            Bug ID: 102828
           Summary: [12 Regression] ODR violation in
                    gimple-predicate-analysis.h since g:94c12ffac234
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: msebor at gcc dot gnu.org
  Target Milestone: ---

I noticed that during bootstrap and I think we should not introduce new ODR
violations, it may break LTO bootstrap.
