Rintaro Ishizaki	c329d72cd7	[Sema] Fix a crash in use-before-declaration case (#18466) ... Check use-before-declaration early so we don't typecheck referenced decl which might depends on the reference. https://bugs.swift.org/browse/SR-7517 https://bugs.swift.org/browse/SR-8447 rdar://problem/39782719	2018-08-03 13:01:18 +09:00

Ding Ye	95b95e3d99	[Sema] Fix spurious use_local_before_declaration errors. ... When performing name lookup for UnresolvedDeclRefExpr, if a local declaration after use is detected, we check outer results to see if we can find better matching candidates before raising a use_local_before_declaration error. Resolves: SR-7660.	2018-06-03 19:59:45 +10:00
gregomni	e40038bdbd	It was possible to construct a series of declarations such that a variable was ... used before declared but the declaration was also marked invalid. This would end up diagnosing nothing and thus result in an obscure assert crash in SILGen instead. Solution is just to diagnose the use-before-declaration always.	2018-01-14 23:47:40 -08:00
