Abstract

Since the approach of building specialized systems from existing general-purpose components is becoming more common, there is a growing need for global optimization tools that accomplish the functional requirements of these systems. The first approach for developers is to apply the current optimization techniques individually on each component. Nevertheless, these optimizations do not always improve the code enough and manual tuning must be done afterward.This paper presents a new approach for global optimization based on building a global view of the system, a global control flowgraph. The paper summarizes relevant characteristics of the system components to build a global view and presents particular examples for different architectures (PowerPC and x86) ad operating systems (based on L4 microkernel and Linux kernel). Our evaluations show that typical optimizations on a specific embedded environment reduce the code size by up to 54%
