<dt><code>.atmp</code></dt>

</dl>

<p>The <code>.dual</code>, <code>.enddual</code>, and <code>.atmp</code> directives are available only in the Intel syntax mode.
</p>
<p>Both syntaxes allow for the standard <code>.align</code> directive.  However,
the Intel syntax additionally allows keywords for the alignment
parameter: &quot;<code>.align type</code>&quot;, where &lsquo;type&rsquo; is one of <code>.short</code>, <code>.long</code>,
<code>.quad</code>, <code>.single</code>, <code>.double</code> representing alignments of 2, 4,
16, 4, and 8, respectively.
