search for: dupnode

Hi, Joseph, I guess getLoad() will either search an existed SDValue *OR* create a new one for a non-existed one depending on real parameters. Since you use exactly the same attributes dupVal/dupNode have, no doubt getLoad() return the old one. I am not sure it's *volatile* that let you get a new result, you might want to try change some other parameters and check what it turns out.

So I think I have made some progress. SDValue dupVal = consumer->getOperand(OpNo); LoadSDNode *dupNode = (LoadSDNode*) dupVal.getNode(); SDValue newLoad = CurDAG->getLoad(dupVal.getValueType(), dupVal.getDebugLoc(), dupVal.getOperand(0), dupVal.getOperand(1), dupNode->getPointerInfo(), dupNode->isV...

Hi, I am writing an llvm target and I need both loads for isel reasons, but I am struggling to find the right way. I have been trying to use DAG.getLoad() to make a copy, then just change the operand in the consumers, but I cannot seem to get all of the arguments needed for that function in order to make the copy. Any help would be great, thanks! -Joe -------------- next part -------------- An
