            Bug ID: 86004
           Summary: [9 regression] Several lto test cases begin failing
                    with r260963
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

This started with r260963 but that specific revision won't build properly
because of an error in a previous revision.  I am not sure if the test cases
just need updating (an option was changed on at least some of them).

I saw this on powerpc64 but it also fails on a check of one of them on x86.
