commit 9827440f1e723423baf4c235e844eb8ac48a8f97 Author: Peng Liu <winner245@hotmail.com> Date: Wed Jun 18 12:22:47 2025 -0400 [libc++] Optimize ranges::{for_each, for_each_n} for segmented iterators (#132896) Previously, the segmented iterator optimization was limited to `std::{for_each, for_each_n}`. This patch extends the optimization to `std::ranges::for_each` and `std::ranges::for_each_n`, ensuring consistent optimizations across these algorithms. This patch first generalizes the `std` algorithms by introducing a `Projection` parameter, which is set to `__identity` for the `std` algorithms. Then we let the `ranges` algorithms to directly call their `std` counterparts with a general `__proj` argument. Benchmarks demonstrate performance improvements of up to 21.4x for ``std::deque::iterator`` and 22.3x for ``join_view`` of ``vector<vector<char>>``. Addresses a subtask of #102817. |
