  year: "2001"
  doi: "http://link.springer.de/link/service/series/0558/bibs/2053/20530173.htm"
  abstract: "Object-oriented programming facilitates the development of generic software, but at a significant cost in terms of performance. We apply partial evaluation to object-oriented programs, to automatically map generic software into specific implementations. In this paper we give a concise, formal description of a simple partial evaluator for a minimal object-oriented language, and give directions for extending this partial evaluator to handle realistic programs. Based on workdo ne in the Compose Group at IRISA/INRIA, Rennes, France; supported in part by Bull."

  abstract: "Design patterns offer many advantages for software development, but can introduce inefficiency into the final program. Program specialization can eliminate such overheads, but is most effective when targeted by the user to specific bottlenecks. Consequently, we propose that these concepts are complementary. Program specialization can optimize programs written using design patterns, and design patterns provide information about the program structure that can guide specialization. Concretely, we propose specialization patterns, which describe how to apply program specialization to optimize uses of design patterns. We analyze the specialization opportunities provided by specific uses of design patterns. Based on the analysis of each design pattern, we define the associated specialization pattern. These specialization opportunities can be declared using the specialization classes framework, developed previously. In our experiments, such specialization significantly improves performance"

  abstract: "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 compilation technology fails to compensate for the use of object-oriented abstractions to implement generic programs, and that program specialization can be used to eliminate these overheads. We present an automatic program specializer for Java, and demonstrate experimentally that significant speedups in program execution time can be obtained through automatic specialization. Although automatic program specialization could be seen as overlapping with existing optimizing compiler technology, we show that specialization and compiler optimization are in fact complementary."
