--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> --- So I tested this with a one-off run of SPEC CPU 2006 on a Haswell machine which shows the expected improvement on 416.gamess but also eventual regressions for 433.milc (340s -> 343s), 450.soplex (223s -> 226s) and 482.sphinx3 (383s -> 391s). Re-checking those with a 3-run now.
