Combinations of Abstract Domains for Logic Programming

Abstract interpretation [7] is a systematic methodology to design static program analysis which has been studied extensively in the logic programming community, because of the potential for optimizations in logic programming compilers and the sophistication of the analyses which require conceptual support. With the emergence of efficient generic abstract interpretation algorithms for logic programming, the main burden in building an analysis is the abstract domain which gives a safe approximation of the concrete domain of computation. However, accurate abstract domains for logic programming are often complex because of the variety of analyses to perform, their interdependence, and the need to maintain structural information. the purpose of this paper is to propose conceptual and software support for the design of abstract domains.
