摘      要：We present the (RD2)-D-2 redundancy detector. (RD2)-D-2 identifies redundant code fragments in large software systems written in Lisp. For each pair of code fragments, (RD2)-D-2 uses a combination of techniques ranging from syntax-based analysis to semantics-based analysis, that detects positive and negative evidences regarding the redundancy of the analyzed code fragments. These evidences are combined according to a well-defined model and sufficiently redundant fragments are reported to the user. (RD2)-D-2 explores several techniques and heuristics to operate within reasonable time and space bounds and is designed to be extensible.
