device_ptr construction from and convertibility to related types need to be protected by enable_if #309

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Certain type traits like is_convertible don't work correctly otherwise.

It seems like conversion from device_ptr<T> to device_ptr<U> is allowed right 
now, without any sort of cast.  This is dangerous and shouldn't be possible.

We should remove device_ptr's conversion operator (which cannot be protected by 
enable_if_convertible) in favor of a single constructor from device_ptr<U>, 
which can be protected.  We should get the same syntax minus the current unsafe 
behavior.  This could break user code, though.
