I managed to break this in https://github.com/rust-lang/rust/pull/95449. I am not quite sure why this is the correct fix, but it doesn't break `doc --stage 0` and is strictly closer to the previous behavior. Previously, rustdoc would error with strange issues because of the mismatched sysroot: ``` error[E0460]: found possibly newer version of crate `std` which `rustc_span` depends on --> /home/jnelson/rust-lang/rust/compiler/rustc_lint_defs/src/lib.rs:14:5 | 14 | use rustc_span::{sym, symbol::Ident, Span, Symbol}; | ^^^^^^^^^^ | = note: perhaps that crate needs to be recompiled? = note: the following crate versions were found: crate `std`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd-ff9290e971253a38.rlib crate `std`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd-ff9290e971253a38.so crate `rustc_span`: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0-rustc/x86_64-unknown-linux-gnu/release/deps/librustc_span-ed11dce30c1766f9.rlib ``` |
