Subject: [PATCH 05/11] ARM: vfp: use -mfloat-abi=soft to build vfp
Date: Sat, 1 Oct 2011 21:21:54 +0200 [thread overview]
Message-ID: <1317496920-7764-6-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1317496920-7764-1-git-send-email-arnd@arndb.de>
Distros are starting to ship with toolchains defaulting to
hardfloat. Using such a compiler to build the kernel fails
in the VFP directory with
arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP
Adding -mfloat-abi=soft to the gcc command line fixes this.
