The RISC-V backend will ship as an official target in the 9.0 release, due the end of August. This talk will give a brief overview of the current status, but primarily focus on elaborating on the development and testing process, picking out lessons to be learned for other backends and for the LLVM community as a whole. Which aspects of our methodology should others adopt? Are there opportunities to improve LLVM to make it easier to bring up new backends? Or opportunities to better share tests? How can we make it easier for language frontends like Rust to support new targets?
