摘要
A method for data flow analysis, comprising: obtaining, by a processing circuitry, an execution trace of a software program; dividing, by the processing circuitry, the execution trace into a plurality of sections; generating a plurality of definition-and-usage chains, at least some of the definition-and-usage chains being generated by different processors, at least some of the definition-and-usage chains being generated based on different sections of the execution trace, at least two of the definition-and-usage chains being generated in parallel with one another; combining, by the processing circuitry, the plurality of definition-and-usage chains to produce a data flow graph, the definition-and-usage chains being combined based on information provided by at least one of the processors that are used to generate the definition-and-usage chains, the information indicating one or more unresolved memory locations that are accessed by respective operations corresponding to one or more incomplete usage nodes in the definition-and-usage chains.
