--- Comment #3 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
This issue is a side effect of PR34307 where the assembler diagnoses the wrong
instruction when a core doesn't support it: It diagnoses with the NEXT
instruction, which lead to a segmentation fault in old Binutils when DES was
the last instruction in include/opcode/avr.
Since PR21683 DES is no more the last instruction, so the seg fault is fixed by
PR21683 as a side effect. Though until PR34307 is fixed, gas will show a
confusing diagnostic:
DES
x.sx: Assembler messages:
x.sx:1: Error: illegal opcode __gcc_isr for mcu avr2
