Devin Coughlin	1bf65c8c0d	[Analyzer] Fix crash in ObjCPropertyChecker on protocol property ... Fix a crash in the ObjCPropertyChecker when analyzing a 'copy' property of an NSMutable* type in a protocol. rdar://problem/30766684 Differential Revision: https://reviews.llvm.org/D30482 llvm-svn: 296562	2017-03-01 01:47:37 +00:00
Artem Dergachev	e69d2e47e5	[analyzer] Detect ObjC properties that are both (copy) and Mutable. ... When an Objective-C property has a (copy) attribute, the default setter for this property performs a -copy on the object assigned. Calling -copy on a mutable NS object such as NSMutableString etc. produces an immutable object, NSString in our example. Hence the getter becomes type-incorrect. rdar://problem/21022397 Differential Revision: https://reviews.llvm.org/D27535 llvm-svn: 289554	2016-12-13 17:19:18 +00:00
