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`
test: Make manual changes to deal with the fallout from removal of `~[T]` in test, libgetopts, compiletest, librustdoc, and libnum. 2014-03-05 23:28:08 +00:00
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 20:13:15 +00:00
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-26 00:06:52 +00:00			`fn swap<F>(f: F) -> Vec<isize> where F: FnOnce(Vec<isize>) -> Vec<isize> {`
Changed most vec! invocations to use square braces Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets. 2016-10-29 21:54:04 +00:00			`let x = vec![1, 2, 3];`

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 07:43:37 +00:00			`pub fn main() {`

test: Remove non-procedure uses of `do` from compiletest, libstd tests, compile-fail tests, run-fail tests, and run-pass tests. 2013-11-22 01:23:21 +00:00			`let w = swap(\|mut x\| { x.push(4); x });`
