--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
This is predcom. It's easier to see what's going wrong with
#pragma GCC unroll 99
added to the innermost loop so it's unrolled at -O2 and comparing
g++ -O2 -fpredictive-commoning --param=max-unroll-times=1
vs. plain g++ -O2 (or diffing 'pcom' dump against the preceding pass).
