Per the release note, upstream is now building their dist binary with codegen-units = 1 in [rust] section. It makes the produced compiler binary and "std" library 1.5% faster, and IMO we'd do the same.

And upstream has enabled lto = "thin" for dist build in the [rust] section since 1.66.0. It would make the compiler 4% faster.

I get some "unexpected" thing running test with rust.lto=thin. I've created ​https://github.com/rust-lang/rust/pull/119414 waiting for a review.

The tests ui/issues/issue-21763.rs and debuginfo/regression-bad-location-list-67992.rs still fail. No new failure observed.

I've got an approve so I'll add it as a patch.

Sounds good! Was that the last piece for this update?

The last piece is thunderbird. The build is still running (though it seems all Rust code has been already successfully compiled).
