--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It looks like SPARC should support vec_perm with VIS2, but it's not clear
whether that's enabled. The testcases definitely lack an effective target
check for the required permute which is a whole vector shift by 1 element
plus the insert of the topmost lane into the first or a two-vector shift
by 1 element.
I've checked and
/* { dg-require-effective-target vect_perm } */
should disable the test for sparc but it's not exactly spot-on I think
(and as said, it looks like -mvis2 should suppport the test)
