross-reference the %language
2727 documentation instead.
2728 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
2729 `%require "2.3b"' so that the example is always up-to-date.
2730 (Table of Symbols): Add entries for %language and %skeleton.
2731 * examples/extexi (normalize): Instead of replacing every %require
2732 argument with the current Bison version, just substitute for
2733 `@value{VERSION}'. This guarantees that we're testing what actually
2734 appears in the documentation.
2735 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
2736 rather than `@VERSION@'.
2738 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2740 * NEWS: Reword the %language news a bit, and put it earlier.
2742 * src/getargs.c (skeleton_arg): Last arg is now location const *.
2743 Rewrite to simplify the logic.
2744 (language_argmatch): Likewise.
2745 (program_name): We now own this var.
2746 * src/getargs.h (struct bison_language): Use char[] rather than
2749 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
2751 * src/complain.c (program_name): Remove decl; no longer needed.
2752 * src/main.c (program_name): Remove; now belongs to getargs.
2754 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
2756 * NEWS: Document %language.
2758 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
2760 * data/c-skel.m4, data/c++-skel.m4: New files.
2761 * data/glr.c: Complain on push parsers.
2763 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
2765 (Decl Summary): Document %language and %skeleton.
2766 (Command line): Document -L.
2768 * examples/extexi: Rewrite %require directive.
2769 * examples/calc++/Makefile.am: Pass VERSION to extexi.
2771 * src/files.c (compute_exts_from_gc): Look in language structure
2773 (compute_file_name_parts): Check whether .tab should be added.
2774 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
2775 (language, skeleton_arg, language_argmatch): New.
2776 (long_options): Add --language.
2777 (getargs): Use skeleton_arg, add -L/--language.
2778 * src/getargs.h: Include location.h.
2779 (struct bison_language, language, skeleton_arg, language_argmatch): New.
2780 * src/output.c (prepare): Pick default skeleton from struct language.
2781 Don't dispatch C skeletons here.
2782 * src/parse-gram.y (PERCENT_LANGUAGE): New.
2783 (prologue_declaration): Add "%language" rule, use skeleton_arg.
2784 * src/scan-gram.l ("%language"): New rule.
2786 * tests/calc.at: Test %skeleton and %language.
2787 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
2788 (AT_GLR_IF): Look for %skeleton "glr.cc".
2789 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
2790 (AT_YACC_IF): Reject %language.
2792 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2794 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
2795 since it wasn't used; only the typedef name 'semantic_type' is needed.
2796 Also, omit trailing white space.
2798 * bootstrap: Sync from coreutils.
2799 (gnulib_extra_files): Add build-aux/announce.gen.
2800 (slurp): Adjust .gitignore files like .cvsignore files.
2801 * build-aux/announce-gen: Remove from CVS, since bootstrap
2804 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
2806 Make %push-parser imply %pure-parser. This fixes several bugs; see
2807 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
2808 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
2810 * data/push.c: Don't bother testing b4_push_if when deciding whether
2811 to expand b4_declare_parser_variables globally.
2812 (yypush_parse): Likewise in here.
2814 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
2815 (yy_reduce_print): Reformat M4 for readability.
2817 2006-12-15 Bob Rossi <bob@brasko.net>
2818 and Joel Denny <jdenny@ces.clemson.edu>
2820 * data/push.c (yypstate): Add typedef, and update all uses of
2821 struct yypstate to just yypstate.
2822 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
2824 2006-12-14 Bob Rossi <bob@brasko.net>
2826 * data/push.c (yypush_parse): Declare prototype regardless of
2829 2006-12-14 Bob Rossi <bob@brasko.net>
2831 * data/push.c (yyparse): Remove the prototype and the #define when in
2834 2006-12-13 Bob Rossi <bob@brasko.net>
2836 * data/push.c (yypstate_init): Rename to...
2837 (yypstate_new): ... this and use b4_c_function_def.
2838 (yypstate_delete): New.
2839 (yypush_parse): Change parameters yynval and yynlloc to be const.
2840 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
2841 yypstate_delete functions.
2843 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
2845 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
2846 strange test case titles. Reported by Bob Rossi.
2848 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
2850 * TODO: Add pointer to Sylvain Schmitz's work on static detection
2851 of potential ambiguities in GLR grammers.
2853 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
2855 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
2856 `bison ', use m4_index instead of m4_substr since chopping up a string
2857 containing M4-special characters causes problems here.
2859 Fix a couple of bugs related to special characters in user-specified
2860 file names, and make it easier for skeletons to compute output file
2861 names with the same file name prefix as Bison-computed output file
2863 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
2864 b4_parser_file_name and b4_spec_defines_file instead of
2865 @output_parser_name@ and @output_header_name@, which are now redundant.
2866 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2867 b4_parser_file_name, b4_spec_defines_file, and the new
2868 @basename(FILENAME@) instead of @output_parser_name@ and
2869 @output_header_name@, which inappropriately escaped the file names as
2871 * src/files.c (all_but_ext): Remove static qualifier.
2872 (compute_output_file_names): Move `free (all_but_ext)' to...
2873 (output_file_names_free): ... here since all_but_ext is needed later.
2874 * src/files.h (all_but_ext): Extern.
2875 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
2876 exactly what MUSCLE_INSERT_STRING used to do.
2877 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
2878 characters are escaped properly.
2879 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2881 For pkgdatadir muscle, maintain previous functionality by using
2882 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2883 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2884 digraphs would never be expanded. Hopefully no one has M4-special
2885 characters in his Bison installation path.
2886 * src/scan-skel.l: Don't parse @output_header_name@ and
2887 @output_parser_name@ anymore since they're now redundant.
2888 In @output, use decode_at_digraphs.
2889 Parse a new @basename command that invokes last_component.
2890 (decode_at_digraphs): New.
2891 (BASE_QPUTS): Remove unused.
2892 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
2893 (Output file name): New tests.
2895 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
2897 Warn about output files that are generated by the skeletons and that
2898 conflict with other output files.
2899 * data/glr.c: Don't generate the header file here when glr.cc does.
2900 * src/files.c (file_names, file_names_count): New static globals.
2901 (compute_output_file_names): Invoke output_file_name_check for files
2902 not generated by the skeletons and remove existing checks.
2903 (output_file_name_check): New function that warns about conflicting
2905 (output_file_names_free): Free file_names.
2906 * src/files.h (output_file_name_check): Declare.
2907 * src/scan-skel.l: Invoke output_file_name_check for files generated by
2909 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
2910 (Conflicting output files): New tests.
2912 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2914 * doc/bison.texinfo: Fix a couple of typos.
2916 2006-12-08 Bob Rossi <bob@brasko.net>
2918 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
2920 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
2922 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
2923 (yypush_parse): Rename yypvars argument to yyps and remove redundant
2925 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
2926 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
2928 2006-12-07 Bob Rossi <bob@brasko.net>
2929 and Joel Denny <jdenny@ces.clemson.edu>
2931 * data/push.c (yypvarsinit): Change return type from void* to struct
2932 yypvars*. No longer cast to void* on return.
2933 (struct yypvars): Remove yylen since it need not be remembered between
2934 yypushparse invocations.
2935 (yypushparse): Don't copy between yylen and pv->yylen.
2937 2006-12-05 Bob Rossi <bob@brasko.net>
2939 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
2940 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
2941 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
2942 (struct yypvars): Remove b4_declare_parser_variables.
2943 (yypvarsinit): Remove init code for removed variables.
2944 (global scope): Do not declare b4_declare_parser_variables if
2946 (yypushparse): Add b4_declare_parser_variables.
2947 Init new local variables, and remove init code for removed
2950 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
2951 and yyparse for other modes.
2952 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
2953 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
2954 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
2955 (AT_PURE_LEX_IF): True if pure or push parser.
2957 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
2959 Document Yacc prologue alternatives and default %destructor's and
2960 %printer's as experimental. Don't mention Java yet. Discussed at
2961 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
2962 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
2963 (2.3a): Annotate this entry to say the old forms of these features were

2978 * src/parse-gram.y (prologue_declaration): Implement.
2979 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
2980 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
2981 all but one occurrence of %name-prefix.
2982 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
2983 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
2984 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
2985 occurrence of each of %file-prefix and %output. Add check for %defines
2987 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
2988 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
2989 Remove the `=' from %output.
2991 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
2993 Don't escape $ in test case titles since Autoconf 2.61 now does that
2995 * tests/actions.at (Default %printer and %destructor are not for error
2996 or $undefined): Here.
2997 (Default %printer and %destructor are not for $accept): Here.
2998 * tests/input.at (Invalid $n and @n): Here.
3000 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
3002 Rename <!> to <>. Discussed starting at
3003 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
3004 * NEWS (2.3a+): Update.

3012 * tests/actions.at (Default tagless %printer and %destructor,
3013 Default tagged and per-type %printer and %destructor,
3014 Default %printer and %destructor are not for error or $undefined,
3015 Default %printer and %destructor are not for $accept,
3016 Default %printer and %destructor for mid-rule values): Update.
3017 * tests/input.at (Default %printer and %destructor redeclared,
3018 Unused values with default %destructor): Update.
3020 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
3022 Don't let %prec take a nonterminal.
3023 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
3025 * tests/input.at (%prec takes a token): New test checking that %prec
3026 won't take a nonterminal.
3028 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3030 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
3031 it was double-quoted.
3032 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
3033 grammar is maintained with Bison's highest standards.
3034 * src/getargs.c: Fix some typos in Doxygen comments.
3036 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3038 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3039 later. Reported by Paul Eggert in
3040 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
3041 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
3042 * src/scan-code.l (translate_action): Don't bother invoking
3043 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
3044 (code_scanner_free): Instead of invoking
3045 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
3047 * src/scan-gram.l (gram_scanner_free): Likewise.
3048 * src/scan-skel.l (scan_skel): Likewise.
3050 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
3052 * src/files.c (tr): Change return type to void.
3053 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
3054 has been called previously for the same key.
3055 (muscle_find): Return storage instead of value so that
3056 --enable-gcc-warnings doesn't produce warnings that the return discards
3057 const. aver that the value and storage are the same since storage
3058 could potentially be NULL when value is not.
3059 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
3062 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3064 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
3065 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
3066 us a slightly cleaner distribution, and also works.
3067 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
3070 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
3071 and Paul Eggert <eggert@cs.ucla.edu>
3073 Don't let Bison leak memory except when it complains.
3074 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
3075 (spec_defines_file, dir_prefix): Now char *, not const char *,
3076 since they are freed.
3077 * src/files.c: Likewise.
3078 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
3080 (tr): Now operates in-place. All uses changed.
3081 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
3083 (compute_file_name_parts, compute_output_file_names): Don't store
3084 read-only data in variables that will be freed.
3085 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
3086 src_extension, and header_extension.
3087 (output_file_names_free): New public function to free
3088 spec_verbose_file, spec_graph_file, spec_defines_file,
3089 parser_file_name, and dir_prefix.
3090 * src/getargs.c (getargs): Don't store read-only data in variables that
3092 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3093 (which previously existed but was unused), and quotearg_free.
3094 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3095 * src/muscle_tab.c: Likewise.
3096 (muscle_entry): Make the value char const *,
3097 and add a new storage member that is char * and can be freed.
3098 (muscle_entry_free): New private function.
3099 (muscle_init): Use it instead of free.
3100 (muscle_insert, muscle_grow): Update and use new storage member.
3101 (muscle_code_grow): Free the string passed to muscle_grow
3102 since it's not needed anymore.
3103 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3104 add a new `char *code' member.
3105 ("{...}"): Declare semantic type as code.
3106 * src/scan-code.h (translate_rule_action):
3107 (translate_symbol_action, translate_code, translate_action): Return
3108 `char const *' rather than `char *' since external code should not free
3110 * src/scan-code.l: Likewise.
3111 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3112 which is "{...}" in the parser.
3113 * tests/Makefile.am (maintainer-check-valgrind): Set
3114 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3116 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3118 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3119 expecting a non-zero exit status sets --leak-check=summary and
3120 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3121 this case, and we don't want to hear about it.
3123 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3125 * bootstrap (runtime-po/Makevars): Derive from po/Makevars

3228 * src/reader.c (packgram): Remove the `$' from each midrule symbol
3229 name for which the midrule value is referenced in any action.

3378 * bootstrap (usage, main program, symlink_to_gnulib): Add option
3379 --copy. Inspired by a suggestion from Bruno Haible.
3381 2006-10-03 Jim Meyering <jim@meyering.net>

3386 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3388 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

3584 not from $abs_top_builddir, since config.h moved.
3587 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
3588 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
3590 * src/parse-gram.y (symbol_declaration): Don't put statements
3591 before declarations; it's not portable to C89.
3592 * src/scan-code.l (handle_action_at): Likewise.
3594 * src/scan-code.l: Always initialize braces_level; the old code
3595 left it uninitialized and therefore had undefined behavior.
3597 Don't attempt to redefine 'assert', since it runs afoul of
3598 systems where standard headers (mistakenly) include <assert.h>.
3599 Instead, define and use our own alternative, called 'aver'.
3600 * src/reader.c: Don't include assert.h, since we no longer
3602 * src/scan-code.l: Likewise.
3603 * src/system.h (assert): Remove, replacing with....
3604 (aver): New function, taking a bool arg. All uses changed.
3605 * src/tables.c (pack_vector): Ensure that aver arg is bool,
3606 not merely an integer.
3608 2006-09-15 Bob Rossi <bob@brasko.net>
3610 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
3611 * data/c.m4 (YYPUSH): New.
3612 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
3613 * src/getargs.c (push_parser): New var.
3614 * src/getargs.h (push_parser): New declaration.
3615 * src/output.c (prepare): Add macro insertion of `push_flag'.
3616 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
3617 (prologue_declaration): Parse %push-parser.
3618 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
3619 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
3620 list of removed lines from the traces observed.
3621 (AT_CHECK_CALC_LALR): Added push parser tests.
3623 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
3625 * NEWS: Version 2.3a.
3626 * configure.ac (AC_INIT): Likewise.
3628 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
3629 "#define YYSTYPE int" that caused "make maintainer-check" to fail
3630 due to header ordering dependencies. I don't know why the #define
3633 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
3634 runtime cost when YYDEBUG is not defined, and so that some tests
3635 that used to fail now work. Problem and initial suggestion by
3637 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
3638 * data/glr.cc (b4_parser_class_name):
3639 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
3640 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
3641 (yydebug_) [YYDEBUG]: New member.
3642 (yycdebug_): Now defined only if YYDEBUG.
3643 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
3644 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
3645 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
3647 (debug_stream, set_debug_stream, debug_level, set_debug_level):
3648 Define only if YYDEBUG.
3649 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
3651 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
3652 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
3653 AT_CHECK_CALC_GLR_CC that are working now.
3655 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
3657 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
3658 We don't need them in glr.cc, and glr.c defines them.
3659 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
3660 assumes that defining it to anything is the same as defining
3661 it to 1. Problem reported by Paolo Bonzini.
3663 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
3665 * data/c.m4 (b4_null, b4_case): Define.
3666 * src/output.c (prepare_symbols): Use b4_null.
3667 (user_actions_output): Use b4_case.
3669 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
3671 * data/glr.c (b4_shared_declarations): Put start-header first,
3672 before any #includes that we generate, so that feature-test
3673 macros work. Problem reported by Michael Deutschmann in
3674 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
3675 * data/lalr1.cc: Likewise.
3676 * doc/bison.texinfo (Prologue): Document that feature-test macros
3677 should be defined before any Bison declarations.
3678 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
3679 that depend on location.hh after, not before, Bison decls, since
3680 we now include location.hh after the first user prologue.
3682 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
3683 Sander Brandenburg in
3684 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
3685 Also, fix minor white space and comment issues.
3686 (Prologue): Mention that it's better to define feature-test macros
3687 before Bison declarations. Problem reported by Michael Deutschmann.
3689 * README-cvs: Fix typo: "&" should be "&&". Problem reported
3691 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
3692 This adjusts to recent gnulib changes.
3694 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3696 Finish implementation of per-type %destructor/%printer. Discussed
3698 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
3700 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
3701 * NEWS (2.3+): Add a description of this feature to the default
3702 %destructor/%printer description.
3703 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
3704 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3705 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
3706 list node contains a semantic type.
3707 * src/symtab.c, src/symtab.h: Extend with a table that associates
3708 semantic types with their %destructor's and %printer's.
3709 (semantic_type_from_uniqstr, semantic_type_get,
3710 semantic_type_destructor_set, semantic_type_printer_set): New functions
3711 composing the public interface of that table.
3712 (symbol_destructor_get, symbol_destructor_location_get,
3713 symbol_printer_get, symbol_printer_location_get): If there's no
3714 per-symbol %destructor/%printer, look up the per-type before trying
3716 * tests/actions.at (Per-type %printer and %destructor): New test case.
3717 * tests/input.at (Default %printer and %destructor redeclared):
3718 Extend to check that multiple occurrences of %symbol-default in a
3719 single %destructor/%printer declaration is an error.
3720 (Per-type %printer and %destructor redeclared, Unused values with
3721 per-type %destructor): New test cases.
3723 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
3725 Require default %destructor/%printer to be declared using
3726 %symbol-default instead of an empty symbol list, and start working on
3727 new per-type %destructor/%printer. Discussed at
3728 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
3729 * NEWS (2.3+): Add %symbol-default to example.
3730 * bison.texinfo (Freeing Discarded Symbols): Likewise.
3731 (Table of Symbols): Add entry for %symbol-default.
3732 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
3733 (generic_symlist, generic_symlist_item): New nonterminals for creating
3734 a list in which each item is a symbol, semantic type, or
3736 (grammar_declaration): Use generic_symlist in %destructor and %printer
3737 declarations instead of symbols.1 or an empty list.
3738 (symbol_declaration, precedence_declaration, symbols.1): Update actions
3739 for changes to symbol_list.
3740 * src/reader.c: Update for changes to symbol_list.
3741 * src/scan-code.l: Likewise.
3742 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
3743 * src/symlist.c, src/symlist.h: Extend such that a list node may
3744 represent a semantic type or a %symbol-default in addition to just an
3745 ordinary symbol. Add switched functions for setting %destructor's and
3747 * tests/actions.at, tests/input.at: Add %symbol-default to all default
3748 %destructor/%printer declarations.
3750 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
3752 Whether the default %destructor/%printer applies to a particular symbol
3753 isn't a question of whether the user *declares* that symbol (in %token,
3754 for example). It's a question of whether the user by any means
3755 *defines* the symbol at all (by simply using a char token, for
3756 example). $end is defined by Bison whereas any other token with token
3757 number 0 is defined by the user. The error token is always defined by
3758 Bison regardless of whether the user declares it with %token, but we
3759 may one day let the user define error as a nonterminal instead.
3760 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
3761 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
3762 the meaning of "user-defined".
3763 * tests/actions.at (Default %printer and %destructor for user-declared
3764 end token): Rename to...
3765 (Default %printer and %destructor for user-defined end token): ...
3768 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
3769 computation of whether to apply the default, don't maintain a list of
3770 every Bison-defined symbol. Instead, just check for a first character
3771 of '$', which a user symbol cannot have, and check for the error token.
3773 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
3775 Don't apply the default %destructor or %printer to the error token,
3776 $undefined, or $accept. This change fits the general rule that the
3777 default %destructor and %printer are only for user-declared symbols,
3778 and it solves several difficulties that are described in the new test
3780 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
3781 * tests/actions.at (Default %printer and %destructor are not for error
3782 or $undefined, Default %printer and %destructor are not for $accept):
3785 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
3787 Allow %start after the first rule.
3788 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
3789 when parsing the first rule.
3790 (check_and_convert_grammar): Search for it here after all grammar
3791 declarations have been parsed. Skip midrules, which have dummy LHS
3793 * src/symtab.c (symbol_is_dummy): New function.
3794 * src/symtab.h (symbol_is_dummy): Declare it.
3795 * tests/input.at (%start after first rule): New test.
3797 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3799 Redo some of the previous commit: add back the ability to use
3800 non-aliased/undeclared string literals since it might be useful to
3801 those declaring %token-table.
3802 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3803 commit: don't worry about complaints from symbols_pack.
3804 * src/symtab.c (symbol_new, symbol_class_set,
3805 symbol_check_alias_consistency): Undo changes in previous commit: count
3806 each string literal as a new symbol and token, assign it a symbol
3807 number, and don't complain about non-aliased string literals.
3808 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3809 and token counts but does still set aliased tokens to the same number,
3810 symbol_pack_processor now leaves empty slots in the symbols array.
3812 * tests/regression.at (Undeclared string literal): Remove test case
3813 added in previous commit since non-aliased string literals are allowed
3815 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3816 remove unnecessary string literal declarations.
3817 * tests/sets.at (Firsts): Likewise.
3819 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
3821 Don't allow an undeclared string literal, but allow a string literal to
3822 be used before its declaration.
3823 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3824 symbols_pack complained.
3825 * src/symtab.c (symbol_new): Don't count a string literal as a new
3827 (symbol_class_set): Don't count a string literal as a new token, and
3828 don't assign it a symbol number since symbol_make_alias does that.
3829 (symbol_make_alias): It's not necessary to decrement the symbol and
3830 token counts anymore. Don't assume that an alias declaration occurs
3831 before any uses of the identifier or string, and thus don't assert that
3832 one of them has the highest symbol number so far.
3833 (symbol_check_alias_consistency): Complain if there's a string literal
3834 that wasn't declared as an alias.
3835 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3836 symbol_pack asserts that every token has been assigned a symbol number
3837 although undeclared string literals have not.
3838 * tests/regression.at (String alias declared after use, Undeclared
3839 string literal): New test cases.
3840 (Characters Escapes, Web2c Actions): Declare string literals as
3842 * tests/sets.at (Firsts): Likewise.
3844 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
3846 In the grammar scanner, STRING_FINISH unclosed constructs and return
3847 them to the parser in order to improve error messages.
3848 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
3849 SC_BRACED_CODE, SC_PROLOGUE): Implement.
3850 * tests/input.at (Unclosed constructs): New test case.
3851 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
3854 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
3857 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
3859 Handle string aliases for character tokens correctly.
3860 * src/symtab.c (symbol_user_token_number_set): If the token has an
3861 alias, check and set its alias's user token number instead of its own,
3862 which is set to indicate the alias. Previously, every occurrence of
3863 the character token in the grammar overwrote that alias indicator with
3865 * tests/input.at (String aliases for character tokens): New test.
3867 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
3869 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
3871 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
3873 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
3874 to prevent failures when building on older platforms.
3875 Check for autopoint failure.
3876 Set XGETTEXT_OPTIONS to values that check for C format strings,
3877 so that translators are warned about them (this also helps
3878 prevent core dumps).
3880 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3881 function, since it simplifies our code a bit.
3883 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
3884 rather than -W, so we don't get bogus warnings about sign comparisons.
3885 Add -Wpointer-arith, since that warning is useful (it reports code
3886 that does not conform to C89 and that some compilers reject).
3887 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
3888 since it's no longer needed.
3890 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
3892 Clean up scanners a bit.
3893 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
3894 definitions so gcc won't warn when obstack_for_string is unused.
3895 * src/scan-code.l: config.h and system.h are already #include'd by
3896 scan-code-c.c, so get rid of them here.
3897 * src/scan-gram.l: Likewise.
3898 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
3899 definitions rather than duplicating the rest of it.
3900 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
3902 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
3904 Suppress signed/unsigned comparison warnings for yycheck.
3905 * data/c.m4 (b4_safest_int_type): New macro.
3906 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
3907 a signed int type, cast it to b4_safest_int_type first.
3908 * data/yacc.c: Likewise.
3909 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
3912 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
3914 * doc/bison.texinfo: Fix some typos.
3916 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
3918 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
3919 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
3921 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
3922 the latest gnulib does this a different way.
3923 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
3924 translation was patched, so stop omitting it.
3926 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3928 Enable declaration of default %printer/%destructor. Make the parser
3929 use these for all user-declared grammar symbols for which the user does
3930 not declare a specific %printer/%destructor. Thus, the parser uses it
3931 for token 0 if the user declares it but not if Bison generates it as
3932 $end. Discussed starting at
3933 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
3934 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
3936 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
3937 * NEWS (2.3+): Mention.
3938 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
3939 declare a %destructor for a mid-rule's semantic value. It's just
3940 impossible to declare one specific to it.
3941 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
3942 code. Describe default %destructor form.
3943 * src/parse-gram.y (grammar_declaration): Parse default
3944 %printer/%destructor declarations.
3945 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
3946 and symbol_destructor_location_get rather than accessing the destructor
3947 and destructor_location members of struct symbol.
3948 (symbol_printers_output): Likewise but for %printer's.
3949 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
3951 * src/symtab.c (default_destructor, default_destructor_location,
3952 default_printer, default_printer_location): New static global
3953 variables to record the default %destructor and %printer.
3954 (symbol_destructor_get, symbol_destructor_location_get,
3955 symbol_printer_get, symbol_printer_location_get): New functions to
3956 compute the appropriate %destructor and %printer for a symbol.
3957 (default_destructor_set, default_printer_set): New functions to set the
3958 default %destructor and %printer.
3959 * src/symtab.h: Prototype all those new functions.
3960 * tests/actions.at (Default %printer and %destructor): New test to
3961 check that the right %printer and %destructor are called, that they're
3962 not called for $end, and that $$ and @$ work correctly.
3963 (Default %printer and %destructor for user-declared end token): New
3964 test to check that the default %printer and %destructor are called for
3965 a user-declared end token.
3966 * tests/input.at (Default %printer and %destructor redeclared, Unused
3967 values with default %destructor): New tests to check related grammar
3968 warnings and errors.
3970 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
3972 Clean up handling of %destructor for the end token (token 0).
3973 Discussed starting at
3974 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
3976 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
3978 Make the skeletons consistent in how they pop the end token and invoke
3980 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
3981 state, which has token number 0, since this would invoke the
3982 %destructor for the end token.
3983 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
3984 until after shifting the end token, or else it won't be popped.
3985 * data/yacc.c (yyparse): Likewise.
3987 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
3988 it's the end token. Upon termination, destroy an unshifted lookahead
3989 even when it's the end token.
3990 * data/lalr1.cc (yy::parser::parse): Likewise.
3991 * data/yacc.c (yyparse): Likewise.
3993 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
3994 value warnings for the end token when the user gives the end token a
3997 * tests/actions.at (Printers and Destructors): Test all the above.
3999 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4001 Update to latest gnulib and gettext versions.
4002 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4004 (gnulib_files): Add m4/warning.m4. Don't worry about files
4005 overwritten by autopoint.
4006 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4007 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4009 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4010 so that we can remove the intl files at a better time.
4011 (intl_files_to_remove): Remove aclocal.m4, since it gets
4012 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4013 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4014 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4015 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4016 Remove datarootdir hack; no longer needed.
4017 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4018 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4019 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4021 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4022 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4024 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4026 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4027 it with --assume-autoconf='latest-stable'.
4029 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4031 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4032 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4034 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4035 those from muscle_tab.c since the old ones are misleading.
4037 2006-07-13 Akim Demaille <akim@epita.fr>
4039 Support %define "KEY" {VALUE}.
4040 * src/scan-code.h, src/scan-code.l (translate_action)
4041 (translate_rule_action, translate_symbol_action, translate_code):
4042 Return char *, not const char *.
4043 * src/parse-gram.y (declaration): Rename as...
4044 (prologue_declaration): this.
4045 (string_content): Remove this nonterminal, use STRING.
4046 (braceless, content, content.opt): New nonterminal.
4048 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4050 * src/scan-gram.l (getargs.h): Don't include it.
4052 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4054 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4055 rather than a for-loop that declares a local bool variable. This
4056 should work around a compatibility problem with a Cray x1e C++
4057 compiler reported by Hung Nguyen in
4058 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4059 The for-loop was introduced in the 2004-11-17 change but I don't
4060 know why it was needed.
4062 2006-07-12 Akim Demaille <akim@epita.fr>
4064 * data/c.m4: Comment changes.
4066 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4068 * src/complain.c (error_message, ERROR_MESSAGE): New.
4070 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4071 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4073 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4075 * NEWS: Instead of %union, you can define and use your own union type
4076 YYSTYPE if your grammar contains at least one <type> tag.
4077 Your YYSTYPE need not be a macro; it can be a typedef.
4078 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4079 (Union Decl, Decl Summary): Document this.
4080 * data/glr.c (YYSTYPE): Implement this.
4081 * data/glr.cc (YYSTYPE): Likewise.
4082 * data/lalr1.cc (YYSTYPE): Likewise.
4083 * data/yacc.c (YYSTYPE): Likewise.
4084 * src/output.c (prepare): Output tag_seen_flag.
4085 * src/parse-gram.y (declaration, grammar_declaration):
4086 Use 'union_seen' rather than 'typed' to determine whether
4087 %union has been seen, since grammars can now be typed without
4089 (symbol_declaration, type.opt, symbol_def):
4090 Keep track of whether a tag has been seen.
4091 * src/reader.c (union_seen, tag_seen): New vars.
4093 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4094 * src/scan-code.l (untyped_var_seen): New variable.
4095 (handle_action_dollar): Adjust to above changes.
4096 (handle_action_dollar, handle_action_at):
4097 Improve overflow checking for outlandish numbers.
4098 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4099 avoid new diagnostics generated by above changes.
4100 * tests/regression.at (YYSTYPE typedef): Add test to check
4101 for type tags without %union.
4103 * src/symlist.c (symbol_list_length): Return int, not unsigned
4104 int, since callers expect int. This may need to get revisited
4105 once we have proper integer overflow checking.
4107 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4108 object is now static.
4110 * src/getargs.c (flags_argmatch): Return void, not int,
4111 to pacify ./configure --enable-gcc-warnings.
4113 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4114 since last_string is already defined to FLEX_PREFIX (last_string).
4116 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4118 Implement --warnings/-W.
4119 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4121 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4123 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4124 (warnings_args, warnings_types): New.
4125 (getargs, short_options, long_options): Accept -W/--warnings.
4126 Sort the options by alphabetical order, upper case letter right
4127 before its lower case.
4129 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4131 Change %merge result type clash warnings to errors. Discussed at
4132 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4133 * src/reader.c (record_merge_function_type): Use complain_at.
4134 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4135 declared later): Update test case results.
4137 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4139 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4140 to be in alphabetical order.
4141 (trace_args): Spelling fixes.
4143 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4145 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4146 so they don't collide with user-defined macros.
4147 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4148 this was never guaranteed, and now that we're using gnulib stdint,
4149 which defines int_fast16_t to long int, the problem is exposed.
4151 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4153 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4154 need the full POSIX semantics (and weren't implementing them
4157 Adjust to Autoconf 2.60 and today's gnulib.
4158 * bootstrap (gnulib_modules): Add stdint.
4159 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4160 no longer copies it.
4161 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4162 since stdint needs the former and wcwidth (which is now required
4163 by mbswidth) needs the latter.
4164 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4165 work around a compatibility glitch between gettext 0.14.6 and
4167 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4168 Do not check for uintptr_t, since new stdint module does the right
4170 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4171 Add stdint.h, stdint_.h, wcwidth.h.
4172 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4173 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4174 stdint.m4, wchar_t.m4, wcwidth.m4.
4175 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4176 usual order for ../lib/*.h files.
4177 (file_name_split): Use last_component, not base_name, to adjust
4179 * src/parse-gram.h: Include <strverscmp.h> in the usual order
4180 for ../lib/*.h files.
4181 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
4182 Define unconditionally, since we now assume the stdint module.
4183 * src/scan-skel.l: Include <dirname.h>.
4184 (BASE_QPUTS): Use last_component, not base_name.
4185 * src/system.h: Include <unlocked-io.h> in the usual order
4186 for ../lib/*.h files. Include <stdint.h> unconditionally,
4187 since we now use the stdint module.
4188 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4189 HAVE_UINTPTR_T, since we now use the stdint module.
4190 (base_name): Remove decl, since files now include <dirname.h>
4193 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4195 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
4197 * data/yacc.c, data/glr.c, data/location.cc: Use them.
4198 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
4200 * tests/calc.at: Adjust.
4202 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
4204 * data/c.m4 (b4_basename): New.
4205 (b4_syncline): Also output the location of its invocation (from
4207 (b4_user_action, b4_define_user_action, b4_user_actions)
4208 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
4209 (b4_user_stype): New.
4210 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
4212 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4214 In the grammar file, the first column is 1 not 0 on the first line as
4215 on every other line.
4216 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
4217 * tests/input.at (Torturing the Scanner): Update output.
4219 * src/scan-gram.l (scanner_cursor): Declare it static.
4221 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
4223 In warnings, say "previous declaration" rather than "first
4225 * src/symtab.c (redeclaration): Do that here.
4226 * src/reader.c (record_merge_function_type): In the case of a result
4227 type clash, report the previous declaration rather than the very first
4228 one in the grammar file.
4229 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4230 declared later): Add a third declaration to check this behavior.
4231 * tests/input.at (Incompatible Aliases): Update output.
4233 2006-06-27 Akim Demaille <akim@epita.fr>
4235 * doc/Doxyfile.in: New.
4236 * doc/Makefile.am: Use it.
4237 * src/lalr.h, src/symtab.h: Initial doxygenation.
4239 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4241 Don't miss %merge result type warnings just because the LHS types are
4242 declared after the %merge. This continues the effort of the previous
4244 * src/reader.c (get_merge_function): Don't set the merger type yet.
4245 (record_merge_function_type): New function for setting the merger type
4246 and checking for clashes.
4247 (grammar_current_rule_merge_set): Set the location of the %merge for
4249 (packgram): Invoke record_merge_function_type for each rule now that
4250 all symbol type declarations have been parsed.
4251 * src/reader.h (merger_list.type_declaration_location): New member
4252 storing the location of the first %merge from which the type for this
4253 merging function was derived.
4254 * src/symlist.h (symbol_list.merger_declaration_location): New member
4255 storing the location of a rule's %merge, if any.
4256 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4257 declared later): New test to catch the error fixed by the above patch.
4259 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4261 Get action warnings (grammar_rule_check) right even when symbol
4262 declarations appear after the rules. Discussed at
4263 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
4265 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
4266 Don't mistake the type of $$ in a midrule to be that of its parent
4268 * src/reader.c (grammar_current_rule_end): Don't invoke
4269 grammar_rule_check yet since not all symbol declarations may have been
4271 (grammar_midrule_action): Likewise.
4272 Don't record whether the midrule's $$ has been used yet since actions
4273 haven't been translated yet.
4274 Record the midrule's parent rule and its RHS index within the parent
4276 (grammar_current_rule_action_append): Don't translate the action yet
4277 since not all symbol declarations may have been parsed yet and, thus,
4278 warnings about types for $$, $n, @$, and @n can't be reported yet.
4279 (packgram): Translate the action and invoke grammar_rule_check now that
4280 all symbol declarations have been parsed.
4281 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4282 after parsing the entire grammar file, the symbol list here in the case
4283 of a midrule is actually the midrule's empty RHS, so reference its
4284 parent rule's RHS where necessary.
4285 On the other hand, now that you can already know it's a midrule, you
4286 aren't forced to think $$ has the same type as its parent rule's $$.
4287 (handle_action_at): In the case of a midrule, reference the parent rule
4289 * src/symlist.c (symbol_list_new): Initialize new midrule-related
4291 (symbol_list_length): Now that this is invoked after all rules have
4292 been parsed, a NULL symbol (rather than a NULL symbol list node)
4293 terminates a rule. symbol_list_print already does this correctly.
4294 * src/symlist.h (symbol_list.midrule_parent_rule,
4295 symbol_list.midrule_parent_rhs_index): New members so that midrules can
4296 remember their relationships with their parents.
4297 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
4298 fixed by the above patch.
4299 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
4301 (Unused values): ... this old test case and...
4302 (Unused values before symbol declarations): ... this new test case.
4303 This one is the same as `Unused values' except that all symbol
4304 declarations appear after the rules in order to catch the rest of the
4305 errors fixed by the above patch.
4307 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
4310 * src/reader.c (current_rule): Declare it static since it's no longer
4311 used outside this file.
4312 (grammar_current_rule_action_append): Remove redundant arguments from
4313 translate_rule_action invocation.
4314 * src/reader.h (current_rule): Remove this unused extern.
4315 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
4316 * src/scan-code.l (translate_rule_action): Likewise.
4318 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
4320 Clean up yesterday's patch.
4321 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
4323 * src/reader.c (grammar_current_rule_action_append): ... here for
4324 consistency with grammar_current_rule_symbol_append.
4325 * tests/regression.at (Braced code in declaration in rules section):
4326 Make yyerror and yylex static as usual.
4328 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
4330 Fix bug that mistakes braced code in a declaration in the rules section
4331 to be a rule action. Mentioned at
4332 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
4333 * src/scan-gram.l: Move midrule action detection from the start of the
4334 scanning of any braced code to...
4335 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
4336 action. For readability, use $2 and @2 rather than the equivalent
4338 * tests/regression.at (Braced code in declaration in rules section):
4339 New test to catch the error fixed by the above patch.
4341 Work on code readability some.
4342 * src/scan-code.l (current_rule): Get rid of this misleading and
4343 redundant declaration: it's actually extern'ed in reader.h.
4344 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
4345 translate_action): Add a rule argument and use it instead of the global
4347 (translate_rule_action): This already receives current_rule through an
4348 argument, so pass it on to translate_action instead of assigning
4349 current_rule to current_rule.
4350 (translate_symbol_action, translate_code): Pass rule = NULL to
4353 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
4355 Rename %before-definitions to %start-header and %after-definitions to
4356 %end-header. Don't use these declarations to separate pre-prologue
4357 blocks from post-prologue blocks. Add new order-independent
4358 declarations %before-header and %after-header as alternatives to the
4359 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
4360 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
4361 * NEWS (2.3+): Update for these changes.
4362 * data/glr.c (b4_before_definitions): Update to...
4363 (b4_start_header): ... this.
4364 (b4_after_definitions): Update to...
4365 (b4_end_header): ... this.
4366 * data/glr.cc: Likewise.
4367 * data/lalr1.cc: Likewise.
4368 * data/yacc.c: Likewise.
4369 * doc/bison.texinfo (The prologue): Update names, and replace remaining
4370 prologue blocks with %*-header declarations.
4371 (Calc++ Parser): Likewise.
4372 (Decl Summary): Update names.
4373 (Table of Symbols): Update description.
4374 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
4375 (PERCENT_END_HEADER): ... this.
4376 (PERCENT_BEFORE_DEFINITIONS): Update to...
4377 (PERCENT_START_HEADER): ... this.
4378 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4379 (declaration): Update token names and m4 macro names.
4380 When parsing %end-header and %start-header, invoke translate_code
4381 before muscle_code_grow, and no longer set global booleans to remember
4382 whether these declarations have been seen.
4383 Parse new %after-header and %before-header.
4384 * src/reader.c (before_definitions, after_definitions): Remove.
4385 (prologue_augment): Accept a new bool argument to specify whether to
4386 augment the pre-prologue or post-prologue.
4387 * src/reader.h (before_definitions, after_definitions): Remove these
4389 (prologue_augment): Add new bool argument.
4390 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
4391 (PERCENT_END_HEADER): ... this.
4392 (PERCENT_BEFORE_DEFINITIONS): Update to...
4393 (PERCENT_START_HEADER): ... this.
4394 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
4395 * tests/actions.at (Printers and Destructors): Update names.
4397 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
4399 Add comparison operators for C++ location classes. Discussed at
4400 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
4401 * data/c++.m4 (b4_define_location_comparison): New boolean %define
4402 declaration indicating whether filename_type has an operator==. If
4403 filename_type is `std::string', it defaults to `1', `0' otherwise.
4404 * data/location.cc: Iff b4_define_location_comparison is `1', add
4405 operator== and operator!= for class position and for class location.
4408 * src/scan-action.l: Remove unused file.
4409 * src/symtab.c (symbol_printer_set): Use printer_location not
4410 destructor_location.
4411 * src/symtab.h (struct symbol): Replace incorrect source comment for
4413 * tests/input.at (Incompatible Aliases): Update output with correct
4416 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
4418 Don't put the pre-prologue in the header file. For the yacc.c code
4419 file and the glr.c header and code files, move the pre-prologue before
4420 the token definitions. Add new %before-definitions and
4421 %after-definitions to declare code that will go in both the header file
4422 and code file. Discussed at
4423 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
4424 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
4426 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
4427 * NEWS (2.3+): Describe these changes.
4428 * data/glr.c (b4_pre_prologue): Move from within to before...
4429 (b4_shared_declarations): ... this.
4430 Add new b4_before_definitions before b4_token_enums.
4431 Add new b4_after_definitions at the end.
4432 * data/glr.cc (b4_pre_prologue): Replace with...
4433 (b4_before_definitions): ... this in the header file.
4434 (b4_after_definitions): New near the end of the header file.
4435 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
4436 code file right before including the header file.
4437 (b4_before_definitions): New in the previous position of
4438 b4_pre_prologue in the header file.
4439 (b4_after_definitions): New near the end of the header file.
4440 * data/yacc.c: Clean up some m4 quoting especially in the header file.
4441 (b4_token_enums_defines): In the code file, move to right before
4442 YYSTYPE for consistency with the header file.
4443 (b4_before_definitions): New right before b4_token_enums_defines in
4444 both the header and code file.
4445 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
4446 header and code file.
4447 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
4448 of prologues for %union dependencies.
4449 (Decl Summary): In %defines description, mention the effect of
4450 %before-definitions and %after-definitions on the header file.
4451 (Calc++ Parser): Forward declare driver in a %before-definitions rather
4452 than in the pre-prologue so that make check succeeds.
4453 (Table of Symbols): Add entries for %before-definitions and
4455 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
4456 %before-definitions.
4457 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
4458 (declaration): Parse those declarations and append to
4459 b4_before_definitions and b4_after_definitions, respectively.
4460 * src/reader.c (before_definitions, after_definitions): New bools to
4461 track whether those declarations have been seen.
4462 (prologue_augment): Add to the post-prologue if %union,
4463 %before-definitions, or %after-definitions has been seen.
4464 * src/reader.h (before_definitions, after_definitions): New extern's.
4465 * src/scan-gram.l: Scan the new declarations.
4466 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
4467 prologue block in a %before-definitions or a %after-definitions based
4468 on whether the %union is declared.
4469 * tests/regression.at (Early token definitions with --yacc, Early token
4470 definitions without --yacc): Move tests for token definitions into the
4471 post-prologue since token names are no longer defined in the
4474 2006-06-20 Akim Demaille <akim@epita.fr>
4476 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
4477 (symbol_get): Use it.
4478 * src/parse-gram.y: Use it.
4480 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
4482 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
4483 build succeeds when configured with --enable-gcc-warnings.
4485 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4487 * src/parse-gram.y (char_name): New function.
4488 (CHAR, STRING, string_content): For %printer, properly escape.
4489 (ID): Prefer fputs to fprintf.
4490 (id): Reindent to be consistent with other rules.
4491 Properly quote char.
4493 The Translation Project changed its way of publishing translations
4494 to maintainers. I haven't received any responses to my request
4495 for supporting the old way, or for documenting the new way. I
4496 have modified 'bootstrap' to use screen scraping
4497 (in this case, HTML scraping). This is unreliable and inelegant,
4498 but I don't see any better way. Yuck.
4499 * bootstrap (TP_URL, WGET_COMMAND): New vars.
4500 (get_translations): New function, which uses HTML scraping to
4501 deduce locations of latest translations.
4502 Use this function to grab both bison and bison-runtime .po files.
4503 Don't bother priming the pump for the runtime-po domain any more,
4504 as it's now translated better than bison is.
4506 2006-06-19 Akim Demaille <akim@epita.fr>
4508 * src/scan-gram.l: No longer "parse" things after `%union' until
4509 `{'. Rather, return a single "%union" token.
4510 No longer make symbols: return strings, and leave the conversion
4511 to symbols to the parser.
4512 (SC_PRE_CODE, token_type): Remove.
4513 * src/parse-gram.y (%union): New field `character'.
4516 (ID, ID_COLON): Now that the scanner no longer makes them
4517 identifiers, adjust all uses to invoke symbol_get.
4518 (id_colon): New, wraps the conversion from string to symbol.
4519 (%union): Accept a possible union_name.
4520 (symbol): Now can be a char.
4521 * data/c.m4 (b4_union_name): Leave a default value.
4522 * data/glr.c, data/yacc.c: Use it.
4524 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
4526 For associating token numbers with token names for "yacc.c", don't use
4527 #define statements unless `--yacc' is specified; always use enum
4528 yytokentype. Most important discussions start at:
4529 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,

