Polly - First successful optimizations - How to proceed?

Polly, the LLVM Polyhedral Optimizer, was presented one year ago. At that point, only the basic infrastructure was in place and many important parts not even started. Even though Polly is still more research than production quality, we made big improvements during the last 12 months. Polly itself moved to the LLVM infrastructure with Bugtracker, Buildbot and VCS. It can now conveniently be loaded into clang as part of clang -O3. We also implemented automatic SIMD and OpenMP code generation and we created a bridge to the external PoCC optimizer. With PoCC and Polly, we were able to compile and _optimize_ the first benchmarks fully automatically and have shown significant improvements over clang -O3. In this talk we give a detailed update about the current status and want to present ideas on how to move further. These will include both research relevant ideas like automatic OpenCL code generation as well as concepts on how to develop robust loop transformations and vectorization for mainstream use. http://polly.grosser.es
