Computing liveness sets for ssa-form programs
Did you know?
WebThe SSA form is a popular compiler intermediate language allowing for simple and fast optimizations. Boissinot et al. [7] designed a fast liveness analysis by combining the specific properties of SSA with graph-theoretic ideas such as depth-first search and dominance. WebThereby, we heavily make use of SSA-form properties, which allow us to completely circumvent data-flow equation solving. We evaluate the competitiveness of our approach …
WebJun 6, 2024 · Like T, C is defined as the reflexive and transitive closure of C ↑, where C t ↑ (cf. Definition 2) associates to node t the set of cross edge targets not tree reachable (i.e. reachable in the spanning tree) from t but whose source is tree reachable from t. In Fig. 2 a, only C 8 ↑ = { 7 } is non-empty. WebLiveness analysis is a standard compiler analysis, enabling several optimizations such as deadcode elimination.
