Accurate Garbage Collection Intrinsics
--------------------------------------
LLVM support for `Accurate Garbage Collection <GarbageCollection.html>`_
(GC) requires the implementation and generation of these 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.
Front-ends for type-safe garbage collected languages should generate
Frontends for type-safe garbage collected languages should generate
these intrinsics to make use of the LLVM garbage collectors. For more
details, see `Garbage Collection with LLVM <GarbageCollection.html>`_.