4532 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
4533 * NEWS (2.3+): Mention.
4534 * data/c.m4 (b4_yacc_if): New.
4535 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
4537 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
4538 on token name definitions.
4539 * src/getargs.c (usage): Capitalize `Yacc' in English.
4540 * src/output.c (prepare): Define b4_yacc_flag.
4541 * tests/regression.at (Early token definitions): Test that tokens names
4542 are defined before the pre-prologue not just before the post-prologue.
4543 Remove this test case and copy to...
4544 (Early token definitions with --yacc): ... this to test #define's.
4545 (Early token definitions without --yacc): ... and this to test enums.
4547 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
4549 * NEWS: Reword the post-2.3 change to not be so optimistic about
4550 removing the old "look-ahead" spelling.
4551 Update previous look-ahead/lookahead change reports.
4552 * REFERENCES: look-ahead -> lookahead (since that's
4553 what he actually wrote).

4555 look-ahead -> lookahead
4557 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
4559 For consistency, use `lookahead' instead of `look-ahead' or

4636 * TODO: Add request from Nelson H. F. Beebe to be able to install
4637 Bison without installing the yacc script.
4639 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
4641 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
4642 and yytext if they're already #define'd.
4643 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
4644 * src/scan-code-c.c: ... here.
4645 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

4650 Get Bison to build again when configured with --enable-gcc-warnings.
4651 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
4653 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
4654 loc argument as it shadows a global.
4655 * src/scan-gram.l: Remove stray comma that prevents boundary_set
4658 * src/.cvsignore: Add scan-code.c.
4660 2006-06-07 Akim Demaille <akim@epita.fr>
4662 * src/scan-gram.l: Move the "add a trailing ; to actions" code
4664 * src/scan-code.l: here.
4665 * tests/input.at (Torturing the Scanner): Fix another location
4668 2006-06-07 Akim Demaille <akim@epita.fr>
4670 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
4672 2006-06-06 Akim Demaille <akim@epita.fr>
4674 Extract the parsing of user actions from the grammar scanner.
4675 As a consequence, the relation between the grammar scanner and
4676 parser is much simpler. We can also split "composite tokens" back
4678 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
4679 * src/scan-gram.l (add_column_width, adjust_location): Move to and
4681 * src/location.h, src/location.c (add_column_width)
4682 (location_compute): these.
4683 Fix the column count: the initial column is 0.
4684 (location_print): Be robust to ending column being 0.
4685 * src/location.h (boundary_set): New.
4686 * src/main.c: Adjust to scanner_free being renamed as
4688 * src/output.c: Include scan-code.h.
4689 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
4691 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
4692 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
4693 which is now, again, a separate token.
4694 Adjust all dependencies.
4695 Whereever actions with $ and @ are used, use translate_code.
4696 (action): Remove this nonterminal which is now useless.
4697 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
4698 (grammar_current_rule_action_append): Use translate_code.
4699 (packgram): Bound check ruleno, itemno, and rule_length.

4705 (YY_DECL): Rename as...
4707 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
4708 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
4709 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
4710 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

4715 * src/scan-gram.l (rule_length, rule_length_overflow)
4716 (increment_rule_length): Remove.
4717 (last_braced_code_loc): Rename as...
4718 (gram_last_braced_code_loc): this.
4719 Adjust to the changes of the parser.
4720 Move all the handling of $ and @ into...
4721 * src/scan-code.l: here.
4722 * src/scan-gram.l (handle_dollar, handle_at): Remove.

4735 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4737 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4738 Use Akim's wording from
4739 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
4741 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
4743 Between Bison releases, manually append `+' to the previous Bison
4744 release number, and use that as a signal to automatically print the
4745 ChangeLog's CVS Id keyword from --version. Discussed starting at
4746 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
4747 * ChangeLog: Add Id header.
4748 * configure.ac (AC_INIT): Append `+' to `2.3'.
4749 * src/.cvsignore: Add revision.c.
4750 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
4751 (BUILT_SOURCES): Add revision.c.
4752 (revision.c): New target rule. This file defines a new global variable
4753 named revision. It initializes it with either the Id from ChangeLog
4754 or, if VERSION doesn't contain `+', with the empty string.
4755 * src/getargs.c (version): Print the value of revision.
4756 * src/revision.h: Extern revision.
4758 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4760 * NEWS: Version 2.3.
4761 * configure.ac (AC_INIT): Likewise.
4763 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4765 * data/glr.c (YYRECOVERING): Define to be a function-like macro
4766 with no arguments, not as an object-like macro. This is for
4767 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
4768 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
4769 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
4772 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
4774 * src/getargs.c (usage): Back out yesterday's modification of the
4775 --help output so that we don't have to wait for translation before
4778 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4780 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
4781 Problem reported by Akim Demaille.
4783 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
4785 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
4787 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4789 * data/yacc.c (yy_reduce_print): Omit trailing white space in
4790 generated source code. Problem reported by Frans Englich in
4791 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
4793 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
4795 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
4796 shell, not within 'make', so that 'make' by an ordinary builder
4797 (using GNU make) does not worry about configuring gzip. This also
4798 works around a bug reported independently by Keith Thompson and by
4799 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
4800 stderr rather than stdout, messing up the build logs.
4802 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4804 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
4805 to make sure that YYID will never be unused. This fixes a 'make
4806 maintainer-check' failure caused by the recent changes to the 'Trivial
4807 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
4809 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
4811 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
4813 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
4814 state before an empty RHS is always resolved here. Only the location
4815 of that state is guaranteed to be resolved, and that's enough. This
4816 fixes the remaining bug reported by Derek M. Jones in
4817 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4818 * tests/glr-regression.at (Uninitialized location when reporting
4819 ambiguity): Test the above case.
4820 Also, the embedded comments in this test case claim it checks the case
4821 of an empty RHS that has inherited the initial location. However, the
4822 corresponding LHS was already resolved, so yyresolveLocations didn't
4823 actually have reason to modify it. Fix this by forcing
4824 nondeterministic operation at the beginning of the parse.
4826 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4828 * data/c.m4 (b4_yy_symbol_print_generate):
4829 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
4830 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
4831 of the bugs reported today by Derek M Jones in
4832 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
4833 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
4834 defined to be a type name without parens or brackets.
4835 (Location Type): Similarly for YYLTYPE.
4836 * tests/regression.at (Trivial grammars): Put in a test for this
4837 bug that will be caught by 'make maintainer-check' (though not,
4838 alas, by 'make check' unless your compiler is picky).
4840 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4842 * NEWS: Version 2.2.
4843 * configure.ac (AC_INIT): Likewise.
4845 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
4847 * data/glr.c (yyreportTree): Make room in yystates for the state
4848 preceding the RHS. This fixes the segmentation fault reported by Derek
4850 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
4851 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
4852 to the user. Reported for yyreportTree by Derek M. Jones later in the
4854 * THANKS: Add Derek M. Jones.
4855 Update my email address.
4856 Fix typo in Steve Murphy's name.
4858 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4860 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
4861 checking against YYLAST that caused the parser to miss a potential
4862 alternative in its diagnostic.
4863 Problem reported by Maria Jose Moron Fernandez in
4864 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
4865 * data/lalr1.cc (yysyntax_error_): Likewise.
4866 * data/yacc.c (yysyntax_error): Likewise.
4867 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
4868 tokens, in case we run into an older C compiler.
4869 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
4870 Use them to check for the off-by-one error fixed above.
4872 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
4873 YYSIZE_T, not size_t.
4874 * tests/regression.at (Trivial grammars): New test, to catch
4875 the error fixed by the above patch.
4877 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4879 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
4881 Reported by Steve Murphy.
4883 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4885 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
4886 * data/glr.cc: b4_location_flag is now b4_locations_flag.
4888 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4890 Implement --trace=m4.
4891 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
4892 * src/output.c (output_skeleton): When set, pass -dV to m4.
4894 Factor the handling of flags in m4.
4895 * src/output.c (prepare): Rename the muscle names debug, defines,
4896 error_verbose to debug_flag, defines_flag, error_verbose_flag.
4897 * data/c.m4: Adjust.
4898 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
4899 Use b4_define_flag_if to define other b4_FLAG_if macros.
4900 (b4_location_if): As a consequence, rename as...
4901 (b4_locations_if): this, for consistency.
4902 Adjust all the skeletons.
4904 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4906 * etc/bench.pm: Shorten bench names.
4908 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
4910 * src/output.h, src/output.c (error_verbose): Move to...
4911 * src/getargs.h, src/getargs.c: here.
4913 Adjust dependencies.

4917 * data/c.m4 (b4_copyright): Put the special exception for Bison
4918 skeletons here, so we don't have to put it in each skeleton. All
4919 uses changed. Suggested by Akim Demaille. Also, wrap the
4920 copyright notice, in case it is longer than 80 columns. Replace
4921 comma by newline after title.
4923 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4925 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
4926 incompatibility, not a bug. Mention that it wasn't fixed as of
4929 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4931 * examples/extexi: Enforce the precedence of concatenation over
4933 Reported by Tommy Nordgren.
4935 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
4937 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
4938 with the member "token".
4939 Reported by Martin Nylin.
4941 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
4943 * data/glr.c: Switch to Bison 2.2 special-exception language in
4944 the copyright notice. Use more-regular format for titles and
4946 * data/glr.cc: Likewise.
4947 * data/location.cc: Likewise.
4948 * data/yacc.cc: Likewise.
4949 * doc/bison.texinfo (Conditions): Document this.
4950 * NEWS: likewise. Upgrade version to 2.2.
4952 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
4954 * data/glr.cc: Remove dead code.
4956 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4958 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
4959 that variable and the line breaks the bootstrap. Problem reported
4960 by Juan M. Guerrero.
4962 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4964 * doc/bison.texinfo (Multiple start-symbols): New.
4966 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
4968 * etc/README, etc/bench.pl: New.
4970 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
4972 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
4974 Reported by Mickael Labau.
4975 * tests/input.at (Torturing the Scanner): Test it.
4977 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
4979 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
4980 Problem reported by Bob Rossi.
4982 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
4984 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
4985 and didn't really work.
4986 For the index, use @ifnotinfo, not @iftex.
4987 Minor cleanups of spacing and terminology.
4989 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4991 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
4992 of AT_NAME_PREFIX when %name-prefix is not used.
4994 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
4996 Apply --prefix to C++ skeletons too: they change the namespace.
4997 The test suite already exercize these cases.
4998 * data/c++.m4 (b4_namespace): New.
4999 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5000 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5001 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5002 * doc/bison.texinfo: Document it.
5003 (Option Cross Key): Use @multitable in all formats. It looks
5004 nicer, even in TeX outputs.
5005 (Rules): Use the same code whatever the output type is.
5006 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5007 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5008 * tests/calc.at: Use it, instead of hard coding `yy'.
5010 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5012 * TODO: Remove dead items.
5014 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5016 * doc/FAQ: Remove, merged into...
5017 * doc/bison.texinfo (FAQ): this.
5018 * doc/Makefile.am (EXTRA_DIST): Adjust.
5020 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
5022 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
5024 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
5025 * doc/bison.texinfo (Calc++ Scanner): Use it.
5027 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
5029 Fix two nits reported by twlevo, plus one more that I discovered.
5031 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5032 this is the usual Bison style.
5033 * src/location.h (location_print): Likewise.
5035 * src/reader.h (token_name): Likewise.
5037 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5039 Fix some nits reported by twlevo.
5040 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5041 and "POSIX". Use more-modern syntax for URLs. Mention C++
5042 and ask for Java. Don't hardwire OS version numbers. Add
5044 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5045 * src/conflicts.c (solved_conflicts_obstack): Now static.
5047 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5049 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5050 page. Say "you can use it" not "you may use it" as on the web page;
5051 we're describing capabilities not granting permission.
5053 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5055 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5056 shadowing warnings. Use usual patter for iterating through RHS.
5057 * tests/glr-regression.at
5058 (Uninitialized location when reporting ambiguity):
5059 Modify yylex so that it uses its argument, rather than trying
5060 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5061 const char -> char const.
5063 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5064 Don't use tabs inside commands; it messes up 'ps'.
5065 Problem reported by twlevo.
5067 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5069 * tests/glr-regression.at (Uninitialized location when reporting
5070 ambiguity): New test case.
5071 * data/glr.c (yyresolveLocations): New function, which uses
5073 (yyresolveValue): Invoke yyresolveLocations before reporting an
5075 * doc/bison.texinfo (Default Action for Locations): Note
5076 YYLLOC_DEFAULT's usage for ambiguity locations.
5077 (GLR Semantic Actions): Cross-reference those notes.
5079 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5081 * tests/glr-regression.at (Leaked semantic values when reporting
5082 ambiguity): Remove unnecessary union and type declarations.
5083 (Leaked lookahead after nondeterministic parse syntax error): New test
5085 * data/glr.c (yyparse): Check for zero stacks remaining before
5086 attempting to shift the lookahead so that you don't lose it.
5088 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5090 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5091 * tests/glr-regression.at (Leaked semantic values when reporting
5092 ambiguity): New test case.
5093 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5094 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5095 now unnecessary yystackp parameter.
5096 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5097 destructors can be called.
5099 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5100 in existing testcases.
5102 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5104 Don't leak semantic values for parent RHS when a user action cuts the
5105 parser, and clean up related code a bit.
5106 * tests/glr-regression.at (Leaked merged semantic value if user action
5107 cuts parse): Rename to...
5108 (Leaked semantic values if user action cuts parse): ... this. Add check
5109 for leaked parent RHS values.
5110 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5111 between an unresolved state (non-empty chain of semantic options) and
5112 an incomplete one (signaled by an empty chain).
5113 (yyresolveStates): Document the interface. Move all manipulation of a
5114 successfully or unsuccessfully resolved yyGLRState to...
5115 (yyresolveValue): ... here so that yyresolveValue always leaves a
5116 yyGLRState with consistent data and thus is easier to understand.
5117 Remove the yyvalp and yylocp parameters since they are always just
5118 taken from the yys parameter. When reporting a discarded merged value
5119 in debugging output, note that it is incompletely merged. Document the
5121 (yyresolveAction): If resolving any of the RHS states fails, destroy
5122 them all rather than leaking them. Thus, as long as user actions are
5123 written to clean up the RHS correctly, yyresolveAction always cleans up
5124 the RHS of a semantic option. Document the interface.
5126 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5128 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
5129 led to a segmentation fault in GNU Pascal. Problem reported
5132 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
5134 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
5135 mid-rule action inside a nonterminal symbol in order to declare a
5136 destructor for its semantic value.
5138 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
5140 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
5141 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
5142 __cplusplus && ! defined _STDLIB_H && !
5143 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5144 defined free))]: Include <stdlib.h> rather than rolling our own
5145 declarations of malloc and free, to avoid problems with
5146 incompatible declarations (using 'throw') C++'s stdlib.h. This
5147 should fix Debian bug 340012

5159 * NEWS: Version 2.1a.
5160 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
5161 since C99 requires this.
5163 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
5165 * m4/c-working.m4: New file.
5166 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
5168 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
5170 * Makefile.maint: Merge from coreutils.
5172 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
5174 More portability fixes for problems summarized by Nelson H. F. Beebe.
5176 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
5177 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
5178 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
5179 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

5185 More portability fixes for problems summarized by Nelson H. F. Beebe.
5187 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
5188 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
5190 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
5191 nodist_PROGRAMS, since we don't need to actually compile the
5192 example if we're just doing a plain 'make'. This avoids bothering
5193 the installer unnecessarily about problems due to weird C++

5198 More portability fixes for problems summarized by Nelson H. F. Beebe.
5200 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
5201 than #include "...", and compile with -I'.'. The old method was
5202 not portable, according to Posix and the C standard, and it does
5203 not work with Sun C 5.7, where previous #line directives affect
5204 the working directory used in later #include "..." directives.

5215 '#include <map>' works and that you can apply ++ to iterators.
5217 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
5219 Work around portability problems summarized by Nelson H. F. Beebe in

5223 that '#include <string>' works.
5225 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
5226 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
5227 "warning: sorry: semantics of inline function static data `const
5228 unsigned char translate_table[262]' are wrong (you'll wind up with
5231 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
5232 or, xor to not_, and_, or_, and xor_, respectively. This works
5233 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
5234 random system header somewhere that includes the equivalent of

5238 -E" works; it apparently doesn't work with PathScale EKO Compiler
5241 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
5243 During deterministic GLR operation, user actions should be able to
5244 influence the parse by changing yychar. To make this easier to fix and
5245 to make glr.c easier to evolve in general, don't maintain yytoken in
5246 parallel with yychar; just compute yytoken when needed.
5247 * tests/glr-regression.at (Incorrect lookahead during deterministic
5248 GLR): Check that setting yychar in a user action has the intended
5250 * data/glr.c (yyGLRStack): Remove yytokenp member.
5251 (yyclearin): Don't set *yytokenp.
5252 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
5253 yychar rather than *yytokenp to determine the current lookahead.
5254 Compute yytoken locally when needed.
5255 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
5258 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
5259 after `--report' documentation.

5270 all the test at once. This makes the output easier to read in the
5273 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5274 got from <http://bro-ids.org/download.html>. The bug is that
5275 when two actions appeared in succession, the second one was
5276 scanned before the first one was added to the grammar rule
5277 as a midrule action. Bison then output the incorrect warning
5278 "parse.y:905.17-906.36: warning: unused value: $3".
5279 * src/parse-gram.y (BRACED_CODE, action): These are no longer
5280 associated with a value.
5281 (rhs): Don't invoke grammar_current_rule_action_append.
5282 (action): Invoke it here instead.
5283 * src/reader.c (grammar_midrule_action): Now extern.
5284 (grammar_current_rule_action_append): Don't invoke
5285 grammar_midrule_action; that is now the scanner's job.
5286 * src/reader.h (last_string, last_braced_code_loc):
5287 (grammar_midrule_action): New decls.
5288 * src/scan-gram.l (last_string): Now extern, sigh.
5289 (last_braced_code_loc): New extern variable.
5290 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
5291 rule already has an action.
5292 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
5293 * tests/input.at (AT_CHECK_UNUSED_VALUES):
5294 Add some tests to check that the above changes fixed the bug.
5296 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
5298 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
5299 All used changed. Check whether the symbol has a destructor,
5300 not whether it is typed.
5301 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
5302 that the values are still reported as unused. All line numbers

5316 Work around a bug in Pike 7.0, and give the Pike folks a
5317 better way to override the usual int widths.

5319 user can override the types.
5320 (short): #undef, to work around a bug in Pike 7.0.
5321 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
5322 (union yyalloc.yyss): Use yytype_int16 rather than short.
5324 (yysigned_char): Remove.
5325 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
5326 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
5327 * tests/regression.at (Web2c Actions): Adjust to above changes.
5329 * src/reader.c (check_and_convert_grammar): New function.

5349 since we don't want to insist on a version number at the start
5350 of the changelog every time.
5351 * Makefile.maint: Sync from coreutils a bit better.
5352 (sc_trailing_blank): Renamed from sc_trailing_space.
5354 (sc_no_if_have_config_h, sc_require_config_h):
5355 (sc_prohibit_assert_without_use): New rules.

5540 in the yychar entry.
5541 In the yychar entry, remove mention of the local yychar case (pure
5542 parser) since this is irrelevant information when writing semantic
5543 actions and since it's already discussed in `Table of Symbols' where
5544 yychar is otherwise described as an external variable.
5545 In the yychar entry, don't call it the `current' look-ahead since it
5546 isn't when semantic actions are deferred.
5547 In the yychar and yyclearin entries, add note about deferred semantic
5549 Add yylloc and yylval entries discussing look-ahead usage.
5550 (Look-Ahead Tokens): When discussing yychar, don't call it the

5575 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
5576 from which the RHS is taken. Set the lookahead members of the new

5579 yyaddDeferredAction.

5591 (Incorrect lookahead during nondeterministic GLR): New test case.
5593 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

5605 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
5607 * data/glr.c (yyresolveValue): When merging semantic options, if at
5608 least one user action succeeds but a later one cuts the parse, then
5609 destroy the semantic value before returning rather than leaking it.
5610 (yyresolveStates): If a user action cuts the parse and thus
5611 yyresolveValue fails, ignore the (unset) semantic value rather than
5612 corrupting the yyGLRState, and empty the semantic options list since
5613 the user actions should have called all necessary destructors.
5614 Simplify code with YYCHK.
5615 * tests/glr-regression.at (Corrupted semantic options if user action
5616 cuts parse): New test case.
5617 (Undesirable destructors if user action cuts parse): New test case.

5864 destroy the RHS symbols of a rule.
5865 * data/yacc.c (yylen): Initialize to 0.
5866 Keep its value to the number of items to possibly shift.
5867 In particular, a regular successful parse that ends on YYFINAL by
5868 a (internal) YYACCEPT must not have yylen != 0.
5869 (yyerrorlab, yyreturn): Pop the RHS.
5870 Reorder a bit to emphasize the `shifting' bits of code.
5871 (YYPOPSTACK): Now accept a number of items to pop.

5881 * djgpp/config.bat: Replace every occurence of the file name
5882 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
5883 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
5884 * djgpp/config.sed: Replace every occurence of the file name
5885 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

5891 using djunpack.bat and fnchange.lst.
5893 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
5895 * bootstrap (build_cvs_prefix): Remove; unused.
5896 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
5897 when getting gnulib.
5899 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>

5914 * tests/sets.at (Accept): Fix typos in regular expression used to
5915 sed out the final state number.
5917 Work around portability problem on Solaris 10: flex-generated
5918 files include <stdio.h> before <config.h>, which messes up
5919 because the latter defines __EXTENSIONS__. Address the problem
5920 by creating two new little files that include <config.h> first,
5921 then include the flex-generated files. Rewrite everyone else
5922 to include <config.h> first, as well.
5923 * lib/timevar.c: Always include "config.h".
5924 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

5963 Prepend /*ARGSUSED*/, for lint's sake.
5964 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
5965 definition if 'lint' is defined.
5966 (YYID): New macro (or function, if lint).
5967 All uses of /*CONSTCOND*/0 replaced by YYID(0).
5968 * data/yacc.c: Likewise.
5969 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
5970 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
5971 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
5973 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
5974 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
5975 Use YYID(0) rather than 0, for lint.
5976 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
5977 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

5997 * NEWS: Document the following change.
5998 * data/yacc.c: Say "parser skeleton" rather than "file", since
5999 it's no longer just a file.
6000 * data/glr.c: Grant a special exception for C GLR parsers, that
6001 reads like the already-existing exception for C LALR(1) parsers.
6002 * data/glr.cc: Likewise.
6003 * data/lalr1.cc: Likewise.
6004 * data/location.cc: Likewise.
6005 * data/yacc.c: Reword the "written by" statement to clarify that
6006 it was the parser skeleton, not the entire output file.

6014 Fix typos in previous change that broke 'make check'.
6015 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
6017 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
6018 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
6019 We can revert this once things settle down.
6021 * src/conflicts.c (conflicts_print): Don't print file name twice
6022 when %expect fails because there were no conflicts.
6023 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
6025 * tests/conflicts.at (%expect not enough, %expect too much):
6026 (%expect with reduce conflicts): Adjust to new behavior.

6095 Have glr.c include its header file when created.

6231 * data/yacc.c (YYMODERN_C): New macro, which also looks at

6262 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
6264 Undo the parts of the unlocked-I/O change that substituted
6265 putc or puts for printf. This might hurt performance a bit,
6266 but some people prefer the printf style.
6267 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
6268 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

6289 unused-variable warnings.
6291 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

6295 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
6297 Use unlocked I/O for a minor performance improvement on hosts like
6298 GNU/Linux and Solaris that support unlocked I/O. The basic idea
6299 is to use the gnlib unlocked-io module, and to prefer putc and
6300 puts to printf when either will work (since the latter doesn't
6301 come in an unlocked flavor).
6302 * bootstrap (gnulib_modules): Add unlocked-io.

6366 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
6368 * lib/subpipe.c: New function end_of_output_subpipe() added
6369 to allow support for non-posix systems. This is a no-op function
6372 * lib/subpipe.h: New function end_of_output_subpipe() added
6373 to allow support for non-posix systems. This is a no-op function
6376 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
6377 handle the lack of pipe/fork functionality on non-posix systems.

6445 (yysyntax_error_): Takes the state number as argument.
6446 (yyreduce_print_): Use the argument yyrule, not the former
6449 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>

6461 local variables whose names begin with 'yy'.
6462 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
6463 Trivial changes from Joel E. Denny.
6465 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
6467 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
6468 don't use alloca any more.
6470 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
6471 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
6472 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
6473 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
6474 to match yacc.c, to test more hosts.
6476 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
6478 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
6479 doesn't affect behavior.
6480 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
6482 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
6483 This works a bit better with glibc, if user code has already included
6485 * doc/bison.texinfo (Bison Parser): Document that users can't
6486 arbitrarily use malloc and free for other purposes. Document
6487 that <alloca.h> and <malloc.h> might be included.
6488 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
6489 user must declare alloca.

6498 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
6500 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
6501 (YYSTACK_ALLOC_MAXIMUM): Use it.
6502 (yysyntax_error): New function.
6503 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
6504 multiple syntax errors are reported, and alloca is being used.
6505 Instead, reallocate buffers twice as big each time, so that
6506 we waste at most half the allocated memory. Start with a small
6507 (128-byte) buffer that will suffice in most cases anyway.
6508 Use yysyntax_error to do most of the work.
6510 * doc/bison.texinfo (Error Reporting, Table of Symbols):
6511 yynerrs is the number of errors reported, not the number of
6514 * tests/glr-regression.at (Duplicated user destructor for lookahead):
6515 Mark it as expected to fail.
6516 Cast result of malloc; problem reported by twlevo@xs4all.nl.
6517 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
6518 Don't start user-code symbols with "yy", to avoid name space problems.
6520 2005-09-19 Akim Demaille <akim@epita.fr>
6522 Remove the traits, failed experiment.
6523 It never proved useful, and anyway because of the current
6524 definition, it was not possible to have several specialization of
6525 this traits, making it useless.
6526 * data/lalr1.cc (yy:traits): Remove.
6527 Inline its definitions in the parser class.
6529 2005-09-19 Akim Demaille <akim@epita.fr>

6551 * src/output.c (prepare): Likewise.
6552 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
6553 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
6554 is not defined. This is an awful hack, but it's enough for now.
6555 All callers changed.
6556 * tests/glr-regression-at (make_value): Args are const pointers now,
6557 to avoid GCC warning.
6558 (Duplicated user destructor for lookahead): New test. Currently
6559 skipped. It fails on my host but I'm not sure it'll always fail.
6561 2005-09-16 Akim Demaille <akim@epita.fr>
6563 * src/symtab.h (struct symbol): Declare the printer and destructor
6564 as const, to avoid accidental calls to free.
6565 (symbol_destructor_set, symbol_printer_set): Adjust.
6566 * src/symtab.c: Adjust.
6568 2005-09-16 Akim Demaille <akim@epita.fr>
6570 * data/c.m4 (b4_token_enums): New.
6571 (b4_token_defines): Rename as...
6572 (b4_token_enums_defines): this.
6573 (b4_token_defines): New, output only the #defines.
6574 * data/yacc.c, data/glr.c: Adjust.
6575 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
6576 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
6579 2005-09-16 Akim Demaille <akim@epita.fr>
6581 * data/lalr1.cc (yylex_): Remove, inline its code.
6582 (yyreport_syntax_error_): Remove, replaced by...
6583 (yysyntax_error_): this which returns a string and leaves to the
6584 caller the call to the users' error function.
6585 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
6586 Move from members of the parser object...
6587 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
6588 to local variables of the parse function.
6590 2005-09-16 Akim Demaille <akim@epita.fr>
6592 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
6593 since it's in Bison's name space.
6595 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
6597 * data/glr.c (yyresolveValue): Add default case to pacify
6598 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
6600 * NEWS: Document when yyparse started to return 2.
6601 * doc/bison.texinfo (Parser Function): Document when yyparse
6604 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
6605 (b4_filename_type): Renamed back from b4_file_name_type. All uses
6607 (class position): file_name -> filename (reverting). All uses changed.
6609 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
6611 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
6612 do anything if $@ exists. This reverts part of the 2005-07-07
6615 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
6617 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
6618 contains obsolete information and isn't worth distributing as a
6619 separate file anyway.
6620 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
6621 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
6622 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
6623 (yyparse): Abort if user code uses longjmp to throw an unexpected
6626 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
6628 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
6629 Suggested by twlevo@xs4all.nl.
6631 * data/glr.c (YYCHK1): Do not assume YYE is in range.
6632 This avoids a diagnostic from gcc -Wswitch-enum.
6633 Problem reported by twlevo@xs4all.nl.
6635 * doc/bison.texinfo: Don't use "filename", as per GNU coding
6636 standards. Use "file name" or "file" or "name", depending on
6638 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
6639 not to hack/foo.tab.c.
6640 (Calc++ Top Level): 2nd arg of main is not const.
6641 * data/glr.c: b4_filename -> b4_file_name.
6642 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
6644 (class position): filename -> file_name. All uses changed.

