Hi David,

In the very nearby future (after I switch SPARC64 and MIPS to
libcompiler_rt), it should be possible to safely use C11's <stdatomic.h>
on all supported architectures. The C11 interface allows any operation
to be combined with any type of barrier.

Maybe we should simply migrate this code to use <stdatomic.h> then?

Greetings,
