--- Comment #3 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
(define_expand "vec_init<mode><unitmode>"
  [(match_operand:LSX 0 "register_operand")
   (match_operand:LSX 1 "")] 
  "ISA_HAS_LSX"
{
  loongarch_expand_vector_init (operands[0], operands[1]);
  DONE;
})

We need to add a predicate for operand 1...
