PROGRAM DEVELOPMENT APPARATUS, METHOD FOR DEVELOPING A PROGRAM, AND A COMPUTER PROGRAM PRODUCT FOR EXECUTING AN APPLICATION FOR A PROGRAM DEVELOPMENT APPARATUS

A program development apparatus includes a storage device configured to store an operation definition defining a program description in a source program subjected to be optimized and a complex intrinsic function including an inline clause describing statements after the optimization. An analyzer is configured to perform a syntax analysis of the complex intrinsic function by reading the complex intrinsic function out of the storage device, so as to detect the operation definition and the inline clause. A code generator is configured to generate an object code from the source program by optimizing a program description corresponding to the operation definition in the source program into the statements in the inline clause.