6653 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
6655 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
6656 to accommodate latest gnulib.

6659 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
6661 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
6664 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6666 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
6667 All uses changed. Invoke user destructor after an error during a
6668 split parse (trivial change from Joel E. Denny).
6670 * tests/glr-regression.at
6671 (User destructor after an error during a split parse): New test case.
6672 Problem reported by Joel E. Denny in:
6673 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
6675 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6677 * README-cvs: Give URLs for recommended tools.
6678 Mention Gzip version problem, and bootstrapping issues.
6679 Remove troubleshooting section, as it's somewhat obsolete.
6681 * bootstrap (no_cache): New var, to accommodate different wget
6682 variants. Use it instead of '-C off'. Problem reported by
6685 * data/glr.c (yydestroyStackItem): New function.
6686 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
6687 debugging information. Problem reported by Joel E. Denny.
6689 2005-08-25 Akim Demaille <akim@epita.fr>
6691 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
6693 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

6697 * tests/glr-regression.at
6698 (User destructor for unresolved GLR semantic value): New test case.
6699 Problem reported by Joel E. Denny in:
6700 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
6702 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
6704 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
6706 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
6707 lib-prefix.m4, po.m4.
6709 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
6710 in yydestruct diagnostic, since it might not be an error.
6711 Problem reported by Joel Denny near end of
6712 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6713 * data/lalr1.cc (yyerturn): Likewise.
6714 * data/yacc.c (yyreturn): Likewise.
6715 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
6717 * src/files.c: Remove obsolete FIXME comment.
6719 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
6720 with the other templates, and to fix bogus run-on messages such
6721 as the one reported at the end of
6722 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
6723 All callers changed to avoid the newline.
6724 (yyprocessOneStack): Output two lines rather than one, to accommodate
6725 the above change. This changes the debug output format slightly.
6727 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
6728 reported by Joel E. Denny in
6729 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
6731 * tests/glr-regression.at (Duplicate representation of merged trees):
6732 New test, from Joel E. Denny in:
6733 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
6734 * THANKS: Add Joel E. Denny.
6736 * configure.ac (AC_INIT): Bump to 2.0c.
6738 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
6740 * NEWS: Version 2.0b.
6742 * Makefile.am (SUBDIRS): Put examples before tests, so that
6743 "make check" doesn't finish with "All 1 tests passed".
6745 * tests/regression.at (Token definitions): Don't rely on
6746 AT_PARSER_CHECK for data that contains backslashes. It currently
6747 uses 'echo', and 'echo' isn't portable if its argument contains
6748 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
6749 that the byte '\0xff' is not printable in the C locale; it is,
6750 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
6751 not printable, so use '\0x81' to test.
6753 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
6754 version of GCC, since the macro is used with non-GCC compilers.
6756 Fix core dump reported by Pablo De Napoli in
6757 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
6758 * tests/regression.at (Invalid inputs with {}): New test.
6759 * src/parse-gram.y (token_name): Translate type before using
6762 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
6763 the user's name space. All uses changed to __attribute__
6765 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
6766 Add __attribute__ ((__noreturn__)).
6768 * etc/clcommit: Remove. We weren't using it, and it failed
6769 "make maintainer-distcheck".
6770 * Makefile.maint: Merge from coreutils.
6771 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
6772 (syntax-check-rules): Change list of rules as described below.
6773 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
6774 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
6775 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
6776 (sc_trailing_space): New rules.
6777 (sc_xalloc_h_in_src): Remove.
6778 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
6779 (sc_space_tab, sc_error_exit_success, sc_changelog):
6780 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
6781 (makefile-check, po-check, author_mark_check):
6782 (makefile_path_separator_check, copyright-check):
6783 Use grep -n, to make it easier to find violations.
6784 Use CVS_LIST and CVS_LIST_EXCEPT.
6785 (header_regexp, h_re): Remove.
6787 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
6788 (my-distcheck): Use more-modern GCC flags.
6789 (signatures, %.asc): Remove.
6790 (rel-files, announcement): Remove signatures.
6791 Restore old updating code, even though we don't use it, so
6792 that we're the same as coreutils.
6793 (alpha, beta, major): Depend on news-date-check.
6794 Make the upload commands.
6796 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
6797 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
6798 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
6799 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
6800 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
6801 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
6802 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
6803 * tests/sets.at: Likewise.
6805 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
6806 we comment out the Autoconf version number.
6807 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
6808 it's error-prone and "make maintainer-distcheck" rejects it.
6810 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
6811 Indent calls to "error" to pacify "make maintainer-distcheck",
6812 when the calls are not intended to be translated.
6813 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
6815 * src/Makefile.am (DEFS): Use +=, to pacify
6816 "make maintainer-distcheck".
6817 (bison_SOURCES): Add scan-skel.h.
6818 (sc_tight_scope): New rule, from coreutils.
6820 * src/files.c (src_extension, header_extension):
6821 Now static, not extern.
6822 * src/getargs.c (short_options): Likewise.
6823 * src/muscle_tab.c (muscle_table): Likewise.
6824 * src/parse-gram.y (current_class, current_type, current_prec):
6826 * src/reader.c (grammar_end, previous_rule_end): Likewise.
6827 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
6828 * src/main.c (main): Cast bindtextdomain and textdomain calls to
6829 void, to avoid warning when NLS is disabled.
6830 * src/output.c: Include scan-skel.h.
6831 (scan_skel): Remove decl, since scan-skel.h does this.
6833 Indent calls to "error" to pacify "make maintainer-distcheck".
6834 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
6835 * src/reader.h (gram_end, gram_lineno): New decls to pacify
6836 "make maintainer-distcheck".
6837 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
6838 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
6839 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
6840 (skel_lex_destroy, scan_skel): Move these decls to...
6841 * src/scan-skel.h: New file.
6842 * src/uniqstr.c (uniqstr_assert):
6843 Indent calls to "error" to pacify "make maintainer-distcheck".
6845 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
6848 * tests/torture.at: Revamp to avoid misuse of atoi that
6849 "make maintainer-distcheck" complained about.
6851 * examples/extexi (message): Don't print a message more than once,
6852 and omit line-number decoration that makes Emacs compile think
6853 that informative messages are worth worrying about.
6855 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
6857 * configure.ac: Update version number.
6859 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
6861 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
6862 autogenerated by the maintainer.
6863 * examples/calc++/.cvsignore: Add *.yy.
6865 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
6866 * lib/bitset_stats.c (bitset_stats_init): Likewise.
6867 * lib/bitsetv.c (bitsetv_alloc): Likewise.
6869 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
6871 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
6872 from maintainer-distcheck about casting the argument of 'free'.
6874 * NEWS: Mention recent yytname changes.
6875 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
6877 * bootstrap: For translations that have not yet been upgraded to
6878 the new runtime-po domain, prime the pump by extracting the
6879 relevant strings from the obsolete translations. This code can be
6880 removed once the bison-runtime domain has been translated by each
6883 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
6884 now that token names are already quoted.
6886 Fix problem reported by Anthony Heading.
6887 * data/glr.c (YYTOKEN_TABLE): New macro.
6888 (yytname): Define if YYTOKEN_TABLE.
6889 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
6890 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
6891 (YYERROR_VERBOSE): Define the same way the other skeletons do.
6892 * src/output.c (prepare_symbols): Output token_table_flag.
6894 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
6896 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
6897 again if the first call fails.
6899 * data/glr.c (yytnamerr): New function.
6900 (yyreportSyntaxError): Use it to dequote most string literals.
6901 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
6902 with other skeletons. All uses changed.
6903 (yytnameerr_): New function.
6904 (yyreport_syntax_error): Use it to dequote most string literals.
6905 * data/yacc.c (yytnamerr): New function.
6906 (yyerrlab): Use it to decode most string literals.
6907 * doc/bison.texinfo (Decl Summary, Calling Convention):
6908 Clarify quoting convention of yytname.
6909 * src/output.c (prepare_symbols): Quote all names. This undoes
6910 the 2005-04-17 change, which is now accomplished (mostly) via
6911 changes in the parsers as described above.
6912 * tests/regression.at (Token definitions, Web2c Actions):
6913 Undo most 2005-04-17 change here, too.
6915 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6917 Fix more problems reported by twlevo@xs4all.nl.
6918 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6919 remove trailing spaces. This loses the exit status of ./types,
6920 and isn't needed since ./types shouldn't be emitting trailing
6922 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6923 as the stack isn't valid in that case.
6925 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6926 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6927 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6928 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6930 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
6931 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6932 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6935 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6936 overly-picky compilers that reject 'char *foo = "bar";'.
6938 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6939 to FILE * parameter, not to stderr. This fixes a typo introduced
6940 in the 2005-07-12 change.
6942 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6943 warnings from GCC 4.
6945 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
6946 (yyglrShiftDefer, yysplitStack):
6947 Remove unused parameters b4_pure_formals. All uses changed.
6948 (yyglrShift): Remove unused parameters b4_user_formals.
6950 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
6952 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
6954 Destructor cleanups and regularization among the three skeletons.
6955 * NEWS: Document the behavior changes.
6956 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
6957 stack before failing, as the cleanup code will do it for us now.
6958 * data/lalr1.cc (yyerrlab): Likewise.
6959 * data/glr.c (yyparse): Pop everything off the stack before
6960 freeing it, so that destructors get called properly.
6961 * data/lalr1.cc (yyreturn): Likewise.
6962 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6963 This is more consistent.
6964 * doc/bison.texinfo (Destructor Decl): Mention more reasons
6965 why destructors might be called. 1.875 -> 2.1.
6966 (Destructor Decl, Decl Summary, Table of Symbols):
6967 Some English-language cleanups for %destructor.
6968 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6969 Add output line for destructor of start symbol.
6970 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
6971 because of that same extra output line.
6973 * NEWS: Document minor wording changes in diagnostics of
6974 Bison-generated parsers.
6975 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
6976 Remove unused formals. All uses changed.
6977 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
6978 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
6979 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6980 Rename yyoverflowab to yyexhaustedlab.
6981 When memory exhaustion occurs during syntax-error reporting,
6982 report it separately rather than in a single diagnostic; this
6984 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
6985 (Memory Exhausted): Renamed from Parser Stack Overflow.
6986 Revamp wording slightly to prefer "memory exhaustion".
6987 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
6989 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
6991 Add i18n support to the GLR skeleton. Partially fix the C++
6992 skeleton; a C++ expert needs to finish this. Remove debugging
6993 msgids; there's little point to having them translated, since they
6994 can be understood only by someone who can read the
6995 (English-language) source code.
6997 Generate runtime-po/bison-runtime.pot automatically, so that we
6998 don't have to worry about garbage getting in that file. We'll
6999 make sure after the next official release that old msgids don't
7001 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7003 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7005 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7006 Fix typos in explanations of the runtime file.
7007 * bootstrap: Change gettext keyword from YYI18N to YY_.
7008 Use standard Makefile.in.in in runtime-po, since we'll arrange
7009 for backward-compatible bison-runtime.po files in a different way.
7010 * data/glr.c (YY_): New macro, from yacc.c.
7011 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7012 Translate messages intended for users.
7013 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7014 the wording in the other skeletons. We don't know that the memory
7016 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7017 Use same method that yacc.c uses.
7018 Don't translate debugging messages.
7019 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7020 it doesn't work (yet), and requires C++ expertise to fix.
7021 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7022 Move defn to a more logical place, to be consistent with other
7024 Don't translate debugging messages.
7025 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7026 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7027 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7028 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7030 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7031 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7033 * tests/glr-regression.at (Badly Collapsed GLR States):
7035 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7036 yylex should return 0 at EOF rather than aborting.
7038 Improve tests for stack overflow in GLR parser.
7039 Problem reported by twlevo@xs4all.nl.
7040 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7042 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7043 can handle the problem.
7044 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7045 (yyparse): New local variable yyresult to record the result.
7046 Use result of setjmp to set it, rather than storing itinto
7048 (yyDone): Remove label.
7049 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7050 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7051 if YYABORT is used).
7052 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7053 yyparse status; put status > 1 into diagnostic.
7054 Check that status==2 works.
7055 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7056 Use exit status 3 for failure to open (which shouldn't happen).
7058 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7060 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7061 1 on syntax error; just let yyparse do its thing.
7062 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7063 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7064 (Exploding the Stack Size with Alloca):
7065 (Exploding the Stack Size with Malloc):
7066 Expect exit status 2, not 1, since the parser is supposed to blow
7067 its stack. Problem reported by twlevo@xs4all.nl.
7069 * data/glr.c (yyparse): Don't assume that the initial calls
7070 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7071 Print a stack-overflow message and fail instead.
7072 Initialize the line-number information before creating the stack,
7073 so that the stack-overflow message can report line zero safely.
7075 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7077 Fix problems reported by twlevo@xs4all.nl.
7078 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7079 (yyuserMerge): Provide a default case if b4_mergers is empty.
7080 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7081 * tests/glr-regression.at
7082 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7083 Add casts to pacify C++ compilers.
7084 * tests/glr-regression.at (Improper merging of GLR delayed action
7085 sets): Declare yylex before using it.
7086 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7087 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7088 test for valgrind; valgrind is independent of g++.
7089 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7090 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7091 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7092 Use a destructor, so that we can expand the stack. Change
7093 YYSTYPE to char * so that we can free it. Cast result of malloc.
7095 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7097 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7098 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7100 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7102 * PACKAGING: New file, suggested by Bruno Haible and taken from
7103 similar wording in gettext's PACKAGING file.
7104 * NEWS: Mention PACKAGING.
7105 * Makefile.am (EXTRA_DIST): Add PACKAGING.
7107 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
7109 * NEWS: Document recent i18n improvements.
7110 * bootstrap: Get runtime translations into runtime-po.
7111 Create runtime-po files automatically, if possible.
7112 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7113 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7114 does not infringe on the user's name space.
7115 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7116 * doc/bison.texinfo (Internationalization): Revamp the English
7117 and Texinfo syntax a bit, to try to make it clearer.
7118 (Bison Options, Option Cross Key): Mention --print-localedir.
7119 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7120 YYENABLE_NLS. Quote a bit more.
7121 * runtime-po/.cvsignore: New file.
7122 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
7123 * runtime-po/Rules-quot: Remove; now created by bootstrap.
7124 * runtime-po/quot.sed: Likewise.
7125 * runtime-po/boldquot.sed: Likewise.
7126 * runtime-po/en@quot.header: Likewise.
7127 * runtime-po/en@boldquot.header: Likewise.
7128 * runtime-po/insert-header.sin: Likewise.
7129 * runtime-po/remove-potcdate.sin: Likewise.
7130 * runtime-po/Makevars: Likewise.
7131 * runtime-po/LINGUAS: Likewise.
7132 * runtime-po/de.po: Likewise; we will rely on the translation project
7133 to maintain this, so "bootstrap" should get it.
7134 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7136 * src/main.c (main): Bind the bison-runtime domain, too.
7138 2005-07-12 Bruno Haible <bruno@clisp.org>
7140 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7141 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7142 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7143 * runtime-po: New directory.
7144 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7145 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7146 * runtime-po/Rules-quot: New file, copied from po/.
7147 * runtime-po/quot.sed: Likewise.
7148 * runtime-po/boldquot.sed: Likewise.
7149 * runtime-po/en@quot.header: Likewise.
7150 * runtime-po/en@boldquot.header: Likewise.
7151 * runtime-po/insert-header.sin: Likewise.
7152 * runtime-po/remove-potcdate.sin: Likewise.
7153 * runtime-po/Makevars: New file.
7154 * runtime-po/POTFILES.in: New file.
7155 * runtime-po/LINGUAS: New file.
7156 * runtime-po/bison-runtime.pot: New file.
7157 * runtime-po/de.po: New file.
7158 * m4/bison.m4: New file.
7159 * Makefile.am (SUBDIRS): Add runtime-po.
7160 (aclocaldir, aclocal_DATA): New variables.
7161 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7163 * src/getargs.c (usage): Document --print-localedir option.
7164 (PRINT_LOCALEDIR_OPTION): New enum item.
7165 (long_options): Add --print-localedir option.
7166 (getargs): Handle --print-localedir option.
7167 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7168 (Internationalization): New section.
7170 2005-07-12 Akim Demaille <akim@epita.fr>
7172 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7173 for consistency with the rest of the code.
7174 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7177 2005-07-12 Akim Demaille <akim@epita.fr>
7179 * src/parse-gram.y: Use %printer instead of YYPRINT.
7181 2005-07-12 Akim Demaille <akim@epita.fr>
7183 * src/symtab.h, src/symtab.c (symbol_print): New.
7184 * src/symlist.h, src/symlist.c (symbol_list_print): New.
7185 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
7187 2005-07-12 Akim Demaille <akim@epita.fr>
7189 * data/glr.c (b4_syncline): Fix (swap) the definitions of
7190 b4_at_dollar and b4_dollar_dollar.
7192 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
7194 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
7195 and Pennello's paper.
7197 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
7199 * data/yacc.c (yyparse): Undo previous patch. Instead,
7200 set yylsp[0] and yyvsp[0] only if the initial action
7201 sets yylloc and yylval, respectively.
7203 * data/yacc.c (yyparse): In the initial action, set
7204 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
7205 This avoids the use of undefined variables if the initial
7206 action does not set yylloc and/or yylval.
7208 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7210 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
7211 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
7212 Remove from CVS. These files are automatically generated.
7213 * examples/extexi: Clarify that this file is now part of Bison,
7214 not GNU M4, and that it works with any POSIX-compatible Awk.
7215 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
7216 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
7217 so that we also get calc++-parser.yy. Geneate it.
7218 Use $(AWK), not gawk, since any conforming Awk will do.
7219 Put comment before action, since older 'make' can't handle comment
7221 $(BUILT_SOURCES): List all built sources, not just some of them.
7222 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
7223 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
7224 $($(calc_sources_generated)): Remove unnecessary test for existence
7225 of target. (This had a shell syntax error anyway; a stray "x".)
7226 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
7228 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
7230 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
7231 implied by the other modules.
7233 2005-07-06 Akim Demaille <akim@epita.fr>
7235 Bind examples/calc++ to the package.
7236 * examples/calc++/Makefile: Remove, replaced by...
7237 * examples/calc++/Makefile.am: ... this new file.
7238 * examples/calc++/test: Remove input.
7239 * examples/calc++/compile: Remove.
7240 * examples/Makefile.am: New.
7241 * configure.ac, Makefile.am: Adjust.
7242 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
7244 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
7246 * data/glr.c (yyFail): Drastically simplify; since the format argument
7247 never had any % directives, we can simply pass it to yyerror.
7248 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
7249 be modified later, as that is the usual style in glr.c.
7250 Problems reported by Paul Hilfinger.
7252 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
7253 and size overflow errors.
7254 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
7255 in case the user prolog sets feature-test macros like _GNU_SOURCE.
7256 (YYSIZEMAX): New macro.
7257 (yystpcpy): New function, taken from yacc.c.
7258 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
7259 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
7260 so that we don't have to maintain their signatures.
7261 (yyFail): Check for buffer overflow, by using vsnprintf rather
7262 than vsprintf. Allocate a bigger buffer if possible.
7263 Report an error if buffer allocation fails.
7264 (yyStackOverflow): New function.
7265 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
7266 the initialization was successful. It might fail if storage was
7268 (yyexpandGLRStack): Add more checks for storage allocation failure.
7269 Use yyStackOverflow to report failures.
7270 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
7271 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
7272 Don't assume stack number fits in int.
7273 (yysplitStack): Check for storage allocation failure.
7274 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
7275 can print diagnostics on storage allocation failure. All callers
7277 (yyresolveValue): Use yybool for boolean.
7278 (yyreportSyntaxError): Check for size-calculation overflow.
7279 This code is taken from yacc.c.
7280 (yyparse): Check for storage allocation errors when allocating

7316 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
7317 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
7318 which stems from the 2005-05-27 patch.
7320 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
7322 * data/glr.c: Modify treatment of unused parameters to permit use
7323 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).

7337 Fix infringement on user name space reported by Bruno Haible.
7338 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
7339 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
7340 the user's name space.
7341 (alloca): Include <stdlib.h> to get it, if it's not built in.
7342 (YYMALLOC, YYFREE): Define only if needed.
7343 (malloc, free): Declare, but only if needed, as this infringes on
7344 the user name space.
7346 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7348 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
7349 * lib/bitset.c (bitset_print): Don't assume size_t can be printed

7364 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
7366 * bootstrap: Remove workaround for problem I encountered with
7367 gettext 0.14.1; it seems to be fixed now.

7371 * NEWS: Version 2.0a.
7373 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
7374 the previous change.
7376 Various maintainer cleanups.
7377 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7378 conftest*, for benefit of CVS commands run at the same time as
7379 "configure". Add build-aux, since "bootstrap" now creates it and
7381 * Makefile.cfg (move_if_change): Remove.
7382 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7383 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

7390 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
7391 this is now the recommended name.
7392 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
7393 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
7394 ylwrap. These files now go into build-aux.
7395 * config/move-if-change: Remove.
7396 * config/prev-version.txt: Bump from 1.75 to 2.0.
7398 * bootstrap: Add stdio-safer, unistd-safer modules.

7402 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7403 * lib/subpipe.c: Include "unistd-safer.h".
7404 (create_subpipe): Make sure all the newly-created
7405 file descriptors are > 2, so that diagnostics don't
7406 get sent down them (which might cause Bison to hang, in theory).
7407 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
7408 * src/files.c (xfopen): Use fopen_safer, not fopen.
7410 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
7411 yesterday's yacc.c fix.
7413 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

7419 * data/yacc.c (yyabortlab): Don't call destructor, and
7420 don't set yychar to EMPTY.
7421 (yyoverflowlab): Don't call destructor.
7422 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
7423 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
7424 since we no longer output the message "discarding lookahead token
7427 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7429 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
7430 fix a small glitch in debugging output.
7431 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
7432 after YY_SYMBOL_PRINT where needed.

7486 Problem reported by Ralf Menzel.
7488 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7490 * tests/actions.at: Test that stack overflow invokes destructors.
7491 From Marcus Holland-Moritz.
7492 * data/yacc.c (yyerrlab): Move the code that destroys the stack
7494 (yyreturn): to here. That way, destructors are called properly
7495 even if the stack overflows, or the user calls YYACCEPT or
7496 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
7497 (yyoverflowlab): Destroy the lookahead.
7499 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
7501 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
7503 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
7505 * NEWS: Bison-generated C parsers no longer quote literal strings
7506 associated with tokens.
7507 * src/output.c (prepare_symbols): Don't escape strings,
7508 since users don't want to see C escapes.
7509 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
7511 * tests/input.at (Torturing the Scanner): Likewise.
7512 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
7514 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
7516 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
7517 the data size is known to be too small and we can't increase it.
7518 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
7520 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
7522 * src/parse-gram.y: Include quotearg.h.
7523 (string_as_id): Quote $1 before using it as a key, since the
7524 lexer no longer quotes it for us.
7525 (string_content): Don't strip quotes, since lexer no longer
7527 * src/scan-gram.l: Include quotearg.h.
7529 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
7530 a key, since the rest of the lexer doesn't quote it.
7531 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
7532 * tests/regression.at (Token definitions): Check for backslashes
7535 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
7536 (YYSIZE_T): Define to unsigned long int when using an older compiler.
7537 (yyparse): Revamp code to generate long syntax error message, to
7538 make it easier to translate, and to avoid problems with arithmetic
7539 overflow. Change "virtual memory" to "memory" in diagnostic, since
7540 we don't know whether the memory is virtual.
7542 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7544 * NEWS: Bison-generated C parsers now use the _ macro to
7546 * data/yacc.c (_) [!defined _]: New macro.
7547 All English strings wrapped inside this macro.
7548 * doc/bison.texinfo (Bison Parser): Document _.
7549 * po/POTFILES.in: Include src/parse-gram.c, since it now
7550 includes translateable strings that parse-gram.y doesn't.
7552 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
7554 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
7555 reverting the 2004-10-11 change to this function.
7556 (symbol_check_alias_consistency): Don't call symbol_type_set
7557 if the type name is already correct.
7558 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
7560 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
7562 * tests/regression.at (Token definitions): Don't use a token named
7563 c, as that generates a "#define c ..." that runs afoul of buggy
7564 stdlib.h that uses the identifier c as a member of struct
7565 drand48_data. Problem reported by Horst Wente.
7567 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
7569 * bootstrap: Change translation URL from
7570 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
7571 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
7572 redirection glitches. Problem reported by twlevo@xs4all.nl.
7574 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
7576 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
7577 after operands; POSIX says this isn't portable for the c99 command.
7579 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
7581 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
7582 immediately if a data overrun has occurred; this may help us track
7583 down what may be a spurious failure on MacOS.
7585 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
7587 Respond to problems reported by twlevo@xs4all.nl.

7600 "#if 0", since it's not currently used. Problem reported by
7603 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
7605 * src/output.c (escaped_output): Renamed from
7606 escaped_file_name_output, since we now use it for symbol tags as
7607 well. All uses changed.
7608 (symbol_destructors_output, symbol_printers_output):
7609 Escape symbol tags too.
7610 Problem reported by Matyas Forstner in
7611 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
7613 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
7615 * src/output.c (user_actions_output, token_definitions_output,
7616 symbol_destructors_output, symbol_printers_output): Likewise.
7617 * src/reader.c (prologue_augment): Likewise.
7618 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
7620 * src/vcg.c (output_edge): Don't quote linestyle arg.
7621 Problem reported by twlevo@xs4all.nl.
7623 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
7625 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
7626 example, reported by Derek M Jones. Also, make the example even
7627 more outrageous, to better illustrate how bad the problem is.
7629 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
7631 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
7632 putsym. Typo reported by Sebastian Piping.
7634 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7636 * doc/bison.texinfo (Language and Grammar): some -> same
7637 (Epilogue): int he -> in the
7638 Typos reported by Sebastian Piping via Justin Pence.
7640 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7642 * tests/glr-regression.at (Improper handling of embedded actions
7643 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
7644 embedded actions and $-N in GLR parsers", work around an Autoconf bug
7645 with dollar signs in test names.
7646 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
7647 for a similar reason.
7649 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7651 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
7652 wants to redefine G_VIEW.
7654 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
7656 * src/vcg.c (get_view_str): Remove case for normal_view.

7662 Problem reported by twlevo@xs4all.nl.
7664 * doc/bison.texinfo: Change @dircategory from "GNU programming
7665 tools" to "Software development". Requested by Richard Stallman
7668 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
7670 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
7671 Problem reported by twlevo@xs4all.nl.
7673 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
7675 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
7676 keyword; it's not needed with modern compilers, and it doesn't
7677 affect correctness with older compilers. Suggested by
7680 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
7682 * data/glr.c (yyuserAction): Add "default: break;" case to pacify

7692 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
7694 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
7695 for the benefit of slower hosts. Problem reported by
7698 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
7700 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
7701 being defined and not used.
7702 * data/lalr1.cc (yyparse): Likewise.
7703 Use "if (false)" rather than "if (0)".

7707 * TODO: Mention that we should allow NUL bytes in tokens.
7709 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
7711 * src/scan-skel.l (<<EOF>>): Don't close standard output.
7712 Problem reported by Hans Aberg.
7714 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
7716 * src/getargs.c (version): Happy new year; update overall
7717 program copyright date from 2004 to 2005.
7719 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
7720 Problem reported by Hans Aberg.
7721 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
7722 (Output file names.): Add a test for the case when standard output
7725 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
7727 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
7728 to fix an oversight in the Bison 2.0 manual.
7730 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
7732 * NEWS: Version 2.0. Reformat the existing news items since
7733 1.875, so that related items are grouped together.
7734 * configure.ac (AC_INIT): Bump version to 2.0.
7735 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
7737 * tests/torture.at (Exploding the Stack Size with Alloca): Set
7738 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
7739 otherwise, we're not testing alloca. Unfortunately there's no
7740 simple way to consult HAVE_ALLOCA here.
7742 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
7745 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
7746 hand. This avoids a warning about comparing int to size_t when
7747 GCC warnings are enabled.
7749 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
7751 * NEWS: Bison-generated parsers no longer default to using the
7752 alloca function (when available) to extend the parser stack, due
7753 to widespread problems in unchecked stack-overflow detection.
7754 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
7755 responsibility to set it to a positive value. This lets the user
7756 specify a value that is not a preprocessor constant.
7757 * data/yacc.c (YYMAXDEPTH): Likewise.
7758 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
7759 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
7760 to be a compile-time constant. However, explain the constraints on it.
7761 Also, explain the constraints on YYINITDEPTH.
7762 (Table of Symbols): Explain that alloca is no longer the default.
7763 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
7766 * doc/bison.texinfo (Location Default Action): Mention that n must
7767 be zero when k is zero. Suggested by Frank Heckenbach.
7769 2004-12-22 Akim Demaille <akim@epita.fr>
7771 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
7772 (parser::state_type, parser::semantic_type, parser::location_type):
7773 Private, not public.
7774 (parser::parse): Return ints, not bool.
7775 Returning a bool introduces a problem: 0 corresponds to false, and
7776 it seems weird to return false on success. Returning true changes
7777 the conventions for yyparse.
7778 Alternatively we could return void and send an exception.
7779 There is no clear consensus (yet?).
7780 (state_stack, semantic_stack, location_stack): Rename as...
7781 (state_stack_type, semantic_stack_type, location_stack_type): these.
7782 Private, not public.
7783 * tests/c++.at: New.
7784 * tests/testsuite.at, tests/Makefile.am: Adjust.
7786 2004-12-21 Akim Demaille <akim@epita.fr>
7788 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
7790 2004-12-21 Akim Demaille <akim@epita.fr>
7792 Don't impose std::string for filenames.
7794 * data/lalr1.cc (b4_filename_type): New.
7795 (position::filename): Use it.
7796 (parser.hh): Move the inclusion of stack.hh and location.hh below
7797 the user code, so that needed headers for the filename type can be
7799 Forward declare them before the user code.
7800 * tests/Makefile.am (check-local, installcheck-local): Pass
7801 TESTSUITEFLAGS to the TESTSUITE.
7803 2004-12-20 Akim Demaille <akim@epita.fr>
7805 Use more STL like names: my_class instead of MyClass.
7807 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
7808 (SemanticStack, SemanticType, StateStack, StateType)
7809 (TokenNumberType, Stack, Slice, Traits, Parser::location)
7810 (Parser::value): Rename as...
7811 (location_stack, location_type, rhs_number_type, semantic_stack)
7812 (semantic_type, state_stack, state_type, token_number_type, stack)
7813 (slice, traits, parser::yylloc, parser::yylval): these.
7815 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
7817 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
7819 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
7820 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
7822 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
7824 Remove uses of 'short int' and 'unsigned short int'. This raises
7825 some arbitrary limits. It uses more memory but nowadays that's
7826 not much of an issue.
7828 This change does not affect the generated parsers; that's a different
7829 task, as some users will want to conserve memory there.
7831 Ideally we should use size_t to represent all object counts, and
7832 something like ptrdiff_t to represent signed differences of object
7833 counts; but that will require more code-cleanup than I have the
7834 time to do right now.
7836 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
7837 Use size_t, not int or short int, to count objects.
7838 * src/closure.c (nritemset, closure): Likewise.
7839 * src/closure.h (nritemset, closure): Likewise.

7850 errs, reductions): Likewise.

7853 * src/tables.c (vector_number, tally, action_number,
7854 ACTION_NUMBER_MINIMUM): Likewise.
7855 * src/output.c (muscle_insert_short_int_table): Remove.
7857 2004-12-17 Akim Demaille <akim@epita.fr>
7859 * data/lalr1.cc: Extensive Doxygenation.
7860 (error_): Rename as...
7861 (error): this, since it is visible to the user.
7863 (Parser::message): Now an automatic variable from...
7864 (Parser::yyreport_syntax_error_): here.
7865 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
7867 * tests/input.at: Escape $.
7869 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
7871 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
7872 Parenthesize rhs to avoid obscure problems with mistakes like
7873 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
7874 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7875 b4_rhs_location): Likewise.
7876 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
7877 b4_rhs_location): Likewise.
7879 2004-12-16 Akim Demaille <akim@epita.fr>
7881 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
7882 yacc.c: be sure to stay within yycheck_.
7883 * tests/actions.at: Re-enable C++ tests.
7885 2004-12-16 Akim Demaille <akim@epita.fr>
7887 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
7890 2004-12-16 Akim Demaille <akim@epita.fr>
7892 Use #define to handle the %name-prefix.
7894 * data/glr.c, data/yacc.c: Comment changes.
7895 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
7896 so that one can refer to yylex in the parser file, and have it
7897 renamed, as is the case with other skeletons.
7899 2004-12-16 Akim Demaille <akim@epita.fr>

7921 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
7923 Fix some problems reported by twlevo at xs4all.
7924 * src/symtab.c (symbol_new): Report an error if the input grammar
7925 contains too many symbols. This is better than calling abort() later.
7926 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
7927 (struct node, struct graph):
7928 Rename member expand to stretch. All uses changed.
7929 (struct graph): Remove member layoutalgorithm. All uses removed.

