Discussion:

I'm looking at 32.5 [atomics] and can't really make sense of a couple of things.

Firstly, there appears to be a typo in the <cstdatomic> synopsis:

The atomic_exchange overload taking an atomic_address is missing the second parameter: 

void* atomic_exchange(volatile atomic_address*);

should be 

void* atomic_exchange(volatile atomic_address*, void*);

Note, that this is not covered by 880(i) "Missing atomic exchange parameter", which only talks about the atomic_bool.

Proposed resolution:

Change the synopsis in 32.5 [atomics]/2: 

void* atomic_exchange(volatile atomic_address*, void*);
