I would like to port SDCC to target the V8 (AKA ArcLite) architecture.
The V8 is a very simple/regular Von Neumann architecture with 32 instructions,
an 8x8-bit register file and a 64Kbyte address space.
I have basic C skills, but I've never tackled anything like this
so any advice is appreciated.
I'd start by looking at the information in the manual 98.4 Retargetting for other Processors) and the links it points to.
