74<p>When link-time garbage collection is in use (&lsquo;<samp>--gc-sections</samp>&rsquo;),
75it is often useful to mark sections that should not be eliminated.
76This is accomplished by surrounding an input section&rsquo;s wildcard entry
77with <code>KEEP()</code>, as in <code>KEEP(*(.init))</code> or
78<code>KEEP(SORT_BY_NAME(*)(.ctors))</code>.
