<p>The &lsquo;<samp>org.gnu.gdb.nios2.cpu</samp>&rsquo; feature is required for Nios II
targets.  It should contain the 32 core registers (&lsquo;<samp>zero</samp>&rsquo;,
&lsquo;<samp>at</samp>&rsquo;, &lsquo;<samp>r2</samp>&rsquo; through &lsquo;<samp>r23</samp>&rsquo;, &lsquo;<samp>et</samp>&rsquo; through &lsquo;<samp>ra</samp>&rsquo;),
&lsquo;<samp>pc</samp>&rsquo;, and the 16 control registers (&lsquo;<samp>status</samp>&rsquo; through
&lsquo;<samp>mpuacc</samp>&rsquo;).
