<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>
<h5>Syntax:</h5>
<pre> &lt; { &lt;type list&gt; } &gt; <br></pre>
<h5>Examples:</h5>
<table class="layout">
<tr class="layout">
<td class="left">
<tt> &lt; { int, int, int } &gt; </tt><br/>
<tt> &lt; { float, int (int) * } &gt; </tt><br/>
</td>
<td class="left">
a triple of three <tt>int</tt> values<br/>
A pair, where the first element is a <tt>float</tt> and the second element
is a <a href="#t_pointer">pointer</a> to a <a href="#t_function">function</a>
that takes an <tt>int</tt>, returning an <tt>int</tt>.<br/>
