Whale: An Interpolation-Based Algorithm for Inter-procedural Verification [chapter]

Aws Albarghouthi, Arie Gurfinkel, Marsha Chechik
2012 Lecture Notes in Computer Science  
In this paper, we propose an interpolation-based software verification algorithm for checking safety properties of (possibly recursive) sequential programs.  ...  Our algorithm, called Whale, produces inter-procedural proofs of safety by exploiting interpolation for guessing function summaries by generalizing under-approximations (i.e., finite traces) of functions  ...  Compared to Whale, this makes them better suited for bug finding. Conclusion and Future Work In this paper, we presented Whale, an interpolation-based algorithm for interprocedural verification.  ...
