[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...
