3Arch Support
4============
5
6Currently, the Rust compiler (``rustc``) uses LLVM for code generation,
7which limits the supported architectures that can be targeted. In addition,
8support for building the kernel with LLVM/Clang varies (please see
9Documentation/kbuild/llvm.rst). This support is needed for ``bindgen``
10which uses ``libclang``.

12Below is a general summary of architectures that currently work. Level of
13support corresponds to ``S`` values in the ``MAINTAINERS`` file.
