Method and device for identifying semantic difference between source code versions

The invention relates to a method and a device for identifying semantic difference between source code versions. In one embodiment of the invention, a method for identifying the semantic difference between the source code versions is provided, comprising: respectively obtaining first debugging information of a first source code version and second debugging information of a second source code version; comparing the first debugging information with the second debugging information, and determining whether a second function matched with a first function in the first source code version exists in the second source code version; and identifying the semantic difference based on the determined result. In one embodiment of the invention, a device for identifying the semantic difference between the source code versions is provided. By adopting the method and the device provided by the invention, the semantic difference between the source code versions can be identified quickly and accurately.
