So essentially, we divide the program into nodes or …
WebFlow Sets. In dataflow analysis, we seek to associate some data with each node in the control-flow graph. In Soot, we represent this data as flow sets. Typically, a flow set represents a set of facts. For reaching definitions, the flow sets are the sets of pairs (variable, program point). Soot defines the FlowSet interface to be the canonical ... WebData flow analysis is a static analysis technique for calculating facts of interest at each program point based upon the control flow graph representation of the program. Gary …
