Alex Crichton d7d7045374 rustc: Allow #[no_mangle] anywhere in a crate ... This commit updates the compiler to allow the `#[no_mangle]` (and `#[export_name]` attributes) to be located anywhere within a crate. These attributes are unconditionally processed, causing the compiler to always generate an exported symbol with the appropriate name. After some discussion on #54135 it was found that not a great reason this hasn't been allowed already, and it seems to match the behavior that many expect! Previously the compiler would only export a `#[no_mangle]` symbol if it were *publicly reachable*, meaning that it itself is `pub` and it's otherwise publicly reachable from the root of the crate. This new definition is that `#[no_mangle]` *is always reachable*, no matter where it is in a crate or whether it has `pub` or not. This should make it much easier to declare an exported symbol with a known and unique name, even when it's an internal implementation detail of the crate itself. Note that these symbols will persist beyond LTO as well, always making their way to the linker. Along the way this commit removes the `private_no_mangle_functions` lint (also for statics) as there's no longer any need to lint these situations. Furthermore a good number of tests were updated now that symbol visibility has been changed. Closes #54135		2018-10-06 13:57:30 -07:00
