No, it would mean a *change* in the compiler.

That is what I meant.

If little-used
instructions had to be dropped to leave room in the instruction space for
the additional features, then you break backwards compatibility. But
that's hardly something new - small breakages occur with changes to the
memory maps, the introduction of the 3-byte return stack, and the
differences to the eeprom access methods for every new generation of AVR.

Taking advantage of the new instructions would mean a fair number of
changes to compilers - but there would be no problem generating correct
code.



I think it is all related to project management/resources.
Even if things are not perfect, it may be considered good enough,
and that resources are better used elsewhere.

Would Atmel benefit, by introducing a few more instructions,
and delay the introduction of the X-mega by 1 month/3 months/6 months a
year?
