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.

Paul Eggert 5ededac618 Fix regression reported by Werner Lemberg in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.

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

(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.

Paul Eggert 69363a9e4d * NEWS: %expect-violations are now just warnings, reverting

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.

that the warning is enabled if the number of conflicts changes
(not necessarily increases).

resurrects the 2001-12-15 patch to src/reader.c.
 2002-12-30 22:40:52 +00:00
