Phoenix-based clone detection using suffix trees

A code clone represents a sequence of statements that are duplicated in multiple locations of a program. Clones often arise in source code as a result of multiple cut/paste operations on the source, or due to the emergence of crosscutting concerns. Programs containing code clones can manifest problems during the maintenance phase. When a fault is found or an update is needed on the original copy of a code section, all similar clones must also be found so that they can be fixed or updated accordingly. The ability to detect clones becomes a necessity when performing maintenance tasks. However, if done manually, clone detection can be a slow and tedious activity that is also error prone. A tool that can automatically detect clones offers a significant advantage during software evolution. With such an automated detection tool, clones can be found and updated in less time. Moreover, restructuring or refactoring of these clones can yield better performance and modularity in the program. Thi...
