----------------
Since you already post D129861, you can show diff based on D129861 and make this patch be a child of that patch.


================
Comment at: llvm/test/CodeGen/PowerPC/load-and-splat.ll:1475
+  %vec = load <8 x float>, <8 x float>* %vp
+  %res = shufflevector <8 x float> %vec, <8 x float> undef, <8 x i32> <i32 0, i32 0, i32 0, i32 0, i32 5, i32 0, i32 0, i32 0>
+  ret <8 x float> %res
----------------
Can we also get improvement for a normal vector type, like <4 x float> or <2 x double>?
