[llvm-commits] PATCH: Add CHECK-FIRST/LAST to FIleCheck

[Argyris Kyrtzidis]

Actually, using these directives is not flexible enough, e.g you can't  
use them to verify that the output is only one line.

I attached a new patch that adds 2 command lines instead:

   -empty-before    - Nothing comes before the first check
   -empty-after      - Nothing comes after the last check

If you want to make sure that the only output is the check line, you  
do something like:

// RUN: FileCheck -empty-before -empty-after
// CHECK: foo

Ok to go in ?
