You shouldn't if everything else is working right.  But, from what's been
reported here, you do, so it seems that something is broken.

As I said, it may well be that we already don't need libcall notes anymore
if some small bugs are fixed and it may well be better to fix those bugs
and kill the concept than to do further work on it.
