            Bug ID: 91069
           Summary: [10 Regression] Miscompare of 453.povray since r272843
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
  Target Milestone: ---

Starting from the commit following fails:

$ runspec --config=spec2006 --size=test --iterations=1  --no-reportable
--action run --tune=peak 453.povray

with -Ofast -march=native -g on a znver1 machine. I'll reduce that.
