If ever a GCC port is produced, I think it would be fun to port the RTEMS RTOS.  Not only is easy to port, but it can operate using cooperative multithreading, and is embedded in real space missions today. And, FWIW, I've seen full GNU tools ports to targets with less memory! [thanks for proof reading - edits made]

With that out of the way, thank you for writing this insightful article.  There are some significant issues with writing a C compiler for DCPU-16, so we (the community) may have to come up with a different, very C-like language and port GNU to it.  And then there's the question of GNU's usability in a 128KB machine.  Time will tell, I suppose.

When you have delay slots, you're letting an internal revision-specific detail leak out into the ABI, forever forcing you to emulate the behavior of the original core.
