--- Comment #7 from Janis Johnson <janis at gcc dot gnu.org> 2012-09-26 21:51:53 UTC --- I've tried requiring arm_little_endian for various vect_ effective targets, but the missing support isn't at all clear-cut. Lots of vectorization takes place so it's important to continue to pay attention to the execute tests, but for now I think we'll just handle big-endian expected failures locally.
