+<p>The <a href="#llvm_eh_sjlj_longjmp"><tt>llvm.eh.sjlj.longjmp</tt></a>
+   intrinsic is used to implement <tt>__builtin_longjmp()</tt> for SJLJ
+   style exception handling. The single parameter is a pointer to a
+   buffer populated by <a href="#llvm_eh_sjlj_setjmp">
+     <tt>llvm.eh.sjlj.setjmp</tt></a>. The frame pointer and stack pointer
+   are restored from the buffer, then control is transfered to the
+   destination address.</p>
