I've opened a feature request for the ez80 backend (https://sourceforge.net/p/sdcc/feature-requests/582/) and would be willing to implement it on the compiler side for SDCC 3.9.0. But we'd also need support in the assembler. And to make it a "stable" (as opposed to "in development") backend, it would have to pass regression tests, for which we'd need an emulator (having an ucsim one would be best, as those are already used for most backends, and the upstream developer works closely with SDCC developers). Since the eZ80 is quite similar to the Z180 (whcih is already supported by ucsim), the easiest is probably to just make an ucsim-based one. Philipp
