gregomni	d604047625	When root type of a keypath is unresolved by the constraint system, use the root interface type for diagnosis.	2018-07-31 17:15:12 -07:00
Mark Lacey	fea720f229	[MiscDiagnostics] Emit a deprecation warning for some writes through literal keypaths. ... We incorrectly allowed some keypaths to be inferred as writable keypaths in Swift 3/4 modes. This no longer happens when -swift-version 5 is specified. This warning is a limited attempt at providing some advanced notice of code that will break, only in the cases where the keypath is a direct argument to a keypath subscript write.

Mark Lacey	83ebd71644	Allowing forming WritableKeyPath to read-only value in Swift 3/4. ... We inadvertantly allowed this in the past, so continue to do so when compiling in Swift 3/4 mode to avoid suddenly breaking existing code. The diagnostic here is pretty bad, and I've opened issues for that as well as providing some kind of deprecation warning for this so that even under Swift 3/4 mode we alert users that this is unsupported. rdar://problem/39802797	2018-05-08 14:26:02 -07:00
