+ <p>The <tt>TargetSubtarget</tt> class is used to provide information about the
+ specific chip set being targeted. A sub-target informs code generation of
+ which instructions are supported, instruction latencies and instruction
+ execution itinerary; i.e., which processing units are used, in what order, and
