--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess this is similar to the TLS ICE with -mforce-indirect-call. 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.
