- 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 entry of procedure __VERIFIER_assert to check that a call to reach_error is unreachable at line 17.
Annotation is valid for all loop-free paths from entry of procedure main to check that procedure precondition always holds at line 24.
