Wondering how different it is for these loop passes to be enabled for MonoLTO vs ThinLTO? If it's due to problems with the newPM, I guess ThinLTO would have the same problems? Asking because we have almost the same change as internal patch trying to get better LTO time profile precision for MonoLTO, and with that there's small win for oldPM+MonoLTO. But we'd love to converge on new PM for both MonoLTO and ThinLTO.
