Subject: Flesh out the Objective-C section a bit. This may well need some love
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4d58212ab17801ba1dfef5f0a95a51d97c7701f0;p=clang

Flesh out the Objective-C section a bit. This may well need some love
from the Objective-C experts, but the basic stuff is there now.

+Clang 3.0 introduces several new Objective-C language features and improvements.

+<h4 id="objc_arc">Objective-C Automatic Reference Counting</h4>
+<!-- This is really just a stub for John to flesh out regarding ARC. -->
+ARC provides automated memory management for Objective-C programs that is
+compatible with existing retain/release code.  ARC is carefully built to
+be a reliable programming model that errs on the side of producing a
+compiler error instead of silently producing a runtime memory problem.
+ARC automates Objective-C objects, not malloc data, file descriptors,
+CoreFoundation datatypes or anything else. For more details, see the
+<a href="http://clang.llvm.org/docs/AutomaticReferenceCounting.html">full specification</a>.
+
+<h4 id="objc_instancetype">Objective-C Related Result Types / Instance
+Types</h4>
+Allows declaring new methods which follow the Cocoa conventions for methods
+such as <code>init</code> which always return objects that are an instance of
+the receiving class's type. For more details, see the
+<a href="http://clang.llvm.org/docs/LanguageExtensions.html#objc_instancetype">language extension documentation</a>.
