Ah, thank you.


>Do we need that when we have exceptions in D?<

You are right. But maybe people that write a kernel may prefer to check error return values instead of using exceptions. Note this article was about GCC used to write the Linux kernel, that has different (and harder) requirements compared to application code, for example I think you don't need __builtin_return_address often in normal code.
