示例1: doBinaryOperationArray

  //unlike NodeBinaryOp, NodeBinaryOpCompare has a node type that's different from
  // its nodes, where left and right nodes are casted to be the same.
  bool NodeBinaryOpCompare::doBinaryOperationArray(s32 lslot, s32 rslot, u32 slots)
  {
    assert(0); //not implemented yet..TODO return bool.
    UlamValue rtnUV;
    UTI nuti = getNodeType(); //Bool, same array size as lhs/rhs

    UTI luti = m_nodeLeft->getNodeType();
    UTI ruti = m_nodeRight->getNodeType();
    s32 arraysize = m_state.getArraySize(luti);

    assert(arraysize = m_state.getArraySize(nuti)); //node is same array size as lhs/rhs

    s32 bitsize = m_state.getBitSize(luti);
    UTI scalartypidx = m_state.getUlamTypeAsScalar(luti);
    PACKFIT packRtn = m_state.determinePackable(nuti);

    if(WritePacked(packRtn))
      {
	// pack result too. (slot size known ahead of time)
	rtnUV = UlamValue::makeAtom(nuti); //accumulate result here
      }

    // point to base array slots, packedness determines its 'pos'
    UlamValue lArrayPtr = UlamValue::makePtr(lslot, EVALRETURN, luti, packRtn, m_state);
    UlamValue rArrayPtr = UlamValue::makePtr(rslot, EVALRETURN, ruti, packRtn, m_state);

    // to use incrementPtr(), 'pos' depends on packedness
    UlamValue lp = UlamValue::makeScalarPtr(lArrayPtr, m_state);
    UlamValue rp = UlamValue::makeScalarPtr(rArrayPtr, m_state);

    //make immediate result for each element inside loop
    for(s32 i = 0; i < arraysize; i++)
      {
	UlamValue luv = m_state.getPtrTarget(lp);
	UlamValue ruv = m_state.getPtrTarget(rp);

	u32 ldata = luv.getData(lp.getPtrPos(), bitsize); //'pos' doesn't vary for unpacked
	u32 rdata = ruv.getData(rp.getPtrPos(), bitsize); //'pos' doesn't vary for unpacked

	if(WritePacked(packRtn))
	  //use calc position where base [0] is furthest from the end.
	  appendBinaryOp(rtnUV, ldata, rdata, (BITSPERATOM-(bitsize * (arraysize - i))), bitsize);
	else
	  {
	    rtnUV = makeImmediateBinaryOp(scalartypidx, ldata, rdata, bitsize);

	    //cp result UV to stack, -1 (first array element deepest) relative to current frame pointer
	    m_state.m_nodeEvalStack.storeUlamValueInSlot(rtnUV, -slots + i);
	  }
	assert(lp.incrementPtr(m_state));
	assert(rp.incrementPtr(m_state));
      } //forloop

    if(WritePacked(packRtn))
      m_state.m_nodeEvalStack.storeUlamValueInSlot(rtnUV, -1); //store accumulated packed result

    return false;
  } //end dobinaryoparray
