Abstract:Complex dependence analysis typically provides an underpinning approximation of true program dependence. We investigate the effectiveness of using lexical information to approximate such dependence, introducing two new deletion operators to Observation-Based Slicing (ORBS). ORBS provides direct observation of program dependence, computing a slice using iterative, speculative deletion of program parts. Deletions become permanent if they do not affect the slicing criterion. The original ORBS uses a bounded delet… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
