.In .hw de-vised .TL A fast backend for SPARC processors .AU Philip Homburg Raymond Michiels .AI Dept. of Mathematics and Computer Science Vrije Universiteit Amsterdam, The Netherlands .AB The language EM is an intermediate language for use in compiler construction. In this paper we describe the construction of a so-called fast backend which translates EM code to assembler for SPARC processors. .br Our construction deviates strongly from the usual procedure. We have devised and implemented a virtual stack with which it is possible to generate very acceptable code without much loss in compile time. .AE .PP .bp
