Hi,

-instruct rsmax4S_reduction_reg(rRegI dst, rRegI src1, vecD src2, regF tmp, rRegI tmp2, rRegI tmp3) %{

   predicate(UseSSE > 1 && n->in(2)->bottom_type()->is_vect()->element_basic_type() == T_SHORT);
   match(Set dst (MaxReductionV src1 src2));
   effect(TEMP tmp, TEMP tmp2, TEMP tmp3);
   format %{ "pshufd  $tmp,$src2,0x1\n\t"
             "pminsw  $tmp,$src2\n\t"

s/pminsw/pmaxsw. ?
