Gluing arbitrary nodes together
...ok to convert ISD::ATOMIC_LOAD into a standard
ISD::LOAD with the save/restore/interrupt nodes glued to it.
Here’s what I have so far:
// Store `SREG`
auto Save = DAG.getCopyFromReg(DAG.getEntryNode(), DL, AVR::SREG, MVT::i8);
// Disable interrupts (`clr` is equivalent to `bclr 7`).
auto ClearInterrupts = DAG.getNode(AVRISD::BCLR, DL, MVT::Glue,
DAG.getConstant(7, DL, MVT::i8));
// Perform the nonatomic load.
auto *Node = cast<AtomicSDNode>(AtomicOp.getNode());
SDValue Load = DAG.getExtLoad(ISD::EXTLOAD, SDLoc(AtomicOp),
AtomicOp.getValueType(),
Node...
