(rs6000_builtin_mask_for_load): Return 0 for targets with efficient unaligned VSX accesses so that the vectorizer will use direct unaligned loads. (rs6000_builtin_support_vector_misalignment): Always return true for targets with efficient unaligned VSX accesses. (rs6000_builtin_vectorization_cost): Cost of unaligned loads and stores on targets with efficient unaligned VSX accesses is almost always the same as the cost of an aligned load or store, so model it that way. * config/rs6000/rs6000.h (SLOW_UNALIGNED_ACCESS): Return 0 for unaligned vectors if we have efficient unaligned VSX accesses. * config/rs6000/rs6000.opt (mefficient-unaligned-vector): New undocumented option.
