Yes, callbr is part of the discussion on removing proc-point splitting! 

Soon there will be an announcement about a new working group dedicated to LLVM issues such as this one on this mailing list. Anyone interested is welcome to join our meetings.

We're currently gathering our notes together first, but you can have a look here for a preview: https://gitlab.haskell.org/ghc/ghc/wikis/commentary/compiler/LLVM-Backend-Optimization

Could this be used to avoid proc-point splitting?

Thanks
