|
||
|
|
|
||
|
|
<p><a name="index-KEEP-445"></a><a name="index-garbage-collection-446"></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>.
