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`

remove the `float` type It is simply defined as `f64` across every platform right now. A use case hasn't been presented for a `float` type defined as the highest precision floating point type implemented in hardware on the platform. Performance-wise, using the smallest precision correct for the use case greatly saves on cache space and allows for fitting more numbers into SSE/AVX registers. If there was a use case, this could be implemented as simply a type alias or a struct thanks to `#[cfg(...)]`.

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 Point {`

Switch to purely namespaced enums This breaks code that referred to variant names in the same namespace as their enum.
