Use check-pass in ui tests where appropriate 2019-11-04 00:00:00 +00:00			`//@ check-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)]`
Refactor representation of bounds to separate out BuiltinBounds into its own type. Use a bitset to represent built-in bounds. There are several places in the language where only builtin bounds (aka kinds) will be accepted, e.g. on closures, destructor type parameters perhaps, and on trait types. 2013-05-07 21:30:21 +00:00			`// Tests that impls are allowed to have looser, more permissive bounds`

Don't check impl ty params for equality with trait ty params This was too restrictive. We need to check the number of ty params, and that the bounds are equal, but otherwise require_same_types does the job. Closes #2611 2012-09-05 22:36:11 +00:00
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

Fallout: tests. As tests frequently elide things, lots of changes here. Some of this may have been poorly rebased, though I tried to be careful and preserve the spirit of the test. 2015-02-12 15:29:52 +00:00			`fn b<C:Sync,D>(&self, x: C) -> C;`

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			`f: isize`

Fix run-pass tests to have 'pub fn main' This is required by the check-fast target because each test is slurped up into a submodule. 2013-09-25 07:43:37 +00:00			`pub fn main() {}`
