<p>The current metadata format is very simple. <tt>!tbaa.struct</tt> metadata nodes
are a list of operands which are in conceptual groups of three. For each
- group of three, the first operand gives the byte offset of a field in address
- units, the second gives its size in address units, and the third gives its
+ group of three, the first operand gives the byte offset of a field in bytes,
+ the second gives its size in bytes, and the third gives its
tbaa tag. e.g.:</p>
<div class="doc_code">
</pre>
</div>
-<p>This describes a struct with two fields. The first is at offset 0 address units
- with size 4 address units, and has tbaa tag !1. The second is at offset 8 address
- units and has size 4 address units and has tbaa tag !2.</p>

<p>Note that the fields need not be contiguous. In this example, there is a
4 byte gap between the two fields. This gap represents padding which