7944 2004-12-15 Akim Demaille <akim@epita.fr>
7946 * data/lalr1.cc (lex_): Rename as...
7948 Move the trace here.
7949 Take the %name-prefix into account.
7950 Reported by Alexandre Duret-Lutz.
7952 2004-12-15 Akim Demaille <akim@epita.fr>
7954 Simplify the C++ parser constructor.
7956 * data/lalr1.cc (debug_): Rename as...
7957 (yydebug_): so that the parser's internals are always in the yy*
7960 (b4_parse_param_decl): Remove the leading comma as it is now only
7961 called as unique argument list.
7962 (Parser::Parser): Remove the constructor accepting a location and
7963 an initial debugging level.
7964 Remove from the other ctor the argument for the debugging level.
7965 (debug_level_type, debug_level, set_debug_level): New.
7967 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
7970 2004-12-15 Akim Demaille <akim@epita.fr>
7972 Remove b4_root related material: failure experiment
7973 (which goal was to allow to derive from a class).
7975 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
7976 definitions and uses.
7978 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
7980 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
7981 not 2, since it's not portable to subtract 1 from the start of an
7982 array. The new item 0 is never set or used. All uses changed.
7984 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
7985 the default definition of YYLLOC_DEFAULT. Problem reported
7986 by Frank Heckenbach.
7988 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
7990 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
7991 the normal case and one for the error case. Just use the
7992 first one uniformly. Problem reported by Frank Heckenbach.
7993 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
7994 use exactly the same macro in both places.
7995 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
7996 so that the normal-case YYRHSLOC works for the error case too.
7998 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
7999 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8000 * doc/bison.texinfo (Location Default Action): Don't claim that
8001 we have an array of locations. Use the same macro for both glr
8002 and lalr parsers. Mention YYRHSLOC. Mention what happens when

8014 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
8016 * src/scan-skel.l: Include "complain.h", for "fatal".
8018 * src/relation.h (relation_print, relation_digraph):
8019 Relation sizes are of type relation_node, not size_t (this is
8020 merely a doc fix, since the two types are equivalent).
8021 (relation_transpose): Relation sizes are of type relation_node,
8023 * src/relation.c: Likewise.
8024 (top, infinity): Now of type relation_node, not int.
8025 (traverse, relation_transpose): Use relation_node, not int.
8027 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8028 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8029 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8031 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8032 specifying whether the test should be skipped. Use it tp
8033 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8034 fail on some hosts, and should be skipped.
8036 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8038 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8039 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8040 unless otherwise specified below.
8042 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8043 to allocate kernel_base, kernel_items, kernel_size, since
8044 they needn't be initialized to 0.
8045 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8046 * src/closure.c (new_closure): Likewise, for itemset.

8062 (goto_actions): Likewise for state_count.
8063 (pack_table): Likewise for base, pos, check.
8064 (tables_generate): Likewise for width.
8066 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8067 for initial core. Just have a separate core, so we needn't worry
8068 about whether kernel_size and kernel_base are initialized.
8070 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8071 kernel_size, kernel_items): Remove unnecessary initialization.

8077 conflrow, conflict_table, conflict_list, table, check):
8080 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8081 This is because all callers pass unsigned int.
8082 * src/closure.h (new_closure): Likewise.
8084 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8085 (build_relations): Initialize includes[i] in all cases.

8087 and rules[ruleno].precsym. Initialize members in order.

8090 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8092 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8093 conflict_list[0] was always 0, but now it isn't initialized.
8095 * src/table.c (table_grow): When conflict_table grew, the grown
8096 area wasn't cleared. Fix this.
8098 * lib/.cvsignore: Add strdup.c, strdup.h.

8101 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8103 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8104 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8105 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8106 ngotos + 1 without checking for overflow.
8107 (build_relations): Use END_NODE, not -1, to denote end of edges.
8108 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8109 build_relations): Use goto_number, not int, for goto numbers.

8114 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8115 of #defining from yystype.
8116 Don't typedef yystype, C++ does not need it.
8117 This lets it possible to forward declare it as union.
8119 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8121 * bootstrap (gnulib_modules): Add extensions.
8122 Problem reported by Jim Meyering.

8168 have an accurate range, equivalent to the one computed by both
8169 yacc.c and lalr1.cc.
8170 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8171 that column numbers start at column 0, as per GNU Coding
8172 Standards, the others tests, and the doc.
8173 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8174 Adjust to the above change (first column is 0).

8181 Remove some arbitrary limits on goto numbers and relations.
8182 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
8183 initial values, since they're never used.
8184 (set_goto_map): ngotos is now unsigned, so test for overflow
8185 by seeing whether it wraps around to zero.
8186 * src/lalr.h (goto_number): Now size_t, not short int.
8187 (GOTO_NUMBER_MAXIMUM): Remove.
8188 * src/relation.c (relation_print, traverse, relation_transpose):
8189 Check for END_NODE rather than looking at sign.
8190 * src/relation.h (END_NODE): New macro.
8191 (relation_node): Now size_t, not short int.
8193 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
8195 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
8196 keyword, not an identifier. Problem reported by Baron Schwartz in
8197 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
8199 2004-10-11 Akim Demaille <akim@epita.fr>
8201 * src/symtab.c (symbol_check_alias_consistency): Also check
8202 type names, destructors, and printers.
8203 Reported by Alexandre Duret-Lutz.
8204 Recode the handling of associativity and precedence in terms
8205 of symbol_precedence_set.
8206 Accept no redeclaration at all, not even equal to the previous
8208 (redeclaration): New.
8209 Use it to factor redeclaration complaints.
8210 (symbol_make_alias): Don't set the type of the alias, let
8211 symbol_check_alias_consistency do it as for other features.
8212 * src/symtab.h (symbol): Add new member prec_location, and
8214 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
8215 * tests/input.at (Incompatible Aliases): New.
8217 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
8219 .cvsignore fixes to accommodate gnulib changes,
8220 and the practice of naming build directories "_build".
8221 * .cvsignore: Add "_*". Sort.
8222 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
8223 * m4/.cvsignore: Add "*_gl.m4".
8225 2004-10-06 Akim Demaille <akim@epita.fr>
8227 * src/parse-gram.y (add_param): Fix the truncation of trailing
8230 2004-10-05 Akim Demaille <akim@epita.fr>
8232 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8233 whether the reducion was empty or not. This leaves room to
8234 improve the use of YYLLOC_DEFAULT in such a case.
8235 lalr1.cc is still experimental, so changing this is acceptable.
8236 And finally, there are probably not many users who changed the
8237 handling of locations in GLR, so changing is admissible too.
8239 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8240 empty reduction, set @$ to an empty location ending the previously
8242 Adjust uses to make sure the code is triggered on empty
8244 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8245 expected output: empty reductions have empty locations.
8247 2004-09-29 Akim Demaille <akim@epita.fr>
8249 * data/lalr1.cc: Move towards a more standard C++ coding style
8250 for templates: Class < T > -> Class<T>.
8252 2004-09-29 Akim Demaille <akim@epita.fr>
8254 * data/lalr1.cc: Reinstall the former ctor, for sake of
8255 compatibility, but warn it will be removed.
8256 Move towards a more standard C++ coding style (i.e., type *var ->
8259 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
8261 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
8262 since it's less likely to work if NULs are involved in the future.
8264 2004-09-27 Akim Demaille <akim@epita.fr>
8266 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
8268 2004-09-27 Akim Demaille <akim@epita.fr>
8270 * data/lalr1.cc (b4_parse_param_decl_1): New.
8271 (b4_parse_param_decl): Use it to have different names between attribute
8273 (b4_cc_constructor_call): Likewise.
8275 2004-09-24 Akim Demaille <akim@epita.fr>
8277 * src/parse-gram.y (add_param): Strip the leading and trailing
8278 blanks from a formal argument declaration.
8279 (YY_LOCATION_PRINT): New.
8281 2004-09-24 Akim Demaille <akim@epita.fr>
8283 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
8286 2004-09-24 Akim Demaille <akim@epita.fr>
8288 * doc/bison.texinfo (Table of Symbols): Sort.
8290 2004-09-21 Akim Demaille <akim@epita.fr>
8292 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
8293 the useless parentheses.
8294 Suggested by Paul Eggert.
8296 2004-09-20 Akim Demaille <akim@epita.fr>
8298 Let the initial-action act on the look-ahead, and use it for the
8299 "initial push" (corresponding to an hypothetical beginning-of-file).
8300 And let lalr1.cc honor %initial-action.
8302 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
8304 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
8305 (Parser::Parser): Remove the ctor that used to initialize it.
8306 (Parser::parse): Like in the other skeletons, issue the "starting
8307 parse" message before any action.
8308 Honor %initial-action.
8309 Initialize the stacks with the lookahead.
8310 * data/yacc.c: Let $$ and @$ in %initial-action designate the
8312 Push them in the stacks.
8313 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
8315 2004-09-20 Akim Demaille <akim@epita.fr>
8317 * doc/bison.texinfo (Initial Action Decl): New.
8319 2004-09-20 Akim Demaille <akim@epita.fr>
8321 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
8322 clearer criterion to define it.
8323 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
8324 When reducing on an empty RHS, use the latest stacked location as
8326 yylloc is not always available.
8327 * data/glr.c: Likewise.
8328 Also, honor initial-actions.
8330 2004-09-20 Akim Demaille <akim@epita.fr>
8332 * data/yacc.c (YY_LOCATION_PRINT): New.
8333 Define when we know YYLTYPE's structure, i.e., when the default
8334 YYLLOC_DEFAULT is used.
8335 * data/c.m4 (b4_yysymprint_generate): Use it.
8336 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
8337 value of the result.
8338 (error_start_): Replace with...
8339 (error_range_): this location array.
8340 This allows to replace code relying on the implementation of
8341 locations by portable code.
8342 * data/yacc.c (yylerrsp): Replace with...
8343 (yyerror_range): this.
8344 Every time a token is popped, update yyerror_range[0], to have an
8345 accurate location for the error token.
8346 * data/glr.c (YY_LOCATION_PRINT): New.
8347 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
8348 deference a pointer.
8349 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
8350 report the location in %printers.
8352 * src/scan-skel.l: Instead of abort, report error messages to ease
8353 understanding skeleton scanning failures.
8355 2004-09-16 Akim Demaille <akim@epita.fr>
8357 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
8358 (iterator, const_iterator): these, to be more in the C++ spirit.
8359 Also, return reverse iterators so that when displaying the stack
8360 we display its bottom first.
8361 (Parser::stack_print_, Parser::reduce_print_): Match the messages
8363 We should probably use vector here though.
8365 2004-09-16 Akim Demaille <akim@epita.fr>
8367 Have more complete shift traces.
8369 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
8370 to report Shifts instead of ad hoc YYDPRINTF invocations,
8371 including for the error token.
8372 * data/lalr1.cc (symprint_): Output the location.
8373 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
8374 output the location within the %printer.
8375 Activate GLR tests, at least to make sure they compile properly.
8376 They still don't pass though.
8377 * tests/calc.at: Adjust expect verbose output, since now "Entering
8378 state..." is on a different line than the "Shifting" message.
8380 2004-09-08 Akim Demaille <akim@epita.fr>
8382 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
8383 Bison directive from the Bison file to the invocation of this
8384 macro, so that these directives are passed to
8385 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8386 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8387 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8388 the extra Bison directives instead of the whole series.
8389 Change the grammar so that there are recoverable errors, and
8390 unrecoverable errors. Now we can have the parser give up before
8391 consuming the whole input. As a result we now can observe that
8392 the lookahead is freed when needed.
8393 Change the parser source to parse argv[1] instead of a hard coded
8395 Simplify yylex, and give a value and location to EOF.
8396 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8397 passed directives already coded in the file.
8398 Add some tests to check the location of "error".
8399 For some tests, the C++ parser is correct, and not yacc.c.
8400 For other tests, they provide different, but unsatisfying, values,
8401 so keep the C++ value so that at least one parser is "correct"
8402 according to the test suite.
8403 (Actions after errors): Remove, this is subsumed by the
8404 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
8406 2004-09-06 Akim Demaille <akim@epita.fr>
8408 * data/lalr1.cc: Adjust the indentation of the labels.
8412 2004-09-06 Akim Demaille <akim@epita.fr>
8414 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
8415 argument, an informative message.
8416 Call YY_SYMBOL_PRINT.
8417 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
8418 * data/lalr1.cc (destruct_): Likewise.
8419 In addition, no longer depend on b4_yysymprint_generate and
8420 b4_yydestruct_generate to generate these functions, do it "by
8423 2004-09-03 Akim Demaille <akim@epita.fr>
8425 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
8426 invoked, yydestruct the lookahead.
8427 * tests/calc.at (Calculator $1): Update the expected lengths of
8428 traces: there is an added line for the discarded lookahead.
8429 * doc/bison.texinfo (Destructor Decl): Some rewording.
8430 Define "discarded" symbols.
8432 2004-09-02 Akim Demaille <akim@epita.fr>
8434 * data/lalr1.cc (translate_, destruct_): No reason to be static.
8436 2004-09-02 Akim Demaille <akim@epita.fr>
8438 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
8439 (YYDSYMPRINTF): Rename as...
8440 (YY_SYMBOL_PRINT): this.
8441 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
8443 Use it instead of direct symprint_ calls.
8444 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
8447 2004-09-02 Akim Demaille <akim@epita.fr>
8449 * data/lalr1.cc (b4_yysymprint_generate): New.
8450 (symprint_): New member function, defined when YYDEBUG.
8451 Use it consistently instead of token/nterm debugging output by
8453 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
8454 %printer calls to use cdebug_ when using lalr1.cc.
8456 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
8458 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
8459 with #ifdef YYDEBUG.
8461 2004-08-26 Akim Demaille <akim@epita.fr>
8463 * doc/bison.texinfo (Implementing Loops): Rename as...
8464 (Implementing Gotos/Loops): this.
8466 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
8468 Adjust to latest gnulib.
8469 * bootstrap (gnulib_modules): Add xalloc-die.
8470 Set LC_ALL=C so that file names sort consistently.
8471 Prefer the gnulib copies of gettext.m4, glibc21.m4,
8472 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
8473 uintmax_t.m4, ulonglong.m4.
8474 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
8475 po.m4 since we are now using _gl.m4 instead.
8477 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
8479 * src/scan-action.l: Remove. Scanning of semantic actions is
8480 handled in scan-gram.l.
8482 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
8484 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
8486 * src/location.h (struct): The file member is a uniqstr.
8487 (equal_boundaries): Use UNIQSTR_EQ for comparison.
8489 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
8491 Fix bug with non-%union parsers that have printers or destructors,
8492 which led to a Bison core dump. Reported by Peter Fales in
8493 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
8495 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
8496 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
8497 not to our own type.
8498 * src/output.c (symbol_destructors_output, symbol_printers_output):
8499 Don't assume %union.
8500 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
8501 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
8502 UNION-FLAG. All callers changed.
8503 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
8504 Use type char, not unsigned int, when declaring an array of char;
8505 this lets us remove a cast.
8506 (Printers and Destructors): Add non-%union test cases.
8508 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8510 * doc/bison.texinfo: Minor editorial changes, mostly to the new
8511 GLR writeups. E.g., avoid frenchspacing and the future tense,
8512 change "lookahead" to "look-ahead", and change "wrt" to "with
8515 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8517 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
8518 New sections, split off from the GLR Parsers section. Put the new
8519 Simple GLR Parser near the start of the GLR section, for clarity.
8520 Rewrite connective text.
8522 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
8524 * doc/bison.texinfo (Simple GLR Parsers): New section.
8526 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
8528 * NEWS, TODO, doc/bison.texinfo:
8529 Use "look-ahead" instead of "lookahead", to be consistent.
8530 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
8531 while we're fixing "look-ahead".
8532 * src/conflicts.c (shift_set): Renamed from shiftset.
8533 (look_ahead_set): Renamed from lookaheadset.
8534 * src/print.c: Likewise.

8553 * README: Update location of patched M4 distribution.
8555 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
8557 Don't assume the C++ compiler takes the same arguments as the C compiler
8559 * configure.ac (O0CXXFLAGS): New var.
8560 * tests/atlocal.in (CXXFLAGS): Use it.
8562 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
8564 Fix some "make check" problems with C++ reported by
8565 Albert Chin-A-Young for Tru64 C++ in this thread:
8566 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
8568 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
8569 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8570 Output to a .cc file for C++, not to a .c file.

8575 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
8577 * tests/calc.at, tests/actions.at: Workaround for SGI
8578 C++ compiler. (trivial change)
8580 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
8582 Spent a few hours checking out which prerequisite versions the
8583 current sources actually require. I went all the way back to
8584 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8585 a seemingly endless set of combinations of versions more recent
8586 than that. The bottom line is that the current sources require
8587 fairly recent versions of the build tools, and it'll be some work
8589 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
8590 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
8591 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
8592 Add comments explaining why those particular versions are
8595 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
8596 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
8597 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
8599 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
8600 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
8602 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8604 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
8605 0.11.5. Suggested by Bruno Haible.
8606 * bootstrap: Remove gettext version checking.
8608 * doc/bison.texinfo (Decl Summary): Also mention that %union
8609 can depend on prerequisite types. Problem reported by Tim
8612 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8614 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
8615 * README-alpha: Don't tell people not to package this.
8617 * bootstrap: Don't assume $(...) works; use `...` instead.
8618 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
8621 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
8622 put into the -d output file, and mention what to do if YYSTYPE is
8625 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8627 Undo change made earlier today: it caused autopoint to not bring
8628 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
8631 * bootstrap: Check that gettext version matches what's in
8632 configure.ac. Warn users to ignore robots.txt ERROR 404.
8633 * bootstrap: Undo today's earlier change (logged below).
8634 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
8636 The gettext version checking is causing more trouble than it's
8637 curing; remove it. Problem reported by Paul Hilfinger.
8639 * bootstrap: Issue a warning that one can expect a message
8640 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
8641 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
8643 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
8645 Ensure that the C++ compiler used for testing actually works on a
8646 simple test program; if not, skip the C++-related tests. Problem
8647 reported by Vin Shelton in:
8648 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
8650 * m4/cxx.m4: New file.
8651 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
8652 * tests/atlocal.in (BISON_CXX_WORKS): Add.
8653 * tests/local.at (AT_COMPILE_CXX): Use it.
8655 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8657 * data/glr.c (yylloc): Output this macro even if locations are not
8658 being generated, as the GLR parser needs it even in that case.
8659 Problem reported by Troy A. Johnson
8660 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
8662 * configure.ac (AC_INIT): Update to 1.875e.
8664 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
8666 * NEWS: Version 1.875d.
8667 * configure.ac (AC_INIT): Likewise.

8670 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
8671 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current

8673 supported by GCC 3.4.0.
8674 * README: Mention GNU m4 1.4 or later; mention m4 patches.
8675 * HACKING: Use ./bootstrap, not "make update" to import foreign files.

8691 character and string literals.
8692 (unexpected_end): New function.
8693 (unexpected_eof): Use it.

8716 gets copied to the output file.
8718 2004-04-28 Paul Eggert <eggert@twinsun.com>
8720 Get files from the gnulib and po repositories, instead of relying
8721 on them being in our CVS. Upgrade to latest versions of gnulib
8724 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
8725 * bootstrap: Bootstrap from gnulib and po repositories.
8726 Much of this code was stolen from GNU diff and GNU tar's bootstrap.

8755 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

8791 Remove, as these files are now generated automatically
8792 by bootstrap or automake.

8851 so that this include file can stand alone.
8852 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
8853 does this now. Include subpipe.h first after config.h, to
8854 test whether it can stand alone.
8856 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
8857 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
8860 * tests/synclines.at (%union synch line): Put a dummy member in
8861 the union, because empty unions aren't allowed in C. Caught
8864 2004-04-13 Jim Meyering <jim@meyering.net>
8866 * src/conflicts.c (conflicts_print): Correct format string typo:

8972 2004-02-02 Paul Eggert <eggert@twinsun.com>
8974 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
8975 $(top_srcdir)/lib and ../lib. This fixes a bug reported

8997 * src/output.c (output_skeleton): Rename local var.
8998 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
8999 Bison tokens, as this runs afoul of the 2003-10-07 change that
9000 disallowed NUL bytes in character constants or string literals.
9002 * tests/local.at: Require Autoconf 2.59's Autotest.
9003 * tests/testsuite.at: Don't include local.at, since we now assume
9004 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9006 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9007 multiple inclusion warnings.

9029 2003-10-05 Paul Eggert <eggert@twinsun.com>
9031 * NEWS: Don't document %no-default-prec, as it's still
9033 * doc/bison.texinfo: Document %no-default-prec only if
9034 the defaultprec flag is set. Normally it's not.
9036 2003-10-04 Paul Eggert <eggert@twinsun.com>
9038 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
9039 non-modifiable lvalue, instead of a modifiable one.
9040 * doc/bison.texinfo (Actions): Document that $$ can
9041 be assigned to. Do not claim that $$ and $N are
9042 array element references: user code should not rely on this.

9100 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
9102 2003-08-25 Akim Demaille <akim@epita.fr>
9104 When reducing initial empty rules, Bison parser read an initial
9105 location that is not defined. This results in garbage, and that
9106 affects Bison's own parser. Therefore we need (i) to extend Bison
9107 to support a means to initialize this location, and (ii) to use
9108 this CVS Bison to fix CVS Bison's parser.
9110 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9112 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9113 * src/parse-gram.y: Adjust.
9114 (%initial-action): New.
9115 (%error-verbose): Since we require CVS Bison, there is no reason
9117 * src/scan-gram.l: Adjust.
9118 * src/Makefile.am (YACC): New, to make sure we use our own parser.
9119 * data/yacc.c (yyparse): Use b4_initial_action.
9121 2003-08-25 Akim Demaille <akim@epita.fr>
9123 * doc/bison.texinfo: Don't promote stdout for error messages.
9125 2003-08-25 Akim Demaille <akim@epita.fr>
9127 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

9134 2003-08-25 Akim Demaille <akim@epita.fr>
9136 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
9139 2003-08-25 Akim Demaille <akim@epita.fr>
9141 * data/lalr1.cc (Parser::reduce_print_): New.
9144 2003-08-25 Akim Demaille <akim@epita.fr>
9146 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9147 error recovery loops. This patch is based on
9148 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9149 Also, augment the similarity between lalr1.cc and yacc.c.
9150 Note: the locations of error recovery rules are not correct yet.
9152 * data/lalr1.cc: Comment changes to augment the similarity between
9153 lalr1.cc and yacc.c.
9154 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9155 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9156 yyerrlab), when hitting EOF, pop the whole stack here instead of
9157 merely falling thru the default error handling mechanism.
9158 (yyerrorlab): New label, with the old contents of YYERROR,
9159 plus the following change: pop the stack of rhs corresponding
9160 to the production that invoked YYERROR. That is how Yacc
9161 behaves (required by POSIX).
9162 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9165 2003-08-25 Akim Demaille <akim@epita.fr>
9167 Tune local.at so that people can "autom4te -l autotest calc.at -o
9168 calc" for instance, to extract a sub test suite.
9170 * tests/testsuite.at: Move the initialization, Autotest version
9171 requirement, and AT_TESTED invocation into...
9172 * tests/local.at: here.
9173 * tests/testsuite.at: Include it for compatibility with Autoconf
9175 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9178 2003-08-04 Paul Eggert <eggert@twinsun.com>
9180 Rework code slightly to avoid gcc -Wtraditional warnings.
9181 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
9182 The returned value is now stored in *YY0. All callers changed.
9183 * src/output.c (merge_output): Adjust to the above change.
9185 2003-07-26 Paul Eggert <eggert@twinsun.com>
9187 * data/glr.c (YYASSERT): New macro.
9188 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
9189 yyresolveStates, yyprocessOneStack):
9190 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
9191 Derived from a suggestion by Frank Heckenbach.
9193 2003-07-25 Paul Eggert <eggert@twinsun.com>
9195 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
9196 for portability to K&R C (after ansi2knr, presumably). See
9197 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
9198 by Frank Heckenbach, though I have omitted the structure-initialization
9199 part of his glr-knr.diff patch since I recall that the Portable
9200 C Compiler didn't require that change.
9202 Let the user specify how to allocate and free memory.
9203 Derived from a suggestion by Frank Heckenbach in
9204 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
9205 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
9206 All uses of free, malloc, realloc changed to use these macros,
9207 and unnecessary casts removed.
9208 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
9210 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
9212 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
9213 use s.empty() rather than s == "" to test for empty string; see
9214 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
9217 2003-06-25 Akim Demaille <akim@epita.fr>
9219 * config/depcomp, config/install-sh: Update from masters.
9221 2003-06-20 Paul Eggert <eggert@twinsun.com>

9226 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9227 Remove unnecessary parentheses from uses.

9233 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
9234 yyreportTree): Do not assume that size_t is the same width as int,
9235 when printing sizes. Print sizes using an unsigned format.
9236 Problem reported by Frank Heckenbach in
9237 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
9239 Port to Forte Developer 7 C compiler.
9240 * data/glr.c (struct YYLTYPE): If locations are not being used,
9241 declare a single dummy member, as empty structs do not conform
9243 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
9244 the Forte Developer 7 C compiler complains that end-of-loop
9245 code is not reached.
9247 2003-06-17 Paul Eggert <eggert@twinsun.com>
9249 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to

9260 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
9261 Don't use 'index' in comments, as it's a builtin fn on some hosts.
9262 * lib/bitset_stats.c: Include gettext.h unconditionally, as
9263 per recent gettext manual's suggestion.
9264 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

9283 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
9284 * lib/vbitset.c, lib/vbitset.h: New files.
9285 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,

9289 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
9290 `How Can I Reset @code{yyparse}', since texinfo does not allow
9291 arbitrary @ in node names.
9293 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
9294 shouldn't be needed according to the gettext 0.12.1 documentation
9295 but which seem to be needed anyway: codeset.m4 glibc21.m4
9296 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

9318 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
9319 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
9320 the tests right now.
9321 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9322 yyerror are declared before use; C99 requires this.
9324 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9326 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
9328 (yyrecoverSyntaxError): Correct the logic for setting and testing
9330 Correct comment on handling EOF.
9331 Allow states with only a default reduction, rather than failing
9332 (I can't quite reconstruct why these were not allowed before).
9334 Fixes to avoid problem that $-N rules in GLR parsers can cause
9335 buffer overruns, corrupting state.
9337 * src/output.c (prepare_rules): Output max_left_semantic_context
9339 * src/reader.h (max_left_semantic_context): New variable declaration.
9340 * src/scan-gram.l (max_left_semantic_context): Define.

9346 Fixes to problems with location handling in GLR parsers reported by
9347 Frank Heckenbach (2003/06/05).
9349 * data/glr.c (YYLTYPE): Make trivial if locations not used.
9350 (YYRHSLOC): Add parentheses, and define only if locations used.

9354 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
9356 * tests/cxx-type.at: Exercise location information; update tests
9357 to differentiate output with and without locations.
9358 Remove forward declarations of yylex and yyerror---caused errors
9359 because default YYLTYPE not yet defined.
9360 Change semantic actions to compute strings, rather than printing
9361 them directly (to test proper passing of semantics values). Change
9362 output to prefix notation and update test data and expected results.
9363 (yylex): Track locations.
9364 (stmtMerge): Return value rather than printing, and include arguments
9367 2003-06-03 Paul Eggert <eggert@twinsun.com>
9369 Avoid warnings generated by GCC 2.95.4 when Bison is

9376 yy::Slice::operator[] (unsigned) const):
9377 Rename local vars to avoid warnings.
9378 * tests/glr-regression.at (Improper handling of embedded actions
9379 and $-N in GLR parsers): Remove unused local variable from yylex.
9380 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
9381 (void) as arg when not pure, since we now assume C89 when building
9382 Bison. Pacify GCC by using parameter.
9384 2003-06-02 Paul Eggert <eggert@twinsun.com>
9386 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
9387 yy::Location::lines, yy::Location::columns): Rename arguments
9388 to avoid shadowing; this removes a warning generated by GCC 3.3.
9390 2003-06-01 Paul Eggert <eggert@twinsun.com>
9392 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
9393 to g++, as GCC 3.3 complains if you do it.
9394 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
9395 everything that WARNING_CFLAGS has, except omit warnings
9396 not suitable for C++.
9397 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
9398 * tests/atlocal.in (CXXFLAGS): New var.
9399 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
9401 Fix a GLR parser bug I reported in February; see
9402 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
9403 The problem was that GLR parsers did not conform to the C standard,
9404 because actions like { $1 = $2 + $3; } expanded to expressions
9405 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9406 to a local variable. The C standard says that expressions
9407 like (var = f ()) + (var = f ()) have undefined behavior.
9408 Another problem was that GCC sometimes issues warnings that
9409 yyfill and its parameters are unused.
9411 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9413 (yyfill): New function.
9415 (yyuserAction): Change type of yynormal to bool, so that it matches
9416 the new yyfill signature. Mark it as possibly unused.
9419 Follow up on a bug I reported in February, where a Bison-generated
9420 parser can loop. Provide a test case and a fix for yacc.c. I
9421 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9422 The original bug report is in:
9423 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
9425 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9426 macro's size was becoming unwieldy.
9427 (yyerrlab): Do not discard an empty lookahead symbol, as this
9428 might destroy garbage.
9429 (yyerrorlab): New label, with the old contents of YYERROR,
9430 plus the following change: pop the stack of rhs corresponding
9431 to the production that invoked YYERROR. That is how Yacc
9432 behaves, and POSIX requires this behavior.
9433 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9434 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9435 Define 'alarm' to do nothing if unistd.h is not available.
9436 Add a new rule "exp: '-' error;" to test the above change to
9437 data/yacc.c. Use 'alarm' to abort any test taking longer than
9438 10 seconds, as it's probably looping.
9439 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9440 Also, the new yacc.c generates two fewer diagnostics for an
9443 2003-05-24 Paul Eggert <eggert@twinsun.com>
9445 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
9446 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
9447 This fixes a problem reported by John Bowman when the Compaq/HP
9448 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
9450 * data/yacc.c (union yyalloc): Likewise.
9451 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
9453 Switch from 'int' to 'bool' where that makes sense.

9536 parse-param arguments.
9537 (yy::b4_parser_class_name): Declare instance variables to
9538 hold parse-param arguments.
9539 * tests/calc.at: s/value/semantic_value/ because value clashes
9540 with a member of yy::b4_parser_class_name. Adjust C++ code
9541 to handle %parse-param. Enable %parse-param test in C++.
9543 2003-05-12 Paul Eggert <eggert@twinsun.com>
9545 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
9546 English a bit. Fix fclose typo. Change "const char" to "char
9547 const", and use ANSI C rather than K&R for "main". Suggest
9548 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
9549 and suggest yy_switch_to_buffer.
9551 2003-05-05 Paul Eggert <eggert@twinsun.com>
9553 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
9554 C89. This avoids a diagnostic on compilers that define __STDC__
9555 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
9556 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9558 2003-05-03 Paul Eggert <eggert@twinsun.com>
9560 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
9561 Do not overrun array bounds.
9562 This should fix a bug reported today by Olatunji Oluwabukunmi in
9563 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
9565 2003-04-29 Akim Demaille <akim@epita.fr>
9567 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
9568 * src/getargs.c, src/getargs.h: here, as bool, not int.
9569 (nondeterministic_parser): New.
9570 * src/parse-gram.y, src/scan-gram.l: Support
9571 %nondeterministic-parser.
9572 * src/output.c (prepare): Use nondeterministic_parser instead
9573 of glr_parser where appropriate.
9574 * src/tables.c (conflict_row, action_row, save_row)
9575 (token_actions, token_actions, pack_vector): Ditto.
9577 2003-04-29 Akim Demaille <akim@epita.fr>
9579 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
9581 2003-04-29 Akim Demaille <akim@epita.fr>
9583 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
9584 with %pure-parser and %locations to exercise the patch from Yakov
9587 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
9589 * data/yacc.c: (b4_lex_param): Corrected for the case where
9590 %lex-param is provided and %pure-parser isn't.
9592 2003-04-27 Paul Eggert <eggert@twinsun.com>
9594 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
9595 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
9596 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
9597 if it is not defined.
9598 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
9600 2003-04-26 Paul Eggert <eggert@twinsun.com>
9602 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
9603 Declare to be of type suitable for the ninf value itself, not of
9604 type suitable for the corresponding table, since the latter might
9605 be unsigned but the ninf value might be negative. This fixes a
9606 bug reported by Alexandre Duret-Lutz in
9607 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
9609 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
9610 invokes it. We shouldn't invoke it twice because it will attempt
9611 to put error.o in the archive twice. This fixes a glitch reported
9612 by Martin Mokrejs in
9613 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
9615 2003-04-21 Paul Eggert <eggert@twinsun.com>
9617 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
9620 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
9622 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
9623 Fix obvious typo that results in uncompilable GLR parsers
9624 when both %pure-parser and %locations are used. (trivial change)
9626 2003-04-17 Paul Eggert <eggert@twinsun.com>
9628 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
9629 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
9630 Do not insert the expected token via unput, as this runs afoul
9631 of a POSIX-compatibility bug in flex 2.5.31.
9632 All uses changed to BEGIN the parent state,
9633 since we no longer insert the expected token via unput.
9634 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
9635 that is no longer emitted after the above change.
9637 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
9638 the first one. This change is from Paul Hilfinger, and it fixes
9639 regression reported by Werner Lemberg in
9640 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
9642 (resolve_sr_conflict): Don't invoke state_errs_set
9643 unless one or more tokens have been explicitly made errors.
9644 Otherwise, the above change causes Bison to abort.
9646 * tests/existing.at (GNU pic Grammar): New test case, taken from
9649 2003-03-31 Akim Demaille <akim@epita.fr>
9651 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
9653 2003-03-31 Akim Demaille <akim@epita.fr>
9655 * src/output.c (prepare_symbols): Avoid trailing spaces in the
9658 2003-03-31 Akim Demaille <akim@epita.fr>
9660 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
9661 From Paul Hilfinger.
9663 2003-03-29 Akim Demaille <akim@epita.fr>
9665 * m4/error.m4: Do not put under dynamic conditions some code which
9666 expansion is under static control.
9668 2003-03-29 Akim Demaille <akim@epita.fr>
9670 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
9672 2003-03-29 Akim Demaille <akim@epita.fr>
9674 * doc/bison.texinfo (Strings are Destroyed): New.
9676 2003-03-13 Paul Eggert <eggert@twinsun.com>
9678 * .cvsignore: Add configure.lineno.
9679 * src/.cvsignore: Add yacc.
9680 * tests/.cvsignore: Add testsuite.log.
9681 * doc/fdl.texi: Sync with latest FSF version.
9683 2003-03-12 Paul Eggert <eggert@twinsun.com>
9685 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
9686 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
9687 cursor, instead of leaving it undefined. This fixes a bug
9688 reported by Tim Van Holder in
9689 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
9690 * tests/input.at (Torturing the Scanner): Test the scanner on
9691 an empty input file, which was Tim Van Holder's test case.
9693 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
9694 <sys/resource.h> can be included, include sys/time.h and
9695 sys/times.h first, if available. This works around the SunOS
9696 4.1.4 porting bug reported by Bruce Becker in
9697 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
9699 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
9700 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
9703 Merge changes from gnulib. This was prompted because the CVS
9704 snapshot didn't build on Solaris 7 due to strnlen problems.
9706 These changes need to be merged back into gnulib:
9707 * lib/hash.c: Include <stdbool.h> unconditionally.
9708 * m4/onceonly.m4 (m4_quote): New macro.
9709 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
9710 Quote AC_FOREACH variable-expansions properly.
9711 The 2003-01-03 obstack.h change also needs merging.
9712 {end of changes requiring merging}
9714 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
9715 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
9716 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
9717 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
9718 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
9719 New files, imported from gnulib.
9720 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
9723 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
9724 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
9727 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
9729 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
9730 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
9731 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
9732 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
9733 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
9734 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
9735 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
9736 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
9737 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
9738 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
9739 (jm_PREREQ_ARGMATCH): Remove.
9740 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
9741 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
9743 * src/system.h: Include <stdbool.h> unconditionally.
9745 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
9746 assuming at least C89 in the bitset code for some time now.
9748 2003-03-03 Akim Demaille <akim@epita.fr>
9752 2003-03-02 Akim Demaille <akim@epita.fr>
9754 * doc/bison.texinfo (Table of Symbols): Reactivate the
9755 documentation for %lex-param, and %parse-param.
9757 2003-03-02 Akim Demaille <akim@epita.fr>
9759 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
9760 generate verbose error messages.
9761 Use the number of tokens as an upper bound in yytname, as it
9762 cannot be a non terminal.
9764 2003-03-02 Akim Demaille <akim@epita.fr>
9766 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
9769 2003-03-02 Akim Demaille <akim@epita.fr>
9771 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
9772 Use them to exercise yycheck overrun.
9773 Based on Andrew Suffield's grammar.
9775 2003-03-02 Akim Demaille <akim@epita.fr>
9777 Create tests/local.at for Bison generic testing macros.
9779 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
9780 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
9782 * tests/calc.at (AT_CHECK_CALC): Adjust.
9783 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
9784 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
9785 * tests/local.at: here.
9786 (AT_COMPILE_CXX): Tags the tests using it as c++.
9787 Ignore the test if CXX is not functional.
9789 2003-03-01 Paul Eggert <eggert@twinsun.com>
9791 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
9792 not loc->end, since loc->end might contain garbage and this leads
9793 to undefined behavior on some platforms.
9794 (id_loc, token_start): Use (IF_LINTed) initial values that do not
9795 depend on *loc, so that the reader doesn't give the the false
9796 impression that *loc is initialized.
9797 (<INITIAL>"%%"): Do not bother setting code_start, since its value
9798 does not survive the return.
9800 2003-03-01 Akim Demaille <akim@epita.fr>
9802 * src/scan-gram.l (code_start): Always initialize it when entering
9803 into yylex, as SC_EPILOGUE is activated *before* the corresponding
9804 yylex invocation. An alternative would be making it static, but
9805 then it starts with the second %%'s beginning, instead of its end.
9807 2003-02-28 Paul Eggert <eggert@twinsun.com>
9809 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
9810 around a UnixWare 7.1.1 porting bug reported by John Hughes in
9811 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
9813 2003-02-26 Paul Eggert <eggert@twinsun.com>
9815 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
9816 Remove Sequent/Pyramid discussion (nobody uses them any more).
9817 Merge VMS and MS-DOS discussion; these ports may well be dead
9818 but let's keep mentioning them for now. Put <> around email
9819 addresses. Add copyright notice.
9821 2003-02-24 Paul Eggert <eggert@twinsun.com>
9823 * data/glr.c (yy_reduce_print): yylineno -> yylno,
9824 to avoid collision with flex use of yylineno.
9825 Problem reported by Bruce Lilly in
9826 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

9834 * data/lalr1.cc: Use temporary variables instead of casts to
9835 change integer types.
9836 Suggested by Paul Eggert.
9838 2003-02-21 Akim Demaille <akim@epita.fr>
9840 * doc/bison.texinfo: Use "location" consistently to refer to @n,
9841 to avoid confusions with lalr1.cc's notion of Position.
9842 Suggested by Paul Eggert.
9844 2003-02-20 Akim Demaille <akim@epita.fr>
9846 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
9847 before initial_columns.
9848 (location.hh): Use consistent variable names when defining the
9850 Use "last" so that we subtract from Positions, not from unsigned.
9852 2003-02-20 Akim Demaille <akim@epita.fr>
9854 * data/lalr1.cc (position.hh): New subfile, including the extended
9855 and Doxygen'ed documentation of class Position.
9856 (location.hh): Use it.
9857 Document a` la Doxygen.
9858 With the help of Benoit Perrot.
9860 2003-02-20 Akim Demaille <akim@epita.fr>
9862 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
9864 Redefine AT_YYERROR_SEES_LOC_IF using it.
9865 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
9867 Don't use the location in yy::Parser::error_ and
9868 yy::Parser::print_ when not %locations.
9869 Activate more lalr1.cc tests.
9871 2003-02-19 Akim Demaille <akim@epita.fr>
9873 * data/lalr1.cc: When displaying a line number, be sure to make it
9876 2003-02-19 Akim Demaille <akim@epita.fr>
9878 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
9880 (YYABORT, YYACCEPT, YYERROR): New.
9881 * tests/calc.at: Renable the lalr1.cc test.
9883 2003-02-19 Akim Demaille <akim@epita.fr>
9885 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
9886 error recovery, mixing with/without pops and discarding of the
9889 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
9891 2003-02-17 Paul Eggert <eggert@twinsun.com>
9893 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
9894 * tests/testsuite.at (AT_COMPILE): Use them.
9895 This fixes the testsuite problem reported by Robert Lentz in
9896 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
9898 2003-02-12 Paul Eggert <eggert@twinsun.com>
9900 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
9901 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
9902 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
9903 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
9904 Check for malloc failure, for consistency with yacc.c.
9905 (yytname_size): Remove, for consistency with yacc.c.
9907 The bug still remains in data/lalr1.cc, as I didn't have time
9910 2003-02-06 Akim Demaille <akim@epita.fr>
9912 * configure.ac (GXX): Rename as...
9913 (CXX): this, to keep the original Autoconf semantics.
9915 * data/lalr1.cc: Fix b4_copyright invocations.
9916 If YYDEBUG is not defined, don't depend upon name_ being defined.

