This may be an older failure recently uncovered by changes to which tests get run. Jordan, Erik, any guesses of changes that might have broken it?

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.

Disabling the pass that way may have caused two more SILOptimizer test failures:
https://ci.swift.org/job/oss-swift-incremental-RA-linux-ubuntu-15_10/4351/

I also suspect that the ArrayTraps failure is caused by something in the RR motion branch, but I'm still working to confirm that.

To summarize. I think I fixed the non-determinism in commit 7d26a472009eae673fd40a0403ceb319027481be and re-enabled retain release code motion (RRCM).

I do not think the array test failure is related to RRCM , the benchmark failed even after i disabled RRCM.

I meant if you look into the console output, the array test is still failing with RRcodemotion disabled.

Looks good. Thanks.

I agree about the array failure. I mistakenly considered an OS X test in that diagnosis, but the test isn't failing anywhere on OS X.
