Paul Eggert 2175bfbd09 (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>.

Paul Eggert a1c84f4523 Omit spaces around "---". 2003-04-29 18:53:33 +00:00
Paul Eggert 6175ffe321 * data/yacc.c: (b4_lex_param): Corrected for the case where 
%lex-param is provided and %pure-parser isn't.
 2003-04-29 06:04:56 +00:00
Paul Eggert 68cdf74747 (b4_lex_param): Corrected for the case where %lex-param is provided

Paul Eggert b929851a33 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.

Paul Eggert 3470c57bea * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_): 
Declare to be of type suitable for the ninf value itself.
 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>.
 2003-04-27 05:56:34 +00:00
Paul Eggert acda9df6f9 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR invokes it. 2003-04-27 05:28:21 +00:00
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>.
 2003-04-27 05:27:15 +00:00
Paul Eggert b5250f2635 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch to gnulib. 2003-04-22 03:33:29 +00:00

Paul Eggert 089ac0f11c * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: 
Fix obvious typo that results in uncompilable GLR parsers
when both %pure-parser and %locations are used.  (trivial change)
 2003-04-21 19:37:40 +00:00
Paul Eggert 1d2d7eddf7 (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: 
Fix obvious typo that results in uncompilable GLR parsers
when both %pure-parser and %locations are used.  (trivial change
from Yakov Markovitch <[email protected]>)
 2003-04-21 19:37:09 +00:00
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 07:26:19 +00:00
Paul Eggert 5ededac618 Fix regression reported by Werner Lemberg in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
 2003-04-18 05:11:25 +00:00
Paul Eggert 2740f1691f (GNU pic Grammar): New test case, taken from 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
 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.

Paul Eggert 537636c7e5 Fix "Bison blows chunks on empty file" bug. 
Work around SunOS 4.1.4 porting problem with <sys/resource.h>.
Don't check for sys/wait.h twice, with two different algorithms.
 2003-03-13 07:13:05 +00:00
Paul Eggert 379f0ac840 (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>.
 2003-03-13 07:07:17 +00:00

Paul Eggert 0baf7c50ed (Torturing the Scanner): Test the scanner on 
an empty input file, which was Tim Van Holder's test case.
 2003-03-13 07:03:17 +00:00
Paul Eggert a93df6bad3 (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>.
 2003-03-13 00:25:33 +00:00
Paul Eggert 8012adae7b (BISON_PREREQ_SUBPIPE): Don't AC_CHECK_HEADERS([sys/wait.h]), as this 
interferes with AC_HEADER_SYS_WAIT.
 2003-03-13 00:01:07 +00:00
Paul Eggert f61aad9399 Merge changes from gnulib. This was prompted because the CVS 
snapshot of Bison didn't build on Solaris 7 due to strnlen problems.
 2003-03-12 23:08:11 +00:00
Paul Eggert 4f8a9f6dba Include <limits.h> unconditionally. We have been 
assuming at least C89 in the bitset code for some time now.
 2003-03-12 23:01:22 +00:00

Paul Eggert 9c2b381f79 Minor improvements to today's scan-gram.l bugfix. 2003-03-02 06:56:06 +00:00
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.
 2003-03-02 06:55:15 +00:00
Paul Eggert b305ea6918 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work

but let's keep mentioning them for now.  Put <> around email

(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.

and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
 2003-01-29 06:31:02 +00:00
Paul Eggert b2a836b51e * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that 
we don't need to worry about yyerrlab1 being reported as an
"unused label" by non-GCC C compilers.
 2003-01-22 06:39:16 +00:00
Paul Eggert 8a3eb3c8ba (YYERROR): Move code from yyerrlab1 to here, so that 
we don't need to worry about yyerrlab1 being reported as an
"unused label" by non-GCC C compilers.  The downside is that if
locations are used then a couple of statements are duplicated each
time YYERROR is invoked, but the upside is that the warnings
should vanish.
(yyerrlab1): Move code to YERROR.
(yyerrlab2): Remove.  Change uses back to yyerrlab1.
This reverts some of the 2002-12-27 change.

 2003-01-13 07:19:17 +00:00
Paul Eggert 69363a9e4d * NEWS: %expect-violations are now just warnings, reverting 
to Bison 1.30 and 1.75 behavior.  This fixes the GCC 3.2
bootstrapping problem reported by Matthias Klose; see
<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
* src/conflicts.c (conflicts_print): Likewise.
* tests/conflicts.at (%expect not enough, %expect too much,
%expect with reduce conflicts): Likewise.
* doc/bison.texinfo (Expect Decl): Document this.  Also mention
that the warning is enabled if the number of conflicts changes
(not necessarily increases).
 2003-01-13 06:41:29 +00:00

 2003-01-05 01:07:13 +00:00
Paul Eggert 49b6b48b99 (yyerrlab1): Omit attribute if __cplusplus is defined, 
since GNU C++ (as of 3.2.1) does not allow attributes on labels.
Problem reported by Nelson H. F. Beebe.
 2003-01-05 00:48:16 +00:00
Paul Eggert 2f10a596a7 (__INT_TO_PTR) [__STDC__]: Cast result to 
(void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
when compiling Bison 1.875's `bitset bset = obstack_alloc
