| 摘要: |
| 为解决冗余代码缺陷检测复杂度较高且检测精度较低的问题,设计并实现了基于控制结构的冗余代码检测模型．通过对TOKEN序列建立复合语句结构信息表,精简了程序的控制依赖关系,并在此基础上对幂等操作、死代码以及冗余赋值3种冗余代码进行检测,有效降低了缺陷检测复杂度．通过分析Linux开源代码表明,本模型可以快速的检测大规模程序,并且具有较低的误报率和漏报率．因此本模型可以帮助程序员发现进而修正软件缺陷,维护软件可靠性． |

| Abstract: |
| To deal with the problems such as high complexity and low accuracy of redundancy detection, a model of redundancy detection based on control structure analysis is proposed and implemented. This paper predigests the complexity of control structure by establishing a compound node table for tokens, which reduces the complexity of redundancy detection, and then detects the idempotent operations, dead code and redundant assignment. Experimental results of the open source code of Linux show that this model can find redundant code accurately and also has a low time-complexity. With this model, it is very convenient for developers to detect and correct these kinds of defects, and thereby to further guarantee the software quality. |
