[PATCH] D16928: [OpenCL] Apply missing restrictions for Blocks in OpenCL v2.0

[Mats Petersson via cfe-commits]

MatsPetersson added a comment.

I think adding printf as a builtin function is a good idea.

If not, I feel that the error message should distinguish between (for example):

  int printf(global char* fmt, ...);

and

  void myfunc(int n, ...);

since the former is "incorrect prototype of printf" and the latter is "not a valid opencl function".