9927 * tests/testsuite.at (AT_COMPILE_CXX): New.
9928 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
9929 locations in a more synthetic way.
9930 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
9932 Adjust the C locations to match those from Emacs: first column is
9934 Change all the expected results.
9935 Conform to the GCS: simplify the locations when applicable.
9936 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
9937 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
9938 these CPP macros with the m4 macros new defined by...

9943 (AT_CHECK_POPDEFS): Undefine them.
9944 (AT_CHECK_CALC_LALR1_CC): New.
9945 Use it for the first lalr1.cc test.
9947 2003-02-04 Akim Demaille <akim@epita.fr>
9949 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
9950 Location as is defined.
9952 2003-02-04 Akim Demaille <akim@epita.fr>
9954 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
9955 name_ being defined.

10006 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10007 param to have same name as that of enum, so that we don't use
10008 "s" to stand for a non-state.
10010 2003-02-02 Akim Demaille <akim@epita.fr>
10012 * src/scan-skel.l: Scan more than one inert character per yylex
10015 2003-02-01 Paul Eggert <eggert@twinsun.com>
10019 * po/LINGUAS: Add ms.
10021 2003-01-30 Akim Demaille <akim@epita.fr>
10023 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10025 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10027 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10030 Changes in response to error report by S. Eken: GLR mode does not
10031 handle negative $ indices or $ indices in embedded rules correctly.
10032 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10034 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10035 (b4_rhs_location): Ditto.
10036 (yyfill): New function to copy from stack tree into array
10038 (yyuserAction): Modify to allow incremental move of semantic values
10039 to rhs array when in GLR mode.
10040 Define YYFILL to use in user-defined actions to fill semantic array
10042 Remove dummy use of yystack, as there is now a guaranteed use.
10043 (yydoAction): Modify to allow incremental move of semantic values
10044 to rhs array when in GLR mode.
10045 (yyresolveAction): Ditto.
10046 (yyglrShiftDefer): Update comment.
10047 (yyresolveStates): Use X == NULL for pointers, not !X.
10048 (yyglrReduce): Ditto.
10049 (yydoAction): Ditto
10051 * tests/glr-regr1.at: Rename to ...
10052 * tests/glr-regression.at: Add new regression test for the problems
10053 described above (adapted from S. Eken).
10054 Update copyright notice.
10055 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10056 * tests/Makefile.am: Ditto.
10058 2003-01-28 Paul Eggert <eggert@twinsun.com>
10060 * data/lalr1.cc: Do not use @output_header_name@ unless
10061 b4_defines_flag is set. This fixes two bugs reported by
10063 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10064 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10066 2003-01-21 Paul Eggert <eggert@twinsun.com>
10068 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10069 we don't need to worry about yyerrlab1 being reported as an
10070 "unused label" by non-GCC C compilers. The downside is that if
10071 locations are used then a couple of statements are duplicated each
10072 time YYERROR is invoked, but the upside is that the warnings
10074 (yyerrlab1): Move code to YERROR.
10075 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10076 This reverts some of the 2002-12-27 change.
10078 2003-01-17 Paul Eggert <eggert@twinsun.com>
10080 * src/output.c (symbol_printers_output): Fix typo that led
10081 to core dump. Problem reported by Antonio Rus in
10082 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10084 2003-01-13 Akim Demaille <akim@epita.fr>,
10085 Quoc Peyrot <chojin@lrde.epita.fr>,
10086 Robert Anisko <anisko_r@lrde.epita.fr>
10088 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10089 when the stacks contain one element, as the loop would otherwise
10090 free the last state, and then use the top state (the one we just
10091 popped). This means that the initial elements will not be freed
10092 explicitly, as is the case in yacc.c; it is not a problem, as
10093 these elements have fake values.
10095 2003-01-11 Paul Eggert <eggert@twinsun.com>
10097 * NEWS: %expect-violations are now just warnings, reverting
10098 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10099 bootstrapping problem reported by Matthias Klose; see
10100 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10101 * src/conflicts.c (conflicts_print): Likewise.
10102 * tests/conflicts.at (%expect not enough, %expect too much,
10103 %expect with reduce conflicts): Likewise.
10104 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10105 that the warning is enabled if the number of conflicts changes
10106 (not necessarily increases).
10108 * src/getargs.c (version): Update copyright year.
10110 2003-01-09 Akim Demaille <akim@epita.fr>
10112 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10114 2003-01-08 Paul Eggert <eggert@twinsun.com>
10116 * Makefile.maint (WGETFLAGS):
10117 New macro, containing "-C off" to disable proxy caches.
10118 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10119 (rel-check): Use $(WGET) instead of wget.
10121 2003-01-06 Paul Eggert <eggert@twinsun.com>
10123 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10124 the GLR paper of Scott, Johnstone and Hussain.
10126 2003-01-04 Paul Eggert <eggert@twinsun.com>
10128 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10129 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10130 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10131 (EXTRA_LIBRARIES): New var, for liby.a.
10132 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10133 (EXTRA_SCRIPTS): New var, for yacc.
10135 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10136 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10137 Problem reported by Nelson H. F. Beebe.
10139 2003-01-03 Paul Eggert <eggert@twinsun.com>
10141 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10142 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10143 when compiling Bison 1.875's `bitset bset = obstack_alloc
10144 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10146 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10147 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10148 grow to a huge size with typical invocation.
10150 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10151 Use the pattern recommended by Autoconf 2.57, except also protect
10152 against double-definition.
10153 * src/system.h: Likewise.
10154 Portability issues reported by Nelson H. F. Beebe.
10156 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10157 All uses changed. Provide a definition in both C and C++.
10158 (yytrue, yyfalse): Define even if defined (__cplusplus).
10160 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10161 Reported by Nelson H. F. Beebe.
10163 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10165 2003-01-02 Paul Eggert <eggert@twinsun.com>
10167 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10168 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10169 Bug reported by Nelson H. F. Beebe.
10171 2003-01-01 Paul Eggert <eggert@twinsun.com>
10175 2002-12-30 Paul Eggert <eggert@twinsun.com>
10177 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10179 (<INITIAL>","): Here. This causes stray "," to be treated
10182 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
10183 last brace in braced code when not in Yacc mode, for compatibility
10184 with Bison 1.35. This resurrects the 2001-12-15 patch to
10187 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
10188 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
10190 2002-12-28 Paul Eggert <eggert@twinsun.com>
10192 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
10193 that of SYM's type. This fixes Debian bug 168069, reported by
10196 2002-12-28 Paul Eggert <eggert@twinsun.com>
10200 Switch back to the Yacc style of conflict reports, undoing some
10201 of the 2002-07-30 change.
10202 * doc/bison.texinfo (Understanding): Use Yacc style for
10203 conflict reports. Also, use new way of locating rules.
10204 * src/conflicts.c (conflict_report):
10205 Renamed from conflict_report_yacc, removing the old
10206 'conflict_report'. Translate the entire conflict report at once,
10207 so that we don't assume that "," has the same interpretation in
10209 (conflicts_output): Use Yacc-style conflict report for each state,
10210 instead of our more-complicated style.
10211 (conflicts_print): Use Yacc-style conflict report, except print
10212 the input file name when not emulating Yacc.
10213 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10214 Conflicted Reduction, %expect not enough, %expect too much,
10215 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
10216 * tests/existing.at (GNU Cim Grammar): Likewise.
10217 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
10219 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
10220 fatal): Don't invoke fflush; it's not needed and it might even be
10221 harmful for stdout, as stdout might not be open.
10222 * src/reduce.c (reduce_print): Likewise.
10224 2002-12-27 Paul Eggert <eggert@twinsun.com>
10226 Fix a bug where error locations were not being recorded correctly.
10227 This problem was originally reported by Paul Hilfinger in
10228 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
10230 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10231 top of the location stack's error locations.
10232 (yyerrlab): Set it. When discarding a token, push its location
10233 onto yylerrsp so that we don't lose track of the error's end.
10234 (yyerrlab1): Now is only the target of YYERROR, so that we can
10235 properly record the location of the action that failed. For GCC
10236 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10237 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10238 (yyerrlab2): New label, which yyerrlab now falls through to.
10239 Compute the error's location by applying YYLLOC_DEFAULT to
10240 the locations of all the symbols that went into the error.
10241 * doc/bison.texinfo (Location Default Action): Mention that
10242 YYLLOC_DEFAULT is also invoked for syntax errors.
10243 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10244 Error locations include the locations of all the tokens that were
10245 discarded, not just the last token.
10247 2002-12-26 Paul Eggert <eggert@twinsun.com>
10249 * src/files.c: Include quote.h.
10250 (compute_output_file_names): Warn if we detect conflicting
10251 outputs to the same file. This should catch the misunderstanding
10252 exemplified by Debian Bug 165349, reported by Bruce Stephens..
10254 * src/conflicts.c (conflicts_print): If the user specifies
10255 "%expect N", report an error if there are any reduce/reduce
10256 conflicts. This is what the manual says should happen.
10257 This fixes Debian bug 130890, reported by Anthony DeRobertis.
10258 * tests/conflicts.at (%expect with reduce conflicts): New test.
10260 Don't use m4_include on relative file names, as it doesn't work as
10261 desired if there happens to be a file with that name under ".".
10263 * m4sugar/version.m4: Remove; it was included but it wasn't used.
10264 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
10265 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
10266 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
10267 * src/output.c (output_skeleton): Use full path names when
10268 specifying a file to include; don't rely on include path, as
10269 it's unreliable when the working file contains a file with
10272 2002-12-25 Paul Eggert <eggert@twinsun.com>
10274 Remove obsolete references to bison.simple and bison.hairy.
10275 Problem mentioned by Aubin Mahe in
10276 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
10277 * data/glr.c: Comment fix.
10278 * doc/bison.1: Remove references. Also, mention "yacc".
10280 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
10283 * src/parse-gram.y (declaration): Use enum "report_states" rather
10284 than its numeric value 1.
10286 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
10287 opening a new one. This fixes Debian bug 165349, reported by
10290 2002-12-24 Paul Eggert <eggert@twinsun.com>
10294 * Makefile.maint (cvs-update): Don't assume that the shell
10295 supports $(...), as Solaris sh doesn't.
10297 * src/parse-gram.y (lloc_default): Remove test for empty
10298 nonterminals at the end, since it didn't change the result.
10300 2002-12-24 Paul Eggert <eggert@twinsun.com>
10302 If the user does not define YYSTYPE as a macro, Bison now declares it
10303 using typedef instead of defining it as a macro. POSIX requires this.
10304 For consistency, YYLTYPE is also declared instead of defined.
10306 %union directives can now have a tag before the `{', e.g., the
10307 directive `%union foo {...}' now generates the C code
10308 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10309 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10310 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10311 instead of `yyltype'.
10313 `yystype' and `yyltype' are now obsolescent macros instead of being
10314 typedefs or tags; they are no longer documented and will be
10315 withdrawn in a future release.
10317 * data/glr.c (b4_location_type): Remove.
10318 (YYSTYPE): Renamed from yystype.
10319 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10320 (struct YYLTYPE): Renamed from struct yyltype.
10321 (YYLTYPE): Renamed from yyltype.
10322 (yyltype, yystype): New (and obsolescent) macros,
10323 for backward compatibility.
10324 * data/yacc.c: Likewise.
10326 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10327 does not specify a union tag. This is for compatibility with
10330 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10331 const *, since it is now modified by stripping surrounding { }.
10332 (current_braced_code): Remove.
10333 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10334 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10335 trailing " {...}". Now of type <chars>.
10336 (grammar_declaration): Adjust to bundled tokens.
10337 (code_content): Remove; stripping is now done by add_param.
10338 (print_token_value): Print contents of bundled tokens.
10339 (token_name): New function.
10341 * src/reader.h (braced_code, current_braced_code): Remove.
10342 (token_name): New decl.
10344 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10345 token_type, not braced_code code_kind. All uses changed.
10346 (SC_PRE_CODE): New state, for scanning after a keyword that
10347 has (or usually has) an immediately-following braced code.
10348 (token_type): New local var, to keep track of which token type
10349 to return when scanning braced code.
10350 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
10351 <INITIAL>"%parse-param", <INITIAL>"%printer",
10352 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10353 instead of returning a token type immediately.
10354 (<INITIAL>"{"): Set token type.
10355 (<SC_BRACED_CODE>"}"): Use it.
10356 (handle_action_dollar, handle_action_at): Now returns bool
10357 indicating success. Fail if ! current_rule; this prevents a core dump.
10358 (handle_symbol_code_dollar, handle_symbol_code_at):
10359 Remove; merge body into caller.
10360 (handle_dollar, handle_at): Complain in invalid contexts.
10362 * NEWS, doc/bison.texinfo: Document the above.
10363 * NEWS: Fix years and program names in copyright notice.
10365 2002-12-17 Paul Eggert <eggert@twinsun.com>
10367 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
10368 Reporting, Table of Symbols): Omit mentions of %lex-param and
10369 %parse-param from the documentation for now.
10371 2002-12-15 Paul Eggert <eggert@twinsun.com>
10373 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10374 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10375 lookahead symbol, and which sets yychar in parser actions) and it
10376 disagreed with the Bison documentation. Bug
10377 reported by Andrew Walrond.
10379 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10380 as the caller now does that.
10381 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10382 (YYEMPTY): Parenthesize right hand side, since others use it.
10383 (yyparse): Don't assume that our generated code is the only code
10386 2002-12-13 Paul Eggert <eggert@twinsun.com>
10390 POSIX requires a "yacc" command.
10391 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
10392 (MOSTLYCLEANFILES): Add yacc.
10394 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
10395 as an alias for bison y.
10397 * po/LINGUAS: Add da.
10399 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
10400 problem with latest <getopt.h>.
10401 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
10403 * doc/fdl.texi: Upgrade to 1.2.
10404 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
10405 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
10406 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
10408 * config/install-sh: Sync with autotools.
10410 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
10411 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10412 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
10413 locations are requested.
10414 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
10415 locations are requested.
10417 2002-12-12 Paul Eggert <eggert@twinsun.com>
10419 Remove unportable casts and storage allocation tricks.
10420 While we're at it, remove almost all casts, since they
10421 usually aren't needed and are a sign of trouble.
10423 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10425 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10426 the pointer DSET returned by malloc; this isn't portable.
10427 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10428 Similarly for DERIVES.
10429 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10430 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10431 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10433 * src/derives.c (derives_compute): Do not bother invoking
10434 int_of_rule_number, since rule numbers are integers.
10436 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10437 rather than XMALLOC (char, N).
10439 * src/files.c (filename_split): Rewrite to avoid cast.
10441 * src/gram.h (symbol_number_as_item_number,
10442 item_number_as_symbol_number, rule_number_as_item_number,
10443 item_number_as_rule_number):
10444 Now inline functions rather than macros, to avoid casts.
10445 * src/state.h (state_number_as_int): Likewise.
10446 * src/tables.c (state_number_to_vector_number,
10447 symbol_number_to_vector_number): Likewise.
10449 * src/gram.h (int_of_rule_number): Remove; no longer used.
10451 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10452 since the resulting storage is always stored into.
10454 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10457 * src/muscle_tab.c (muscle_m4_output):
10458 Now inline. Return bool, not int.
10459 * src/state.c (state_compare): Likewise.
10460 * src/symtab.c (symbol_check_defined,
10461 symbol_check_alias_consistency, symbol_pack, symbol_translation,
10462 hash_compare_symbol, hash_symbol):
10464 * src/uniqstr.c (uniqstr_print): Likewise.

10472 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10473 * src/muscle_tab.c (muscles_m4_output):
10474 Use new functions instead of casting old functions unportably.

10477 symbols_token_translations_init):
10479 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10481 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10482 var instead of casting to long, to avoid casts.
10483 (prepare_states): Use MALLOC rather than alloca, so that we don't
10484 have to worry about alloca.
10485 * src/state.c (state_hash_lookup): Likewise.
10487 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10488 local var instead of casting to unsigned char, to avoid casts.

10491 STATE_ALLOC): Remove.
10492 (transitions_new, errs_new, reductions_new, state_new): Use malloc

10497 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10499 * src/symtab.c (symbol_free): Remove; unused.

10510 (<inttypes.>, <stdint.h>): Include if available.
10511 (uintptr_t): New type, if system lacks it.
10512 (CALLOC, MALLOC, REALLOC): New macros.
10513 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10516 * src/tables.c (table_size): Now int, to pacify GCC.

10529 2002-12-09 Paul Eggert <eggert@twinsun.com>
10531 Change identifier spellings to avoid collisions with names
10532 that are reserved by POSIX.
10534 Don't use names ending in _t, since POSIX reserves them.
10535 For consistency, remove _e and _s endings -- they're weren't
10536 needed to remove ambiguity. All uses changed.
10537 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10538 turn was just renamed from struniq_t.
10539 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10540 which in turn was just renamed from struniq_processor_t.
10541 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

10612 value_t_as_yystype -> value_as_yystype.
10614 Don't include <errno.h> in the mainstream code, since it
10615 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
10616 * lib/get-errno.c, lib/get-errno.h: New files.
10617 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

10632 likewise for "STRUNIQ" and "UNIQSTR".
10633 * src/uniqstr.c: Renamed from src/struniq.c.
10634 * src/uniqstr.h: Renamed from src/struniq.h.
10635 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

10645 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.

10658 (ACTION_MAX): Remove; unused.
10659 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
10660 Unnecessary casts removed from above defines.
10663 Fix misspelling in names.
10664 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
10665 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
10669 * lib/timevar.c (timevar_report): Renamed from time_report,
10670 for consistency with other names.
10671 * lib/timevar.h (timevar_report): New decl.
10672 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
10675 Sort include-file uses.
10677 Reorder all include files under src to be in the order "system.h".
10678 then the ../lib include files in angle brackets (alphabetized),
10679 then the . include files in double-quotes (alphabetized). Fix
10680 dependency breakages encountered in this process, as follows:
10681 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
10682 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
10683 * src/state.h: Include "symtab.h".
10685 2002-12-08 Paul Eggert <eggert@twinsun.com>
10687 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
10688 since this causes problems when __file__ contains character
10689 sequences like "@" that are treated specially by src/scan-skel.l.
10690 Instead, just use the file's basename. This fixes the bug
10691 reported by Martin Mokrejs in
10692 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
10694 2002-12-06 Paul Eggert <eggert@twinsun.com>
10696 Add support for rules that do not have trailing semicolons, as
10697 POSIX requires. Improve the quality of locations in Bison
10700 * src/location.c: Include <quotearg.h>.
10701 (empty_location): Now const.
10702 (location_print): New function. Follow the recommendation of the
10703 GNU Coding Standards for locations that span file boundaries.
10704 * src/location.h: Do not include <quotearg.h>; no longer needed.
10705 (boundary): New type.
10706 (location_t): Use it. This allows locations to span file boundaries.
10707 All member uses changed: file -> start.file or end.file (as needed),
10708 first_line -> start.line, first_column -> start.column,
10709 last_line -> end.line, last_column -> end.column.
10710 (equal_boundaries): New function.
10711 (LOCATION_RESET, LOCATION_STEP): Remove.
10712 (LOCATION_PRINT): Remove. All callers changed to use location_print.
10713 (empty_location): Now const.
10714 (location_print): New decl.
10715 * src/parse-gram.y (lloc_default): New function, which handles
10716 empty locations more accurately.
10717 (YYLLOC_DEFAULT): Use it.
10718 (%token COLON): Remove.
10719 (%token ID_COLON): New token.
10721 (declarations, rules): Remove trailing semicolon.
10722 (declaration, rules_or_grammar_declaration):
10723 Allow empty (";") declaration.
10724 (symbol_def): Remove empty actions; no longer needed.
10725 (rules_or_grammar_declaration): Remove trailing semicolon.
10726 (semi_colon.opt): Remove.
10727 * src/reader.h: Include location.h.
10728 (scanner_cursor): New decl.
10729 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
10731 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
10733 (STEP): Remove. No longer needed, now that adjust_location does
10734 the work. All uses removed.
10735 (scanner_cursor): New var.
10736 (adjust_location): Renamed from extend_location. It now sets
10737 *loc and adjusts the scanner cursor. All uses changed.
10738 Don't bother testing for CR.
10739 (handle_syncline): Remove location arg; now updates scanner cursor.
10740 All callers changed.
10741 (unexpected_end_of_file): Now accepts start boundary of token or
10742 comment, not location. All callers changed. Update scanner cursor,
10744 (SC_AFTER_IDENTIFIER): New state.
10745 (context_state): Renamed from c_context. All uses changed.
10746 (id_loc, code_start, token_start): New local vars.
10747 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
10748 processing of Yacc white space and equivalents here.
10749 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10750 instead of returning ID immediately, since we need to search for
10751 a subsequent colon.
10752 (<INITIAL>"'", "\""): Save token_start.
10753 (<INITIAL>"%{", "{", "%%"): Save code_start.
10754 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
10755 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
10756 BEGIN context_state at end, not INITIAL.
10757 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
10758 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
10759 Return correct token start.
10760 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
10761 the start of a character, string or multiline comment is found.
10762 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
10763 Reduction): Adjust reported locations to match the more-precise
10764 results now expected.
10765 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
10766 * tests/reduce.at (Useless Rules, Reduced Automaton,
10767 Underivable Rules): Likewise.
10768 * tests/regression.at (Invalid inputs): No longer `expecting ";"
10769 or "|"' now that so many other tokens are allowed by the new grammar.
10771 * src/complain.h (current_file): Remove duplicate decl;
10772 current_file is now owned by files.h.
10773 * src/complain.c, src/scan-gram.l: Include files.h.
10775 2002-12-06 Paul Eggert <eggert@twinsun.com>
10777 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
10778 promotes to int; it might be unsigned int.
10779 * data/yacc.c (yy_reduce_print): Likewise.
10781 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
10782 be #defined in the prologue, not in the Bison declarations.
10783 This fixes Debian Bug 102878, reported by Shaul Karl.
10785 2002-12-02 Paul Eggert <eggert@twinsun.com>
10787 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
10788 * lib/strtoul.c: New file, from gnulib.
10789 This fixes a porting bug reported by Peter Klein in
10790 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
10792 2002-11-30 Paul Eggert <eggert@twinsun.com>
10794 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
10795 and put only a forward declaration in the prologue. This is for
10796 consistency with the other scanner helper functions.
10798 Type clashes now generate warnings, not errors, since it
10799 appears that POSIX may allow some grammars with type clashes.
10800 * src/reader.c (grammar_current_rule_check): Warn about
10801 type clashes instead of complaining.
10802 * tests/input.at (Type Clashes): Expect warnings, not complaints.
10804 Add Yacc library, since POSIX requires it.
10805 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
10806 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
10807 * lib/main.c, lib/yyerror.c: New files.
10809 gram_error can be static; it need not be extern.
10810 * src/reader.h (gram_error): Remove decl.
10811 * src/parse-gram.y (gram_error): Now static. Add static decl.
10812 (print_token_value): Omit parameter names from forward decl,
10815 2002-11-29 Paul Eggert <eggert@twinsun.com>
10817 * doc/bison.texinfo: Emphasize that yylex and yyerror must
10818 be declared before being used. E.g., one should typically
10819 declare them in the prologue. Use GNU coding style in examples.
10820 Put "const" consistently after the type it modifies. Mention
10821 that C99 supports "inline". Mention that yyerror traditionally
10824 %parse-param and %lex-param now take just one argument, the
10825 declaration; the argument name is deduced from the declaration.
10827 * doc/bison.texinfo (Parser Function, Pure Calling, Error
10828 Reporting, Table of Symbols): Document this.
10829 * src/parse-gram.y (add_param): New function.
10831 (declaration): Implement new rule for %parse-param and %lex-param.
10832 * src/scan-gram.l: "," now elicits a warning, rather than being
10833 a token; this is more compatible with byacc.
10834 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
10836 2002-11-27 Paul Eggert <eggert@twinsun.com>
10838 Rename identifiers to avoid real and potential collisions.
10840 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
10841 to avoid collision with lex macro described by Bruce Lilly in
10842 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
10843 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10844 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
10845 * src/parse-gram.y (print_token_value): Renamed from yyprint.
10847 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
10848 The name "yycontrol" violates the name space rules, and this stuff
10849 wasn't being used anyway.
10850 (input): Remove action; this stuff wasn't being used.
10851 (gram_error): Rename local variable yylloc -> loc.
10852 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
10853 (YY_DECL): Don't use "yy" at start of local variables.
10854 All uses changed, e.g., yylloc -> loc.
10855 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
10856 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
10857 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
10858 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
10860 * src/parse-gram.y (gram_error): loc is now const *.
10861 * src/reader.h (gram_error): Likewise.
10863 2002-11-24 Paul Eggert <eggert@twinsun.com>
10867 * tests/actions.at (Actions after errors): Use an output format
10868 more similar to that of the Printers and Destructors test.
10869 Test the position of the ';' token too.
10870 (Printers and Destructors): Likewise.
10871 (Printers and Destructors: %glr-parser): Remove for now, to avoid
10872 unnecessarily alarming people when the test fails.
10874 * data/yacc.c (yyerrlab1): Move this label down, so that the
10875 parser does not discard the lookahead token if the user code
10876 invokes YYERROR. This change is required for POSIX conformance.
10878 * lib/error.c: Sync with gnulib.
10880 2002-11-22 Paul Eggert <eggert@twinsun.com>
10882 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
10883 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
10884 * lib/xmalloc.c: Likewise.
10886 2002-11-20 Paul Eggert <eggert@twinsun.com>
10888 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
10890 2002-11-20 Paul Eggert <eggert@twinsun.com>
10892 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
10893 should use `if (! x) abort ();' rather than `assert (x);', and
10894 anyway it's one less thing to worry about configuring.
10896 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
10897 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
10898 and replace all instances of assert with abort.
10899 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
10900 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
10902 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
10903 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
10904 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
10905 hash_find_entry, hash_rehash, hash_insert): Likewise.
10906 * src/conflicts.c (resolve_sr_conflict): Likewise.

10912 state_reduction_find): Likewise.
10913 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
10914 symbol_pack): Likewise.
10915 * src/tables.c (conflict_row, pack_vector): Likewise.
10916 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10917 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10918 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,

10927 rather than assert.
10928 * src/tables.c (tables_generate): Likewise.
10930 * src/struniq.c (struniq_assert): Now returns void, and aborts
10931 if the assertion is false.
10932 (struniq_assert_p): Remove.
10933 * src/struniq.h: Likewise.
10935 2002-11-18 Paul Eggert <eggert@twinsun.com>
10937 * data/glr.c (yygetLRActions): Replace `yyindex' with
10938 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
10939 This fixes the regression with Sun ONE Studio 7 cc that I reported in
10940 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
10942 2002-11-18 Akim Demaille <akim@epita.fr>
10944 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
10946 From Tim Van Holder.
10948 2002-11-17 Paul Eggert <eggert@twinsun.com>
10950 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
10951 to "SyntaxError" for consistency with my 2002-11-15 change.
10953 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
10954 not define to {}, since this breaks the common use of `YYDPRINTF
10955 ((...));' if a single statement is desired (e.g. before `else').
10956 Work around GCC warnings by surrounding corresponding calls with
10958 (yyhasResolvedValue): Remove unused function.
10959 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
10961 (yyreportSyntaxError): Renamed from yyreportParseError.
10962 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
10964 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
10965 extern when possible. Remove unused initializations.
10967 2002-11-16 Akim Demaille <akim@epita.fr>
10969 Augment the similarity between GLR and LALR traces.
10971 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
10972 (YY_REDUCE_PRINT): New.
10973 (yyparse): Use them.
10974 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
10976 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
10977 state reached after the reduction/recovery, since...
10978 (yyparse, yyprocessOneStack): Report the state we are entering in.
10980 2002-11-16 Akim Demaille <akim@epita.fr>
10982 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
10983 Add support for --trace=skeleton.
10984 * src/scan-skel.l: %option debug.
10985 Scan strings of non-@ or \n instead of character by character.
10986 (scan_skel): Handle trace_skeleton.
10988 (@output_parser_name@, @output_header_name@): ``Restore'' their
10989 support (used to be M4 macros).
10990 * data/yacc.c: Quote larger chunks, a la glr.c.
10991 * data/lalr1.cc: Likewise.
10992 The header guards are no longer available, so use some other
10993 string than `YYLSP_NEEDED'.
10995 2002-11-16 Akim Demaille <akim@epita.fr>
10997 Make the ``Printers and Destructors'' test more verbose, taking
10998 `yacc.c''s behavior as (possibly wrong) reference.
11000 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11001 instead of fprint on stdout.
11002 Set and report the last_line of the symbols.
11003 Consistently display values and locations.
11005 2002-11-16 Paul Eggert <eggert@twinsun.com>
11007 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11009 2002-11-15 Paul Eggert <eggert@twinsun.com>
11011 * tests/actions.at (Actions after errors): New test case.
11013 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11014 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11015 tests/action.at, tests/calc.at, tests/conflicts.at,
11016 tests/cxx-type.at, tests/regression.at:
11017 "parse error" -> "syntax error" for POSIX compatibility.
11018 "parsing stack overflow..." -> "parser stack overflow" so
11019 that code matches Bison documentation.
11021 2002-11-15 Akim Demaille <akim@epita.fr>
11023 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11024 take two BRACED_CODE, not two string_content.
11025 Free the scanner's obstack when we are done.
11026 (code_content): New.
11027 * tests/calc.at: Adjust.
11028 * doc/bison.texinfo: Adjust.
11029 Also, make sure to include the `,' for these declarations.
11031 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11033 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11034 definition; avoids potential autoreconf problems.
11036 2002-11-15 Akim Demaille <akim@epita.fr>
11038 Always check the value returned by yyparse.
11040 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11041 returned by yyparse.
11042 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11044 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11045 returned by yyparse.
11047 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11049 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11052 2002-11-14 Paul Eggert <eggert@twinsun.com>
11054 * src/output.c (output_skeleton): Call xfopen instead of
11055 duplicating xfopen's body.
11057 Fix bugs reported by Nelson H. F. Beebe in
11058 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11060 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11061 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11062 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11063 file twice in the grammar, as an extra check.
11065 * tests/input.at (Torturing the Scanner): Surround the
11066 backslash-newline tests with "#if 0", to make it less likely that
11067 we'll run into compiler bugs. Bring back solitary \ inside
11068 comment, but add a closing comment to work around HP C bug. Don't
11069 test backslash-newline in C character constant.
11071 2002-11-14 Akim Demaille <akim@epita.fr>
11073 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11074 status of the compiler.
11075 Calling `exit 1' is no longer needed.
11076 Reported by Nelson H. F. Beebe.
11078 2002-11-14 Akim Demaille <akim@epita.fr>
11080 * tests/atlocal.in (CPPFLAGS): We have config.h.
11081 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
11083 * tests/actions.at, tests/calc.at, tests/conflicts.at,
11084 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11085 * tests/regression.at, tests/torture.at: Use them for all the
11086 grammars that are to be compiled.
11087 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11088 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11089 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11091 2002-11-14 Akim Demaille <akim@epita.fr>
11093 * doc/bison.texinfo: Various formatting changes (alignments in
11094 samples, additional @group/@end group, GCS in samples.
11095 Use @deffn instead of simple @table to define the directives,
11096 macros, variables etc.
11098 2002-11-13 Paul Eggert <eggert@twinsun.com>
11100 Fix some bugs reported by Albert Chin-A-Young in
11101 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11103 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11104 -o c"; the HP C compiler chatters during compilation.
11105 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11106 * tests/headers.at (export YYLTYPE): Likewise.
11108 * tests/input.at (Torturing the Scanner): Remove lines containing
11109 solitary backslashes, as they tickle a bug in the HP C compiler.
11111 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11112 comments, since they're not portable. Use GNU coding style.
11114 2002-11-13 Akim Demaille <akim@epita.fr>
11116 * data/yacc.c: Leave bigger chunks of quoted text.
11117 (YYDSYMPRINTF): New.
11118 Use it to report symbol activities.
11119 * data/glr.c (YYDSYMPRINTF): New.

