Things start to get interesting. The first two vtable slots are gone.
The dispatch for the Cbxor PMC opcodes is now down fully per MMD.
The MMD_BXOR and MMD_BXOR_INT MMD slots are just adjacent entries in the
function table. This is the simplest implementation and provides good
cache locality
The change happened on 2004-05-10 between 07:05 and
07:10 EDT. The files that changed during that time
frame are
lib/Parrot/Pmc2c.pm

Looking at the diffs, the only change I can see is to

Ah. yep. Due to eliminating two vtable functions, other ones after that
moved down in table. JIT needs a small adjustment.

Looks OK.
Fine.
Interesting is the dispatch inside objects. These have a delegate
vtable which runs a PASM function.

All of the current and future changes during shifting vtable functions

I have written a gcd op that takes 5 arguments (3 out, 2 in)
gcd d, x, y, a, b

This op can be useful for some cryptographic stuff, should I check it in?
