<p class="MsoNormal">I have two registers A and B that are aliases of each other. I have not found a way to define this in tablegen yet. Would anyone know how?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve tried:<o:p></o:p></p>
<p class="MsoNormal">def A : Register<”%a”>;<o:p></o:p></p>
<p class="MsoNormal">def B : Register<”%b”>;<o:p></o:p></p>
<p class="MsoNormal">let Aliases = [A] in {<o:p></o:p></p>
<p class="MsoNormal">B;<o:p></o:p></p>
<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal">let Aliases = [B] in {<o:p></o:p></p>
<p class="MsoNormal">A;<o:p></o:p></p>
<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve also tried forward definitions.<o:p></o:p></p>
<p class="MsoNormal">def A;<o:p></o:p></p>
<p class="MsoNormal">def B : RegisterWithAlias<”%b”, A>;<o:p></o:p></p>
<p class="MsoNormal">def A: RegisterWithAlias<”%a”, B>;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, is there a way to specify that they are aliases of each other? Or does setting A as an alias of B also make sure that B is an alias of A?<o:p></o:p></p>
