      Description

      When I implement a new match under MIPS64 and Loongarch64architecture

      match(Set dst (CMoveP (Binary cop (CmpP op1 zero)) (Binary dst zero)));

      this means right child of CmpP is immediate zero and right child of CmovP also is immediate zero, then an exception will occur:
