| <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> |
| <!-- only print the extra heading if both COFF and ELF are set --> |
| <h4 class="subheading">ELF Version</h4> |
| |
| <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. |
