The title and description seems different than what we normally do. An example of such a commit is ab15016 Right now I am not sure what commit this will include from V8. |

The pull request should target the master branch or, if the slowdown does not affect V8 6.9, |

This applies a variant of v8/v8@e1163c14f7e4fef2c549 to V8 6.8. Original commit message: [Builtins] Array.prototype.forEach perf regression on dictionaries An unnecessary call to ToString() on the array index caused trips to the runtime. The fix also includes performance micro-benchmarks so we'll have a harder time regressing this case in future.

I’ve rebased against v10.x-staging, and update the commit message to point to v8/v8@e1163c1 (this is not a clean cherry-pick, though). CI: https://ci.nodejs.org/job/node-test-pull-request/17368/ |
