Hi Stefan,
due to that missed optimization we currently generate silly code for these two
tests and should
really fix this (after gcc entering stage1). So just skipping it on s390x would
definitely be the
wrong choice I think.
I think our vectorize_vec_perm_const correctly rejects this permute
The tests fail on s390 since can_vec_perm_const_p fails and therefore
the bit insert/ref survive which r14-3381-g27de9aa152141e aims for.
Strictly speaking, the tests only fail in case the target supports
vectors, i.e., for targets prior z13 or in case of -mesa the emulated
vector operations are
