<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.
</p>
<p>
<code class="function">vstore3</code>, and <code class="function">vstore_half3</code> write
<code class="varname">x</code>, <code class="varname">y</code>, <code class="varname">z</code> components from a
3-component vector to address (<code class="varname">p</code> + (<code class="varname">offset</code> * 3)).
