Vector pair odd

This instruction is defined by:

Encoding

Synopsis

Interleaves odd-indexed elements of two source vector register groups into the destination. All operands have EMUL=LMUL. For destination index i, even indices read vs2[i+1] and odd indices read vs1[i], producing [vs2[1], vs1[1], vs2[3], vs1[3], …​]. When vl is odd, the final out-of-range source position contributes zero; no source at or above vl is read. Standard vector masking, prestart, inactive, and tail handling applies. The destination may not overlap either source group.
