Ugly. Wouldn't make a difference on i386, but other architectures actually don't need to play function-guessing games. Maybe we could create an architecture-provided function like void *get_next_stack_function(void* last_function); For asm-generic, this would do the i386 style stack guessing, while other architectures can walk a stack frame for it.
