In this case, I think we need to figure out into which register could we load the address. Unfortunately, %rax or %eax isn't available for that, at least not always, e.g. for -m64 it can hold the saved static chain, the existence of __morestack_large_model shows that, but -m32 doesn't have anything like that. So, in theory for -fsplit-stack -mforce-indirect-call -m64 we could call __morestack_large_model even in non-large model compilations, just load the address of that function differently. For -m32, I'm out of ideas.
