--- Comment #15 from Martin Liška <marxin at gcc dot gnu.org> ---
I can confirm that on my Haswell machine:
model name : Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz
I see regression with -march=core2 -mtune=core2 -O3 starting from r226901
(first time in GCC 5.x).
Time difference is:
0:00:14.975390
vs
0:00:11.889274
