code clone is a code fragment identical or similar
to another code fragment in source code. Some of code clones are considered as a factor of bug replications and make it more difficult to maintain software. Various code clone detection tools have been proposed so far. However, in most algorithms adopted by existing clone detection tools, if program statements are reordered, they are not detected as code clones. In this research, we examined how clone detection results change by rearranging the order of program statements. We performed preprocessing to rearranging the order of program statements using program dependency graph (PDG). We compared clone detection results with and without preprocessing. As a result, by rearranging the order of program statements, the number of detected code clones is almost the same in most projects. We classified newly detected or disappeared clones manually. From our experimental results, we show that there is no newly detected clone whose statements are reordered and that there are four disappeared clones whose statements are reordered. We think three out of the four clones occurred by copy-and-paste operations. Therefore, we conclude that rearranging the order of program statements is not effective to detect reordered code clones. |
