PR22336 (was: Problem with tree-ssa-loop-ivopts.c:get_computation-cost)

[Richard Kenner]

    I think the patch is fine (although of course I cannot approve it).  

I, as it's author, do not.  But, as I keep saying, I don't know what
the proper fix is.

    The more proper fix would be to never expand such expressions from ivopts;

What are "such expressions"?
