Subject: [PATCH] ArmPkg/ArmLib ARM: set .fpu to let Clang 7 assemble ArmV7Support.S
Date: Thu, 20 Dec 2018 20:16:53 +0100	[thread overview]
Message-ID: <20181220191653.8671-1-ard.biesheuvel@linaro.org> (raw)

Clang 7 complains about the vmsr instruction in ArmV7Support.S,
which is only available on cores that implement some flavour of
VFP. So set the .fpu to NEON like we do in some other places.
