I believe the VIA C3 had an undocumented feature to allow executing the

Such as every x86 processor since, what, the
Pentium? They're all
RISC cores (designed for and) running an x86 emulator.
I've been told this more than a few times and read it in various places.
It always make me wonder, could we not allow a mode in modern Intel
processors that lets us bypass the x86 code emulation/translation and
run "directly on the metal" (if there were such a thing).
