摘要: A computer-implemented process for deductive reaching definition analysis receives a control flow graph to form set of received blocks and edges, performs traditional definitions produce bit-vectors OUT(b), GEN(b) KILL(b) each block in the impossibility indicators that are impossible on specific edges. The further deduction operations using combination deduce additional cannot reach certain create resulting reachability information provides as result requestor. related system program product is also provided.
