What would be the meaning of CHECK-NEXT in this situation? Because that would to me, match an empty string, expected to be on the next line. The next empty string after foo is trivially on the same line as foo. Note that CHECK-NEXT searches for the next instance of the specified string, and fails if it finds it anywhere other than on the next line, rather than just searching the next line for the specified string.
