function. This value can be used to compare against the result of
``landingpad`` instruction. The single argument is a reference to a type info.
+Uses of this intrinsic are generated by the C++ front-end.

+SJLJ Intrinsics
+---------------
+
+The ``llvm.eh.sjlj`` intrinsics are used internally within LLVM's
+backend. Uses of them are generated by the backend's
+``SjLjEHPrepare`` pass.
