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 tests 2014-11-06 11:49:08 -05:00			`use std::default::Default;`

Use `derive` rather than `deriving` in tests 2014-12-31 17:32:49 +13:00			`#[derive(Default)]`
Add tests 2014-11-06 11:49:08 -05:00			`struct A {`
			`foo: Box<[bool]>,`
			`}`

			`pub fn main() {`
			`let a: A = Default::default();`
Switched to Box::new in many places. Many of the modifications putting in `Box::new` calls also include a pointer to Issue 22405, which tracks going back to `box <expr>` if possible in the future. (Still tried to use `Box<_>` where it sufficed; thus some tests still have `box_syntax` enabled, as they use a mix of `box` and `Box::new`.) Precursor for overloaded-`box` and placement-`in`; see Issue 22181. 2015-02-15 09:52:21 +01:00			`let b: Box<[_]> = Box::<[bool; 0]>::new([]);`
Add tests 2014-11-06 11:49:08 -05:00			`assert_eq!(a.foo, b);`
