          The generic type <type>gentype</type> is used to indicate the built-in data types
          <type>char</type>, <type>uchar</type>, <type>short</type>, <type>ushort</type>,
          <type>int</type>, <type>uint</type>, <type>long</type>, <type>ulong</type>,
          <type>float</type>, or <type>double</type>.

        <para>
          The generic type name <type>gentype<replaceable>n</replaceable></type>
          represents <replaceable>n</replaceable>-element vectors of <type>gentype</type>
          elements. The suffix <replaceable>n</replaceable> is also used in the
          function names (i.e.  <function>vload<replaceable>n</replaceable></function>,
          <function>vstore<replaceable>n</replaceable></function>, etc.), where
          <replaceable>n</replaceable> = 2, 3, 4, 8, or 16.
