The High-Level Optimizer (HLO) is a key part of the compiler technology that enabled Itanium™ and Itanium™2 processors deliver leading floating-point performance at their introduction. In this paper, we discuss the design and implementation experience in integrating diverse optimizations in the HLO module. In particular, we describe decisions made in the design of HLO targeting Itanium processor family. We provide empirical data to validate the design decisions. Since HLO was implemented in a production compiler, we made certain engineering trade-offs. We discuss these trade-offs and outline key learning derived from our experience. © Springer-Verlag Berlin Heidelberg 2003.
