Abstract

Traditional techniques for array analysis do not provide dataflow information, and thus traditional dataflow-based scalar optimizations have not been applied to array elements. A number of techniques have recently been developed for producing information about array dataflow, raising the possibility that dataflow-based optimizations could be applied to array elements. In this paper, we show that the valuebased dependence relations produced by the Omega Test can be used as a basis for generalizations of several scalar optimizations.
