    Description

      The arraycopy stubs today use AS_RAW accesses, when copying arrays. This is only okay because surrounding "bulk" barriers are applied. Generational ZGC does not have such bulk barriers, and therefore needs to apply barriers directly where the accesses happen. This CR aims at addressing the required interfacing for that.
