Talk on
Goal-Directed Abstract Interpretation and Event-Driven FrameworksSAS 20232023-10-22
Argues for goal-directed backward analysis that models only callbacks relevant to a single error, implements abstract message histories to represent realizable…
Talk
Lifting On-Demand Analysis to Higher-Order LanguagesSAS 20232023-10-22
Claims an on-demand algorithm that bootstraps call graph construction by interleaving two on-demand data‑flow queries, formalizes the method as an…
