--- Comment #30 from PeteVine <tulipawn at gmail dot com> --- Or rather, the difference observed in: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77468#c7 is still there @ -Ofast, but the Cortex-A53 result is in the same range now. I'll have to investigate the effect of --fix-cortex-a53-835769 that was always passed by default in the other image.
