<h4 class="subsection">6.34.6 IA-64 Variable Attributes</h4>

<p>The IA-64 back end supports the following variable attribute:
</p>
<dl compact="compact">
<dt><code>model (<var>model-name</var>)</code></dt>
<dd><a name="index-model-variable-attribute_002c-IA_002d64"></a>

<p>On IA-64, use this attribute to set the addressability of an object.
At present, the only supported identifier for <var>model-name</var> is
<code>small</code>, indicating addressability via &ldquo;small&rdquo; (22-bit)
addresses (so that their addresses can be loaded with the <code>addl</code>
instruction).  Caveat: such addressing is by definition not position
independent and hence this attribute must not be used for objects
defined by shared libraries.
