[LLVMdev] Some questions on SelectionDAG
Hi, all
I am studying the ARM backend on SelectionDAG, I have some following
questions:
1. Each operator of SDNode in SelectionDAG is required to be defined by
SDNode<ISD::XXX,XXX,XXX> in .td file, right?
But several operators are not defined in .td file, why? (e.g., ISD::BR_CC,
ISD::CopyToReg, ISD::AssertSext)
2. The MVT::glue value is used to ensure two nodes are scheduled
