Use build-pass in ui tests where appropriate 2019-10-29 00:00:00 +00:00			`// build-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(dead_code)]`
Consistently normalize fn types after erasing lifetimes. Fixes #23406. Fixes #23958. Fixes #29832. 2015-11-14 20:12:12 +00:00			`trait Inner {`
