title: What is the difference between load/store relaxed atomic and normal variable?
body: <p>As I see from a test-case: <a href="https://godbolt.org/z/K477q1" rel="nofollow noreferrer">https://godbolt.org/z/K477q1</a></p>
  <p>The generated assembly load/store atomic relaxed is the same as the normal variable: ldr and str</p>
  <p>So, is there any difference between relaxed atomic and normal variable?</p>
