60 nodist_PROGRAMS, since we don't need to actually compile the

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

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

408 (Special Features for Use in Actions): Add YYEOF entry and mention it
410 In the yychar entry, remove mention of the local yychar case (pure
411 parser) since this is irrelevant information when writing semantic
412 actions and since it's already discussed in `Bison Symbols' where
413 yychar is otherwise described as an external variable.
414 In the yychar entry, don't call it the `current' look-ahead since it
415 isn't when semantic actions are deferred.

435 actually needed the current lookahead.

437 Allocate, deallocate, resize, and otherwise shuffle space for
438 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.

440 appropriately during nondeterministic operation.
441 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
442 members to store the current lookahead to be used by the deferred
444 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
445 from which the RHS is taken. Set the lookahead members of the new
446 yySemanticOption according to the lookahead status for stack yyk.

465 !yyvaluep as signal that no semantic value is available to print.

467 to print a semantic value.

474 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
476 * data/glr.c (yyresolveValue): When merging semantic options, if at
477 least one user action succeeds but a later one cuts the parse, then
478 destroy the semantic value before returning rather than leaking it.
479 (yyresolveStates): If a user action cuts the parse and thus
480 yyresolveValue fails, ignore the (unset) semantic value rather than
481 corrupting the yyGLRState, and empty the semantic options list since

784 sed out the final state number.
786 Work around portability problem on Solaris 10: flex-generated
787 files include <stdio.h> before <config.h>, which messes up
788 because the latter defines __EXTENSIONS__. Address the problem
789 by creating two new little files that include <config.h> first,

872 * data/lalr1.cc: Likewise.

1077 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at

1131 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
1133 Undo the parts of the unlocked-I/O change that substituted
1134 putc or puts for printf. This might hurt performance a bit,
1135 but some people prefer the printf style.
1136 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
1137 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

1158 unused-variable warnings.
1160 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

1164 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
1166 Use unlocked I/O for a minor performance improvement on hosts like
1167 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1168 is to use the gnlib unlocked-io module, and to prefer putc and
1169 puts to printf when either will work (since the latter doesn't
1170 come in an unlocked flavor).
1171 * bootstrap (gnulib_modules): Add unlocked-io.

1190 * src/system.h: Include unlocked-io.h rather than stdio.h.
1192 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

1242 to allow support for non-posix systems. This is a no-op function
1245 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
1246 handle the lack of pipe/fork functionality on non-posix systems.

1286 indirection to YYSTYPE.

1330 local variables whose names begin with 'yy'.
1331 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1332 Trivial changes from Joel E. Denny.
1334 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1336 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1337 don't use alloca any more.
1339 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1340 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&

1352 This works a bit better with glibc, if user code has already included
1354 * doc/bison.texinfo (Bison Parser): Document that users can't
1355 arbitrarily use malloc and free for other purposes. Document

1374 Instead, reallocate buffers twice as big each time, so that
1375 we waste at most half the allocated memory. Start with a small
1376 (128-byte) buffer that will suffice in most cases anyway.
1377 Use yysyntax_error to do most of the work.
1379 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1380 yynerrs is the number of errors reported, not the number of

1387 Don't start user-code symbols with "yy", to avoid name space problems.
1389 2005-09-19 Akim Demaille <akim@epita.fr>
1391 Remove the traits, failed experiment.
1392 It never proved useful, and anyway because of the current
1393 definition, it was not possible to have several specialization of
1394 this traits, making it useless.
1395 * data/lalr1.cc (yy:traits): Remove.
1396 Inline its definitions in the parser class.
1398 2005-09-19 Akim Demaille <akim@epita.fr>

1423 is not defined. This is an awful hack, but it's enough for now.
1424 All callers changed.
1425 * tests/glr-regression-at (make_value): Args are const pointers now,
1426 to avoid GCC warning.
1427 (Duplicated user destructor for lookahead): New test. Currently
1428 skipped. It fails on my host but I'm not sure it'll always fail.

1473 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
1474 (b4_filename_type): Renamed back from b4_file_name_type. All uses
1476 (class position): file_name -> filename (reverting). All uses changed.
1478 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
1480 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1481 do anything if $@ exists. This reverts part of the 2005-07-07
1484 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1486 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1487 contains obsolete information and isn't worth distributing as a
1488 separate file anyway.
1489 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1490 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
1491 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
1492 (yyparse): Abort if user code uses longjmp to throw an unexpected
1495 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
1497 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1498 Suggested by twlevo@xs4all.nl.
1500 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1501 This avoids a diagnostic from gcc -Wswitch-enum.
1502 Problem reported by twlevo@xs4all.nl.
1504 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1505 standards. Use "file name" or "file" or "name", depending on
1507 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1508 not to hack/foo.tab.c.
1509 (Calc++ Top Level): 2nd arg of main is not const.
1510 * data/glr.c: b4_filename -> b4_file_name.
1511 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
1513 (class position): filename -> file_name. All uses changed.

1515 * lib/bitset.h: filename -> file_name in local vars.
1516 * lib/bitset_stats.c: Likewise.
1517 * src/files.c: Likewise.

1519 * src/files.c (file_name_split): Renamed from filename_split.
1520 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
1522 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
1524 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
1525 to accommodate latest gnulib.
1527 * tests/glr-regression.at (Duplicate representation of merged trees):
1528 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
1530 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
1533 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1535 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
1536 All uses changed. Invoke user destructor after an error during a
1537 split parse (trivial change from Joel E. Denny).
1539 * tests/glr-regression.at
1540 (User destructor after an error during a split parse): New test case.
1541 Problem reported by Joel E. Denny in:
1542 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
1544 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1546 * README-cvs: Give URLs for recommended tools.
1547 Mention Gzip version problem, and bootstrapping issues.
1548 Remove troubleshooting section, as it's somewhat obsolete.
1550 * bootstrap (no_cache): New var, to accommodate different wget
1551 variants. Use it instead of '-C off'. Problem reported by
1554 * data/glr.c (yydestroyStackItem): New function.
1555 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
1556 debugging information. Problem reported by Joel E. Denny.
1558 2005-08-25 Akim Demaille <akim@epita.fr>
1560 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
1562 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
1564 * data/glr.c (yyrecoverSyntaxError, yyreturn):
1565 Don't invoke destructor on unresolved entries.
1566 * tests/glr-regression.at
1567 (User destructor for unresolved GLR semantic value): New test case.
1568 Problem reported by Joel E. Denny in:
1569 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
1571 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
1573 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
1575 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
1576 lib-prefix.m4, po.m4.
1578 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
1579 in yydestruct diagnostic, since it might not be an error.
1580 Problem reported by Joel Denny near end of
1581 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1582 * data/lalr1.cc (yyerturn): Likewise.
1583 * data/yacc.c (yyreturn): Likewise.
1584 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
1586 * src/files.c: Remove obsolete FIXME comment.
1588 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1589 with the other templates, and to fix bogus run-on messages such
1590 as the one reported at the end of
1591 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1592 All callers changed to avoid the newline.
1593 (yyprocessOneStack): Output two lines rather than one, to accommodate
1594 the above change. This changes the debug output format slightly.
1596 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1597 reported by Joel E. Denny in
1598 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1600 * tests/glr-regression.at (Duplicate representation of merged trees):
1601 New test, from Joel E. Denny in:
1602 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
1603 * THANKS: Add Joel E. Denny.
1605 * configure.ac (AC_INIT): Bump to 2.0c.
1607 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1609 * NEWS: Version 2.0b.
1611 * Makefile.am (SUBDIRS): Put examples before tests, so that
1612 "make check" doesn't finish with "All 1 tests passed".
1614 * tests/regression.at (Token definitions): Don't rely on
1615 AT_PARSER_CHECK for data that contains backslashes. It currently
1616 uses 'echo', and 'echo' isn't portable if its argument contains
1617 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1618 that the byte '\0xff' is not printable in the C locale; it is,
1619 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1620 not printable, so use '\0x81' to test.
1622 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1623 version of GCC, since the macro is used with non-GCC compilers.
1625 Fix core dump reported by Pablo De Napoli in
1626 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1627 * tests/regression.at (Invalid inputs with {}): New test.
1628 * src/parse-gram.y (token_name): Translate type before using
1631 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1632 the user's name space. All uses changed to __attribute__
1634 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1635 Add __attribute__ ((__noreturn__)).
1637 * etc/clcommit: Remove. We weren't using it, and it failed
1638 "make maintainer-distcheck".
1639 * Makefile.maint: Merge from coreutils.
1640 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1641 (syntax-check-rules): Change list of rules as described below.
1642 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
1643 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
1644 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
1645 (sc_trailing_space): New rules.

1648 (sc_space_tab, sc_error_exit_success, sc_changelog):
1649 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
1650 (makefile-check, po-check, author_mark_check):
1651 (makefile_path_separator_check, copyright-check):
1652 Use grep -n, to make it easier to find violations.
1653 Use CVS_LIST and CVS_LIST_EXCEPT.
1654 (header_regexp, h_re): Remove.
1656 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1657 (my-distcheck): Use more-modern GCC flags.
1658 (signatures, %.asc): Remove.
1659 (rel-files, announcement): Remove signatures.
1660 Restore old updating code, even though we don't use it, so
1661 that we're the same as coreutils.
1662 (alpha, beta, major): Depend on news-date-check.
1663 Make the upload commands.
1665 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
1666 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
1667 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
1668 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

1672 * tests/sets.at: Likewise.
1674 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1675 we comment out the Autoconf version number.
1676 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1677 it's error-prone and "make maintainer-distcheck" rejects it.
1679 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1680 Indent calls to "error" to pacify "make maintainer-distcheck",
1681 when the calls are not intended to be translated.
1682 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1684 * src/Makefile.am (DEFS): Use +=, to pacify
1685 "make maintainer-distcheck".
1686 (bison_SOURCES): Add scan-skel.h.
1687 (sc_tight_scope): New rule, from coreutils.
1689 * src/files.c (src_extension, header_extension):
1690 Now static, not extern.
1691 * src/getargs.c (short_options): Likewise.
1692 * src/muscle_tab.c (muscle_table): Likewise.
1693 * src/parse-gram.y (current_class, current_type, current_prec):
1695 * src/reader.c (grammar_end, previous_rule_end): Likewise.
1696 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
1697 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1698 void, to avoid warning when NLS is disabled.
1699 * src/output.c: Include scan-skel.h.
1700 (scan_skel): Remove decl, since scan-skel.h does this.
1702 Indent calls to "error" to pacify "make maintainer-distcheck".
1703 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1704 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1705 "make maintainer-distcheck".
1706 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1707 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1708 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
1709 (skel_lex_destroy, scan_skel): Move these decls to...
1710 * src/scan-skel.h: New file.
1711 * src/uniqstr.c (uniqstr_assert):
1712 Indent calls to "error" to pacify "make maintainer-distcheck".
1714 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1717 * tests/torture.at: Revamp to avoid misuse of atoi that
1718 "make maintainer-distcheck" complained about.
1720 * examples/extexi (message): Don't print a message more than once,
1721 and omit line-number decoration that makes Emacs compile think
1722 that informative messages are worth worrying about.
1724 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
1726 * configure.ac: Update version number.
1728 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1730 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1731 autogenerated by the maintainer.
1732 * examples/calc++/.cvsignore: Add *.yy.
1734 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
1735 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1736 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1738 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1740 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1741 from maintainer-distcheck about casting the argument of 'free'.
1743 * NEWS: Mention recent yytname changes.
1744 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1746 * bootstrap: For translations that have not yet been upgraded to
1747 the new runtime-po domain, prime the pump by extracting the
1748 relevant strings from the obsolete translations. This code can be
1749 removed once the bison-runtime domain has been translated by each
1752 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1753 now that token names are already quoted.
1755 Fix problem reported by Anthony Heading.
1756 * data/glr.c (YYTOKEN_TABLE): New macro.
1757 (yytname): Define if YYTOKEN_TABLE.
1758 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
1759 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
1760 (YYERROR_VERBOSE): Define the same way the other skeletons do.
1761 * src/output.c (prepare_symbols): Output token_table_flag.
1763 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
1765 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
1766 again if the first call fails.
1768 * data/glr.c (yytnamerr): New function.
1769 (yyreportSyntaxError): Use it to dequote most string literals.
1770 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1771 with other skeletons. All uses changed.
1772 (yytnameerr_): New function.
1773 (yyreport_syntax_error): Use it to dequote most string literals.
1774 * data/yacc.c (yytnamerr): New function.
1775 (yyerrlab): Use it to decode most string literals.
1776 * doc/bison.texinfo (Decl Summary, Calling Convention):
1777 Clarify quoting convention of yytname.
1778 * src/output.c (prepare_symbols): Quote all names. This undoes
1779 the 2005-04-17 change, which is now accomplished (mostly) via
1780 changes in the parsers as described above.
1781 * tests/regression.at (Token definitions, Web2c Actions):
1782 Undo most 2005-04-17 change here, too.
1784 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
1786 Fix more problems reported by twlevo@xs4all.nl.
1787 * tests/cxx-type.at: Don't pipe output of ./types through sed to
1788 remove trailing spaces. This loses the exit status of ./types,
1789 and isn't needed since ./types shouldn't be emitting trailing
1791 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
1792 as the stack isn't valid in that case.
1794 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
1795 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
1796 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
1797 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
1799 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
1800 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
1801 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
1804 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
1805 overly-picky compilers that reject 'char *foo = "bar";'.
1807 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
1808 to FILE * parameter, not to stderr. This fixes a typo introduced
1809 in the 2005-07-12 change.
1811 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
1812 warnings from GCC 4.
1814 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
1815 (yyglrShiftDefer, yysplitStack):
1816 Remove unused parameters b4_pure_formals. All uses changed.
1817 (yyglrShift): Remove unused parameters b4_user_formals.
1819 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
1821 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
1823 Destructor cleanups and regularization among the three skeletons.
1824 * NEWS: Document the behavior changes.
1825 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
1826 stack before failing, as the cleanup code will do it for us now.
1827 * data/lalr1.cc (yyerrlab): Likewise.
1828 * data/glr.c (yyparse): Pop everything off the stack before
1829 freeing it, so that destructors get called properly.
1830 * data/lalr1.cc (yyreturn): Likewise.
1831 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
1832 This is more consistent.
1833 * doc/bison.texinfo (Destructor Decl): Mention more reasons
1834 why destructors might be called. 1.875 -> 2.1.
1835 (Destructor Decl, Decl Summary, Table of Symbols):
1836 Some English-language cleanups for %destructor.
1837 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1838 Add output line for destructor of start symbol.
1839 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
1840 because of that same extra output line.
1842 * NEWS: Document minor wording changes in diagnostics of
1843 Bison-generated parsers.
1844 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
1845 Remove unused formals. All uses changed.
1846 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
1847 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
1848 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
1849 Rename yyoverflowab to yyexhaustedlab.
1850 When memory exhaustion occurs during syntax-error reporting,
1851 report it separately rather than in a single diagnostic; this
1853 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
1854 (Memory Exhausted): Renamed from Parser Stack Overflow.
1855 Revamp wording slightly to prefer "memory exhaustion".
1856 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
1858 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
1860 Add i18n support to the GLR skeleton. Partially fix the C++
1861 skeleton; a C++ expert needs to finish this. Remove debugging
1862 msgids; there's little point to having them translated, since they
1863 can be understood only by someone who can read the
1864 (English-language) source code.
1866 Generate runtime-po/bison-runtime.pot automatically, so that we
1867 don't have to worry about garbage getting in that file. We'll
1868 make sure after the next official release that old msgids don't
1870 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
1872 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
1874 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
1875 Fix typos in explanations of the runtime file.
1876 * bootstrap: Change gettext keyword from YYI18N to YY_.
1877 Use standard Makefile.in.in in runtime-po, since we'll arrange
1878 for backward-compatible bison-runtime.po files in a different way.
1879 * data/glr.c (YY_): New macro, from yacc.c.
1880 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
1881 Translate messages intended for users.
1882 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
1883 the wording in the other skeletons. We don't know that the memory
1885 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
1886 Use same method that yacc.c uses.
1887 Don't translate debugging messages.
1888 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
1889 it doesn't work (yet), and requires C++ expertise to fix.
1890 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
1891 Move defn to a more logical place, to be consistent with other
1893 Don't translate debugging messages.
1894 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
1895 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
1896 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
1897 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
1899 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
1900 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
1902 * tests/glr-regression.at (Badly Collapsed GLR States):
1904 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1905 yylex should return 0 at EOF rather than aborting.
1907 Improve tests for stack overflow in GLR parser.
1908 Problem reported by twlevo@xs4all.nl.
1909 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
1911 (yyStackOverflow): Just longjmp, but with value 2 so that caller
1912 can handle the problem.
1913 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
1914 (yyparse): New local variable yyresult to record the result.
1915 Use result of setjmp to set it, rather than storing itinto
1917 (yyDone): Remove label.
1918 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
1919 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
1920 if YYABORT is used).
1921 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
1922 yyparse status; put status > 1 into diagnostic.
1923 Check that status==2 works.
1924 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
1925 Use exit status 3 for failure to open (which shouldn't happen).
1927 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
1929 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
1930 1 on syntax error; just let yyparse do its thing.
1931 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
1932 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
1933 (Exploding the Stack Size with Alloca):
1934 (Exploding the Stack Size with Malloc):
1935 Expect exit status 2, not 1, since the parser is supposed to blow
1936 its stack. Problem reported by twlevo@xs4all.nl.
1938 * data/glr.c (yyparse): Don't assume that the initial calls
1939 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
1940 Print a stack-overflow message and fail instead.
1941 Initialize the line-number information before creating the stack,
1942 so that the stack-overflow message can report line zero safely.
1944 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
1946 Fix problems reported by twlevo@xs4all.nl.
1947 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
1948 (yyuserMerge): Provide a default case if b4_mergers is empty.
1949 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
1950 * tests/glr-regression.at
1951 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1952 Add casts to pacify C++ compilers.
1953 * tests/glr-regression.at (Improper merging of GLR delayed action
1954 sets): Declare yylex before using it.
1955 * tests/Makefile.am (maintainer-check-g++): Fix a stray
1956 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
1957 test for valgrind; valgrind is independent of g++.
1958 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
1959 for compatibility with POSIX 1003.1-2001 (if running coreutils).
1960 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
1961 Use a destructor, so that we can expand the stack. Change
1962 YYSTYPE to char * so that we can free it. Cast result of malloc.
1964 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
1966 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
1967 a valgrind failure. Problem reported by twlevo@xs4all.nl.
1969 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
1971 * PACKAGING: New file, suggested by Bruno Haible and taken from
1972 similar wording in gettext's PACKAGING file.
1973 * NEWS: Mention PACKAGING.
1974 * Makefile.am (EXTRA_DIST): Add PACKAGING.
1976 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
1978 * NEWS: Document recent i18n improvements.
1979 * bootstrap: Get runtime translations into runtime-po.
1980 Create runtime-po files automatically, if possible.
1981 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
1982 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
1983 does not infringe on the user's name space.
1984 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
1985 * doc/bison.texinfo (Internationalization): Revamp the English
1986 and Texinfo syntax a bit, to try to make it clearer.
1987 (Bison Options, Option Cross Key): Mention --print-localedir.
1988 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
1989 YYENABLE_NLS. Quote a bit more.
1990 * runtime-po/.cvsignore: New file.
1991 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
1992 * runtime-po/Rules-quot: Remove; now created by bootstrap.
1993 * runtime-po/quot.sed: Likewise.
1994 * runtime-po/boldquot.sed: Likewise.
1995 * runtime-po/en@quot.header: Likewise.
1996 * runtime-po/en@boldquot.header: Likewise.
1997 * runtime-po/insert-header.sin: Likewise.
1998 * runtime-po/remove-potcdate.sin: Likewise.
1999 * runtime-po/Makevars: Likewise.
2000 * runtime-po/LINGUAS: Likewise.
2001 * runtime-po/de.po: Likewise; we will rely on the translation project
2002 to maintain this, so "bootstrap" should get it.
2003 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2005 * src/main.c (main): Bind the bison-runtime domain, too.
2007 2005-07-12 Bruno Haible <bruno@clisp.org>
2009 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2010 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2011 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2012 * runtime-po: New directory.
2013 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2014 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2015 * runtime-po/Rules-quot: New file, copied from po/.
2016 * runtime-po/quot.sed: Likewise.
2017 * runtime-po/boldquot.sed: Likewise.
2018 * runtime-po/en@quot.header: Likewise.
2019 * runtime-po/en@boldquot.header: Likewise.
2020 * runtime-po/insert-header.sin: Likewise.
2021 * runtime-po/remove-potcdate.sin: Likewise.
2022 * runtime-po/Makevars: New file.
2023 * runtime-po/POTFILES.in: New file.
2024 * runtime-po/LINGUAS: New file.
2025 * runtime-po/bison-runtime.pot: New file.
2026 * runtime-po/de.po: New file.
2027 * m4/bison.m4: New file.
2028 * Makefile.am (SUBDIRS): Add runtime-po.
2029 (aclocaldir, aclocal_DATA): New variables.
2030 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2032 * src/getargs.c (usage): Document --print-localedir option.
2033 (PRINT_LOCALEDIR_OPTION): New enum item.
2034 (long_options): Add --print-localedir option.
2035 (getargs): Handle --print-localedir option.
2036 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2037 (Internationalization): New section.
2039 2005-07-12 Akim Demaille <akim@epita.fr>
2041 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2042 for consistency with the rest of the code.
2043 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2046 2005-07-12 Akim Demaille <akim@epita.fr>
2048 * src/parse-gram.y: Use %printer instead of YYPRINT.
2050 2005-07-12 Akim Demaille <akim@epita.fr>
2052 * src/symtab.h, src/symtab.c (symbol_print): New.
2053 * src/symlist.h, src/symlist.c (symbol_list_print): New.

2056 2005-07-12 Akim Demaille <akim@epita.fr>
2058 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2059 b4_at_dollar and b4_dollar_dollar.
2061 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2063 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2064 and Pennello's paper.
2066 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2068 * data/yacc.c (yyparse): Undo previous patch. Instead,
2069 set yylsp[0] and yyvsp[0] only if the initial action
2070 sets yylloc and yylval, respectively.
2072 * data/yacc.c (yyparse): In the initial action, set
2073 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2074 This avoids the use of undefined variables if the initial
2075 action does not set yylloc and/or yylval.
2077 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2079 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2080 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2081 Remove from CVS. These files are automatically generated.
2082 * examples/extexi: Clarify that this file is now part of Bison,
2083 not GNU M4, and that it works with any POSIX-compatible Awk.
2084 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2085 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2086 so that we also get calc++-parser.yy. Geneate it.
2087 Use $(AWK), not gawk, since any conforming Awk will do.
2088 Put comment before action, since older 'make' can't handle comment
2090 $(BUILT_SOURCES): List all built sources, not just some of them.
2091 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2092 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2093 $($(calc_sources_generated)): Remove unnecessary test for existence
2094 of target. (This had a shell syntax error anyway; a stray "x".)
2095 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2097 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2099 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2100 implied by the other modules.
2102 2005-07-06 Akim Demaille <akim@epita.fr>
2104 Bind examples/calc++ to the package.
2105 * examples/calc++/Makefile: Remove, replaced by...

