LLVM Compiler for RISC-V Architecture : A Unique Approach to Vectorization, Paperback by Bataev, Alexey, ISBN 9798868821684, ISBN-13 9798868821684, Brand New, Free shipping in the US

This book offers a comprehensive introduction to the RISC-V RVV extension and its integration with LLVM-based compilers. It covers the LLVM VPlan-based Loop Vectorizer and SLP Vectorizer, along with additional insights into the clang frontend, OpenMP support, and RVV-specific clang directives provided by SiFive.

Given the limited information currently available on RVV and its support in modern compilers, this book fills a crucial gap. RVV introduces a unique approach to vectorization—Vector Length Agnostic (VLA) vectorization—which stands out from the fixed vectors of x86 and the runtime-defined, yet fixed, ARM-based SVE and SVE2 extensions.

Readers will gain an understanding of RVV-specific VLA-based vectorization support in LLVM-based compilers, which are still under development. Th also provides early insights into the ongoing support for RVV in LLVM.

What You\'ll Learn

• Gain foundational knowledge of RISC-V and the RVV extension.
• Learn design and implementation of LLVM vectorizers.
• Learn to optimize performance with RVV-specific clang directives.
• Explore the unique Vector Length Agnostic (VLA) vectorization.
• Discover the differences between RVV and other vector extensions.
