llvm dev - Nov 2019 - getelementptr confusion

Hi,
The original scalar GEP:   

%scevgep = getelementptr i16, i16* %A, i32 %conv12



After adding bitcast vector it:  

<1 x i16&gt;*%scevgep = getelementptr <1 x i16&gt;,&nbsp; i16*
%A, <1 x i32&gt; %conv12



I want to scalar them back for gelementptr address calculation, then vector the
lowered ISDNode again.&nbsp;

void SelectionDAGBuilder::visitGetElementPtr(const User &amp;I)&nbsp;
only supply const interface which make this hack very hard.


Any suggestion?
