Automatic translation of Fortran to JVM bytecode

ABSTRACT

This paper reports on the design of a FORTRAN-to-Java translator whose target language is the instruction set of the Java Virtual Machine. The goal of the translator is to generate Java implementations of legacy FORTRAN numerical codes in a consistent and reliable fashion. The benefits of directly generating bytecode are twofold. First, it provides a much more straightforward and efficient mechanism for translating FORTRAN GOTO statements. Second, it provides a framework for pursuing various compiler optimizations, which could be beneficial not only to our project, but to the Java community as a whole.
