Abstract: PROBLEM TO BE SOLVED: To properly select instructions to be optimized as a priority.
SOLUTION: A compiler program that optimizes a target program to be compiled includes an instruction detecting unit for detecting an instruction of a predetermined type as an optimization-target instruction to be optimized in precedence over other instructions in the target program; an instruction set selecting unit for selecting a set of optimization-target instructions, the set being a set of instructions the order of execution of which is determined with respect to the detected optimization-target instruction and being executed before the optimization-target instruction; and an optimizing unit for optimizing the target program so that the optimization-target instruction set is executed more efficiently than the instructions other than the optimization-target instruction set.
