Hi Simon,

The function frame_register is used outside of frame.c in the rocgdb
downstream port.  Do you think we could revert this patch here?
Otherwise, this can be a change we keep downstream.

Best,
Lancelot.

I think it would make sense to make the function non-static in the
downstream port, and then provide a patch that makes it non-static
upstream when submitting the code that needs it outside of frame.c.
Here, I happen to be involved in this port, but that is what I would
answer to anybody else in the same situation.
