           Summary: Clang's Sema::ActOnEndOfTranslationUnit completes
                    tentative decls in nondeterminstic order
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: [email protected]
        ReportedBy: [email protected]

While investigating PR4888, I discovered that Sema::ActOnEndOfTranslationUnit
is completing tentative definitions in DenseMap iteration order, leading to
nondeterminstic generated code.  This is badness.  One possible fix is to have
Sema put tentative definitions in a vector as well as the densemap, and then
emit in vector order.
