Region-based compilation! Rich support for profiling• New IPF* Optimizations! Predication and analysis! Control and data speculation! Global instruction scheduling! Parameterized machine model• Research Case Study! Resource management during scheduling• Demo of ORC• Release and Future Plans* IPF for Itanium Processor Family in this presentationR®2 ORC TutorialOverview of ORC R®3 ORC TutorialObjectives of ORC• To provide a leading open source IPF (IA-64) compiler infrastructure to the compiler and architecture research community! To encourage compiler and architecture research! To minimize the resource investments for university groups! Performance better than existing IPF open source compilers ! Fair comparison on a common infrastructureR®4 ORC TutorialRequirements for ORC• Robustness! solid research compiler infrastructure• Timing of availability! to enable research in early IPF systems• Flexibility! modularity and clean interface to facilitate prototyping novel ideas• Performance! leading performance among IPF open source compilers! sufficiently high to make research results from this compiler trustworthyR®5 ORC ...
