The features of the IA64 architecture create new opportunities for link-time optimization. At the same time they complicate the design of a link-time optimizer. This paper examines how to exploit some of the opportunities for link-time optimization and how to deal with the complications. The prototype link-time optimizer that implements the discussed techniques is able to reduce the code size of statically linked programs with 19% and achieves a speedup of 5.4% on average.
