Yes, sorry, I should have mentioned that it currently supports System V ABI only. Thanks for pointing this.

This only works for the sysv abi (unices), not on windows, because
parameters come in different registers there.  See
https://docs.microsoft.com/en-us/cpp/build/x64-calling-convention for
windows' calling convention; probably not hard to work around with
macros (though cmpxchg might require some extra fanangling).
