```
(define_insn "negv<GPI:mode>_cmp_only"
[(set (reg:CC_V CC_REGNUM)
(compare:CC_V
(sign_extend:<DWI>
(neg:GPI (match_operand:GPI 0 "register_operand" "r")))
(neg:<DWI> (sign_extend:<DWI> (match_dup 0)))))]
""
"negs\\t%<w>zr, %<w>0"
[(set_attr "type" "alus_sreg")]
)
```
`%<w>zr` is wrong; it should just be `<w>zr` without the %.
