Unless we find a good reason to make an extra effort to make these mismatches work (in an undefined way, at that), my preferred choice would be to fail. Debugging such a mismatch in a GPU code leading to subtle errors at runtime will be a rather terrible experience, and I'd rather catch it at compile time.

However, the fact that LLVM does not complain about such mismatch suggests that I may be missing something.

@nikic  -- would you happen to have thoughts/suggestions on this? Do we need to handle mismatches between the function prototype and the call site? Or can we consider them to be an error?
