Hello,
this patch fixes the issue reported in PR/48984. Issue is that
fortran has multiple BOOLEAN_TYPE'ed types with different modes. So
the check for BOOLEAN_TYPE in gimplification is wrong and instead we
need to check for identify to boolean_type_node.
ChangeLog
2011-05-13 Kai Tietz
* gimplify.c (gimplify_expr): Check for boolean_type_node instead
for BOOLEAN_TYPE for TRUTH-NOT/AND/OR/XOR.
(gimple_boolify): Check for cast for boolean_type_node instead for
BOOLEAN_TYPE.
Bootstrap passed and now doing fortran testsuite run to verify.
Regards,
Kai
