Function std::intrinsics::volatile_copy_memoryUnstable

pub unsafe fn volatile_copy_memory<T>(dst: *mut T, src: *const T, count: usize)

Equivalent to the appropriate llvm.memmove.p0i8.0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of min_align_of::<T>()

The volatile parameter parameter is set to true, so it will not be optimized out.
