[Chandler Carruth via llvm-commits]

chandlerc added a comment.

This patch has no detailed descrpition. Can you add some context, such as problem trying to solve, link to discussions, and maybe why this approach is better than the other two proposed? (looking at the code now, but just wanted to make the initial comment)
