  77. <dd><p>One of those features must be always present. 

  78. The feature that is present determines which flavor of m68k is

  79. used.  The feature that is present should contain registers

  80. &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;,

  85. <dd><p>This feature is optional.  If present, it should contain registers

  86. &lsquo;<samp>fp0</samp>&rsquo; through &lsquo;<samp>fp7</samp>&rsquo;, &lsquo;<samp>fpcontrol</samp>&rsquo;, &lsquo;<samp>fpstatus</samp>&rsquo; and

  87. &lsquo;<samp>fpiaddr</samp>&rsquo;.

  88. </p>

  89. <p>Note that, despite the fact that this feature&rsquo;s name says

  90. &lsquo;<samp>coldfire</samp>&rsquo;, it is used to describe any floating point registers.

  91. The size of the registers must match the main m68k flavor; so, for

  92. example, if the primary feature is reported as &lsquo;<samp>coldfire</samp>&rsquo;, then

  93. 64-bit floating point registers are required.
