'self.myIvar = nil' (properties) only releases myIvar when the property has kind 'assign'.  This fixes <rdar://problem/6380411>.

uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Issuing diagnostics when assigning to read-only properties.
This is work in progress.

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr

Distinguish between self.X = ... where self.X is a property reference and self.X is an implicit call to setX.

Fix PR 2978 false positive for missing release in -dealloc of an ivar retained via a property and then released by assigning nil to that property:

  http://llvm.org/bugs/show_bug.cgi?id=2978

llvm-svn: 58431

The attached patch adds additional checks to -warn-objc-missing-dealloc. It checks that all ivars which are used in implementation of synthesized properties are either

a) released in dealloc if the property has retain" or "copy" attribute OR
b) not released in dealloc if the property has "assign" attribute

Remove call to isSEL and isSEL itself since the call is dead (isObjCObjectPointerType() will never return true for selectors).

llvm-svn: 54034

Only warn about missing/incomplete -dealloc implementations when a class contains a non-SEL, non-IBOutlet ivar that references an ObjC object.

llvm-svn: 54024

Use ASTContext::isObjCObjectPointerType() to check if an ivar is a reference to an Objective-C object.

llvm-svn: 53647

Refactored error reporting in CheckObjCDealloc and CheckObjCInstMethSignature to use this new bug reporting interface (major code simplification).

This patch aims to address some of the concerns of PR 2517: http://llvm.org/bugs/show_bug.cgi?id=2517

For the -dealloc checker, check the LangOptions to determine whether or not the code is compiled with GC.

llvm-svn: 53098

Added static analysis check to see if a subclass of NSObject implements -dealloc, and whether or not that implementation calls [super dealloc].
