| Research Abstract |
In order to decrease the number of memory accesses, we have implemented a technique aggregating array references in continuous for improving cache-efficiency, and a technique applying the scalar replacement, which replaces array references with register references over some iterations of a loop, to an entire program. Also, in order to improve the efficiency of these techniques, we have developed the demand-driven partial redundancy elimination based on the global value numbering, and then have developed the demand-driven partial dead code elimination applying the demand-driven property to the partial dead code elimination.
