--- Comment #7 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I think it's safe to call this fixed. The remaining test cases are checked in.
I've linked bug 33301 to this because part of solving that one is likely the
same thing I mentioned here: we should bypass further transforms if we detect a
min/max because (as we can see there too), it's difficult to restore that
pattern.
