Yes although I've not had chance to upload any related patches for a while.  I started digging into the code generation side of things and then hit issues with generating slightly worse code due to code paths that relied on bogus behaviour.  I was hoping to get it finished in time for LLVM 19 but I don't think that's realistic now but I'll create PRs for what I have.
