From: Nathan Chancellor Date: Thu, 12 Jan 2023 03:05:00 +0000 (-0700) Subject: MIPS: Prefer cc-option for additions to cflags X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=337ff6bb8960fdc128cabd264aaea3d42ca27a32;p=linux.git MIPS: Prefer cc-option for additions to cflags A future change will switch as-option to use KBUILD_AFLAGS instead of KBUILD_CFLAGS to allow clang to drop -Qunused-arguments, which may cause issues if the flag being tested requires a flag previously added to KBUILD_CFLAGS but not KBUILD_AFLAGS. Use cc-option for cflags additions so that the flags are tested properly.
