<p>An <em>architecture</em> 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>
<p>The command to list valid architecture values is &lsquo;<samp>objdump -i</samp>&rsquo; (the
second column contains the relevant information).
</p>
<p>Sample values: &lsquo;<samp>m68k:68020</samp>&rsquo;, &lsquo;<samp>mips:3000</samp>&rsquo;, &lsquo;<samp>sparc</samp>&rsquo;.
</p>
<a name="objdump-Architecture"></a>
