So if the mask means `xor`, please see above explanation: If the mask is the result of XorVMask ... The backend match rule of `andNot` cannot be matched because its child `XorV` is multi-used. For this case, the `maskAll` should not be cloned to avoid duplicated machnodes generated. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/30013#discussion_r2978596201
