+ <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>
