[PATCH] D117426: [AVR] Only push and clear R1 in interrupts when necessary

[Ayke via Phabricator via llvm-commits]

aykevl added inline comments.


================
Comment at: llvm/lib/Target/AVR/AVRExpandPseudoInsts.cpp:1347

================
Comment at: llvm/lib/Target/AVR/AVRISelLowering.cpp:821
 
+// Modify the existing ISD::INLINEASM node to add the implicit register r1.
+SDValue AVRTargetLowering::LowerINLINEASM(SDValue Op, SelectionDAG &DAG) const {
----------------
This is a bit of a hack, but I couldn't think of a better way.
