[swift-dev] [Swift CI] Build Failure: 0. OSS - Swift Incremental RA - OS X (master) #3504

[Greg Parker]

Looks like it was caused by the RR code motion merge (https://github.com/apple/swift/pull/2064). 

Xin, I'm planning to revert 49f1c66d7b20b29097d7aec99835c5a42a2048bf and 3824a9479ed2df701dffff4a0c9467495a4c37f0 once my tests finish, unless you have a fix in the next few minutes.
