A method of detecting deadlock in a multithreading program is provided. An invocation graph is constructed having a single root and a plurality of nodes corresponding to one or more functions written in code of the multithreading program. A resource graph is computed in accordance with one or more resource sets in effect at each node of the invocation graph. It is determined whether cycles exist between two or more nodes of the resource graph. A cycle is an indication of deadlock in the multithreading program.
