Also, what about the case of expanding code size to take advantage of a
deep pipeline? Isn't this working at cross purposes with attempting to
maintain locality of reference? If you insert instructions into the
instruction stream to keep the pipe full, are you shooting yourself in
the foot as far as the cache hit rate is concerned?


Has anyone run into this issue before?
