Dataflow analysis
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 […] WebControl Flow Analysis and Data Flow Analysis work well if we can statically observe every dependency from the source code. That is not always the case. Pointers obscure data dependencies. Pointers can alias other variables so that a read/write from a dereferenced pointer really is a dependency into another variable (while at the same time being ...
