@nathanchance reports in https://github.com/ClangBuiltLinux/linux/issues/1512
that

  // clang x.c
  register long current_stack_pointer asm("rsp");
  void vmcs_set_bits() {
    asm goto("" : "+r"(current_stack_pointer) : : : do_exception);
  do_exception:;
  }

now seems to be crashing as a result of this change.
