Hi Jonas, I've regenerated the tests in https://reviews.llvm.org/rL325770 and the changes seem ok. The main difference I'm seeing is some moves are being eliminated, but in a few cases in test/CodeGen/Mips/analyzebranch.ll the earlier move prevents a delay slot being filled but otherwise looks ok.

https://reviews.llvm.org/differential/diff/135383 is my local copy of this patch against the regenerated tests.
