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)

1b8f2fff2a Don't invoke unput from scan-gram.l; it ran into a POSIX-compatibility 
bug in flex 2.5.31.

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.

2740f1691f (GNU pic Grammar): New test case, taken from 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.

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.

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>.

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

8012adae7b (BISON_PREREQ_SUBPIPE): Don't AC_CHECK_HEADERS([sys/wait.h]), as this 
interferes with AC_HEADER_SYS_WAIT.

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

4f8a9f6dba Include <limits.h> unconditionally. We have been 
assuming at least C89 in the bitset code for some time now.

documentation for %lex-param, and %parse-param.

Akim Demaille
c47495657b * 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 13:39:44 +00:00

22e304a6da Write a test the yycheck overrun reported by Andrew Suffield. 
* tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
Use them to exercise yycheck overrun.
Based on Andrew Suffield's grammar.

* 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...
* tests/local.at: here.
(AT_COMPILE_CXX): Tags the tests using it as c++.
Ignore the test if CXX is not functional.

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
Akim Demaille
0433ba88f9 * 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.
