7. The program development apparatus of claim 1 , wherein the code generator comprises: an intermediate code generator configured to convert the source program, the statements in the inline clause, and the operation definition into an intermediate code; an intermediate code optimizer configured to execute optimization to an intermediate code of the source program by utilizing an intermediate code of the statements in the inline clause and the operation definition; and an object code generator configured to generate the object code from an optimized intermediate code.
