<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>
