LLVM optimisation passes / tables next to code

[David Terei]

Hi Sergiu,

Welcome to the wonderful and painful world of GHC hacking :) If GHC
decides to accept you and for the project you propose then I'd
probably be the mentor. I think this is a good project to get done but
also a risky one. We've had mixed SoC results and have progressively
tried to put students onto more defined and straight forward tasks.

The hacking would also be nearly 100% C++ as its the LLVM code base
you need to change not GHC's so much.

If you're keen on this though I'd suggest you do the following to get
some traction to show you could handle this as a project:

1. Read this bug ticket:
http://hackage.haskell.org/trac/ghc/ticket/4213, I've put a short
explanation of how I'd tackle this task.
2. Talk to the LLVM developers (please CC me on the emails). They will
know if the method I propose are good or not and how keen they are to
accept patches.

Basically your SoC application should include a clear description of
how you'll implement the features needed in LLVM and indication that
the LLVM developers are likely to accept such patches.

Cheers,
David
