1. A method comprising: generating a first executable program optimized for an executable system based on compiling a program relative to an initial set of independent optimization metrics; determining first performance metrics based on the executable system executing the first executable program; adjusting the initial set of independent optimization metrics based on the first performance metrics to generate a second set of independent optimization metrics; and generating a second executable program, based on compiling the program relative to the second set of independent optimization metrics, for improved execution of the program in the executable system.
