Abstract
Prefetching irregular memory references into a software controlled cache is provided. A compiler analyzes source code to identify at least one of a plurality of loops that contain an irregular memory reference. The compiler determines if the irregular memory reference within the at least one loop is a candidate for optimization. Responsive to an indication that the irregular memory reference may be optimized, the compiler determines if the irregular memory reference is valid for prefetching. Responsive to an indication that the irregular memory reference is valid for prefetching, a store statement for an address of the irregular memory reference is inserted into the at least one loop. A runtime library call is inserted into a prefetch runtime library for the irregular memory reference. Data associated with the irregular memory reference is prefetched into the software controlled cache when the runtime library call is invoked.
