An Object Oriented Model for Semantics Directed Compiler Generation

Luiz Carlos Castro GuedesEdward Hermann HaeuslerJosé Lucas Range

This paper describes a semantic model suitable for a compiler generation system that takes as input the denotational description of the source language. The model proposed here maps the denotational definition of a programming language to an Object Oriented program in an adequate language. The core of the model is the mapping from syntactic and semantic domains into classes, and from semantic functions into methods of those classes. Semantic equations are mapped to the implementation of some of those methods. Its correctness has been proved and a system prototype implemented. Performance tests have shown our system outperforms similar systems and that its produced compilers are just one order of magnitude slower than hand written ones. The great efficiency of the model is a promising step towards the automatically generation of production quality compilers. Thus, a natural and elegant model to translate programming language descriptions into realistic compilers with its correctness guaranteed has been obtained.
