Use check-pass in ui tests where appropriate 2019-11-04 00:00:00 +00:00			`//@ check-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 23:51:35 +02:00			`#![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 13:13:15 -07:00			`//@ pretty-expanded FIXME #23616`

Tests for fixed issues. Closes #2074. Closes #5008. Closes #7519. Closes #7673. Closes #7770. Closes #8171. 2013-09-16 23:05:47 +10:00			`/*`

Fix run-pass tests to have 'pub fn main' This is required by the check-fast target because each test is slurped up into a submodule. 2013-09-25 00:43:37 -07:00			`pub fn main() {}`

Fallout: tests. As tests frequently elide things, lots of changes here. Some of this may have been poorly rebased, though I tried to be careful and preserve the spirit of the test. 2015-02-12 10:29:52 -05:00			`trait A {`

Update ui test suite to use dyn 2019-05-28 14:46:13 -04:00			`fn owned2<T: 'static>(a: Box<T>) { a as Box<dyn A>; }`
Remove even more box syntax uses from src/test Prior work, notably 6550021124451628b1efc60c59284465b109e3aa from #88316 has removed box syntax from most of the testsuite. However, some tests were left out. This commit removes box_syntax uses from more locations in src/test. Some tests that are very box syntax specific are not being migrated. 2022-07-07 04:36:10 +02:00			`fn owned3<T: 'static>(a: Box<T>) { Box::new(a) as Box<dyn A>; }`
