[PATCH] D31745: [OpenCL] Added diagnostic for implicit declaration of function in OpenCL

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

What happens if user declared a function without parameter as `void f();` instead of `void f(void)` then try to use it? Will this be treated as implicit declaration and results in an error instead of warning?
