代码克隆是多个代码片段，当提供相同的输入时，它们会产生相似的结果。先前的研究表明，克隆可能是有害的，因为它们会提高维护成本，增加由于克隆代码的不一致更改而导致的错误数量，并且可能会由于代码库大小的增加而降低程序员的理解性。为了帮助检测代码克隆，我们提出了一种称为 Concolic 代码克隆发现 (CCCD) 的新工具。 CCCD 是第一个已知的克隆检测工具，它使用 concolic 分析作为其主要组成部分，并且是能够可靠检测最复杂的克隆（4 型克隆）的仅有的三种已知技术之一。
Code clones are multiple code fragments that produce similar results when provided the same input. Prior research has shown that clones can be harmful since they elevate maintenance costs, increase the number of bugs caused by inconsistent changes to cloned code and may decrease programmer compre-hensibility due to the increased size of the code base. To assist in the detection of code clones, we propose a new tool known as Concolic Code Clone Discovery (CCCD). CCCD is the first known clone detection tool that uses concolic analysis as its primary component and is one of only three known techniques which are able to reliably detect the most complicated kind of clones, type-4 clones.
