================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:21223
   // Promote i32 to i64 and use a signed conversion on 64-bit targets.
   if (SrcVT == MVT::i32 && Subtarget.is64Bit()) {
     Src = DAG.getNode(ISD::ZERO_EXTEND, dl, MVT::i64, Src);
----------------
Here, i32 will be promoted to i64 for 64-bit target.
