Abstract: Parallelizing compiler has made great progress in recent years. In order to achieve the maximum parallelism, run-time techniques are used in the parallelizing compiler during last few years. Most run-time techniques are based upon forward data flow analysis. In this paper, we presented a new run-time data flow analysis BPD test which can use backward information to exploit more dynamic parallelism under complex control flow. In the end of this paper we take the program fpppp. f of Spec95fp benchmark as an example, to show the effectiveness of BPD test. ;;;
