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 reverse(v: &mut [usize]) {`
Convert vec::{reverse, swap} to methods. 2013-06-28 16:54:03 +00:00			`v.reverse();`
Rewrite the coercion code to be more readable, more sound, and to reborrow when needed. Regarding soundness: there was a subtle bug in how it was done before; see the compile-fail test for an example. Regarding reborrowing: reborrowing allows mut and const slices/borrowed-pointers to be used with pure fns that expect immutable data. r=brson 2013-01-23 01:20:08 +00:00			`}`

check-fast fallout from removing export, r=burningtree 2013-02-02 03:43:17 +00:00			`pub fn main() {`
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 mut the_vec = vec![1, 2, 3, 100];`
cleanup: replace `as[_mut]_slice()` calls with deref coercions 2015-02-02 02:53:25 +00:00			`bar(&mut the_vec);`
Use arrays instead of vectors in tests 2015-02-24 18:15:45 +00:00			`assert_eq!(the_vec, [100, 3, 2, 1]);`
