Abstract

We describe and evaluate the linear scan register allocator proposed recently by Poletto and Sarkar, and extensively report on its implementation and behaviour in the context of a native code compiler for the concurrent functional programming language Erlang. We also investigate how different options of the basic algorithm and of the compilation process as a whole affect compilation time and quality of the produced code.
