title: GCC support for Intel AVX instrinsics (dvec.h)
body: <p>Does GCC support <code>dvec.h</code>, and if not, what can I do to port code written for ICC to work with GCC?</p>
  
  <p>I am getting errors:</p>
  
  <pre><code>fatal error: dvec.h: No such file or directory
   #include &lt;dvec.h&gt;
  </code></pre>
  
  <p>Alternatively, GCC cannot find <code>F32vec8</code>.</p>
