| |
| <p><a name="index-KEEP-473"></a><a name="index-garbage-collection-474"></a>When link-time garbage collection is in use (‘<samp><span class="samp">--gc-sections</span></samp>’), |
| it is often useful to mark sections that should not be eliminated. |
| This is accomplished by surrounding an input section's wildcard entry |
| with <code>KEEP()</code>, as in <code>KEEP(*(.init))</code> or |
| <code>KEEP(SORT_BY_NAME(*)(.ctors))</code>. |
