[PATCH] D50167: RFC: [SCEV] Add explicit representations of umin/smin

[Keno Fischer via Phabricator via llvm-commits]

loladiro updated this revision to Diff 159239.
loladiro added a comment.

Fix a small bug discovered during production testing (
when expanding umin/umax, don't go to integers just because
types are unequal - the only reason to do is if one of the
operands in an integer and the other is not).