2107 * examples/calc++/test: Remove input.
2108 * examples/calc++/compile: Remove.
2109 * examples/Makefile.am: New.
2110 * configure.ac, Makefile.am: Adjust.
2111 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2113 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2115 * data/glr.c (yyFail): Drastically simplify; since the format argument
2116 never had any % directives, we can simply pass it to yyerror.
2117 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2118 be modified later, as that is the usual style in glr.c.
2119 Problems reported by Paul Hilfinger.
2121 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2122 and size overflow errors.
2123 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2124 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2125 (YYSIZEMAX): New macro.
2126 (yystpcpy): New function, taken from yacc.c.
2127 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2128 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2129 so that we don't have to maintain their signatures.
2130 (yyFail): Check for buffer overflow, by using vsnprintf rather
2131 than vsprintf. Allocate a bigger buffer if possible.
2132 Report an error if buffer allocation fails.
2133 (yyStackOverflow): New function.
2134 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2135 the initialization was successful. It might fail if storage was
2137 (yyexpandGLRStack): Add more checks for storage allocation failure.
2138 Use yyStackOverflow to report failures.
2139 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2140 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2141 Don't assume stack number fits in int.
2142 (yysplitStack): Check for storage allocation failure.
2143 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2144 can print diagnostics on storage allocation failure. All callers
2146 (yyresolveValue): Use yybool for boolean.
2147 (yyreportSyntaxError): Check for size-calculation overflow.
2148 This code is taken from yacc.c.
2149 (yyparse): Check for storage allocation errors when allocating
2152 2005-07-05 Akim Demaille <akim@epita.fr>
2154 Extract calc++ from the documentation.
2155 * doc/bison.texinfo (Calc++): Add the extraction marks.
2156 * examples/extexi: New, from the aborted GNU Programming 2E.
2157 Separate the different paragraph of a file with empty lines.
2158 * examples/Makefile: Use it to extract the whole calc++ example.
2160 2005-06-24 Akim Demaille <akim@epita.fr>
2162 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
2165 2005-06-22 Akim Demaille <akim@epita.fr>
2167 * doc/bison.texinfo (C++ Language Interface): First stab.
2168 (C++ Parsers): Remove.
2170 2005-06-22 Akim Demaille <akim@epita.fr>
2172 * data/lalr1.cc (yylex_): Honor %lex-param.
2174 2005-06-22 Akim Demaille <akim@epita.fr>
2176 Start a set of simple examples.
2177 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
2178 * examples/calc++/calc++-driver.hh,
2179 * examples/calc++/calc++-parser.yy,
2180 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
2181 * examples/calc++/compile, examples/calc++/test: New.
2183 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
2185 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2186 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2187 which stems from the 2005-05-27 patch.
2189 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2191 * data/glr.c: Modify treatment of unused parameters to permit use
2192 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2194 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2196 Fix infringement on user name space reported by Janos Zoltan Szabo.
2197 * data/yacc.c (yyparse): strlen -> yystrlen.
2199 2005-05-30 Akim Demaille <akim@epita.fr>
2201 * data/lalr1.cc (_): New.
2202 Translate the various messages.
2204 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2206 Fix infringement on user name space reported by Bruno Haible.
2207 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2208 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2209 the user's name space.
2210 (alloca): Include <stdlib.h> to get it, if it's not built in.
2211 (YYMALLOC, YYFREE): Define only if needed.
2212 (malloc, free): Declare, but only if needed, as this infringes on
2213 the user name space.
2215 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2217 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
2218 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
2220 * lib/ebitset.c (min, max): Undef before defining.
2221 * lib/vbitset.c (min, max): Likewise.
2222 * lib/subpipe.c (create_subpipe): Save local variables in case
2223 vfork clobbers them.
2225 2005-05-24 Bruno Haible <bruno@clisp.org>
2227 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2228 error message syntax used by gcc-4.0.
2230 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2232 * README: Mention m4 1.4.3. Remove obsolete advice about
2233 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2235 * bootstrap: Remove workaround for problem I encountered with
2236 gettext 0.14.1; it seems to be fixed now.
2238 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2240 * NEWS: Version 2.0a.
2242 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2243 the previous change.
2245 Various maintainer cleanups.
2246 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2247 conftest*, for benefit of CVS commands run at the same time as
2248 "configure". Add build-aux, since "bootstrap" now creates it and
2250 * Makefile.cfg (move_if_change): Remove.
2251 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2252 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

2257 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2259 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2260 this is now the recommended name.
2261 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2262 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2263 ylwrap. These files now go into build-aux.
2264 * config/move-if-change: Remove.
2265 * config/prev-version.txt: Bump from 1.75 to 2.0.
2267 * bootstrap: Add stdio-safer, unistd-safer modules.
2268 Remove m4/glibc2.m4 (introduced by latest gnulib, but

2271 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2272 * lib/subpipe.c: Include "unistd-safer.h".
2273 (create_subpipe): Make sure all the newly-created
2274 file descriptors are > 2, so that diagnostics don't
2275 get sent down them (which might cause Bison to hang, in theory).
2276 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2277 * src/files.c (xfopen): Use fopen_safer, not fopen.
2279 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2280 yesterday's yacc.c fix.
2282 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

2286 Fix a destructor bug reported by Wolfgang Spraul in
2287 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2288 * data/yacc.c (yyabortlab): Don't call destructor, and
2289 don't set yychar to EMPTY.
2290 (yyoverflowlab): Don't call destructor.
2291 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2292 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2293 since we no longer output the message "discarding lookahead token
2296 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2298 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2299 fix a small glitch in debugging output.
2300 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2301 after YY_SYMBOL_PRINT where needed.
2303 (struct yyGLRState): Add some comments.
2304 (struct yySemanticOption): Add some comments.
2305 (union yyGLRStackItem): Add comment.
2307 (yymergeOptionSets): Correct this to properly perform the union,
2308 avoiding infinite reported by Michael Rosien.

2352 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
2354 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
2355 Problem reported by Ralf Menzel.
2357 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2359 * tests/actions.at: Test that stack overflow invokes destructors.
2360 From Marcus Holland-Moritz.
2361 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2363 (yyreturn): to here. That way, destructors are called properly
2364 even if the stack overflows, or the user calls YYACCEPT or
2365 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2366 (yyoverflowlab): Destroy the lookahead.
2368 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2370 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2372 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2374 * NEWS: Bison-generated C parsers no longer quote literal strings
2375 associated with tokens.
2376 * src/output.c (prepare_symbols): Don't escape strings,
2377 since users don't want to see C escapes.
2378 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2380 * tests/input.at (Torturing the Scanner): Likewise.
2381 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2383 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2385 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2386 the data size is known to be too small and we can't increase it.
2387 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2389 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2391 * src/parse-gram.y: Include quotearg.h.
2392 (string_as_id): Quote $1 before using it as a key, since the
2393 lexer no longer quotes it for us.
2394 (string_content): Don't strip quotes, since lexer no longer
2396 * src/scan-gram.l: Include quotearg.h.
2398 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2399 a key, since the rest of the lexer doesn't quote it.
2400 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2401 * tests/regression.at (Token definitions): Check for backslashes
2404 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2405 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2406 (yyparse): Revamp code to generate long syntax error message, to
2407 make it easier to translate, and to avoid problems with arithmetic
2408 overflow. Change "virtual memory" to "memory" in diagnostic, since
2409 we don't know whether the memory is virtual.
2411 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2413 * NEWS: Bison-generated C parsers now use the _ macro to
2415 * data/yacc.c (_) [!defined _]: New macro.
2416 All English strings wrapped inside this macro.
2417 * doc/bison.texinfo (Bison Parser): Document _.
2418 * po/POTFILES.in: Include src/parse-gram.c, since it now
2419 includes translateable strings that parse-gram.y doesn't.
2421 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2423 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2424 reverting the 2004-10-11 change to this function.
2425 (symbol_check_alias_consistency): Don't call symbol_type_set
2426 if the type name is already correct.
2427 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2429 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2431 * tests/regression.at (Token definitions): Don't use a token named
2432 c, as that generates a "#define c ..." that runs afoul of buggy
2433 stdlib.h that uses the identifier c as a member of struct
2434 drand48_data. Problem reported by Horst Wente.
2436 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2438 * bootstrap: Change translation URL from
2439 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2440 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2441 redirection glitches. Problem reported by twlevo@xs4all.nl.
2443 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2445 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2446 after operands; POSIX says this isn't portable for the c99 command.
2448 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2450 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2451 immediately if a data overrun has occurred; this may help us track
2452 down what may be a spurious failure on MacOS.
2454 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2456 Respond to problems reported by twlevo@xs4all.nl.
2458 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
2460 * src/vcg.h: Comment fix.
2461 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2462 (G_CMAX): Change to -1 instead of INT_MAX.
2464 * data/yacc.c (yyparse): Omit spaces before #line.
2466 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2468 * src/tables.c (state_number_to_vector_number): Put it inside an
2469 "#if 0", since it's not currently used. Problem reported by
2472 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2474 * src/output.c (escaped_output): Renamed from
2475 escaped_file_name_output, since we now use it for symbol tags as
2476 well. All uses changed.
2477 (symbol_destructors_output, symbol_printers_output):
2478 Escape symbol tags too.
2479 Problem reported by Matyas Forstner in
2480 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2482 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2484 * src/output.c (user_actions_output, token_definitions_output,
2485 symbol_destructors_output, symbol_printers_output): Likewise.
2486 * src/reader.c (prologue_augment): Likewise.
2487 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2489 * src/vcg.c (output_edge): Don't quote linestyle arg.
2490 Problem reported by twlevo@xs4all.nl.
2492 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2494 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2495 example, reported by Derek M Jones. Also, make the example even
2496 more outrageous, to better illustrate how bad the problem is.
2498 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2500 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2501 putsym. Typo reported by Sebastian Piping.
2503 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2505 * doc/bison.texinfo (Language and Grammar): some -> same
2506 (Epilogue): int he -> in the
2507 Typos reported by Sebastian Piping via Justin Pence.
2509 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2511 * tests/glr-regression.at (Improper handling of embedded actions
2512 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2513 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2514 with dollar signs in test names.
2515 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2516 for a similar reason.
2518 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2520 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2521 wants to redefine G_VIEW.
2523 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
2525 * src/vcg.c (get_view_str): Remove case for normal_view.
2526 Problem reported by twlevo@xs4all.nl.
2528 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
2530 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
2531 Problem reported by twlevo@xs4all.nl.
2533 * doc/bison.texinfo: Change @dircategory from "GNU programming
2534 tools" to "Software development". Requested by Richard Stallman
2537 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
2539 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
2540 Problem reported by twlevo@xs4all.nl.
2542 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2544 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2545 keyword; it's not needed with modern compilers, and it doesn't
2546 affect correctness with older compilers. Suggested by
2549 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2551 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2552 gcc -Wswitch-default.
2553 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2554 * data/yacc.c (yyparse): Likewise.
2556 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2558 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2559 already. Let config.h define any nonstandard values.
2561 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2563 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2564 for the benefit of slower hosts. Problem reported by
2567 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2569 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2570 being defined and not used.
2571 * data/lalr1.cc (yyparse): Likewise.
2572 Use "if (false)" rather than "if (0)".
2574 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2576 * TODO: Mention that we should allow NUL bytes in tokens.
2578 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2580 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2581 Problem reported by Hans Aberg.
2583 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2585 * src/getargs.c (version): Happy new year; update overall
2586 program copyright date from 2004 to 2005.
2588 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2589 Problem reported by Hans Aberg.
2590 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2591 (Output file names.): Add a test for the case when standard output
2594 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2596 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2597 to fix an oversight in the Bison 2.0 manual.
2599 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2601 * NEWS: Version 2.0. Reformat the existing news items since
2602 1.875, so that related items are grouped together.
2603 * configure.ac (AC_INIT): Bump version to 2.0.
2604 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2606 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2607 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2608 otherwise, we're not testing alloca. Unfortunately there's no
2609 simple way to consult HAVE_ALLOCA here.
2611 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2614 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2615 hand. This avoids a warning about comparing int to size_t when
2616 GCC warnings are enabled.
2618 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2620 * NEWS: Bison-generated parsers no longer default to using the
2621 alloca function (when available) to extend the parser stack, due
2622 to widespread problems in unchecked stack-overflow detection.
2623 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2624 responsibility to set it to a positive value. This lets the user
2625 specify a value that is not a preprocessor constant.
2626 * data/yacc.c (YYMAXDEPTH): Likewise.
2627 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2628 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2629 to be a compile-time constant. However, explain the constraints on it.
2630 Also, explain the constraints on YYINITDEPTH.
2631 (Table of Symbols): Explain that alloca is no longer the default.
2632 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2635 * doc/bison.texinfo (Location Default Action): Mention that n must
2636 be zero when k is zero. Suggested by Frank Heckenbach.
2638 2004-12-22 Akim Demaille <akim@epita.fr>
2640 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2641 (parser::state_type, parser::semantic_type, parser::location_type):
2642 Private, not public.
2643 (parser::parse): Return ints, not bool.
2644 Returning a bool introduces a problem: 0 corresponds to false, and
2645 it seems weird to return false on success. Returning true changes
2646 the conventions for yyparse.
2647 Alternatively we could return void and send an exception.
2648 There is no clear consensus (yet?).
2649 (state_stack, semantic_stack, location_stack): Rename as...
2650 (state_stack_type, semantic_stack_type, location_stack_type): these.
2651 Private, not public.
2652 * tests/c++.at: New.
2653 * tests/testsuite.at, tests/Makefile.am: Adjust.
2655 2004-12-21 Akim Demaille <akim@epita.fr>
2657 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
2659 2004-12-21 Akim Demaille <akim@epita.fr>
2661 Don't impose std::string for filenames.
2663 * data/lalr1.cc (b4_filename_type): New.
2664 (position::filename): Use it.
2665 (parser.hh): Move the inclusion of stack.hh and location.hh below
2666 the user code, so that needed headers for the filename type can be
2668 Forward declare them before the user code.
2669 * tests/Makefile.am (check-local, installcheck-local): Pass
2670 TESTSUITEFLAGS to the TESTSUITE.
2672 2004-12-20 Akim Demaille <akim@epita.fr>
2674 Use more STL like names: my_class instead of MyClass.
2676 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
2677 (SemanticStack, SemanticType, StateStack, StateType)
2678 (TokenNumberType, Stack, Slice, Traits, Parser::location)
2679 (Parser::value): Rename as...
2680 (location_stack, location_type, rhs_number_type, semantic_stack)
2681 (semantic_type, state_stack, state_type, token_number_type, stack)
2682 (slice, traits, parser::yylloc, parser::yylval): these.
2684 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
2686 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
2688 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
2689 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2691 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
2693 Remove uses of 'short int' and 'unsigned short int'. This raises
2694 some arbitrary limits. It uses more memory but nowadays that's
2695 not much of an issue.
2697 This change does not affect the generated parsers; that's a different
2698 task, as some users will want to conserve memory there.
2700 Ideally we should use size_t to represent all object counts, and
2701 something like ptrdiff_t to represent signed differences of object
2702 counts; but that will require more code-cleanup than I have the
2703 time to do right now.
2705 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
2706 Use size_t, not int or short int, to count objects.
2707 * src/closure.c (nritemset, closure): Likewise.
2708 * src/closure.h (nritemset, closure): Likewise.
2709 * src/nullable.c (nullable_compute): Likewise.
2710 * src/print.c (print_core): Likewise.

2717 * src/output.c (prepare_rules): Likewise.
2718 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
2719 errs, reductions): Likewise.
2720 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
2722 * src/tables.c (vector_number, tally, action_number,
2723 ACTION_NUMBER_MINIMUM): Likewise.
2724 * src/output.c (muscle_insert_short_int_table): Remove.
2726 2004-12-17 Akim Demaille <akim@epita.fr>
2728 * data/lalr1.cc: Extensive Doxygenation.
2729 (error_): Rename as...
2730 (error): this, since it is visible to the user.
2732 (Parser::message): Now an automatic variable from...
2733 (Parser::yyreport_syntax_error_): here.
2734 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
2736 * tests/input.at: Escape $.
2738 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
2740 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
2741 Parenthesize rhs to avoid obscure problems with mistakes like
2742 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
2743 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2744 b4_rhs_location): Likewise.
2745 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2746 b4_rhs_location): Likewise.
2748 2004-12-16 Akim Demaille <akim@epita.fr>
2750 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
2751 yacc.c: be sure to stay within yycheck_.
2752 * tests/actions.at: Re-enable C++ tests.
2754 2004-12-16 Akim Demaille <akim@epita.fr>
2756 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
2759 2004-12-16 Akim Demaille <akim@epita.fr>
2761 Use #define to handle the %name-prefix.
2763 * data/glr.c, data/yacc.c: Comment changes.
2764 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
2765 so that one can refer to yylex in the parser file, and have it
2766 renamed, as is the case with other skeletons.
2768 2004-12-16 Akim Demaille <akim@epita.fr>

2790 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
2792 Fix some problems reported by twlevo at xs4all.
2793 * src/symtab.c (symbol_new): Report an error if the input grammar
2794 contains too many symbols. This is better than calling abort() later.
2795 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
2796 (struct node, struct graph):
2797 Rename member expand to stretch. All uses changed.
2798 (struct graph): Remove member layoutalgorithm. All uses removed.

2804 2004-12-15 Akim Demaille <akim@epita.fr>
2806 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
2807 Add more Doxygen comments.
2808 (symprint_, stack_print_, reduce_print_, destruct_, pop)
2809 (report_syntax_error_, translate_): Rename as...
2810 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
2811 (yypop_, yyreport_syntax_error_, yytranslate_): this.
2813 2004-12-15 Akim Demaille <akim@epita.fr>
2815 * data/lalr1.cc (lex_): Rename as...
2817 Move the trace here.

2826 (yydebug_): so that the parser's internals are always in the yy*
2829 (b4_parse_param_decl): Remove the leading comma as it is now only
2830 called as unique argument list.
2831 (Parser::Parser): Remove the constructor accepting a location and
2832 an initial debugging level.
2833 Remove from the other ctor the argument for the debugging level.
2834 (debug_level_type, debug_level, set_debug_level): New.
2836 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
2839 2004-12-15 Akim Demaille <akim@epita.fr>
2841 Remove b4_root related material: failure experiment
2842 (which goal was to allow to derive from a class).
2844 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
2845 definitions and uses.
2847 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
2849 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
2850 not 2, since it's not portable to subtract 1 from the start of an
2851 array. The new item 0 is never set or used. All uses changed.
2853 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
2854 the default definition of YYLLOC_DEFAULT. Problem reported
2855 by Frank Heckenbach.
2857 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
2859 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
2860 the normal case and one for the error case. Just use the
2861 first one uniformly. Problem reported by Frank Heckenbach.
2862 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
2863 use exactly the same macro in both places.
2864 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
2865 so that the normal-case YYRHSLOC works for the error case too.
2867 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
2868 (YYLLOC_DEFAULT): Use the same macro as glr.c.
2869 * doc/bison.texinfo (Location Default Action): Don't claim that
2870 we have an array of locations. Use the same macro for both glr
2871 and lalr parsers. Mention YYRHSLOC. Mention what happens when
2874 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2876 * HACKING: Update email addresses to send announcements to.
2878 * configure.ac (AC_INIT): Bump version to 1.875f.
2880 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2882 * NEWS: Version 1.875e.
2883 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
2885 * src/scan-skel.l: Include "complain.h", for "fatal".
2887 * src/relation.h (relation_print, relation_digraph):
2888 Relation sizes are of type relation_node, not size_t (this is
2889 merely a doc fix, since the two types are equivalent).
2890 (relation_transpose): Relation sizes are of type relation_node,
2892 * src/relation.c: Likewise.
2893 (top, infinity): Now of type relation_node, not int.
2894 (traverse, relation_transpose): Use relation_node, not int.
2896 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
2897 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
2898 (yyparse): Remove unused local introduced in 2004-10-25 patch.
2900 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
2901 specifying whether the test should be skipped. Use it tp
2902 specify that the [%defines %skeleton "lalr1.cc"] tests currently
2903 fail on some hosts, and should be skipped.
2905 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
2907 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
2908 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
2909 unless otherwise specified below.
2911 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
2912 to allocate kernel_base, kernel_items, kernel_size, since
2913 they needn't be initialized to 0.
2914 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
2915 * src/closure.c (new_closure): Likewise, for itemset.
2916 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
2917 * src/lalr.c (set_goto_map): Likewise, for temp_map.
2918 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
2919 (build_relations): Likewise for edge, states1, includes.
2920 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
2921 * src/reader.c (packgram): Likewise, for ritem, rules.
2922 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
2923 * src/relation.c (relation_digraph): Likewise for VERTICES.
2924 (relation_transpose): Likewise for new_R, end_R.
2925 * src/symtab.c (symbols_token_translations_init): Likewise for
2927 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
2928 (token_actions): Likewise for yydefact, actrow, conflrow,
2930 (save_column): Likewise for froms[symno], tos[symno].
2931 (goto_actions): Likewise for state_count.
2932 (pack_table): Likewise for base, pos, check.
2933 (tables_generate): Likewise for width.
2935 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
2936 for initial core. Just have a separate core, so we needn't worry
2937 about whether kernel_size and kernel_base are initialized.
2939 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
2940 kernel_size, kernel_items): Remove unnecessary initialization.
2941 * src/conflicts.c (conflicts): Likewise.
2942 * src/derives.c (derives): Likewise.
2943 * src/muscle_tablc (muscle_insert): Likewise.
2944 * src/relation.c (relation_digraph): Likewise.
2945 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
2946 conflrow, conflict_table, conflict_list, table, check):
2949 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
2950 This is because all callers pass unsigned int.
2951 * src/closure.h (new_closure): Likewise.
2953 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
2954 (build_relations): Initialize includes[i] in all cases.
2955 * src/reader.c (packgram): Always initialize rules[ruleno].prec
2956 and rules[ruleno].precsym. Initialize members in order.
2957 * src/relation.c (relation_transpose): Always initialize new_R[i]
2959 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
2961 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
2962 conflict_list[0] was always 0, but now it isn't initialized.
2964 * src/table.c (table_grow): When conflict_table grew, the grown
2965 area wasn't cleared. Fix this.
2967 * lib/.cvsignore: Add strdup.c, strdup.h.
2968 * m4/.cvsignore: Add strdup.m4.
2970 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
2972 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
2973 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
2974 GOTO_NUMBER_MAXIMUM, since we occasionally compute
2975 ngotos + 1 without checking for overflow.
2976 (build_relations): Use END_NODE, not -1, to denote end of edges.
2977 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
2978 build_relations): Use goto_number, not int, for goto numbers.
2979 * src/tables.c (save_column, default_goto): Likewise.
2981 2004-11-23 Akim Demaille <akim@epita.fr>
2983 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
2984 of #defining from yystype.
2985 Don't typedef yystype, C++ does not need it.
2986 This lets it possible to forward declare it as union.
2988 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
2990 * bootstrap (gnulib_modules): Add extensions.
2991 Problem reported by Jim Meyering.
2993 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
2995 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
2996 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
2997 src/system.h, src/tables.c: XFREE -> free, to accommodate
2998 recent change to gnulib xalloc.h.
2999 Problem reported by Jim Meyering.
3001 2004-11-17 Akim Demaille <akim@epita.fr>
3003 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
3005 2004-10-28 Akim Demaille <akim@epita.fr>,
3006 Alexandre Duret-Lutz <adl@gnu.org>
3008 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3011 Use it instead of cdebug_.
3012 (Parser::debug_stream, Parser::set_debug_stream): New.
3013 (Parser::symprint_): Define cdebug_ for temporary backward
3015 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3018 2004-11-17 Akim Demaille <akim@epita.fr>
3020 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
3021 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
3022 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
3023 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
3025 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
3027 * data/glr.c (yyloc_default): Remove; not used.
3028 Problem reported by Frank Heckenbach.
3030 2004-10-25 Akim Demaille <akim@epita.fr>
3032 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3033 Introduce another definition to address simple location arrays.
3034 (yyGLRStack): New member: yyerror_range.
3035 (yyrecoverSyntaxError, yyparse): Update it.
3036 (yyrecoverSyntaxError): Use it when shifting the error token to
3037 have an accurate range, equivalent to the one computed by both
3038 yacc.c and lalr1.cc.
3039 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3040 that column numbers start at column 0, as per GNU Coding
3041 Standards, the others tests, and the doc.
3042 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3043 Adjust to the above change (first column is 0).
3044 And adjust the location of the "<error>", now covering the whole
3047 2004-10-22 Akim Demaille <akim@epita.fr>
3048 and Paul Eggert <eggert@cs.ucla.edu>
3050 Remove some arbitrary limits on goto numbers and relations.
3051 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3052 initial values, since they're never used.
3053 (set_goto_map): ngotos is now unsigned, so test for overflow
3054 by seeing whether it wraps around to zero.
3055 * src/lalr.h (goto_number): Now size_t, not short int.
3056 (GOTO_NUMBER_MAXIMUM): Remove.
3057 * src/relation.c (relation_print, traverse, relation_transpose):
3058 Check for END_NODE rather than looking at sign.
3059 * src/relation.h (END_NODE): New macro.
3060 (relation_node): Now size_t, not short int.
3062 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3064 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3065 keyword, not an identifier. Problem reported by Baron Schwartz in
3066 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3068 2004-10-11 Akim Demaille <akim@epita.fr>
3070 * src/symtab.c (symbol_check_alias_consistency): Also check
3071 type names, destructors, and printers.
3072 Reported by Alexandre Duret-Lutz.
3073 Recode the handling of associativity and precedence in terms
3074 of symbol_precedence_set.
3075 Accept no redeclaration at all, not even equal to the previous
3077 (redeclaration): New.
3078 Use it to factor redeclaration complaints.
3079 (symbol_make_alias): Don't set the type of the alias, let
3080 symbol_check_alias_consistency do it as for other features.
3081 * src/symtab.h (symbol): Add new member prec_location, and
3083 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3084 * tests/input.at (Incompatible Aliases): New.
3086 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3088 .cvsignore fixes to accommodate gnulib changes,
3089 and the practice of naming build directories "_build".
3090 * .cvsignore: Add "_*". Sort.
3091 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3092 * m4/.cvsignore: Add "*_gl.m4".
3094 2004-10-06 Akim Demaille <akim@epita.fr>
3096 * src/parse-gram.y (add_param): Fix the truncation of trailing
3099 2004-10-05 Akim Demaille <akim@epita.fr>
3101 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3102 whether the reducion was empty or not. This leaves room to
3103 improve the use of YYLLOC_DEFAULT in such a case.
3104 lalr1.cc is still experimental, so changing this is acceptable.
3105 And finally, there are probably not many users who changed the
3106 handling of locations in GLR, so changing is admissible too.
3108 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3109 empty reduction, set @$ to an empty location ending the previously
3111 Adjust uses to make sure the code is triggered on empty
3113 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3114 expected output: empty reductions have empty locations.
3116 2004-09-29 Akim Demaille <akim@epita.fr>
3118 * data/lalr1.cc: Move towards a more standard C++ coding style
3119 for templates: Class < T > -> Class<T>.
3121 2004-09-29 Akim Demaille <akim@epita.fr>
3123 * data/lalr1.cc: Reinstall the former ctor, for sake of
3124 compatibility, but warn it will be removed.
3125 Move towards a more standard C++ coding style (i.e., type *var ->
3128 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3130 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3131 since it's less likely to work if NULs are involved in the future.
3133 2004-09-27 Akim Demaille <akim@epita.fr>
3135 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3137 2004-09-27 Akim Demaille <akim@epita.fr>
3139 * data/lalr1.cc (b4_parse_param_decl_1): New.
3140 (b4_parse_param_decl): Use it to have different names between attribute
3142 (b4_cc_constructor_call): Likewise.
3144 2004-09-24 Akim Demaille <akim@epita.fr>
3146 * src/parse-gram.y (add_param): Strip the leading and trailing
3147 blanks from a formal argument declaration.
3148 (YY_LOCATION_PRINT): New.
3150 2004-09-24 Akim Demaille <akim@epita.fr>
3152 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3155 2004-09-24 Akim Demaille <akim@epita.fr>
3157 * doc/bison.texinfo (Table of Symbols): Sort.
3159 2004-09-21 Akim Demaille <akim@epita.fr>
3161 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3162 the useless parentheses.
3163 Suggested by Paul Eggert.
3165 2004-09-20 Akim Demaille <akim@epita.fr>
3167 Let the initial-action act on the look-ahead, and use it for the
3168 "initial push" (corresponding to an hypothetical beginning-of-file).
3169 And let lalr1.cc honor %initial-action.
3171 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3173 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3174 (Parser::Parser): Remove the ctor that used to initialize it.
3175 (Parser::parse): Like in the other skeletons, issue the "starting
3176 parse" message before any action.
3177 Honor %initial-action.
3178 Initialize the stacks with the lookahead.
3179 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3181 Push them in the stacks.
3182 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3184 2004-09-20 Akim Demaille <akim@epita.fr>
3186 * doc/bison.texinfo (Initial Action Decl): New.
3188 2004-09-20 Akim Demaille <akim@epita.fr>
3190 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3191 clearer criterion to define it.
3192 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3193 When reducing on an empty RHS, use the latest stacked location as
3195 yylloc is not always available.
3196 * data/glr.c: Likewise.
3197 Also, honor initial-actions.
3199 2004-09-20 Akim Demaille <akim@epita.fr>
3201 * data/yacc.c (YY_LOCATION_PRINT): New.
3202 Define when we know YYLTYPE's structure, i.e., when the default
3203 YYLLOC_DEFAULT is used.
3204 * data/c.m4 (b4_yysymprint_generate): Use it.
3205 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3206 value of the result.
3207 (error_start_): Replace with...
3208 (error_range_): this location array.
3209 This allows to replace code relying on the implementation of
3210 locations by portable code.
3211 * data/yacc.c (yylerrsp): Replace with...
3212 (yyerror_range): this.
3213 Every time a token is popped, update yyerror_range[0], to have an
3214 accurate location for the error token.
3215 * data/glr.c (YY_LOCATION_PRINT): New.
3216 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3217 deference a pointer.
3218 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3219 report the location in %printers.
3221 * src/scan-skel.l: Instead of abort, report error messages to ease
3222 understanding skeleton scanning failures.
3224 2004-09-16 Akim Demaille <akim@epita.fr>
3226 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3227 (iterator, const_iterator): these, to be more in the C++ spirit.
3228 Also, return reverse iterators so that when displaying the stack
3229 we display its bottom first.
3230 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3232 We should probably use vector here though.
3234 2004-09-16 Akim Demaille <akim@epita.fr>
3236 Have more complete shift traces.
3238 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3239 to report Shifts instead of ad hoc YYDPRINTF invocations,
3240 including for the error token.
3241 * data/lalr1.cc (symprint_): Output the location.
3242 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3243 output the location within the %printer.
3244 Activate GLR tests, at least to make sure they compile properly.
3245 They still don't pass though.
3246 * tests/calc.at: Adjust expect verbose output, since now "Entering
3247 state..." is on a different line than the "Shifting" message.
3249 2004-09-08 Akim Demaille <akim@epita.fr>
3251 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3252 Bison directive from the Bison file to the invocation of this
3253 macro, so that these directives are passed to
3254 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3255 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3256 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3257 the extra Bison directives instead of the whole series.
3258 Change the grammar so that there are recoverable errors, and
3259 unrecoverable errors. Now we can have the parser give up before
3260 consuming the whole input. As a result we now can observe that
3261 the lookahead is freed when needed.
3262 Change the parser source to parse argv[1] instead of a hard coded
3264 Simplify yylex, and give a value and location to EOF.
3265 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3266 passed directives already coded in the file.
3267 Add some tests to check the location of "error".
3268 For some tests, the C++ parser is correct, and not yacc.c.
3269 For other tests, they provide different, but unsatisfying, values,
3270 so keep the C++ value so that at least one parser is "correct"
3271 according to the test suite.
3272 (Actions after errors): Remove, this is subsumed by the
3273 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3275 2004-09-06 Akim Demaille <akim@epita.fr>
3277 * data/lalr1.cc: Adjust the indentation of the labels.
3281 2004-09-06 Akim Demaille <akim@epita.fr>
3283 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3284 argument, an informative message.
3285 Call YY_SYMBOL_PRINT.
3286 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3287 * data/lalr1.cc (destruct_): Likewise.
3288 In addition, no longer depend on b4_yysymprint_generate and
3289 b4_yydestruct_generate to generate these functions, do it "by
3292 2004-09-03 Akim Demaille <akim@epita.fr>
3294 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3295 invoked, yydestruct the lookahead.
3296 * tests/calc.at (Calculator $1): Update the expected lengths of
3297 traces: there is an added line for the discarded lookahead.
3298 * doc/bison.texinfo (Destructor Decl): Some rewording.
3299 Define "discarded" symbols.
3301 2004-09-02 Akim Demaille <akim@epita.fr>
3303 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3305 2004-09-02 Akim Demaille <akim@epita.fr>
3307 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3308 (YYDSYMPRINTF): Rename as...
3309 (YY_SYMBOL_PRINT): this.
3310 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3312 Use it instead of direct symprint_ calls.
3313 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3316 2004-09-02 Akim Demaille <akim@epita.fr>
3318 * data/lalr1.cc (b4_yysymprint_generate): New.
3319 (symprint_): New member function, defined when YYDEBUG.
3320 Use it consistently instead of token/nterm debugging output by

