More and more devices contain computers with limited amounts of memory. As a result, code compaction techniques are gaining popularity, especially when they also improve performance and power consumption, or at least not degrade it. This paper quantifies the side-effects of code abstraction on performance using extensive measurements and simulations on the SPECint2000 benchmark suite and some additional C++ programs. We show how to use profile information in order to obtain almost all the code size reduction benefits of code abstraction, yet experience almost none of its disadvantages.
