Hi,

We would have to change opcode.h for this to be truely useful (in order
to re-use OPCODE_LIST()). I think that should be the subject of a
separate bug entry for code reorganization.

Thanks for all the explanation and pointers! About register allocation,
I wonder if the "temporary variables" u,v,w could be declared separately
in each opcode rather than at the top of the eval function, so that the
compiler doesn't try to store their values between two opcodes.

As for the "register" declarations, I think they're just remains of the
past.

Antoine.
