(define_insn "arm_atomic_loaddi2_ldrd"
  [(set (match_operand:DI 0 "register_operand" "=r")
        (unspec_volatile:DI
          [(match_operand:DI 1 "memory_operand" "m")]
            VUNSPEC_LDRD_ATOMIC))]
  "ARM_DOUBLEWORD_ALIGN && TARGET_HAVE_LPAE"
  "ldrd\t%0, %H0, %1"
)


Maybe "=r" needs to be "=&r" but I could be wrong.
