Subject: [PATCH 01/14] x86/boot/compressed: prefer cc-option for CFLAGS additions
Date: Wed, 04 Jan 2023 12:54:18 -0700	[thread overview]
Message-ID: <20221228-drop-qunused-arguments-v1-1-658cbc8fc592@kernel.org> (raw)
In-Reply-To: <20221228-drop-qunused-arguments-v1-0-658cbc8fc592@kernel.org>

From: Nick Desaulniers <ndesaulniers@google.com>

as-option tests new options using KBUILD_CFLAGS, which causes problems
when using as-option to update KBUILD_AFLAGS because many compiler
options are not valid assembler options.

This will be fixed in a follow up patch. Before doing so, move the
assembler test for -Wa,-mrelax-relocations=no from using as-option to
cc-option.
