[PATCH] D81369: [Alignment][NFC] Migrate AtomicExpandPass to Align

[JF Bastien via Phabricator via llvm-commits]

jfb added a comment.

Would you update anything in the langref w.r.t. these two instructions? The RMW langref doesn't say anything, and the cmpxchg part says:

> The pointer passed into cmpxchg must have alignment greater than or equal to the size in memory of the operand.

You're preserving the natural alignment requirement in the code, but langref seems slightly imprecise.
