[avr-gcc-list] AT90USB82 / AT90USB162 architecture?

[Paulo Marques]

Hi all,

I was trying to determine if these devices have multiply instructions or 
not.

The datasheet doesn't show any MUL* instructions in the "Instruction Set 
Summary" section, but the avr-libc documentation pages at:

http://www.nongnu.org/avr-libc/user-manual/using_tools.html

show these devices as "avr5" which has multiply instructions, and at 
least avr-gcc 4.2.2 also emits multiply instructions for these devices.

Note that the AT90USB64x/128x variants do have MUL* instructions in 
their datasheets.

Is this a bug in the current tools (binutils/gcc/documentation)?
