<div dir="ltr"><div>Hi!<br></div><div><br></div><div>In my compiler I want to give user a list of user defined classes. I tried to use generated bitcode of my own wrapper of std::vector, but there is no possibility to generate bitcode of template, so I finally build it with std::vector<void*>. Do you know about any better solutions how to build such a type with llvm? Maybe there is a llvm built in type that is better choice than external c++ wrapper?</div>

Hi,
</div><div><br></div><div>Sorry, but I'm not sure I understand what you're trying to do. I guess you want some kind of superclass of some set of classes that are defined in the llvm api(?). In that case, which are specifically the types you could have in this list you're trying to define?</div>

<div>Hi,</div><div><br></div><div>
I guess you could use a template with a std::vector: you don't need to define right away the type, if you create a template of it.
</div><div><br></div><div>It should look something like that:</div><div><br></div><div>template<class B> class List {</div><div>std::vector<B> myList;</div><div>void insert (int pos, B elem);</div>
<div>}</div><div><br></div><div>template <class B> </div><div>void List::add (int pos, B elem) { </div><div> myList.insert(myList.begin()+pos, elem);</div><div>}</div>
<div><div><br></div><div>Then, wherever you'll use this class, you should define for which class B your class List should match (such as "List<int> intList;" or "List< std::vector<long> > longVectors;").</div>
