You don't need these.
Just reverse the operands to the existing tcg_gen_mulsu2_*.

Ok, I'm just trying to unify  "u * s " to the macros VMUL_Q and VMADD_Q.

Then create local wrappers:

void tcg_gen_mulus2_i64(TCGv_i64 rl, TCGv_i64 rh, TCGv_i64 arg1, TCGv_i64 arg2)

{
    tcg_gen_mulsu2_i64(rl, rh, arg2, arg1);
}

Ah,  got it.

Thanks.
