Comment at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:808
+ Value *GEP = GetElementPtrInst::CreateInBounds(
+ SI->getPointerOperand(), {ConstantInt::get(Idx->getType(), 0), Idx});
+ Builder.Insert(GEP);
----------------
Technically, size of the `insertelement` index doesn't have to match the size of the GEP index,
the latter is controlled in datalayout. I'm not sure if/how we need to deal with that here, however.
