Dear LLVM, I'm trying to understand why the attached IR code works for x86_64 target and fails for nvptx64, because of unimplemented expand during the target lowering. Any ideas? Just change the target triple to x86_64-unknown-unknown, and the same IR code could we successfully codegen-ed for x86_64.
