 Accurate Garbage Collection Intrinsics
 --------------------------------------

+LLVM's support for `Accurate Garbage Collection <GarbageCollection.html>`_
+(GC) requires the frontend to generate code containing appropriate intrinsic 
+calls and select an appropriate GC strategy which knows how to lower these 
+intrinsics in a manner which is appropriate for the target collector.

 These intrinsics allow identification of :ref:`GC roots on the
 stack <int_gcroot>`, as well as garbage collector implementations that
 require :ref:`read <int_gcread>` and :ref:`write <int_gcwrite>` barriers.

+Frontends for type-safe garbage collected languages should generate
 these intrinsics to make use of the LLVM garbage collectors. For more
