ARMISelDAGToDAG.cpp had this self-contradictory code:

  return StringSwitch<int>(Flags)
          .Case("g", 0x1)
          .Case("nzcvq", 0x2)
          .Case("nzcvqg", 0x3)
          .Default(-1);
...

  // The _g and _nzcvqg versions are only valid if the DSP extension is
  // available.
  if (!Subtarget->hasThumb2DSP() && (Mask & 0x2))
    return -1;

ARMARM confirms that the comment is right, and the code was wrong.
