Subject: opaque vector types?
Date: Wed, 06 May 2009 06:04:00 -0000 [thread overview]
Message-ID: <200905060604.n4664Skm024765@greed.delorie.com> (raw)
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.
