Title
Design and Analysis of Profile-Based Optimization in Compaq's Compilation Tools for Alpha
Abstract
This paper describes and evaluates the profile-based optimizations in the Compaq C compiler tool chain for Alpha. The optimizations include superblock formation, inlining, commando loop optimization, register allocation, code layout, and switch statement optimization. The optimiza- tions either are extensions of classical optimizations or are restructuring transformations that en- able classical optimizations. Profile-based optimization is highly effective, achieving a 17% speedup over aggressive classical optimization on the SPECInt95 benchmarks. Inlining contrib- utes the most performance and code layout, superblock formation, and loop restructuring are also important.
