<div class="doc_subsubsection">Aligned Data</div>
<div class="doc_text">
<p>In version 1.3, certain data items were aligned to 32-bit boundaries. In
version 1.4, alignment of data was done away with completely. The need for
alignment has gone away and the only thing it adds is bytecode file size
overhead. In most cases this overhead was small. However, in functions with
large numbers of format 0 instructions (GEPs and PHIs with lots of parameters)
or regular instructions with large valued operands (e.g. because there's just
a lot of instructions in the function) the overhead can be extreme. In one
test case, the overhead was 44,000 bytes (34% of the total file size).
Consequently in release 1.4, the decision was made to eliminate alignment
altogether.</p>
<p>In version 1.3 format, the following bytecode constructs were aligned (i.e.
they were followed by one to three bytes of padding):</p>
<ul>
<li>All blocks.</li>
<li>Instructions using the long format (format 0).</li>
<li>All call instructions that called a var args function.</li>
<li>The target triple (a string field at the end of the module block).</li>
<li>The version field (immediately following the signature).</li>
</ul>
<p>None of these constructs are aligned in version 1.4</p>
