I just gave a run of examples/assembly/mops_p.pasm, getting some

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?
CG vs JIT (running with non jitted opcdes) wins CG, always.
Ah, OK. No function preambles/postambles in the CG case. Hrm, time to
go learn PPC assembly, I guess... :)
IBM hosts a tutorial on Linux PowerPC assembly, with links to
instruction set, ABI, and optimization:

Yow! Cool, thanks!
