[LLVMdev] Identifying recursive functions in a backend

[Robert Quill]

Hi,

I was wondering if it was possible to detect if a function is recursive in a back-end. For instance, I'd like to be able to say: "If this function we are about to call is recursive, store the return address to the stack, if it isn't we don't need a stack so do nothing". Does anyone know if this is possible?

Thanks,
Rob
