Guillaume Gomez b0ae228007 Rollup merge of #141413 - est31:cfg_version_env_var, r=jieyouxu ... Make #[cfg(version)] respect RUSTC_OVERRIDE_VERSION_STRING The `#[cfg(version(...))]` feature is currently under-tested. Part of it is the difficulty that it is hard to write a test that never changes, while the version of the Rust compiler indeed *does* change. PR #81468 added the first and so far only test of `#[cfg(version(...))]`'s functionality (there is one other test for the *syntax*, that also acts as feature gate). But that test uses a proc macro that parses the version: the text of the test doesn't contain the actual `#[cfg(version(...))]`. This PR makes `#[cfg(version(...))]` respect `RUSTC_OVERRIDE_VERSION_STRING`, added by PR #124339, allowing us to virtually pin the rustc version and write tests from all directions against some specific version. The PR also adds a functional test of `#[cfg(version(...))]` that leverages `RUSTC_OVERRIDE_VERSION_STRING`. Pulled out of #141137. Tracking issue: #64796		2025-05-25 15:11:47 +02:00
