================
Comment at: lib/Target/X86/X86ISelLowering.cpp:26605
+          .addImm(4)
+          .addReg(IReg64)
+          .addImm(0)
----------------
If building with optimizations, this works as intended. If building without optimizations, this actually uses another, uninitialized register here instead of IReg expanded to 64 bit (as done with `TargetOpcode::COPY` above). Does anybody happen to have a hint about why that happens?
