--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
badness being a very small negative number is actually normal for large
functions like this one (perhaps I should print it better though). I can check
from where the estimated speedup comes - perhaps we work out some loop
invariants
and thus anticipate invariant motion?

Actually it is visible from the dump
Scaling time by probability:0.000000
means that we expect quite few values to be "almost invariant". It may come
from busted BB profile of course.
