 Fields:
 
 * **sz / dz**  if predication is enabled will put zeros into the dest (or as src in the case of twin pred) when the predicate bit is zero.  otherwise the element is ignored or skipped, depending on context.
+* **zz**: both sz and dz are set equal to this flag
 * **inv CR bit** just as in branches (BO) these bits allow testing of a CR bit and whether it is set (inv=0) or unset (inv=1)
 * **RG** inverts the Vector Loop order (VL-1 downto 0) rather
 than the normal 0..VL-1
