1. A method for providing a transparent profile-feedback optimization environment for developing an optimized version of an original compiled application program, the compiled software application program including a plurality of original executable images, the method comprising the steps of: instrumenting the original executable images of the compiled application program to produce instrumented images, each instrumented image containing references only to other instrumented images; transparently executing the instrumented images to generate profile data, such that when the instrumented images execute, they appear to execute just as the original executable image executes; optimizing the original executable images of the compiled software application, in accordance with the profile data generated by executing the instrumented images, to generate optimized images of the original executable images, each optimized image containing references only to other optimized images.
