[PATCH] D45320: [MemDep] Fixed handling of invariant.group

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

"I know, I also wish we would get rid of MemDep asap, but as long as it's there, it would be good to avoid weird miscompilations that causes calls to vtable."

But it still will, just not in this particular way. 
But it will still fail in very common ways anyway :)

We may actually have to disable preservation entirely for the moment anyway.
