Padding is only inserted:
Within load regions. No padding is present between load regions.
Between fixed execution regions (in addition to forcing alignment). Padding is not inserted up to the maximum length of a load region unless it has a fixed execution region at the top.
Between sections to ensure that they conform to alignment constraints.
