A couple of things that come to mind:
1. Code generation would need to take into consideration the way OS-9
spawns processes and hands them memory (U points to the process's data
area, DP to the beginning of the data area, if memory serves). cstart
would need to know about parameters and environment variable passage.
2. Code generation would have to be position-independent.
