Abstract

Mechanisms are provided for optimizing regular memory references in computer code. These mechanisms may parse the computer code to identify memory references in the computer code. These mechanisms may further classify the memory references in the computer code as either regular memory references or irregular memory references. Moreover, the mechanisms may transform the computer code, by a compiler, to generate transformed computer code in which regular memory references access a storage of a software cache of a data processing system through a high locality cache mechanism of the software cache.
