New Revision: 195260
URL: http://llvm.org/viewvc/llvm-project?rev=195260&view=rev
Log:
Add a test for assignment operator behavior which was changed in
r195239, as well as a comment about the fact that assigning over
a moved-from object was in fact tested. Addresses some of the review
feedback on r195239.
