[llvm] r268409 -

[David Blaikie via llvm-commits]

Missing commit message? (could you provide it in a reply here - and try to
include commit messages in the commit in the future (ie: don't bother
reverting & recommitting this just to add a commit message unless you
particularly want to - some people might appreciate it when trawling
through the logs))
