  • Publication number: 20180181485
    Abstract: A source code equivalence verification device performs symbolic execution on both an original source code and a modified version of the original source code; generates, using the results of the symbolic execution, equivalence verification expressions for verifying equivalence between the original source code and the modified source code; and verifies the equivalence verification expressions. A correction candidate generation unit generates a correction candidate, on the basis of which the modified source code is to be corrected so as to be equivalent to the original source code, if the results of the verification of the equivalence verification expressions indicate that the modified source code is not equivalent to the original source code; and a verification result generation unit generates a verification result report using the results of the verification and the correction candidate generated by the correction candidate generation unit.

  • Patent number: 9779009
    Abstract: When verifying rapidly the equivalence between source codes with respect to refactoring, the present invention performs two types of verification: verification based on structural comparison using structure graphs obtained by analyzing the source codes, and verification based on symbolic execution. If the structural comparison using the structure graphs can verify that the structures are identical with each other, then symbolic execution is not performed. Further, before the verification based on the structural comparison, the structure graphs of the source codes before and after refactoring are normalized on the basis of normalization information, which is defined for each refactoring pattern, and thereby adjusted so that the resulting structures are identical with each other when the refactoring is valid.
