Compiler Optimization-Space Exploration

By Spyridon Triantafyllis, Manish Vachharajani and David I. August

Abstract

To meet the performance demands of modern architectures, compilers incorporate an everincreasing number of aggressive code transformations. Since most of these transformations are not universally beneficial, compilers traditionally control their application through predictive heuristics, which attempt to judge an optimization's effect on final code quality a priori. However, complex target architectures and unpredictable optimization interactions severely limit the accuracy of these judgments, leading to performance degradation because of poor optimization decisions
