; FIXME: For the "_n" multiply/multiply-accumulate insns, we copy a value in a
; core register into a temp register, then use a scalar taken from that. This
; isn't an optimal solution if e.g. the scalar has just been read from memory
; or extracted from another vector. The latter case it's currently better to
; use the "_lane" variant, and the former case can probably be implemented
; using vld1_lane, but that hasn't been done yet.
