Remove `feature` from the list of well known check-cfg name This PR removes `feature` from the list of well known check-cfg. This is done for multiple reasons: - Cargo is the source of truth, rustc shouldn't have any knowledge of it - It creates a conflict between Cargo and rustc when there are no features defined. In this case Cargo won't pass any `--check-cfg` for `feature` since no feature will ever be passed, but rustc by having in it's list adds a implicit `cfg(feature, values(any()))` which is completely wrong. Having any cfg `feature` is unexpected not allow any `feature` value. While doing this, I took the opportunity to specialise the diagnostic a bit for the case above. r? `@petrochenkov` |
