Any such technique must also take into account the possibility that quantities
allocated to registers may also be aliased (i.e. register addresses must also
be monitored and forwarded.)


A technique that solves this problem has been developed and a paper describing
the technique and its use has been submitted for publication. A copy of the
paper is available by sending me e-mail at heggy@cs.pitt.edu.


The paper is:
B. Heggy and M.L. Soffa, "Architectural Support for Register
Allocation in the Presence of Aliasing", Submitted for
publication.
