  • Patent number: 10379886
    Abstract: A non-transitory computer-readable medium stores computer-executable instructions that, when executed by a computer, cause the computer to perform operations including generating a changed optimization file by changing an original optimization file, the original optimization file being an optimization file created at a point in time at which an intermediate language file for an application is loaded; storing the changed optimization file; creating and storing verification information for verifying whether the intermediate language file is changed; determining whether the intermediate language file is changed based on the stored verification information in response to reloading of the intermediate language file; and creating a new optimization file by deleting the changed optimization file or recovering the original optimization file based on the changed optimization file and reusing the original optimization file, based on whether the intermediate language file is changed.
