Static analysis of concurrent software for deriving synchronization constraints

A static analysis method is introduced for detecting synchronization errors. This method is to derive constraints on the feasible synchronization sequences of a concurrent program (or program module) P according to P´s syntactic and semantic information. These constraints, called feasibility constraints for P, can be compared with constraints in the specification of P to detect specification-dependent errors and can be analyzed to detect specification-independent errors such as deadlock. Feasibility constraints for P can be used to improve the accuracy of existing methods for deriving approximations of the set of feasible SYN-sequences of P
