A Register Allocation Technique Using Guarded PDG

Abstract

Register allocation for instruction-level parallel processors involves problems that are not considered in register allocat,i on for scalar processors. First, when the same register is allocated to different variables, anti-dependence is gtmerated, which decreases instruction-level parallelism. Second, spill code should be inserted at a suitable position in… (More)
