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 07:18:55 -05:00			`// 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 16:51:35 -05:00			`#![allow(dead_code)]`
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 15:13:15 -05:00			`// 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 19:06:52 -05:00			`fn sum(x: &[isize]) -> isize {`
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 2013-01-22 19:20:08 -06:00			`let mut sum = 0;`
