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 07:18:55 -05:00			`// 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 16:51:35 -05:00			`#![allow(unused_macros)]`
Fix ICE with nested macros in certain situations. 2017-03-24 23:04:13 -05:00			`macro_rules! m {`
			`($e:expr) => {`
			`macro_rules! n { () => { $e } }`
			`}`
			`}`

			`fn main() {`
			`m!(foo!());`
			`}`
