Douglas Gregor 1ac1b63c9c Implement variance for Objective-C type parameters. 
Introduce co- and contra-variance for Objective-C type parameters,
which allows us to express that (for example) an NSArray is covariant
in its type parameter. This means that NSArray<NSMutableString *> * is
a subtype of NSArray<NSString *> *, which is expected of the immutable
Foundation collections.

Type parameters can be annotated with __covariant or __contravariant
to make them co- or contra-variant, respectively. This feature can be
detected by __has_feature(objc_generics_variance). Implements
rdar://problem/20217490.

AnalysisBasedWarnings.cpp Switch users of the 'for (StmtRange range = stmt->children(); range; ++range)‘ pattern to range for loops. 2015-07-02 21:03:14 +00:00
AttributeList.cpp Automate attribute argument count semantic checking when there are variadic or optional arguments present. With this, the only time you should have to manually check attribute argument counts is when HasCustomParsing is set to true, or when you have variadic arguments that aren't really variadic (like ownership_holds and friends). 2014-07-31 16:37:04 +00:00
