Declarative Specialization for Object-Oriented-Program Specialization

Abstract

The use of partial evaluation for specializing programs written in im- perative languages such as C and Java is hampered by the di-culty of controlling the specialization process. We have developed a simple, declar- ative language for controlling the specialization of Java programs, and in- terfaced this language with the JSpec partial evaluator for Java. This lan- guage, named Pesto, allows declarative specialization of programs written in an object-oriented style of programming. The Pesto compiler auto- matically generates the context information needed for specializing Java programs, and automatically generates guards that enable the specialized code in the right context
