[llvm-dev] GSoC Interested student

Hi Hamilton,

first, apologies for not responding to your initial mail. (I got it on
the anl.gov email but just forgot the reply, ...)

I'm glad you took the initiative to work on a bug and TODO!

Wrt. your question, I guess we should just ignore the runtime function
pretending it is something different (for now). It should not happen to
often (I hope) and this is more of a protection agains accidental
miscompilation when people experiment with the runtime.

@Stefanos
Correct, we need more structure. I started a dashboard but I got
distracted. I will create a google doc with tasks today and share it
with people.

Cheers,
  Johannes
