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 20:18:55 +08:00			`// run-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-26 05:51:35 +08:00			`#![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. 2015-03-23 04:13:15 +08:00
Fix #14865 Fixes a codegen bug which generates illegal non-terminated LLVM block when there are wildcard pattern with guard and enum patterns in a match expression. Also refactors the code a little. Closes #14865 2014-06-18 22:33:58 +08:00			`enum X {`
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-26 08:06:52 +08:00			`Foo(usize),`

Switch to purely namespaced enums This breaks code that referred to variant names in the same namespace as their enum. Reexport the variants in the old location or alter code to refer to the new locations: ``` pub enum Foo { A, B } fn main() { let a = A; } ``` => ``` pub use self::Foo::{A, B}; pub enum Foo { A, B } fn main() { let a = A; } ``` or ``` pub enum Foo { A, B } fn main() { let a = Foo::A; } ``` [breaking-change] 2014-11-06 16:05:53 +08:00			`let x = match X::Foo(42) {`
Remove all `i` suffixes 2015-01-26 05:05:03 +08:00			`X::Foo(..) => 1,`
