System and method for generating error traces for concurrency bugs

摘要

A system and method for program verification includes generating a product transaction graph for a concurrent program, which captures warnings for potential errors. The warnings are filtered to remove bogus warnings, by using constraints from synchronisation primitives and invariants that are derived by performing one or more dataflow analysis methods for concurrent programs. The dataflow analysis methods are applied in order of overhead expense. Concrete execution traces are generated for remaining warnings using model checking.
