--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> --- The regression in the original description looks severe enough to warrant some fixing even if regressing some other cases. I agree it's the aarch64 maintainers decision what to do for GCC 6. But please don't downgrade bugs to P4 but instead re-target them to GCC 7, adding /7 to the regression marker in the summary. RMs then can then categorize this bugs priority properly to P2 (P3 is just "no categorization done yet").
