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.
