Tukra: An Abstract Program Slicing Tool

We introduce Tukra, a tool that allows the practical evaluation of abstract program slicing algorithms. The tool exploits the notions of statement relevancy, semantic data dependences and conditional dependences. The combination of these three notions allows Tukra to refine traditional syntax-based program dependence graphs, generating more accurate slices. We provide the architecture of the tool, some snapshots describing how it works, and some preliminary experimental results giving evidence of the accuracy improvements it supports.
