> cram anything into a 6502
I noticed some people working on an LLVM backend for the 6502; I may revisit the C-64 target once that matures (it will generate better code than cc65, and I'm now relying on modern C features that cc65 doesn't support). I currently concentrate on getting LilyVM to do anything useful for me on modern systems. (I've got some more work that I haven't pushed yet; but I mainly need to finally start working on the compiler to bytecode, which is a larger can of worms than the VM. I might first re-implement Copycat on it.)
