- AnnotationCheckResult: Annotation is not a valid proof of correctness.
Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from loop head at line 41 to loop head at line 41. One counterexample starts in A=-4294967296, B=-4294967295, b=0, q=0, r=0 and ends in A=-4294967296, b=0, B=-4294967295, q=1, r=0.
Insufficient resources for checking whether annotation is valid for all loop-free paths from loop head at line 41 to check that procedure precondition always holds at line 42.
Annotation is valid for all loop-free paths from entry of procedure assume_abort_if_not to exit of procedure assume_abort_if_not.
Annotation is valid for all loop-free paths from loop head at line 37 to loop head at line 37.
Annotation is valid for all loop-free paths from loop head at line 41 to check that procedure precondition always holds at line 41.
Annotation is valid for all loop-free paths from entry of procedure main to loop head at line 37.
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 20.
