The question is what ptrdiff_t is for a specific address space. Or

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.
Well, that's outside the scope of how TR 18037 defines the address space
feature, if ptrdiff_t is 16-bit. But it should still have nothing to do
with this patch as long as the patch keeps the result of the subtraction
having the same type it does at present.
Well, that's good then. Is the C front-end part of the patch ok for you?
