----------------
Please change this to:

    if (Out.EmitValueToOffset(Value, 0)) {
      Error(EqualLoc, "expected assembly-time absolute expression in assignment to psuedo-symbol '.'");
      eatToEndOfStatement();
    }
    return false;

Error will return true, and then generate a secondary diagnostic improperly otherwise.
