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.
