WebIn this paper, we present a new method for supporting abstraction refinement in path-sensitive dataflow analysis. We show how an adjustable merge criterion can be used as an interface to control the degree of abstraction. In particular, we partition the merge criterion with two sets of predicates – one related to the dataflow facts being […] WebData Flow Analysis Schema • Build a flow graph (nodes = basic blocks, edges = control flow) • Set up a set of equations between in[b] and out[b] for all basic blocks b –Effect of …
