RKSimon added inline comments.


================
Comment at: llvm/test/Transforms/SLPVectorizer/X86/pr47629.ll:17
+; CHECK-NEXT:    store <4 x i32> [[TMP11]], <4 x i32>* [[TMP12]], align 4
 ; CHECK-NEXT:    ret void
 ;
----------------
This doesn't look great in the final codegen: https://gcc.godbolt.org/z/vE9Yoe

Which suggests either the costs aren't correct or we're not correctly including the cost of something - the buildvector of the pointers? are we missing getelementptr vectorization?
