Chris Lattner 2c6632d760 Add a simple type-safe bit-mangling pointer union class. This allows ... you to do things like: /// PointerUnion<int*, float*> P; /// P = (int*)0; /// printf("%d %d", P.is<int*>(), P.is<float*>()); // prints "1 0" /// X = P.get<int*>(); // ok. /// Y = P.get<float*>(); // runtime assertion failure. /// Z = P.get<double*>(); // does not compile. /// P = (float*)0; /// Y = P.get<float*>(); // ok. /// X = P.get<int*>(); // runtime assertion failure. llvm-svn: 67987		2009-03-29 06:06:02 +00:00
