In addition, 8d07479b2SMiguel Ojedasupport for building the kernel with LLVM/Clang varies (please see 9d07479b2SMiguel OjedaDocumentation/kbuild/llvm.rst). This support is needed for ``bindgen`` 10d07479b2SMiguel Ojedawhich uses ``libclang``. 11d07479b2SMiguel Ojeda 12d07479b2SMiguel OjedaBelow is a general summary of architectures that currently work.
