In particular, can't Uros' patch be considered as such here? Frankly, t

That's a fairly dangerous hack in my opinion, in particular this breaks the

represented in a HOST_WIDE_INT, we expand this to a const_int.
The expansion from tree to rtl happens in expand_builtin_atomic_store. And as
with most of our builtins, we then pass off the rtl to another routine for
expansion. W
