Subject: [PATCH 4.19 31/37] kbuild: remove AS variable
Date: Fri, 25 Sep 2020 14:48:59 +0200 [thread overview]
Message-ID: <20200925124725.652150808@linuxfoundation.org> (raw)
In-Reply-To: <20200925124720.972208530@linuxfoundation.org>
From: Masahiro Yamada <masahiroy@kernel.org>
commit aa824e0c962b532d5073cbb41b2efcd6f5e72bae upstream.
As commit 5ef872636ca7 ("kbuild: get rid of misleading $(AS) from
documents") noted, we rarely use $(AS) directly 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.
