[PATCH] D152876: [InstCombine] Expand `foldBinOpShiftWithShift` to handle multiple binops

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Is it possible to handle just the case `binop(optional_binop1(shift), optional_binop2(shift))`? I believe that's all that is necessary for the motivating cases and should allow a much cleaner implementation.
