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 12:18:55 +00:00			`//@ run-pass`
Add `#![allow(stable_features)]` to ease review. That is, opting to ignore stable `#![feature(..)]`, under my theory that a reviewer would prefer as much stuff to be bucketed under "ah another `#![allow(..)]` here." as possible. 2018-08-31 13:58:57 +00:00			`#![allow(stable_features)]`

Fix ICE on using result of index on a constant to index into a constant The issue was that the const evaluator was returning an error because the feature flag const_indexing wasn't turned on. The error was then reported as a bug. Fixes #29914 2016-02-13 20:12:58 +00:00			`#![feature(const_indexing)]`
