Abstract:

We show that the classical approach to the soundness of dataflow analysis is with respect to a syntactic path abstraction that may be problematic with respect to a semantics trace-based specification. The fix is a rigorous abstract interpretation based approach to formally construct dataflow analysis algorithms by calculational design.
