[PATCH] D71312: [InstCombine] Fold X / abs(X) to X < 0 ? -1 : 1

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Isn't it sufficient to just check that the true/false values of the select are x and -x. The condition itself doesn't matter.   x / (select c, x, -x) ->  select c ? 1 : -1
