RISC-V RVV Specific LLVM-Based Optimizations
摘要
The RISC-V Vector Extension (RVV) version 1.0 comes with some interesting challenges for compiler tools. LLVM tackles these challenges with some clever methods. The main idea behind LLVM’s strategy is using scalable vector types. This concept was first created for ARM’s Scalable Vector Extension (SVE), but it has been adapted successfully for RVV.
