Hi,

We already announced
<https://groups.google.com/d/msg/v8-dev/YXpjhVeHlbI/iiYlrF8vCgAJ> our plans
to switch on V8's new compiler architecture based on Ignition+TurboFan a
few weeks ago. This just happened (CL: V8 repo
<https://chromium.googlesource.com/v8/v8/+/0f716acadaed1d9e194593543dbe1340d600d6fc>
and Chromium repo
<https://chromium.googlesource.com/chromium/src/+/5e921f820bc0a86566e25b279019ba965535230e>
)!

This change is currently rolling into Chromium and running through
Chromium's whole test machinery. Rest assured that we already A/B-tested
the new pipeline extensively on Chromeperf, Clusterfuzz and Chrome
Canary/Dev. We don't anticipate regressions except on some traditional
synthetic JavaScript benchmarks like Octane.

Nevertheless, if you spot any regressions or failures please block this
rollout tracking bug
<https://bugs.chromium.org/p/chromium/issues/detail?id=698746>. We will
than work on resolving those blockers.

If you have questions, please do not hesitate to contact me.

Cheers,

Michael
