            Bug ID: 23378
           Summary: Lacking documentation on -fapple-kext
           Product: clang
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

The -fapple-kext option specifies that clang generate kext codes for C++ files
instead of regular user-space codes. But this option is undocumented here and
elsewhere. 

I'm among those who believe that an overly-complicated language such as C++
should never be used to program a system kernel or a compiler, Much of the
esoteric features of C++ has complicated the implementations of the language. 

Although I'm fine with Clang being written in C++ since it's already capable of
self-hosting, I'd have a serious argument with someone if he uses it in system
kernel, especially when ABI is poorly documented.
