------- Comment #1 from pinskia at gcc dot gnu dot org 2006-05-31 16:50 -------
Maybe:
(define_insn "altivec_vspltisw_v4sf"
[(set (match_operand:V4SF 0 "register_operand" "=v")
(vec_duplicate:V4SF
(subreg:SF (match_operand:QI 1 "s5bit_cint_operand" "i"))))]
OR something like that, even though it is not a subregister, it should still
work I think ?
