[LLVMdev] widen_load fails on AVX
...lueType() == 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
define void @add18i16(<18 x i16>* nocapture sret %ret, <18 x i16>* %bp) nounwind {
%b = load <18 x i16>* %bp, align 16
%x = add <18 x i16> zeroinitializer, %b
store <18 x i16> %x, <18 x i16>* %ret, align 16
ret void
}
Could you take a look, please.
Thanks.
