I recently used some version of SDCC as a part of the old GBDK. It did produce working binaries, but only after some significant coaxing to avoid internal compiler errors. It might be attributable to GBDK's old SDCC fork, but it really wasn't a pleasant experience and took a lot of guesswork to get things working (separate code into two functions? ICE! reorder two variable names? ICE! nested conditionals? ICE!)
