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 are looking for volunteers to present (~20 minutes) at this meetup. 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.
