Fast and Safe Concrete Code Execution for Reinforcing Static Analysis and Verification
Abstract
The problem of improving precision of static analysis and verification techniques for C is hard due to simplification assumptions these techniques make about the code model. We present a novel approach to improving precision by executing the code model in a controlled environment that captures program errors and contract violations in a memory and time efficient way. We implemented this approach as an executor module Tassadar as a part of bounded model checker Borealis. We tested Tassadar on two test sets, showing that its impact on performance of Borealis is minimal.The article is published in the authors’ wording.
