Summary:
Previously, if a function accepts an optional DT pointer,
```
void Foo (.., DominatorTree * DT = nullptr) {
...
if(DT)
DomTreeUpdater(*DT, ...).insertEdge(A, B);
if(DT){
DomTreeUpdater DTU(*DT, ...);
... // Construct the update vector and applyUpdates
}
...
if(DT){
DomTreeUpdater DTU(*DT, ...);
... // Construct the update vector and applyUpdates
}
}
```
After this patch, it can be simplified as
```
void Foo (.., DominatorTree * DT = nullptr) {
DomTreeUpdater DTU(DT, ...);
...
DTU.insertEdge(A, B);
if(DT){
... // Construct the update vector and applyUpdates
}
...
if(DT){
... // Construct the update vector and applyUpdates
}
}
```
