Hello LLVM Developers,

I have written a small document explaining IPRA in LLVM. Please find it here https://docs.google.com/document/d/1v-R7gB7Or4bPn0LW7d-yb1yla8jK3DVmTJNFVNYNu6k/edit?usp=sharing

If you feel any more information just mail me I will be happy to help. Anybody is looking to implement other approaches then please feel free to have discussion.
