Yet, just as before, all other options are still provided, right the way back to the pure-scalar case, as if this were a straight OpenPOWER v3.0B non-augmented instruction. -Predication therefore provides several modes traditionally seen in Vector ISAs, particularly if the predicate may be set conveniently as a single bit: this gives VINSERT (VINDEX) behaviour.

VSPLAT (result broadcasting) is provided by making the sources scalar and the destination a vector. VSELECT is provided by setting up (at least one of) the sources as a vector, using a single bit in olthe predicate, and the destination as a scalar. # Predicate "zeroing" mode
