SNP is there from znver3. We earlier planned to add some intrinsics. Then decided that these instructions will be system instructions so will be just asm. May be if we decide to add those intrinsics in future, we will have the predicate then. At present, I will not be adding the intrinsics. For znver3, we initially had the predicate as placeholder and then removed it as the intrinsics weren't there.
