Yep. And Intel added a bunch of them to their compiler so that they
could build a kernel with it.
Why would you even attempt to convert the kernel sources to
be compiled with some other tools?
The Intel compiler is quite good at optimizing for their processors (and
ironically for AMD ones as well). However, I think that a lot of the
gains come from the vectorizer, which of course can't be used with
kernel code.
