We, EPI, SiPearl, and SiFive, have come out with a RFC for RISC-V vector intrinsics. If you are interested in the RISC-V vector intrinsics design, welcome to join the discussion. We have created a github repository for the documents.
In this RFC, we defined the type system, programming interface and naming rules for vector intrinsics in the C language. This document could be used as a reference for RISC-V vector intrinsic implementation in the future.
Currently, there are a few issues under discussion. We need your opinions and feedback about these issues. Besides these issues, welcome any feedback about vector intrinsic design.
