On gcc, __attribute__((cold)) means: - consider calls to the function to be unlikely for branch prediction - optimize the function for size - emit the function in a dedicated cold text section
It's not worth deleting these routines even though there are no longer in-tree consumers, but we can at least keep them out of i$ at runtime.
