[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
Add `#![allow(..)]` for a slew of lints of migrated run-pass tests, to silence stderr output. 2018-08-31 13:02:01 +00:00			`#![allow(non_camel_case_types)]`
Use `derive` rather than `deriving` in tests 2014-12-31 04:32:49 +00:00			`#[derive(PartialEq)]`
core: rename strbuf::StrBuf to string::String [breaking-change] 2014-05-22 23:57:53 +00:00			`enum t { a, b(String), }`
Isolate while-header bug to minimal testcase, fix in rustboot, remove workaround in rustc. 2010-11-19 22:59:58 +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 make(i: isize) -> t {`
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 08:05:53 +00:00			`if i > 10 { return t::a; }`
Replace usage of String::from_str with String:from 2015-06-08 14:55:35 +00:00			`let mut s = String::from("hello");`
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 18:19:50 +00:00			`// Ensure s is non-const.`

librustc: Remove the broken overloaded assign-ops from the language. They evaluated the receiver twice. They should be added back with `AddAssign`, `SubAssign`, etc., traits. 2013-06-12 02:13:42 +00:00			`s.push_str("there");`

check-fast fallout from removing export, r=burningtree 2013-02-02 03:43:17 +00:00			`pub fn main() {`
make --enforce-mut-vars always on, add mut annotations to remaining files 2012-03-22 15:39:41 +00:00			`let mut i = 0;`
