marcrasi	ce756e3189	[AutoDiff upstream] parsing for @differentiable function type (#27708) ... Adds parsing for a type attribute `@differentiable`, which is optionally allowed to have argument `@differentiable(linear)`. The typechecker currently rejects all uses of `@differentiable` with "error: attribute does not apply to type". Future work (https://bugs.swift.org/browse/TF-871 https://bugs.swift.org/browse/TF-873) will update the typechecker to allow this attribute in places where it is allowed. Resolves https://bugs.swift.org/browse/TF-822.	2019-11-04 23:40:04 -08:00
