+<pre>&lt;result&gt; = vsetint &lt;op&gt;, &lt;n x &lt;ty&gt;&gt; &lt;var1&gt;, &lt;var2&gt;   <i>; yields &lt;n x bool&gt;</i>
+</pre>
+
+<h5>Overview:</h5>
+
+<p>The '<tt>vsetint</tt>' instruction takes two integer vectors and
+returns a vector of boolean values representing, at each position, the
+result of the comparison between the values at that position in the
+two operands.</p>
+
+<h5>Arguments:</h5>
+
+<p>The arguments to a '<tt>vsetint</tt>' instruction are a comparison
+operation and two value arguments.  The value arguments must be of <a
+href="#t_integral">integral</a> <a href="#t_packed">packed</a> type,
+and they must have identical types.  The operation argument must be
+one of <tt>eq</tt>, <tt>ne</tt>, <tt>slt</tt>, <tt>sgt</tt>,
+<tt>sle</tt>, <tt>sge</tt>, <tt>ult</tt>, <tt>ugt</tt>, <tt>ule</tt>,
+<tt>uge</tt>, <tt>true</tt>, and <tt>false</tt>.  The result is a
+packed <tt>bool</tt> value with the same length as each operand.</p>
+
+<h5>Semantics:</h5>
+
+<p>The following table shows the semantics of '<tt>vsetint</tt>'.  For
+each position of the result, the comparison is done on the
+corresponding positions of the two value 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>vsetint
+slt <4 x unsigned> %x, %y</tt> does an elementwise <i>signed</i>
+comparison of <tt>%x</tt> and <tt>%y</tt>.</p>

+<h5>Overview:</h5>
+
+<p>The '<tt>vsetfp</tt>' instruction takes two floating point vector
+arguments and returns a vector of boolean values representing, at each
+position, the result of the comparison between the values at that
+position in the two operands.</p>
+
+<h5>Arguments:</h5>
+
+<p>The arguments to a '<tt>vsetfp</tt>' instruction are a comparison
+operation and two value arguments.  The value arguments must be of <a
+href="t_floating">floating point</a> <a href="#t_packed">packed</a>
+type, and they must have identical types.  The operation argument must
+be one of <tt>eq</tt>, <tt>ne</tt>, <tt>lt</tt>, <tt>gt</tt>,
+<tt>le</tt>, <tt>ge</tt>, <tt>oeq</tt>, <tt>one</tt>, <tt>olt</tt>,
+<tt>ogt</tt>, <tt>ole</tt>, <tt>oge</tt>, <tt>ueq</tt>, <tt>une</tt>,
+<tt>ult</tt>, <tt>ugt</tt>, <tt>ule</tt>, <tt>uge</tt>, <tt>o</tt>,
+<tt>u</tt>, <tt>true</tt>, and <tt>false</tt>.  The result is a packed
+<tt>bool</tt> value with the same length as each operand.</p>
+
+<h5>Semantics:</h5>
+
+<p>The following table shows the semantics of '<tt>vsetfp</tt>' for
+floating point types.  If either operand is a floating point Not a
+Number (NaN) value, the operation is unordered, and the value in the
+first column below is produced at that position.  Otherwise, the
+operation is ordered, and the value in the second column is
+produced.</p>

+<h5>Overview:</h5>
+
+<p>
+The '<tt>vselect</tt>' instruction chooses one value at each position
+of a vector based on a condition.
+</p>
+
+
+<h5>Arguments:</h5>
+
+<p>
+The '<tt>vselect</tt>' instruction requires a <a
+href="#t_packed">packed</a> <tt>bool</tt> value indicating the
+condition at each vector position, and two values of the same packed
+type.  All three operands must have the same length.  The type of the
+result is the same as the type of the two value operands.</p>
+
+<h5>Semantics:</h5>
+
+<p>
+At each position where the <tt>bool</tt> vector is true, that position
+of the result gets its value from the first value argument; otherwise,
+it gets its value from the second value argument.
+</p>
+
+<h5>Example:</h5>
+
+<pre>
+  %X = vselect bool &lt;2 x bool&gt; &lt;bool true, bool false&gt;, &lt;2 x ubyte&gt; &lt;ubyte 17, ubyte 17&gt;, 
+    &lt;2 x ubyte&gt; &lt;ubyte 42, ubyte 42&gt;      <i>; yields &lt;2 x ubyte&gt;:17, 42</i>
