Thanks. It was a surpise for me, that avr2 (and avr3 now)
are different for avr-gcc and avr-as.
And what is an advantage of a difference of avr2 architecture
for avr-gcc and for avr-as? Is it a bug, that avr-gcc
translate '-mmcu=avr2' option into the same '-mmcu=avr2'
avr-as option? (For avr-gcc 'avr2' is the avr2-relocation
and the classic instruction set. For avr-as 'avr2' is also
avr2-relocation, but the enhanced instruction set without
multiplication.)
IMHO, it would be better to permit for avr-as the '-mmcu=avr25'
option: which is alias for 'avr2' in relocation and is
differ in instruction set. (The same for avr35/avr3).
Dmitry.
