I'm curious who could be a mentor for such a project?
I think the reviewer for most of the patches for CodeGen so far was
John McCall exclusively since he's pretty much the only person
familiar with the codebase in question.
I'm afraid the stream of patches from me and Reid is already close to
John's available capacity.
I'm very not sure if John can also allocate time for a GSoC student.
