Quoting Georg-Johann Lay <avr@gjlay.de>:

Is it ok to extend targetm.function_ok_for_sibcall so that it passes
also a pointer to the callee's CUMULATIVE_ARGS structure?


CUMULATIVE_ARGS is a target-dependent type, and thus every use of it
in the interface of target hooks should be considered a bug.
See PR46500.
