[LLVMdev] Isel DAG documentation?
...;d want that Dst globaladdr to be a tglobaladdr (target globaladdr)
since LLVM knows it shouldn't try to select target nodes. Existing
targets mostly do that during ISelLowering for various reasons, but
for your case a separate pattern can probably do the job:
def : Pat<(globaladdr:$addr), (MOVar tglobaladdr:$addr)>;
