to the low 16 bits of an absolute expression.

   <p>The &lsquo;<samp><span class="samp">.desc</span></samp>&rsquo; directive is not available when <samp><span class="command">as</span></samp> is
configured for COFF output; it is only for <code>a.out</code> or <code>b.out</code>
object format.  For the sake of compatibility, <samp><span class="command">as</span></samp> accepts
it, but produces no output, when configured for COFF.
