Not sure why you conclude that code caching is going to benefit from this. Code caching really just helps you bypass compiling. What test results are you looking for?

I have two questions: 1. We knows JSC have 4 tiers, LLint => Baseline JIT ==> DFG ==> FLT, after v8 shipped new architecture, how many tiers does V8 have? 2. Whether the code cache of new architecture is byte code generated by Ignition? Albert.

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.
