static

This function should be invoked to emit atomic cmpxchg for Microsoft's _InterlockedCompareExchange* intrinsics which have the following signature: T _InterlockedCompareExchange(T volatile *Destination, T Exchange, T Comparand);.

Whereas the llvm 'cmpxchg' instruction has the following syntax: cmpxchg *Destination, Comparand, Exchange. So we need to swap Comparand and Exchange when invoking CreateAtomicCmpXchg. That is the reason we could not use the above utility function MakeAtomicCmpXchgValue since it expects the arguments to be already swapped.
