Abstract:
A method of adjusting a control timing accompanying a program correction of a machine language program executed by an information processor includes preparing a first machine language program obtained by compiling a first source program and generating a second intermediate language program from a second source program, the second source program being corrected from the first source program. Then, the method computes a first number of clock cycles, that is a number of clock cycles to execute a first machine language program obtained by compiling the first source program and computes a second number of clock cycles, that is a number of clock cycles to execute a second machine language program obtained by compiling the second source program, using the second intermediate language program, the second intermediate language program including an instruction that is uniquely correlated with a machine language instruction of the second machine language program.
