Rintaro Ishizaki	c138e4cd8f	[Sema] Swift3 compatibility: Fix ambiguous protocol composition production ... Fixes: https://bugs.swift.org/browse/SR-2843 'P1 & P2.Type' is mistakingly accepted and parsed as (meatatype (composition P1, P2)) in swift3. Now, we parse it as (composition P1, (metatype P2)) For source compatibility, reconstruct it as Swift3. Also, this solves inconsistent behavior between type and type-expression in Swift3. typealias T1 = P1 & P2? // was accepted as '(P1 & P2)?' let T2 = (P1 & P2?).self // was silently accepted as 'P1' in Swift3.0	2016-10-19 02:22:23 +09:00
Michael Ilseman	12fb0bad7b	[swift-version] Allow swift-version 4 and tests ... The recent @escaping on variadic argument closures back-compat fix is the first Swift 3.0 compatibility behavior that we don't want to carry forwards indefinitely into the future. To address this, we version-gate the diagnostic suppression. Makes it an official compatibility check. Creates new test directory for compatibility testing. Allow -swift-version 4 so that we can test it both ways.	2016-10-11 17:42:25 -07:00
