Static Single Assignment (SSA) has become the intermedi-
ate program representation of choice in most modern com-
pilers because it enables efficient data flow analysis of scalars
and thus leads to better scalar optimizations. Unfortunately
not much progress has been achieved in applying the same
techniques to array data flow analysis, a very important and
potentially powerful technology. In this paper we propose
to improve the applicability of previous efforts in array SSA
through the use of a symbolic memory access descriptor
that can aggregate the accesses to the elements of an ar-
