Building with Bazel
===================
#. To build with Bazel, use the following command:
.. code-block:: sh
$> bazel build --config=generic_clang @llvm-project//libc/...
#. To run the unit tests with bazel, use the following command:
.. code-block:: sh
$> bazel test --config=generic_clang @llvm-project//libc/...
#. The bazel target layout of `libc` is located at: `utils/bazel/llvm-project-overlay/libc/BUILD.bazel <https://github.com/llvm/llvm-project/tree/main/utils/bazel/llvm-project-overlay/libc/BUILD.bazel>`_.
