Annotation is valid for all loop-free paths from loop head at line 23 to check that procedure precondition always holds at line 23. Annotation is valid for all loop-free paths from loop head at line 23 to check that procedure precondition always holds at line 26. Annotation is valid for all loop-free paths from entry of procedure foo to exit of procedure foo. Annotation is valid for all loop-free paths from loop head at line 23 to exit of procedure main. Annotation is valid for all loop-free paths from loop head at line 23 to check that procedure precondition always holds at line 25. Annotation is valid for all loop-free paths from entry of procedure main to loop head at line 23. Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to exit of procedure __VERIFIER_assert. Annotation is valid for all loop-free paths from entry of procedure ULTIMATE.start to check that procedure precondition always holds at line -1. Annotation is valid for all loop-free paths from loop head at line 23 to loop head at line 23. * Results from de.uni_freiburg.informatik.ultimate.core: - StatisticsResult: Toolchain Benchmarks Benchmark results are: * Witness Parser took 0.17ms.
