7.17.7.5 says (https://port70.net/~nsz/c/c11/n1570.html#7.17.7.5)

> 1 The following operations perform arithmetic and bitwise computations. All of these operations are applicable to an object of any atomic integer type. None of these operations is applicable to atomic_bool.

If I understand it correctly, this wording is intended to restrict these 
operations to integers types only. I.e. they shall not be applied to 
atomic pointer types. Is that correct?

Later 7.17.7.5 also says

> 3 For address types, the result may be an undefined address, but the operations otherwise have no undefined behavior.

However, I was unable to find any mention of "address types" anywhere in 
the standard. What types are "address types"?
