Algorithms for Infeasible Path Calculation

Jan Gustaffson, Andreas Ermedahl & BjöRn Lisper
Static Worst-Case Execution Time (WCET) analysis is a technique to derive upper bounds for the execution times of programs. Such bounds are crucial when designing and verifying real-time systems. One key component in static WCET analysis is to derive flow information, such as loop bounds and infeasible paths for the analysed program. Such flow information can be provided as either as annotations by the user, can be automatically calculated by a flow analysis, or by...
