This paper presents a systematic approach to the problem of generating good code with a compiler that is easy to construct. A compiler structure is proposed which relies on interprocedural data flow analysis, global optimization, and an intermediate language schema to simplify the task of writing the code generating portions of a compiler without sacrificing code quality. This structure is contrasted with a more conventional structure to explore the reasons why the new structure solves several problems inherent in the conventional structure. Further advantages which accrue from the new structure are also presented.
