      Description

        The Zero routine for atomic_copy64 should use the same as is done for JDK 7. JDK 7 Zero maintained at IcedTea uses ldrexd for atomic reads on ARMv7:

        https://icedtea.classpath.org/hg/icedtea7-forest/hotspot/rev/b0a871360c6b

        The Zero port in latest JDK should use the same.
