<dl compact="compact">
<dt><code>&lsquo;<samp>org.gnu.gdb.m68k.core</samp>&rsquo;</code></dt>

<dt><code>&lsquo;<samp>org.gnu.gdb.fido.core</samp>&rsquo;</code></dt>
<dd><p>One of those features must be always present. 
The feature that is present determines which flavor of m68k is
used.  The feature that is present should contain registers
&lsquo;<samp>d0</samp>&rsquo; through &lsquo;<samp>d7</samp>&rsquo;, &lsquo;<samp>a0</samp>&rsquo; through &lsquo;<samp>a5</samp>&rsquo;, &lsquo;<samp>fp</samp>&rsquo;,
&lsquo;<samp>sp</samp>&rsquo;, &lsquo;<samp>ps</samp>&rsquo; and &lsquo;<samp>pc</samp>&rsquo;.
</p>
</dd>
<dt><code>&lsquo;<samp>org.gnu.gdb.coldfire.fp</samp>&rsquo;</code></dt>
<dd><p>This feature is optional.  If present, it should contain registers
&lsquo;<samp>fp0</samp>&rsquo; through &lsquo;<samp>fp7</samp>&rsquo;, &lsquo;<samp>fpcontrol</samp>&rsquo;, &lsquo;<samp>fpstatus</samp>&rsquo; and
&lsquo;<samp>fpiaddr</samp>&rsquo;.
</p>
<p>Note that, despite the fact that this feature&rsquo;s name says
&lsquo;<samp>coldfire</samp>&rsquo;, it is used to describe any floating point registers.
The size of the registers must match the main m68k flavor; so, for
example, if the primary feature is reported as &lsquo;<samp>coldfire</samp>&rsquo;, then
64-bit floating point registers are required.
