Abstract

This is a crash course targeted to people doing development work in the Open64 Compiler. The course is organized based on the architecture and features of the compiler. Topics include the WHIRL IR, the global scalar optimizer, the loop nest optimizer, the code generator, inter-procedural analysis and optimization and inlining. The overall approach used in the major components of the compiler will be presented. The global scalar optimizer will be covered in more depth so as to bring forth the concepts behind its unique SSA-based optimization approach. Participants are assumed to have prior knowledge on compiler implementation and program optimization. The goal of this course is to enable the students to be better prepared to work effectively on the Open64 Compiler.
