title: micro-benchmark to study the latency of movdir64b instruction
body: <p>I want to study the latency of instruction <code>movdir64b</code> on a system which supports this instruction.</p>
  <p>How can I write a simple micro-benchmark to accomplish this?</p>
  <p>Note: <code>MOVDIR64B</code> reads 64-bytes from the source memory address and performs a 64-byte direct-store operation to the destination address. [Details: https://www.felixcloutier.com/x86/movdir64b]</p>
