Can you explain the fix? |

Many layers of different overloads combined with fast and slow paths makes this code pretty sensitive. I hope we will get a chance to simplify this in future (#16434 has some good changes that are going in the right direction, I think). |

Before this change, the two argument method on the rare path got inlined and made the prolog of this method larger and in turn regressed the method for the case of two identical strings. After this change, the six argument method on the rare path is not getting inlined and so it maintains the performance characteristics that it used to have. (The change is a one liner revert of changes made in #17237.) |
