Hi Evgeny, please let me know if you need some more deep explanation about workaround Sanjoy and I mentioned in terms of stripping nuw/nsw for instruction in case you are in LSR.
This is for the case: the regressions are urgent for you and you need some quick workaround while you are investigating why SCEV lost the poison flags.
