             Bug #: 13959
           Summary: Clang can't recognize -Wp,-MMD
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: carrot at google.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


When I put -MMD behind -Wp, clang reports -MMD is an unknown argument.

$clang -fsyntax-only -Wp,-MMD  t2.c
error: unknown argument: '-MMD'

If I use -MMD separately, clang happily accepts it.

$clang -fsyntax-only -MMD  t2.c

So it is a problem of -Wp.
