================
Comment at: llvm/lib/Target/X86/X86FixupBWInsts.cpp:220
+  for (auto &MO: MI.implicit_operands()) {
+    if (!MO.isReg() || (!MO.isDef() && !MO.isUse()))
+      continue;
----------------
I don't think the isDef and isUse check is necessary. An operand is either a use or a def. There's no third state.
