<p>This directive is used to set the size associated with a symbol.

<p><a name="index-g_t_0040code_007bsize_007d-directive-_0028COFF-version_0029-470"></a>For COFF targets, the <code>.size</code> directive is only permitted inside
|
||
|
|
<code>.def</code>/<code>.endef</code> pairs. It is used like this:
|
||
|
|
|
||
|
|
<pre class="smallexample"> .size <var>expression</var>
|
||
|
|
</pre>
|

|
|
<p><a name="index-g_t_0040code_007bsize_007d-directive-_0028ELF-version_0029-471"></a>For ELF targets, the <code>.size</code> directive is used like this:
|
||
|
|
|
||
|
|
<pre class="smallexample"> .size <var>name</var> , <var>expression</var>
|
||
|
|
</pre>
|
||
|
|
<p>This directive sets the size associated with a symbol <var>name</var>.
|
||
|
|
The size in bytes is computed from <var>expression</var> which can make use of label
|
||
|
|
arithmetic. This directive is typically used to set the size of function
|
||
|
|
symbols.
