ABSTRACT:
The present invention is a system and process for optimizing programs, having memory references, at the object code level. The process includes the computer-implemented steps of instrumenting each of the memory references to create an instrumented program, executing the instrumented program to capture effective address trace data for each of the memory references, analyzing the access patterns of the effective address trace data and, in response, reordering the memory references to create an optimized program.
