> Why is it always allocating the register spill area? In a simple little test case, I was able to verify that, if that code was removed, the register parameters would properly get saved to their shadow space.
Yes, they are saved, but someone should allocate space for them :)
Otherwise they will overwrite / can be overwritten by other stuff.