11126 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11127 (yyglrReduce): Return yyok, not 0.
11128 This should avoid the enumerated-type warnings reported
11129 by Nelson H. F. Beebe in
11130 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11132 * lib/bbitset.h (BITSET_INLINE): Remove.
11133 * lib/bitset.h [! BITSET_INLINE]: Remove.
11134 (bitset_set, bitset_reset, bitset_test): Rename local vars
11135 to avoid shadowing warnings by GCC.
11137 * data/glr.c (inline): Remove #define. It's the user's
11138 responsibility to #define it away, just like 'const'.
11139 This fixes one of the bugs reported by Nelson H. F. Beebe in
11140 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11142 * Makefile.maint (po-check): Scan .l and .y files instead of the
11143 .c and the .h files that they generate. This fixes the bug
11144 reported by Tim Van Holder in:
11145 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11146 Look for N_ as well as for _. Try to avoid matching #define for
11148 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11149 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11150 * src/scan-gram.l: Revamp regular expressions so that " and '
11151 do not confuse xgettext.
11153 * src/struniq.h (struniq_new): Do not declare the return type
11154 to be 'const'; this violates the C standard.
11155 * src/struniq.c (struniq_new): Likewise.
11157 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11159 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11160 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11163 2002-11-12 Akim Demaille <akim@epita.fr>
11165 * Makefile.maint: Sync with Autoconf:
11166 (local_updates): New.
11168 2002-11-12 Akim Demaille <akim@epita.fr>

11182 2002-11-12 Akim Demaille <akim@epita.fr>
11184 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
11185 Use it to test the GLR parser.
11187 2002-11-12 Akim Demaille <akim@epita.fr>
11189 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
11191 * data/glr.c (yystos): New.
11192 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
11193 (YYDSYMPRINT): New.
11194 (yyval): Don't define it, it is handled via M4.
11195 (yyrecoverParseError): Free verbosely the discarded symbols.
11196 * data/yacc.c (yysymprint): Remove, rather...
11197 (b4_yysymprint_generate): invoke.
11198 * data/c.m4 (b4_yysymprint_generate): New.
11199 Accept pointers as arguments, as opposed to the version from
11201 (b4_yydestruct_generate): Likewise.
11202 * tests/cations.at (Printers and Destructors): Use Bison directives
11203 instead of CPP macros.
11204 Don't rely on internal details.
11206 2002-11-12 Akim Demaille <akim@epita.fr>
11208 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
11209 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
11210 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
11211 it against YYEMPTY and so forth), work on yytoken (i.e., set
11212 it to YYEMPTY etc.).
11213 (yydestruct): Replace with a b4_yydestruct_generate invocation.
11214 (b4_symbol_actions): Remove.
11215 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
11216 for 0, end-of-input.
11218 2002-11-12 Akim Demaille <akim@epita.fr>
11220 * doc/bison.texinfo (Destructor Decl): New.
11222 2002-11-12 Akim Demaille <akim@epita.fr>
11224 * src/tables.c (tables_generate): Use free for pointers that
11225 cannot be NULL, not XFREE.
11226 (pack_vector): Use assert, not fatal, for bound violations.
11227 * src/state.c (state_new): Likewise.
11228 * src/reader.c (reader): Likewise.
11229 * src/lalr.c (set_goto_map): Likewise.
11230 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
11233 2002-11-12 Akim Demaille <akim@epita.fr>
11235 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
11237 * src/scan-gram.l (last_string): Is global to the file, not to

11240 (epilogue.opt): do it here, and free the scanner's obstack.
11241 * src/reader.c (epilogue_set): Rename as...
11242 (epilogue_augment): this.
11243 * data/c.m4 (b4_epilogue): Defaults to empty.

11301 2002-11-11 Paul Eggert <eggert@twinsun.com>
11303 Revamp to fix many (but not all) of the C- and M4-related quoting
11304 problems. Among other things, this fixes the Bison bug reported
11305 by Jan Hubicka when processing the Bash grammar; see:
11306 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
11308 Use new @ escapes consistently. Represent brackets with @{ and @}
11309 rather than @<:@ and @:>@, since this works a bit better with dumb
11310 editors like vi. Represent @ with @@, since @ is now consistently
11311 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11312 __ofile__, to avoid unexpected expansions. Similarly, use @output
11313 rather than #output.
11315 * data/c.m4 (b4_copyright): Omit file name from comment, since
11316 the file name could contain "*/".
11317 (b4_synclines_flag): Don't quote the 2nd argument; it should already
11318 be quoted. All uses changed.
11320 * data/glr.c: Use new @ escapes consistently.
11321 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
11322 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
11323 Remove, since they couldn't handle arbitrary characters in file
11325 * data/lalr1.cc: Likewise.
11326 * data/yacc.c: Likewise.
11328 * src/files.c (output_infix): Remove; all uses removed.
11329 * src/files.h: Likewise.
11331 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
11332 mishandled funny characters in file names, and anyway it isn't
11334 * data/yacc.c: Likewise.
11335 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
11337 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
11338 * data/yacc.c: Likewise.
11340 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
11342 (muscle_init): Quote filename as a C string.
11343 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
11344 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
11345 * src/output.c (escaped_file_name_output): New function.
11346 (prepare_symbols): Quote tokens for M4.
11347 (prepare): Don't insert output_infix, output_prefix,
11348 output_parser_name, output_header_name; this is now down by scan-skel.
11349 Insert skeleton as a C string.
11351 * src/output.c (user_actions_output, symbol_destructors_output,
11352 symbol_printers_output): Quote filenames for C and M4.
11353 * src/reader.c (prologue_augment, epilogue_set): Likewise.
11355 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
11356 escapes other than \\ and \'; this simplifies the code.
11357 (<SC_STRING>): Likewise, for \\ and \".
11358 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
11359 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11360 Use new escapes @{ and @} for [ and ].
11362 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11363 them with auto vars.
11364 Switch to new escape scheme, where @ is the escape character uniformly.
11365 Abort if a stray escape character is found. Avoid unbounded input
11366 buffer when parsing non-escaped text.
11368 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
11369 __oline__, #output, $@, and @{ do not have unintended meanings.
11371 2002-11-09 Paul Eggert <eggert@twinsun.com>
11373 Fix the test failure due to GCC warnings described in
11374 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
11375 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
11376 evaluate to 0 if it's impossible for NINF to be in the respective
11378 (yygetLRActions, yyrecoverParseError): Use them.
11380 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11381 counted in the token inserted at end of file. Now takes
11382 location_t *, not location_t, so that the location can be
11383 adjusted. All uses changed.
11385 * tests/regression.at (Invalid inputs): Adjust wording in
11386 diagnostic to match the new behavior.
11388 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
11389 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11390 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11391 abort ();'. This reduces the runtime of the "Many lookaheads"
11392 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
11395 2002-11-07 Paul Eggert <eggert@twinsun.com>
11397 * src/parse-gram.y (CHARACTER): Remove unused token.
11400 * src/scan-gram.l: Remove stack option. We no longer use the
11401 stack, since the stack was never deeper than 1; instead, use the
11402 new auto var c_context to record the stacked value.
11404 Remove nounput option. At an unexpected end of file, we now unput
11405 the minimal input necessary to end cleanly; this simplifies the
11408 Avoid unbounded token sizes where this is easy.
11410 (unexpected_end_of_file): New function.
11411 Use it to systematize the error message on unexpected EOF.
11412 (last-string): Now auto, not static.
11413 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
11414 (scanner_last_string_free): Remove; not used.
11415 (percent_percent_count): Move decl to just before use.
11416 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
11417 not the (never otherwised-used) CHARACTER.
11419 2002-11-07 Akim Demaille <akim@epita.fr>
11421 Let yyerror always receive the msg as last argument, so that
11422 yyerror can be variadic.
11424 * data/yacc.c (b4_yyerror_args): New.
11425 Use it when calling yyerror.
11426 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

11432 2002-11-06 Akim Demaille <akim@epita.fr>
11434 #line should have quoted strings.
11435 Ideally, this should be done by m4_quotearg.

11439 * src/output.c (symbol_printers_output)
11440 (symbol_destructors_output): Quote the file name.

11456 (prepare): Define 'b4_synclines_flag'.
11457 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
11459 2002-11-06 Akim Demaille <akim@epita.fr>
11461 * src/main.c (main): Free `infile'.

11464 * src/output.c (user_actions_output, symbol_destructors_output)
11465 (symbol_printers_output): Use the location's file name, not

11469 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11471 * src/tables.c (matching_state): Don't allow states to match if
11472 either has GLR conflict entries.
11474 2002-11-05 Paul Eggert <eggert@twinsun.com>
11476 * src/scan-gram.l: Use more accurate diagnostics, e.g.
11477 "integer out of range" rather than "invalid value".
11478 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
11481 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
11482 Also, remove one static variable in the scanner.
11484 * src/scan-gram.l (braces_level): Now auto, not static.
11485 Initialize to zero if the compiler is being picky.
11486 (INITIAL): Clear braces_level instead of incrementing it.
11487 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
11488 as POSIX 1003.1-2001 requires.
11489 * src/system.h (IF_LINT): New macro, taken from coreutils.
11490 * configure.ac: Define "lint" if --enable-gcc-warnings.
11492 2002-11-05 Akim Demaille <akim@epita.fr>
11494 * src/scan-gram.l: When it starts with `%', complain about the
11495 whole directive, not just that `invalid character: %'.
11497 2002-11-04 Akim Demaille <akim@epita.fr>
11499 * Makefile.maint: Update from Autoconf.
11500 (update, cvs-update, po-update, do-po-update): New.
11502 2002-11-04 Akim Demaille <akim@epita.fr>
11504 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
11506 Have yyerror `use' its arguments.
11507 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
11508 returns true when location & yacc & pure & parse-param.
11509 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
11511 2002-11-04 Akim Demaille <akim@epita.fr>
11513 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
11515 * src/scan-gram.l: Use [\'] instead of ['] to pacify
11518 Use quote, not quote_n since LOCATION_PRINT no longer uses the
11521 2002-11-03 Paul Eggert <eggert@twinsun.com>
11523 * src/reader.c (get_merge_function, grammar_current_rule_check):
11524 Use consistent diagnostics for reporting type name clashes.
11525 Quote the types with <>, for consistency with Yacc.
11526 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
11528 2002-11-03 Akim Demaille <akim@epita.fr>
11530 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
11532 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
11533 (b4_parse_param): Remove.
11534 Use b4_identification.
11535 Propagate b4_pure_args where needed to pass them to yyerror.
11536 * data/glr.m4 (b4_parse_param): Remove.
11537 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

11540 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
11541 b4_user_formals and b4_user_args.
11542 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
11543 (yyreportAmbiguity): When using a pure parser, also need
11544 the location, and the parse-params.
11546 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
11547 When using a pure parser, also need the parse-params.
11549 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
11550 (%pure-parser + %parse-param) LALR and GLR parsers.
11551 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
11552 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
11553 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
11554 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

11556 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
11557 * doc/bison.texinfo: Untabify the whole file.
11558 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
11559 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
11560 (Error Reporting): Adjust to these new directives.
11561 Document %error-verbose, deprecate YYERROR_VERBOSE.
11563 2002-11-03 Akim Demaille <akim@epita.fr>
11565 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
11566 AT_CHECK_CALC_GLR invocations to use % directives, instead of
11567 command line options.
11568 * tests/cxx-type.at: Formatting changes.
11570 2002-11-03 Paul Eggert <eggert@twinsun.com>
11572 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
11573 to count columns correctly, and to check for invalid inputs.
11575 Use mbsnwidth to count columns correctly. Account for tabs, too.
11576 Include mbswidth.h.
11577 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
11578 (extend_location): New function.
11579 (YY_LINES): Remove.
11581 Handle CRLF in C code rather than in Lex code.
11582 (YY_INPUT): New macro.
11583 (no_cr_read): New function.
11585 Scan UCNs, even though we don't fully handle them yet.

11588 Handle backslash-newline correctly in C code.
11589 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
11590 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
11592 (tag, splice): New EREs. Do not allow NUL or newline in tags.
11593 Use {splice} wherever C allows backslash-newline.
11594 YY_STEP after space, newline, vertical-tab.
11595 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
11597 (letter, id): Don't assume ASCII; e.g., spell out a-z.
11599 ({int}, handle_action_dollar, handle_action_at): Check for integer
11602 (YY_STEP): Omit trailing semicolon, so that it's more like C.
11604 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
11605 as well as \000. Check for UCHAR_MAX, not 255.
11606 Allow \x with an arbitrary positive number of digits, as in C.
11607 Check for overflow here.
11608 Allow \? and UCNs, for compatibility with C.
11610 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
11611 with quote slot used by complain_at.
11613 * tests/input.at: Add tests for backslash-newline, m4 quotes
11614 in symbols, long literals, and funny escapes in strings.
11616 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
11617 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
11618 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
11619 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
11620 * m4/mbswidth.m4: New file, from GNU coreutils.
11622 * doc/bison.texinfo (Grammar Outline): Document // comments.
11623 (Symbols): Document that trigraphs have no special meaning in Bison,
11624 nor is backslash-newline allowed.
11625 (Actions): Document that trigraphs have no special meaning.

11630 2002-11-02 Paul Eggert <eggert@twinsun.com>
11632 * src/reader.c: Don't include quote.h; not needed.
11633 (get_merge_function): Reword warning to be consistent with
11634 type clash diagnostic in grammar_current_rule_check.
11636 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
11637 bug in trigraph handling.
11639 * src/output.c (prepare_symbols): When printing token names,
11640 escape "[" as "@<:@" and likewise for "]".
11642 * src/system.h (errno): Remove declaration, as we are now
11643 assuming C89 or better, and C89 guarantees errno.
11645 2002-10-30 Paul Eggert <eggert@twinsun.com>
11647 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
11648 Check for close failures.
11649 * src/files.h (xfclose): Return void, not int, since it always
11651 * src/files.c (xfclose): Likewise. Report I/O error if ferror
11653 * src/output.c (output_skeleton): Use xfclose rather than fclose
11654 and ferror. xfclose now checks ferror.
11656 * data/glr.c (YYLEFTMOST_STATE): Remove.
11657 (yyreportTree): Use a stack-based leftmost state. This avoids
11658 our continuing battles with bogus warnings about initializers.
11660 2002-10-30 Akim Demaille <akim@epita.fr>
11662 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
11665 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11667 * tests/glr-regr1.at: New test for reported regressions.
11668 * tests/testsuite.at: Add glr-regr1.at test.
11669 * tests/Makefile.am: Add glr-regr1.at test.

11675 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
11676 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
11677 we use malloc. Don't assume 'A' through 'Z' are contiguous.
11678 Don't assume strdup exists; POSIX says its an XSI extension.
11679 Check for buffer overflow on input.
11681 2002-10-24 Akim Demaille <akim@epita.fr>
11683 * src/output.c (output_skeleton): Don't disable M4sugar comments
11684 too soon: it results in comments being expanded.
11685 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
11688 2002-10-24 Akim Demaille <akim@epita.fr>
11690 * data/yacc.c (m4_int_type): New.
11691 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
11692 char' as only yacc.c wants K&R portability.
11693 * data/glr.c (yysigned_char): Remove.
11694 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
11695 Reported by Quoc Peyrot.
11697 2002-10-23 Paul Eggert <eggert@twinsun.com>
11699 * src/main.c (main): With --trace=time, report times even if a
11700 non-fatal error occurs. Formerly, the times were reported in some
11701 such cases but not in others.
11702 * src/reader.c (reader): Just return if a complaint has been issued,
11703 instead of exiting, so that 'main' can report times.
11705 2002-10-22 Akim Demaille <akim@epita.fr>
11707 * src/system.h: Include sys/types.
11708 Reported by Bert Deknuydt.
11710 2002-10-23 Paul Eggert <eggert@twinsun.com>
11712 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
11713 Suggested by Art Haas.
11715 2002-10-22 Paul Eggert <eggert@twinsun.com>
11717 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
11718 decl; not needed any more.
11719 * src/main.c (main): Use return to exit, undoing yesterday's change.
11720 The last OS that we could find where this wouldn't work is
11721 SunOS 3.5, and that's too old to worry about now.
11723 * data/glr.c (struct yyltype): Define members even when not
11724 doing locations. This is more consistent with yacc.c, and it
11725 works around the following bug reports:
11726 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
11727 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
11729 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
11730 @acronym consistently. Standardize on "Yacc" instead of "YACC",
11731 "Algol" instead of "ALGOL". Give a bit more history about BNF.
11733 2002-10-22 Akim Demaille <akim@epita.fr>
11735 * data/README: New.
11737 2002-10-21 Paul Eggert <eggert@twinsun.com>
11739 Be consistent about 'bool'; the old code used an enum in one
11740 module and an int in another, and this violates the C standard.
11741 * m4/stdbool.m4: New file, from coreutils 4.5.3.
11742 * configure.ac (AC_HEADER_STDBOOL): Add.
11743 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
11744 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
11745 * src/symtab.c (hash_compare_symbol_t): Likewise.
11746 * src/system.h (bool, false, true): Use a definition consistent
11747 with ../lib/hash.c. All uses changed.
11749 * src/complain.c (warning_issued): Renamed from warn_message_count,
11750 so that we needn't worry about integer overflow (!).
11751 Now of type bool. All uses changed.
11752 (complaint_issued): Renamed from complain_message_count; likewise.
11754 * src/main.c (main): Use exit to exit with failure.
11756 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
11757 rather than 1 and 0.
11758 * src/main.c (main): Likewise.
11759 * src/getargs.c (getargs): Likewise.
11760 * src/reader.c (reader): Likewise.
11762 * src/getarg.c (getargs): Remove duplicate code for
11763 "Try `bison --help'".
11765 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
11766 What was that "2" for?
11768 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
11769 * src/getargs.c (usage): Likewise.
11771 * src/getargs.c (getargs): When there are too few operands, report
11772 the last one. When there are too many, report the first extra
11773 one. This is how diffutils does it.
11775 2002-10-20 Paul Eggert <eggert@twinsun.com>
11777 Remove K&R vestiges.
11778 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
11779 * src/complain.c (VA_START): Remove. Assume prototypes.
11780 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
11781 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
11782 fatal): Assume prototypes.
11783 * src/complain.h: Assume prototypes.
11784 * src/system.h (PARAMS): Remove.
11785 Include <limits.h> unconditionally, since it's guaranteeed even
11786 for a freestanding C89 compiler.
11787 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
11788 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
11790 2002-10-20 Akim Demaille <akim@epita.fr>
11792 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
11793 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
11794 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
11795 (yyresolveStates, yyresolveAction, yyresolveStack)
11796 (yyprocessOneStack): Use them.
11797 (yy_reduce_print): New.
11798 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
11800 2002-10-20 Akim Demaille <akim@epita.fr>
11802 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
11803 arguments and output `void'.
11804 (b4_c_function): Rename as...
11805 (b4_c_function_def): this.
11806 (b4_c_function_decl, b4_c_ansi_function_def)
11807 (b4_c_ansi_function_decl): New.
11808 Change the interpretation of the arguments: before `int, foo', now
11810 * data/yacc.c (yyparse): Prototype and define thanks to these.
11811 Adjust b4_c_function_def uses.
11812 * data/glr.c (yyparse): Likewise, but ANSI only.
11814 2002-10-20 Akim Demaille <akim@epita.fr>
11816 * src/output.c (prepare): Move the definition of `tokens_number',
11817 `nterms_number', `undef_token_number', `user_token_number_max'
11819 (prepare_tokens): Here.
11820 (prepare_tokens): Rename as...
11821 (prepare_symbols): this.
11822 (prepare): Move the definition of `rules_number' to...
11823 (prepare_rules): here.
11824 (prepare): Move the definition of `last', `final_state_number',
11825 `states_number' to...
11826 (prepare_states): here.
11827 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
11829 2002-10-20 Akim Demaille <akim@epita.fr>
11831 * src/tables.h, src/tables.c, src/output.c: Comment changes.
11833 2002-10-20 Akim Demaille <akim@epita.fr>
11835 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
11838 2002-10-20 Akim Demaille <akim@epita.fr>
11840 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.

11846 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
11849 2002-10-19 Paul Eggert <eggert@twinsun.com>
11851 Do not create a temporary file, as that involves security and
11852 cleanup headaches. Instead, use a pair of pipes.
11853 Derived from a suggestion by Florian Krohm.
11854 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
11855 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
11856 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
11857 (BISON_PREREQ_SUBPIPE): Add.
11858 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
11859 Add subpipe.h, subpipe.c.

11867 Check for pipe I/O error.
11868 * src/scan-skel.l (readpipe): Remove decl.
11869 (scan_skel): New function, to be used in place of m4_invoke.
11870 Read from stream rather than file.
11872 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
11873 float, as this generates a warning on Solaris 8 + GCC 3.2 with
11874 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
11875 this generates a more-accurate value anyway.
11877 * lib/timevar.c (timervar_accumulate): Rename locals to
11878 avoid confusion with similarly-named more-global.
11879 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
11881 * src/output.c (prepare): Use xstrdup to convert char const *
11882 to char *, to avoid GCC warning.
11884 2002-10-19 Akim Demaille <akim@epita.fr>
11886 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
11887 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
11888 Use them to have `calc.y' ready for %pure-parser.
11889 * data/yacc.c (YYLEX): Pass a yylex return type to
11890 b4_c_function_call.
11892 2002-10-19 Akim Demaille <akim@epita.fr>
11894 Prototype support of %lex-param and %parse-param.
11896 * src/parse-gram.y: Add the definition of the %lex-param and
11897 %parse-param tokens, plus their rules.
11898 Drop the `_' version of %glr-parser.
11900 * src/scan-gram.l (INITIAL): Scan them.
11901 * src/muscle_tab.c: Comment changes.
11902 (muscle_insert, muscle_find): Rename `pair' as `probe'.
11903 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
11904 (muscle_entry_s): The `value' member is no longer const.
11905 Adjust all dependencies.
11906 * src/muscle_tab.c (muscle_init): Adjust: use
11907 MUSCLE_INSERT_STRING.
11908 Initialize the obstack earlier.
11909 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
11910 (muscle_pair_list_grow): New.
11911 * data/c.m4 (b4_c_function_call, b4_c_args): New.
11912 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
11913 * tests/calc.at: Use %locations, not --locations.
11914 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
11916 2002-10-19 Akim Demaille <akim@epita.fr>
11918 * src/getargs.c (usage): Take status as argument and exit
11920 Report the traditional `Try ... --help' message when status != 0.
11921 (usage, version): Don't take a FILE * as arg, it is pointless.
11922 (getargs): When there is an incorrect number of arguments, make it
11923 an error, and report it GNUlically thanks to `usage ()'.
11925 2002-10-18 Paul Eggert <eggert@twinsun.com>
11927 * data/glr.c (yyreportParseError): Don't assume that sprintf
11928 yields the length of the printed string, as this is not true
11929 on SunOS 4.1.4. Reported by Peter Klein.
11931 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
11932 * tests/conflicts.at (%nonassoc and eof): Likewise.
11933 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
11935 2002-10-17 Akim Demaille <akim@epita.fr>
11937 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
11938 * src/getargs.c (trace_types, trace_args): Adjust.
11939 * src/reader.c (grammar_current_rule_prec_set)
11940 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
11941 Standardize error messages.
11942 And s/@prec/%prec/!
11943 (reader): Use trace_flag to enable scanner/parser debugging,
11944 instead of an adhoc scheme.
11945 * src/scan-gram.l: Remove trailing debugging code.
11947 2002-10-16 Paul Eggert <eggert@twinsun.com>
11949 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
11952 * NEWS: Officially drop support for building Bison with K&R C,
11953 since it didn't work anyway and it's not worth worrying about.
11954 * Makefile.maint (wget_files): Remove ansi2knr.c.
11955 (ansi2knr.c-url_prefix): Remove.
11956 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
11957 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11958 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
11960 2002-10-15 Paul Eggert <eggert@twinsun.com>
11962 Stop using the "enum_" trick for K&R-style function definitions;
11963 it confused me, and I was the author! Instead, assume that people
11964 who want to use K&R C compilers (when using these modules in GCC,
11965 perhaps?) will run ansi2knr.
11967 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
11968 All uses of "enum_" changed to "enum ".
11969 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
11970 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11972 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

11979 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
11980 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
11981 Use function prototypes; this removes the need for declaring
11982 static functions simply to provide their prototypes.
11983 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

12049 2002-10-14 Akim Demaille <akim@epita.fr>
12051 * src/tables.c (table_ninf_remap): base -> tab.
12052 Reported by Matt Rosing.
12054 2002-10-14 Paul Eggert <eggert@twinsun.com>
12056 * tests/action.at, tests/calc.at, tests/conflicts.at,
12057 tests/cxx-type.at, tests/headers.at, tests/input.at,
12058 tests/regression.at, tests/synclines.at, tests/torture.at:
12059 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12060 so that the tests still work even if POSIXLY_CORRECT is set.
12061 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12063 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12064 for portability to K&R hosts. Fix typo: signed char is guaranteed
12065 only to 127, not to 128.
12066 * data/glr.c (yysigned_char): New type.
12067 * data/yacc.c (yysigned_char): Likewise.
12068 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12070 2002-10-13 Paul Eggert <eggert@twinsun.com>
12072 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12073 true due to limited range of data type" warning from GCC.
12075 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12076 by wrapping enum yytokentype's definition inside #ifndef
12077 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12079 2002-10-13 Akim Demaille <akim@epita.fr>
12081 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12082 Un yy- yyrhs to avoid the name clash with the global YYRHS.
12084 2002-10-13 Akim Demaille <akim@epita.fr>
12086 * Makefile.maint: Update from Autoconf 2.54.
12087 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
12089 2002-10-13 Akim Demaille <akim@epita.fr>
12091 * src/print.c (print_state): Separate the list of solved conflicts
12092 from the other items.
12093 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
12095 2002-10-13 Akim Demaille <akim@epita.fr>
12097 Let nondeterministic skeletons be usable with deterministic
12100 With the patch, GAWK compiled by GCC without -O2 passes its test
12101 suite using a GLR parser driven by LALR tables. It fails with -O2
12102 because `struct stat' gives two different answers on my machine:
12103 88 (definition of an auto var) and later 96 (memset on this var).
12104 Hence the stack is badly corrumpted. The headers inclusion is to
12105 blame: if I move the awk.h inclusion before GLR's system header
12106 inclusion, the two struct stat have the same size.
12108 * src/tables.c (pack_table): Always create conflict_table.
12109 (token_actions): Always create conflict_list.
12110 * data/glr.c (YYFLAG): Remove, unused.
12112 2002-10-13 Akim Demaille <akim@epita.fr>
12114 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12116 (VALGRIND, GXX): New.
12117 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12118 * tests/bison.in: Run $PREBISON a pre-command.
12119 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12120 (maintainer-check-g++): New.
12121 * Makefile.am (maintainer-check): New.
12123 2002-10-13 Akim Demaille <akim@epita.fr>
12125 * data/glr.c: Formatting changes.
12126 Tweak some trace messages to match yacc.c's.
12128 2002-10-13 Akim Demaille <akim@epita.fr>
12130 GLR parsers sometimes raise parse errors instead of performing the
12132 Reported by Charles-Henry de Boysson.
12134 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12135 check the length of the traces when %glr.
12136 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12138 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12140 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12141 (yyltype): Remove the yy prefix from the member names.
12142 (yytable): Complete its comment.
12143 (yygetLRActions): Map error action number from YYTABLE from
12145 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12146 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12147 not satisfying as we could compare an YYACTION computed from
12148 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12149 only value for error actions.
12150 (yyreportParseError): In verbose parse error messages, don't issue
12151 `error' in the list of expected tokens.
12152 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12153 next action to perform to match glr.c's decoding.
12154 (yytable): Complete its comment.
12156 2002-10-13 Paul Eggert <eggert@twinsun.com>
12158 Fix problem reported by Henrik Grubbstroem in
12159 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12160 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12161 because the Bison parser reads the second action before reducing
12163 * src/scan-gram.l (rule_length): New static var.
12164 Use it to keep track of the rule length in the scanner, since
12165 we can't expect the parser to be in lock-step sync with the scanner.
12166 (handle_action_dollar, handle_action_at): Use this var.
12167 * tests/actions.at (Exotic Dollars): Test for the problem.
12169 2002-10-12 Paul Eggert <eggert@twinsun.com>
12171 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12172 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12173 Include <sys/time.h> when checking for clock_t and struct tms.
12174 Use same include order as source.
12175 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12176 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12178 * lib/timevar.c: Update copyright date and clarify comments.
12179 (get_time) [IN_GCC]: Keep the GCC version for reference.
12181 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
12182 GCC version as of today, then merge Bison's changes.
12183 Change "GCC" to "Bison" in copyright notice. timevar.def's
12184 author is Akim, so change that too.
12186 * src/reader.c (grammar_current_rule_check):
12187 Don't worry about the default action if $$ is untyped.
12188 Prevents bogus warnings reported by Jim Gifford in
12189 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
12191 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
12192 * data/glr.c, data/lalr1.cc, data/yacc.c:
12193 Output token definitions before the first part of user declarations.
12194 Fixes compatibility problem reported by Jim Gifford for kbd in
12195 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
12197 2002-10-11 Paul Eggert <eggert@twinsun.com>
12199 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
12200 (yyparse): here. This undoes some of the 2002-07-25 change.
12201 Compatibility problem reported by Ralf S. Engelschall with
12202 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
12204 2002-10-11 Akim Demaille <akim@epita.fr>

12217 Portability fixes for bitsets; this also avoids several GCC
12220 * lib/abitset.c: Include <stddef.h>, for offsetof.
12221 * lib/lbitset.c: Likewise.
12223 * lib/abitset.c (abitset_bytes): Return a size that is aligned
12224 properly for vectors of objects. Do not assume that adding a
12225 header size to a multiple of a word size yields a value that is
12226 properly aligned for the whole union.
12227 * lib/bitsetv.c (bitsetv_alloc): Likewise.
12229 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
12230 unique names for structures.
12231 * lib/ebitset.c (ebitset_bytes): Likewise.
12232 * lib/lbitset.c (lbitset_bytes): Likewise.
12234 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
12235 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
12236 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
12237 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
12238 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
12239 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
12240 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
12241 to improve the type-checking that GCC can do.
12242 * lib/bitset.c (bitset_op4_cmp): Likewise.
12243 * lib/bitset_stats.c (bitset_stats_count,
12244 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
12245 bitset_stats_copy, bitset_stats_disjoint_p,
12246 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
12247 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
12248 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
12249 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
12250 bitset_stats_and_or_cmp, bitset_stats_andn_or,
12251 bitset_stats_andn_or_cmp, bitset_stats_or_and,
12252 bitset_stats_or_and_cmp): Likewise.
12253 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
12254 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
12255 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
12256 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
12258 * lib/abitset.h: Include bitset.h, not bbitset.h.
12259 * lib/ebitset.h: Likewise.
12260 * lib/lbitset.h: Likewise.
12262 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
12263 All instances of parameters of type enum bitset_opts are now of
12264 type enum_bitset_opts, to conform to the C Standard, and similarly
12265 for enum_bitset_type.
12266 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
12267 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
12269 Do not use "struct bitset_struct" to mean different things in
12270 different modules. Not only is this confusing, it violates
12271 the C Standard, which requires that structure types in different
12272 modules must be compatible if one is to be passed to the other.
12273 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12274 All instances of "struct bitset_struct *" replaced with "bitset".
12275 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
12276 (union bitset_union, struct abitset_struct, struct ebitset_struct,
12277 struct lbitset_struct, struct bitset_stats_struct): New types.
12278 All uses of struct bitset_struct changed to union bitset_union,
12280 * lib/abitset.c (struct abitset_struct, abitset,
12281 struct bitset_struct): Remove.
12282 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
12283 struct bitset_struct): Remove.
12284 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
12285 bitset_struct): Remove.
12286 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
12289 Do not call a function of type T using a call that assumes the
12290 function is of a different type U. Standard C requires that a
12291 function must be called with a type that is compatible with its
12293 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12295 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12297 * lib/ebitset.c (PFV): Remove.
12298 * lib/lbitset.c (PFV): Likewise.
12299 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
12300 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
12302 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.

12305 lbitset_xor): New functions.
12306 (lbitset_vtable): Use them.
12308 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
12311 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
12313 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
12314 Use offsetof, for simplicity.
12316 2002-10-06 Paul Eggert <eggert@twinsun.com>
12318 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
12319 the same width as int. This reapplies a hunk of the 2002-08-12 patch
12320 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
12321 which was inadvertently undone by the 2002-09-30 patch.
12322 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
12323 the same width as int.
12325 2002-10-04 Paul Eggert <eggert@twinsun.com>
12329 * configure.ac (AC_INIT), NEWS: Increment version number.
12331 * doc/bison.texinfo: Minor spelling, grammar, and white space
12333 (Symbols): Mention that any negative value returned from yylex
12334 signifies end-of-input. Warn about negative chars. Mention
12335 the portable Standard C character set.
12337 The GNU coding standard says CFLAGS and YFLAGS are reserved
12338 for the installer to set.
12339 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
12340 * src/Makefile.am (AM_CFLAGS): Likewise.
12341 (AM_YFLAGS): Renamed from YFLAGS.
12343 Fix some MAX and MIN problems.
12344 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
12345 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
12346 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
12347 * src/reader.c (reader): Use it.
12349 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
12350 POSIX 1003.1-2001 has removed fgrep.
12352 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
12354 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
12355 interpreted as signed.

12427 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,

12625 PROTOTYPES to check for prototypes, and "defined __STDC__" to
12628 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not

12697 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
12698 exit status as failure, not just exit status 1. Sun C exits
12699 with status 2 sometimes.

12869 parsers now contain `reduce 0' as default reduction.

12920 token_translations instead of `0'.
12921 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
12923 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
12924 for the time being: %locations ought to provide it to yyerror.

12928 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

12943 Handle the `- 1' part in rule numbers from/to item numbers.

14584 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
14585 etc. instead of 10, 20, 30 (which was used to `jump' over error
14586 (256) and undefined (2)).
14588 2002-04-22 Akim Demaille <akim@epita.fr>

14625 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
14626 full stderr, and strip it according to the bison options, instead

14629 Adjust all the invocations.
14630 Add an invocation exercising the error token.
14631 Add an invocation demonstrating a stupid error message.
14632 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

14650 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
14651 `user_token_number_max'.

14693 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
14694 passes, but produces negative #line number, once fixed, GCC is

14895 2002-04-07 Akim Demaille <akim@epita.fr>
14897 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
14898 lacking `+ 1' to nrules, Bison reported as useless a token if it
14899 was used solely to set the precedence of the last rule...
14901 2002-04-07 Akim Demaille <akim@epita.fr>
14903 * data/bison.c++, data/bison.simple: Don't output the current file
14904 name in #line, to avoid useless diffs between two identical
14905 outputs under different names.

