+<h5>Syntax:</h5>
+
+<pre>
+  <result> = insertelement <n x <ty>> <val>, <ty> <elt&gt, uint <idx>    <i>; yields <n x <ty>></i>
+</pre>
+
+<h5>Overview:</h5>
+
+<p>
+The '<tt>insertelement</tt>' instruction inserts a scalar
+element into a packed vector at a specified index.
+</p>
+
+
+<h5>Arguments:</h5>
+
+<p>
+The first operand of an '<tt>insertelement</tt>' instruction is a
+value of <a href="#t_packed">packed</a> type.  The second operand is a
+scalar value whose type must equal the element type of the first
+operand.  The third operand is an index indicating the position at
+which to insert the value.  The index may be a variable.</p>
+
+<h5>Semantics:</h5>
+
+<p>
+The result is a packed vector of the same type as <tt>val</tt>.  Its
+element values are those of <tt>val</tt> except at position
+<tt>idx</tt>, where it gets the value <tt>elt</tt>.  If <tt>idx</tt>
+exceeds the length of <tt>val</tt>, the results are undefined.
+</p>
+
+<h5>Example:</h5>
+
+<pre>
+  %result = insertelement <4 x int> %vec, int 1, uint 0    <i>; yields <4 x int></i>
+</pre>
