According to v-spec (section 5.4): When vstart ≥ vl, there are no body elements, and no elements are updated in any destination vector register group, including that no tail elements are updated with agnostic values. vmsbf.m, vmsif.m, vmsof.m, viota.m, vcompress instructions themselves require vstart to be zero.
