I don't think that's right. LLVM 9 hasn't been branched yet so it should make it in. http://lists.llvm.org/pipermail/llvm-dev/2019-June/133155.html If anyone wants to play around with it before then, we wrote a self-contained script that will build an LLVM toolchain suitable for kernel development: https://github.com/ClangBuiltLinux/tc-build Cheers, Nathan
