## Performance logs

> [triage logs 2024-06-13](https://github.com/rust-lang/rustc-perf/blob/master/triage/2024-06-11.md)

This week saw more regressions than wins, caused mostly by code being reorganized within the
compiler and a new feature being implemented. There have also been some nice improvements caused
by better optimizing spans.

Triage done by **@kobzol**.
Revision range: [1d52972d..b5b13568](https://perf.rust-lang.org/?start=1d52972dd8592edf4026aa577c8ce69acc0ac2d1&end=b5b13568fb5da4ac988bde370008d6134d3dfe6c&absolute=false&stat=instructions%3Au)

* Looks like it was caused by [#125968](https://github.com/rust-lang/rust/pull/125968).
* This PR resulted in some code being shuffled around the compiler (what we call "codegen noise"),
we determined that it is not worth investigating further.

Don't walk the bodies of free constants for reachability. [#122505](https://github.com/rust-lang/rust/pull/122505) [(Comparison Link)](https://perf.rust-lang.org/compare.html?start=72fdf913c53dd0e75313ba83e4aa80df3f6e2871&end=d0ccb5413ee2d9d40b574ad7998ffa866811d3f8&stat=instructions:u)

| All (primary) | 1.8% | [0.2%, 2.6%] | 4 |

* The compiler needs to do a little bit more work after this PR, so the regression is expected.

* Caused by [#125724](https://github.com/rust-lang/rust/pull/125724), which moves some code to
a different compiler package, so that it can be used with the new trait solver.
