SDCC Compiler port to V8/ArcLite

I am interested in modifying the open source SDCC C compiler to
generate code for the V8 target architecture.  The V8 (AKA ArcLite) 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 or of anyone wants to collaborate on this that would be
great.

Thanks,
Scott
