I want to get MEM of non-BLKmode folded to MEM of BLKmode.
I already changedit to adjust_address_nv in the patch I am re-testing. I will
post once testing finished.
(simplify_gen_subreg actually traps for BLKmode and correctly so)
I do not think we can get PARALLEL here and thus use of adjust_address_nv as
follows seems to be right
trick:
if (GET_MODE (temp) == BLKmode && GET_MODE (target) != BLKmode)
{
gcc_assert (AGGREGATE_TYPE_P (TREE_TYPE (exp)));
gcc_assert (MEM_P (temp));
temp = adjust_address_nv (temp, GET_MODE (target), 0);
}
