Could you clarify?
This only works when you add support for the different pointer modes. I was saying the middle support for this feature was already there, just the target support was not. Also there are issues with mode on pointers for C++, I don't know what they are though. Note this feature is used on the s390 target and also the ia64-hpux targets. --Pinski
