@monster Hmmm... I assume the generated intrinsic ASM is bundled in one of the Windows SDK libs then... But I have no idea which one
That means you'd have to add some .lib file to the linking options... That still would make your application OS-agnostic. Have you tried using the appearently truly instrinsic `InterlockedExchangeAdd64_nf` delcared in `<intrin.h>`? Although on the msdn page it states that the NoFence variants only apply for ARM architectures and you should the regular `InterlockedExchangeAdd64` instead.
