--- Comment #9 from Daniel Fruzynski <bugzilla@poradnik-webmastera.com> ---
I have idea about alternate approach to this. gcc could try to look for
relations between loop control statement, and other statements which modify
variables used in that control statement. With such knowledge it could try to
reorganize code to better optimize it. This approach would eliminate randomness
here.
