Re: [sdcc-devel] Having __far pointers that are wider than generic pointers?

[Philipp K. K. <pk...@sp...>]

Another use-case for pointers not part of the generic address space
would be pointers to __sfr.

For some architectures (mcs51, pdk), the hardware doesn't have good
support for pointers to __sfr, so no point implementing them.

For some (stm8, f8, sm83), __sfr is a susbet of the generic space.

For others (z80-related excpet sm83), __sfr is not part of the generic
address space. Here it would make sense to allow pointers to __sfr
without having to make the generic pointers wider.

P.S.: __sfr is a rather mcs51-centric name. Maybe __io would be a good
alternative spelling of the keyword?
