Its behaviour is also defined by the environment, so what gcc can assume
is rather limited and you have not shown a single example, that any such
assumption would be invalid for the kernel.

The kernel uses standard C, so your point is?
You already got two NACKs from arch maintainers, why the hell are you
still pushing this patch? The builtin functions are useful and you want to
force arch maintainers to have to enable every single one manually and
to maintain a list of these functions over multiple versions of gcc?
