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(..)]` 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)]`
rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 20:13:15 +00:00			`//@ pretty-expanded FIXME #23616`

Make RFC 1214 warnings into errors, and rip out the "warn or err" associated machinery. Future such attempts should go through lints anyhow. There is a fair amount of fallout in the compile-fail tests, as WF checking now occurs earlier in the process. 2015-12-15 09:31:58 +00:00			`pub trait NumCast: Sized {`
