// This test is checking that usage of an existential (which is normally
|
|
// disallowed in embedded Swift and flagged in IRGen) is left undiagnosed
|
|
// because the context is @_unavailableInEmbedded.
|
|
//
|
|
// The breakdown of that is
|
|
// - (1) @_unavailableInEmbedded makes the declaration unavailable,
|
|
// - (2) unavailable function bodies is removed in embedded Swift,
|
|
// - (3) the test() function is not reported by the existential checker.
