In fact, there's no reason at all to define a helper function for this one. I would expect you do be able to use the exact same helpers as for the integer merges.
Do you mean that I should expands TCGv to TCGv_i64 for vmv.v.x in translation?
So that I can reuse it. void gen_helper_vmv_v_x(TCG_ptr, TCGv_i64, TCGv_env, TCGv_i32); Zhiwei
