[PATCH] D39973: Fix CaptureTracking for llvm.invariant.group.barrier

[Piotr Padlewski via Phabricator via llvm-commits]

Prazek added a comment.

Firstly, are you sure that the invariant.group.barrier is the problem here? I didn't hear that it is used anywhere besides devirtualization, that is not turned on by default.
Here is my old path that was never reviewed:

As you can see, in order to check if the pointer passed to the barrier is captured, we need to check if all uses of the pointer returned by the barrier is not captured.
