Thanks for working on this. This pattern is also seen in spec2006/mcf, I will test this patch on AArch64/Kryo and let you know the results. FWIW, I think this is always good when the Loop has a single latch only, but for loops with multiple latches it might not always be beneficial without knowing the actual branch probabilities.
