+- Initial support for ``asm goto`` statements (a GNU C extension) has been

 Significant Known Problems
 ==========================
 
+Linux Kernel
+============
+
+With support for asm goto, the mainline Linux kernel for x86_64 is now buildable
+(and bootable) with Clang 9.  Other architectures that don't require
+CONFIG_JUMP_LABEL=y such as arm, aarch64, ppc32, ppc64le, (and possibly mips)
+have been supported with older releases of Clang (Clang 4 was first used with
+aarch64).
+
+The Android and ChromeOS Linux distributions have moved to building their Linux
+kernels with Clang, and Google is currently testing Clang built kernels for
+their production Linux kernels.
+
+Further, LLD, llvm-objcopy, llvm-ar, llvm-nm, llvm-objdump can all be used to
+build a working Linux kernel.
+
