Glue to connect two nodes in LLVM backend
...|
ADDI ----GLUE---- ADDI
|
store
I've few question about this and Glue node in general, I'll be happy to get
some help on this :)
1. Is Gluing the right approach or there is something better for such use
case?
2. If I do something like DAG.getNode(ISD::ADDI, DL, MVT::Glue, LUINode,
OtherADDINode). How will it know that the other ADDI node should be glued
and not LUI. I seriously feel I'm missing something.
Many thanks,
Reshabh
