Allan Shortlidge	0ac8cd35d2	Sema: Allow resilient modules to add enum elements without breaking clients. ... In the implementation of https://github.com/swiftlang/swift/pull/73472, warnings about uncovered cases were upgraded to errors in switches covering enums with an `@unknown default` case. This change was a mistake; it should not be source breaking for a resilient library to add new cases to a non-frozen enum. Resolves rdar://138488976.	2024-10-23 12:41:31 -07:00

Robert Widmann	2fb5afb755	Remove the @_downgrade_exhaustivity_check hack ... This hack was only needed for Swift 3 mode in a narrow case. Flush it out of the compiler so we can simplify the space engine.	2018-08-24 10:54:43 -07:00
Jordan Rose	ceb51eea80	Clean up fix-it generation for missing cases, esp. with '@unknown' ... - Combine the common logic for editor mode and non-editor mode. - Do a better job minimizing fix-its. - If '@unknown' is the only missing case, put `fatalError()` in the Xcode placeholder, since that's what the compiler would have done.	2018-04-05 16:35:15 -07:00
