Naked is related to TARGET_ALLOCATE_STACK_SLOTS_FOR_ARGS - ARM and RX
set the latter based on the former, and nobody else uses that target
hook. So, naked functions don't have stack slots for args. Without
stack slots, args can't be assigned to memory locations - even if
they're

Fails the same way with a parameter as with a local:
int result;
void __attribute__((naked)) ISRFunction(int x) {
result = subFunction(x);
}
but I'm certainly open to a better explanation of how a user program
can trigger an ICE that way.
Hmmm... the only use of

Thanks! Committed.
