[PATCH] D109548: Make llvm.launder.invariant.group writeonly

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Generally though, I think we should consider adding a new attribute to mark intrinsics like this, rather than using inaccessiblememonly. Ideally we don't want to mix these up with memory effects, and just want to say "don't remove or CSE this intrinsic" ("do not hoist" is already implied by lack of speculatable).
