Doug Gregor	e1545a7d5a	[Type checker/runtime] Move default implementation of Error._code into the runtime. ... Rather than having Sema provide a default implementation of Error._code when needed, introduce a runtime function to extract the default code, so that we can provide a default implementation via a protocol extension in the standard library.	2016-08-25 16:00:19 -07:00
Doug Gregor	6d2f11a305	[Type checker] Synthesize Error._code witnesses as 'final' within a class. ... When synthesizing the witness for Error._code, synthesize it as final. This isn't meant to be user-visible (and, therefore, isn't meant to be user-overridable), so it's a minor efficiency win. Moreover, we weren't making sure this member got synthesized in in cross-module situations, leading to runtime crashes. Fixes rdar://problem/27335637.	2016-08-01 21:27:51 -07:00
