[LLVMdev] [Target] Custom Lowering expansion of 32-bit ISD::SHL, ISD::SHR without barrel shifter
...Thus, I wish to mark ISD::SHL/SHR as "Custom" in setOperationAction(), but I'm unsure of how to manually split the 32-bit shiftee SDValue into two 16-bit values. The standard logic in /lib/CodeGen/SelectionDAG/LegalizeTypes.cpp and LegalizeIntegerTypes.cpp has a member function called GetExpandedInteger(). Unfortunately, this is a private method, so I can't gain access to this without hacking on code outside of my target's (/lib/Target/x65 in this case). To be 100% clear, I actually already did attempt this route, and when compiling received an error that GetExpandedInteger was a private...
