[LLVMdev] MOS6502 target

[Edwin Amsler]

Oh yeah, I'm not expecting to port some major app. I have pretty intimate knowledge of what my c64 can and can't do. It barely has a kernel (pretty much just in-memory routines for disk, screen, and tape access).

This isn't a practical project (good C compilers exist already), this is an excuse to play with LLVM.
