--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
CCing C++ committee members.
Requiring that any odr-uses of thread_local vars which have static
initialization (which strongly happens before any dynamic initialization) would
dynamically initialize all thread_local variables in the same TU declared
before such vars would have serious ABI and performance effects for no useful
gains.
