--- Comment #5 from Andrew Waterman <andrew at sifive dot com> ---
FWIW, it _is_ an improvement on SiFive's in-order vector units--but only under
the assumption that the values of vtype and vl were don't-cares, so that we
won't end up needing to execute yet another vsetvli to restore them to their
previous value. Jeff's of course right that this doesn't hold for all uarches,
especially those that need to allocate new physical registers for vtype/vl.
