Multi-criticality real-time systems require protected-mode operating systems with bounded interrupt latencies and guaranteed isolation between components. A tight WCET analysis of such systems requires trustworthy information about loop bounds and infeasible paths. We propose sequoll, a framework for employing model checking of binary code to determine loop counts and infeasible paths, as well as validating manual infeasible path annotations which are often error-prone. We show that sequoll automatically determines many of the loop counts in the Malardalen WCET benchmarks. We also show that sequoll computes loop bounds and validates several infeasible path annotations used to reduce the computed WCET bound of seL4, a high-assurance protected microkernel for multi-criticality systems.
