--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
__builtin_thread_pointer is potentially trapping (which is the root of the
problem). Does GCC know about that? It also results in a load followed by an
add, instead of a single load, I think. Using the __segfs or __seggs namespaces
looks preferable to me.
