Joe Groff	b7f84a68d7	Runtime: Allocate Swift errors as an NSError subclass. ... After some more discussion with John, we decided that subclassing is the only realistic option, at least until we eventually are able to integrate with the OS. Switch things around to allocate Swift error boxes as an ObjC subclass that contains the error value instead of trying to game it as a CFError. Swift SVN r26562	2015-03-25 23:02:57 +00:00
Joe Groff	668928cc83	Runtime: Handle ErrorType's layout in ExistentialTypeMetadata accessors. ... Teach ExistentialTypeMetadata how to project out the value pointer, type metadata, and protocol witness table from ErrorType containers. NFC yet; the dynamic casting and reflection machinery needs further work to correctly handle ErrorType boxes. Swift SVN r26509	2015-03-25 00:56:16 +00:00
