+<h5>Overview:</h5>
+<p>The packed structure type is used to represent a collection of data members
+together in memory.  There is no padding between fields.  Further, the alignment
+of a packed structure is 1 byte.  The elements of a packed structure may
+be any type that has a size.</p>
+<p>Structures are accessed using '<tt><a href="#i_load">load</a></tt>
+and '<tt><a href="#i_store">store</a></tt>' by getting a pointer to a
+field with the '<tt><a href="#i_getelementptr">getelementptr</a></tt>'
+instruction.</p>