3338 * bootstrap (gnulib_modules): Add xalloc-die.
3339 Set LC_ALL=C so that file names sort consistently.
3340 Prefer the gnulib copies of gettext.m4, glibc21.m4,

3342 uintmax_t.m4, ulonglong.m4.
3343 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,

3371 UNION-FLAG. All callers changed.
3372 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3373 Use type char, not unsigned int, when declaring an array of char;
3374 this lets us remove a cast.

3377 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3379 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3380 GLR writeups. E.g., avoid frenchspacing and the future tense,

3447 C++ compiler. (trivial change)
3449 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
3451 Spent a few hours checking out which prerequisite versions the
3452 current sources actually require. I went all the way back to
3453 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3454 a seemingly endless set of combinations of versions more recent
3455 than that. The bottom line is that the current sources require
3456 fairly recent versions of the build tools, and it'll be some work
3458 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3459 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3460 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3461 Add comments explaining why those particular versions are

3465 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3466 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3468 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3469 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3471 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3473 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3474 0.11.5. Suggested by Bruno Haible.
3475 * bootstrap: Remove gettext version checking.
3477 * doc/bison.texinfo (Decl Summary): Also mention that %union
3478 can depend on prerequisite types. Problem reported by Tim
3481 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3483 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3484 * README-alpha: Don't tell people not to package this.
3486 * bootstrap: Don't assume $(...) works; use `...` instead.
3487 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3490 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3491 put into the -d output file, and mention what to do if YYSTYPE is
3494 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3496 Undo change made earlier today: it caused autopoint to not bring
3497 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3500 * bootstrap: Check that gettext version matches what's in
3501 configure.ac. Warn users to ignore robots.txt ERROR 404.
3502 * bootstrap: Undo today's earlier change (logged below).
3503 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3505 The gettext version checking is causing more trouble than it's
3506 curing; remove it. Problem reported by Paul Hilfinger.
3508 * bootstrap: Issue a warning that one can expect a message
3509 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3510 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3512 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3514 Ensure that the C++ compiler used for testing actually works on a
3515 simple test program; if not, skip the C++-related tests. Problem
3516 reported by Vin Shelton in:
3517 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

3526 * data/glr.c (yylloc): Output this macro even if locations are not
3527 being generated, as the GLR parser needs it even in that case.
3528 Problem reported by Troy A. Johnson
3529 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3531 * configure.ac (AC_INIT): Update to 1.875e.

3537 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
3539 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3540 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3541 lalr1.cc runs afoul of the first, and the last two are no longer
3542 supported by GCC 3.4.0.
3543 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3544 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3546 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
3548 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
3549 unsigned int, for compatibility with latest gnulib hash module.

3570 Fix typo by replacing $1 with $option.
3571 Remove more 'intl'-related files.
3572 Don't DEFUN AM_INTL_SUBDIR twice.
3574 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
3575 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,

3581 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
3582 * src/.cvsignore: Add *.output.
3584 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3585 gets copied to the output file.
3587 2004-04-28 Paul Eggert <eggert@twinsun.com>
3589 Get files from the gnulib and po repositories, instead of relying
3590 on them being in our CVS. Upgrade to latest versions of gnulib
3593 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3594 * bootstrap: Bootstrap from gnulib and po repositories.
3595 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3596 * README-cvs: Document these changes. Remove version numbers from
3597 mentions of build tools, since they change so often. Mention Flex.
3599 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
3600 (gl_USE_SYSTEM_EXTENSIONS): Add.
3601 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3602 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3604 (AC_ISC_POSIX): Remove; we no longer support this
3605 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3606 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3607 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3608 Do not check for C89 headers, except for locale.h which is used
3609 by the Yacc library and must port to K&R hosts.
3610 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3611 Do not check for C89 functions, except for setlocale which is
3612 used by the Yacc library.
3613 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
3614 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
3615 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

3617 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
3618 AM_GNU_GETTEXT): Remove; now done by:
3619 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
3620 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
3623 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3624 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3625 Define to empty, as gnulib.mk will do the rest for us.
3626 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
3628 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
3629 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
3631 * src/files.c: Include gnulib's xstrndup.h.
3633 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
3634 (REALLOC): Use xnrealloc, for likewise.
3635 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

3660 Remove, as these files are now generated automatically
3661 by bootstrap or automake.
3663 * po/ChangeLog: Remove: all but one entry was a duplicate

3691 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
3692 case, as stos_ is now used by destructors due to the 2004-02-09
3695 Remove more K&R C support.
3696 * lib/libiberty.y (PARAMS): Remove. All uses removed.

3723 test whether it can stand alone.

3726 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

3730 the union, because empty unions aren't allowed in C. Caught
3733 2004-04-13 Jim Meyering <jim@meyering.net>

3820 chatty, reported by Guido Trentalancia in
3821 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

3837 token so that it covers all the discarded tokens.
3838 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
3839 it can be called with `%skeleton "lalr1.cc"', and do that.
3841 2004-02-02 Paul Eggert <eggert@twinsun.com>
3843 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
3844 $(top_srcdir)/lib and ../lib. This fixes a bug reported
3845 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
3846 There's no need to mention top_builddir since Automake does that
3848 (INCLUDES): Remove, as Automake says it's obsolescent.
3849 Contents migrated into AM_CPPFLAGS as described above.

3871 * tests/local.at: Require Autoconf 2.59's Autotest.

3905 2003-10-04 Paul Eggert <eggert@twinsun.com>
3907 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
3908 non-modifiable lvalue, instead of a modifiable one.
3909 * doc/bison.texinfo (Actions): Document that $$ can
3910 be assigned to. Do not claim that $$ and $N are

3969 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
3971 2003-08-25 Akim Demaille <akim@epita.fr>
3973 When reducing initial empty rules, Bison parser read an initial
3974 location that is not defined. This results in garbage, and that
3975 affects Bison's own parser. Therefore we need (i) to extend Bison
3976 to support a means to initialize this location, and (ii) to use
3977 this CVS Bison to fix CVS Bison's parser.
3979 * src/reader.h, reader.c (epilogue_augment): Remove, replace
3981 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

4016 error recovery loops. This patch is based on
4017 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4018 Also, augment the similarity between lalr1.cc and yacc.c.
4019 Note: the locations of error recovery rules are not correct yet.
4021 * data/lalr1.cc: Comment changes to augment the similarity between
4022 lalr1.cc and yacc.c.
4023 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4024 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4025 yyerrlab), when hitting EOF, pop the whole stack here instead of
4026 merely falling thru the default error handling mechanism.
4027 (yyerrorlab): New label, with the old contents of YYERROR,
4028 plus the following change: pop the stack of rhs corresponding
4029 to the production that invoked YYERROR. That is how Yacc
4030 behaves (required by POSIX).
4031 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4034 2003-08-25 Akim Demaille <akim@epita.fr>
4036 Tune local.at so that people can "autom4te -l autotest calc.at -o
4037 calc" for instance, to extract a sub test suite.
4039 * tests/testsuite.at: Move the initialization, Autotest version
4040 requirement, and AT_TESTED invocation into...
4041 * tests/local.at: here.
4042 * tests/testsuite.at: Include it for compatibility with Autoconf
4044 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should

4051 The returned value is now stored in *YY0. All callers changed.
4052 * src/output.c (merge_output): Adjust to the above change.
4054 2003-07-26 Paul Eggert <eggert@twinsun.com>
4056 * data/glr.c (YYASSERT): New macro.
4057 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4058 yyresolveStates, yyprocessOneStack):
4059 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
4060 Derived from a suggestion by Frank Heckenbach.
4062 2003-07-25 Paul Eggert <eggert@twinsun.com>
4064 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4065 for portability to K&R C (after ansi2knr, presumably). See
4066 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4067 by Frank Heckenbach, though I have omitted the structure-initialization
4068 part of his glr-knr.diff patch since I recall that the Portable
4069 C Compiler didn't require that change.
4071 Let the user specify how to allocate and free memory.
4072 Derived from a suggestion by Frank Heckenbach in
4073 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
4074 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
4075 All uses of free, malloc, realloc changed to use these macros,

4079 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
4081 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

4093 and return properly parenthesized result.
4094 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
4095 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4096 Remove unnecessary parentheses from uses.

4102 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
4103 yyreportTree): Do not assume that size_t is the same width as int,
4104 when printing sizes. Print sizes using an unsigned format.
4105 Problem reported by Frank Heckenbach in
4106 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
4108 Port to Forte Developer 7 C compiler.
4109 * data/glr.c (struct YYLTYPE): If locations are not being used,
4110 declare a single dummy member, as empty structs do not conform
4112 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
4113 the Forte Developer 7 C compiler complains that end-of-loop
4114 code is not reached.
4116 2003-06-17 Paul Eggert <eggert@twinsun.com>
4118 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to

4128 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
4129 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
4130 Don't use 'index' in comments, as it's a builtin fn on some hosts.

4160 arbitrary @ in node names.
4162 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4163 shouldn't be needed according to the gettext 0.12.1 documentation
4164 but which seem to be needed anyway: codeset.m4 glibc21.m4
4165 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

4189 the tests right now.
4190 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4191 yyerror are declared before use; C99 requires this.

4197 (yyrecoverSyntaxError): Correct the logic for setting and testing

4204 buffer overruns, corrupting state.
4206 * src/output.c (prepare_rules): Output max_left_semantic_context
4208 * src/reader.h (max_left_semantic_context): New variable declaration.

4215 Fixes to problems with location handling in GLR parsers reported by
4216 Frank Heckenbach (2003/06/05).
4218 * data/glr.c (YYLTYPE): Make trivial if locations not used.
4219 (YYRHSLOC): Add parentheses, and define only if locations used.
4220 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
4222 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
4223 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4225 * tests/cxx-type.at: Exercise location information; update tests
4226 to differentiate output with and without locations.
4227 Remove forward declarations of yylex and yyerror---caused errors
4228 because default YYLTYPE not yet defined.
4229 Change semantic actions to compute strings, rather than printing
4230 them directly (to test proper passing of semantics values). Change
4231 output to prefix notation and update test data and expected results.
4232 (yylex): Track locations.
4233 (stmtMerge): Return value rather than printing, and include arguments
4236 2003-06-03 Paul Eggert <eggert@twinsun.com>
4238 Avoid warnings generated by GCC 2.95.4 when Bison is
4239 configured with --enable-gcc-warnings.
4240 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
4241 yy::]b4_parser_class_name[::translate_,
4242 yy::Stack::operator[] (unsigned),
4243 yy::Stack::operator[] (unsigned) const,
4244 yy::Slice::operator[] (unsigned),
4245 yy::Slice::operator[] (unsigned) const):
4246 Rename local vars to avoid warnings.
4247 * tests/glr-regression.at (Improper handling of embedded actions
4248 and $-N in GLR parsers): Remove unused local variable from yylex.
4249 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4250 (void) as arg when not pure, since we now assume C89 when building
4251 Bison. Pacify GCC by using parameter.
4253 2003-06-02 Paul Eggert <eggert@twinsun.com>
4255 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4256 yy::Location::lines, yy::Location::columns): Rename arguments
4257 to avoid shadowing; this removes a warning generated by GCC 3.3.
4259 2003-06-01 Paul Eggert <eggert@twinsun.com>
4261 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4262 to g++, as GCC 3.3 complains if you do it.
4263 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4264 everything that WARNING_CFLAGS has, except omit warnings
4265 not suitable for C++.
4266 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4267 * tests/atlocal.in (CXXFLAGS): New var.
4268 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4270 Fix a GLR parser bug I reported in February; see
4271 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4272 The problem was that GLR parsers did not conform to the C standard,
4273 because actions like { $1 = $2 + $3; } expanded to expressions
4274 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4275 to a local variable. The C standard says that expressions
4276 like (var = f ()) + (var = f ()) have undefined behavior.
4277 Another problem was that GCC sometimes issues warnings that
4278 yyfill and its parameters are unused.
4280 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4282 (yyfill): New function.
4284 (yyuserAction): Change type of yynormal to bool, so that it matches
4285 the new yyfill signature. Mark it as possibly unused.
4288 Follow up on a bug I reported in February, where a Bison-generated
4289 parser can loop. Provide a test case and a fix for yacc.c. I
4290 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4291 The original bug report is in:
4292 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4294 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4295 macro's size was becoming unwieldy.
4296 (yyerrlab): Do not discard an empty lookahead symbol, as this
4297 might destroy garbage.
4298 (yyerrorlab): New label, with the old contents of YYERROR,
4299 plus the following change: pop the stack of rhs corresponding
4300 to the production that invoked YYERROR. That is how Yacc
4301 behaves, and POSIX requires this behavior.
4302 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4303 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4304 Define 'alarm' to do nothing if unistd.h is not available.
4305 Add a new rule "exp: '-' error;" to test the above change to
4306 data/yacc.c. Use 'alarm' to abort any test taking longer than
4307 10 seconds, as it's probably looping.
4308 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4309 Also, the new yacc.c generates two fewer diagnostics for an
4312 2003-05-24 Paul Eggert <eggert@twinsun.com>
4314 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4315 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4316 This fixes a problem reported by John Bowman when the Compaq/HP
4317 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4319 * data/yacc.c (union yyalloc): Likewise.
4320 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4322 Switch from 'int' to 'bool' where that makes sense.
4324 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
4325 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
4326 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
4327 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4328 Return or accept bool, not int. All callers changed.
4329 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
4330 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
4331 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

4347 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
4348 lbitset_xor_cmp): Likewise.
4349 * lib/bbitset.h: Include <stdbool.h>.
4350 (struct bitset_vtable): The following members now return bool, not
4351 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4352 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
4354 * src/conflicts.c (count_rr_conflicts): Likewise.
4355 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
4357 * lib/ebitset.c (ebitset_obstack_init): Likewise.
4358 * lib/lbitset.c (lbitset_obstack_init): Likewise.
4359 * src/getargs.c (debug_flag, defines_flag, locations_flag,
4360 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4361 graph_flag): Likewise.
4362 * src/getargs.h (debug_flag, defines_flag, locations_flag,

4368 * src/reader.h (typed): Likewise.
4369 * src/getargs.c (LOCATIONS_OPTION): New constant.
4370 (long_options, getargs): Use it.

4374 * src/tables.c (action_row, pack_vector): Likewise.
4375 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
4376 * src/output.c (prepare): Use it.
4377 * src/output.c (token_definitions_output,
4378 symbol_destructors_output, symbol_destructors_output): Use string,
4379 not boolean integer, to keep track of whether to output separator.
4380 * src/print_graph.c (print_core): Likewise.
4381 * src/state.c (state_rule_lookaheads_print): Likewise.
4383 * config/install-sh: Sync from automake 1.7.5.
4385 2003-05-14 Paul Eggert <eggert@twinsun.com>
4387 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4388 semicolon after a grammar declaration, in the interest of possible
4389 future changes to the Bison input language.
4390 Do not allow a stray semicolon at the start of the grammar.
4391 (rhses.1): Allow one or more semicolons after any rule, including
4392 just before "|" as required by POSIX.
4393 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4396 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4398 %parse-param support for lalr1.cc.
4400 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4401 b4_cc_constructor_calls, b4_cc_constructor_call,
4402 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4404 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4405 parse-param arguments.
4406 (yy::b4_parser_class_name): Declare instance variables to
4407 hold parse-param arguments.
4408 * tests/calc.at: s/value/semantic_value/ because value clashes
4409 with a member of yy::b4_parser_class_name. Adjust C++ code
4410 to handle %parse-param. Enable %parse-param test in C++.
4412 2003-05-12 Paul Eggert <eggert@twinsun.com>
4414 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4415 English a bit. Fix fclose typo. Change "const char" to "char
4416 const", and use ANSI C rather than K&R for "main". Suggest
4417 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4418 and suggest yy_switch_to_buffer.
4420 2003-05-05 Paul Eggert <eggert@twinsun.com>
4422 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4423 C89. This avoids a diagnostic on compilers that define __STDC__
4424 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4425 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4427 2003-05-03 Paul Eggert <eggert@twinsun.com>
4429 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4430 Do not overrun array bounds.
4431 This should fix a bug reported today by Olatunji Oluwabukunmi in
4432 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4434 2003-04-29 Akim Demaille <akim@epita.fr>
4436 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4437 * src/getargs.c, src/getargs.h: here, as bool, not int.
4438 (nondeterministic_parser): New.
4439 * src/parse-gram.y, src/scan-gram.l: Support
4440 %nondeterministic-parser.
4441 * src/output.c (prepare): Use nondeterministic_parser instead
4442 of glr_parser where appropriate.
4443 * src/tables.c (conflict_row, action_row, save_row)
4444 (token_actions, token_actions, pack_vector): Ditto.
4446 2003-04-29 Akim Demaille <akim@epita.fr>
4448 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4450 2003-04-29 Akim Demaille <akim@epita.fr>
4452 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4453 with %pure-parser and %locations to exercise the patch from Yakov
4456 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4458 * data/yacc.c: (b4_lex_param): Corrected for the case where
4459 %lex-param is provided and %pure-parser isn't.
4461 2003-04-27 Paul Eggert <eggert@twinsun.com>
4463 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4464 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4465 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4466 if it is not defined.
4467 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4469 2003-04-26 Paul Eggert <eggert@twinsun.com>
4471 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4472 Declare to be of type suitable for the ninf value itself, not of
4473 type suitable for the corresponding table, since the latter might
4474 be unsigned but the ninf value might be negative. This fixes a
4475 bug reported by Alexandre Duret-Lutz in
4476 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4478 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4479 invokes it. We shouldn't invoke it twice because it will attempt
4480 to put error.o in the archive twice. This fixes a glitch reported
4481 by Martin Mokrejs in
4482 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4484 2003-04-21 Paul Eggert <eggert@twinsun.com>
4486 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4489 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4491 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4492 Fix obvious typo that results in uncompilable GLR parsers
4493 when both %pure-parser and %locations are used. (trivial change)
4495 2003-04-17 Paul Eggert <eggert@twinsun.com>
4497 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4498 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4499 Do not insert the expected token via unput, as this runs afoul
4500 of a POSIX-compatibility bug in flex 2.5.31.
4501 All uses changed to BEGIN the parent state,
4502 since we no longer insert the expected token via unput.
4503 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4504 that is no longer emitted after the above change.
4506 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4507 the first one. This change is from Paul Hilfinger, and it fixes
4508 regression reported by Werner Lemberg in
4509 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4511 (resolve_sr_conflict): Don't invoke state_errs_set
4512 unless one or more tokens have been explicitly made errors.
4513 Otherwise, the above change causes Bison to abort.
4515 * tests/existing.at (GNU pic Grammar): New test case, taken from
4518 2003-03-31 Akim Demaille <akim@epita.fr>
4520 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4522 2003-03-31 Akim Demaille <akim@epita.fr>
4524 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4527 2003-03-31 Akim Demaille <akim@epita.fr>
4529 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4530 From Paul Hilfinger.
4532 2003-03-29 Akim Demaille <akim@epita.fr>
4534 * m4/error.m4: Do not put under dynamic conditions some code which
4535 expansion is under static control.
4537 2003-03-29 Akim Demaille <akim@epita.fr>
4539 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4541 2003-03-29 Akim Demaille <akim@epita.fr>
4543 * doc/bison.texinfo (Strings are Destroyed): New.
4545 2003-03-13 Paul Eggert <eggert@twinsun.com>
4547 * .cvsignore: Add configure.lineno.
4548 * src/.cvsignore: Add yacc.
4549 * tests/.cvsignore: Add testsuite.log.
4550 * doc/fdl.texi: Sync with latest FSF version.
4552 2003-03-12 Paul Eggert <eggert@twinsun.com>
4554 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4555 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4556 cursor, instead of leaving it undefined. This fixes a bug
4557 reported by Tim Van Holder in
4558 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4559 * tests/input.at (Torturing the Scanner): Test the scanner on
4560 an empty input file, which was Tim Van Holder's test case.
4562 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4563 <sys/resource.h> can be included, include sys/time.h and
4564 sys/times.h first, if available. This works around the SunOS
4565 4.1.4 porting bug reported by Bruce Becker in
4566 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4568 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4569 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4572 Merge changes from gnulib. This was prompted because the CVS
4573 snapshot didn't build on Solaris 7 due to strnlen problems.
4575 These changes need to be merged back into gnulib:
4576 * lib/hash.c: Include <stdbool.h> unconditionally.
4577 * m4/onceonly.m4 (m4_quote): New macro.
4578 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4579 Quote AC_FOREACH variable-expansions properly.
4580 The 2003-01-03 obstack.h change also needs merging.
4581 {end of changes requiring merging}
4583 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4584 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

