--- Comment #6 from Janis Johnson <janis at gcc dot gnu.org> 2012-09-26 16:45:25 UTC --- It's important to continue to run the vectorization tests with ARM big-endian to detect regressions in the execution tests, so I don't want to exclude it from all vect effective targets. I'll propose a set of effective targets used in the scans that should exclude ARM big-endian.
