--- Comment #19 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am even seeing almost 10% performance drop from GCC 7 to the trunk even. Even
at -O2.  This is on an OcteonTX2:
-O2:
7.4.0:
2150.408184
trunk:
2032.971945

-O2  -fno-tree-vectorize:
trunk:
2028.648257

-O3:
7.4.0:
2207.640167
trunk:
2049.228275
