Yes (#2 in my list), but a controlled kind so it doesn't suffer from the
maintainability issues of explicitly modified instructions. But it does
require I-cache management, if the computer has an I-cache. Not all that
likely; a machine small enough that overlays are valuable isn't all that likely
to have an I-cache.
