[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +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 23:51:35 +02:00			`#![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. 2015-03-22 13:13:15 -07:00
Fix handling of ignored arguments in FFI wrappers for rust functions Fixes #16441. 2014-08-14 00:08:44 +02:00			`struct Empty;`

			`// This used to cause an ICE`
lints: add `improper_ctypes_definitions` This commit adds a new lint - `improper_ctypes_definitions` - which functions identically to `improper_ctypes`, but on `extern "C" fn` definitions (as opposed to `improper_ctypes`'s `extern "C" {}` declarations). Signed-off-by: David Wood <david@davidtw.co> 2020-05-28 15:57:09 +01:00			`#[allow(improper_ctypes_definitions)]`
