           Summary: Warn if -coverage is passed (and debug info are not
                    present)
           Product: clang

            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

Gcov data is useless without debug info so we should error/warn if -coverage is
passed but -g is not.
