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`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(dead_code)]`
Add `#[allow(improper_ctypes)]` to slew of cases that need e.g. `repr(C)`. See also rust-lang/rust#53858. 2018-08-31 13:51:35 +00:00			`#![allow(improper_ctypes)]`

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			`//@ pretty-expanded FIXME #23616`
Require feature attributes, and add them where necessary 2015-03-06 02:33:58 +00:00

librustc: Forbid private types in public APIs. This breaks code like: struct Foo { ... } pub fn make_foo() -> Foo { ... } Change this code to: pub struct Foo { // note `pub` ... } pub fn make_foo() -> Foo { ... } The `visible_private_types` lint has been removed, since it is now an error to attempt to expose a private type in a public API. In its place a `#[feature(visible_private_types)]` gate has been added. Closes #16463. RFC #48. [breaking-change] 2014-09-19 19:30:07 +00:00			`pub struct KEYGEN {`
Allow use of `[_ ; n]` syntax for fixed length and repeating arrays. This does NOT break any existing programs because the `[_, ..n]` syntax is also supported. 2014-12-20 02:20:51 +00:00			`hash_algorithm: [c_uint; 2],`
