Subject: [PATCH] kbuild: remove AS variable
Date: Wed, 25 Mar 2020 01:15:07 +0900 [thread overview]
Message-ID: <20200324161507.7414-1-masahiroy@kernel.org> (raw)
As commit 5ef872636ca7 ("kbuild: get rid of misleading $(AS) from
documents") noted, we rarely use $(AS) in the kernel build.
Now that the only/last user of $(AS) in drivers/net/wan/Makefile was
converted to $(CC), $(AS) is no longer used in the build process.
You can still pass in AS=clang, which is just a switch to turn on
the LLVM integrated assembler.
