It is very efficient. The logical\/proof theoretic approach uses SMT solvers\/theorem provers and computation of property transformers on-the-fly. It is very expressive. We propose to unify both approaches, so that they can be combined to reach the sweet spot best adapted to a specific application domain in the precision\/cost spectrum. We first give a new formalization of the proof theoretic approach in the abstract interpretation framework, introducing a semantics based on multiple interpretations to deal with the soundness of such approaches. Then we describe how to combine them with any other abstract interpretation-based analysis using an iterated reduction to combine abstractions. The key observation is that the Nelson-Oppen procedure which decides satisfiability in a combination of logical theories by exchanging equalities and disequalities computes a reduced product (after the state is enhanced with some new \u201cobservations\u201d corresponding to alien terms). By abandoning restrictions ensuring completeness (such as disjointness, convexity, stably-infiniteness, or shininess, etc) we can even broaden the application scope of logical abstractions for static analysis (which is incomplete anyway).
