[LLVMdev] Splitting a load with 2 consumers into 2 loads.
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.
Regards.

[LLVMdev] Splitting a load with 2 consumers into 2 loads.
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->is...

[LLVMdev] Splitting a load with 2 consumers into 2 loads.
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!