4587 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
4588 New files, imported from gnulib.
4589 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
4592 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
4593 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
4596 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
4598 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
4599 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
4600 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
4601 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
4602 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
4603 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
4604 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
4605 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
4606 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
4607 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
4608 (jm_PREREQ_ARGMATCH): Remove.
4609 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
4610 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
4612 * src/system.h: Include <stdbool.h> unconditionally.
4614 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
4615 assuming at least C89 in the bitset code for some time now.
4617 2003-03-03 Akim Demaille <akim@epita.fr>
4621 2003-03-02 Akim Demaille <akim@epita.fr>
4623 * doc/bison.texinfo (Table of Symbols): Reactivate the
4624 documentation for %lex-param, and %parse-param.
4626 2003-03-02 Akim Demaille <akim@epita.fr>
4628 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4629 generate verbose error messages.
4630 Use the number of tokens as an upper bound in yytname, as it
4631 cannot be a non terminal.
4633 2003-03-02 Akim Demaille <akim@epita.fr>
4635 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4638 2003-03-02 Akim Demaille <akim@epita.fr>
4640 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4641 Use them to exercise yycheck overrun.
4642 Based on Andrew Suffield's grammar.
4644 2003-03-02 Akim Demaille <akim@epita.fr>
4646 Create tests/local.at for Bison generic testing macros.
4648 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4649 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4651 * tests/calc.at (AT_CHECK_CALC): Adjust.
4652 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
4653 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4654 * tests/local.at: here.
4655 (AT_COMPILE_CXX): Tags the tests using it as c++.
4656 Ignore the test if CXX is not functional.
4658 2003-03-01 Paul Eggert <eggert@twinsun.com>
4660 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
4661 not loc->end, since loc->end might contain garbage and this leads
4662 to undefined behavior on some platforms.
4663 (id_loc, token_start): Use (IF_LINTed) initial values that do not
4664 depend on *loc, so that the reader doesn't give the the false
4665 impression that *loc is initialized.
4666 (<INITIAL>"%%"): Do not bother setting code_start, since its value
4667 does not survive the return.
4669 2003-03-01 Akim Demaille <akim@epita.fr>
4671 * src/scan-gram.l (code_start): Always initialize it when entering
4672 into yylex, as SC_EPILOGUE is activated *before* the corresponding
4673 yylex invocation. An alternative would be making it static, but
4674 then it starts with the second %%'s beginning, instead of its end.
4676 2003-02-28 Paul Eggert <eggert@twinsun.com>
4678 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
4679 around a UnixWare 7.1.1 porting bug reported by John Hughes in
4680 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
4682 2003-02-26 Paul Eggert <eggert@twinsun.com>
4684 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
4685 Remove Sequent/Pyramid discussion (nobody uses them any more).
4686 Merge VMS and MS-DOS discussion; these ports may well be dead
4687 but let's keep mentioning them for now. Put <> around email
4688 addresses. Add copyright notice.
4690 2003-02-24 Paul Eggert <eggert@twinsun.com>
4692 * data/glr.c (yy_reduce_print): yylineno -> yylno,
4693 to avoid collision with flex use of yylineno.
4694 Problem reported by Bruce Lilly in
4695 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
4696 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4697 * data/yacc.c (yy_reduce_print): Likewise.
4699 * config/depcomp: Sync with Automake 1.7.3.
4701 2003-02-21 Akim Demaille <akim@epita.fr>
4703 * data/lalr1.cc: Use temporary variables instead of casts to
4704 change integer types.
4705 Suggested by Paul Eggert.
4707 2003-02-21 Akim Demaille <akim@epita.fr>
4709 * doc/bison.texinfo: Use "location" consistently to refer to @n,
4710 to avoid confusions with lalr1.cc's notion of Position.
4711 Suggested by Paul Eggert.
4713 2003-02-20 Akim Demaille <akim@epita.fr>
4715 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
4716 before initial_columns.
4717 (location.hh): Use consistent variable names when defining the
4719 Use "last" so that we subtract from Positions, not from unsigned.
4721 2003-02-20 Akim Demaille <akim@epita.fr>
4723 * data/lalr1.cc (position.hh): New subfile, including the extended
4724 and Doxygen'ed documentation of class Position.
4725 (location.hh): Use it.
4726 Document a` la Doxygen.
4727 With the help of Benoit Perrot.
4729 2003-02-20 Akim Demaille <akim@epita.fr>
4731 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
4733 Redefine AT_YYERROR_SEES_LOC_IF using it.
4734 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
4736 Don't use the location in yy::Parser::error_ and
4737 yy::Parser::print_ when not %locations.
4738 Activate more lalr1.cc tests.
4740 2003-02-19 Akim Demaille <akim@epita.fr>
4742 * data/lalr1.cc: When displaying a line number, be sure to make it
4745 2003-02-19 Akim Demaille <akim@epita.fr>
4747 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
4749 (YYABORT, YYACCEPT, YYERROR): New.
4750 * tests/calc.at: Renable the lalr1.cc test.
4752 2003-02-19 Akim Demaille <akim@epita.fr>
4754 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
4755 error recovery, mixing with/without pops and discarding of the
4758 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
4760 2003-02-17 Paul Eggert <eggert@twinsun.com>
4762 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
4763 * tests/testsuite.at (AT_COMPILE): Use them.
4764 This fixes the testsuite problem reported by Robert Lentz in
4765 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
4767 2003-02-12 Paul Eggert <eggert@twinsun.com>
4769 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
4770 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
4771 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
4772 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
4773 Check for malloc failure, for consistency with yacc.c.
4774 (yytname_size): Remove, for consistency with yacc.c.
4776 The bug still remains in data/lalr1.cc, as I didn't have time
4779 2003-02-06 Akim Demaille <akim@epita.fr>
4781 * configure.ac (GXX): Rename as...
4782 (CXX): this, to keep the original Autoconf semantics.
4784 * data/lalr1.cc: Fix b4_copyright invocations.
4785 If YYDEBUG is not defined, don't depend upon name_ being defined.
4786 (location.hh): Include string and iostream.
4787 (Position::filename): New member.
4788 (Position::Position ()): New.
4789 (operator<< (Position)): New.
4790 (operator- (Position, int)): New.
4791 (Location::first, Location::last): Rename as...
4792 (Location::begin, Location::end): these, to mock the conventional
4794 (operator<< (Location)): New.
4795 * tests/atlocal.in (CXX): New.
4796 * tests/testsuite.at (AT_COMPILE_CXX): New.
4797 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
4798 locations in a more synthetic way.
4799 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
4801 Adjust the C locations to match those from Emacs: first column is
4803 Change all the expected results.
4804 Conform to the GCS: simplify the locations when applicable.
4805 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
4806 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
4807 these CPP macros with the m4 macros new defined by...
4808 (AT_CHECK_PUSHDEFS): this, i.e.:
4809 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
4810 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
4812 (AT_CHECK_POPDEFS): Undefine them.
4813 (AT_CHECK_CALC_LALR1_CC): New.
4814 Use it for the first lalr1.cc test.
4816 2003-02-04 Akim Demaille <akim@epita.fr>
4818 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
4819 Location as is defined.
4821 2003-02-04 Akim Demaille <akim@epita.fr>
4823 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
4824 name_ being defined.
4826 2003-02-03 Paul Eggert <eggert@twinsun.com>
4828 * src/gram.h (start_symbol): Remove unused decl.
4830 Use more-consistent naming conventions for local vars.
4832 * src/derives.c (derives_compute): Change type of local var from
4834 * src/gram.c (grammar_rules_partial_print): Likewise.
4835 * src/print.c (print_core): Likewise.
4836 * src/reduce.c (reduce_grammar_tables): Likewise.
4838 * src/gram.c (grammar_dump): Change name of item_number *
4839 local var from r to rp.
4840 * src/nullable.c (nullable_compute): Likewise.
4842 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
4844 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
4845 for symbol or symbol_number var.
4846 * src/reader.c (grammar_start_symbol_set): Likewise.
4847 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
4849 * src/state.c (transitions_to): Likewise.
4850 * src/state.h: Likewise.
4851 * src/tables.c (symbol_number_to_vector_number): Likewise.
4853 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
4856 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
4859 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
4862 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
4863 Use str, not s, for char * var. Use ch, not c, for character var.
4864 Use size for size var.
4866 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
4868 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
4870 * src/uniqstr.h: Likewise.
4872 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
4873 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
4874 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
4875 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
4876 param to have same name as that of enum, so that we don't use
4877 "s" to stand for a non-state.
4879 2003-02-02 Akim Demaille <akim@epita.fr>
4881 * src/scan-skel.l: Scan more than one inert character per yylex
4884 2003-02-01 Paul Eggert <eggert@twinsun.com>
4888 * po/LINGUAS: Add ms.
4890 2003-01-30 Akim Demaille <akim@epita.fr>
4892 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
4894 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4896 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
4899 Changes in response to error report by S. Eken: GLR mode does not
4900 handle negative $ indices or $ indices in embedded rules correctly.
4901 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
4903 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
4904 (b4_rhs_location): Ditto.
4905 (yyfill): New function to copy from stack tree into array
4907 (yyuserAction): Modify to allow incremental move of semantic values
4908 to rhs array when in GLR mode.
4909 Define YYFILL to use in user-defined actions to fill semantic array
4911 Remove dummy use of yystack, as there is now a guaranteed use.
4912 (yydoAction): Modify to allow incremental move of semantic values
4913 to rhs array when in GLR mode.
4914 (yyresolveAction): Ditto.
4915 (yyglrShiftDefer): Update comment.
4916 (yyresolveStates): Use X == NULL for pointers, not !X.
4917 (yyglrReduce): Ditto.
4920 * tests/glr-regr1.at: Rename to ...
4921 * tests/glr-regression.at: Add new regression test for the problems
4922 described above (adapted from S. Eken).
4923 Update copyright notice.
4924 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
4925 * tests/Makefile.am: Ditto.
4927 2003-01-28 Paul Eggert <eggert@twinsun.com>
4929 * data/lalr1.cc: Do not use @output_header_name@ unless
4930 b4_defines_flag is set. This fixes two bugs reported by
4932 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
4933 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
4935 2003-01-21 Paul Eggert <eggert@twinsun.com>
4937 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
4938 we don't need to worry about yyerrlab1 being reported as an
4939 "unused label" by non-GCC C compilers. The downside is that if
4940 locations are used then a couple of statements are duplicated each
4941 time YYERROR is invoked, but the upside is that the warnings
4943 (yyerrlab1): Move code to YERROR.
4944 (yyerrlab2): Remove. Change uses back to yyerrlab1.
4945 This reverts some of the 2002-12-27 change.
4947 2003-01-17 Paul Eggert <eggert@twinsun.com>
4949 * src/output.c (symbol_printers_output): Fix typo that led
4950 to core dump. Problem reported by Antonio Rus in
4951 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
4953 2003-01-13 Akim Demaille <akim@epita.fr>,
4954 Quoc Peyrot <chojin@lrde.epita.fr>,
4955 Robert Anisko <anisko_r@lrde.epita.fr>
4957 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
4958 when the stacks contain one element, as the loop would otherwise
4959 free the last state, and then use the top state (the one we just
4960 popped). This means that the initial elements will not be freed
4961 explicitly, as is the case in yacc.c; it is not a problem, as
4962 these elements have fake values.
4964 2003-01-11 Paul Eggert <eggert@twinsun.com>
4966 * NEWS: %expect-violations are now just warnings, reverting
4967 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
4968 bootstrapping problem reported by Matthias Klose; see
4969 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
4970 * src/conflicts.c (conflicts_print): Likewise.
4971 * tests/conflicts.at (%expect not enough, %expect too much,
4972 %expect with reduce conflicts): Likewise.
4973 * doc/bison.texinfo (Expect Decl): Document this. Also mention
4974 that the warning is enabled if the number of conflicts changes
4975 (not necessarily increases).
4977 * src/getargs.c (version): Update copyright year.
4979 2003-01-09 Akim Demaille <akim@epita.fr>
4981 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
4983 2003-01-08 Paul Eggert <eggert@twinsun.com>
4985 * Makefile.maint (WGETFLAGS):
4986 New macro, containing "-C off" to disable proxy caches.
4987 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
4988 (rel-check): Use $(WGET) instead of wget.
4990 2003-01-06 Paul Eggert <eggert@twinsun.com>
4992 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
4993 the GLR paper of Scott, Johnstone and Hussain.
4995 2003-01-04 Paul Eggert <eggert@twinsun.com>
4997 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
4998 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
4999 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5000 (EXTRA_LIBRARIES): New var, for liby.a.
5001 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5002 (EXTRA_SCRIPTS): New var, for yacc.
5004 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5005 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5006 Problem reported by Nelson H. F. Beebe.
5008 2003-01-03 Paul Eggert <eggert@twinsun.com>
5010 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5011 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5012 when compiling Bison 1.875's `bitset bset = obstack_alloc
5013 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5015 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5016 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5017 grow to a huge size with typical invocation.
5019 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5020 Use the pattern recommended by Autoconf 2.57, except also protect
5021 against double-definition.
5022 * src/system.h: Likewise.
5023 Portability issues reported by Nelson H. F. Beebe.
5025 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5026 All uses changed. Provide a definition in both C and C++.
5027 (yytrue, yyfalse): Define even if defined (__cplusplus).
5029 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5030 Reported by Nelson H. F. Beebe.
5032 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5034 2003-01-02 Paul Eggert <eggert@twinsun.com>
5036 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5037 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5038 Bug reported by Nelson H. F. Beebe.
5040 2003-01-01 Paul Eggert <eggert@twinsun.com>
5044 2002-12-30 Paul Eggert <eggert@twinsun.com>
5046 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5048 (<INITIAL>","): Here. This causes stray "," to be treated
5051 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5052 last brace in braced code when not in Yacc mode, for compatibility
5053 with Bison 1.35. This resurrects the 2001-12-15 patch to
5056 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5057 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5059 2002-12-28 Paul Eggert <eggert@twinsun.com>
5061 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5062 that of SYM's type. This fixes Debian bug 168069, reported by
5065 2002-12-28 Paul Eggert <eggert@twinsun.com>
5069 Switch back to the Yacc style of conflict reports, undoing some
5070 of the 2002-07-30 change.
5071 * doc/bison.texinfo (Understanding): Use Yacc style for
5072 conflict reports. Also, use new way of locating rules.
5073 * src/conflicts.c (conflict_report):
5074 Renamed from conflict_report_yacc, removing the old
5075 'conflict_report'. Translate the entire conflict report at once,
5076 so that we don't assume that "," has the same interpretation in
5078 (conflicts_output): Use Yacc-style conflict report for each state,
5079 instead of our more-complicated style.
5080 (conflicts_print): Use Yacc-style conflict report, except print
5081 the input file name when not emulating Yacc.
5082 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5083 Conflicted Reduction, %expect not enough, %expect too much,
5084 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5085 * tests/existing.at (GNU Cim Grammar): Likewise.
5086 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5088 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5089 fatal): Don't invoke fflush; it's not needed and it might even be
5090 harmful for stdout, as stdout might not be open.
5091 * src/reduce.c (reduce_print): Likewise.
5093 2002-12-27 Paul Eggert <eggert@twinsun.com>
5095 Fix a bug where error locations were not being recorded correctly.
5096 This problem was originally reported by Paul Hilfinger in
5097 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5099 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5100 top of the location stack's error locations.
5101 (yyerrlab): Set it. When discarding a token, push its location
5102 onto yylerrsp so that we don't lose track of the error's end.
5103 (yyerrlab1): Now is only the target of YYERROR, so that we can
5104 properly record the location of the action that failed. For GCC
5105 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5106 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5107 (yyerrlab2): New label, which yyerrlab now falls through to.
5108 Compute the error's location by applying YYLLOC_DEFAULT to
5109 the locations of all the symbols that went into the error.
5110 * doc/bison.texinfo (Location Default Action): Mention that
5111 YYLLOC_DEFAULT is also invoked for syntax errors.
5112 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5113 Error locations include the locations of all the tokens that were
5114 discarded, not just the last token.
5116 2002-12-26 Paul Eggert <eggert@twinsun.com>
5118 * src/files.c: Include quote.h.
5119 (compute_output_file_names): Warn if we detect conflicting
5120 outputs to the same file. This should catch the misunderstanding
5121 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5123 * src/conflicts.c (conflicts_print): If the user specifies
5124 "%expect N", report an error if there are any reduce/reduce
5125 conflicts. This is what the manual says should happen.
5126 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5127 * tests/conflicts.at (%expect with reduce conflicts): New test.
5129 Don't use m4_include on relative file names, as it doesn't work as
5130 desired if there happens to be a file with that name under ".".
5132 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5133 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5134 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5135 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5136 * src/output.c (output_skeleton): Use full path names when
5137 specifying a file to include; don't rely on include path, as
5138 it's unreliable when the working file contains a file with
5141 2002-12-25 Paul Eggert <eggert@twinsun.com>
5143 Remove obsolete references to bison.simple and bison.hairy.
5144 Problem mentioned by Aubin Mahe in
5145 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5146 * data/glr.c: Comment fix.
5147 * doc/bison.1: Remove references. Also, mention "yacc".
5149 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5152 * src/parse-gram.y (declaration): Use enum "report_states" rather
5153 than its numeric value 1.
5155 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5156 opening a new one. This fixes Debian bug 165349, reported by
5159 2002-12-24 Paul Eggert <eggert@twinsun.com>
5163 * Makefile.maint (cvs-update): Don't assume that the shell
5164 supports $(...), as Solaris sh doesn't.
5166 * src/parse-gram.y (lloc_default): Remove test for empty
5167 nonterminals at the end, since it didn't change the result.
5169 2002-12-24 Paul Eggert <eggert@twinsun.com>
5171 If the user does not define YYSTYPE as a macro, Bison now declares it
5172 using typedef instead of defining it as a macro. POSIX requires this.
5173 For consistency, YYLTYPE is also declared instead of defined.
5175 %union directives can now have a tag before the `{', e.g., the
5176 directive `%union foo {...}' now generates the C code
5177 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5178 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5179 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5180 instead of `yyltype'.
5182 `yystype' and `yyltype' are now obsolescent macros instead of being
5183 typedefs or tags; they are no longer documented and will be
5184 withdrawn in a future release.
5186 * data/glr.c (b4_location_type): Remove.
5187 (YYSTYPE): Renamed from yystype.
5188 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5189 (struct YYLTYPE): Renamed from struct yyltype.
5190 (YYLTYPE): Renamed from yyltype.
5191 (yyltype, yystype): New (and obsolescent) macros,
5192 for backward compatibility.
5193 * data/yacc.c: Likewise.
5195 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5196 does not specify a union tag. This is for compatibility with
5199 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5200 const *, since it is now modified by stripping surrounding { }.
5201 (current_braced_code): Remove.
5202 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5203 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5204 trailing " {...}". Now of type <chars>.
5205 (grammar_declaration): Adjust to bundled tokens.
5206 (code_content): Remove; stripping is now done by add_param.
5207 (print_token_value): Print contents of bundled tokens.
5208 (token_name): New function.
5210 * src/reader.h (braced_code, current_braced_code): Remove.
5211 (token_name): New decl.
5213 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5214 token_type, not braced_code code_kind. All uses changed.
5215 (SC_PRE_CODE): New state, for scanning after a keyword that
5216 has (or usually has) an immediately-following braced code.
5217 (token_type): New local var, to keep track of which token type
5218 to return when scanning braced code.
5219 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5220 <INITIAL>"%parse-param", <INITIAL>"%printer",
5221 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5222 instead of returning a token type immediately.
5223 (<INITIAL>"{"): Set token type.
5224 (<SC_BRACED_CODE>"}"): Use it.
5225 (handle_action_dollar, handle_action_at): Now returns bool
5226 indicating success. Fail if ! current_rule; this prevents a core dump.
5227 (handle_symbol_code_dollar, handle_symbol_code_at):
5228 Remove; merge body into caller.
5229 (handle_dollar, handle_at): Complain in invalid contexts.
5231 * NEWS, doc/bison.texinfo: Document the above.
5232 * NEWS: Fix years and program names in copyright notice.
5234 2002-12-17 Paul Eggert <eggert@twinsun.com>
5236 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5237 Reporting, Table of Symbols): Omit mentions of %lex-param and
5238 %parse-param from the documentation for now.
5240 2002-12-15 Paul Eggert <eggert@twinsun.com>
5242 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5243 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5244 lookahead symbol, and which sets yychar in parser actions) and it
5245 disagreed with the Bison documentation. Bug
5246 reported by Andrew Walrond.
5248 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5249 as the caller now does that.
5250 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5251 (YYEMPTY): Parenthesize right hand side, since others use it.
5252 (yyparse): Don't assume that our generated code is the only code
5255 2002-12-13 Paul Eggert <eggert@twinsun.com>
5259 POSIX requires a "yacc" command.
5260 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
5261 (MOSTLYCLEANFILES): Add yacc.
5263 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
5264 as an alias for bison y.
5266 * po/LINGUAS: Add da.
5268 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
5269 problem with latest <getopt.h>.
5270 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
5272 * doc/fdl.texi: Upgrade to 1.2.
5273 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
5274 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
5275 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
5277 * config/install-sh: Sync with autotools.
5279 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5280 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5281 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5282 locations are requested.
5283 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5284 locations are requested.
5286 2002-12-12 Paul Eggert <eggert@twinsun.com>
5288 Remove unportable casts and storage allocation tricks.
5289 While we're at it, remove almost all casts, since they
5290 usually aren't needed and are a sign of trouble.
5292 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5294 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5295 the pointer DSET returned by malloc; this isn't portable.
5296 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5297 Similarly for DERIVES.
5298 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5299 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5300 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5302 * src/derives.c (derives_compute): Do not bother invoking
5303 int_of_rule_number, since rule numbers are integers.
5305 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
5306 rather than XMALLOC (char, N).
5308 * src/files.c (filename_split): Rewrite to avoid cast.
5310 * src/gram.h (symbol_number_as_item_number,
5311 item_number_as_symbol_number, rule_number_as_item_number,

5316 symbol_number_to_vector_number): Likewise.
5318 * src/gram.h (int_of_rule_number): Remove; no longer used.
5320 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5321 since the resulting storage is always stored into.
5323 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5326 * src/muscle_tab.c (muscle_m4_output):
5327 Now inline. Return bool, not int.
5328 * src/state.c (state_compare): Likewise.

5338 symbol_check_alias_consistency_processor, symbol_pack_processor,
5339 symbol_translation_processor, hash_symbol_comparator,
5340 hash_symbol_hasher): Likewise.
5341 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5342 * src/muscle_tab.c (muscles_m4_output):
5343 Use new functions instead of casting old functions unportably.
5344 * src/state.c (state_hash_new): Likewise.
5345 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5346 symbols_token_translations_init):
5348 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5350 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5351 var instead of casting to long, to avoid casts.
5352 (prepare_states): Use MALLOC rather than alloca, so that we don't
5353 have to worry about alloca.
5354 * src/state.c (state_hash_lookup): Likewise.
5356 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5357 local var instead of casting to unsigned char, to avoid casts.
5359 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
5360 STATE_ALLOC): Remove.
5361 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5362 rather than calloc, and use offsetof to avoid allocating slightly
5364 (state_new): Initialize all members.
5366 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5368 * src/symtab.c (symbol_free): Remove; unused.
5369 (symbol_get): Remove cast in lhs of assignment.
5370 (symbols_do): Now static. Accept generic arguments, not
5371 hashing-related ones.
5373 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5374 (symbol_processor): Remove.
5375 (symbols_do): Remove decl; now static.
5377 * src/system.h (alloca): Remove; decl no longer needed.
5378 (<stddef.h>): Include, for offsetof.
5379 (<inttypes.>, <stdint.h>): Include if available.
5380 (uintptr_t): New type, if system lacks it.
5381 (CALLOC, MALLOC, REALLOC): New macros.
5382 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5385 * src/tables.c (table_size): Now int, to pacify GCC.
5386 (table_grow, table_ninf_remap): Use signed table size.
5387 (save_row): Don't bother initializing locals when not needed.
5388 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5389 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5391 * src/vcg.h: Correct misspellings.
5393 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5396 * src/getargs.c (getargs): Don't assume EOF == -1.
5398 2002-12-09 Paul Eggert <eggert@twinsun.com>
5400 Change identifier spellings to avoid collisions with names
5401 that are reserved by POSIX.
5403 Don't use names ending in _t, since POSIX reserves them.
5404 For consistency, remove _e and _s endings -- they're weren't
5405 needed to remove ambiguity. All uses changed.
5406 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5407 turn was just renamed from struniq_t.
5408 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5409 which in turn was just renamed from struniq_processor_t.
5410 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
5411 in turn was renamed from hash_compare_struniq_t.

5480 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
5481 value_t_as_yystype -> value_as_yystype.
5483 Don't include <errno.h> in the mainstream code, since it
5484 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5485 * lib/get-errno.c, lib/get-errno.h: New files.
5486 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5488 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

5496 (TAB_EXT): Renamed from EXT_TAB.
5497 (OUTPUT_EXT): Renamed from EXT_OUTPUT.

