If it's only read, it's constant propagated everywhere and the situation is exactly the same as before (arguably not perfect, but still). Otherwise, you have it in a register and you're happy. + Only situation where this is *worse* is if that temp is then spilled. This is only one memory move at the function entry then, which is not that bad. |
