This can have very large impacts on benchmarks where linking dominates the build time (e.g., `ripgrep`, `exa`, small binaries like `hello-world`). Aside from that change, there were a few small regressions that were either deemed worth it or are still being investigated. + +Triage done by **@rylev**. +Revision range: [9105c57b..1d0e4afd](https://perf.rust-lang.org/?start=9105c57b7f6623310e33f3ee7e48a3114e5190a7&end=1d0e4afd4cac09078e12a232508c3e9f8d42535d&absolute=false&stat=instructions%3Au) + +**Summary**: + +| (instructions:u) | mean | range | count | +|:----------------------------------:|:------:|:---------------:|:-----:| +| Regressions ❌
