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 `#![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
std: Clean out deprecated APIs Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma. 2016-03-07 15:42:29 -08:00			`mod u8 {`

rustc: Restrict the scope of a borrow on def_map This addresses the ICE from #13763, but it does not allow the test to compile, due to #13768. An alternate test was checked in in the meantime. Closes #13763 2014-04-25 14:42:36 -07:00
Remove unnecessary `as usize` 2015-03-28 16:07:25 +03:00			`const NUM: usize = u8::BITS;`

Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-25 17:06:52 -07:00			`struct MyStruct { nums: [usize; 8] }`

			`fn main() {`
Allow use of `[_ ; n]` syntax for fixed length and repeating arrays. This does NOT break any existing programs because the `[_, ..n]` syntax is also supported. 2014-12-20 15:20:51 +13:00			`let _s = MyStruct { nums: [0; NUM] };`
