Abstract
Program fusion is the process whereby separate pieces of code are fused into a single piece, typically transforming a multi-pass algorithm into a single pass.
Recent work has made it clear that the process is especially successful if the loops or recursions are expressed using catamorphisms (e.g.foldr) and
constructor-abstraction (e.g. build). In this paper we show how to transform recursive programs into this form automatically, thus enabling the fusion transformation
to be applied more easily than before.
The algorithm in this paper has been implemented in a couple of systems including HSX (WarmFusionInStratego).
