[PATCH] D99599: [NewPM] Add an option to dump pass structure

[Petr Hosek via Phabricator via cfe-commits]

phosek added a comment.

It looks like the `BarrierNoop` pass is inserted under `-O0` when any extension is registered <https://github.com/llvm/llvm-project/blob/749702fc6ba268cb0096c09393db51a20bb5eb0d/llvm/lib/Transforms/IPO/PassManagerBuilder.cpp#L558>. We enable Polly in our toolchain so that's likely the reason why we're seeing this on our bots.
