Abstract

The low level virtual machine(LLVM) is a widely used compiler framework. Its intermediate representation(IR) contains abundant program analysis information, and many related work based on program analysis takes a basis of IR. Data dependence plays an important role in fault detection, fault location, and program debugging. IR-based data-dependence computing often adopts serial iterative approaches, such approaches usually suffer scalability issues when dealing with larger-scale IR contents. To address above issues, this paper carried out the parallelism mining of instructions reading and writing in data dependence calculation. Combined with the parallel computing advantages of graphics processing unit, it proposed a parallel computing method DRPC based on LLVM IR. This method accepted IR as inputs, and achieved efficient program data dependence computation through a CPU-GPU cooperation way. The experimental results show that DRPC's highest speedup is 3.48x and 4.9x respectively in the direct and transitive data dependence computation with benchmark SPEC.
