      Description

        Original issue JDK-8226721 adds intrinsics for x86.

        It looks like someone should add similar intrinsics for aarch64. There may need to be a few special case checks, but at first glance this looks like simple intrinsics around an aarch64 instruction (perhaps using FRINTM, FRINTN, FRINTP).
