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`

slice_patterns: remove gates in tests 2019-12-30 00:23:42 +00:00			`#![allow(unused_variables)]`
Feature gate all slice patterns. #23121 Until some backwards-compatibility hazards are fixed in #23121, these need to be unstable. [breaking-change] 2015-03-27 01:34:27 +00:00
check-fast fallout from removing export, r=burningtree 2013-02-02 03:43:17 +00:00			`pub fn main() {`
Remove all `i` suffixes 2015-01-25 21:05:03 +00:00			`let x = &[1, 2, 3, 4, 5];`
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-26 00:06:52 +00:00			`let x: &[isize] = &[1, 2, 3, 4, 5];`
Add more tests 2012-12-15 23:13:55 +00:00			`if !x.is_empty() {`
			`let el = match x {`
Use new 'p @ ..' syntax in tests. 2019-07-07 23:47:46 +00:00			`&[1, ref tail @ ..] => &tail[0],`
Replace unreachable() calls with unreachable!(). This is the second of two parts of #8991, now possible as a new snapshot has been made. (The first part implemented the unreachable!() macro; it was #8992, 6b7b8f2682.) ``std::util::unreachable()`` is removed summarily; any code which used it should now use the ``unreachable!()`` macro. Closes #9312. Closes #8991. 2013-09-19 05:04:03 +00:00			`_ => unreachable!()`
Add more tests 2012-12-15 23:13:55 +00:00			`};`
Update the compiler to not use printf/printfln 2013-09-25 05:16:43 +00:00			`println!("{}", *el);`
