...ns. The second problem with C++ templates is that every template instantiation always generates completely new code, even when it doesn't need to. Consider the following two functions: struct PairPtr<T> { T* first, T* second }; struct Pair<T> { T first, T second }; T* getSecondPtr<T>(PairPtr<T>* pair) { return pair->second; } T getSecond<T>(Pair<T>* pair) { return pair->second; } The generated code for getSecondPtr() is the same for every T. There is absolutely no need to generate a bazillion specialized copies. Notice that the .Net val...

Parametric polymorphism is different from subtype polymorphism; you can have one without the other. Parametric polymorphism just means that you can use type variables (like T) in the IR, which are later instantiated to

...example > of why it's needed in the host language, as is overloading. There's no reason why specialization -has- to be done by llvm. Idiotic languages like C++ can do it themselves, badly, if they want. ;-) I want llvm to do it for me because it can do a better job. ;-) >> void getSecond(int sizeT, void* pair, void* result) { >> return memcpy(result, ((char*) pair) + sizeT, sizeT); >> } > > Of course, that only works for POD types, so you still need a > different instantiation for std::string, std::vector, ...

I''ve just had a look again at the autocompletion demo that Thomas put up at http://script.aculo.us/demos/ajax/autocompleter Unfortunately, in Konqueror (3.4.1) it doesn''t work at all. Not even an error is triggered. It does work nicely in Firefox. How about Safari? I don''t have the time right now to track this down systematically (maybe latter), but just from
