| Arch Support |
| ============ |
| |
| Currently, the Rust compiler (``rustc``) uses LLVM for code generation, |
| which limits the supported architectures that can be targeted. In addition, |
| support for building the kernel with LLVM/Clang varies (please see |
| Documentation/kbuild/llvm.rst). This support is needed for ``bindgen`` |
| which uses ``libclang``. |
| |
| Below is a general summary of architectures that currently work. Level of |
| support corresponds to ``S`` values in the ``MAINTAINERS`` file. |
