I just gave a run of examples/assembly/mops_p.pasm, getting some performance numbers. Here's an interesting timing.$ languages/imcc/imcc examples/assembly/mops_p.pasm

This is... odd. And on PPC, FWIW, and I'm not sure if it happens on x86.
Someone care to check it out and poke around a bit?

It depends on implemented functions in JIT. i386 has a bunch of vtable functions JITed (which isn't too hard to do).
