Subject: [Buildroot] [PATCH 25/31] arch/x86: get rid of BR2_GCC_TARGET_TUNE
Date: Mon, 20 Oct 2014 00:10:49 +0200 [thread overview]
Message-ID: <20141019221049.GF12247@free.fr> (raw)
In-Reply-To: <1413749285-1108-26-git-send-email-thomas.petazzoni@free-electrons.com>
Thomas, All,
On 2014-10-19 22:07 +0200, Thomas Petazzoni spake thusly:
> According to the gcc documentation, -march implies -mtune on x86, so
> defining both BR2_GCC_TARGET_ARCH and BR2_GCC_TARGET_TUNE is
> redundant. Therefore, this commit removes the definition of
> BR2_GCC_TARGET_TUNE on x86.
>
> However, while doing so, it adds one new case for BR2_GCC_TARGET_ARCH:
> using -march=generic when BR2_x86_generic is selected.
>
> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
