- <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>
