Foreword

By
Fredrick R. Sporck
Director
IBM Microelectronics Division—PowerPC Products

IBM's reputation for commitment to technology and innovation is legendary in the computer industry. Over the past two decades, IBM has followed this tradition with its dedication to the development and enhancement of RISC architecture.

With the introduction of the PowerPC architecture, IBM has again recognized the need for supporting its products. In response, IBM has prepared The PowerPC Compiler Writer's Guide. Some of the brightest minds from many companies in the fields of compiler and processor development have combined their efforts in this work. A balanced, insightful examination of the PowerPC architecture and the pipelines implemented by PowerPC processors has yielded a guide giving compiler developers valuable insight into the generation of high-performance code for PowerPC processors.

By taking this step, IBM is equipping readers of The PowerPC Compiler Writer's Guide with the power to harness the potential of the PowerPC revolution. Once again, IBM is stepping forward with dedication to its customers and the powerful backing of its cutting-edge architecture.
