<h4 class="subsection">Output section discarding</h4>



   <p>The linker will not create output section which do not have any

contents.  This is for convenience when referring to input sections that

may or may not be present in any of the input files.  For example:

<pre class="smallexample">     .foo { *(.foo) }

     </pre>



<p>will only create a <code>.foo</code> section in the output file if there is a

<code>.foo</code> section in at least one input file.



   <p>If you use anything other than an input section description as an output

section command, such as a symbol assignment, then the output section

will always be created, even if there are no matching input sections.



   <p>The special output section name <code>/DISCARD/</code> may be used to discard

input sections.  Any input sections which are assigned to an output

section named <code>/DISCARD/</code> are not included in the output file.
