Paul Eggert 907e3bc851 (AT_CHECK_CALC): New option EXPECTED-TO-FAIL. 
(AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
the tests right now.
 2003-06-16 18:42:49 +00:00
Paul Eggert b8a204c09b (_AT_TEST_GLR_CXXTYPES): Ensure yylex and 
yyerror are declared before use; C99 requires this.

Paul Eggert 711f40b715 Avoid warnings generated by GCC 2.95.4 when Bison is 
configured with --enable-gcc-warnings.
 2003-06-04 05:58:52 +00:00
Paul Eggert 848dc439cb (_AT_DATA_DANCER_Y): Declare yylex to take 
(void) as arg when not pure, since we now assume C89 when building
Bison.  Pacify GCC by using parameter.
 2003-06-04 05:54:16 +00:00
Paul Eggert f56f6d78b0 (Improper handling of embedded actions and $-N in GLR parsers): Remove 
unused local variable from yylex.

Paul Eggert ac695f7df5 * data/lalr1.cc (yy::Position::lines, yy::Position::columns, 
yy::Location::lines, yy::Location::columns): Rename arguments
to avoid shadowing; this removes a warning generated by GCC 3.3.

Paul Eggert 2ffbee0e0b (yy::Position::lines, yy::Position::columns, 
yy::Location::lines, yy::Location::columns): Rename arguments

 2003-06-02 08:19:08 +00:00
Paul Eggert 26ec81e097 Don't pass C-only options to g++. 
Fix YYFILL in GLR parsers to conform to the C standard.
Fix infinite loops in yacc.c, and add a test case.
 2003-06-02 07:29:18 +00:00
Paul Eggert 57f5199797 (AT_COMPILE_CXX): Use it instead of CFLAGS. 2003-06-02 07:26:17 +00:00
Paul Eggert 713535c232 (CXXFLAGS): New var. 2003-06-02 07:25:54 +00:00
Paul Eggert 504f20f77e (WARNING_CXXFLAGS): New subst. Set it to 
everything that WARNING_CFLAGS has, except omit warnings
not suitable for C++.
(AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
 2003-06-02 07:25:30 +00:00
Paul Eggert 6a84279cb5 (yyfillin): Renamed from the old yyfill. Mark 
as possibly unused.
(yyfill): New function.
(YYFILL): Use it.
(yyuserAction): Change type of yynormal to bool, so that it matches
the new yyfill signature.  Mark it as possibly unused.
 2003-06-02 06:18:31 +00:00
Paul Eggert 82c53be476 (_AT_DATA_CALC_Y): Include unistd.h if available. 
Define 'alarm' to do nothing if unistd.h is not available.
Add a new rule "exp: '-' error;" to test the above change to
data/yacc.c.  Use 'alarm' to abort any test taking longer than
10 seconds, as it's probably looping.
(AT_CHECK_CALC): Test recovery from error in new grammar rule.
Also, the new yacc.c generates two fewer diagnostics for an
existing test.
 2003-06-02 03:58:34 +00:00
Paul Eggert a6b89bb2dc (YYERROR): Now just 'goto yyerrorlab', since the 
macro's size was becoming unwieldy.
(yyerrlab): Do not discard an empty lookahead symbol, as this
might destroy garbage.
(yyerrorlab): New label, with the old contents of YYERROR,
plus the following change: pop the stack of rhs corresponding
to the production that invoked YYERROR.  That is how Yacc
behaves, and POSIX requires this behavior.
(yyerrlab1): Use YYPOPSTACK instead of its definiens.

Paul Eggert 3ab370773d * doc/bison.texinfo (How Can I Reset @code{yyparse}): 
Minor English and technical fixups.
 2003-05-12 19:35:13 +00:00
Paul Eggert 0e14ad772f (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.

Paul Eggert 163ab32161 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes C89. 2003-05-05 20:39:42 +00:00
Paul Eggert cfbb7304d8 (__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>.

Paul Eggert 3470c57bea * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):

 2003-04-27 05:57:13 +00:00
Paul Eggert 0c3c1f98ec (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>.

Paul Eggert b59d8a44df (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>.

Paul Eggert 1b8f2fff2a Don't invoke unput from scan-gram.l; it ran into a POSIX-compatibility 
bug in flex 2.5.31.
 2003-04-18 07:27:15 +00:00
Paul Eggert 47e7600a21 (Invalid inputs): Remove cascaded diagnostic that is no longer emitted. 2003-04-18 07:26:46 +00:00
Paul Eggert aa4180418f 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.

 2003-04-18 05:10:58 +00:00
Paul Eggert 0de45ae542 (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.

reported by Tim Van Holder in

Paul Eggert a93df6bad3 (BISON_PREREQ_TIMEVAR): When checking whether <sys/resource.h> can be

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>.
 2003-03-13 00:25:33 +00:00
Paul Eggert 8012adae7b (BISON_PREREQ_SUBPIPE): Don't AC_CHECK_HEADERS([sys/wait.h]), as this

Paul Eggert a2bc9dbc7b (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.
