        Description

        in fast_xaccess,
           case itos:
                __ ldr(r0, Address(r0, r1, Address::lsl(0)));

        This is a full xword load but it should be a halfword.

        Also,

            __ membar(MacroAssembler::LoadLoad);

        should be LoadLoad | LoadStore.
