is this something which will actually be executed a lot? In this
case the code for lea a5@,a5 will work better, as it won't synchronize
the pipeline. (and it will execute in the first stage of the
pipeline, so that the next instruction won't stall if it accesses
a3, on 68040/60; and not using a0,a1 (caller-saved) or a7 (stack
pointer), it won't prevent superscalar dispatch on the 68060).
