That's awesome. 40 years ago people would have killed for such (I myself included, if it were for Z80 instead of 6502). But why? I know better then to ask for such projects, but here I do, because the project's readme provides a 'history & motivation' section, albeit which doesn't really tells much of the latter. "The original idea for the oscar64 compiler was to translate the C source to an intermediate 16 bit byte code". That's (afair) the approach taken by the (out-of-tree) GCC port to the Parallax P8X32A (itself not an easy target for C: registers, if one wants to call the local memory location used as such that are wide, but the architecture is memory starved and there's no hardware stack). Is there some overlap?
