add rustc_private as a proper language feature gate At the moment, `rustc_private` as a (library) feature exists by accident: `char::is_xid_start`, `char::is_xid_continue` methods in libcore define it. 2019-07-22 12:09:34 +03:00			`// gate-test-rustc_private`

use backticks instead of single quotes when reporting "use of unstable library feature" This is consistent with all other diagnostics I could find containing features and enables the use of `DiagSymbolList` for generalizing diagnostics for unstable library features to multiple features. 2024-11-02 16:10:24 -07:00			extern crate cfg_if; //~ ERROR use of unstable library feature `rustc_private`
