<h5 class="subsubsection">3.6.4.4 Input Section and Garbage Collection</h5>

<p><a name="index-KEEP-411"></a><a name="index-garbage-collection-412"></a>When link-time garbage collection is in use (&lsquo;<samp><span class="samp">--gc-sections</span></samp>&rsquo;),
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>.
