[PATCH] D108992: [KnownBits] Add support for X+X and X*X self-addition/multiplication

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Though InstCombine already canonicalizes `add x, x` to `shl x, 1`, so it probably doesn't make sense to explicitly handle that case at all.
