That's very interesting, because I'd like to know if the GCC maintainers are interested in the changes I would have to make to GCC for it to support the different PDP-10 pointer formats. It's my intention that the changes should be as non-intrusive as possible and make GCC easier to port to other architectures with unsusual pointer formats. My employer may be willing to sponsor this if it's an improvement of GCC. But if the GCC maintainers are not interested in this, I'd rather just make the changes necessary for PDP-10 without considering other architectures. The same goes for binutils and GDB, by the way. I certainly don't expect the maintainers to actively maintain the PDP-10 back end, or even care much if it breaks.
