In principle the same way as a RISC compiler handles higher level
instructions.
Though it may be that modern Intel or AMD chips do not have enough
registers.
Somewhere I got the impression that Athlon and AMD and the Pentium chips
were RISC chips with a hardware layer which converted Intel instructions to
RISC instructions, but that may have changed if it existed. If so could one
access the RISC instructions and registers directly?

Does that mean to say QPC is an emulator in principle?
Does that mean that QPC runs a lot slower because of the emulation?

Which should come first for QPC?
JIT
6020+ & FPU emulation

I suppose the answer depends on what do your customers use the QL for?
Probably tinkering and hence the answer neither.
