That’s currently the case in C, in that you can convert pointers to and from uintptr_t. However, not every number representable in that type needs to be valid m

That’s currently the case in C, in that you can convert pointers to and from uintptr_t. However, not every number representable in that type needs to be valid memory (that’s true on the assembly level as well), hence it’s only defined for valid pointers.
