<h3>
<a name="Polly">Polly</a>
</h3>
<div>
<p><a href="http://polly.llvm.org/">Polly</a> is an <em>experimental</em>
optimizer for data locality and parallelism. It currently provides high-level
loop optimizations and automatic parallelisation (using the OpenMP run time).
Work in the area of automatic SIMD and accelerator code generation was
started.
<p>Within the LLVM 3.1 time-frame there were the following highlights:</p>
<ul>
<li>Polly became an official LLVM project</li>
<li>Polly can be loaded directly into clang (Enabled by '-O3 -mllvm -polly'
)</li>
<li>An automatic scheduling optimizer (derived from <a
href="http://pluto-compiler.sourceforge.net/">Pluto</a>) was integrated. It
performs loop transformations to optimize for data-locality and parallelism.
The transformations include, but are not limited to interchange, fusion,
fission, skewing and tiling.
</li>
</ul>
