My question is how it works in this tablegen code which can only remember one of the values.
```
for (const Record *Equiv :
RK.getAllDerivedDefinitions("GIComplexPatternEquiv")) {
const Record *SelDAGEquiv = Equiv->getValueAsDef("SelDAGEquivalent");
if (!SelDAGEquiv)
continue;
ComplexPatternEquivs[SelDAGEquiv] = Equiv;
}
