It's certainly doable, but generally on an 8-bit microprocessor code size is paramount. gcc's optimizations are tuned better for performance than for code size. Also, code code on 8-bit microprocessors can require optimizations which gcc is particularly weak at, such as good use of auto-increment, and coalescing register offsets. If you are not an experienced gcc developer, actually doing the port is a fairly difficult task. The documentation for doing a new port is reasonably good but it does not tell you everything you need to know. It is available online at http://gcc.gnu.org/onlinedocs/gccint/ . There are professional companies and individuals you can hire to do a gcc port. If this is for a commercial project it will generally be more cost-effective to hire an expert to do the work. Ian
