1*5c2921b0SApple OSS Distributions#ifdef XNU_KERNEL_PRIVATE
2*5c2921b0SApple OSS Distributions// kern/kcdata.h gets its own top level module outside of the Darwin module
3*5c2921b0SApple OSS Distributions// to support building libkdd (one of our alias projects). libkdd can’t use
4*5c2921b0SApple OSS Distributions// <kern/kcdata.h> because it doesn’t produce that header itself, and so Xcode
5*5c2921b0SApple OSS Distributions// would pick up the old one in the SDK rather than mapping to the new one in
6*5c2921b0SApple OSS Distributions// SRCROOT. To get around that, libkdd uses <kcdata.h> to not match anything in
7*5c2921b0SApple OSS Distributions// the SDK and fall back on the one in SRCROOT. So far so good, but libkdd needs
8*5c2921b0SApple OSS Distributions// to avoid accidentally also picking up <kern/kcdata.h> via a module, or it
9*5c2921b0SApple OSS Distributions// will run into all kinds of redeclaration sadness that the include guards
10*5c2921b0SApple OSS Distributions// somehow don’t block. (Maybe because <kcdata.h> isn’t modular and
11*5c2921b0SApple OSS Distributions// <kern/kcdata.h> is?) libkdd uses the Darwin module, and so <kern/kcdata.h>
12*5c2921b0SApple OSS Distributions// needs its own top level module that sits on top of Darwin.
