            Bug ID: 103425
           Summary: 48% tramp3d regression between g:df1a0d526e2e4c75 and
                    g:9e026da720091704 with  -Ofast -march=native at Zen
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hubicka at gcc dot gnu.org
  Target Milestone: ---

visible at https://lnt.opensuse.org/db_default/v4/CPP/graph?plot.0=171.576.0
and with LTO https://lnt.opensuse.org/db_default/v4/CPP/graph?plot.0=178.576.0

It lasts for 2 runs already so probably not a noise.  Curiously I do not see it
on other testers (perhaps they need to run yet)
