[LLVMdev] widen_load fails on AVX
...;& 2*Lo.getValueType().getVectorNumElements() == Op.getValueType().getVectorNumElements() && Hi.getValueType() == Lo.getValueType() && "Invalid type for split vector"' failed.
The illegal CONCAT_VECTOR node is created from
LegalizeVectorTypes.cpp
DAGTypeLegalizer::GenWidenVectorLoads()
I saw that this code comes from your commit 112171
this is the reduced test
