Open Research Compiler for ItaniumTM Processor Family

　

　

　

　

Introduction

The objective of the Open Research Compiler (ORC) project is to provide a leading open source ItaniumTM Processor Family (IA-64) compiler infrastructure to the compiler and architecture research community. This project is a  collaboration between Intel Corp. and Chinese Academy of Sciences. We would like to provide a common infrastructure to encourage and facilitate compiler and architecture research. In the design of ORC, we stress on the following aspects: compatibility to other open source tools, robustness of the entire infrastructure, flexibility and modularity for quick prototyping of novel ideas, and leading performance among ItaniumTM Processor Family open source compilers. We would like to invite researchers to explore all aspects of compiler and architecture research on ORC, e.g. performance-driven optimizations, thread-level parallelism, co-design of software and hardware features, power management, design and implementation of type-safe languages, co-design of static and dynamic compilation, optimizations for memory hierarchies, etc.
