Jordan Rose	33438bd0f8	Add a test for circular protocol inheritance through a typealias ... We could do better on the diagnostics here, but it's not that important. https://bugs.swift.org/browse/SR-9224	2019-04-09 18:17:57 -07:00
Slava Pestov	8c653332ef	Sema: Fix failure to emit a diagnostic when a protocol witness is being validated already ... Validating a declaration can trigger conformance checking. If the conformance checker comes across the same declaration as a candidate witness, it would fail to emit a diagnostic. As a result we would then go onto SILGen, which would crash while emitting a witness table with a missing entry. Fixes <rdar://problem/45151902>.	2018-12-07 20:44:59 -05:00
