As always, it was great to catch up with people at the RISC-V Summit Europe. I've converted the talk I gave into blog post form - if you have any interest at all in RISC-V vector code generation, read on!

Igalia @igalia.com · May 28

Earlier this month at the RISC-V Summit Europe, we presented an overview of improvements made by to RISC-V vector code generation by RISC-V LLVM contributors over the past few releases. Check out the blog post summary from @lukel97.bsky.social and @asbradbury.org
