 ### Rust Compiler Performance Triage
 
-<!-- Perf results go here -->
+Relatively quiet week, with one large-ish regression that will be reverted.
+[#132666](https://github.com/rust-lang/rust/pull/132666) produced a nice perf. win, by skipping
+unnecessary work. This PR actually reversed a regression caused by a [previous PR](https://github.com/rust-lang/rust/pull/131984).
+
+Triage done by **@kobzol**.
+
+Revision range: [9a1d156f..f7538506](https://perf.rust-lang.org/?start=9a1d156f38c51441ee51e5a068f1d0caf4bb0f27&end=f753850659bdf5788332525f3fe395685929c682&absolute=false&stat=instructions%3Au)
