Could you elaborate on that? I did actually discover that function
needed modification the other day, but converting it to take a
"Function *" seemed to satisfy Clang (and make the implementation
simpler).

My current understanding is that Intrinsic::getDeclaration returns a
Function that *does* have the necessary info
(Function::getFunctionType, though CreateCall can be used directly).

Cheers.

Tim.
