fcf1b6a35c16ac5 Nick Desaulniers 2020-02-26 @13  The Linux kernel has always traditionally been compiled with GNU toolchains
fcf1b6a35c16ac5 Nick Desaulniers 2020-02-26  14  such as GCC and binutils. Ongoing work has allowed for `Clang
fcf1b6a35c16ac5 Nick Desaulniers 2020-02-26  15  <https://clang.llvm.org/>`_ and `LLVM <https://llvm.org/>`_ utilities to be
fcf1b6a35c16ac5 Nick Desaulniers 2020-02-26  16  used as viable substitutes. Distributions such as `Android
fcf1b6a35c16ac5 Nick Desaulniers 2020-02-26  17  <https://www.android.com/>`_, `ChromeOS
