I stand by Comments 6 and 7 of
[1].
Summary: The only way I can see fast paths working well without very very intricate programming (including round off error tracking etc) and without making the image "jump" in some situations is to make absolutely sure that the branching to the fast path occurs at a high enough level that any generic tool that can perform something which is "almost but not quite" the operation that the fast path performs never follows the fast path.
