Thanks Milind for the great suggestions. Try to follow alone the tutorial
and see if you can create a loop pass.
On top of that I would suggest to also get familiar with
1. The LoopNest class
     - llvm/include/llvm/Analysis/LoopNestAnalysis.h
     - llvm/lib/Analysis/LoopNestAnalysis.cpp
2. Different PassAdaptor classes (e.g. FunctionToLoopPassAdaptor)
     - llvm/include/llvm/Transforms/Scalar/LoopPassManager.h

Please feel free to email me or Ettore if you encounter any blockers, or
have further questions.

  Hi Milind,

  Welcome to LLVM, we're all happy to see people wanting to get involved!

  First of all, it would be good if you could talk about the project with
  the mentors. If only I knew their e-mail addresses to CC them, but I
  You can try to search and maybe have more luck.

  Now, the way I understand this project is that it doesn't have to much
  with the loop nest optimization per se, rather, changing the
  structure of loop optimizations. To that end, I think that you'd want to
  understand how loop optimizations work in LLVM
  (not algorithmically but structurally), understand the role of pass
  managers and whatever legacy is being left.

  I'd propose that a good place to start is this:
  It presents a lot of important things and the bigger part of this video
  is a tutorial.
  Also, I recommend this: https://www.youtube.com/watch?v=QpvZt9w-Jik

  Kind regards,