14909 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

14925 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
14926 RHS, instead of being an index in RITEMS.
14928 2002-04-04 Paul Eggert <eggert@twinsun.com>
14930 * doc/bison.texinfo: Update copyright date.
14931 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

15069 * src/closure.c, src/conflicts.c, src/lalr.c, src/print.c,
15070 * src/reduce.c: Remove the `bitset_zero's following the
15071 `bitset_create's, as now it is performed by the latter.
15073 2002-03-04 Akim Demaille <akim@epita.fr>
15075 * lib/bitset.c, lib/bitset.h, lib/bitsetv.c, lib/bitsetv.h,

15086 2002-03-04 Akim Demaille <akim@epita.fr>
15088 * src/lex.c (parse_percent_token): Be sure to 0-end token_buffer
15090 Reported by Benoit Perrot.
15092 2002-03-04 Akim Demaille <akim@epita.fr>
15094 Use bitset operations when possible, not loops over bits.
15096 * src/conflicts.c (set_conflicts, count_sr_conflicts): Use
15098 * src/print.c (print_reductions): Use bitset_and, bitset_andn.
15099 * src/reduce.c (useless_nonterminals): Formatting changes.
15100 * src/warshall.c (TC): Use bitset_or.
15102 2002-03-04 Akim Demaille <akim@epita.fr>
15104 * src/lalr.h, src/lalr.c (tokensetsize): Remove, unused.
15105 * src/system.h (BITS_PER_WORD, WORDSIZE, SETBIT, RESETBIT, BITISSET):

15110 * src/lalr.c (F): Now a bitset*.
15111 Adjust all dependencies.

15115 * src/conflicts.c (shiftset, lookaheadset): Now bitset.
15116 Adjust all dependencies.

15120 * src/L0.c, src/LR0.h (nstates): Be size_t.
15121 Adjust comparisons (signed vs unsigned).

15154 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
15156 * data/bison.c++: Merge the two generated headers. Insert a copyright
15157 notice in each output file.
15159 2002-02-28 Akim Demaille <akim@epita.fr>
15161 * data/bison.c++: Copy the prologue of bison.simple to fetch
15162 useful M4 definitions, such as b4_header_guard.
15164 2002-02-25 Akim Demaille <akim@epita.fr>
15166 * src/getargs.c (version): Give the name of the authors, and use a
15167 translator friendly scheme for the bgr
15170 2002-02-25 Akim Demaille <akim@epita.fr>
15172 * src/output.c (header_output): Remove, now handled completely via
15175 2002-02-25 Akim Demaille <akim@epita.fr>
15177 * m4/m4.m4: New, from CVS Autoconf.
15178 * configure.in: Invoke it.

15187 * src/output.c (output_skeleton): Use mkstemp to create a real
15189 Move the filling of `skeleton' and its muscle to...
15191 (output): Move the definition of the prologue muscle to...
15193 * src/system.h (DEFAULT_TMPDIR): New.
15195 2002-02-14 Paul Eggert <eggert@twinsun.com>
15197 Remove the support for C++ namespace cleanliness; it was
15198 causing more problems than it was curing, since it didn't work
15199 properly on some nonstandard C++ compilers. This can wait
15200 for a proper C++ parser.
15202 * NEWS: Document this.
15203 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
15204 of C++, as it's treated like C now.
15205 * src/bison.simple (YYSTD): Remove.
15206 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
15207 Treat C++ just like Standard C instead of trying to support
15208 namespace cleanliness.

15212 * tests/regression.at (else): Adjust to Andreas' change.
15214 2002-02-14 Akim Demaille <akim@epita.fr>
15216 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
15218 2002-02-13 Andreas Schwab <schwab@suse.de>
15220 * src/output.c (output_rule_data): Don't output NULL, it might
15221 not be defined yet.
15223 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
15225 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
15226 (Copyright notice): Update.
15228 2002-02-11 Akim Demaille <akim@epita.fr>
15230 * tests/regression.at (%nonassoc and eof): Don't include
15231 nonportable headers.
15233 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
15235 * data/bison.c++: Correct error recovery. Make the user able to
15236 initialize the starting location.
15238 2002-02-07 Akim Demaille <akim@epita.fr>
15240 * tests/input.at: New.
15242 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15244 * data/bison.c++: Replace some direct m4 expansions by constants. Be
15245 more consistent when naming methods and variables. Put preprocessor
15246 directives around tables only needed for debugging.
15248 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15250 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
15252 (yy::b4_name::parse): Use print_.
15254 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15256 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
15258 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
15260 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
15262 (yy::b4_name::parse): Build verbose error messages, and use error_.
15264 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15266 * data/bison.c++: Fix m4 quoting in comments.
15268 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
15270 * data/bison.c++: Adjust the parser code. Fix some muscles that were
15271 not expanded by m4.
15273 2002-02-05 Akim Demaille <akim@epita.fr>
15275 * data/bison.c++: Adjust to the M4 back end.
15276 More is certainly needed.
15278 2002-02-05 Akim Demaille <akim@epita.fr>
15280 Give a try to M4 as a back end.
15282 * lib/readpipe.c: New, from wdiff.
15283 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
15285 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
15286 specific values. Now it is m4 that performs the lookup.
15287 * src/parse-skel.y: Remove.
15288 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
15289 * src/output.c (actions_output, guards_output)
15290 (token_definitions_output): No longer keeps track of the output
15291 line number, hence remove the second argument.
15292 (guards_output): Check against the guard member of a rule, not the
15295 (output_skeleton): Don't look for the skeleton location, let m4 do
15297 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
15299 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
15300 (prepare): Given that for the time being changesyntax is not
15301 usable in M4, rename the muscles using `-' to `_'.
15302 Define `defines_flag', `output_parser_name' and `output_header_name'.
15303 * src/output.h (actions_output, guards_output)
15304 (token_definitions_output): Adjust prototypes.
15305 * src/scan-skel.l: Instead of scanning the skeletons, it now
15306 processes the output of m4: `__oline__' and `#output'.
15307 * data/bison.simple: Adjust to be used by M4(sugar).
15308 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
15310 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
15311 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
15312 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
15313 shamelessly stolen from CVS Autoconf.
15315 2002-02-05 Akim Demaille <akim@epita.fr>
15317 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
15318 * configure.in: Check for the declarations of free and malloc.
15319 * src/muscle_tab.c: Adjust.
15321 2002-02-05 Akim Demaille <akim@epita.fr>
15323 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
15324 which have no values.
15326 2002-02-05 Akim Demaille <akim@epita.fr>
15328 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
15331 2002-01-29 Paul Eggert <eggert@twinsun.com>
15333 * src/bison.simple (YYSIZE_T): Do not define merely because
15334 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
15335 On some platforms, <alloca.h> does not declare YYSTD (size_t).
15337 2002-01-27 Akim Demaille <akim@epita.fr>
15339 Fix `%nonassoc and eof'.
15341 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
15342 which were not properly copied! Replace
15343 memcpy (res->errs, src->errs, src->nerrs);
15345 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
15347 * tests/regression.at (%nonassoc and eof): Adjust to newest
15348 Autotest: `.' is not in the PATH.
15350 2002-01-27 Akim Demaille <akim@epita.fr>
15352 * tests/sets.at (AT_EXTRACT_SETS): New.
15353 (Nullable): Use it.
15356 2002-01-26 Akim Demaille <akim@epita.fr>
15358 * tests/actions.at, tests/calc.at, tests/headers.at,
15359 * tests/torture.at: Adjust to the newest Autotest which no longer
15360 forces `.' in the PATH.
15362 2002-01-25 Akim Demaille <akim@epita.fr>
15364 * tests/regression.at (%nonassoc and eof): New.
15365 Suggested by Robert Anisko.
15367 2002-01-24 Akim Demaille <akim@epita.fr>
15369 Bison dumps core when trying to complain about broken input files.
15370 Reported by Cris van Pelt.
15372 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
15373 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
15375 (Invalid inputs): Strengthen: exercise parse_percent_token.
15377 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
15379 * src/Makefile.am: Add bison.c++.
15380 * src/bison.c++: New skeleton.
15382 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
15386 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
15388 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
15390 2002-01-20 Marc Autret <marc@gnu.org>
15392 * src/files.c (compute_output_file_names): Fix
15394 2002-01-20 Marc Autret <marc@gnu.org>
15396 * tests/output.at: New test.
15397 * src/files.c (compute_base_names): Don't map extensions when
15398 the YACC flag is set, use defaults.
15399 Reported by Evgeny Stambulchik.
15401 2002-01-20 Marc Autret <marc@gnu.org>
15403 * src/system.h: Need to define __attribute__ away for non-GCC
15404 compilers as well (i.e., the vendor C compiler).
15405 Suggested by Albert Chin-A-Young.
15407 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
15409 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
15410 canonical definition.
15411 * src/system.h: Use the canonical definition for PARAMS (avoids
15412 a conflict with the macro from lib/hash.h).
15414 2002-01-11 Akim Demaille <akim@epita.fr>
15416 * configure.in: Use AC_FUNC_STRNLEN.
15417 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
15419 2002-01-09 Akim Demaille <akim@epita.fr>
15421 * src/files.c, src/files.h (output_infix): New.
15422 (tab_extension): Remove.
15423 (compute_base_names): Compute the former, drop the latter.
15424 * src/output.c (prepare): Insert the muscles `output-infix', and
15426 * src/parse-skel.y (string, string.1): New.
15427 (section.header): Use it.
15428 (section.yacc): Remove.
15429 (prefix): Remove too.
15430 * src/scan-skel.l: Adjust.
15431 * src/bison.simple, src/bison.hairy: Adjust.
15433 2002-01-09 Akim Demaille <akim@epita.fr>
15435 * configure.in (WERROR_CFLAGS): Compute it.
15436 * src/Makefile.am (CFLAGS): Pass it.
15437 * tests/atlocal.in (CFLAGS): Idem.
15438 * src/files.c: Fix a few warnings.
15439 (get_extension_index): Remove, unused.
15441 2002-01-08 Akim Demaille <akim@epita.fr>
15443 * src/getargs.c (AS_FILE_NAME): New.
15444 (getargs): Use it to convert DOSish file names.
15445 * src/files.c (base_name): Rename as full_base_name to avoid
15446 clashes with `base_name ()'.
15447 (filename_split): New.
15448 (compute_base_names): N-th rewrite, using filename_split.
15450 2002-01-08 Akim Demaille <akim@epita.fr>
15452 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
15453 New, stolen from the Fileutils 4.1.
15454 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
15455 * configure.in: Check for the presence of memrchr, and of its
15458 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
15460 * lib/hash.h (__P): Added definition for this macro.
15461 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
15462 BUILT_SOURCES, to ensure they are generated first.
15463 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
15464 %error-verbose to allow bootstrapping with bison 1.30x.
15466 2002-01-06 Akim Demaille <akim@epita.fr>
15468 * src/reader.c (parse_braces): Don't fetch the next char, the
15469 convention is to fetch on entry.
15470 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
15471 'switch' without a following semicolon.
15472 * tests/regression.at (braces parsing): New.
15474 2002-01-06 Akim Demaille <akim@epita.fr>
15476 Bison is dead wrong in its RR conflict reports.
15478 * tests/torture.at (GNU Cim Grammar): New.
15479 * src/conflicts.c (count_rr_conflicts): Fix.
15481 2002-01-06 Akim Demaille <akim@epita.fr>
15483 Creating package.m4 from configure.ac causes too many problems.
15485 * tests/Makefile.am (package.m4): Create it by hand,
15486 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
15488 2002-01-06 Akim Demaille <akim@epita.fr>
15490 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
15493 2002-01-04 Paul Eggert <eggert@twinsun.com>
15495 * doc/bison.texinfo (Debugging):
15496 Remove YYSTDERR; it's no longer defined or used.
15497 Also, s/cstdio.h/cstdio/.
15499 2002-01-03 Akim Demaille <akim@epita.fr>
15501 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
15503 2002-01-03 Akim Demaille <akim@epita.fr>
15505 * src/parse-skel.y (process_skeleton): Don't bind the parser's
15506 tracing code to --trace, wait for a better --trace option, with
15509 2002-01-03 Akim Demaille <akim@epita.fr>
15511 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
15512 The ISO C++ standard is extremely clear about it: stderr is
15513 considered a macro, not a regular symbol (see table 94 `Header
15514 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
15515 Therefore std:: does not apply to it. It still does with fprintf.
15516 Also, s/cstdio.h/cstdio/.
15518 2002-01-03 Akim Demaille <akim@epita.fr>
15520 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
15521 for non system headers.
15523 2002-01-02 Akim Demaille <akim@epita.fr>
15525 Equip the skeleton chain with location tracking, runtime trace,
15526 pure parser and scanner.
15528 * src/parse-skel.y: Request a pure parser, locations, and prefix
15530 (%union): Having several members with the same type does not help
15531 type mismatches, simplify.
15532 (YYPRINT, yyprint): New.
15533 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
15534 (skel_error): this.
15536 * src/scan-skel.l: Adjust to these changes.
15537 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
15538 (LOCATION_PRINT, skel_control_t): New.
15540 2001-12-30 Akim Demaille <akim@epita.fr>
15542 * src/parse-skel.y: Get rid of the shift/reduce conflict:
15543 replace `gb' with BLANKS.
15544 * src/scan-skel.l: Adjust.
15546 2001-12-30 Akim Demaille <akim@epita.fr>
15548 * src/system.h: We don't need nor want bcopy.
15549 Throw away MS-DOS crap: we don't need getpid.
15550 * configure.in: We don't need strndup. It was even causing
15551 problems: because Flex includes the headers *before* us,
15552 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15554 * lib/xstrndup.c: New.
15555 * src/scan-skel.l: Use it.
15556 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
15557 * src/parse-skel.y: Use %directives instead of #defines.
15559 2001-12-30 Akim Demaille <akim@epita.fr>
15561 * src/skeleton.h: New.
15562 * src/output.c (output_parser, output_master_parser): Remove, dead
15564 * src/output.h (get_lines_number, actions_output, guards_output)
15565 (token_definitions_output): Prototype them.
15566 * src/parse-skel.y: Add the license notice.
15567 Include output.h and skeleton.h.
15568 (process_skeleton): Returns void, and takes a single parameter.
15569 * src/scan-skel.l: Add the license notice.
15570 Include skeleton.h.
15571 Don't use %option yylineno: it seems that then Flex imagines
15572 REJECT has been used, and therefore it won't reallocate its
15573 buffers (which makes no other sense to me than a bug). It results
15574 in warnings for `unused: yy_flex_realloc'.
15576 2001-12-30 Robert Anisko <robert.anisko@epita.fr>

15580 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
15581 (MUSCLE_INSERT_PREFIX): Move from here...
15583 * src/bison.hairy: Add a section directive. Put braces around muscle
15584 names. This parser skeleton is still broken, but Bison should not
15585 choke on a bad muscle 'syntax'.
15586 * src/bison.simple: Add a section directive. Put braces around muscle
15589 * src/files.h (strsuffix, stringappend): Add declarations.
15590 (tab_extension): Add declaration.
15591 (short_base_name): Add declaration.
15593 * src/files.c (strsuffix, stringappend): No longer static. These
15594 functions are used in the skeleton parser.
15595 (tab_extension): New.
15596 (compute_base_names): Use the computations done in this function
15597 to guess if the generated parsers should have '.tab' in their
15599 (short_base_name): No longer static.
15601 * src/output.c (output_skeleton): New.
15602 (output): Disable call to output_master_parser, and give a try to
15603 a new skeleton handling system.

15605 (token_definitions_output, get_lines_number): No longer static.
15607 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.

15612 * src/parse-skel.y: New file.
15613 * src/scan-skel.l: New file.
15615 2001-12-29 Akim Demaille <akim@epita.fr>
15617 %name-prefix is broken.
15619 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
15620 Adjust all dependencies.
15621 * tests/headers.at (export YYLTYPE): Strengthen this test: use
15624 Renaming yylval but not yylloc is not consistent. Now we do.
15626 * src/bison.simple: Prefix yylloc if used.
15627 * doc/bison.texinfo (Decl Summary): Document that.
15629 2001-12-29 Akim Demaille <akim@epita.fr>
15631 * doc/bison.texinfo: Promote `%long-directive' over
15633 Remove all references to fixed-output-files, yacc is enough.
15635 2001-12-29 Akim Demaille <akim@epita.fr>
15637 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
15638 user prologue. These are defaults.
15639 * tests/actions.at (Mid-rule actions): Make sure the user can
15640 define YYDEBUG and YYERROR_VERBOSE.
15642 2001-12-29 Akim Demaille <akim@epita.fr>
15644 * src/output.c (header_output): Don't forget to export YYLTYPE and
15646 * tests/headers.at (export YYLTYPE): New, make sure it does.
15647 * tests/regression.at (%union and --defines, Invalid CPP headers):
15649 * tests/headers.at: here.
15651 2001-12-29 Akim Demaille <akim@epita.fr>
15653 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
15655 2001-12-29 Akim Demaille <akim@epita.fr>
15657 * tests/actions.at (Mid-rule actions): Output on a single line
15658 instead of several.
15660 2001-12-29 Akim Demaille <akim@epita.fr>
15662 * doc/bison.texinfo: Formatting changes.
15664 2001-12-29 Akim Demaille <akim@epita.fr>
15666 Don't store the token defs in a muscle, just be ready to output it
15667 on command. Now possible via `symbols'. Fixes a memory leak.
15669 * src/output.c (token_definitions_output): New.
15670 (output_parser, header_output): Use it.
15671 * src/reader.c (symbols_save): Remove.
15673 2001-12-29 Akim Demaille <akim@epita.fr>
15675 * src/bison.simple: Do not provide a default for YYSTYPE and
15676 YYLTYPE before the user's prologue. Otherwise it's hardly... a
15679 2001-12-29 Akim Demaille <akim@epita.fr>
15681 Mid-rule actions are simply... ignored!
15683 * src/reader.c (readgram): Be sure to attach mid-rule actions to
15684 the empty-rule associated to the dummy symbol, not to the host
15686 * tests/actions.at (Mid-rule actions): New.
15688 2001-12-29 Akim Demaille <akim@epita.fr>
15692 * src/reader.c (reader): Free grammar.
15694 2001-12-29 Akim Demaille <akim@epita.fr>
15698 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
15699 since it allocates it for each state, although only one is needed.
15700 (allocate_storage): Do it here.
15702 2001-12-29 Akim Demaille <akim@epita.fr>
15704 * src/options.h, src/options.c (create_long_option_table): Rename
15706 (long_option_table_new): this, with a clearer prototype.
15707 (percent_table): Remove, unused,
15708 * src/getargs.c (getargs): Adjust.
15710 2001-12-29 Akim Demaille <akim@epita.fr>
15712 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

15716 2001-12-29 Akim Demaille <akim@epita.fr>
15718 * src/lalr.c (build_relations): Rename `states' as `states1'.
15719 Sorry, I don't understand exactly what it is, no better name...
15721 2001-12-29 Akim Demaille <akim@epita.fr>
15723 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
15724 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

15740 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

15746 Adjust all users to use symbols[i]->tag.
15748 2001-12-29 Akim Demaille <akim@epita.fr>
15750 * src/gram.h, src/gram.c (symbols): New, similar to state_table
15752 * src/reader.c (packsymbols): Fill this table.
15754 * src/conflicts.c (resolve_sr_conflict): Adjust.
15755 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
15757 Use symbols[i]->tag instead of tags[i].
15759 2001-12-29 Akim Demaille <akim@epita.fr>
15761 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
15762 In addition, put a comment in there, to replace...
15763 * tests/regression.at (%union and C comments): Remove.
15765 2001-12-29 Akim Demaille <akim@epita.fr>
15767 * tests/regression.at (Web2c Actions): Blindly move the actual
15768 output as expected output. The contents *seem* right to me, but I
15769 can't pretend reading perfectly parser tables... Nonetheless, all
15770 the other tests pass correctly, the table look OK, even though the
15771 presence of `$axiom' is to be noted: AFAICS it is useless (but
15774 2001-12-29 Akim Demaille <akim@epita.fr>
15776 * src/reader.c (readgram): Don't add the rule 0 if there were no
15777 rules read. In other words, add it _after_ having performed
15778 grammar sanity checks.
15779 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
15781 2001-12-29 Akim Demaille <akim@epita.fr>
15783 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
15784 visible, and some states have now a different number.
15786 2001-12-29 Akim Demaille <akim@epita.fr>
15788 * src/reader.c (readgram): Bind the initial rule's lineno to that
15790 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
15791 (Solved SR Conflicts): Adjust rule 0's line number.
15793 2001-12-29 Akim Demaille <akim@epita.fr>
15795 Fix the `GAWK Grammar' failure.
15797 * src/LR0.c (final_state): Initialize to -1 so that we do compute
15798 the reductions of the first state which was mistakenly confused
15799 with the final state because precisely final_state was initialized
15801 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
15802 now noticed by Bison.
15803 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
15804 have a reduction on $default.
15806 2001-12-29 Akim Demaille <akim@epita.fr>
15808 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
15810 * src/closure.c (print_closure): Likewise.
15811 * src/derives.c (print_derives): Likewise.
15812 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
15815 2001-12-29 Akim Demaille <akim@epita.fr>
15817 * src/lalr.c (lookaheads_print): New.
15818 (lalr): Call it when --trace-flag.
15819 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
15822 2001-12-29 Akim Demaille <akim@epita.fr>
15824 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
15825 when walking through ritem, even via rule->rhs.
15826 * src/reduce.c (dump_grammar, useful_production, reduce_output)
15827 (useful_production, useless_nonterminals): Likewise.
15828 (reduce_grammar_tables): Likewise, plus update nritems.
15829 * src/nullable.c (set_nullable): Likewise.
15830 * src/lalr.c (build_relations): Likewise.
15831 * tests/sets.at (Nullable): Adjust.
15832 Fortunately, now, the $axiom is no longer nullable.
15834 2001-12-29 Akim Demaille <akim@epita.fr>
15836 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

15839 * src/reduce.c (nonterminals_reduce): Likewise.
15840 * src/print_graph.c (print_graph): Likewise.

15842 * src/nullable.c (set_nullable): Likewise.
15844 2001-12-29 Akim Demaille <akim@epita.fr>
15846 * src/output.c: Comment changes.
15848 2001-12-27 Paul Eggert <eggert@twinsun.com>
15850 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
15851 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
15852 Sparc, as they were causing more porting problems than the
15853 (minor) performance improvement was worth.
15855 Also, catch up with 1.31's YYSTD.
15857 2001-12-27 Akim Demaille <akim@epita.fr>
15859 * src/output.c (output_gram): Rely on nritems, not the
15860 0-sentinel. See below.
15861 Use -1 as separator, not 0.
15862 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
15863 Rely on -1 as separator in yyrhs, instead of 0.
15864 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
15865 twice `Now at end of input', therefore there are two lines less to
15868 2001-12-27 Akim Demaille <akim@epita.fr>
15870 * tests/regression.at (Unresolved SR Conflicts):
15871 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
15874 2001-12-27 Akim Demaille <akim@epita.fr>
15876 * src/LR0.c (new_state): Recognize the final state by the fact it
15877 is reached by eoftoken.
15878 (insert_start_shifting_state, insert_eof_shifting_state)
15879 (insert_accepting_state, augment_automaton): Remove, since now
15880 these states are automatically computed from the initial state.
15881 (generate_states): Adjust.
15882 * src/print.c: When reporting a rule number to the user, substract
15883 1, so that the axiom rule is rule 0, and the first user rule is 1.
15884 * src/reduce.c: Likewise.
15885 * src/print_graph.c (print_core): For the time being, just as for
15886 the report, depend upon --trace-flags to dump the full set of
15888 * src/reader.c (readgram): Once the grammar read, insert the rule
15889 0: `$axiom: START-SYMBOL $'.
15890 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15891 number of the states has changed (the final state is no longer
15892 necessarily the last), catch up.
15894 2001-12-27 Akim Demaille <akim@epita.fr>
15896 Try to make the use of the eoftoken valid. Given that its value
15897 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
15898 is used instead of > 0 where appropriate, (ii), depend upon nritems
15899 instead of the 0-sentinel.
15901 * src/gram.h, src/gram.c (nritems): New.
15902 Expected to be duplication of nitems, but for the time being...
15903 * src/reader.c (packgram): Assert nritems and nitems are equal.
15904 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
15905 * src/closure.c (print_closure, print_fderives): Likewise.
15906 * src/gram.c (ritem_print): Likewise.
15907 * src/print.c (print_core, print_grammar): Likewise.
15908 * src/print_graph.c: Likewise.
15910 2001-12-27 Akim Demaille <akim@epita.fr>
15912 * src/main.c (main): If there are complains after grammar
15913 reductions, then output the report anyway if requested, then die.
15914 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15915 * src/reader.c (eoftoken): New.
15916 (parse_token_decl): If the token being defined has value `0', it
15918 (packsymbols): No longer hack `tags' to insert `$' by hand.
15919 Be sure to preserve the value of the eoftoken.
15920 (reader): Make sure eoftoken is defined.
15921 Initialize nsyms to 0: now eoftoken is created just like the others.
15922 * src/print.c (print_grammar): Don't special case the eof token.
15923 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15924 lie anyway, albeit pleasant.
15925 * tests/calc.at: Exercise error messages with eoftoken.
15926 Change the grammar so that empty input is invalid.
15927 Adjust expectations.
15928 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
15930 2001-12-27 Akim Demaille <akim@epita.fr>
15932 * configure.in: Check the protos of strchr ans strspn.
15933 Replace strchr if needed.
15934 * src/system.h: Provide the protos of strchr, strspn and memchr if
15936 * lib/strchr.c: New.
15937 * src/reader.c (symbols_save): Use strchr.
15939 2001-12-27 Akim Demaille <akim@epita.fr>
15941 * src/print.c, src/print_graph.c (escape): New.
15942 Use it to quote the TAGS outputs.
15943 * src/print_graph.c (print_state): Now errors are in red, and
15944 reductions in green.
15945 Prefer high to wide: output the state number on a line of its own.
15947 2001-12-27 Akim Demaille <akim@epita.fr>
15949 * src/state.h, src/state.c (reductions_new): New.
15950 * src/LR0.c (set_state_table): Let all the states have a
15951 `reductions', even if reduced to 0.
15952 (save_reductions): Adjust.

15970 2001-12-27 Akim Demaille <akim@epita.fr>
15972 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
15973 * src/print.c: here.
15974 (lookaheadset, shiftset): New, used as additional storage by
15976 (print_results): Adjust.
15977 (print_shifts, print_gotos, print_errs): New, extracted from...
15978 (print_actions): here.
15979 * src/print_graph.c (print_actions): Remove dead code.
15981 2001-12-27 Akim Demaille <akim@epita.fr>
15983 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
15986 2001-12-27 Akim Demaille <akim@epita.fr>
15988 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
15989 (build_relations): Adjust.
15991 2001-12-27 Akim Demaille <akim@epita.fr>
15993 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
15996 2001-12-27 Akim Demaille <akim@epita.fr>
15998 * src/reader.c (packgram): Catch nitems overflows.
16000 2001-12-27 Akim Demaille <akim@epita.fr>

16003 * src/output.c (output): Adjust.
16004 * src/reader.c (parse_braces): New, factoring...
16005 (copy_action, copy_guard): these two which are renamed as...
16006 (parse_action, parse_guard): these.
16007 As a voluntary consequence, using braces around guards is now
16010 2001-12-27 Akim Demaille <akim@epita.fr>
16012 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16013 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16015 (symbol_list_new): Adjust.
16016 (copy_action): action_line is the first line, not the last.
16017 (copy_guard): Just as for actions, store the `action' only, not
16018 the switch/case/break flesh.
16019 Don't parse the user action that might follow the guard, let...
16020 (readgram): do it, i.e., now, there can be an action after a
16022 In other words the guard is just explicitly optional.
16023 (packgram): Adjust.
16024 * src/output.c (guards_output): New.
16025 (output_parser): Call it when needed.
16026 (output): Also free the guard and attrs obstacks.
16027 * src/files.c, src/files.h (obstack_save): Remove.
16028 (output_files): Remove.
16029 As a result, if one needs the former `.act' file, using an
16030 appropriate skeleton which requires actions and guards is now
16032 * src/main.c (main): Adjust.
16033 * tests/semantic.at: New.
16034 * tests/regression.at: Use `input.y' as input file name.
16035 Avoid 8+3 problems by requiring input.c when the test needs the

16040 * src/reader.c (symbol_list_new): Be sure to initialize all the
16043 2001-12-27 Akim Demaille <akim@epita.fr>
16045 All the hacks using a final pseudo state are now useless.
16047 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16048 * src/lalr.c (nLA): New.
16049 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16050 instead of lookaheadsp from the pseudo state (nstate + 1).
16052 2001-12-27 Akim Demaille <akim@epita.fr>
16054 * src/output.c (action_row, token_actions): Use a state_t instead
16055 of a integer, and nlookaheads instead of the following state's

16062 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16063 (conflicts_print, print_reductions): Use a state_t instead of an
16064 integer when referring to a state.
16065 As much as possible, depend upon nlookaheads, instead of the
16066 `lookaheadsp' member of the following state (since lookaheads of
16067 successive states are successive, the difference between state n + 1
16068 and n served as the number of lookaheads for state n).
16069 * src/lalr.c (add_lookback_edge): Likewise.
16070 * src/print.c (print_core, print_actions, print_state)
16071 (print_results): Likewise.

