<h5 class="subsubsection">Input section and garbage collection</h5>



   <p>When link-time garbage collection is in use (<code>--gc-sections</code>),

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(*)(.ctors))</code>.