5501 likewise for "STRUNIQ" and "UNIQSTR".
5502 * src/uniqstr.c: Renamed from src/struniq.c.
5503 * src/uniqstr.h: Renamed from src/struniq.h.
5504 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

5525 (BASE_MAXIMUM): Renamed from BASE_MAX.
5526 (BASE_MINIMUM): Renamed from BASE_MIN.
5527 (ACTION_MAX): Remove; unused.
5528 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
5529 Unnecessary casts removed from above defines.
5532 Fix misspelling in names.
5533 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
5534 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
5538 * lib/timevar.c (timevar_report): Renamed from time_report,
5539 for consistency with other names.
5540 * lib/timevar.h (timevar_report): New decl.
5541 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5544 Sort include-file uses.
5546 Reorder all include files under src to be in the order "system.h".
5547 then the ../lib include files in angle brackets (alphabetized),
5548 then the . include files in double-quotes (alphabetized). Fix
5549 dependency breakages encountered in this process, as follows:
5550 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5551 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5552 * src/state.h: Include "symtab.h".
5554 2002-12-08 Paul Eggert <eggert@twinsun.com>
5556 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5557 since this causes problems when __file__ contains character
5558 sequences like "@" that are treated specially by src/scan-skel.l.
5559 Instead, just use the file's basename. This fixes the bug
5560 reported by Martin Mokrejs in
5561 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5563 2002-12-06 Paul Eggert <eggert@twinsun.com>
5565 Add support for rules that do not have trailing semicolons, as
5566 POSIX requires. Improve the quality of locations in Bison
5569 * src/location.c: Include <quotearg.h>.
5570 (empty_location): Now const.
5571 (location_print): New function. Follow the recommendation of the
5572 GNU Coding Standards for locations that span file boundaries.
5573 * src/location.h: Do not include <quotearg.h>; no longer needed.
5574 (boundary): New type.
5575 (location_t): Use it. This allows locations to span file boundaries.
5576 All member uses changed: file -> start.file or end.file (as needed),
5577 first_line -> start.line, first_column -> start.column,
5578 last_line -> end.line, last_column -> end.column.
5579 (equal_boundaries): New function.
5580 (LOCATION_RESET, LOCATION_STEP): Remove.
5581 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5582 (empty_location): Now const.
5583 (location_print): New decl.
5584 * src/parse-gram.y (lloc_default): New function, which handles
5585 empty locations more accurately.
5586 (YYLLOC_DEFAULT): Use it.
5587 (%token COLON): Remove.
5588 (%token ID_COLON): New token.
5590 (declarations, rules): Remove trailing semicolon.
5591 (declaration, rules_or_grammar_declaration):
5592 Allow empty (";") declaration.
5593 (symbol_def): Remove empty actions; no longer needed.
5594 (rules_or_grammar_declaration): Remove trailing semicolon.
5595 (semi_colon.opt): Remove.
5596 * src/reader.h: Include location.h.
5597 (scanner_cursor): New decl.
5598 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
5600 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5602 (STEP): Remove. No longer needed, now that adjust_location does
5603 the work. All uses removed.
5604 (scanner_cursor): New var.
5605 (adjust_location): Renamed from extend_location. It now sets
5606 *loc and adjusts the scanner cursor. All uses changed.
5607 Don't bother testing for CR.
5608 (handle_syncline): Remove location arg; now updates scanner cursor.
5609 All callers changed.
5610 (unexpected_end_of_file): Now accepts start boundary of token or
5611 comment, not location. All callers changed. Update scanner cursor,
5613 (SC_AFTER_IDENTIFIER): New state.
5614 (context_state): Renamed from c_context. All uses changed.
5615 (id_loc, code_start, token_start): New local vars.
5616 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5617 processing of Yacc white space and equivalents here.
5618 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5619 instead of returning ID immediately, since we need to search for
5621 (<INITIAL>"'", "\""): Save token_start.
5622 (<INITIAL>"%{", "{", "%%"): Save code_start.
5623 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5624 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5625 BEGIN context_state at end, not INITIAL.
5626 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5627 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5628 Return correct token start.
5629 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5630 the start of a character, string or multiline comment is found.
5631 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5632 Reduction): Adjust reported locations to match the more-precise
5633 results now expected.
5634 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5635 * tests/reduce.at (Useless Rules, Reduced Automaton,
5636 Underivable Rules): Likewise.
5637 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5638 or "|"' now that so many other tokens are allowed by the new grammar.
5640 * src/complain.h (current_file): Remove duplicate decl;
5641 current_file is now owned by files.h.
5642 * src/complain.c, src/scan-gram.l: Include files.h.
5644 2002-12-06 Paul Eggert <eggert@twinsun.com>
5646 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5647 promotes to int; it might be unsigned int.
5648 * data/yacc.c (yy_reduce_print): Likewise.
5650 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5651 be #defined in the prologue, not in the Bison declarations.
5652 This fixes Debian Bug 102878, reported by Shaul Karl.
5654 2002-12-02 Paul Eggert <eggert@twinsun.com>
5656 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
5657 * lib/strtoul.c: New file, from gnulib.
5658 This fixes a porting bug reported by Peter Klein in
5659 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
5661 2002-11-30 Paul Eggert <eggert@twinsun.com>
5663 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
5664 and put only a forward declaration in the prologue. This is for
5665 consistency with the other scanner helper functions.
5667 Type clashes now generate warnings, not errors, since it
5668 appears that POSIX may allow some grammars with type clashes.
5669 * src/reader.c (grammar_current_rule_check): Warn about
5670 type clashes instead of complaining.
5671 * tests/input.at (Type Clashes): Expect warnings, not complaints.
5673 Add Yacc library, since POSIX requires it.
5674 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
5675 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
5676 * lib/main.c, lib/yyerror.c: New files.
5678 gram_error can be static; it need not be extern.
5679 * src/reader.h (gram_error): Remove decl.
5680 * src/parse-gram.y (gram_error): Now static. Add static decl.
5681 (print_token_value): Omit parameter names from forward decl,
5684 2002-11-29 Paul Eggert <eggert@twinsun.com>
5686 * doc/bison.texinfo: Emphasize that yylex and yyerror must
5687 be declared before being used. E.g., one should typically
5688 declare them in the prologue. Use GNU coding style in examples.
5689 Put "const" consistently after the type it modifies. Mention
5690 that C99 supports "inline". Mention that yyerror traditionally
5693 %parse-param and %lex-param now take just one argument, the
5694 declaration; the argument name is deduced from the declaration.
5696 * doc/bison.texinfo (Parser Function, Pure Calling, Error
5697 Reporting, Table of Symbols): Document this.
5698 * src/parse-gram.y (add_param): New function.
5700 (declaration): Implement new rule for %parse-param and %lex-param.
5701 * src/scan-gram.l: "," now elicits a warning, rather than being
5702 a token; this is more compatible with byacc.
5703 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
5705 2002-11-27 Paul Eggert <eggert@twinsun.com>
5707 Rename identifiers to avoid real and potential collisions.
5709 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
5710 to avoid collision with lex macro described by Bruce Lilly in
5711 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5712 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
5713 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
5714 * src/parse-gram.y (print_token_value): Renamed from yyprint.
5716 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
5717 The name "yycontrol" violates the name space rules, and this stuff
5718 wasn't being used anyway.
5719 (input): Remove action; this stuff wasn't being used.
5720 (gram_error): Rename local variable yylloc -> loc.
5721 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
5722 (YY_DECL): Don't use "yy" at start of local variables.
5723 All uses changed, e.g., yylloc -> loc.
5724 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
5725 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
5726 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
5727 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
5729 * src/parse-gram.y (gram_error): loc is now const *.
5730 * src/reader.h (gram_error): Likewise.
5732 2002-11-24 Paul Eggert <eggert@twinsun.com>
5736 * tests/actions.at (Actions after errors): Use an output format
5737 more similar to that of the Printers and Destructors test.
5738 Test the position of the ';' token too.
5739 (Printers and Destructors): Likewise.
5740 (Printers and Destructors: %glr-parser): Remove for now, to avoid
5741 unnecessarily alarming people when the test fails.
5743 * data/yacc.c (yyerrlab1): Move this label down, so that the
5744 parser does not discard the lookahead token if the user code
5745 invokes YYERROR. This change is required for POSIX conformance.
5747 * lib/error.c: Sync with gnulib.
5749 2002-11-22 Paul Eggert <eggert@twinsun.com>
5751 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
5752 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
5753 * lib/xmalloc.c: Likewise.
5755 2002-11-20 Paul Eggert <eggert@twinsun.com>
5757 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
5759 2002-11-20 Paul Eggert <eggert@twinsun.com>
5761 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
5762 should use `if (! x) abort ();' rather than `assert (x);', and
5763 anyway it's one less thing to worry about configuring.
5765 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
5766 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
5767 and replace all instances of assert with abort.
5768 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5769 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
5771 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
5772 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
5773 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
5774 hash_find_entry, hash_rehash, hash_insert): Likewise.
5775 * src/conflicts.c (resolve_sr_conflict): Likewise.
5776 * src/lalr.c (set_goto_map, map_goto): Likewise.
5777 * src/nullable.c (nullable_compute): Likewise.

5781 state_reduction_find): Likewise.
5782 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
5783 symbol_pack): Likewise.
5784 * src/tables.c (conflict_row, pack_vector): Likewise.
5785 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5786 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5787 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
5788 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
5790 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
5791 (ARGMATCH_CONSTRAINT): New macro.
5792 (ARGMATCH_ASSERT): Use it.
5794 * src/system.h (verify): New macro.
5795 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
5797 * src/tables.c (tables_generate): Likewise.
5799 * src/struniq.c (struniq_assert): Now returns void, and aborts
5800 if the assertion is false.
5801 (struniq_assert_p): Remove.
5802 * src/struniq.h: Likewise.
5804 2002-11-18 Paul Eggert <eggert@twinsun.com>
5806 * data/glr.c (yygetLRActions): Replace `yyindex' with
5807 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
5808 This fixes the regression with Sun ONE Studio 7 cc that I reported in
5809 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
5811 2002-11-18 Akim Demaille <akim@epita.fr>
5813 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
5815 From Tim Van Holder.
5817 2002-11-17 Paul Eggert <eggert@twinsun.com>
5819 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
5820 to "SyntaxError" for consistency with my 2002-11-15 change.
5822 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
5823 not define to {}, since this breaks the common use of `YYDPRINTF
5824 ((...));' if a single statement is desired (e.g. before `else').
5825 Work around GCC warnings by surrounding corresponding calls with
5827 (yyhasResolvedValue): Remove unused function.
5828 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
5830 (yyreportSyntaxError): Renamed from yyreportParseError.
5831 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
5833 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
5834 extern when possible. Remove unused initializations.
5836 2002-11-16 Akim Demaille <akim@epita.fr>
5838 Augment the similarity between GLR and LALR traces.
5840 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
5841 (YY_REDUCE_PRINT): New.
5842 (yyparse): Use them.
5843 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
5845 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
5846 state reached after the reduction/recovery, since...
5847 (yyparse, yyprocessOneStack): Report the state we are entering in.
5849 2002-11-16 Akim Demaille <akim@epita.fr>
5851 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
5852 Add support for --trace=skeleton.
5853 * src/scan-skel.l: %option debug.
5854 Scan strings of non-@ or \n instead of character by character.
5855 (scan_skel): Handle trace_skeleton.
5857 (@output_parser_name@, @output_header_name@): ``Restore'' their
5858 support (used to be M4 macros).
5859 * data/yacc.c: Quote larger chunks, a la glr.c.
5860 * data/lalr1.cc: Likewise.
5861 The header guards are no longer available, so use some other
5862 string than `YYLSP_NEEDED'.
5864 2002-11-16 Akim Demaille <akim@epita.fr>
5866 Make the ``Printers and Destructors'' test more verbose, taking
5867 `yacc.c''s behavior as (possibly wrong) reference.
5869 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
5870 instead of fprint on stdout.
5871 Set and report the last_line of the symbols.
5872 Consistently display values and locations.
5874 2002-11-16 Paul Eggert <eggert@twinsun.com>
5876 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
5878 2002-11-15 Paul Eggert <eggert@twinsun.com>
5880 * tests/actions.at (Actions after errors): New test case.
5882 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
5883 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
5884 tests/action.at, tests/calc.at, tests/conflicts.at,
5885 tests/cxx-type.at, tests/regression.at:
5886 "parse error" -> "syntax error" for POSIX compatibility.
5887 "parsing stack overflow..." -> "parser stack overflow" so
5888 that code matches Bison documentation.
5890 2002-11-15 Akim Demaille <akim@epita.fr>
5892 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
5893 take two BRACED_CODE, not two string_content.
5894 Free the scanner's obstack when we are done.
5895 (code_content): New.
5896 * tests/calc.at: Adjust.
5897 * doc/bison.texinfo: Adjust.
5898 Also, make sure to include the `,' for these declarations.
5900 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
5902 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
5903 definition; avoids potential autoreconf problems.
5905 2002-11-15 Akim Demaille <akim@epita.fr>
5907 Always check the value returned by yyparse.
5909 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
5910 returned by yyparse.
5911 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
5913 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
5914 returned by yyparse.
5916 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5918 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
5921 2002-11-14 Paul Eggert <eggert@twinsun.com>
5923 * src/output.c (output_skeleton): Call xfopen instead of
5924 duplicating xfopen's body.
5926 Fix bugs reported by Nelson H. F. Beebe in
5927 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
5929 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
5930 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
5931 Group compiler. Instead, use "$CC -E bar.c". Include the .h
5932 file twice in the grammar, as an extra check.
5934 * tests/input.at (Torturing the Scanner): Surround the
5935 backslash-newline tests with "#if 0", to make it less likely that
5936 we'll run into compiler bugs. Bring back solitary \ inside
5937 comment, but add a closing comment to work around HP C bug. Don't
5938 test backslash-newline in C character constant.
5940 2002-11-14 Akim Demaille <akim@epita.fr>
5942 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
5943 status of the compiler.
5944 Calling `exit 1' is no longer needed.
5945 Reported by Nelson H. F. Beebe.
5947 2002-11-14 Akim Demaille <akim@epita.fr>
5949 * tests/atlocal.in (CPPFLAGS): We have config.h.
5950 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
5952 * tests/actions.at, tests/calc.at, tests/conflicts.at,
5953 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
5954 * tests/regression.at, tests/torture.at: Use them for all the
5955 grammars that are to be compiled.
5956 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
5957 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
5958 * doc/bison.texinfo (GLR Parsers): Document `inline'.
5960 2002-11-14 Akim Demaille <akim@epita.fr>
5962 * doc/bison.texinfo: Various formatting changes (alignments in
5963 samples, additional @group/@end group, GCS in samples.
5964 Use @deffn instead of simple @table to define the directives,
5965 macros, variables etc.
5967 2002-11-13 Paul Eggert <eggert@twinsun.com>
5969 Fix some bugs reported by Albert Chin-A-Young in
5970 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
5972 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
5973 -o c"; the HP C compiler chatters during compilation.
5974 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
5975 * tests/headers.at (export YYLTYPE): Likewise.
5977 * tests/input.at (Torturing the Scanner): Remove lines containing
5978 solitary backslashes, as they tickle a bug in the HP C compiler.
5980 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
5981 comments, since they're not portable. Use GNU coding style.
5983 2002-11-13 Akim Demaille <akim@epita.fr>
5985 * data/yacc.c: Leave bigger chunks of quoted text.
5986 (YYDSYMPRINTF): New.
5987 Use it to report symbol activities.
5988 * data/glr.c (YYDSYMPRINTF): New.
5991 2002-11-12 Paul Eggert <eggert@twinsun.com>
5995 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
5996 (yyglrReduce): Return yyok, not 0.
5997 This should avoid the enumerated-type warnings reported
5998 by Nelson H. F. Beebe in
5999 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6001 * lib/bbitset.h (BITSET_INLINE): Remove.
6002 * lib/bitset.h [! BITSET_INLINE]: Remove.
6003 (bitset_set, bitset_reset, bitset_test): Rename local vars
6004 to avoid shadowing warnings by GCC.
6006 * data/glr.c (inline): Remove #define. It's the user's
6007 responsibility to #define it away, just like 'const'.
6008 This fixes one of the bugs reported by Nelson H. F. Beebe in
6009 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6011 * Makefile.maint (po-check): Scan .l and .y files instead of the
6012 .c and the .h files that they generate. This fixes the bug
6013 reported by Tim Van Holder in:
6014 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6015 Look for N_ as well as for _. Try to avoid matching #define for
6017 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6018 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
6019 * src/scan-gram.l: Revamp regular expressions so that " and '
6020 do not confuse xgettext.
6022 * src/struniq.h (struniq_new): Do not declare the return type
6023 to be 'const'; this violates the C standard.
6024 * src/struniq.c (struniq_new): Likewise.
6026 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6028 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
6029 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
6032 2002-11-12 Akim Demaille <akim@epita.fr>
6034 * Makefile.maint: Sync with Autoconf:
6035 (local_updates): New.
6037 2002-11-12 Akim Demaille <akim@epita.fr>
6039 * po/POTFILES.in (src/lalr.c, src/state.c): Remove

6046 2002-11-12 Akim Demaille <akim@epita.fr>
6048 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
6051 2002-11-12 Akim Demaille <akim@epita.fr>
6053 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
6054 Use it to test the GLR parser.
6056 2002-11-12 Akim Demaille <akim@epita.fr>

6172 Revamp to fix many (but not all) of the C- and M4-related quoting
6173 problems. Among other things, this fixes the Bison bug reported
6174 by Jan Hubicka when processing the Bash grammar; see:
6175 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6177 Use new @ escapes consistently. Represent brackets with @{ and @}
6178 rather than @<:@ and @:>@, since this works a bit better with dumb
6179 editors like vi. Represent @ with @@, since @ is now consistently
6180 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6181 __ofile__, to avoid unexpected expansions. Similarly, use @output
6182 rather than #output.
6184 * data/c.m4 (b4_copyright): Omit file name from comment, since
6185 the file name could contain "*/".
6186 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6187 be quoted. All uses changed.
6189 * data/glr.c: Use new @ escapes consistently.
6190 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6191 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6192 Remove, since they couldn't handle arbitrary characters in file
6194 * data/lalr1.cc: Likewise.
6195 * data/yacc.c: Likewise.
6197 * src/files.c (output_infix): Remove; all uses removed.
6198 * src/files.h: Likewise.
6200 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6201 mishandled funny characters in file names, and anyway it isn't
6203 * data/yacc.c: Likewise.
6204 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6206 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6207 * data/yacc.c: Likewise.
6209 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6211 (muscle_init): Quote filename as a C string.
6212 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6213 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6214 * src/output.c (escaped_file_name_output): New function.
6215 (prepare_symbols): Quote tokens for M4.
6216 (prepare): Don't insert output_infix, output_prefix,
6217 output_parser_name, output_header_name; this is now down by scan-skel.
6218 Insert skeleton as a C string.
6220 * src/output.c (user_actions_output, symbol_destructors_output,
6221 symbol_printers_output): Quote filenames for C and M4.
6222 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6224 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6225 escapes other than \\ and \'; this simplifies the code.
6226 (<SC_STRING>): Likewise, for \\ and \".
6227 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6228 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6229 Use new escapes @{ and @} for [ and ].
6231 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6232 them with auto vars.
6233 Switch to new escape scheme, where @ is the escape character uniformly.
6234 Abort if a stray escape character is found. Avoid unbounded input
6235 buffer when parsing non-escaped text.
6237 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6238 __oline__, #output, $@, and @{ do not have unintended meanings.
6240 2002-11-09 Paul Eggert <eggert@twinsun.com>
6242 Fix the test failure due to GCC warnings described in
6243 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6244 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6245 evaluate to 0 if it's impossible for NINF to be in the respective
6247 (yygetLRActions, yyrecoverParseError): Use them.
6249 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6250 counted in the token inserted at end of file. Now takes
6251 location_t *, not location_t, so that the location can be
6252 adjusted. All uses changed.
6254 * tests/regression.at (Invalid inputs): Adjust wording in
6255 diagnostic to match the new behavior.
6257 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6258 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6259 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6260 abort ();'. This reduces the runtime of the "Many lookaheads"
6261 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6264 2002-11-07 Paul Eggert <eggert@twinsun.com>
6266 * src/parse-gram.y (CHARACTER): Remove unused token.
6269 * src/scan-gram.l: Remove stack option. We no longer use the
6270 stack, since the stack was never deeper than 1; instead, use the
6271 new auto var c_context to record the stacked value.
6273 Remove nounput option. At an unexpected end of file, we now unput
6274 the minimal input necessary to end cleanly; this simplifies the
6277 Avoid unbounded token sizes where this is easy.
6279 (unexpected_end_of_file): New function.
6280 Use it to systematize the error message on unexpected EOF.
6281 (last-string): Now auto, not static.
6282 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6283 (scanner_last_string_free): Remove; not used.

6285 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6286 not the (never otherwised-used) CHARACTER.
6288 2002-11-07 Akim Demaille <akim@epita.fr>
6290 Let yyerror always receive the msg as last argument, so that
6291 yyerror can be variadic.

6308 * src/output.c (symbol_printers_output)
6309 (symbol_destructors_output): Quote the file name.

6338 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6340 * src/tables.c (matching_state): Don't allow states to match if
6341 either has GLR conflict entries.
6343 2002-11-05 Paul Eggert <eggert@twinsun.com>
6345 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6346 "integer out of range" rather than "invalid value".
6347 * tests/input.at (Invalid $n, Invalid @n): Change expected wording

6354 Initialize to zero if the compiler is being picky.
6355 (INITIAL): Clear braces_level instead of incrementing it.

6357 as POSIX 1003.1-2001 requires.
6358 * src/system.h (IF_LINT): New macro, taken from coreutils.
6359 * configure.ac: Define "lint" if --enable-gcc-warnings.
6361 2002-11-05 Akim Demaille <akim@epita.fr>
6363 * src/scan-gram.l: When it starts with `%', complain about the

6508 * src/output.c (prepare_symbols): When printing token names,
6509 escape "[" as "@<:@" and likewise for "]".
6511 * src/system.h (errno): Remove declaration, as we are now
6512 assuming C89 or better, and C89 guarantees errno.

6523 and ferror. xfclose now checks ferror.
6525 * data/glr.c (YYLEFTMOST_STATE): Remove.

6527 our continuing battles with bogus warnings about initializers.

6544 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6545 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6546 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6547 Don't assume strdup exists; POSIX says its an XSI extension.
6548 Check for buffer overflow on input.
6550 2002-10-24 Akim Demaille <akim@epita.fr>
6552 * src/output.c (output_skeleton): Don't disable M4sugar comments
6553 too soon: it results in comments being expanded.
6554 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6557 2002-10-24 Akim Demaille <akim@epita.fr>
6559 * data/yacc.c (m4_int_type): New.
6560 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6561 char' as only yacc.c wants K&R portability.
6562 * data/glr.c (yysigned_char): Remove.
6563 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6564 Reported by Quoc Peyrot.
6566 2002-10-23 Paul Eggert <eggert@twinsun.com>
6568 * src/main.c (main): With --trace=time, report times even if a
6569 non-fatal error occurs. Formerly, the times were reported in some
6570 such cases but not in others.
6571 * src/reader.c (reader): Just return if a complaint has been issued,
6572 instead of exiting, so that 'main' can report times.
6574 2002-10-22 Akim Demaille <akim@epita.fr>
6576 * src/system.h: Include sys/types.
6577 Reported by Bert Deknuydt.
6579 2002-10-23 Paul Eggert <eggert@twinsun.com>
6581 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
6582 Suggested by Art Haas.
6584 2002-10-22 Paul Eggert <eggert@twinsun.com>
6586 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6587 decl; not needed any more.
6588 * src/main.c (main): Use return to exit, undoing yesterday's change.
6589 The last OS that we could find where this wouldn't work is
6590 SunOS 3.5, and that's too old to worry about now.
6592 * data/glr.c (struct yyltype): Define members even when not
6593 doing locations. This is more consistent with yacc.c, and it
6594 works around the following bug reports:
6595 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6596 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6598 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6599 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6600 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6602 2002-10-22 Akim Demaille <akim@epita.fr>
6606 2002-10-21 Paul Eggert <eggert@twinsun.com>
6608 Be consistent about 'bool'; the old code used an enum in one
6609 module and an int in another, and this violates the C standard.
6610 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6611 * configure.ac (AC_HEADER_STDBOOL): Add.
6612 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6613 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6614 * src/symtab.c (hash_compare_symbol_t): Likewise.
6615 * src/system.h (bool, false, true): Use a definition consistent
6616 with ../lib/hash.c. All uses changed.
6618 * src/complain.c (warning_issued): Renamed from warn_message_count,
6619 so that we needn't worry about integer overflow (!).
6620 Now of type bool. All uses changed.
6621 (complaint_issued): Renamed from complain_message_count; likewise.
6623 * src/main.c (main): Use exit to exit with failure.
6625 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6626 rather than 1 and 0.
6627 * src/main.c (main): Likewise.
6628 * src/getargs.c (getargs): Likewise.
6629 * src/reader.c (reader): Likewise.
6631 * src/getarg.c (getargs): Remove duplicate code for
6632 "Try `bison --help'".
6634 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6635 What was that "2" for?
6637 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6638 * src/getargs.c (usage): Likewise.
6640 * src/getargs.c (getargs): When there are too few operands, report
6641 the last one. When there are too many, report the first extra
6642 one. This is how diffutils does it.
6644 2002-10-20 Paul Eggert <eggert@twinsun.com>
6646 Remove K&R vestiges.
6647 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6648 * src/complain.c (VA_START): Remove. Assume prototypes.
6649 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6650 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6651 fatal): Assume prototypes.
6652 * src/complain.h: Assume prototypes.
6653 * src/system.h (PARAMS): Remove.
6654 Include <limits.h> unconditionally, since it's guaranteeed even
6655 for a freestanding C89 compiler.
6656 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
6657 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
6659 2002-10-20 Akim Demaille <akim@epita.fr>
6661 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
6662 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
6663 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
6664 (yyresolveStates, yyresolveAction, yyresolveStack)
6665 (yyprocessOneStack): Use them.
6666 (yy_reduce_print): New.
6667 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
6669 2002-10-20 Akim Demaille <akim@epita.fr>
6671 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
6672 arguments and output `void'.
6673 (b4_c_function): Rename as...
6674 (b4_c_function_def): this.
6675 (b4_c_function_decl, b4_c_ansi_function_def)
6676 (b4_c_ansi_function_decl): New.
6677 Change the interpretation of the arguments: before `int, foo', now
6679 * data/yacc.c (yyparse): Prototype and define thanks to these.
6680 Adjust b4_c_function_def uses.
6681 * data/glr.c (yyparse): Likewise, but ANSI only.
6683 2002-10-20 Akim Demaille <akim@epita.fr>
6685 * src/output.c (prepare): Move the definition of `tokens_number',
6686 `nterms_number', `undef_token_number', `user_token_number_max'
6688 (prepare_tokens): Here.
6689 (prepare_tokens): Rename as...
6690 (prepare_symbols): this.
6691 (prepare): Move the definition of `rules_number' to...
6692 (prepare_rules): here.
6693 (prepare): Move the definition of `last', `final_state_number',
6694 `states_number' to...
6695 (prepare_states): here.

