+
+ * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
+ YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.

+
+2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>

+ (yy::b4_parser_class_name): Declare instance variables to
+ hold parse-param arguments.
+ * tests/calc.at: s/value/semantic_value/ because value clashes
+ with a member of yy::b4_parser_class_name. Adjust C++ code
+ to handle %parse-param. Enable %parse-param test in C++.
+
+2003-05-12 Paul Eggert <eggert@twinsun.com>
+
+ * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
+ English a bit. Fix fclose typo. Change "const char" to "char
+ const", and use ANSI C rather than K&R for "main". Suggest
+ YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
+ and suggest yy_switch_to_buffer.
+
+2003-05-05 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
+ C89. This avoids a diagnostic on compilers that define __STDC__
+ to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-05-03 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
+ Do not overrun array bounds.
+ This should fix a bug reported today by Olatunji Oluwabukunmi in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
+ * src/getargs.c, src/getargs.h: here, as bool, not int.
+ (nondeterministic_parser): New.
+ * src/parse-gram.y, src/scan-gram.l: Support
+ %nondeterministic-parser.
+ * src/output.c (prepare): Use nondeterministic_parser instead

+ * src/tables.c (conflict_row, action_row, save_row)
+ (token_actions, token_actions, pack_vector): Ditto.
+
+2003-04-29 Akim Demaille <akim@epita.fr>

+ with %pure-parser and %locations to exercise the patch from Yakov
+ Markovitch below.
+
+2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * data/yacc.c: (b4_lex_param): Corrected for the case where
+ %lex-param is provided and %pure-parser isn't.
+
+2003-04-27 Paul Eggert <eggert@twinsun.com>
+
+ Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.

+ if it is not defined.
+ (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
+
+2003-04-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+ Declare to be of type suitable for the ninf value itself, not of
+ type suitable for the corresponding table, since the latter might
+ be unsigned but the ninf value might be negative. This fixes a
+ bug reported by Alexandre Duret-Lutz in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+ * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+ invokes it. We shouldn't invoke it twice because it will attempt
+ to put error.o in the archive twice. This fixes a glitch reported
+ by Martin Mokrejs in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21 Paul Eggert <eggert@twinsun.com>
+
+ * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
+ to gnulib.
+
+2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
+
+ * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+ Fix obvious typo that results in uncompilable GLR parsers
+ when both %pure-parser and %locations are used. (trivial change)
+
+2003-04-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+ (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+ Do not insert the expected token via unput, as this runs afoul
+ of a POSIX-compatibility bug in flex 2.5.31.
+ All uses changed to BEGIN the parent state,
+ since we no longer insert the expected token via unput.
+ * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+ that is no longer emitted after the above change.
+
+ * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+ the first one. This change is from Paul Hilfinger, and it fixes
+ regression reported by Werner Lemberg in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+ (resolve_sr_conflict): Don't invoke state_errs_set
+ unless one or more tokens have been explicitly made errors.
+ Otherwise, the above change causes Bison to abort.
+
+ * tests/existing.at (GNU pic Grammar): New test case, taken from
+ Lemberg's email.
+
+2003-03-31 Akim Demaille <akim@epita.fr>

+ output.
+
+2003-03-31 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
+ From Paul Hilfinger.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * m4/error.m4: Do not put under dynamic conditions some code which
+ expansion is under static control.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Strings are Destroyed): New.
+
+2003-03-13 Paul Eggert <eggert@twinsun.com>
+
+ * .cvsignore: Add configure.lineno.
+ * src/.cvsignore: Add yacc.
+ * tests/.cvsignore: Add testsuite.log.
+ * doc/fdl.texi: Sync with latest FSF version.
+
+2003-03-12 Paul Eggert <eggert@twinsun.com>
+
+ * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+ (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+ cursor, instead of leaving it undefined. This fixes a bug
+ reported by Tim Van Holder in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+ * tests/input.at (Torturing the Scanner): Test the scanner on
+ an empty input file, which was Tim Van Holder's test case.
+
+ * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+ <sys/resource.h> can be included, include sys/time.h and
+ sys/times.h first, if available. This works around the SunOS
+ 4.1.4 porting bug reported by Bruce Becker in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+ * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+ AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+ AC_HEADER_SYS_WAIT.
+
+ Merge changes from gnulib. This was prompted because the CVS
+ snapshot didn't build on Solaris 7 due to strnlen problems.
+
+ These changes need to be merged back into gnulib:
+ * lib/hash.c: Include <stdbool.h> unconditionally.
+ * m4/onceonly.m4 (m4_quote): New macro.
+ (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

