            Bug ID: 82694
           Summary: [8 regression] Linux kernel miscompiled since r250765
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trippels at gcc dot gnu.org
                CC: amker at gcc dot gnu.org
  Target Milestone: ---

Since r250765 the Linux kernel gets miscompiled when built with -O3.
It hangs very early during boot waiting for an interrupt that never occurs
(hlt in early_fixup_exception()).

I haven't looked deeper yet, so sorry no testcase.
