attributes can be any superset of the iterator, so you don't need two
separate attributes here.
;; As above but in lower case.
(define_mode_attr V_cvtto [V2SI "v2sf") (V2SF "v2si")
(V4SI "v4sf") (V4SF "v4si")])
is perfectly adequate and matches other attributes in the ARM back-end.
The ARM bits are OK with that change.
