* Weaken the ObjCSelfInitChecker to only warn when one calls an 'init' method ↵Ted Kremenek2011-02-121-7/+22

* [analyzer] Fix a false positive of the 'self' initialization checker.Argyrios Kyrtzidis2011-02-051-4/+20
| | | | | | | | | | | | | | | | | | | A common pattern in classes with multiple initializers is to put the subclass's common initialization bits into a static function that receives the value of 'self', e.g: if (!(self = [super init])) return nil; if (!(self = _commonInit(self))) return nil; It was reported that 'self' was not set to the result of [super init]. Until we can use inter-procedural analysis, in such a call, transfer the ObjCSelfInitChecker flags associated with 'self' to the result of the call. Fixes rdar://8937441 & http://llvm.org/PR9094 llvm-svn: 124940
