Handle gateage of built-in attributes seperately This allows marking attributes as whitelisted/crate-only independent of their feature gate status. Closes #24213 2015-08-29 06:23:32 +08:00			`#![deny(unused_attributes)]`
			`#![feature(plugin)]`

Remove `Session.used_attrs` and move logic to `CheckAttrVisitor` Instead of updating global state to mark attributes as used, we now explicitly emit a warning when an attribute is used in an unsupported position. As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed. 2021-07-30 01:00:41 +08:00			`#[plugin(bla)] //~ ERROR should be an inner attribute`
