[Dwarf-Discuss] FDEs involving predicated instructions

I'm wondering the best way to handle predicated prolog/epilog instructions in the Call Frame Information.

Suppose you have an epilog instruction that restores an SOE register and it is predicated and scheduled in a predecessor block.  How do you handle emitting an FDE rule that describes that a register is restored when a predicate or status register is a certain value?

I can give an example if this isn't clear.

Thanks!
