Thanks, LGTM with my nit addressed.



================
Comment at: llvm/lib/Analysis/InstructionSimplify.cpp:4495
       return PoisonValue::get(VecVTy->getElementType());
+    // It handle cases where splat is the operand of the extract
+    if (IdxC->getValue().ult(MinNumElts))
----------------
nit: Handle case where an element is extracted from a splat.
