Actually, when I said "see the default definition of the length attribute",
I was talking this in mips.md:
(define_attr "length" ""
(cond [...
(and (eq_attr "type" "idiv")
(ne (symbol_ref "TARGET_CHECK_ZERO_DIV") (const_int 0)))
(cond [(ne (symbol_ref "TARGET_MIPS16") (const_int 0))
(const_int 12)]
(const_int 16))
...
] (const_int 4)))
