+                    (vec.vt (bitconvert V128:$lhs))),
----------------
Sorry I asked this in person yesterday, but I don't think I quiet got it; why is this only for the ordered comparison? And does pseudo-min/max mean non-NaN-propagating?

+def : Pat<(vec.int_vt (vselect
+            (setolt (vec.vt (bitconvert V128:$lhs)),
+                    (vec.vt (bitconvert V128:$rhs))),
+            V128:$rhs, V128:$lhs)),
+          (pmax $lhs, $rhs)>;
----------------
Is it OK to change the return type? The source pattern's return type is an int vector but the resulting instruction's type is a float vector.
