In this paper we propose a precise goal-independent abstract interpretation of Prolog programs. We deal with the control rules of Prolog and the cut operator. Moreover, we get a simple denotation for negation as finite failure. The abstract analysis is proposed both for computed answers analysis and for call patterns analysis. In both cases the abstract semantics is finitely computable.

Abstract
In this paper we propose a precise goal-independent abstract interpretation of Prolog programs. We deal with the control rules of Prolog and the cut operator. Moreover, we get a simple denotation for negation as finite failure. The abstract analysis is proposed both for computed answers analysis and for call patterns analysis. In both cases the abstract semantics is finitely computable.
