Saleem Abdulrasool	bc27395838	Inputs: sprinkle _Null_unspecified to silence nullability-completness ... When trying to figure out errors from an import failure, the nullability completeness warnings would clutter the output making it difficult to identify the errors. Sprinkle the declaarations with `_Null_unspecified` to maintain the current nullability semantics and silence the warnings. NFC.	2018-06-11 09:23:22 -07:00
Joe Groff	f9c267c9ef	SILGen: Accept optionals as ABI-compatible in either direction as block arguments. ... The thunking code we have for introducing runtime nil checks in thunks when an optional-to-non conversion appears in contravariant position doesn't handle blocks. This somehow-worked in previous versions of Swift (maybe due to assertions being off). Spot fix for rdar://problem/36843476.	2018-01-26 14:37:40 -08:00
