Fang’s and Jim’s paper “Weighted System Dependence Graph” was accepted for publication at ICST 2012! This paper provides a new program-analysis model of software code for a program. The model augments static (i.e., compile-time) whole-program dependencies among instructions with dynamic (i.e., run-time) information describing how the instructions were executed. Existing static models provide information about which instructions may affect others, and existing dynamic models provide information about which instructions did affect others. In contrast, our new hybrid model allows for the assessment of the degree to which instructions affect each other. We envision applications of the model for supporting numerous software-maintenance tasks.
