vcunat's review: - let's not switch the default versions of llvm* for now - the only changes I see is adding python to clang's buildInputs and using the big so-file as discussed in #12759 (BUILD_SHARED_LIBS -> LLVM_LINK_LLVM_DYLIB) - in future it will be nice to split libLLVM into a separate output
