[PATCH] D117926: [SLP] Optionally preserve MemorySSA

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Can you please explain what the larger context here is? What cases you trying to solve with MemorySSA?

I'm not sure it will be the right tool for the job, so I think we should discuss this before making any changes. We don't have MSSA available at SLP's pipeline position, and computing it just for SLP will make this pass much more expensive.
