--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
As said in the other PR, this is more for Honza who thought checking we do not
end with invalid profiles for all vect testcases is a good thing ;)
Btw, the wrong count pops up in DOM3:
t.c.203t.dom3:;; Invalid sum of incoming counts 138435014 (estimated locally,
freq 3.0936), should be 134239200 (estimated locally, freq 2.9999)
so it seems to be a jump threading issue. It's gone with -fno-thread-jumps.
Very likely a latent issue, but of course the change triggering this does
have an effect on jump threading.
Confirmed.