16076 2001-12-27 Akim Demaille <akim@epita.fr>
16078 * src/bison.hairy: Formatting/comment changes.
16080 Remove `register' indications.
16081 Add plenty of `static'.
16083 2001-12-27 Akim Demaille <akim@epita.fr>
16085 * src/output.c (prepare): Drop the muscle `ntbase' which
16086 duplicates ntokens.
16087 * src/bison.simple: Formatting/comment changes.
16088 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16089 is an undocumented synonym.
16091 2001-12-22 Akim Demaille <akim@epita.fr>
16093 * src/output.c (output_table_data): Change the prototype to use
16094 `int' for array ranges: some invocations do pass an int, not a
16096 Reported by Wayne Green.
16098 2001-12-22 Akim Demaille <akim@epita.fr>
16100 Some actions of web2c.y are improperly triggered.
16101 Reported by Mike Castle.
16103 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16104 * tests/regression.at (Web2c): Rename as...
16105 (Web2c Report): this.
16106 (Web2c Actions): New.
16108 2001-12-22 Akim Demaille <akim@epita.fr>
16110 Reductions in web2c.y are improperly reported.
16111 Reported by Mike Castle.
16113 * src/conflicts.c (print_reductions): Fix.
16114 * tests/regression.at (Web2c): New.
16116 2001-12-18 Akim Demaille <akim@epita.fr>
16118 Some host fail on `assert (!"foo")', which expands to
16119 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16120 Reported by Nelson Beebee.
16122 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16123 `#define it_succeeded 0' and `assert (it_succeeded)'.
16125 2001-12-17 Marc Autret <autret_m@epita.fr>
16127 * src/bison.simple: Don't hard code the skeleton line and filename.
16128 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16129 New line counter 'skeleton_line' (skeleton-line muscle).
16131 2001-12-17 Paul Eggert <eggert@twinsun.com>
16133 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16134 YYDEBUG must be defined to a nonzero value.
16136 * src/bison.simple (yytname): Do not assume that the user defines
16137 YYDEBUG to a properly parenthesized expression.
16139 2001-12-17 Akim Demaille <akim@epita.fr>
16141 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16142 nlookaheads is a new member.
16144 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16145 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16148 2001-12-17 Akim Demaille <akim@epita.fr>
16150 * src/files.h, src/files.c (open_files, close_files): Remove.
16151 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16153 * src/reader.c (reader): Do it.
16155 2001-12-17 Akim Demaille <akim@epita.fr>
16157 * src/conflicts.c (print_reductions): Formatting changes.
16159 2001-12-17 Akim Demaille <akim@epita.fr>
16161 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
16162 (flush_reduce): New.
16163 (resolve_sr_conflict): Adjust.
16165 2001-12-17 Akim Demaille <akim@epita.fr>
16167 * src/output.c (output_obstack): Be static and rename as...
16168 (format_obstack): this, to avoid any confusion with files.c's
16170 * src/reader.h (muscle_obstack): Move to...
16171 * src/output.h: here, since it's defined in output.c.
16173 2001-12-17 Akim Demaille <akim@epita.fr>
16175 * src/output.c (action_row, save_column, default_goto)
16176 (sort_actions, matching_state, pack_vector): Better variable
16179 2001-12-17 Akim Demaille <akim@epita.fr>
16181 * src/output.c: Various formatting changes.
16183 2001-12-17 Akim Demaille <akim@epita.fr>
16185 * src/files.c (output_files): Free the output_obstack.
16186 * src/main.c (main): Call print and print_graph conditionally.
16187 * src/print.c (print): Work unconditionally.
16188 * src/print_graph.c (print_graph): Work unconditionally.
16189 * src/conflicts.c (log_resolution): Output only if verbose_flag.
16191 2001-12-16 Marc Autret <autret_m@epita.fr>
16193 * src/output.c (actions_output): Fix. When we use %no-lines,
16194 there is one less line per action.
16196 2001-12-16 Marc Autret <autret_m@epita.fr>
16198 * src/bison.simple: Remove a useless #line directive.
16199 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
16200 * src/output.c (get_lines_number): New.
16201 (output_parser): Adjust, now takes care about the lines of a
16203 Fix line numbering.
16204 (actions_output): Computes the number of lines taken by actions.
16205 (output_master_parser): Insert new skeleton which is the name of
16206 the output parser file name.
16208 2001-12-15 Marc Autret <autret_m@epita.fr>
16210 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
16212 2001-12-15 Marc Autret <autret_m@epita.fr>
16214 * src/output.c (output_gram): Keep track of the hairy one.
16216 2001-12-15 Akim Demaille <akim@epita.fr>
16218 Make `make distcheck' work.
16220 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
16221 system.h which uses libgettext.h.
16223 2001-12-15 Akim Demaille <akim@epita.fr>
16225 * src/nullable.c (set_nullable): Useless rules must be skipped,
16226 otherwise, since we range over their symbols, we might look at a
16227 nonterminal which no longer ``exists'', i.e., it is not counted in
16228 `nvars', hence we overflow our arrays.
16230 2001-12-15 Akim Demaille <akim@epita.fr>
16232 The header can also be produced directly, without any obstack!
16235 * src/files.c, src/files.h (defines_obstack): Remove.
16236 (compute_header_macro): Global.
16237 (defines_obstack_save): Remove.
16238 * src/reader.c (parse_union_decl): No longer output to
16239 defines_obstack: its content can be found in the `stype' muscle
16241 (output_token_translations): Merge into...
16242 (symbols_output): this.
16244 (symbols_save): this.
16246 * src/output.c (header_output): New.
16249 2001-12-15 Akim Demaille <akim@epita.fr>
16251 * src/reader.c (parse_union_decl): Instead of handling two obstack
16252 simultaneously, use one to define the `stype' muscle, and use the
16253 value of the latter to fill defines_obstack.
16254 (copy_comment): Remove.
16255 (copy_comment2): Work for a single obstack.
16257 (copy_comment): this.
16259 2001-12-15 Akim Demaille <akim@epita.fr>
16261 * src/lex.c, src/lex.h (xgetc): No longer static.
16262 * src/reader.c (parse_union_decl): Revamp.
16264 2001-12-15 Akim Demaille <akim@epita.fr>
16266 Still making progress in separating Bison into (i) input, (ii)
16267 process, (iii) output: now we can directly output the parser file
16268 without using table_obstack at all.
16270 * src/files.c, src/files.h (table_obstack): Bye bye.
16271 (parser_file_name): New.
16272 * src/files.c (compute_output_file_names): Compute it.
16273 * src/output.c (actions_output, output_parser)
16274 (output_master_parser): To a file instead of an obstack.
16276 2001-12-15 Akim Demaille <akim@epita.fr>
16278 Attach actions to rules, instead of pre-outputting them to
16281 * src/gram.h (rule_t): action and action_line are new members.
16282 * src/reader.c (symbol_list): Likewise.
16283 (copy_action): Save the actions within the rule.
16284 (packgram): Save them in rule_table.
16285 * src/output.c (actions_output): New.
16286 (output_parser): Use it on `%%actions'.
16287 (output_rule_data): Don't free rule_table.
16289 (prepare): Don't save the `action' muscle.
16290 * src/bison.simple: s/%%action/%%actions/.
16292 2001-12-15 Akim Demaille <akim@epita.fr>
16294 * src/reader.c (copy_action): When --yacc, don't append a `;'
16295 to the user action: let it fail if lacking.
16296 Suggested by Arnold Robbins and Tom Tromey.
16298 2001-12-14 Akim Demaille <akim@epita.fr>
16300 * src/lex.c (literalchar): Simply return the char you decoded, non
16301 longer mess around with obstacks and int pointers.
16302 Adjust all callers.
16304 2001-12-14 Akim Demaille <akim@epita.fr>
16306 * src/lex.c (literalchar): Don't escape the special characters,
16307 just decode them, and keep them as char (before, eol was output as
16308 the 2 char string `\n' etc.).
16309 * src/output.c (output_rule_data): Use quotearg to output the
16312 2001-12-13 Paul Eggert <eggert@twinsun.com>
16314 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
16315 Do not infringe on the global user namespace when using C++.
16316 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
16317 All uses of `fprintf' and `stderr' changed.
16319 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
16321 2001-12-13 Akim Demaille <akim@epita.fr>
16323 The computation of nullable is broken: it doesn't handle empty
16326 * tests/torture.at (GNU AWK Grammar): New.
16327 * tests/sets.at (Nullable): New.
16328 * src/nullable.c (set_nullable): Instead of blindly looping over
16329 `ritems', loop over the rules, and then over their rhs's.
16331 Work around Autotest bugs.
16333 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
16334 frame, because Autotest understand lines starting with a `+' as
16335 traces from the shell. Then, they are not processed properly.
16336 Admittedly an Autotest bug, but we don't have time to wait for
16337 Autotest to catch up.
16338 * tests/regression.at (Broken Closure): Adjust to the new table
16341 * tests/sets.at: here.
16343 2001-12-13 Akim Demaille <akim@epita.fr>
16345 * src/closure.c (closure): Use nrules instead of playing tricks
16346 with BITS_PER_WORD.
16348 2001-12-13 Akim Demaille <akim@epita.fr>
16350 * src/print.c (print_actions): Output the handling of `$' as the
16351 traces do: shifting the token EOF. Before EOF was treated as a
16353 * tests/regression.at: Adjust some tests.
16354 * src/print_graph.c (print_core): Complete the set of items via
16355 closure. The next-to-final and final states are still unsatisfying,
16356 but that's to be addressed elsewhere.
16357 No longer output the rule numbers, but do output the state number.
16358 A single loop for the shifts + gotos is enough, but picked a
16359 distinct color for each.
16360 (print_graph): Initialize and finalize closure.
16362 2001-12-13 Akim Demaille <akim@epita.fr>
16364 * src/reader.c (readgram): Remove dead code, an strip useless
16366 (get_type): Remove, unused.
16368 2001-12-12 Akim Demaille <akim@epita.fr>
16370 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
16371 on that of lib/error.c.
16373 2001-12-12 Akim Demaille <akim@epita.fr>
16375 Some hosts don't like `/' in includes.
16377 * src/system.h: Include libgettext.h without qualifying the path.
16378 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
16381 2001-12-11 Marc Autret <autret_m@epita.fr>
16383 * src/output.c (output_parser): Remove useless muscle.
16385 2001-12-11 Marc Autret <autret_m@epita.fr>
16387 * src/bison.simple: Remove #line just before %%epilogue. It
16388 is now handled in ...
16389 * src/reader.c (read_additionnal_code): Add the output of a
16390 #line for the epilogue.
16392 2001-12-10 Marc Autret <autret_m@epita.fr>
16394 * src/reader.c (copy_definition): Re-use CPP-outed code which
16395 replace precedent remove.
16396 * src/bison.simple: Remove #line before %%prologue because
16397 %%input-line is wrong at this time.
16399 2001-12-10 Marc Autret <autret_m@epita.fr>
16401 * src/reader.c (symbols_output): Clean up.
16402 * src/output.c (output_gram, output): Clean up.
16404 2001-12-10 Akim Demaille <akim@epita.fr>
16406 * src/lalr.c (initialize_lookaheads): New. Extracted from...
16407 * src/LR0.c (set_state_table): here.
16408 * src/lalr.c (lalr): Call it.
16410 2001-12-10 Akim Demaille <akim@epita.fr>
16412 * src/state.h (shifts): Remove the `number' member: shifts are
16413 attached to state, hence no longer need to be labelled with a
16416 2001-12-10 Akim Demaille <akim@epita.fr>
16418 Now that states have a complete set of members, the linked list of
16419 shifts is useless: just fill directly the state's shifts member.
16421 * src/state.h (shifts): Remove the `next' member.
16422 * src/LR0.c (first_state, last_state): Remove.
16423 Adjust the callers.
16424 (augment_automaton): Don't look for the shifts that must be added
16425 a shift on EOF: it is those of the state we looked for! But now,
16426 since shifts are attached, it is no longer needed to looking
16427 merely by its id: its number.
16429 2001-12-10 Akim Demaille <akim@epita.fr>
16431 * src/LR0.c (augment_automaton): Better variable locality.
16432 Remove an impossible branch: if there is a state corresponding to
16433 the start symbol being shifted, then there is shift for the start
16434 symbol from the initial state.
16436 2001-12-10 Akim Demaille <akim@epita.fr>
16438 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
16439 only when appropriate: when insert_start_shifting_state' is not
16441 * tests/regression.at (Rule Line Numbers): Adjust.
16443 2001-12-10 Akim Demaille <akim@epita.fr>
16445 * src/LR0.c (augment_automaton): Now that all states have shifts,
16446 merge the two cases addition shifts to the initial state.
16448 2001-12-10 Akim Demaille <akim@epita.fr>
16450 * src/lalr.c (set_state_table): Move to...
16452 * src/lalr.c (lalr): Don't call it...
16453 * src/LR0.c (generate_states): do it.
16454 * src/LR0.h (first_state): Remove, only the table is used.
16456 2001-12-10 Akim Demaille <akim@epita.fr>
16458 * src/LR0.h (first_shift, first_reduction): Remove.
16459 * src/lalr.c: Don't use first_shift: find shifts through the
16462 2001-12-10 Akim Demaille <akim@epita.fr>
16464 * src/LR0.c: Attach shifts to states as soon as they are
16466 * src/lalr.c (set_state_table): Instead of assigning shifts to
16467 state, just assert that the mapping was properly done.
16469 2001-12-10 Akim Demaille <akim@epita.fr>
16471 * src/LR0.c (insert_start_shift): Rename as...
16472 (insert_start_shifting_state): this.
16473 (insert_eof_shifting_state, insert_accepting_state): New.
16474 (augment_automaton): Adjust.
16475 Better locality of the variables.
16476 When looking if the start_symbol is shifted from the initial
16477 state, using `while (... symbol != start_symbol ...)' sounds
16478 better than `while (... symbol < start_symbol ...)': If fail
16479 to see how the order between symbols could be relevant!
16481 2001-12-10 Akim Demaille <akim@epita.fr>
16483 * src/getargs.h: Don't declare `spec_name_prefix' and
16484 `spec_file_prefix', declared by src/files.h.
16485 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
16486 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
16487 * src/output.c (prepare): Adjust.
16488 * src/reader.c (symbols_output): Likewise.
16489 * src/vmsgetargs.c: Vaguely adjust, but who cares?
16491 2001-12-10 Akim Demaille <akim@epita.fr>
16493 * src/muscle_tab.c (muscle_init): NULL is a better default than
16496 2001-12-10 Akim Demaille <akim@epita.fr>
16498 * src/reader.c (reader): Calling symbols_output once is enough.
16500 2001-12-10 Akim Demaille <akim@epita.fr>
16502 Now that states have a complete set of members, the linked list of
16503 reductions is useless: just fill directly the state's reductions
16506 * src/state.h (struct reductions): Remove member `number' and
16508 * src/LR0.c (first_reduction, last_reduction): Remove.
16509 (save_reductions): Don't link the new reductions, store them in
16511 * src/lalr.c (set_state_table): No need to attach reductions to
16512 states, it's already done.
16513 * src/output.c (output_actions): No longer free the shifts, then
16514 the reductions, then the states: free all the states and their
16517 2001-12-10 Akim Demaille <akim@epita.fr>
16519 * src/options.c (OPTN, DRTV, BOTH): New.
16520 (option_table): Use them.
16522 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
16523 the job of system.h.
16524 * src/options.c: Don't include stdio.h and xalloc.h for the same
16527 2001-12-10 Akim Demaille <akim@epita.fr>
16529 * src/output.c (output, prepare): Make sure the values of the
16530 muscles `action' and `prologue' are 0-terminated.
16532 2001-12-10 Akim Demaille <akim@epita.fr>
16534 Clean up GCC warnings.
16536 * src/reader.c (copy_action): `buf' is not used.
16537 (parse_skel_decl): Be static.
16538 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
16539 * src/options.h (create_long_option_table): Have a real prototype.
16540 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
16541 (hash_delete_at): Return const void *.
16542 Adjust casts to preserve the const.
16544 2001-12-10 Akim Demaille <akim@epita.fr>
16546 * configure.in: Require 2.52g.
16547 M4 is not needed, but AUTOM4TE is.
16548 * m4/m4.m4: Remove.
16549 * tests/Makefile.am: Adjust.
16551 2001-12-10 Akim Demaille <akim@epita.fr>
16553 One structure for states is enough, even though theoretically
16554 there are LR(0) states and LALR(1) states.
16556 * src/lalr.h (state_t): Remove.
16557 (state_table): Be state_t **, not state_t *.
16558 * src/state.h (core, CORE_ALLOC): Rename as...
16559 (state_t, STATE_ALLOC): this.
16560 Add the LALR(1) members: shifts, reductions, errs.
16561 * src/LR0.c (state_table): Rename as...
16562 (state_hash): this, to avoid name clashes with the global
16564 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
16565 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
16567 2001-12-10 Akim Demaille <akim@epita.fr>
16569 Bison dumps core on bash.y.
16570 Reported by Pascal Bart.
16572 * src/warshall.c (bitmatrix_print): New.
16574 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
16575 j must be the outer loop.
16576 * tests/regression.at (Broken Closure): New.
16578 2001-12-05 Akim Demaille <akim@epita.fr>
16580 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
16582 Reported by Peter Hamorsky.
16584 2001-12-05 Akim Demaille <akim@epita.fr>
16586 * src/conflicts.c (err_table): Remove.
16587 (resolve_sr_conflict): Adjust.
16588 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
16590 (state_t.reductions, state_t.shifts): this.
16592 2001-12-05 Akim Demaille <akim@epita.fr>
16594 * src/reduce.c (reduce_grammar_tables): No longer disable the
16595 removal of useless rules via CPP but via `if (0)', so that the
16596 compiler still check the code is valid.
16597 For instance, it should have noticed `rline' no longer exists: use
16598 the `line' member of rule_t.
16599 * src/gram.c (dummy, rline): Remove, unused.
16601 2001-12-05 Akim Demaille <akim@epita.fr>
16603 * src/output.c (pack_vector): Use assert, not berror.
16604 * src/main.c (berror): Remove, unused.
16606 2001-12-05 Akim Demaille <akim@epita.fr>
16608 New experimental feature: if --verbose --trace output all the
16609 items of a state, not only its kernel.
16611 * src/print.c (print_core): If `trace_flag', then invoke closure
16612 before outputting the items of the state (print_core is no longer
16613 a correct name them).
16614 (print_results): Invoke new_closure/free_closure if needed.
16616 2001-12-05 Akim Demaille <akim@epita.fr>
16618 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
16619 * src/closure.c, src/closure.h (itemsetsize): Rename as...
16620 (nitemset): for consistency with the rest of the project.
16622 2001-12-05 Akim Demaille <akim@epita.fr>
16624 * src/closure.c (print_closure): Improve.
16625 (closure): Use it for printing input and output.
16627 2001-12-05 Akim Demaille <akim@epita.fr>
16629 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
16630 indexed by nonterminals.
16632 2001-12-05 Akim Demaille <akim@epita.fr>
16634 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
16636 * src/warshall.h: Remove accidental duplication of the content.

16650 2001-12-05 Akim Demaille <akim@epita.fr>
16652 * src/output.c (action_row): De-obfuscate
16653 using the good o' techniques: arrays not pointers, variable
16654 locality, BITISSET, RESETBIT etc.
16656 2001-12-05 Akim Demaille <akim@epita.fr>
16658 Pessimize the code to simplify it: from now on, all the states
16659 have a valid SHIFTS, which NSHIFTS is possibly 0.
16661 * src/LR0.c (shifts_new): Be global and move to..
16662 * src/state.c, src/state.h: here.
16663 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
16664 * src/print_graph: Adjust.
16666 2001-12-05 Akim Demaille <akim@epita.fr>
16668 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
16669 * src/conflicts.c: Use it.
16670 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
16671 incorrectly ``simplified''.
16673 2001-12-05 Akim Demaille <akim@epita.fr>
16675 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
16676 using the good o' techniques: arrays not pointers, variable
16677 locality, BITISSET, RESETBIT etc.
16679 2001-12-05 Akim Demaille <akim@epita.fr>
16681 * src/state.h (SHIFT_SYMBOL): New.

16711 2001-12-05 Akim Demaille <akim@epita.fr>
16713 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
16714 * src/lalr.c: Use them.
16716 2001-12-05 Akim Demaille <akim@epita.fr>
16718 * src/LR0.c (augment_automaton): Formatting changes.
16719 Better variable locality.

16723 * src/lalr.c (matrix_print): New.
16724 (transpose): Use it.

16729 * src/lalr.c (maxrhs): Move to...
16730 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
16731 * src/lalr.c (build_relations): Adjust.
16733 2001-12-05 Akim Demaille <akim@epita.fr>
16735 * src/lalr.c (transpose): Free the memory allocated to the
16736 argument, as it is replaced by the results by the unique caller.
16737 (build_relations): Merely invoke transpose: it handles the memory
16739 Improve variable locality.
16740 Avoid variables used as mere abbreviations.
16741 (compute_lookaheads): Use arrays instead of pointers.
16743 2001-12-05 Akim Demaille <akim@epita.fr>
16745 * src/lalr.c (initialize_F): Improve variable locality.
16746 Avoid variables used as mere abbreviations.
16748 2001-12-05 Akim Demaille <akim@epita.fr>
16750 * src/derives.c (print_derives): Display the ruleno.
16751 * src/lalr.c (initialize_F, transpose): Better variable locality

16759 2001-12-05 Akim Demaille <akim@epita.fr>
16761 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
16762 the handling of squeue.
16763 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16765 2001-12-05 Akim Demaille <akim@epita.fr>
16767 Because useless nonterminals are now kept alive (instead of being
16768 `destroyed'), we now sometimes examine them, and store information
16769 related to them. Hence we need to know their number, and adjust
16770 memory allocations.
16772 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
16774 * src/LR0.c (allocate_itemsets): The memory allocated to
16775 `symbol_count' was used for two different purpose: once to count
16776 the number of occurrences of each symbol, and later reassigned to
16777 `shift_symbol', containing the symbol that can be shifted from a
16779 Deobfuscate, i.e., allocate, use and free `symbol_count' here
16781 (new_itemsets): Allocate `shift_symbol' here.
16782 (allocate_itemsets): symbol_count includes useless nonterminals.
16783 Make room for them.
16784 (free_storage): Use `free', not `XFREE', for pointers that cannot
16787 2001-12-05 Akim Demaille <akim@epita.fr>
16789 * src/nullable.c (set_nullable): Deobfuscate the handling of
16791 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
16793 2001-12-05 Akim Demaille <akim@epita.fr>
16795 * src/gram.c, src/gram.h (ritem_print): New.
16796 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
16797 (This useless function was defined only to work around VMS linkers
16798 that can't handle compilation units with variables only).
16799 * src/reduce.c (dump_grammar): Use it to trace the construction of
16802 2001-12-04 Paul Eggert <eggert@twinsun.com>
16804 * src/bison.simple (union yyalloc): Change member names
16805 to be the same as the stack names.
16806 (yyparse): yyptr is now union yyalloc *, not char *.
16807 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
16808 and may generate better code on some machines.
16809 (yystpcpy): Use prototype if __STDC__ is defined, not just
16810 if __cplusplus is defined.
16812 2001-11-30 Akim Demaille <akim@epita.fr>
16814 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
16815 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
16816 Gettext doesn't compile cleanly, and dies with -Werror.
16817 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
16818 Include WARNING_CFLAGS here.
16819 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
16820 before being defined.
16822 2001-11-27 Paul Eggert <eggert@twinsun.com>
16824 * lib/quotearg.h (quotearg_n, quotearg_n_style):
16825 First arg is int, not unsigned.
16826 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
16827 (SIZE_MAX, UINT_MAX): New macros.
16828 (quotearg_n_options): Abort if N is negative.
16829 Avoid overflow check on hosts where size_t is 64 bits and int
16830 is 32 bits, as overflow is impossible there.
16831 Fix off-by-one typo that caused unnecessary reallocation.
16833 2001-11-29 Paul Eggert <eggert@twinsun.com>
16835 Name space cleanup in generated parser.
16837 * doc/bison.texinfo (Bison Parser): Discuss system headers
16838 and their effect on the user name space.
16840 * src/bison.simple:
16841 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
16842 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
16843 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
16845 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
16846 on user names when possible.
16848 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
16849 Simplify test for whather <alloca.h> exists.
16851 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
16853 (<stdio.h>): Include if YYDEBUG.
16855 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
16856 ! defined (yyoverflow) && ! defined (yymemcpy).
16858 (yymemcpy, yyparse): Rename local variables as needed so that
16859 they all begin with 'yy'.
16861 (yystrlen, yystpcpy): New functions.
16863 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
16866 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
16867 instead of relying on string.h functions. Use YYSTACK_ALLOC
16868 and YYSTACK_FREE instead of malloc and free.
16870 2001-11-30 Akim Demaille <akim@epita.fr>
16872 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
16873 before their first uses.

16880 2001-11-30 Akim Demaille <akim@epita.fr>
16882 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
16883 if body instead of `;' to pacify GCC's warnings.
16885 2001-11-30 Akim Demaille <akim@epita.fr>
16887 Instead of mapping the LHS of unused rules to -1, keep the LHS
16888 valid, but flag the rules as invalid.
16890 * src/gram.h (rule_t): `useful' is a new member.
16891 * src/print.c (print_grammar): Adjust.
16892 * src/derives.c (set_derives): Likewise.
16893 * src/reader.c (packgram, reduce_output): Likewise.
16894 * src/reduce.c (reduce_grammar_tables): Likewise.
16895 * tests/reduce.at (Underivable Rules, Useless Rules): New.
16897 2001-11-30 Akim Demaille <akim@epita.fr>

16904 2001-11-30 Akim Demaille <akim@epita.fr>
16906 * src/reduce.c (nonterminals_reduce): Instead of throwing away
16907 useless nonterminals, move them at the end of the symbol arrays.
16908 (reduce_output): Adjust.
16909 * tests/reduce.at (Useless Nonterminals): Adjust.
16911 2001-11-30 Akim Demaille <akim@epita.fr>

16920 * src/bison.simple (YYSTACK_REALLOC): Remove.
16921 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
16922 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
16924 (union yyalloc): New type.
16925 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
16926 an arbitrary restriction on hosts where size_t is wider than int.
16928 (yyparse): Don't dump core if alloca or malloc fails; instead, report
16929 a parser stack overflow. Allocate just one block of memory for all
16930 three stacks, instead of allocating three blocks; this typically is
16931 faster and reduces fragmentation.
16933 Do not limit the number of items in the stack to a value that fits
16934 in 'int', as this is an arbitrary limit on hosts with 64-bit
16935 size_t and 32-bit int.
16937 2001-11-29 Marc Autret <autret_m@epita.fr>
16939 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
16940 of defining YYERROR_VERBOSE.

16985 2001-11-28 Akim Demaille <akim@epita.fr>
16987 * src/closure.c (closure): `b' and `ruleno' denote the same value:
16990 2001-11-28 Akim Demaille <akim@epita.fr>
16992 * src/closure.c (closure): Instead of looping over word in array
16993 then bits in words, loop over bits in array.
16995 2001-11-28 Akim Demaille <akim@epita.fr>
16997 * src/closure.c (closure): No longer optimize the special case
16998 where all the bits of `ruleset[r]' are set to 0, to make the code
17001 2001-11-28 Akim Demaille <akim@epita.fr>
17003 * src/closure.c (closure): `r' and `c' are new variables, used to

17020 From Enrico Scholz.
17022 2001-11-27 Paul Eggert <eggert@twinsun.com>
17024 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

17367 use abs. path to find config.h.
17368 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

18740 * src/conflicts.c (conflict_report): Be sure not to append to res
18741 between two calls, which could happen if both first sprintf were

18744 2001-02-08 Akim Demaille <akim@epita.fr>
18746 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
18747 New, from fileutils 4.0.37.
18748 * configure.in: Require Autoconf 2.49c. I took some time before
18749 making this decision. This is the only way out for portability
18750 issues in Bison, it would mean way too much duplicate effort to
18751 import in Bison features implemented in 2.49c since 2.13.
18752 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
18754 2001-02-02 Akim Demaille <akim@epita.fr>

18771 * src/lex.h: Rename all the tokens:
18772 s/\bENDFILE\b/tok_eof/g;
18773 s/\bIDENTIFIER\b/tok_identifier/g;
18775 Let them be enums, not #define, to ease debugging.

18793 * src/reader.c (read_declarations): Adjust.
18794 * src/files.c (open_files): Don't call `compute_base_names', don't

18798 * src/output.c (output_headers): Document the fact that this patch
18799 introduces a guaranteed SEGV for semantic parsers.
18800 * doc/bison.texinfo: Document them.
18801 * tests/suite.at: Exercise these %options.
18803 2000-12-20 Akim Demaille <akim@epita.fr>

18826 2000-12-20 Akim Demaille <akim@epita.fr>
18828 * src/files.c (open_files): Actually the `.output' file is based

18868 (obstack_grow_string): this.
18869 * src/output.c (output_parser): Recognize `%% actions' instead of
18871 * src/bison.s1: s/$/%% actions/.
18872 * src/bison.hairy: Likewise.
18874 2000-12-19 Akim Demaille <akim@epita.fr>
18876 * src/output.c (output_parser): Compute the `#line' lines when

18901 2000-12-19 Akim Demaille <akim@epita.fr>
18903 * src/files.c (open_files): Yipee! We no longer need all the code

18908 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

18935 * lib/obstack.h: Formatting changes.
18936 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
18937 prevents type checking.
18938 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

18966 * acconfig.h: Remove, no longer used.
18968 2000-11-07 Akim Demaille <akim@epita.fr>
18970 * src: s/Copyright (C)/Copyright/g.
18972 2000-11-07 Akim Demaille <akim@epita.fr>
18974 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
18976 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

18986 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
18987 argument `data' for consistency with the prototypes.

18990 `address' for consistency. Qualify it `const'.
18991 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
18992 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
18993 `const' their input argument (`data' or `address').
18994 Adjust the corresponding macros to include `const' in casts.

18998 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

19006 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

19016 Don't use `atexit'.
19018 * src/files.c (obstack_save): New function.
19019 (done): Rename as...
19020 (output_files): this.
19021 Use `obstack_save'.
19022 * src/main.c (main): Don't use `atexit' to register `done', since
19023 it no longer has to remove tmp files, just call `output_files'
19024 when there are no errors.
19026 2000-11-02 Akim Demaille <akim@epita.fr>
19028 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
19029 `unlink': it's no longer used.
19030 * src/files.h: Formatting changes.
19032 2000-11-02 Akim Demaille <akim@epita.fr>
19034 Remove the last uses of mktemp and unlink/delete.
19036 * src/files.c (fdefines, ftable): Removed.
19037 (defines_ostack, table_obstack): New.
19038 Adjust dependencies of the former into uses of the latter.

19092 * src/reader.c (copy_dollar): Likewise.
19094 2000-10-16 Akim Demaille <akim@epita.fr>
19096 * src/reader.c (copy_comment2): Expect the input stream to be on
19097 the `/' which is suspected to open a comment, instead of being
19098 called after `//' or `/*' was read.
19099 (copy_comment, copy_definition, parse_union_decl, copy_action)
19100 (copy_guard): Adjust.
19102 2000-10-16 Akim Demaille <akim@epita.fr>
19104 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

19110 (copy_guard, copy_action): Use it.
19112 2000-10-16 Akim Demaille <akim@epita.fr>
19114 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
19115 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
19116 New files, from Fileutils 4.0.27.
19117 * src/main.c (printable_version): Remove.
19118 * src/lex.c, src/reader.c: Use `quote'.
19120 2000-10-04 Akim Demaille <akim@epita.fr>
19122 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
19124 2000-10-04 Akim Demaille <akim@epita.fr>
19126 * doc/bison.texinfo: Various typos spotted by Neil Booth.
19128 2000-10-04 Akim Demaille <akim@epita.fr>
19130 When a literal string is used to define two different tokens,
19131 `bison -v' segfaults.
19132 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
19134 * tests/regression.m4: New file.
19135 Include the core of the sample provided by Piotr Gackiewicz.
19136 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
19139 2000-10-04 Akim Demaille <akim@epita.fr>

19151 2000-10-02 Akim Demaille <akim@epita.fr>
19153 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19156 2000-10-02 Akim Demaille <akim@epita.fr>
19158 * src/derives.c, src/print.c, src/reduce.c: To ease the
19159 translation, move some `\n' out of the translated strings.
19161 2000-10-02 Akim Demaille <akim@epita.fr>
19163 The location tracking mechanism is precious for parse error
19164 messages. Nevertheless, it is enabled only when `@n' is used in
19165 the grammar, which is a different issue (you can use it in error
19166 message, but not in the grammar per se). Therefore, there should
19167 be another means to enable it.
19169 * src/getargs.c (getargs): Support `--locations'.
19170 (usage): Report it.
19171 * src/getargs.h (locationsflag): Export it.

19173 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19174 with `locationsflag'.
19175 * doc/bison.texinfo: Document `--locations' and `%locations'.
19177 * tests/calc.m4: Test it.
19179 For regularity of the names, replace each
19180 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
19181 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
19182 In addition replace each `flag' with `_flag'.
19184 2000-10-02 Akim Demaille <akim@epita.fr>
19186 Also test parse error messages, including with YYERROR_VERBOSE.
19188 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
19190 Use it to check the computations.
19191 Use it to check `nonassoc' is honored.
19192 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
19193 `--yyerror-verbose'.
19194 (_AT_CHECK_CALC): Adjust to this option.
19195 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
19197 2000-10-02 Akim Demaille <akim@epita.fr>
19199 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19200 the latter demonstrates a flaw in the handling of non debugging
19201 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19202 was used in order to simplify:
19218 unfortunately this leads to a CPP conflict when
19219 `--name-prefix=foo' is used since it produces `#define yydebug
19222 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
19223 (YYDPRINTF): New macro.
19225 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
19227 Also test `--verbose', `--defines' and `--name-prefix'.
19229 2000-10-02 Akim Demaille <akim@epita.fr>
19231 Improve the readability of the produced parsers.
19233 * src/bison.s1: Formatting changes.
19234 Improve the comment related to the `$' mark.
19235 (yydefault): Don't fall through to `yyresume': `goto' there.
19236 * src/output.c (output_parser): When the `$' is met, skip the end
19238 New variable, `number_of_dollar_signs', to check there's exactly
19239 one `$' in the parser skeleton.
19241 2000-10-02 Akim Demaille <akim@epita.fr>
19243 * lib/xstrdup.c: New file, from the fileutils.
19244 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
19245 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
19246 instead of strlen + xmalloc + strcpy.
19247 * src/symtab.c (copys): Remove, use xstrdup instead.
19249 2000-10-02 Akim Demaille <akim@epita.fr>
19251 * src/gram.h (associativity): New enum type which replaces the
19252 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
19253 `right_assoc', `left_assoc' and `non_assoc'.
19254 Adjust all dependencies.
19255 * src/reader.c: Formatting changes.
19256 (LTYPESTR): Don't define it, use it as a literal in
19257 `reader_output_yylsp'.
19258 * src/symtab.h (symbol_class): New enum type which replaces the
19259 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
19260 `sunknown', `stoken and `snterm'.
19262 2000-10-02 Akim Demaille <akim@epita.fr>
19264 * src/getargs.c (fixed_outfiles): Rename as...
19265 (yaccflag): for consistency and accuracy.
19266 Adjust dependencies.
19268 2000-10-02 Akim Demaille <akim@epita.fr>
19270 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19271 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19272 difficult and introduced a lot of core dump. It turns out that
19273 Bison used an implementation of `xmalloc' based on `calloc', and
19274 at various places it does depend upon the initialization to 0. I
19275 have not tried to isolate the pertinent places, and all the former
19276 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19277 someone should address this issue.
19279 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
19280 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

19286 2000-10-02 Akim Demaille <akim@epita.fr>
19288 Various anti-`extern in *.c' changes.
19290 * src/system.h: Include `assert.h'.
19292 2000-10-02 Akim Demaille <akim@epita.fr>
19294 * src/state.h (nstates, final_state, first_state, first_shift)
19295 (first_reduction): Move their exportation from here...
19296 * src/LR0.h: to here.
19297 Adjust dependencies.
19298 * src/getargs.c (statisticsflag): New variable.
19299 Add support for `--statistics'.
19300 Adjust dependencies.
19302 Remove a lot of now useless `extern' statements in most files.
19304 2000-10-02 Akim Demaille <akim@epita.fr>
19306 * src/LR0.h: New file.
19309 2000-10-02 Akim Demaille <akim@epita.fr>

19335 * src/reduce.h: New file.
19336 Propagate its inclusion.
19337 * src/reduce.c: Topological sort and other formatting changes.
19338 (bool, TRUE, FALSE): Move their definition to...
19339 * src/system.h: here.
19341 2000-10-02 Akim Demaille <akim@epita.fr>
19343 * src/files.c: Formatting changes.
19344 (tryopen, tryclose, openfiles): Rename as...
19345 (xfopen, xfclose, open_files): this.
19346 (stringappend): static.

19370 * src/lalr.c: Formatting changes, topological sorting etc.
19372 2000-10-02 Akim Demaille <akim@epita.fr>
19374 * src/output.c (token_actions): Introduce a temporary array,
19375 YYDEFACT, that makes it possible for this function to use
19376 output_short_table.
19378 2000-10-02 Akim Demaille <akim@epita.fr>
19380 `user_toknums' is output as a `short[]' in `output.c', while it is
19381 defined as a `int[]' in `reader.c'. For consistency with the
19382 other output tables, `user_toknums' is now defined as a table of
19385 * src/reader.c (user_toknums): Be a short table instead of an int

19425 Don't define PARAMS.
19426 * src/system.h: Define PARAMS.
19427 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
19428 purpose of config.h. system.h must not try to fix wrong
19429 definitions in config.h.

19558 * src/main.c (main): Register `done' to `atexit'.

19626 (copy_comment): Likewise.
19628 2000-03-17 Akim Demaille <akim@epita.fr>
19630 * src/reader.c (packsymbols): Formatting changes.

19645 2000-03-17 Akim Demaille <akim@epita.fr>
19647 Change the handling of @s so that they behave exactly like $s.
19648 There is now a pseudo variable @$ (readble and writable), location
19649 of the lhs of the rule (by default ranging from the location of
19650 the first symbol of the rhs, to the location of the last symbol,
19651 or, if the rhs is empty, YYLLOC).
19653 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
19655 (yyparse): When providing a default semantic action, provide a
19656 default location action.
19657 (after the $): No longer change `*YYLSP', just stack YYLOC the
19658 same way you stack YYVAL.
19659 * src/reader.c (read_declarations): Use warns.
19660 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
19661 (copy_action, case '@'): Likewise.
19662 Use a standard error message, to save useless work from

19685 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
19686 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
19687 One `#if YYDEBUG' remains, since it uses variables which are
19688 defined only if `YYDEBUG != 0'.
19690 2000-03-16 Akim Demaille <akim@epita.fr>
19692 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

19706 Update the `configure' tool chain.
19708 * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
19710 (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
19711 (AC_OUTPUT): Add m4/Makefile.
19712 Bump to bison 1.28a, 1.29 has never been released.

20345 1995-10-15 Richard Stallman <rms@gnu.org>
20347 * src/vmsgetargs.c, src/getargs.c:
20348 Added -n, -k, and -raw switches.

20356 Revise error message.
20357 (print_notices): Remove final `.' from error message.
20359 * src/reader.c (reader_output_yylsp):
20361 (readgram): Use `#if 0' around code that accepted %command
20362 inside grammar rules: The documentation doesn't allow it,
20363 and it will fail since the %command processors scan for the next %.
20364 (parse_token_decl): Extended the %token
20365 declaration to allow a multi-character symbol as an alias.
20366 (parse_thong_decl): New function.
20367 (read_declarations): Added %thong declarations.
20368 (read_declarations): Handle NOOP to deal with allowing
20369 % declarations as another means to specify the flags.
20370 (readgram): Allow %prec prior to semantics embedded in a rule.
20371 (skip_to_char, read_declarations, copy_definition)
20372 (parse_token_decl, parse_start_decl, parse_type_decl)
20373 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
20374 (get_type_name, copy_guard, copy_action, readgram)
20375 (get_type, packsymbols): Revised most error messages.
20376 Changed `fatal' to `warnxxx' to avoid aborting for error.
20377 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20378 (read_declarations): Improve the error message for
20379 an invalid character. Do not abort.
20380 (read_declarations, copy_guard, copy_action): Use
20381 printable_version to avoid unprintable characters in printed output.
20382 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
20383 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
20384 Allow the type of a non-terminal can be given
20385 more than once, as long as all specifications give the same type.
20388 (output_headers, output_trailers, output, output_gram)
20389 (output_rule_data): Implement noparserflag variable.
20390 Implement toknumflag variable.
20391 (output): Call reader_output_yylsp to output LTYPESTR.
20393 * src/main.c (main):
20394 If reader sees an error, don't process the grammar.
20395 (fatals): Updated to not use VARARGS1.
20396 (printable_version, int_to_string, warn, warni, warns, warnss)
20397 (warnsss): New error reporting functions. Avoid abort for error.
20400 Added THONG and NOOP for alias processing.
20401 Added SETOPT for the new code that allows setting options with %flags.
20404 Include getopt.h. Add some extern decls.
20405 (safegetc): New function to deal with EOF gracefully.
20406 (literalchar); new function to deal with reading \ escapes.
20407 (lex): Use literalchar.
20408 (lex): Implemented "..." tokens.
20409 (literalchar, lex, parse_percent_token): Made tokenbuffer
20410 always contain the token. This includes growing the token
20411 buffer while reading an integer.
20412 (parse_percent_token): Replaced if-else statement with percent_table.
20413 (parse_percent_token): Added % declarations as another
20414 way to specify the flags -n, -l, and -r. Also added hooks for
20415 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
20416 major changes to files.c.
20417 (lex) Retain in the incoming stream a character following
20419 (skip_white_space, lex): Revised most error messages
20420 and changed fatal to warn to avoid aborting.
20421 (percent_table): Added %thong declarations.
20423 * src/gram.h: Comment changes.
20425 * src/files.c (openfiles, open_extra_files, done):
20427 and actfile file. Handle noparserflag. Both for -n switch.
20429 * src/conflicts.c (resolve_sr_conflict):
20430 Remove use of alloca.
