Abstract

Program analysis and verification techniques have made great strides, yet, as every researcher in the field will admit it is easy to find a program and property for which a given technique is not cost-effective. Investigating the conventional wisdom that programs are mostly correct, we have observed that even failed program analyses usually produce a wealth of information about the parts of the program that operate correctly. Leveraging this information can help focus subsequent analysis and verification activities to make them more cost-effective.
