[PATCH] D59071: [Transform] Improve saddo with mixed signs

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

D59386 <https://reviews.llvm.org/D59386> implements the full optimization for the unsigned case, and D59450 <https://reviews.llvm.org/D59450> is preparation for the signed add case, though there's a few more followups necessary there (for signed sub, for extension to use computeConstantRange, and for handling AlwaysOverflows).
