Yes, I think that was it. Thanks.
Also, checking the slides more carefully I was able to answer
one of my questions:
How to declare your processor supports 3 operands instructions ?
By default the jit generates 3 operands instructios.
For architectures supporting only 2 operands, add a line
#define TWO_OPERAND
in config/<arch>/jit.h.
BTW, a comment in config/m68k/jit.h says TWO_OPERAND specify
your architecture supports 2 operands instructions "rather than one"
(I guess it was a 'rather than three')
thanks,
Raffaele