6707 2002-10-20 Akim Demaille <akim@epita.fr>
6709 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
6710 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
6712 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
6714 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
6715 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
6718 2002-10-19 Paul Eggert <eggert@twinsun.com>
6720 Do not create a temporary file, as that involves security and
6721 cleanup headaches. Instead, use a pair of pipes.
6722 Derived from a suggestion by Florian Krohm.
6723 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
6724 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
6725 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
6726 (BISON_PREREQ_SUBPIPE): Add.
6727 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

6731 * src/output.c: Include "subpipe.h".
6732 (m4_invoke): Remove decl.
6733 (scan_skel): New decl.
6734 (output_skeleton): Use pipe rather than temporary file for m4 input.
6735 Check that m4sugar.m4 is readable, to avoid deadlock.
6736 Check for pipe I/O error.
6737 * src/scan-skel.l (readpipe): Remove decl.
6738 (scan_skel): New function, to be used in place of m4_invoke.
6739 Read from stream rather than file.
6741 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
6742 float, as this generates a warning on Solaris 8 + GCC 3.2 with
6743 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
6744 this generates a more-accurate value anyway.
6746 * lib/timevar.c (timervar_accumulate): Rename locals to
6747 avoid confusion with similarly-named more-global.
6748 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
6750 * src/output.c (prepare): Use xstrdup to convert char const *
6751 to char *, to avoid GCC warning.
6753 2002-10-19 Akim Demaille <akim@epita.fr>
6755 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
6756 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
6757 Use them to have `calc.y' ready for %pure-parser.
6758 * data/yacc.c (YYLEX): Pass a yylex return type to
6761 2002-10-19 Akim Demaille <akim@epita.fr>
6763 Prototype support of %lex-param and %parse-param.
6765 * src/parse-gram.y: Add the definition of the %lex-param and
6766 %parse-param tokens, plus their rules.
6767 Drop the `_' version of %glr-parser.
6769 * src/scan-gram.l (INITIAL): Scan them.
6770 * src/muscle_tab.c: Comment changes.
6771 (muscle_insert, muscle_find): Rename `pair' as `probe'.
6772 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
6773 (muscle_entry_s): The `value' member is no longer const.
6774 Adjust all dependencies.
6775 * src/muscle_tab.c (muscle_init): Adjust: use
6776 MUSCLE_INSERT_STRING.
6777 Initialize the obstack earlier.
6778 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
6779 (muscle_pair_list_grow): New.
6780 * data/c.m4 (b4_c_function_call, b4_c_args): New.

6785 2002-10-19 Akim Demaille <akim@epita.fr>
6787 * src/getargs.c (usage): Take status as argument and exit
6789 Report the traditional `Try ... --help' message when status != 0.
6790 (usage, version): Don't take a FILE * as arg, it is pointless.
6791 (getargs): When there is an incorrect number of arguments, make it
6792 an error, and report it GNUlically thanks to `usage ()'.
6794 2002-10-18 Paul Eggert <eggert@twinsun.com>
6796 * data/glr.c (yyreportParseError): Don't assume that sprintf
6797 yields the length of the printed string, as this is not true
6798 on SunOS 4.1.4. Reported by Peter Klein.
6800 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
6801 * tests/conflicts.at (%nonassoc and eof): Likewise.
6802 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
6804 2002-10-17 Akim Demaille <akim@epita.fr>
6806 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
6807 * src/getargs.c (trace_types, trace_args): Adjust.
6808 * src/reader.c (grammar_current_rule_prec_set)
6809 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
6810 Standardize error messages.
6812 (reader): Use trace_flag to enable scanner/parser debugging,
6813 instead of an adhoc scheme.
6814 * src/scan-gram.l: Remove trailing debugging code.
6816 2002-10-16 Paul Eggert <eggert@twinsun.com>
6818 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
6821 * NEWS: Officially drop support for building Bison with K&R C,
6822 since it didn't work anyway and it's not worth worrying about.
6823 * Makefile.maint (wget_files): Remove ansi2knr.c.
6824 (ansi2knr.c-url_prefix): Remove.
6825 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
6826 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6827 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6829 2002-10-15 Paul Eggert <eggert@twinsun.com>
6831 Stop using the "enum_" trick for K&R-style function definitions;
6832 it confused me, and I was the author! Instead, assume that people
6833 who want to use K&R C compilers (when using these modules in GCC,
6834 perhaps?) will run ansi2knr.
6836 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
6837 All uses of "enum_" changed to "enum ".
6838 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

6849 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
6850 Use function prototypes; this removes the need for declaring
6851 static functions simply to provide their prototypes.

6913 2002-10-14 Akim Demaille <akim@epita.fr>
6915 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
6918 2002-10-14 Akim Demaille <akim@epita.fr>
6920 * src/tables.c (table_ninf_remap): base -> tab.
6921 Reported by Matt Rosing.
6923 2002-10-14 Paul Eggert <eggert@twinsun.com>
6925 * tests/action.at, tests/calc.at, tests/conflicts.at,
6926 tests/cxx-type.at, tests/headers.at, tests/input.at,
6927 tests/regression.at, tests/synclines.at, tests/torture.at:
6928 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
6929 so that the tests still work even if POSIXLY_CORRECT is set.
6930 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
6932 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
6933 for portability to K&R hosts. Fix typo: signed char is guaranteed
6934 only to 127, not to 128.
6935 * data/glr.c (yysigned_char): New type.
6936 * data/yacc.c (yysigned_char): Likewise.
6937 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
6939 2002-10-13 Paul Eggert <eggert@twinsun.com>
6941 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
6942 true due to limited range of data type" warning from GCC.
6944 * data/c.m4 (b4_token_defines): Protect against double-inclusion
6945 by wrapping enum yytokentype's definition inside #ifndef
6946 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
6948 2002-10-13 Akim Demaille <akim@epita.fr>
6950 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
6951 Un yy- yyrhs to avoid the name clash with the global YYRHS.
6953 2002-10-13 Akim Demaille <akim@epita.fr>
6955 * Makefile.maint: Update from Autoconf 2.54.
6956 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
6958 2002-10-13 Akim Demaille <akim@epita.fr>
6960 * src/print.c (print_state): Separate the list of solved conflicts

6966 Let nondeterministic skeletons be usable with deterministic
6969 With the patch, GAWK compiled by GCC without -O2 passes its test
6970 suite using a GLR parser driven by LALR tables. It fails with -O2
6971 because `struct stat' gives two different answers on my machine:
6972 88 (definition of an auto var) and later 96 (memset on this var).
6973 Hence the stack is badly corrumpted. The headers inclusion is to
6974 blame: if I move the awk.h inclusion before GLR's system header
6975 inclusion, the two struct stat have the same size.
6977 * src/tables.c (pack_table): Always create conflict_table.
6978 (token_actions): Always create conflict_list.
6979 * data/glr.c (YYFLAG): Remove, unused.
6981 2002-10-13 Akim Demaille <akim@epita.fr>
6983 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
6985 (VALGRIND, GXX): New.
6986 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
6987 * tests/bison.in: Run $PREBISON a pre-command.
6988 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
6989 (maintainer-check-g++): New.
6990 * Makefile.am (maintainer-check): New.
6992 2002-10-13 Akim Demaille <akim@epita.fr>
6994 * data/glr.c: Formatting changes.
6995 Tweak some trace messages to match yacc.c's.
6997 2002-10-13 Akim Demaille <akim@epita.fr>
6999 GLR parsers sometimes raise parse errors instead of performing the
7001 Reported by Charles-Henry de Boysson.
7003 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7004 check the length of the traces when %glr.
7005 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7007 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7009 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7010 (yyltype): Remove the yy prefix from the member names.
7011 (yytable): Complete its comment.
7012 (yygetLRActions): Map error action number from YYTABLE from
7014 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7015 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7016 not satisfying as we could compare an YYACTION computed from
7017 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7018 only value for error actions.
7019 (yyreportParseError): In verbose parse error messages, don't issue
7020 `error' in the list of expected tokens.
7021 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7022 next action to perform to match glr.c's decoding.
7023 (yytable): Complete its comment.

7027 Fix problem reported by Henrik Grubbstroem in
7028 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
7029 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7030 because the Bison parser reads the second action before reducing
7032 * src/scan-gram.l (rule_length): New static var.
7033 Use it to keep track of the rule length in the scanner, since
7034 we can't expect the parser to be in lock-step sync with the scanner.
7035 (handle_action_dollar, handle_action_at): Use this var.
7036 * tests/actions.at (Exotic Dollars): Test for the problem.
7038 2002-10-12 Paul Eggert <eggert@twinsun.com>
7040 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
7041 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.

7043 Use same include order as source.
7044 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
7045 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
7047 * lib/timevar.c: Update copyright date and clarify comments.
7048 (get_time) [IN_GCC]: Keep the GCC version for reference.
7050 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7051 GCC version as of today, then merge Bison's changes.
7052 Change "GCC" to "Bison" in copyright notice. timevar.def's
7053 author is Akim, so change that too.
7055 * src/reader.c (grammar_current_rule_check):
7056 Don't worry about the default action if $$ is untyped.
7057 Prevents bogus warnings reported by Jim Gifford in
7058 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
7060 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
7061 * data/glr.c, data/lalr1.cc, data/yacc.c:
7062 Output token definitions before the first part of user declarations.
7063 Fixes compatibility problem reported by Jim Gifford for kbd in
7064 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
7066 2002-10-11 Paul Eggert <eggert@twinsun.com>
7068 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
7069 (yyparse): here. This undoes some of the 2002-07-25 change.
7070 Compatibility problem reported by Ralf S. Engelschall with
7071 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
7073 2002-10-11 Akim Demaille <akim@epita.fr>

7084 2002-10-10 Paul Eggert <eggert@twinsun.com>
7086 Portability fixes for bitsets; this also avoids several GCC
7089 * lib/abitset.c: Include <stddef.h>, for offsetof.
7090 * lib/lbitset.c: Likewise.
7092 * lib/abitset.c (abitset_bytes): Return a size that is aligned
7093 properly for vectors of objects. Do not assume that adding a
7094 header size to a multiple of a word size yields a value that is
7095 properly aligned for the whole union.
7096 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7098 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
7099 unique names for structures.
7100 * lib/ebitset.c (ebitset_bytes): Likewise.
7101 * lib/lbitset.c (lbitset_bytes): Likewise.
7103 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

7108 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
7109 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
7110 to improve the type-checking that GCC can do.
7111 * lib/bitset.c (bitset_op4_cmp): Likewise.
7112 * lib/bitset_stats.c (bitset_stats_count,
7113 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

7128 * lib/ebitset.h: Likewise.
7129 * lib/lbitset.h: Likewise.
7131 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
7132 All instances of parameters of type enum bitset_opts are now of
7133 type enum_bitset_opts, to conform to the C Standard, and similarly
7134 for enum_bitset_type.
7135 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
7136 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
7138 Do not use "struct bitset_struct" to mean different things in
7139 different modules. Not only is this confusing, it violates
7140 the C Standard, which requires that structure types in different
7141 modules must be compatible if one is to be passed to the other.
7142 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
7143 All instances of "struct bitset_struct *" replaced with "bitset".
7144 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
7145 (union bitset_union, struct abitset_struct, struct ebitset_struct,
7146 struct lbitset_struct, struct bitset_stats_struct): New types.
7147 All uses of struct bitset_struct changed to union bitset_union,

7150 struct bitset_struct): Remove.
7151 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
7152 struct bitset_struct): Remove.
7153 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
7154 bitset_struct): Remove.
7155 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
7158 Do not call a function of type T using a call that assumes the
7159 function is of a different type U. Standard C requires that a
7160 function must be called with a type that is compatible with its
7162 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
7164 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):

7174 lbitset_xor): New functions.
7175 (lbitset_vtable): Use them.
7177 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
7180 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
7182 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
7183 Use offsetof, for simplicity.
7185 2002-10-06 Paul Eggert <eggert@twinsun.com>
7187 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
7188 the same width as int. This reapplies a hunk of the 2002-08-12 patch
7189 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7190 which was inadvertently undone by the 2002-09-30 patch.
7191 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
7192 the same width as int.
7194 2002-10-04 Paul Eggert <eggert@twinsun.com>
7198 * configure.ac (AC_INIT), NEWS: Increment version number.
7200 * doc/bison.texinfo: Minor spelling, grammar, and white space
7202 (Symbols): Mention that any negative value returned from yylex
7203 signifies end-of-input. Warn about negative chars. Mention
7204 the portable Standard C character set.
7206 The GNU coding standard says CFLAGS and YFLAGS are reserved
7207 for the installer to set.
7208 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
7209 * src/Makefile.am (AM_CFLAGS): Likewise.
7210 (AM_YFLAGS): Renamed from YFLAGS.
7212 Fix some MAX and MIN problems.

7215 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
7216 * src/reader.c (reader): Use it.
7218 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
7219 POSIX 1003.1-2001 has removed fgrep.
7221 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
7223 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
7224 interpreted as signed.
7225 * lib/ebitset.c (ebitset_list): Fix bug.
7227 2002-10-01 Paul Eggert <eggert@twinsun.com>

7290 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
7291 BITSET_SIZE_MAX): New macros.
7292 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
7293 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
7294 to BITSET_WINDEX_MAX.
7296 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
7297 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

7547 to minimize the number of warnings from xgettext.
7548 (handle_action_dollar, handle_action_at): Don't use isdigit,

7550 outside the C locale.
7552 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
7553 this is a GCC extension and is not portable to other compilers.
7555 * src/system.h (alloca): Use same pattern as ../lib/error.c.
7556 Do not include <ctype.h>; no longer needed.
7557 Do not include <malloc.h>; no longer needed (and generates

7560 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
7563 * tests/regression.at: Do not use 'cc -c input.c -o input';

7735 different: save its reduction (accept) instead of having a state

7792 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
7793 for the time being: %locations ought to provide it to yyerror.

7797 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

9957 * src/lex.c (parse_percent_token): Be sure to 0-end token_buffer
9959 Reported by Benoit Perrot.
9961 2002-03-04 Akim Demaille <akim@epita.fr>
9963 Use bitset operations when possible, not loops over bits.
9965 * src/conflicts.c (set_conflicts, count_sr_conflicts): Use
9967 * src/print.c (print_reductions): Use bitset_and, bitset_andn.
9968 * src/reduce.c (useless_nonterminals): Formatting changes.

9979 * src/lalr.c (F): Now a bitset*.
9980 Adjust all dependencies.

9989 * src/L0.c, src/LR0.h (nstates): Be size_t.
9990 Adjust comparisons (signed vs unsigned).

9998 Adjust all dependencies.
9999 (varsetsize): Remove, now unused.

10007 2002-03-04 Akim Demaille <akim@epita.fr>
10009 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
10011 2002-03-04 Akim Demaille <akim@epita.fr>
10013 * src/closure.c (ruleset): Be a bitset.
10014 (rulesetsize): Remove.

10023 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
10025 * data/bison.c++: Merge the two generated headers. Insert a copyright
10026 notice in each output file.
10028 2002-02-28 Akim Demaille <akim@epita.fr>
10030 * data/bison.c++: Copy the prologue of bison.simple to fetch
10031 useful M4 definitions, such as b4_header_guard.
10033 2002-02-25 Akim Demaille <akim@epita.fr>
10035 * src/getargs.c (version): Give the name of the authors, and use a
10036 translator friendly scheme for the bgr
10039 2002-02-25 Akim Demaille <akim@epita.fr>
10041 * src/output.c (header_output): Remove, now handled completely via
10044 2002-02-25 Akim Demaille <akim@epita.fr>
10046 * m4/m4.m4: New, from CVS Autoconf.
10047 * configure.in: Invoke it.

10053 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
10055 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
10056 * src/output.c (output_skeleton): Use mkstemp to create a real
10058 Move the filling of `skeleton' and its muscle to...
10060 (output): Move the definition of the prologue muscle to...
10062 * src/system.h (DEFAULT_TMPDIR): New.
10064 2002-02-14 Paul Eggert <eggert@twinsun.com>
10066 Remove the support for C++ namespace cleanliness; it was
10067 causing more problems than it was curing, since it didn't work
10068 properly on some nonstandard C++ compilers. This can wait
10069 for a proper C++ parser.
10071 * NEWS: Document this.
10072 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
10073 of C++, as it's treated like C now.
10074 * src/bison.simple (YYSTD): Remove.
10075 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
10076 Treat C++ just like Standard C instead of trying to support
10077 namespace cleanliness.

10081 * tests/regression.at (else): Adjust to Andreas' change.
10083 2002-02-14 Akim Demaille <akim@epita.fr>
10085 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
10087 2002-02-13 Andreas Schwab <schwab@suse.de>
10089 * src/output.c (output_rule_data): Don't output NULL, it might
10090 not be defined yet.
10092 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
10094 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
10095 (Copyright notice): Update.
10097 2002-02-11 Akim Demaille <akim@epita.fr>
10099 * tests/regression.at (%nonassoc and eof): Don't include
10100 nonportable headers.
10102 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
10104 * data/bison.c++: Correct error recovery. Make the user able to
10105 initialize the starting location.
10107 2002-02-07 Akim Demaille <akim@epita.fr>
10109 * tests/input.at: New.
10111 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10113 * data/bison.c++: Replace some direct m4 expansions by constants. Be
10114 more consistent when naming methods and variables. Put preprocessor
10115 directives around tables only needed for debugging.
10117 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10119 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
10121 (yy::b4_name::parse): Use print_.
10123 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10125 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
10127 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10129 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
10131 (yy::b4_name::parse): Build verbose error messages, and use error_.
10133 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10135 * data/bison.c++: Fix m4 quoting in comments.
10137 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10139 * data/bison.c++: Adjust the parser code. Fix some muscles that were
10140 not expanded by m4.
10142 2002-02-05 Akim Demaille <akim@epita.fr>
10144 * data/bison.c++: Adjust to the M4 back end.
10145 More is certainly needed.
10147 2002-02-05 Akim Demaille <akim@epita.fr>
10149 Give a try to M4 as a back end.
10151 * lib/readpipe.c: New, from wdiff.
10152 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
10154 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
10155 specific values. Now it is m4 that performs the lookup.
10156 * src/parse-skel.y: Remove.
10157 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
10158 * src/output.c (actions_output, guards_output)
10159 (token_definitions_output): No longer keeps track of the output
10160 line number, hence remove the second argument.
10161 (guards_output): Check against the guard member of a rule, not the
10164 (output_skeleton): Don't look for the skeleton location, let m4 do
10166 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
10168 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
10169 (prepare): Given that for the time being changesyntax is not
10170 usable in M4, rename the muscles using `-' to `_'.
10171 Define `defines_flag', `output_parser_name' and `output_header_name'.
10172 * src/output.h (actions_output, guards_output)
10173 (token_definitions_output): Adjust prototypes.
10174 * src/scan-skel.l: Instead of scanning the skeletons, it now
10175 processes the output of m4: `__oline__' and `#output'.
10176 * data/bison.simple: Adjust to be used by M4(sugar).
10177 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
10179 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
10180 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
10181 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
10182 shamelessly stolen from CVS Autoconf.
10184 2002-02-05 Akim Demaille <akim@epita.fr>
10186 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
10187 * configure.in: Check for the declarations of free and malloc.
10188 * src/muscle_tab.c: Adjust.
10190 2002-02-05 Akim Demaille <akim@epita.fr>
10192 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
10193 which have no values.
10195 2002-02-05 Akim Demaille <akim@epita.fr>
10197 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
10200 2002-01-29 Paul Eggert <eggert@twinsun.com>
10202 * src/bison.simple (YYSIZE_T): Do not define merely because
10203 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10204 On some platforms, <alloca.h> does not declare YYSTD (size_t).
10206 2002-01-27 Akim Demaille <akim@epita.fr>
10208 Fix `%nonassoc and eof'.
10210 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10211 which were not properly copied! Replace
10212 memcpy (res->errs, src->errs, src->nerrs);
10214 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10216 * tests/regression.at (%nonassoc and eof): Adjust to newest
10217 Autotest: `.' is not in the PATH.
10219 2002-01-27 Akim Demaille <akim@epita.fr>
10221 * tests/sets.at (AT_EXTRACT_SETS): New.
10222 (Nullable): Use it.
10225 2002-01-26 Akim Demaille <akim@epita.fr>
10227 * tests/actions.at, tests/calc.at, tests/headers.at,
10228 * tests/torture.at: Adjust to the newest Autotest which no longer
10229 forces `.' in the PATH.
10231 2002-01-25 Akim Demaille <akim@epita.fr>
10233 * tests/regression.at (%nonassoc and eof): New.
10234 Suggested by Robert Anisko.
10236 2002-01-24 Akim Demaille <akim@epita.fr>
10238 Bison dumps core when trying to complain about broken input files.
10239 Reported by Cris van Pelt.
10241 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10242 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10244 (Invalid inputs): Strengthen: exercise parse_percent_token.
10246 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10248 * src/Makefile.am: Add bison.c++.
10249 * src/bison.c++: New skeleton.
10251 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10255 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10257 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10259 2002-01-20 Marc Autret <marc@gnu.org>
10261 * src/files.c (compute_output_file_names): Fix
10263 2002-01-20 Marc Autret <marc@gnu.org>
10265 * tests/output.at: New test.
10266 * src/files.c (compute_base_names): Don't map extensions when
10267 the YACC flag is set, use defaults.
10268 Reported by Evgeny Stambulchik.
10270 2002-01-20 Marc Autret <marc@gnu.org>
10272 * src/system.h: Need to define __attribute__ away for non-GCC
10273 compilers as well (i.e., the vendor C compiler).
10274 Suggested by Albert Chin-A-Young.
10276 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10278 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10279 canonical definition.
10280 * src/system.h: Use the canonical definition for PARAMS (avoids
10281 a conflict with the macro from lib/hash.h).
10283 2002-01-11 Akim Demaille <akim@epita.fr>
10285 * configure.in: Use AC_FUNC_STRNLEN.
10286 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10288 2002-01-09 Akim Demaille <akim@epita.fr>
10290 * src/files.c, src/files.h (output_infix): New.
10291 (tab_extension): Remove.
10292 (compute_base_names): Compute the former, drop the latter.
10293 * src/output.c (prepare): Insert the muscles `output-infix', and
10295 * src/parse-skel.y (string, string.1): New.
10296 (section.header): Use it.
10297 (section.yacc): Remove.
10298 (prefix): Remove too.
10299 * src/scan-skel.l: Adjust.
10300 * src/bison.simple, src/bison.hairy: Adjust.
10302 2002-01-09 Akim Demaille <akim@epita.fr>
10304 * configure.in (WERROR_CFLAGS): Compute it.
10305 * src/Makefile.am (CFLAGS): Pass it.
10306 * tests/atlocal.in (CFLAGS): Idem.
10307 * src/files.c: Fix a few warnings.
10308 (get_extension_index): Remove, unused.
10310 2002-01-08 Akim Demaille <akim@epita.fr>
10312 * src/getargs.c (AS_FILE_NAME): New.
10313 (getargs): Use it to convert DOSish file names.
10314 * src/files.c (base_name): Rename as full_base_name to avoid
10315 clashes with `base_name ()'.
10316 (filename_split): New.
10317 (compute_base_names): N-th rewrite, using filename_split.
10319 2002-01-08 Akim Demaille <akim@epita.fr>
10321 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10322 New, stolen from the Fileutils 4.1.
10323 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10324 * configure.in: Check for the presence of memrchr, and of its
10327 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10329 * lib/hash.h (__P): Added definition for this macro.
10330 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10331 BUILT_SOURCES, to ensure they are generated first.
10332 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10333 %error-verbose to allow bootstrapping with bison 1.30x.
10335 2002-01-06 Akim Demaille <akim@epita.fr>
10337 * src/reader.c (parse_braces): Don't fetch the next char, the
10338 convention is to fetch on entry.
10339 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10340 'switch' without a following semicolon.
10341 * tests/regression.at (braces parsing): New.
10343 2002-01-06 Akim Demaille <akim@epita.fr>
10345 Bison is dead wrong in its RR conflict reports.
10347 * tests/torture.at (GNU Cim Grammar): New.
10348 * src/conflicts.c (count_rr_conflicts): Fix.
10350 2002-01-06 Akim Demaille <akim@epita.fr>
10352 Creating package.m4 from configure.ac causes too many problems.
10354 * tests/Makefile.am (package.m4): Create it by hand,
10355 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10357 2002-01-06 Akim Demaille <akim@epita.fr>
10359 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10362 2002-01-04 Paul Eggert <eggert@twinsun.com>
10364 * doc/bison.texinfo (Debugging):
10365 Remove YYSTDERR; it's no longer defined or used.
10366 Also, s/cstdio.h/cstdio/.
10368 2002-01-03 Akim Demaille <akim@epita.fr>
10370 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10372 2002-01-03 Akim Demaille <akim@epita.fr>
10374 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10375 tracing code to --trace, wait for a better --trace option, with
10378 2002-01-03 Akim Demaille <akim@epita.fr>
10380 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10381 The ISO C++ standard is extremely clear about it: stderr is
10382 considered a macro, not a regular symbol (see table 94 `Header
10383 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10384 Therefore std:: does not apply to it. It still does with fprintf.
10385 Also, s/cstdio.h/cstdio/.
10387 2002-01-03 Akim Demaille <akim@epita.fr>
10389 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10390 for non system headers.
10392 2002-01-02 Akim Demaille <akim@epita.fr>
10394 Equip the skeleton chain with location tracking, runtime trace,
10395 pure parser and scanner.
10397 * src/parse-skel.y: Request a pure parser, locations, and prefix
10399 (%union): Having several members with the same type does not help
10400 type mismatches, simplify.
10401 (YYPRINT, yyprint): New.
10402 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10403 (skel_error): this.
10405 * src/scan-skel.l: Adjust to these changes.
10406 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10407 (LOCATION_PRINT, skel_control_t): New.
10409 2001-12-30 Akim Demaille <akim@epita.fr>
10411 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10412 replace `gb' with BLANKS.
10413 * src/scan-skel.l: Adjust.
10415 2001-12-30 Akim Demaille <akim@epita.fr>
10417 * src/system.h: We don't need nor want bcopy.
10418 Throw away MS-DOS crap: we don't need getpid.
10419 * configure.in: We don't need strndup. It was even causing
10420 problems: because Flex includes the headers *before* us,
10421 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10423 * lib/xstrndup.c: New.
10424 * src/scan-skel.l: Use it.
10425 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10426 * src/parse-skel.y: Use %directives instead of #defines.
10428 2001-12-30 Akim Demaille <akim@epita.fr>
10430 * src/skeleton.h: New.
10431 * src/output.c (output_parser, output_master_parser): Remove, dead
10433 * src/output.h (get_lines_number, actions_output, guards_output)
10434 (token_definitions_output): Prototype them.
10435 * src/parse-skel.y: Add the license notice.
10436 Include output.h and skeleton.h.
10437 (process_skeleton): Returns void, and takes a single parameter.
10438 * src/scan-skel.l: Add the license notice.
10439 Include skeleton.h.
10440 Don't use %option yylineno: it seems that then Flex imagines
10441 REJECT has been used, and therefore it won't reallocate its
10442 buffers (which makes no other sense to me than a bug). It results
10443 in warnings for `unused: yy_flex_realloc'.
10445 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10447 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10448 (MUSCLE_INSERT_PREFIX): ...to there.
10449 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10450 (MUSCLE_INSERT_PREFIX): Move from here...
10452 * src/bison.hairy: Add a section directive. Put braces around muscle
10453 names. This parser skeleton is still broken, but Bison should not
10454 choke on a bad muscle 'syntax'.
10455 * src/bison.simple: Add a section directive. Put braces around muscle
10458 * src/files.h (strsuffix, stringappend): Add declarations.
10459 (tab_extension): Add declaration.
10460 (short_base_name): Add declaration.
10462 * src/files.c (strsuffix, stringappend): No longer static. These
10463 functions are used in the skeleton parser.
10464 (tab_extension): New.
10465 (compute_base_names): Use the computations done in this function
10466 to guess if the generated parsers should have '.tab' in their
10468 (short_base_name): No longer static.
10470 * src/output.c (output_skeleton): New.
10471 (output): Disable call to output_master_parser, and give a try to
10472 a new skeleton handling system.

