 <h5>Overview:</h5>

 <p>A packed type is a simple derived type that represents a vector
 of elements.  Packed types are used when multiple primitive data 
 are operated in parallel using a single instruction (SIMD). 
 A packed type requires a size (number of
 elements) and an underlying primitive data type.  Packed types are
 considered <a href="#t_firstclass">first class</a>.</p>

 <p>The number of elements is a constant integer value, elementtype may
 be any integral or floating point type.</p>

+<h5>Overview:</h5>
+
+<p>Opaque types are used to represent unknown types in the system.  This
+corresponds (for example) to the C notion of a foward declared structure type.
+In LLVM, opaque types can eventually be resolved to any type (not just a
+structure type).</p>
