[llvm-dev] Understanding TargetLowering::LowerCall

[Zhang via llvm-dev]

For CallSites that contains a GlobalValue as one of the arguments, where exactly does the lowering from GlobalAddress to iPTR took place?.


I'm assuming it should be handled in TargetLowering::LowerCall where target-dependent DAG Nodes got created depending on CCValAssign::isRegLoc() but from my testing it seems like isRegLoc() is true even for GlobalAddress arguments.


What am I misunderstanding here?
