--- Comment #9 from Steven Bosscher <steven at gcc dot gnu.org> 2012-10-29 23:54:10 UTC ---
Can you please also attach the output of -fdump-ipa-profile-all
which should be eval.c.041i.profile. I have my dump here, it should
be the same as yours.

Are you working on a 32-bit host? The counts are quite high, there
are some places where the count is multiplied by REG_BR_PROB_BASE
which is 10000.  The highest count in my .profile dump is 42974935,
if such high counts are multiplied somewhere for scaling then this
may be an overflow issue that I can't see on powerpc64.
