Is there an opaque vector type? Something that can be assigned to/from other vector types of the same size, without warning?
I'm working on a coprocessor which has separate SIMD arithmetic operations for each data size, but only one SIMD logical operation for all sizes. I.e. there's four ADD insns (V8QI, V4HI, etc) , but only one AND insn. I'd like to use an opaque vector type for the AND builtin, to avoid warnings.
