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(..)]` 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)]`
Further work on typestate_check Lots of work on typestate_check, seems to get a lot of the way through checking the standard library. * Added for, for_each, assign_op, bind, cast, put, check, break, and cont. (I'm not sure break and cont are actually handled correctly.) * Fixed side-effect bug in seq_preconds so that unioning the preconditions of a sequence of statements or expressions is handled correctly. * Pass poststate correctly through a stmt_decl. * Handle expr_ret and expr_fail properly (after execution of a ret or fail, everything is true -- this is needed to handle ifs and alts where one branch is a ret or fail) * Fixed bug in set_prestate_ann where a thing that needed to be mutated wasn't getting passed as an alias * Fixed bug in how expr_alt was treated (zero is not the identity for intersect, who knew, right?) * Update logging to reflect log_err vs. log * Fixed find_locals so as to return all local decls and exclude function arguments. * Make union_postconds work on an empty vector (needed to handle empty blocks correctly) * Added _vec.cat_options, which takes a list of option[T] to a list of T, ignoring any Nones * Added two test cases. 2011-04-20 19:11:01 +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 foo<T>(o: myoption<T>) -> isize {`
			`let mut x: isize = 5;`
Fix warnings it tests 2013-08-17 15:37:42 +00:00			`match o {`
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			`myoption::none::<T> => { }`
			`myoption::some::<T>(_t) => { x += 1; }`

Convert ret to return 2012-08-02 00:30:05 +00:00			`return x;`

rustc: Make the pretty printer output commas after enum variants. Update all tests accordingly. 2012-01-20 02:31:08 +00:00			`enum myoption<T> { none, some(T), }`
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 18:19:50 +00:00
Remove all `i` suffixes 2015-01-25 21:05:03 +00:00			`pub fn main() { println!("{}", 5); }`
