Streamline Ahead-of-Time SYCL CPU Device Implementation through Bypassing SPIR-V

Published: 18 April 2023 Publication History

Abstract

Here we present the design and implementation of our LLVM-based Ahead-Of-Time (AOT) SYCL CPU device without using SPIR-V, known as non-SPIRV CPU device. Our design of non-SPIRV CPU device is intended to highlight a general SYCL CPU implementation that aims for both debuggability and performance. Contributions:
• Streamline compiler optimization pipeline by integrating kernel optimizations and transformations into LLVM C++ pipeline.
• Eliminate SPIR-V IR generation during the CPU device code compilation and leverage LLVM IR from compiler front-end directly to reduce compilation overhead and preserve IR information including debug info, among LLVM passes.
