Would you be interested in seeing support for some so-called undocumented Z80 instructions in sdcc? This would be available via a command-line switch, that would allow sdcc to generate the following:
adc a, ir add a, ir and a, ir cp a, ir inc ir ld ir, ir' ld ir, n ld ir, r ld r, ir or a, ir sbc a, ir sub a, ir xor a, ir Where ir/ir' is iyh or iyl, and r is a, b, c, d or e, and n is an 8-bit immediate. For targets that support them this could result in slightly smaller and faster code since it allows more flexible use of iy. AFAIK most softcore implementation of the Z80 officially support them, and they just work on most other implementations as well, even where this is not documented.
