Re-enable ThinLTO for rustc on `x86_64-apple-darwin` ThinLTO was disabled on x64 mac in https://github.com/rust-lang/rust/pull/105646 because of the https://github.com/rust-lang/rust/issues/105637 regression. It was later discovered that the issue was present on other targets as well, as the mac revert was already landing. The linux/win reverts, however, did not land before the root cause was identified. https://github.com/rust-lang/rust/pull/105800 fixed the underlying issue in `-Zdylib-lto` handling, and the x64 msvc and linux targets are now fixed, ICEs are using the correct `rustc_driver` panic hook. This PR re-enables ThinLTO on mac for improved perf now that the issue should be fixed everywhere. |
