Automatic program specialization for Java
The object-oriented style of programming facilitates program adaptation and enhances program genericness, but at the expense of efficiency. We demonstrate experimentally that state-of-the-art Java compilers fail to compensate for the use of object-oriented abstractions in the implementation of generic programs, and that program specialization can eliminate a significant portion of these overheads. We present an automatic program specializer for Java, illustrate its use through detailed case studies, and demonstrate experimentally that it can significantly reduce program execution time. Although automatic program specialization could be seen as being subsumed by existing optimizing compiler technology, we show that specialization and compiler optimization are in fact complementary.
