--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is atomic store, not atomic load, what do you expect?
The only reason for taking val as a pointer rather than the value itself is
that some values really need to live in memory and the API is generic.  If you
are trying to pass an address of a var that is modified by other threads, it is
just a bug in your source code, you likely want to do an atomic load into a
temporary automatic variable etc. which won't be modified by other threads and
only then atomic_store it.
