<h5 class="subsubsection">3.6.4.5 Input Section Example</h5>

<p>The following example is a complete linker script.  It tells the linker
to read all of the sections from file <samp><span class="file">all.o</span></samp> and place them at the
start of output section &lsquo;<samp><span class="samp">outputa</span></samp>&rsquo; which starts at location
&lsquo;<samp><span class="samp">0x10000</span></samp>&rsquo;.  All of section &lsquo;<samp><span class="samp">.input1</span></samp>&rsquo; from file <samp><span class="file">foo.o</span></samp>
follows immediately, in the same output section.  All of section
&lsquo;<samp><span class="samp">.input2</span></samp>&rsquo; from <samp><span class="file">foo.o</span></samp> goes into output section
&lsquo;<samp><span class="samp">outputb</span></samp>&rsquo;, followed by section &lsquo;<samp><span class="samp">.input1</span></samp>&rsquo; from <samp><span class="file">foo1.o</span></samp>. 
All of the remaining &lsquo;<samp><span class="samp">.input1</span></samp>&rsquo; and &lsquo;<samp><span class="samp">.input2</span></samp>&rsquo; sections from any
files are written to output section &lsquo;<samp><span class="samp">outputc</span></samp>&rsquo;.

<pre class="smallexample">     SECTIONS {
       outputa 0x10000 :
         {
         all.o
         foo.o (.input1)
         }
       outputb :
         {
         foo.o (.input2)
         foo1.o (.input1)
         }
       outputc :
         {
         *(.input1)
         *(.input2)
         }
     }
</pre>
   <p>If an output section's name is the same as the input section's name
and is representable as a C identifier, then the linker will
automatically see <a href="PROVIDE.html#PROVIDE">PROVIDE</a> two symbols: __start_SECNAME and
__stop_SECNAME, where SECNAME is the name of the section.  These
indicate the start address and end address of the output section
respectively.  Note: most section names are not representable as
C identifiers because they contain a &lsquo;<samp><span class="samp">.</span></samp>&rsquo; character.
