Abstract

This document describes the intermediate program representation DCode. The representation is an ASCII format which specifies instructions for an abstract stack machine. Interpretive code generators may process this file to produce object code for various target machines. The semantics of each instruction in the code is explained, and the various directives detailed. This document is intended to serve as a guide for those wishing to create new code generator backends for the existing compilers, and for those wishing to create frontends for a new language for the existing code generators. The first part of the report is a concise reference manual for the language, while the second part is a detailed description of the way in which the language is used in typical cases. The second part describes the way in which the form is used in typical cases, and contains a number of examples.
