Hi,
[PATCH, rs6000] (v2) Testcase coverage for vec_perm built-ins
Add some Testcase coverage for the vector permute intrinsics.
(v2) Revisited and reworked all of the requires statements
throughout this batch. Everything specifies -maltivec except
the double and long long tests, which require vsx.
(re-) Tested across power platforms. OK for trunk?
Thanks,
-Will
