Good question! This is my day job! Builds are looking pretty green! https://clangbuiltlinux.github.io/ https://clangbuiltlinux.github.io/ X86_64 required the implementation of ASM goto, which we just shipped. You'll need to build clang from source, but the feature will be in clang-9.0 release. Other arches should build with clang-8 (technically x86_64 will build pre 4.19 kernels) but we shipped pixel 2 kernels w/ clang-4.0 so older Clang's may work depending on your target arch/tree/configs.
