<h3 class="section">Architecture selection</h3>
<p>An <dfn>architecture</dfn> is a type of <small>CPU</small> on which an object file is
to run. Its name may contain a colon, separating the name of the
processor family from the name of the particular <small>CPU</small>.
<p>The command to list valid architecture values is <code>objdump -i</code> (the
second column contains the relevant information).
<p>Sample values: <code>m68k:68020</code>, <code>mips:3000</code>, <code>sparc</code>.
<h4 class="subheading"><code>objdump</code> Architecture</h4>
<p>Ways to specify:
<ol type=1 start=1>
<li>command line option: <code>-m</code> or <code>--architecture</code>
<li>deduced from the input file
</ol>
<h4 class="subheading"><code>objcopy</code>, <code>nm</code>, <code>size</code>, <code>strings</code> Architecture</h4>
<p>Ways to specify:
<ol type=1 start=1>
<li>deduced from the input file
</ol>
<h4 class="subheading">Linker Input Architecture</h4>
<p>Ways to specify:
<ol type=1 start=1>
<li>deduced from the input file
</ol>
<h4 class="subheading">Linker Output Architecture</h4>
<p>Ways to specify:
<ol type=1 start=1>
<li>script command <code>OUTPUT_ARCH</code>
(see <a href="../ld.info/Miscellaneous-Commands.html#Miscellaneous%20Commands">Miscellaneous Commands</a>)
<li>the default architecture from the linker output target
(see <a href="Target-Selection.html#Target%20Selection">Target Selection</a>)
