### Abstract

This paper presents a framework for comparing two strictness analysis techniques: Abstract interpretation and non--standard type inference. The comparison is based on the representation of a lattice by its ideals. A formal system for deducing inclusions between ideals of a lattice is presented and proved sound and complete. Viewing the ideals as strictness properties we use the formal system to define a program logic for deducing strictness properties of expressions in a typed lambda calculus. This strictness logic is shown to be sound and complete with respect to the abstract interpretation, which establishes the main result that strictness analysis by type--inference and by abstract interpretation are equally powerful techniques. 1 Introduction Abstract interpretation is a well--established technique for static analysis of programs. Its virtue is its strong connection with denotational semantics which provides a means of proving the analysis correct. Its vice is that the process of...

In this paper we shall take an abstract interpretation to be a denotational semantics (see e.g., =-=[13]-=-) for which the denotation of any program is effectively computable. One way of achieving effectiveness is by requiring the domains used in the interpretation to be finite. This on the other hand intr... |
