Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 14:18:55 +02:00			`// run-pass`
Add `#![allow(..)]` for a slew of lints of migrated run-pass tests, to silence stderr output. 2018-08-31 15:02:01 +02:00			`#![allow(deprecated)]`

Remove all unstable deprecated functionality This commit removes all unstable and deprecated functions in the standard library. A release was recently cut (1.3) which makes this a good time for some spring cleaning of the deprecated functions. 2015-08-11 17:27:05 -07:00			`use std::hash::{SipHasher, Hasher, Hash};`
