--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> ---
On more recent trunk -fno-split-paths makes only a tiny difference (4882 vs.
4779 Mflops) while -ftree-loop-if-convert still results in 5432 Mflops. GCC 6
scores 5523 Mflops for me (-O3 -march=native on a Broadwell CPU).
Marking as regression.
