Hi,
GCC should be able to vectorize gcc.dg/vect/pr56541.c on targets do not support
vect_cond_mixed. Problem is jump threading factors comparison out of cond_expr
and creates mixed-type cond_expr. As a result, it can only be vectorized with
vect_cond_mixed. We don't have a good solution at the moment, this patch xfail
it on such targets.
Thanks,
