What's your take on sdcc 6502 support at the moment, if you have one? Im just happy to finally have an 8-bit C compiler that supports both targets, even if the codegen for 6502 needs a lot of work right now. I'd happily take a llvm-z80 and llvm-6502 over sdcc if both were available Edit: oh wow, look at that https://github.com/grapereader/llvm-z80 https://github.com/grapereader/llvm-z80. Aw but not touched for 12 years.

Not the parent, but I have a take. :) For GBDK-2020 we've been using the 6502 support in SDCC to support the NES as a target console for about 2 years alongside the existing Game Boy and SMS/Game Gear targets. The 6502 port has been usable, but doesn't seem fully mature. There has been a lot of code churn for it during the last 12 months compared to the z80/sm83 ports as it gets improved. Recently (their recommended pre-release build 15614) this seems to have resulted in some breaking regressions that we haven't fully tracked down. Perhaps this port is getting less testing coverage than the z80/sm83 port. Unsure. The majority of the 6502 work seems to be done by a newer member of their team, with the longer term members seeming to be somewhat hands-off. That might be an additional factor. Edit: BTW, the 6502 port in SDCC at build 15267 (~4.5.0+) has been reasonably stable and usable, and is what we based our last GBDK-2020 release on (6 months ago).

  Ah thank you, that is all very helpful - I've been using 4.4.0 which is fine for Z80 code, but yeah had the feeling 6502 code generation could be improved.
