Since the last US developers meeting the Polly loop optimization infrastructure has significantly evolved with significant progress
in terms of usability, applicability and compile time. Several regular developers joined our team from different places of the world and several of these started to extend and use Polly in new situations. In the last years both informal Polly meetups as well as officially announced BoFs have taken place at the US developer's meeting as well as EuroLLVM and these have been of great help to coordinate our efforts. As this year several core developers are attending the US developers meeting, we will have again an official BoF to discuss
with the wider LLVM community the impact of the recent changes we made in Polly, Polly's development agenda for the next years as well as its use in the wider LLVM community. Topics of interest might be: integration of Polly into the pass pipeline, interaction with other optimizations (vectorizer, classical loop optimizations), possible uses of Polly analyses, recent compile-time reduction, new optimizations,
