So the problem with the stores here is that the base is arg_pointer_rtx which
is still a frame pointer related offset. I think the same can be said is true
of stack_pointer_rtx too. We only set frame_related for frame_pointer_rtx and
hard_frame_pointer_rtx but arg_pointer_rtx will become a frame pointer later
one too. The only issue is that there might not be correct dependencies with
respect of arg_pointer_rtx.
Kenny,
Do you agree?
