Yeah, I will add a ChangeLog entry for this patch when it is committed. I encountered the same issue when working on my local customized 4.8/4.9 branches. Not reproduceable with the official 4.8/4.9 branches. I thinks it's just an enhancement for the loop invariant pass to make it more versatile. It's better that 4.8/4.9 branches also inlcude this enhancement. OK?
