(In reply to Dimitry Andric from comment #32)
For the old gcc you will probably have to use the __sync_* builtins as in our
stdatomic.h.  But I think there's a problem with the implementation in
compiler_rt.  Clang generates functions calls to compiler_rt if it can't inline
__c11_atomic_* (e.g. if the architecture only guarantees atomicity if an object
is properly aligned and a given object isn't aligned) so how can compiler_rt
then use __c11_atomic_*?
