----------------
I don't understand this line, this is the same run as the first line, but for the check-prefix. The intent is not clear. 
Note that "CHECK" is the default prefix, used by the first run. But "-LABEL" is a "magic" suffix for FileCheck. So "CHECK-LABEL" is already used by the first check!
See `The “CHECK-LABEL:” directive` section here: http://llvm.org/docs/CommandGuide/FileCheck.html
