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
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 {`

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() {`
