<div>Hi,</div>
<div> </div>
<div>We have a function in IRBuilder.h </div>
<div><font face="Consolas" color="#2B91AF">Value<font color="black"> *CreateVectorSplat(</font><font color="blue">unsigned</font><font color="black"> </font><font color="gray">NumElts</font><font color="black">, </font>Value<font color="black"> *</font><font color="gray">V</font><font color="black">,
</font><font color="blue">const</font><font color="black"> </font>Twine<font color="black"> &</font><font color="gray">Name</font><font color="black"> = </font><font color="#A31515">""</font><font color="black">) {</font></font></div>
<div><font face="Consolas">..</font></div>
<div><font face="Consolas">}</font></div>
<div><font face="Consolas"> </font></div>
<div>This function creates 2 instructions - “insertelement” and “shuffle” with all-zero mask.</div>
<div> </div>
<div>Now I want to add</div>
<div>Value *getSplatValue(Value *Val). This function will try to recognize the pattern - insertelement+shuffle and return the splat value (or nullptr).</div>
<div>I suppose, this interface should be useful. Do you agree with me?</div>
<div> </div>
<div>If yes, where should I put it? May it be I can define a new class VectorInst and put this interface there?</div>
<div>Thank you.</div>
<div> </div>
<div> </div>
