I'm doing that check later. The reason I wanted to avoid doing it in the first if, is that either it will mean int_size_in_bytes needs to be called twice, or we'd need (size = int_size_in_bytes (TREE_TYPE (exp))) > 0 (i.e. setting variables in the if condition). But if you prefer one of these, I'll adjust.
