        <h2>Notes</h2>
        <p>
          The generic type <span class="type">gentype</span> is used to indicate the built-in data types
          <span class="type">char</span>, <span class="type">uchar</span>, <span class="type">short</span>, <span class="type">ushort</span>,
          <span class="type">int</span>, <span class="type">uint</span>, <span class="type">long</span>, <span class="type">ulong</span>,
          <span class="type">float</span>, or <span class="type">double</span>.
        </p>
        <p>
          The generic type name <span class="type">gentype<em class="replaceable"><code>n</code></em></span>
          represents <em class="replaceable"><code>n</code></em>-element vectors of <span class="type">gentype</span>
          elements. The suffix <em class="replaceable"><code>n</code></em> is also used in the
          function names (i.e.  <code class="function">vload<em class="replaceable"><code>n</code></em></code>,
          <code class="function">vstore<em class="replaceable"><code>n</code></em></code>, etc.), where
          <em class="replaceable"><code>n</code></em> = 2, 3, 4, 8, or 16.
        </p>
        <p>
          Vector Data Load and Store Functions allow
          you to read and write vector types from a pointer to memory.
        </p>
        <p>
            The suffix <code class="varname">n</code> in the function names 
            (i.e. vload<code class="varname">n</code>, vstore<code class="varname">n</code> etc.) 
            represent <code class="varname">n</code>-element 
            vectors, where <code class="varname">n</code> = 2, 3, 4, 8 or 16.
        </p>
        <p>
          
          The results of vector data
          load and store functions are undefined if the address being read from or written to is
          not correctly aligned. The pointer argument <code class="varname">p</code> can be a pointer to
          <a class="citerefentry" href="global.html"><span class="citerefentry"><span class="refentrytitle">global</span></span></a>,
          <a class="citerefentry" href="local.html"><span class="citerefentry"><span class="refentrytitle">local</span></span></a>, or
          <a class="citerefentry" href="private.html"><span class="citerefentry"><span class="refentrytitle">private</span></span></a>
          memory for store functions. The pointer argument
          <code class="varname">p</code> can be a pointer to global, local, 
          constant or private memory for load functions.
        </p>
        <p>
            NOTE: The vector data load and store functions 
            variants that take pointer arguments which 
            point to the generic address space are also supported.
        </p>
        <p>
          When extended by the
          <a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a> extension,
          the generic type <span class="type">gentype<em class="replaceable"><code>n</code></em></span> is extended to
          include <span class="type">half</span>, <span class="type">half2</span>, <span class="type">half3</span>, <span class="type">half4</span>,
          <span class="type">half8</span>, and <span class="type">half16</span>.
        </p>
        <p>
            When the half extension is enabled, the address computed as
            (<code class="varname">p</code> + (<code class="varname">offset</code> * <code class="varname">n</code>)) must be
            16-bit aligned.
