|
|
</p>
|
|

|
|
</pre></div>

<h4 class="subheading">ELF Version</h4>
|
|
|
|
<a name="index-size-directive-_0028ELF-version_0029"></a>
|
|
<p>For ELF targets, the <code>.size</code> directive is used like this:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">.size <var>name</var> , <var>expression</var>
|
|
</pre></div>
|
|
|
|
<p>This directive sets the size associated with a symbol <var>name</var>.
|
|

|
|
