Function std::intrinsics::atomic_xor_relaxed

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

Bitwise xor with the current value, returning the previous value. The stabilized version of this intrinsic is available on the std::sync::atomic types via the fetch_xor method by passing Ordering::Relaxed as the order. For example, AtomicBool::fetch_xor.
