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`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(dead_code)]`
type_of: use `sizing_type_of` to check the size of arrays when evaluating a recursive type, the type_of of the interior could be still in progress, so we can't use that. Fixes #19001 2015-10-27 21:02:23 +00:00			// check that we handle recursive arrays correctly in `type_of`

Make use of `ptr::null(_mut)` instead of casting zero 2019-06-17 10:52:37 +00:00			`let _t = Loopy { ptr: core::ptr::null_mut() };`
