      Description

        The arraycopy_prologue method and decendents in hotspot/cpu/aarch64/gc/g1/shared/barrierSetAssembler_aarch64.hpp only accepts the destination array. For implementing read barriers, it also needs to be passed the source array, and the GC implementation then should use the most appropriate one.
