[PATCH] D146928: [NaryReassociate] Transform expression (X << C1) + C2 to (X + C3) << C1,

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

Do you know why at all InstCombine would want to transform `(X + const1) << 22` into `(X << 22 + const2)`? By itself it doesn't seem profitable. Does it enable any useful further transforms?
