            Bug ID: 81280
           Summary: bid_conf.h:37:21: note: non-delegitimized UNSPEC
                    UNSPEC_GOT (0) found in variable location
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

Recent x86_64 bootstrap has been issuing the following notes (I see no warning
or error in the logs).  I don't see anything about this instance of the note in
Bugzilla (there are bugs about other instances of it, such as the resolved
pr45870 and pr61879, and pr63542 which points to a different location in the
same file).