+
+ * src/system.h: Include <stdbool.h> unconditionally.
+
+ * lib/bbitset.h: Include <limits.h> unconditionally. We have been
+ assuming at least C89 in the bitset code for some time now.
+
+2003-03-03 Akim Demaille <akim@epita.fr>
+
+ * ro.po: New.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Table of Symbols): Reactivate the
+ documentation for %lex-param, and %parse-param.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
+ generate verbose error messages.
+ Use the number of tokens as an upper bound in yytname, as it
+ cannot be a non terminal.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
+ message.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
+ Use them to exercise yycheck overrun.
+ Based on Andrew Suffield's grammar.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ Create tests/local.at for Bison generic testing macros.
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
+ * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
+ This new file.
+ * tests/calc.at (AT_CHECK_CALC): Adjust.
+ * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
+ (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...

+ (AT_COMPILE_CXX): Tags the tests using it as c++.
+ Ignore the test if CXX is not functional.
+
+2003-03-01 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+ not loc->end, since loc->end might contain garbage and this leads
+ to undefined behavior on some platforms.
+ (id_loc, token_start): Use (IF_LINTed) initial values that do not
+ depend on *loc, so that the reader doesn't give the the false
+ impression that *loc is initialized.
+ (<INITIAL>"%%"): Do not bother setting code_start, since its value
+ does not survive the return.
+
+2003-03-01 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l (code_start): Always initialize it when entering
+ into yylex, as SC_EPILOGUE is activated *before* the corresponding
+ yylex invocation. An alternative would be making it static, but
+ then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28 Paul Eggert <eggert@twinsun.com>
+
+ * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
+ around a UnixWare 7.1.1 porting bug reported by John Hughes in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
+
+2003-02-26 Paul Eggert <eggert@twinsun.com>
+
+ * README: Mention compiler bug in Sun Forte Developer 6 update 2.
+ Remove Sequent/Pyramid discussion (nobody uses them any more).
+ Merge VMS and MS-DOS discussion; these ports may well be dead
+ but let's keep mentioning them for now. Put <> around email
+ addresses. Add copyright notice.
+
+2003-02-24 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yy_reduce_print): yylineno -> yylno,

+ Suggested by Paul Eggert.
+
+2003-02-21 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Use "location" consistently to refer to @n,

+ Suggested by Paul Eggert.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): Make sure "columns" never pushes
+ before initial_columns.
+ (location.hh): Use consistent variable names when defining the
+ operator<<.
+ Use "last" so that we subtract from Positions, not from unsigned.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): New subfile, including the extended
+ and Doxygen'ed documentation of class Position.
+ (location.hh): Use it.
+ Document a` la Doxygen.
+ With the help of Benoit Perrot.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
+ AT_YACC_IF.
+ Redefine AT_YYERROR_SEES_LOC_IF using it.
+ (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
+ not defined.
+ Don't use the location in yy::Parser::error_ and
+ yy::Parser::print_ when not %locations.
+ Activate more lalr1.cc tests.
+
+2003-02-19 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: When displaying a line number, be sure to make it
+ an int.
+
+2003-02-19 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
+ Remove, useless.
+ (YYABORT, YYACCEPT, YYERROR): New.
+ * tests/calc.at: Renable the lalr1.cc test.
+
+2003-02-19 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
+ error recovery, mixing with/without pops and discarding of the
+ lookahead.
+ Exercise YYERROR.
+ Disable the lalr1.cc tests as currently it doesn't support YYERROR.
+
+2003-02-17 Paul Eggert <eggert@twinsun.com>
+
+ * tests/atlocal.in (LDFLAGS, LIBS): New vars.
+ * tests/testsuite.at (AT_COMPILE): Use them.
+ This fixes the testsuite problem reported by Robert Lentz in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
+
+2003-02-12 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
+ Avoid subscript error in yycheck. Bug reported by Andrew Suffield in

+ * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
+ Check for malloc failure, for consistency with yacc.c.
+ (yytname_size): Remove, for consistency with yacc.c.
+
+ The bug still remains in data/lalr1.cc, as I didn't have time
+ to fix it there.
+
+2003-02-06 Akim Demaille <akim@epita.fr>
+
+ * configure.ac (GXX): Rename as...
+ (CXX): this, to keep the original Autoconf semantics.

+ * tests/testsuite.at (AT_COMPILE_CXX): New.
+ * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the

+ Conform to the GCS: simplify the locations when applicable.
+ (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
+ (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
