--- Comment #2 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
With the patch, the avr.md::divmodhi4 insn reads like this:
(define_insn_and_split "divmodhi4"
[(set (match_operand:HI 0 "register_operand" "={r22}")
(div:HI (match_operand:HI 1 "register_operand" "{r24}")
(match_operand:HI 2 "register_operand" "{r22}")))
(set (match_operand:HI 3 "register_operand" "={r24}")
(mod:HI (match_dup 1)
(match_dup 2)))
(clobber (match_scratch:HI 4 "={r26}"))
(clobber (match_scratch:QI 5 "={r21}"))]
""
"#"
"&& reload_completed"
[(scratch)]
{ DONE_ADD_CCC })
