------- Additional Comments From fjahanian at apple dot com 2004-12-10 01:42 ------- AFAICT, I don't see how gcc middle-end can force correct parameter alignment when alignment is more strict than PARAM_BOUNDARY. There is no code to do so (I am looking at store_one_arg which is the one responsible for determining the alignment). It does set the MEM_ALIGN field to 128 in this case, but there is no extra padding to move the target address to the next 128 bit boundary.
