--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
 I spent good part of day today trying to recollect what was motivation for the
change.  All i can think of is that it was mistaken micro-optimization as
mentioned in the mail I sent about reverting the patch.

I plan to backport the change if performance turns out to be OK.
