+--stitch-lbr::
+       Show callgraph with stitched LBRs, which may have more complete
+       callgraph. The perf.data file must have been obtained using
+       perf record --call-graph lbr.
+       Disabled by default. In common cases with call stack overflows,
+       it can recreate better call stacks than the default lbr call stack
+       output. But this approach is not full proof. There can be cases
+       where it creates incorrect call stacks from incorrect matches.
+       The known limitations include exception handing such as
+       setjmp/longjmp will have calls/returns not match.