10484 2001-12-29 Akim Demaille <akim@epita.fr>
10486 %name-prefix is broken.
10488 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10489 Adjust all dependencies.
10490 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10493 Renaming yylval but not yylloc is not consistent. Now we do.
10495 * src/bison.simple: Prefix yylloc if used.
10496 * doc/bison.texinfo (Decl Summary): Document that.
10498 2001-12-29 Akim Demaille <akim@epita.fr>
10500 * doc/bison.texinfo: Promote `%long-directive' over
10502 Remove all references to fixed-output-files, yacc is enough.
10504 2001-12-29 Akim Demaille <akim@epita.fr>
10506 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10507 user prologue. These are defaults.
10508 * tests/actions.at (Mid-rule actions): Make sure the user can
10509 define YYDEBUG and YYERROR_VERBOSE.
10511 2001-12-29 Akim Demaille <akim@epita.fr>
10513 * src/output.c (header_output): Don't forget to export YYLTYPE and
10515 * tests/headers.at (export YYLTYPE): New, make sure it does.
10516 * tests/regression.at (%union and --defines, Invalid CPP headers):
10518 * tests/headers.at: here.
10520 2001-12-29 Akim Demaille <akim@epita.fr>

10524 2001-12-29 Akim Demaille <akim@epita.fr>
10526 * tests/actions.at (Mid-rule actions): Output on a single line
10527 instead of several.
10529 2001-12-29 Akim Demaille <akim@epita.fr>
10531 * doc/bison.texinfo: Formatting changes.
10533 2001-12-29 Akim Demaille <akim@epita.fr>
10535 Don't store the token defs in a muscle, just be ready to output it
10536 on command. Now possible via `symbols'. Fixes a memory leak.
10538 * src/output.c (token_definitions_output): New.
10539 (output_parser, header_output): Use it.
10540 * src/reader.c (symbols_save): Remove.
10542 2001-12-29 Akim Demaille <akim@epita.fr>
10544 * src/bison.simple: Do not provide a default for YYSTYPE and
10545 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10548 2001-12-29 Akim Demaille <akim@epita.fr>
10550 Mid-rule actions are simply... ignored!
10552 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10553 the empty-rule associated to the dummy symbol, not to the host
10555 * tests/actions.at (Mid-rule actions): New.
10557 2001-12-29 Akim Demaille <akim@epita.fr>
10561 * src/reader.c (reader): Free grammar.
10563 2001-12-29 Akim Demaille <akim@epita.fr>
10567 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10568 since it allocates it for each state, although only one is needed.
10569 (allocate_storage): Do it here.
10571 2001-12-29 Akim Demaille <akim@epita.fr>
10573 * src/options.h, src/options.c (create_long_option_table): Rename
10575 (long_option_table_new): this, with a clearer prototype.
10576 (percent_table): Remove, unused,
10577 * src/getargs.c (getargs): Adjust.
10579 2001-12-29 Akim Demaille <akim@epita.fr>
10581 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

10585 2001-12-29 Akim Demaille <akim@epita.fr>
10587 * src/lalr.c (build_relations): Rename `states' as `states1'.
10588 Sorry, I don't understand exactly what it is, no better name...
10590 2001-12-29 Akim Demaille <akim@epita.fr>
10592 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10593 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

10609 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

10621 * src/reader.c (packsymbols): Fill this table.
10623 * src/conflicts.c (resolve_sr_conflict): Adjust.
10624 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10626 Use symbols[i]->tag instead of tags[i].
10628 2001-12-29 Akim Demaille <akim@epita.fr>
10630 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10631 In addition, put a comment in there, to replace...
10632 * tests/regression.at (%union and C comments): Remove.
10634 2001-12-29 Akim Demaille <akim@epita.fr>
10636 * tests/regression.at (Web2c Actions): Blindly move the actual
10637 output as expected output. The contents *seem* right to me, but I
10638 can't pretend reading perfectly parser tables... Nonetheless, all
10639 the other tests pass correctly, the table look OK, even though the
10640 presence of `$axiom' is to be noted: AFAICS it is useless (but
10643 2001-12-29 Akim Demaille <akim@epita.fr>
10645 * src/reader.c (readgram): Don't add the rule 0 if there were no
10646 rules read. In other words, add it _after_ having performed
10647 grammar sanity checks.
10648 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10650 2001-12-29 Akim Demaille <akim@epita.fr>
10652 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10653 visible, and some states have now a different number.
10655 2001-12-29 Akim Demaille <akim@epita.fr>
10657 * src/reader.c (readgram): Bind the initial rule's lineno to that
10659 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
10660 (Solved SR Conflicts): Adjust rule 0's line number.
10662 2001-12-29 Akim Demaille <akim@epita.fr>
10664 Fix the `GAWK Grammar' failure.
10666 * src/LR0.c (final_state): Initialize to -1 so that we do compute
10667 the reductions of the first state which was mistakenly confused
10668 with the final state because precisely final_state was initialized
10670 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
10671 now noticed by Bison.
10672 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
10673 have a reduction on $default.
10675 2001-12-29 Akim Demaille <akim@epita.fr>
10677 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
10679 * src/closure.c (print_closure): Likewise.
10680 * src/derives.c (print_derives): Likewise.
10681 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
10684 2001-12-29 Akim Demaille <akim@epita.fr>
10686 * src/lalr.c (lookaheads_print): New.
10687 (lalr): Call it when --trace-flag.
10688 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
10691 2001-12-29 Akim Demaille <akim@epita.fr>
10693 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
10694 when walking through ritem, even via rule->rhs.
10695 * src/reduce.c (dump_grammar, useful_production, reduce_output)
10696 (useful_production, useless_nonterminals): Likewise.
10697 (reduce_grammar_tables): Likewise, plus update nritems.
10698 * src/nullable.c (set_nullable): Likewise.
10699 * src/lalr.c (build_relations): Likewise.
10700 * tests/sets.at (Nullable): Adjust.
10701 Fortunately, now, the $axiom is no longer nullable.
10703 2001-12-29 Akim Demaille <akim@epita.fr>
10705 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

10713 2001-12-29 Akim Demaille <akim@epita.fr>
10715 * src/output.c: Comment changes.
10717 2001-12-27 Paul Eggert <eggert@twinsun.com>
10719 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
10720 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
10721 Sparc, as they were causing more porting problems than the
10722 (minor) performance improvement was worth.
10724 Also, catch up with 1.31's YYSTD.
10726 2001-12-27 Akim Demaille <akim@epita.fr>
10728 * src/output.c (output_gram): Rely on nritems, not the
10729 0-sentinel. See below.
10730 Use -1 as separator, not 0.
10731 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
10732 Rely on -1 as separator in yyrhs, instead of 0.
10733 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
10734 twice `Now at end of input', therefore there are two lines less to
10737 2001-12-27 Akim Demaille <akim@epita.fr>
10739 * tests/regression.at (Unresolved SR Conflicts):
10740 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
10743 2001-12-27 Akim Demaille <akim@epita.fr>
10745 * src/LR0.c (new_state): Recognize the final state by the fact it
10746 is reached by eoftoken.
10747 (insert_start_shifting_state, insert_eof_shifting_state)
10748 (insert_accepting_state, augment_automaton): Remove, since now
10749 these states are automatically computed from the initial state.
10750 (generate_states): Adjust.
10751 * src/print.c: When reporting a rule number to the user, substract
10752 1, so that the axiom rule is rule 0, and the first user rule is 1.
10753 * src/reduce.c: Likewise.
10754 * src/print_graph.c (print_core): For the time being, just as for
10755 the report, depend upon --trace-flags to dump the full set of
10757 * src/reader.c (readgram): Once the grammar read, insert the rule
10758 0: `$axiom: START-SYMBOL $'.
10759 * tests/set.at: Adjust: rule 0 is now displayed, and since the
10760 number of the states has changed (the final state is no longer
10761 necessarily the last), catch up.
10763 2001-12-27 Akim Demaille <akim@epita.fr>
10765 Try to make the use of the eoftoken valid. Given that its value
10766 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
10767 is used instead of > 0 where appropriate, (ii), depend upon nritems
10768 instead of the 0-sentinel.
10770 * src/gram.h, src/gram.c (nritems): New.
10771 Expected to be duplication of nitems, but for the time being...
10772 * src/reader.c (packgram): Assert nritems and nitems are equal.
10773 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
10774 * src/closure.c (print_closure, print_fderives): Likewise.

10779 2001-12-27 Akim Demaille <akim@epita.fr>
10781 * src/main.c (main): If there are complains after grammar
10782 reductions, then output the report anyway if requested, then die.
10783 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
10784 * src/reader.c (eoftoken): New.
10785 (parse_token_decl): If the token being defined has value `0', it
10787 (packsymbols): No longer hack `tags' to insert `$' by hand.
10788 Be sure to preserve the value of the eoftoken.
10789 (reader): Make sure eoftoken is defined.
10790 Initialize nsyms to 0: now eoftoken is created just like the others.
10791 * src/print.c (print_grammar): Don't special case the eof token.
10792 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
10793 lie anyway, albeit pleasant.
10794 * tests/calc.at: Exercise error messages with eoftoken.
10795 Change the grammar so that empty input is invalid.
10796 Adjust expectations.
10797 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
10799 2001-12-27 Akim Demaille <akim@epita.fr>
10801 * configure.in: Check the protos of strchr ans strspn.
10802 Replace strchr if needed.
10803 * src/system.h: Provide the protos of strchr, strspn and memchr if
10805 * lib/strchr.c: New.
10806 * src/reader.c (symbols_save): Use strchr.
10808 2001-12-27 Akim Demaille <akim@epita.fr>
10810 * src/print.c, src/print_graph.c (escape): New.
10811 Use it to quote the TAGS outputs.
10812 * src/print_graph.c (print_state): Now errors are in red, and
10813 reductions in green.
10814 Prefer high to wide: output the state number on a line of its own.
10816 2001-12-27 Akim Demaille <akim@epita.fr>
10818 * src/state.h, src/state.c (reductions_new): New.
10819 * src/LR0.c (set_state_table): Let all the states have a
10820 `reductions', even if reduced to 0.
10821 (save_reductions): Adjust.

10839 2001-12-27 Akim Demaille <akim@epita.fr>
10841 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
10842 * src/print.c: here.
10843 (lookaheadset, shiftset): New, used as additional storage by
10845 (print_results): Adjust.
10846 (print_shifts, print_gotos, print_errs): New, extracted from...
10847 (print_actions): here.
10848 * src/print_graph.c (print_actions): Remove dead code.
10850 2001-12-27 Akim Demaille <akim@epita.fr>
10852 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
10855 2001-12-27 Akim Demaille <akim@epita.fr>
10857 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
10858 (build_relations): Adjust.
10860 2001-12-27 Akim Demaille <akim@epita.fr>
10862 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
10865 2001-12-27 Akim Demaille <akim@epita.fr>
10867 * src/reader.c (packgram): Catch nitems overflows.
10869 2001-12-27 Akim Demaille <akim@epita.fr>

10872 * src/output.c (output): Adjust.
10873 * src/reader.c (parse_braces): New, factoring...
10874 (copy_action, copy_guard): these two which are renamed as...
10875 (parse_action, parse_guard): these.
10876 As a voluntary consequence, using braces around guards is now
10879 2001-12-27 Akim Demaille <akim@epita.fr>
10881 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
10882 * src/reader.c (symbol_list): `guard' and `guard_line' are new
10884 (symbol_list_new): Adjust.
10885 (copy_action): action_line is the first line, not the last.
10886 (copy_guard): Just as for actions, store the `action' only, not
10887 the switch/case/break flesh.
10888 Don't parse the user action that might follow the guard, let...
10889 (readgram): do it, i.e., now, there can be an action after a
10891 In other words the guard is just explicitly optional.
10892 (packgram): Adjust.
10893 * src/output.c (guards_output): New.
10894 (output_parser): Call it when needed.
10895 (output): Also free the guard and attrs obstacks.
10896 * src/files.c, src/files.h (obstack_save): Remove.
10897 (output_files): Remove.
10898 As a result, if one needs the former `.act' file, using an
10899 appropriate skeleton which requires actions and guards is now
10901 * src/main.c (main): Adjust.
10902 * tests/semantic.at: New.
10903 * tests/regression.at: Use `input.y' as input file name.
10904 Avoid 8+3 problems by requiring input.c when the test needs the

10909 * src/reader.c (symbol_list_new): Be sure to initialize all the
10912 2001-12-27 Akim Demaille <akim@epita.fr>
10914 All the hacks using a final pseudo state are now useless.
10916 * src/LR0.c (set_state_table): state_table holds exactly nstates.
10917 * src/lalr.c (nLA): New.
10918 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
10919 instead of lookaheadsp from the pseudo state (nstate + 1).
10921 2001-12-27 Akim Demaille <akim@epita.fr>
10923 * src/output.c (action_row, token_actions): Use a state_t instead
10924 of a integer, and nlookaheads instead of the following state's

10931 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
10932 (conflicts_print, print_reductions): Use a state_t instead of an
10933 integer when referring to a state.
10934 As much as possible, depend upon nlookaheads, instead of the
10935 `lookaheadsp' member of the following state (since lookaheads of
10936 successive states are successive, the difference between state n + 1
10937 and n served as the number of lookaheads for state n).
10938 * src/lalr.c (add_lookback_edge): Likewise.
10939 * src/print.c (print_core, print_actions, print_state)
10940 (print_results): Likewise.

10947 * src/bison.hairy: Formatting/comment changes.
10949 Remove `register' indications.
10950 Add plenty of `static'.
10952 2001-12-27 Akim Demaille <akim@epita.fr>
10954 * src/output.c (prepare): Drop the muscle `ntbase' which
10955 duplicates ntokens.
10956 * src/bison.simple: Formatting/comment changes.
10957 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
10958 is an undocumented synonym.
10960 2001-12-22 Akim Demaille <akim@epita.fr>
10962 * src/output.c (output_table_data): Change the prototype to use
10963 `int' for array ranges: some invocations do pass an int, not a
10965 Reported by Wayne Green.
10967 2001-12-22 Akim Demaille <akim@epita.fr>
10969 Some actions of web2c.y are improperly triggered.
10970 Reported by Mike Castle.
10972 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

10974 (Web2c Report): this.
10975 (Web2c Actions): New.
10977 2001-12-22 Akim Demaille <akim@epita.fr>
10979 Reductions in web2c.y are improperly reported.
10980 Reported by Mike Castle.
10982 * src/conflicts.c (print_reductions): Fix.
10983 * tests/regression.at (Web2c): New.
10985 2001-12-18 Akim Demaille <akim@epita.fr>
10987 Some host fail on `assert (!"foo")', which expands to
10988 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
10989 Reported by Nelson Beebee.
10991 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
10992 `#define it_succeeded 0' and `assert (it_succeeded)'.
10994 2001-12-17 Marc Autret <autret_m@epita.fr>
10996 * src/bison.simple: Don't hard code the skeleton line and filename.
10997 * src/output.c (output_parser): Rename 'line' as 'output_line'.
10998 New line counter 'skeleton_line' (skeleton-line muscle).
11000 2001-12-17 Paul Eggert <eggert@twinsun.com>
11002 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11003 YYDEBUG must be defined to a nonzero value.
11005 * src/bison.simple (yytname): Do not assume that the user defines
11006 YYDEBUG to a properly parenthesized expression.
11008 2001-12-17 Akim Demaille <akim@epita.fr>
11010 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
11011 nlookaheads is a new member.
11013 * src/lalr.h (nlookaheads): Remove this orphan declaration.
11014 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
11017 2001-12-17 Akim Demaille <akim@epita.fr>
11019 * src/files.h, src/files.c (open_files, close_files): Remove.
11020 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11022 * src/reader.c (reader): Do it.
11024 2001-12-17 Akim Demaille <akim@epita.fr>
11026 * src/conflicts.c (print_reductions): Formatting changes.
11028 2001-12-17 Akim Demaille <akim@epita.fr>
11030 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
11031 (flush_reduce): New.
11032 (resolve_sr_conflict): Adjust.
11034 2001-12-17 Akim Demaille <akim@epita.fr>
11036 * src/output.c (output_obstack): Be static and rename as...
11037 (format_obstack): this, to avoid any confusion with files.c's
11039 * src/reader.h (muscle_obstack): Move to...
11040 * src/output.h: here, since it's defined in output.c.
11042 2001-12-17 Akim Demaille <akim@epita.fr>
11044 * src/output.c (action_row, save_column, default_goto)
11045 (sort_actions, matching_state, pack_vector): Better variable
11048 2001-12-17 Akim Demaille <akim@epita.fr>
11050 * src/output.c: Various formatting changes.
11052 2001-12-17 Akim Demaille <akim@epita.fr>
11054 * src/files.c (output_files): Free the output_obstack.
11055 * src/main.c (main): Call print and print_graph conditionally.
11056 * src/print.c (print): Work unconditionally.
11057 * src/print_graph.c (print_graph): Work unconditionally.
11058 * src/conflicts.c (log_resolution): Output only if verbose_flag.
11060 2001-12-16 Marc Autret <autret_m@epita.fr>
11062 * src/output.c (actions_output): Fix. When we use %no-lines,
11063 there is one less line per action.
11065 2001-12-16 Marc Autret <autret_m@epita.fr>
11067 * src/bison.simple: Remove a useless #line directive.
11068 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
11069 * src/output.c (get_lines_number): New.
11070 (output_parser): Adjust, now takes care about the lines of a
11072 Fix line numbering.
11073 (actions_output): Computes the number of lines taken by actions.
11074 (output_master_parser): Insert new skeleton which is the name of
11075 the output parser file name.
11077 2001-12-15 Marc Autret <autret_m@epita.fr>
11079 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
11081 2001-12-15 Marc Autret <autret_m@epita.fr>
11083 * src/output.c (output_gram): Keep track of the hairy one.
11085 2001-12-15 Akim Demaille <akim@epita.fr>
11087 Make `make distcheck' work.
11089 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11090 system.h which uses libgettext.h.
11092 2001-12-15 Akim Demaille <akim@epita.fr>
11094 * src/nullable.c (set_nullable): Useless rules must be skipped,
11095 otherwise, since we range over their symbols, we might look at a
11096 nonterminal which no longer ``exists'', i.e., it is not counted in
11097 `nvars', hence we overflow our arrays.
11099 2001-12-15 Akim Demaille <akim@epita.fr>
11101 The header can also be produced directly, without any obstack!
11104 * src/files.c, src/files.h (defines_obstack): Remove.
11105 (compute_header_macro): Global.
11106 (defines_obstack_save): Remove.
11107 * src/reader.c (parse_union_decl): No longer output to
11108 defines_obstack: its content can be found in the `stype' muscle
11110 (output_token_translations): Merge into...
11111 (symbols_output): this.
11113 (symbols_save): this.
11115 * src/output.c (header_output): New.
11118 2001-12-15 Akim Demaille <akim@epita.fr>
11120 * src/reader.c (parse_union_decl): Instead of handling two obstack
11121 simultaneously, use one to define the `stype' muscle, and use the
11122 value of the latter to fill defines_obstack.
11123 (copy_comment): Remove.
11124 (copy_comment2): Work for a single obstack.
11126 (copy_comment): this.
11128 2001-12-15 Akim Demaille <akim@epita.fr>
11130 * src/lex.c, src/lex.h (xgetc): No longer static.
11131 * src/reader.c (parse_union_decl): Revamp.
11133 2001-12-15 Akim Demaille <akim@epita.fr>
11135 Still making progress in separating Bison into (i) input, (ii)
11136 process, (iii) output: now we can directly output the parser file
11137 without using table_obstack at all.
11139 * src/files.c, src/files.h (table_obstack): Bye bye.
11140 (parser_file_name): New.
11141 * src/files.c (compute_output_file_names): Compute it.
11142 * src/output.c (actions_output, output_parser)
11143 (output_master_parser): To a file instead of an obstack.
11145 2001-12-15 Akim Demaille <akim@epita.fr>
11147 Attach actions to rules, instead of pre-outputting them to
11150 * src/gram.h (rule_t): action and action_line are new members.
11151 * src/reader.c (symbol_list): Likewise.
11152 (copy_action): Save the actions within the rule.
11153 (packgram): Save them in rule_table.
11154 * src/output.c (actions_output): New.
11155 (output_parser): Use it on `%%actions'.
11156 (output_rule_data): Don't free rule_table.
11158 (prepare): Don't save the `action' muscle.
11159 * src/bison.simple: s/%%action/%%actions/.
11161 2001-12-15 Akim Demaille <akim@epita.fr>
11163 * src/reader.c (copy_action): When --yacc, don't append a `;'
11164 to the user action: let it fail if lacking.
11165 Suggested by Arnold Robbins and Tom Tromey.
11167 2001-12-14 Akim Demaille <akim@epita.fr>
11169 * src/lex.c (literalchar): Simply return the char you decoded, non
11170 longer mess around with obstacks and int pointers.
11171 Adjust all callers.
11173 2001-12-14 Akim Demaille <akim@epita.fr>
11175 * src/lex.c (literalchar): Don't escape the special characters,
11176 just decode them, and keep them as char (before, eol was output as
11177 the 2 char string `\n' etc.).
11178 * src/output.c (output_rule_data): Use quotearg to output the
11181 2001-12-13 Paul Eggert <eggert@twinsun.com>
11183 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11184 Do not infringe on the global user namespace when using C++.
11185 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11186 All uses of `fprintf' and `stderr' changed.
11188 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11190 2001-12-13 Akim Demaille <akim@epita.fr>
11192 The computation of nullable is broken: it doesn't handle empty
11195 * tests/torture.at (GNU AWK Grammar): New.
11196 * tests/sets.at (Nullable): New.
11197 * src/nullable.c (set_nullable): Instead of blindly looping over
11198 `ritems', loop over the rules, and then over their rhs's.
11200 Work around Autotest bugs.
11202 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11203 frame, because Autotest understand lines starting with a `+' as
11204 traces from the shell. Then, they are not processed properly.
11205 Admittedly an Autotest bug, but we don't have time to wait for
11206 Autotest to catch up.
11207 * tests/regression.at (Broken Closure): Adjust to the new table
11210 * tests/sets.at: here.
11212 2001-12-13 Akim Demaille <akim@epita.fr>
11214 * src/closure.c (closure): Use nrules instead of playing tricks
11215 with BITS_PER_WORD.
11217 2001-12-13 Akim Demaille <akim@epita.fr>
11219 * src/print.c (print_actions): Output the handling of `$' as the
11220 traces do: shifting the token EOF. Before EOF was treated as a
11222 * tests/regression.at: Adjust some tests.
11223 * src/print_graph.c (print_core): Complete the set of items via
11224 closure. The next-to-final and final states are still unsatisfying,
11225 but that's to be addressed elsewhere.
11226 No longer output the rule numbers, but do output the state number.
11227 A single loop for the shifts + gotos is enough, but picked a
11228 distinct color for each.
11229 (print_graph): Initialize and finalize closure.
11231 2001-12-13 Akim Demaille <akim@epita.fr>
11233 * src/reader.c (readgram): Remove dead code, an strip useless
11235 (get_type): Remove, unused.
11237 2001-12-12 Akim Demaille <akim@epita.fr>
11239 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11240 on that of lib/error.c.
11242 2001-12-12 Akim Demaille <akim@epita.fr>
11244 Some hosts don't like `/' in includes.
11246 * src/system.h: Include libgettext.h without qualifying the path.
11247 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11250 2001-12-11 Marc Autret <autret_m@epita.fr>
11252 * src/output.c (output_parser): Remove useless muscle.
11254 2001-12-11 Marc Autret <autret_m@epita.fr>
11256 * src/bison.simple: Remove #line just before %%epilogue. It
11257 is now handled in ...
11258 * src/reader.c (read_additionnal_code): Add the output of a
11259 #line for the epilogue.
11261 2001-12-10 Marc Autret <autret_m@epita.fr>
11263 * src/reader.c (copy_definition): Re-use CPP-outed code which
11264 replace precedent remove.
11265 * src/bison.simple: Remove #line before %%prologue because
11266 %%input-line is wrong at this time.
11268 2001-12-10 Marc Autret <autret_m@epita.fr>
11270 * src/reader.c (symbols_output): Clean up.
11271 * src/output.c (output_gram, output): Clean up.
11273 2001-12-10 Akim Demaille <akim@epita.fr>
11275 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11276 * src/LR0.c (set_state_table): here.
11277 * src/lalr.c (lalr): Call it.
11279 2001-12-10 Akim Demaille <akim@epita.fr>
11281 * src/state.h (shifts): Remove the `number' member: shifts are
11282 attached to state, hence no longer need to be labelled with a
11285 2001-12-10 Akim Demaille <akim@epita.fr>
11287 Now that states have a complete set of members, the linked list of
11288 shifts is useless: just fill directly the state's shifts member.
11290 * src/state.h (shifts): Remove the `next' member.
11291 * src/LR0.c (first_state, last_state): Remove.
11292 Adjust the callers.
11293 (augment_automaton): Don't look for the shifts that must be added
11294 a shift on EOF: it is those of the state we looked for! But now,
11295 since shifts are attached, it is no longer needed to looking
11296 merely by its id: its number.
11298 2001-12-10 Akim Demaille <akim@epita.fr>
11300 * src/LR0.c (augment_automaton): Better variable locality.
11301 Remove an impossible branch: if there is a state corresponding to
11302 the start symbol being shifted, then there is shift for the start
11303 symbol from the initial state.
11305 2001-12-10 Akim Demaille <akim@epita.fr>
11307 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11308 only when appropriate: when insert_start_shifting_state' is not
11310 * tests/regression.at (Rule Line Numbers): Adjust.
11312 2001-12-10 Akim Demaille <akim@epita.fr>
11314 * src/LR0.c (augment_automaton): Now that all states have shifts,
11315 merge the two cases addition shifts to the initial state.
11317 2001-12-10 Akim Demaille <akim@epita.fr>
11319 * src/lalr.c (set_state_table): Move to...
11321 * src/lalr.c (lalr): Don't call it...
11322 * src/LR0.c (generate_states): do it.
11323 * src/LR0.h (first_state): Remove, only the table is used.
11325 2001-12-10 Akim Demaille <akim@epita.fr>
11327 * src/LR0.h (first_shift, first_reduction): Remove.
11328 * src/lalr.c: Don't use first_shift: find shifts through the
11331 2001-12-10 Akim Demaille <akim@epita.fr>
11333 * src/LR0.c: Attach shifts to states as soon as they are
11335 * src/lalr.c (set_state_table): Instead of assigning shifts to
11336 state, just assert that the mapping was properly done.
11338 2001-12-10 Akim Demaille <akim@epita.fr>
11340 * src/LR0.c (insert_start_shift): Rename as...
11341 (insert_start_shifting_state): this.
11342 (insert_eof_shifting_state, insert_accepting_state): New.
11343 (augment_automaton): Adjust.
11344 Better locality of the variables.
11345 When looking if the start_symbol is shifted from the initial
11346 state, using `while (... symbol != start_symbol ...)' sounds
11347 better than `while (... symbol < start_symbol ...)': If fail
11348 to see how the order between symbols could be relevant!
11350 2001-12-10 Akim Demaille <akim@epita.fr>
11352 * src/getargs.h: Don't declare `spec_name_prefix' and
11353 `spec_file_prefix', declared by src/files.h.
11354 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11355 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11356 * src/output.c (prepare): Adjust.
11357 * src/reader.c (symbols_output): Likewise.
11358 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11360 2001-12-10 Akim Demaille <akim@epita.fr>
11362 * src/muscle_tab.c (muscle_init): NULL is a better default than
11365 2001-12-10 Akim Demaille <akim@epita.fr>
11367 * src/reader.c (reader): Calling symbols_output once is enough.
11369 2001-12-10 Akim Demaille <akim@epita.fr>
11371 Now that states have a complete set of members, the linked list of
11372 reductions is useless: just fill directly the state's reductions
11375 * src/state.h (struct reductions): Remove member `number' and
11377 * src/LR0.c (first_reduction, last_reduction): Remove.
11378 (save_reductions): Don't link the new reductions, store them in
11380 * src/lalr.c (set_state_table): No need to attach reductions to
11381 states, it's already done.
11382 * src/output.c (output_actions): No longer free the shifts, then
11383 the reductions, then the states: free all the states and their
11386 2001-12-10 Akim Demaille <akim@epita.fr>
11388 * src/options.c (OPTN, DRTV, BOTH): New.
11389 (option_table): Use them.
11391 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11392 the job of system.h.
11393 * src/options.c: Don't include stdio.h and xalloc.h for the same
11396 2001-12-10 Akim Demaille <akim@epita.fr>
11398 * src/output.c (output, prepare): Make sure the values of the
11399 muscles `action' and `prologue' are 0-terminated.
11401 2001-12-10 Akim Demaille <akim@epita.fr>
11403 Clean up GCC warnings.
11405 * src/reader.c (copy_action): `buf' is not used.
11406 (parse_skel_decl): Be static.
11407 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11408 * src/options.h (create_long_option_table): Have a real prototype.
11409 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11410 (hash_delete_at): Return const void *.
11411 Adjust casts to preserve the const.
11413 2001-12-10 Akim Demaille <akim@epita.fr>
11415 * configure.in: Require 2.52g.
11416 M4 is not needed, but AUTOM4TE is.
11417 * m4/m4.m4: Remove.
11418 * tests/Makefile.am: Adjust.
11420 2001-12-10 Akim Demaille <akim@epita.fr>
11422 One structure for states is enough, even though theoretically
11423 there are LR(0) states and LALR(1) states.
11425 * src/lalr.h (state_t): Remove.
11426 (state_table): Be state_t **, not state_t *.
11427 * src/state.h (core, CORE_ALLOC): Rename as...
11428 (state_t, STATE_ALLOC): this.
11429 Add the LALR(1) members: shifts, reductions, errs.
11430 * src/LR0.c (state_table): Rename as...
11431 (state_hash): this, to avoid name clashes with the global
11433 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11434 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11436 2001-12-10 Akim Demaille <akim@epita.fr>
11438 Bison dumps core on bash.y.
11439 Reported by Pascal Bart.
11441 * src/warshall.c (bitmatrix_print): New.
11443 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11444 j must be the outer loop.
11445 * tests/regression.at (Broken Closure): New.
11447 2001-12-05 Akim Demaille <akim@epita.fr>
11449 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11451 Reported by Peter Hamorsky.
11453 2001-12-05 Akim Demaille <akim@epita.fr>
11455 * src/conflicts.c (err_table): Remove.
11456 (resolve_sr_conflict): Adjust.
11457 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
11459 (state_t.reductions, state_t.shifts): this.
11461 2001-12-05 Akim Demaille <akim@epita.fr>
11463 * src/reduce.c (reduce_grammar_tables): No longer disable the
11464 removal of useless rules via CPP but via `if (0)', so that the
11465 compiler still check the code is valid.
11466 For instance, it should have noticed `rline' no longer exists: use
11467 the `line' member of rule_t.
11468 * src/gram.c (dummy, rline): Remove, unused.
11470 2001-12-05 Akim Demaille <akim@epita.fr>
11472 * src/output.c (pack_vector): Use assert, not berror.
11473 * src/main.c (berror): Remove, unused.
11475 2001-12-05 Akim Demaille <akim@epita.fr>
11477 New experimental feature: if --verbose --trace output all the
11478 items of a state, not only its kernel.
11480 * src/print.c (print_core): If `trace_flag', then invoke closure
11481 before outputting the items of the state (print_core is no longer
11482 a correct name them).
11483 (print_results): Invoke new_closure/free_closure if needed.

