MVT is cheaper than EVT and conceptually cleaner when dealing with physical machine types. EVT should only be used in parts of the code generator that are "pre-legalization" because they can represent arbitrary IR types. Anything that takes a legal machine type should take an MVT.</div><div><br></div><div>-Chris</div><br></body></html>
