PROGRAM REWRITER AND COMPUTER READABLE RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a program rewriter for preventing the increase of a code size even while parallel executability is improved. SOLUTION: When scheduling for performing parallel execution is performed by a scheduling device 14, this program rewriter 15 extracts instruction sets composed of instructions for defining values in respective registers and the instructions for referring to the values defined in the registers and detects existing sections for respective definition values for the respective instruction sets. The plural instructions included in the two instruction sets whose existing sections are not overlapped with each other for defining the values in mutually different resources and referring to the values defined in the mutually different resources are rewritten to the instructions for defining the values in the same resource and the instructions for referring to the values defined in the same resource.
