The llvm-3.2 release will officially support polly...

​http://llvm.org/docs/ReleaseNotes.html

It would be helpful to add polly support to the existing llvm-3.2 package as it will allow debugging of ​http://llvm.org/bugs/show_bug.cgi?id=14140 by the Apple programmers.

The instructions for building polly under llvm are at ​http://polly.llvm.org/get_started.html and will require an isl and cloog-isl package as well as gmp. As I mentioned before in the gcc48 tickets MacPorts really should provide isl/cloog-isl because ppl/cloog-ppl support is deprecated now in FSF gcc trunk.I would also note that Polly does work in llvm-3.2 under clang by using...
