I also recommend you to make the use of Travis CI.

My last commit ask Travis CI to build LLVM#. Travis CI will only send you email when you pushed uncompilable code(rather than simply build fail).

@ice1000 can you squash merge into a single commit? Also, is there a reason why you removed "this." from your changes?

is there a reason why you removed "this." from your changes?

Can you do this as the merger? I've seen the github blog and it says there's a button like this
