codes. TCG will be able to use host registers to store them.
-- Free temporaries when they are no longer used (``tcg_temp_free``).
- Since ``tcg_const_x`` also creates a temporary, you should free it
- after it is used.

- Don't hesitate to use helpers for complicated or seldom used guest
instructions. There is little performance advantage in using TCG to
implement guest instructions taking more than about twenty TCG
