I am concerned about this behaviour. I understand that mixing
synthetic CFI statements and real ones would be a bad idea, but
I think that silently ignoring the real ones is a mistake. At
the very least you ought to generate a warning message letting
the user know that their cfi instructions are being ignored.
Cheers
Nick
