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`

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`

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			`fn uint_to_foo(_: usize) -> Foo {`

Remove integer suffixes where the types in compiled code are identical. 2015-03-03 10:42:26 +02:00			`(0..10).map(uint_to_foo);`
