Argyrios Kyrtzidis 8b6d86df06 Modifications to dyn_cast/cast to make them work for objects too, instead of only pointers. ... The use case is if you have a wrapper class: class Base { void *Ptr; public: Base() : Ptr(0) { } operator bool() const { return Ptr; } ..... } and sub-wrappers that have exactly the same size: class Sub : public Base { public: .... static bool classof(const Base*); } and in the code you would do: void f(Base b) { Sub sub = dyn_cast<Sub>(b); if (sub) { .... } } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78424 91177308-0d34-0410-b5e6-96231b3b80d8		2009-08-07 22:49:24 +00:00
