Target Milestone: ---
Target: s390x
Compiling reduced testcase gcc.target/s390/vector/reverse-elements-6.c with
s390x cross compiler results in ICE since r14-3381-g27de9aa152141e.
$ cat reverse-elements-6.c
typedef long __attribute__((vector_size(16))) V2DI;
V2DI v2di_x;
void v2di() {
V2DI y, z;
for (int i = 0; i < 2; ++i)
z[i] = y[1];
v2di_x = z;
}
$ s390x-linux-gnu-gcc reverse-elements-6.c -O1

So we're getting TImode vectors here for some reason (uninit?).
The VEC_PERM is

tree-optimization/112990 - unsupported VEC_PERM from match pattern
The following avoids creating an unsupported VEC_PERM after vector
lowering from the pattern merging a bit-insert from a bit-field-ref
to a VEC_PERM. For the already existing s390 testcase we get
TImode vectors which later ICE during attempted expansion of
a vec_perm_const.
PR tree-optimization/112990
* match.pd (bit_insert @0 (BIT_FIELD_REF @1 ..) ..):
Restrict to vector modes after lowering.
