Abstract.

Formulog extends Datalog with mechanisms for constructing logical terms and reasoning about them with satisfiability modulo theories (SMT) solving; a first-order functional language aids inspecting and manipulating complex terms. This combination of features makes it possible to write complex SMT-based program analyses in a way close to their formal specification, while being satisfactorily performant thanks to powerful Datalog optimizations and efficient evaluation techniques.
