LLVM, Clang, lldb, lld, Polly meetup

This is a casual meetup to get to know people working on LLVM, or Clang, lldb, lld, Polly, ... and exchange experience around those. Or just to learn about them.

We will have a talk from Michael Kruse: "Where to put Polly ? Interactions between Polly and LLVM's other passes."

Polly is an extension for LLVM for polyhedral optimization. Unfortunately what transformations it can perform depends on the form of the IR. Some LLVM passes improve the analyzability for Polly, but others reduce optimization opportunities. What would be the ideal pass pipeline for Polly ?

We are looking for volunteers to present (~20 minutes) at this meetup or the next. This does not have to be a formal presentation: this could be a tutorial, a BoF, a bugfix party, your usage of LLVM, ... Be creative ! If interested, please talk to one of the organizers.
