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 14:18:55 +02:00			`//@ run-pass`
tests: use `needs-threads` instead of `ignore-emscripten` 2025-01-23 17:05:01 +08:00			`//@ needs-threads`
Ignore an i128 test on emscripten 2018-01-25 21:04:01 -08:00
rustc_trans: take into account primitives larger than 8 bytes. 2018-01-15 01:18:48 +02:00			`#[repr(C)]`
			`pub struct Foo(i128);`

			`#[no_mangle]`
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).
