Building Linux with Clang/LLVM
|
||||
==============================
|
||||
|
||||
This document covers how to build the Linux kernel with Clang and LLVM
|
||||
utilities.
|
||||
|
||||
About
|
||||
-----
|
||||
|
||||
The Linux kernel has always traditionally been compiled with GNU toolchains
|
||||
such as GCC and binutils. Ongoing work has allowed for `Clang
|
||||
<https://clang.llvm.org/>`_ and `LLVM <https://llvm.org/>`_ utilities to be
|
||||
used as viable substitutes. Distributions such as `Android
|
||||
<https://www.android.com/>`_, `ChromeOS
|
||||
<https://www.chromium.org/chromium-os>`_, and `OpenMandriva
|
||||
<https://www.openmandriva.org/>`_ use Clang built kernels. `LLVM is a
|
||||
collection of toolchain components implemented in terms of C++ objects
|
||||
<https://www.aosabook.org/en/llvm.html>`_. Clang is a front-end to LLVM that
|
||||
supports C and the GNU C extensions required by the kernel, and is pronounced
|
||||
"klang," not "see-lang."
|
||||
|
||||
Clang
|
||||
-----
|
||||
|
||||
The compiler used can be swapped out via `CC=` command line argument to `make`.
|
||||
`CC=` should be set when selecting a config and during a build.
|
||||
|
||||
make CC=clang defconfig
|
||||
|
||||
make CC=clang
|
||||
|
||||
Cross Compiling
|
||||
---------------
|
||||
|
||||
A single Clang compiler binary will typically contain all supported backends,
|
||||
which can help simplify cross compiling.
|
||||
|
||||
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make CC=clang
|
||||
|
||||
`CROSS_COMPILE` is not used to prefix the Clang compiler binary, instead
|
||||
`CROSS_COMPILE` is used to set a command line flag: `--target <triple>`. For
|
||||
example:
|
||||
|
||||
clang --target aarch64-linux-gnu foo.c
|
||||
|
||||
LLVM Utilities
|
||||
--------------
|
||||
|
||||
LLVM has substitutes for GNU binutils utilities. Kbuild supports `LLVM=1`
|
||||
to enable them.
|
||||
|
||||
make LLVM=1
|
||||
|
||||
They can be enabled individually. The full list of the parameters:
|
||||
|
||||
make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
|
||||
OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-size \\
|
||||
READELF=llvm-readelf HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar \\
|
||||
HOSTLD=ld.lld
|
||||
|
||||
Currently, the integrated assembler is disabled by default. You can pass
|
||||
`LLVM_IAS=1` to enable it.
