Function std::intrinsics::atomic_xor_relaxed

pub unsafe extern "rust-intrinsic" fn atomic_xor_relaxed<T>(    dst: *mut T,     src: T) -> T where    T: Copy, 

Bitwise xor with the current value, returning the previous value.

The stabilized version of this intrinsic is available on the atomic types via the fetch_xor method by passing Ordering::Relaxed as the order. For example, AtomicBool::fetch_xor.
