Idézet: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. The book 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.

Who This Book Is For

✔ For the engineers, who would like to get more info about RISC-V in general and RISC-V Vectorextension particularly.
✔ For the developers, trying to get the performance using RVV.
✔ For LLVM compiler developers, trying or learn more about vectorization support in LLVM.4.
✔ For the students, who learn new about RISC- V, its extensions, interested in compiler development.
