instruct replicate2L_zero(vecX dst, immI0 zero)
%{
predicate(UseSVE == 0 && n->as_Vector()->length() == 2);
match(Set dst (ReplicateI zero));
ins_cost(INSN_COST);
format %{ "movi $dst, $zero\t# vector (4I)" %}
ins_encode %{
__ eor(as_FloatRegister($dst$$reg), __ T16B,
as_FloatRegister($dst$$reg),
as_FloatRegister($dst$$reg));
%}
ins_pipe(vmovi_reg_imm128);
%}
This rule outputs vecX, however, it matches ReplicateI node. Should it be ReplicateL?
