ABSTRACT:
According to a generated instruction, the present invention provides an information processing method for performing processing by using a CPU that comprises at least one register. The method comprises the steps of: judging whether or not each of the registers is valid in the instruction; identifying a register whose value is changed by an interrupt processing generated in the instruction; and calculating a number of registers to be evacuated in the interrupt processing based on valid judgment information of the register and identification information of the register whose value is changed by the interrupt processing, and determining whether or not the interrupt processing is permitted based on a calculation result thereof.
