<h5>Overview:</h5>
-<p>The '<tt>vset</tt>' instruction returns a vector of boolean

+<p>The arguments to a '<tt>vsetint</tt>' instruction are a comparison
operation and two value arguments. The value arguments must be of <a

-arguments. Note that the signedness of the comparison depends on the
-comparison opcode and <i>not</i> on the signedness of the value
-operands. E.g., <tt>vset lt <4 x unsigned> %x, %y</tt> does an