11494 (closure): Use it for printing input and output.
11496 2001-12-05 Akim Demaille <akim@epita.fr>
11498 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11499 indexed by nonterminals.
11501 2001-12-05 Akim Demaille <akim@epita.fr>
11503 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

11522 using the good o' techniques: arrays not pointers, variable
11523 locality, BITISSET, RESETBIT etc.
11525 2001-12-05 Akim Demaille <akim@epita.fr>
11527 Pessimize the code to simplify it: from now on, all the states
11528 have a valid SHIFTS, which NSHIFTS is possibly 0.
11530 * src/LR0.c (shifts_new): Be global and move to..
11531 * src/state.c, src/state.h: here.
11532 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

11538 * src/conflicts.c: Use it.
11539 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11540 incorrectly ``simplified''.

11544 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11545 using the good o' techniques: arrays not pointers, variable
11546 locality, BITISSET, RESETBIT etc.
11548 2001-12-05 Akim Demaille <akim@epita.fr>
11550 * src/state.h (SHIFT_SYMBOL): New.

11580 2001-12-05 Akim Demaille <akim@epita.fr>

11599 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11600 * src/lalr.c (build_relations): Adjust.
11602 2001-12-05 Akim Demaille <akim@epita.fr>
11604 * src/lalr.c (transpose): Free the memory allocated to the
11605 argument, as it is replaced by the results by the unique caller.
11606 (build_relations): Merely invoke transpose: it handles the memory
11608 Improve variable locality.
11609 Avoid variables used as mere abbreviations.
11610 (compute_lookaheads): Use arrays instead of pointers.
11612 2001-12-05 Akim Demaille <akim@epita.fr>
11614 * src/lalr.c (initialize_F): Improve variable locality.
11615 Avoid variables used as mere abbreviations.

11630 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11631 the handling of squeue.
11632 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11634 2001-12-05 Akim Demaille <akim@epita.fr>
11636 Because useless nonterminals are now kept alive (instead of being
11637 `destroyed'), we now sometimes examine them, and store information
11638 related to them. Hence we need to know their number, and adjust
11639 memory allocations.
11641 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11643 * src/LR0.c (allocate_itemsets): The memory allocated to
11644 `symbol_count' was used for two different purpose: once to count
11645 the number of occurrences of each symbol, and later reassigned to
11646 `shift_symbol', containing the symbol that can be shifted from a
11648 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11650 (new_itemsets): Allocate `shift_symbol' here.
11651 (allocate_itemsets): symbol_count includes useless nonterminals.
11652 Make room for them.
11653 (free_storage): Use `free', not `XFREE', for pointers that cannot
11656 2001-12-05 Akim Demaille <akim@epita.fr>
11658 * src/nullable.c (set_nullable): Deobfuscate the handling of
11660 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11662 2001-12-05 Akim Demaille <akim@epita.fr>
11664 * src/gram.c, src/gram.h (ritem_print): New.
11665 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
11666 (This useless function was defined only to work around VMS linkers
11667 that can't handle compilation units with variables only).
11668 * src/reduce.c (dump_grammar): Use it to trace the construction of
11671 2001-12-04 Paul Eggert <eggert@twinsun.com>
11673 * src/bison.simple (union yyalloc): Change member names
11674 to be the same as the stack names.
11675 (yyparse): yyptr is now union yyalloc *, not char *.
11676 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
11677 and may generate better code on some machines.
11678 (yystpcpy): Use prototype if __STDC__ is defined, not just
11679 if __cplusplus is defined.
11681 2001-11-30 Akim Demaille <akim@epita.fr>
11683 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
11684 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
11685 Gettext doesn't compile cleanly, and dies with -Werror.
11686 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
11687 Include WARNING_CFLAGS here.
11688 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
11689 before being defined.

11693 * lib/quotearg.h (quotearg_n, quotearg_n_style):
11694 First arg is int, not unsigned.

11696 (SIZE_MAX, UINT_MAX): New macros.
11697 (quotearg_n_options): Abort if N is negative.
11698 Avoid overflow check on hosts where size_t is 64 bits and int
11699 is 32 bits, as overflow is impossible there.
11700 Fix off-by-one typo that caused unnecessary reallocation.
11702 2001-11-29 Paul Eggert <eggert@twinsun.com>
11704 Name space cleanup in generated parser.
11706 * doc/bison.texinfo (Bison Parser): Discuss system headers
11707 and their effect on the user name space.
11709 * src/bison.simple:
11710 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
11711 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
11712 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
11714 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
11715 on user names when possible.
11717 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
11718 Simplify test for whather <alloca.h> exists.
11720 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
11722 (<stdio.h>): Include if YYDEBUG.
11724 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
11725 ! defined (yyoverflow) && ! defined (yymemcpy).
11727 (yymemcpy, yyparse): Rename local variables as needed so that
11728 they all begin with 'yy'.
11730 (yystrlen, yystpcpy): New functions.
11732 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
11735 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
11736 instead of relying on string.h functions. Use YYSTACK_ALLOC
11737 and YYSTACK_FREE instead of malloc and free.
11739 2001-11-30 Akim Demaille <akim@epita.fr>
11741 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
11742 before their first uses.

11752 if body instead of `;' to pacify GCC's warnings.
11754 2001-11-30 Akim Demaille <akim@epita.fr>
11756 Instead of mapping the LHS of unused rules to -1, keep the LHS
11757 valid, but flag the rules as invalid.
11759 * src/gram.h (rule_t): `useful' is a new member.
11760 * src/print.c (print_grammar): Adjust.
11761 * src/derives.c (set_derives): Likewise.
11762 * src/reader.c (packgram, reduce_output): Likewise.
11763 * src/reduce.c (reduce_grammar_tables): Likewise.
11764 * tests/reduce.at (Underivable Rules, Useless Rules): New.

11780 2001-11-30 Akim Demaille <akim@epita.fr>

11790 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
11791 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
11793 (union yyalloc): New type.
11794 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
11795 an arbitrary restriction on hosts where size_t is wider than int.
11797 (yyparse): Don't dump core if alloca or malloc fails; instead, report
11798 a parser stack overflow. Allocate just one block of memory for all
11799 three stacks, instead of allocating three blocks; this typically is
11800 faster and reduces fragmentation.
11802 Do not limit the number of items in the stack to a value that fits
11803 in 'int', as this is an arbitrary limit on hosts with 64-bit
11804 size_t and 32-bit int.
11806 2001-11-29 Marc Autret <autret_m@epita.fr>
11808 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

11859 2001-11-28 Akim Demaille <akim@epita.fr>
11861 * src/closure.c (closure): Instead of looping over word in array
11862 then bits in words, loop over bits in array.
11864 2001-11-28 Akim Demaille <akim@epita.fr>
11866 * src/closure.c (closure): No longer optimize the special case
11867 where all the bits of `ruleset[r]' are set to 0, to make the code
11870 2001-11-28 Akim Demaille <akim@epita.fr>
11872 * src/closure.c (closure): `r' and `c' are new variables, used to

11891 2001-11-27 Paul Eggert <eggert@twinsun.com>
11893 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

12236 use abs. path to find config.h.
12237 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

12263 Be sure to strdup `arg' when used, since there is no reason for
12264 token_buffer not to change.

13609 * src/conflicts.c (conflict_report): Be sure not to append to res
13610 between two calls, which could happen if both first sprintf were

13615 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
13616 New, from fileutils 4.0.37.
13617 * configure.in: Require Autoconf 2.49c. I took some time before
13618 making this decision. This is the only way out for portability
13619 issues in Bison, it would mean way too much duplicate effort to
13620 import in Bison features implemented in 2.49c since 2.13.
13621 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
13623 2001-02-02 Akim Demaille <akim@epita.fr>

13640 * src/lex.h: Rename all the tokens:
13641 s/\bENDFILE\b/tok_eof/g;
13642 s/\bIDENTIFIER\b/tok_identifier/g;
13644 Let them be enums, not #define, to ease debugging.

13663 * src/files.c (open_files): Don't call `compute_base_names', don't

13667 * src/output.c (output_headers): Document the fact that this patch
13668 introduces a guaranteed SEGV for semantic parsers.
13669 * doc/bison.texinfo: Document them.
13670 * tests/suite.at: Exercise these %options.
13672 2000-12-20 Akim Demaille <akim@epita.fr>

13737 (obstack_grow_string): this.
13738 * src/output.c (output_parser): Recognize `%% actions' instead of
13740 * src/bison.s1: s/$/%% actions/.
13741 * src/bison.hairy: Likewise.
13743 2000-12-19 Akim Demaille <akim@epita.fr>
13745 * src/output.c (output_parser): Compute the `#line' lines when
13747 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

13772 * src/files.c (open_files): Yipee! We no longer need all the code

13777 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

13804 * lib/obstack.h: Formatting changes.
13805 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
13806 prevents type checking.

13830 Use them to declare the variables which are global or local to
13833 2000-11-17 Akim Demaille <akim@epita.fr>
13835 * acconfig.h: Remove, no longer used.
13837 2000-11-07 Akim Demaille <akim@epita.fr>
13839 * src: s/Copyright (C)/Copyright/g.
13841 2000-11-07 Akim Demaille <akim@epita.fr>
13843 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
13845 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

13861 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
13862 `const' their input argument (`data' or `address').
13863 Adjust the corresponding macros to include `const' in casts.

13867 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

13875 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

13885 Don't use `atexit'.
13887 * src/files.c (obstack_save): New function.
13888 (done): Rename as...
13889 (output_files): this.
13890 Use `obstack_save'.
13891 * src/main.c (main): Don't use `atexit' to register `done', since
13892 it no longer has to remove tmp files, just call `output_files'
13893 when there are no errors.
13895 2000-11-02 Akim Demaille <akim@epita.fr>
13897 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
13898 `unlink': it's no longer used.
13899 * src/files.h: Formatting changes.
13901 2000-11-02 Akim Demaille <akim@epita.fr>
13903 Remove the last uses of mktemp and unlink/delete.
13905 * src/files.c (fdefines, ftable): Removed.
13906 (defines_ostack, table_obstack): New.
13907 Adjust dependencies of the former into uses of the latter.

13965 * src/reader.c (copy_comment2): Expect the input stream to be on
13966 the `/' which is suspected to open a comment, instead of being
13967 called after `//' or `/*' was read.
13968 (copy_comment, copy_definition, parse_union_decl, copy_action)
13969 (copy_guard): Adjust.
13971 2000-10-16 Akim Demaille <akim@epita.fr>

13979 (copy_guard, copy_action): Use it.
13981 2000-10-16 Akim Demaille <akim@epita.fr>
13983 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
13984 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
13985 New files, from Fileutils 4.0.27.
13986 * src/main.c (printable_version): Remove.

13995 * doc/bison.texinfo: Various typos spotted by Neil Booth.
13997 2000-10-04 Akim Demaille <akim@epita.fr>
13999 When a literal string is used to define two different tokens,
14000 `bison -v' segfaults.
14001 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
14003 * tests/regression.m4: New file.
14004 Include the core of the sample provided by Piotr Gackiewicz.
14005 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
14008 2000-10-04 Akim Demaille <akim@epita.fr>

14028 translation, move some `\n' out of the translated strings.
14030 2000-10-02 Akim Demaille <akim@epita.fr>
14032 The location tracking mechanism is precious for parse error
14033 messages. Nevertheless, it is enabled only when `@n' is used in
14034 the grammar, which is a different issue (you can use it in error
14035 message, but not in the grammar per se). Therefore, there should
14036 be another means to enable it.
14038 * src/getargs.c (getargs): Support `--locations'.
14039 (usage): Report it.
14040 * src/getargs.h (locationsflag): Export it.

14044 * doc/bison.texinfo: Document `--locations' and `%locations'.
14046 * tests/calc.m4: Test it.
14048 For regularity of the names, replace each
14049 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14050 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14051 In addition replace each `flag' with `_flag'.
14053 2000-10-02 Akim Demaille <akim@epita.fr>
14055 Also test parse error messages, including with YYERROR_VERBOSE.
14057 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14059 Use it to check the computations.
14060 Use it to check `nonassoc' is honored.
14061 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14062 `--yyerror-verbose'.
14063 (_AT_CHECK_CALC): Adjust to this option.

14068 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14069 the latter demonstrates a flaw in the handling of non debugging
14070 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14071 was used in order to simplify:
14087 unfortunately this leads to a CPP conflict when
14088 `--name-prefix=foo' is used since it produces `#define yydebug
14091 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14092 (YYDPRINTF): New macro.
14094 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from

14100 Improve the readability of the produced parsers.
14102 * src/bison.s1: Formatting changes.
14103 Improve the comment related to the `$' mark.
14104 (yydefault): Don't fall through to `yyresume': `goto' there.
14105 * src/output.c (output_parser): When the `$' is met, skip the end
14107 New variable, `number_of_dollar_signs', to check there's exactly
14108 one `$' in the parser skeleton.
14110 2000-10-02 Akim Demaille <akim@epita.fr>
14112 * lib/xstrdup.c: New file, from the fileutils.
14113 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14114 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14115 instead of strlen + xmalloc + strcpy.
14116 * src/symtab.c (copys): Remove, use xstrdup instead.
14118 2000-10-02 Akim Demaille <akim@epita.fr>
14120 * src/gram.h (associativity): New enum type which replaces the
14121 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14122 `right_assoc', `left_assoc' and `non_assoc'.
14123 Adjust all dependencies.
14124 * src/reader.c: Formatting changes.
14125 (LTYPESTR): Don't define it, use it as a literal in
14126 `reader_output_yylsp'.
14127 * src/symtab.h (symbol_class): New enum type which replaces the
14128 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14129 `sunknown', `stoken and `snterm'.

14135 Adjust dependencies.
14137 2000-10-02 Akim Demaille <akim@epita.fr>
14139 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14140 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14141 difficult and introduced a lot of core dump. It turns out that
14142 Bison used an implementation of `xmalloc' based on `calloc', and
14143 at various places it does depend upon the initialization to 0. I
14144 have not tried to isolate the pertinent places, and all the former
14145 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14146 someone should address this issue.
14148 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14149 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14243 * src/output.c (token_actions): Introduce a temporary array,
14244 YYDEFACT, that makes it possible for this function to use
14245 output_short_table.
14247 2000-10-02 Akim Demaille <akim@epita.fr>
14249 `user_toknums' is output as a `short[]' in `output.c', while it is
14250 defined as a `int[]' in `reader.c'. For consistency with the
14251 other output tables, `user_toknums' is now defined as a table of

14294 Don't define PARAMS.
14295 * src/system.h: Define PARAMS.
14296 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
14297 purpose of config.h. system.h must not try to fix wrong

14514 2000-03-17 Akim Demaille <akim@epita.fr>
14516 Change the handling of @s so that they behave exactly like $s.
14517 There is now a pseudo variable @$ (readble and writable), location
14518 of the lhs of the rule (by default ranging from the location of
14519 the first symbol of the rhs, to the location of the last symbol,
14520 or, if the rhs is empty, YYLLOC).
14522 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
14524 (yyparse): When providing a default semantic action, provide a
14525 default location action.
14526 (after the $): No longer change `*YYLSP', just stack YYLOC the
14527 same way you stack YYVAL.
14528 * src/reader.c (read_declarations): Use warns.
14529 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
14530 (copy_action, case '@'): Likewise.

14555 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
14556 One `#if YYDEBUG' remains, since it uses variables which are
14557 defined only if `YYDEBUG != 0'.

14581 Bump to bison 1.28a, 1.29 has never been released.
14582 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
14583 handled via src/Makefile.am.

15221 New #define for adding aliases to %token.
15222 (struct bucket): Added `alias' field.
15224 * src/reduce.c (reduce_grammar):
15225 Revise error message.
15226 (print_notices): Remove final `.' from error message.
15228 * src/reader.c (reader_output_yylsp):
15230 (readgram): Use `#if 0' around code that accepted %command
15231 inside grammar rules: The documentation doesn't allow it,
15232 and it will fail since the %command processors scan for the next %.
15233 (parse_token_decl): Extended the %token
15234 declaration to allow a multi-character symbol as an alias.
15235 (parse_thong_decl): New function.
15236 (read_declarations): Added %thong declarations.
15237 (read_declarations): Handle NOOP to deal with allowing
15238 % declarations as another means to specify the flags.
15239 (readgram): Allow %prec prior to semantics embedded in a rule.
15240 (skip_to_char, read_declarations, copy_definition)
15241 (parse_token_decl, parse_start_decl, parse_type_decl)
15242 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
15243 (get_type_name, copy_guard, copy_action, readgram)
15244 (get_type, packsymbols): Revised most error messages.
15245 Changed `fatal' to `warnxxx' to avoid aborting for error.
15246 Revised and use multiple warnxxx functions to avoid using VARARGS1.
15247 (read_declarations): Improve the error message for
15248 an invalid character. Do not abort.
15249 (read_declarations, copy_guard, copy_action): Use
15250 printable_version to avoid unprintable characters in printed output.
15251 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
15252 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
15253 Allow the type of a non-terminal can be given
15254 more than once, as long as all specifications give the same type.
15257 (output_headers, output_trailers, output, output_gram)
15258 (output_rule_data): Implement noparserflag variable.
15259 Implement toknumflag variable.
15260 (output): Call reader_output_yylsp to output LTYPESTR.
15262 * src/main.c (main):
15263 If reader sees an error, don't process the grammar.
15264 (fatals): Updated to not use VARARGS1.
15265 (printable_version, int_to_string, warn, warni, warns, warnss)
15266 (warnsss): New error reporting functions. Avoid abort for error.
15269 Added THONG and NOOP for alias processing.
15270 Added SETOPT for the new code that allows setting options with %flags.
15273 Include getopt.h. Add some extern decls.
15274 (safegetc): New function to deal with EOF gracefully.
15275 (literalchar); new function to deal with reading \ escapes.
15276 (lex): Use literalchar.
15277 (lex): Implemented "..." tokens.
15278 (literalchar, lex, parse_percent_token): Made tokenbuffer
15279 always contain the token. This includes growing the token
15280 buffer while reading an integer.
15281 (parse_percent_token): Replaced if-else statement with percent_table.
15282 (parse_percent_token): Added % declarations as another
15283 way to specify the flags -n, -l, and -r. Also added hooks for
15284 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
15285 major changes to files.c.
15286 (lex) Retain in the incoming stream a character following
15288 (skip_white_space, lex): Revised most error messages
15289 and changed fatal to warn to avoid aborting.
15290 (percent_table): Added %thong declarations.
15292 * src/gram.h: Comment changes.
15294 * src/files.c (openfiles, open_extra_files, done):
15296 and actfile file. Handle noparserflag. Both for -n switch.
15298 * src/conflicts.c (resolve_sr_conflict):
15299 Remove use of alloca.
