Some targets have a "far" address space that's bigger than the default.
rl78 for example has a 16-bit default pointer and a 32-bit far pointer.
Thanks for the pointer to an unusual target. I built cc1 for a
cross-compiler, and as far as I can see, the patch generates the same code
as before, both for regular and __far pointers, except in a few cases
where the patch simplifies more, but in a way that seems safe.
