<pre>
    An error enconted when I compiling an llvm pass.
In this pass, I go over all blocks in a function with api provided by DepthFirstIterator.h.
The error code in the pass as follows:
```
std::set<BasicBlock*> visitedSet;
for (auto i = df_ext_begin<BasicBlock*,std::set<BasicBlock*>>(&F.getEntryBlock(), visitedSet),
                e = df_ext_end<BasicBlock*,std::set<BasicBlock*>>(&F.getEntryBlock(), visitedSet);
                
                i != e; i++);
```
the error is:
It says that class set has no member named "completed". Is this a matter of my version of c++?
