>From expr.c:count_type_elements:
case UNION_TYPE:
case QUAL_UNION_TYPE:
{
/* Ho hum. How in the world do we guess here? Clearly it isn't
right to count the fields. Guess based on the number of words. */
HOST_WIDE_INT n = int_size_in_bytes (type);
if (n < 0)
return -1;
return n / UNITS_PER_WORD;
}
So we cannot use count_type_elements in gimplify_init_constructor.
I think we should somehow compute the size of the CONSTRUCTOR and compare
it with int_size_in_bytes (TREE_TYPE (object))...?
