+
+
+<h5>Arguments:</h5>
+
+<p>
+The first operand of an '<tt>extractvalue</tt>' instruction is a
+value of <a href="#t_struct">struct</a> or <a href="#t_array">array</a>
+type.  The operands are constant indicies to specify which value to extract

+<h5>Arguments:</h5>
+
+<p>
+The first operand of an '<tt>insertvalue</tt>' instruction is a

+The second operand is a first-class value to insert.
+type of the first operand.  The following operands are constant indicies
+indicating the position at which to insert the value in the same manner as
+indicies in a
+'<tt><a href="#i_getelementptr">getelementptr</a></tt>' instruction.
+The value to insert must have the same type as the value identified
+by the indicies.
+
+<h5>Semantics:</h5>
+
+<p>
+The result is an aggregate of the same type as <tt>val</tt>.  Its
+value is that of <tt>val</tt> except that the value at the position
