Can freepascal be used on small processors that are 8 or 16 bits or does it expect that there are at least 32 bits for most things? I've been tempted lately to start making little circuits with microcontrollers on them. I realize that a great deal of the rtl/fcl would not be used on these little processors. Also since there is no OS on these devices does that mean that for sure fpc cannot work?
Most of the RTl is written for 32- and 64-bit computing, as you correctly state. I would imagine that _some_ of it would work on 16-bit, and maybe 1-2% would work on 8-bit ;-)
However, you can choose to compile fpc without the system unit, using a special option on the command-line. This would enable you to code your own system routines (such as writeln), most likely in assembler.
However, the most obvious problem here is that (AFAIK) fpc does not support arbitrary 8- and 16-bit targets. You need to find an architecture that fpc supports, so you can compile programs for it.
Other people on this list probably know more about embedded systems than I do, so I hope someone else can answer with the specifics.
