This paper describes an intermediate language to be generated by a syntax analyzer and processed by a code generator. An (essentially) optional code optimization phase may be used before code generation. The language is designed to exclude source and target dependencies (these are specified in a set of auxiliary tables) and has been used to implement a general purpose code optimization module. This module has been incorporated into compilers for several source languages and has resulted in production-quality target code. The paper focuses on the features of the language and reviews the optimizations for which it has been designed. A major benefit of this approach has been to isolate many of the characteristics which lead to code optimization opportunities. Of particular note are numerous facts which can be gathered in a target-independent manner, even though their utilization will depend on the details of the target machine.
