--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yes, tail-merging needs to utilize a "value-numbering" like IPA ICF (in fact,
just re-use its implementation - I think this is what Martins patch set does).
My cleanup comment was supposed to be the first cleanup _after_ that patch-set
is merged.
