- Subject: [PATCH, AVR] Change opcode set for avr3 architecture.
This patch changes the opcode set for the avr3 architecture and for two
recently added devices. This change is needed to support the new avr35
architecture (in between avr3 and avr4) being added to gcc.
Thanks,
Eric Weddington

* config/tc-avr.c (mcu_types): Change opcode set for avr3,
at90usb82, at90usb162.
* doc/c-avr.texi: Change architecture grouping for at90usb82,
at90usb162.
These changes support the new avr35 architecture group in gcc.
