To date, most clone detection techniques have concentrated on various forms of source code analysis, often by analyzing token streams. In this paper, we introduce a complementary technique of analyzing generated assembler for clones. This approach is appealing as it is mostly impervious to trivial changes in the source, with compilation serving as a kind of normalization technique. We have built detectors to analyze both Java VM code as well as GCC Linux assembler for C and C++. In the paper, we describe our approach and show how it can serve as a valuable complementary semantic approach to syntactic source code based detection.
