* Results from de.uni_freiburg.informatik.ultimate.plugins.generator.referee:
- AnnotationCheckResult: Annotation is a valid proof of correctness.
Annotation is a valid proof of correctness.
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 loop head at line 16 to check that procedure precondition always holds at line 16.
Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to check that a call to reach_error is unreachable at line 8.
