[llvm-dev] Understanding assert in SelectionDAGBuilder.cpp

[jeniffer lesley via llvm-dev]

Hi,
I am new to LLVM. I am experimenting with a toy backend. I don't understand
"LowerFormalArguments didn't return a valid chain" in
SelectionDAGBuilder.cpp file. What is the interface here? What does it mean
by returning a Chain?

Thanks
Jen.
